1 Changes in 1.4.7 (2024-04-07):
5 + When using *declination auto we report the range of calculated declinations
6 for each location specified. After doing this we now reset the range
7 information we're tracking. Previously we'd misreport the range for
8 the second and subsequent locations.
10 + Avoid undefined behaviour on handling filename fallback for filenames
11 containing non-ASCII characters.
13 + Show context line with relevant item highlighted for more errors and
16 + The dynamic string handling routines are now more efficient.
18 + Fix memory leak if a Compass MAK file opens folders it doesn't close.
20 + Fix handling of clino-less legs in Compass DAT. These would cause cavern
21 to fail with a lot of "NaN" messages. Now they're treated as having a zero
22 clino with a standard deviation based on the leg length, just like in .svx
27 + Compass PLT: Treat LRUD readings > 900 as omitted readings, which matches
28 what Compass does. Thanks to Larry Fish for clarifying this.
30 + Avoid undefined behaviour after realloc(). We were adjusting a pointer
31 within the reallocated block by subtracting the old block address and
32 adding on the new one. Technically this is undefined behaviour, although
33 in practice it seems likely it'll work and we've not seen misbehaviour due
34 to it. However it's easy to avoid by calculating the offset before the
39 + Provide prototype for getopt() to avoid warnings with very recent compiler
42 + Avoid using sprintf(), which now triggers warnings on some platforms.
46 + Add configure --enable-werror option to turn compiler warnings into errors.
50 + Expand details of Compass MAK CRS support.
52 + Replace very out of date information about binary RPM packages.
54 * Minor translation updates.
56 * (Microsoft Windows version): Now uses PROJ 9.3.0 and ships all of the
57 ancillary files that PROJ comes with. Hoping this fixes use of coordinate
58 system EPSG:3912 failing, which was reported by Peter Mašič but I've not
61 Changes in 1.4.6 (2024-03-07):
65 + Workaround bug in PROJ < 9.3.0 with projected coordinate systems with
66 northing/easting axis order (such as EPSG:3042) which results in the grid
67 convergence being wrong by about 90°. Reported by Patrick Warren on the
70 + If *declination auto was used before *cs out we would incorrectly calculate
71 the grid convergence as 0. We now handle this case correctly by
72 calculating lazily when we first read a compass reading, and report an
73 error if the output coordinate system hasn't been set by then.
75 + When opening a file, cavern has fallback handling if the file isn't found
76 to help people processing datasets from platforms with case-insensitive
77 file systems. Previously cavern would fold the filename to lowercase and
78 retry. Now if this fails, it will also try the lower case version but
79 with the initial character of the leaf in upper case, and finally folding
80 the whole specified filename to upper case.
82 + Dynamically pick a suitable level separator character and store it in .3d
83 file, instead of it being hard-coded to '.' (we still use '.' unless it
84 has been *set as a "name" character, or for Compass DAT/MAK files unless it
85 has been used in a station name). This is a step towards addressing the
86 situations raised by Thomas Holder in https://github.com/ojwb/survex/pull/4
87 and https://github.com/ojwb/survex/pull/5 .
91 - The shot flag S is now understood to indicate a splay.
93 - The shot flag P is now interpreted as marking surface data. This flag
94 is described as "Exclude this shot from plotting", but the use suggested
95 in the Compass docs is for surface data, and legs flagged with it "[do]
96 not support passage modeling". Even if it's actually being used for a
97 different purpose, Survex programs don't show surface legs by default so
98 the end effect is at least to not plot as intended.
100 - Surveys which indicate a depth gauge was used for azimuth readings are
101 now marked as STYLE_DIVING in the 3d file.
103 - Compass and clino corrections are now implemented for backsights.
105 - The tape correction in Compass DAT files is now handled correctly. The
106 specified value is in feet, but cavern was incorrectly treating it as
109 - We now handle the newer 15 character "FORMAT:" encoding. Previously
110 cavern wouldn't detect when there were backsights in this case.
112 - We now treat survey date January 1st 1901 as "no date specified" since
113 this is the date Compass stores in this situation, and it seems very
114 unlikely to occur in real data.
116 - In Compass DAT files a dummy zero-length leg from a station to itself is
117 used to provide a place to specify LRUD for the start or end of a
118 traverse (depending if dimensions are measured at the from or to
119 station), and so we no longer issue a warning about equating a station to
120 itself for DAT files.
124 - The base location command is now understood. This is how Compass
125 specifies a location to calculate magnetic declination at, and we
126 now handle this like Survex's native "*declination auto X Y Z".
128 - Survex uses the specified UTM zone and datum provided the combination can
129 be expressed as an EPSG code (lack of any EPSG codes for a datum suggests
130 it's obsolete; lack of a code for a particular datum+zone combination
131 suggests the zone is outside of the defined area of use of the datum).
132 Example Compass files we've seen use "North American 1927" outside of
133 where it's defined for use, presumably because some users fail to change
134 the datum from Compass' default. To enable reading such files we return
135 a PROJ4 string of the form "+proj=utm ..." for "North American 1927" and
136 "North American 1983" for UTM zones which don't have an EPSG code.
137 Please let us know if support for additional cases which aren't currently
138 supported would be useful to you.
140 - Folder commands are now understood.
142 - Flag fixed stations as entrances. Experimentation with Compass shows
143 this is how it treats them ("distance from entrance" in a .DAT file
144 counts from 0 at these points).
146 + We now support reading Compass CLP files. These are very like DAT files,
147 except they contain loop-closed data. You might find this useful if you
148 want to keep existing stations at the same adjusted positions Compass gave
149 (for example to be able to draw extensions on an existing drawn-up survey),
150 or if the original DAT file has been lost but you still have the CLP file.
154 + Fix OpenGL scaling on high DPI displays with wxWidgets 3.0. Reported by
157 + Split the filters for DAT and MAK files in the File->Open drop down list.
158 It seems more likely you'd want to see one type or the other, not both
163 + Fix survey filtering when reading Compass PLT files.
165 + .json,.kml: Enable export of surface legs. Currently surface and
166 underground legs aren't differentiated in these export formats when both
169 + .3d: The coordinate system is now set.
171 + .svg: Equated stations now get their correct names in the id attribute
172 of <circle> tags. Previously one of the names would be repeated for
173 all of a set of equated stations.
177 - Anonymous stations previously resulted in an empty name in the PLT
178 file. This isn't explicitly disallowed by the PLT format description,
179 but Compass' viewer gives an error for such lines. Now we invent names
180 by encoding the station coordinates which should be unique.
182 - The S shot flag is now set for splays, and the P shot flag (hide from
183 plotting) is set for surface legs (which matches the use suggested in the
188 + Fix bug handling timestamps before 1970. In C signed integer division
189 rounds towards zero, which previously resulted in timestamps before 1970
190 getting rounded to the end of the day instead of the start when converting
191 them to a count of days so they'd be off by one day unless the time was
192 midnight. This affected reading v3-v7 format 3d files with IMG_API_VERSION
193 set to 1 and writing v8 format 3d files with IMG_API_VERSION set to 0 (the
196 + Improve Compass PLT support (many of these are Compass features added
197 since Survex's support for Compass was originally added):
199 - Survey dates are now handled fully. We treat survey date January 1st
200 1901 as "no date specified" since this is the date Compass stores in this
201 situation, and it seems very unlikely to occur in real data.
203 - LRUD data is now translated to img_XSECT and img_XSECT_END.
205 - We now infer img_SFLAG_ENTRANCE for stations where the "Distance From
206 Entrance" field is present and zero.
208 - The shot flag L is now translated to img_FLAG_DUPLICATE.
210 - The shot flag S is now translated to img_FLAG_SPLAY. A station at the
211 far end of a shot flagged S gets img_SFLAG_WALL set since the Compass PLT
212 format specification says:
214 The shot is a "splay" shot, which is a shot from a station to the
215 wall to define the passage shape.
217 - The shot flag P is now interpreted as marking surface data. This flag
218 is described as "Exclude this shot from plotting", but the use suggested
219 in the Compass docs is for surface data, and legs flagged with it "[do]
220 not support passage modeling". Even if it's actually being used for a
221 different purpose, Survex programs don't show surface legs by default so
222 the end effect is at least to not plot as intended.
224 - The d plot command is now supported (previously img failed to parse
225 PLT files using this command) - it's like D but implies the P shot flag.
227 - If a PLT file only uses one datum and it is "WGS 1984" then the UTM zone
228 is converted to the appropriate EPSG code and this is reported as the
229 coordinate system. Other datums could be handled, but the mapping to
230 EPSG code is less simple. Also it seems Compass supports at least
231 24 datums but it doesn't document all the strings it uses for them.
232 Files with multiple datums could be handled too, but we'd need to convert
233 coordinates to a common coordinate system in the img library, which would
234 need it to depend on PROJ. Please let us know if support for more and/or
235 mixed datums would be useful to you.
237 - Duplicate img_LABEL items are no longer returned - this used to happen
238 for stations where more than two shots met within a single survey.
240 - We now infer img_SFLAG_EXPORTED for any station that appears in more
241 than one survey in the PLT file.
243 - We now set flag img_SFLAG_FIXED for any station which is listed as
244 a fixed point in the PLT file.
246 - If there's only one non-empty section name in a PLT file and we aren't
247 filtering by survey, we now report that section name as the title. If
248 there are multiple different non-empty section names, we still report the
249 basename of the file as before. If we're filtering by survey, we report
250 the comment for that survey as before.
252 - Fix bug handling PLT with omitted LRUD. The format specification
253 documents that LRUD may be omitted, though it seems Compass never
254 actually omits it and at least some versions of Compass failed to handle
255 it being omitted too.
257 * (Microsoft Windows version): Now using wxWidgets 3.2.4 (was 3.1.6).
261 + Document Compass support in detail.
263 + Improve NATO mils example.
267 + Add a link to the instructions for building from git. Reported by Andrew
268 Northall in https://github.com/ojwb/survex/pull/13
270 + Document the requirement for a C99 compiler for building from source.
271 We made this a requirement in 1.4.2, but only noted it in NEWS.
273 * doc/TODO.htm: Update.
275 * Replace references to "libav" with "FFmpeg" since the libav project seems to
276 now be defunct, and we've always supported using either.
278 * Update build system to eliminate use of obsolete autotools macros and drop
279 probes for features that we can safely assume now we require a C99 compiler
280 and workarounds for obsolete platforms.
282 * Fix compilation warnings from newer compiler versions.
284 Changes in 1.4.5 (2023-06-29):
286 * aven: Fix rendering of crosses when drawn as sprites. Reported by echarlie.
288 * (macOS version): aven: Fix crash in export dialog. Fixes #133, reported by
289 rixyane. Thanks to Wookey for testing.
291 * manual: Expand docs on connecting to Compass data.
293 * Minor translation updates.
295 Changes in 1.4.4 (2023-02-03):
297 * aven: Fix red line in clino background to be grey (this was introduced in
298 1.4.3 and was a debugging change accidentally left in).
300 * aven: Accept weird .3d files from Therion which have empty components in
301 station names. That's not really valid by Survex's definition of station
302 names, but it's not very helpful to reject such files, so just disable the
303 checks that were rejecting this.
305 The result is empty entries in the survey tree, but I don't see what we can
306 really do that's better than that.
308 Reported by Vasily Vl. Suhachev.
310 * aven: Make it more obvious you can enter a custom scale by adding a "..."
311 entry to the scale combobox - selecting this clears the value and gives focus
312 to the combo box text entry. This control has always supported clicking to
313 enter a custom scale, but there wasn't really any indication that this was
314 possible before. Partly addresses #132, reported by Eric C. Landgraf.
316 * aven: Force export window to resize when the export format is changed as
317 different controls are shown depending on the export format.
319 * aven: Right-align tilt spin control value in print/export dialog to match the
320 bearing spin control.
322 * aven,survexport: Add ability to export as Survex 3d which is useful as you
323 can filter to a subset of surveys, filter out splays, convert from other
324 formats the img library can read, etc. This feature is a bit rough and ready
325 currently but please report issues.
327 * dump3d: Add --legs option which converts MOVE and LINE to a single LEG line
328 per leg with the from and to coordinates. Tools which parse dump3d output
329 should find this easier to process as it avoids having to track a "current
332 * Update manual to have a complete list of quantities which *calibrate accepts.
335 * cavern.tst: Fix testsuite to work with SOURCE_DATE_EPOCH set.
337 Changes in 1.4.3 (2022-05-17):
339 * aven: Much improved support for HiDPI monitors on all platforms.
341 * aven: When started without a file make sure the window has focus so menu
342 accelerators and shortcuts work without clicking on the window.
344 * aven,survexport: DXF export now puts splays in a separate layer and uses a
345 dotted linetype for them. Patch from echarlie, see #60.
347 * Improved survexport man page to include command line options and a short
348 note about DXF export. Patch from echarlie.
350 * Minor translation updates.
352 * (Unix version): aven: Fix handling of EGL-based wxGLCanvas (which wxGTK 3.1.5
353 has). Fix a build failure and don't force X11 (as the EGL-based wxGLCanvas
356 * (MacOS version): aven: Fix hang on startup without a file. Fixes #120,
357 reported by Enrico Fratnik.
359 * (Microsoft Windows version): Now using wxWidgets 3.1.6 (was 3.0.5).
361 * img library: Support reproducible builds which create .3d files by not
362 embedding a timestamp if environment variable SOURCE_DATE_EPOCH is set.
363 Requested by Martin Budaj.
365 Changes in 1.4.2 (2022-02-25):
367 * aven: Fix to be compatible with FFmpeg 5.0.
369 * Improve docs for *cs and *declination.
371 * cavern: Fix "*declination auto" not to crash when built with PROJ < 8.1.0.
372 Bug introduced in 1.4.0.
374 * cavern: For each `*declination auto` command cavern now reports an "info"
375 message showing the range of calculated declination values and the dates at
376 which the ends of the range were obtained, and also the grid convergence
377 (which doesn't vary with time). Fixes #92, reported by Rob Eavis.
379 * cavern: If any of the N-S, E-W or U-D ranges includes an anonymous station
380 then also report the range in that direction excluding anonymous stations.
381 Patch from Thomas Holder.
383 * cavern: The error from a bad `*cs custom` command now highlights the quoted
386 * cavern: "FIX command with no coordinates - fixing at (0,0,0)" is now an
387 "info" rather than a "warning". It's not really reporting a problem and the
388 ability to omit the coordinates is a deliberate feature. It is useful for
389 the user to know where the "*fix" without coordinates is if they want to
390 change the survey to be in real coordinates, so an "info" diagnostic is a
391 good fit. This also means aven will no longer stay on the log view after
392 processing a dataset which fixes without coordinates.
394 * cavern: If "*fix" is used twice with no coordinates we no longer say
395 "FIX command with no coordinates - fixing at (0,0,0)" right before:
397 error: Already had FIX command with no coordinates for station "x"
399 * cavern: Include errors in Compass .mak files now report the error in the line
400 where the included filename is actually specified.
402 * cavern.tst: Add test coverage for warnings for *entrance and *export with
403 a station which doesn't exist otherwise.
405 * aven/survexport: Change JSON export to be valid JSON. This means the output
406 has changed incompatibly, but it wasn't valid JSON before which suggests
407 nobody was actually successfully using it. Fixes #128, reported by Pawczak.
409 * aven.tst: Skip one testcase on macos as it seems to hang, at least when
410 running on the Continuous Integration system.
412 * (Microsoft Windows version): The installer is now generated with a much
413 newer version of Innosetup. Most notably, it now supports installing as a
414 non-admin user. This also means Microsoft Windows Vista is now the minimum
415 supported version but 2000 and XP are both many years out of support anyway.
417 * (Microsoft Windows version): The coordinate system database for PROJ is
418 now included so "*cs" now works (broken since 1.4.0).
420 * Chinese translation updates from Qingqing Li.
422 * Building from source now requires a compiler with support for C99. C99
423 seems to be universally supported by compilers now so we don't expect this to
424 inconvenience anyone.
426 Changes in 1.4.1 (2021-11-08):
428 * This release should work with any PROJ version >= 6.2.0.
430 * cavern.tst: Fix to actually run tests when building outside the source
431 tree. Previously files for testcases weren't found, and tests were skipped
432 with a warning, which lead to 1.4.0 being released with two failing testcase.
433 Fix to find the files, and make not finding them an error.
435 * cavern.tst: Fix testcases gpxexport and require_fail which were failing
438 * 3dformat.htm: Document that coordinate system can be ESRI:<number>.
440 Changes in 1.4.0 (2021-11-06):
442 * New release series to mark that Survex now uses the new PROJ API, and
443 requires PROJ >= 7.2.0. Survex 1.2.x will continue to support PROJ < 8
444 (and won't support newer PROJ versions). Fixes #102, reported by Bas
447 Due to these changes, PROJ will now convert directly between coordinate
448 systems where it knows how to, instead of always converting via WGS84.
449 This means conversions may now be more accurate in some cases, and you may
450 notice station coordinates changing - these should be for the better.
452 Also, the vertical datum is now taken into account automatically, and
453 terrain data now aligns much better vertically with surveys. Fixes #56.
455 * aven: Clicking and holding the left mouse button on the compass or clino,
456 then (while still holding) clicking the right button no longer causes a
457 wxWidgets assertion to fail. Reported by echarlie.
459 * img library: Rewrite certain proj strings when reading 3d files for
460 better compatibility with newer PROJ versions, where use of proj
461 strings is strongly discouraged.
463 `+init=epsg:` followed by a code number is rewritten to `EPSG:`.
465 `+init=esri:` followed by a code number is rewritten to `ESRI:`.
467 The proj strings which cavern used to put in 3d files for UTM zones and
468 S-MERC are rewritten to `EPSG:` follow by the appropriate code number.
470 * Also install survex.lang for gtksourceview 4. Fixes #125, reported by Martin
473 * Fix missing data style in interleaved example in manual. Reported by
476 * Use jw from docbook-utils instead of sgmltools-lite to process the manual.
477 The sgmltools-lite homepage says it's no longer being developed, and suggests
478 docbook-tools (which Debian packages as docbook-utils) as a replacement.
480 * doc/HACKING.htm: Update Debian packages to install
482 * doc/HACKING.htm: Update details of setting up mingw cross-build environment.
484 * Add simple tests for GPX and KML export.
486 * Expand cavern testcase csbad.
488 * cavern.tst: Parse warning/error counts more robustly. Previously we'd get
489 confused if the final line just contained an integer, e.g. if we end listing
490 stations not attached to a fixed point.
492 Changes in 1.2.45 (2021-03-09):
494 * Avoid undefined signed shifts in 3d file handling. Survex itself is only
495 affected on big-endian platforms (so most Linux machine, Microsoft Windows,
496 and current Macs are all OK), but this also affects the img library on all
497 platforms when used in standalone mode as it is in other programs. Fixes
498 #119, reported by Matěj Plch.
502 + When reading cavern output for the log window, we need special handling
503 for the case when a chunk of output ends mid-way through a UTF-8
504 sequence. Previously we lost the first byte of the sequence in this
505 case (and would then show it as an invalid character), but now it is
506 handled correctly. In practice, most of the cavern log output is ASCII so
507 it's quite possible nobody's ever actually hit this.
511 + Suppress reports of leaks on exit from the LeakSanitiser debugging tool.
512 We know we don't release all memory explicitly on exit since doing so would
513 mean extra work for no reason as the OS reclaims all memory when the
516 * Convert OLDNEWS encoding from ISO-8859-1 to UTF-8.
518 Changes in 1.2.44 (2021-02-10):
522 + (Microsoft Windows version): Now using wxWidgets 3.0.5 (was 3.0.4).
526 * Add support for quadrant bearings (e.g. N30E). Patch from echarlie.
528 * Report error if angle units are specified for passage dimension.
529 Previously "*units left degrees" and similar were incorrectly quietly
530 accepted. Spotted by echarlie.
532 * Fix *data with no parameters to keep the current style and reset any state
533 as documented. Previously it actually instead ignored any survey data
534 until the next *data command with parameters.
536 * Fix minor memory leak in *data. We leaked a single memory allocation on
537 "*data default" or an invalid *data command.
539 * Improve test coverage.
543 * The check for whether a format supported --elevation, --plan, --bearing and
544 --tilt was inverted. Reported by echarlie.
546 * Fix reporting of export errors on Microsoft Windows. Reported by Matic Di
549 * img library: Fix img_open() when used in other programs. Patch from Thomas
552 * configure: Add wx-config-gtk3 to WX_CONFIG search for Arch Linux. Patch
555 * Improve documentation of interleaved data. Most notably, we now document
556 that a blank line breaks the current traverse.
558 * Fix typo in manual ('cypolar' -> 'cylpolar'). Patch from Wookey, fixes #117.
560 * Chinese translation updates from Qingqing Li.
562 * Russian translation updates from Vasily Vl. Suhachev.
564 * French translation updates from Jean-Marc and from Wassil Janssen.
566 * Bulgarian translation updates from Wassil Janssen
568 Changes in 1.2.43 (2020-02-28):
570 * cavern: Update to use v13 of the IGRF model for calculating declinations.
571 This was issued in December 2019 and should give slightly more accurate
572 declinations for surveys made since 2010.
576 + Fix colouring of "not in loop" when colouring by error. 1.2.42 introduced
577 a bug where surveys not in a loop were coloured as if they had zero error.
578 Fixes #111, reported by Bruce Mutton.
580 + Fix handling of grid in export. The grid was always getting enabled
581 (probably since 1.2.8) even for formats which don't support exporting with
582 a grid. This resulted in the bounding box being set wrongly for some
583 formats such as SVG, as reported by Richard Knapp on the mailing list.
585 + When showing errors processing the survey data we'd previously crash if
586 cavern incorrectly reported an error as being in a column off the end of
587 the line - now we just ignore the error column in this case.
589 + Support colouring by survey style ("normal", "diving", "nosurvey", etc).
591 Changes in 1.2.42 (2019-09-04):
595 + Allow colouring by horizontal or vertical error.
597 + (Unix version): Disable scaling for HiDPI displays with GTK3. The OpenGL
598 code needs work before this will work usefully, so just disable for now
599 (which simulates how things are when using GTK2).
601 + (Unix version): Fix orientation of notebook tabs when build with wxWidgets
602 3.1 development versions. We want horizontal tab orientation, but were
603 passing a weird flag combination which now results in vertical tab
606 * When exporting to a format where we support rotation in the horizontal
607 plane (such as SVG), the rotation was incorrectly applied to cross section
608 data (except for the default rotation of zero). Fixes #108, reported by
611 * Add a section to the manual covering the command line tools, and what you
612 might still need to use them for.
614 * Fix compiler warning when building from source with GCC 9.
616 * Consistently refer to macOS not OS X - Apple have renamed it yet again.
618 * (macOS version): Revert the workaround for the crash on macOS 10.14. The
619 bug we were working around is fixed in git ready for wxWidgets 3.0.5 and
620 there's a backported fix in the homebrew wxmac 3.0.4-2 package, which is how
621 we now recommend people install on a Mac. Closes #101, reported by floho.
623 * (macOS version): Remove buildmacosx.sh script since installing from homebrew
624 is now the recommended approach.
626 Changes in 1.2.41 (2019-07-10):
630 + (Microsoft Windows version): Fix error on startup in the pre-built version
631 of 1.2.39 and 1.2.40. This is a recurrence of the same issue as affected
632 1.2.33 - this time I've patched out the unnecessary check in wxWidgets
633 which causes this problem so it shouldn't recur again. Reported by
636 + (macOS version): Add work around for crash on macOS 10.14 (not fully tested
637 as I don't have access to a Mac). Hopefully fixed #101, reported by floho.
639 Changes in 1.2.40 (2019-07-04):
641 * aven: Draw the measuring line ring with an even shape. Previously the exact
642 shape of the ring varied slightly depending on the exact coordinates, which
643 could be visually distracting once you noticed it.
645 * We were casting a function pointer with a bool return type to the same type
646 but with a void return type. In practice this probably works fine on most
647 platforms, but it's undefined behaviour and also gives a compiler warning
650 * Fix bug introduce in 1.2.39 with where the "esri" data file for PROJ is
653 Changes in 1.2.39 (2019-06-29):
655 * Support versions 5.x and 6.x of the PROJ library we use for handling
656 conversions between coordinate systems. Reported by Bas Couwenberg
657 in #102, by Richard Knapp in #103 and by Martin Sluka in email.
659 * (Unix and Mac OS versions): When checking if something is a file or if it is
660 a directory, we no longer treat a symlink as being neither, but instead
661 return an answer based on what the symlink points to.
665 + Improve handling of hidden splay ends. Previously, hidden splay ends still
666 served as "targets" for snapping the mouse pointer to, and still got
667 crosses when crosses were enabled. We don't have a handy flag for "this is
668 the outer end of a splay" and computing that on demand isn't so easy to do,
669 so for now we use the "anonymous station" flag so at least these cases now
670 behave properly for splays to anonymous stations (which is likely to be
671 what people with huge numbers of splays from disto-x, etc are using). This
672 does mean that anonymous stations on continuation passages will incorrectly
673 also be off when splays are hidden, but that seems an OK trade-off for now
674 and a definite improvement over the previous situation. The snapping of
675 the mouse pointer was reported by Frank Tully in #105.
677 + Fix typo in export UI (CVS should be CSV).
681 + Add CSV to documented list of survexport output formats.
683 + Fix *declination syntax synopsis - "auto" is a literal string, not a
686 + Update PROJ project name and website - the name is now "PROJ" (all caps and
687 no ".4" suffix) and the website is now: https://proj.org/
689 * Install gtksourceview-3.0 language file so .svx files now get syntax
690 highlighting in gedit and other GtkSourceView-based editors. Patch
691 from Philip Withnall. Fixes #98.
693 * (Microsoft Windows version): The Survex installer doesn't uninstall the old
694 version when you upgrade, but just overwrites it with the new version. In
695 1.2.35 cad3d.exe was replaced with survexport.exe, but a user upgrading from
696 an older version would still have cad3d.exe from that old version. We now
697 remove any old cad3d.exe left over from a previous install in the same
698 location to avoid confusion.
700 * Add a few more message translations.
702 * Fix warnings when built with a C++11 compiler.
704 Changes in 1.2.38 (2019-03-02):
708 + Deprecate MILS as angular units. Survex has long support MILS as an alias
709 for GRADS. However, this seems to be a bogus definition of a "mil" which
710 is unique to Survex (except that Therion has since copied it) - there are
711 several different definitions of a "mil" but they vary from 6000 to 6400 in
712 a full circle, not 400. Reported by Andy Edwards.
714 + Fix segfault for *include "". This isn't useful, but shouldn't crash. It
715 now reports "file not found" instead.
717 + Use isnan() to check for not-a-number. This is cleaner, more robust and
718 more efficient than formatting the number as a string and checking for
719 "NaN" or "nan" in the result.
721 * Avoid unused variable warning when compiling from source with modern ffmpeg.
723 * Drop support for wxWidgets < 3.0. 3.0.0 was released over 5 years ago and
724 should be easily available everywhere by now. I'm no longer easily able to
725 test with wxWidgets 2.8, and this allows a significant amount of cruft to be
728 * (Linux version): survex.spec: Fedora have removed gcc from the default build
729 environment so need to explicitly list it in the BuildRequires tag. See
730 https://fedoraproject.org/wiki/Changes/Remove_GCC_from_BuildRoot for more
731 information. Patch from James Begley.
733 Changes in 1.2.37 (2018-11-18):
737 + Add basic "Colour by Survey" feature. The colours used aren't currently
740 + Fix export of splays. Patch from Thomas Holder.
742 + Fix KML export to avoid invalid geometry when a tube intersects itself.
743 Patch from Robert Jones.
745 + (Unix version): Fix to work under Wayland by forcing the x11 GDK backend
746 for now. This is a workaround until wxWidgets OpenGL support is updated
747 to work under Wayland. Reported by Philip Balister.
749 + Fix warnings about using deprecated functions when building movie export
750 code using FFmpeg 4.0.
754 + Compass MAK files: Handle fixed point coordinates in feet - previously the
755 units were ignored and the coordinates assumed to be in metres.
757 + Previously the first byte in a MAK file was ignored. Typically MAK files
758 start with a comment, and since cavern currently ignores lines that start
759 with characters it doesn't understand the meaning of, this bug would often
764 + Fix exporting of passages, walls and cross-sections by running the code
765 aven uses to decide how much to rotate each cross-section. Previously all
766 cross-sections were aligned West-East. Reported by Robert Jones.
768 + Default to .pos output if the program name is 3dtopos, and install a second
769 copy (or hardlink under Unix) as 3dtopos. This provides compatibility with
770 current releases of Tunnel. Reported by Becka Lawson, Wookey and
773 * Fix some German translations. Patch from Thomas Holder.
775 * (MacOS X version): Fix aven-create-app to not delete converted icons.
776 Typo spotted by Robert Jones.
778 * Improve documentation for *team. Document the requirement to quote names
779 unless a person is identified by just one name. Document that the roles are
780 optional, as that information may not have been recorded, and to align with
781 therion's team command.
783 Changes in 1.2.36 (2018-07-18):
787 + Add support for exporting as a CSV (Comma-Separated Values) file.
789 + Support exporting KML with altitude mode "clamp to ground". In this mode,
790 the altitude in the data is ignored and it's rendered on the surface of the
791 terrain. This is useful if your KML viewer renders the terrain as opaque
792 so underground data isn't visible. Rendering cave passages on the surface
793 isn't great, but is better than not being able to see them at all. This
794 option may also be helpful if you want to see where to look on the surface
797 + Highlight surveys with a white loop as the mouse is moved over them in
798 the survey tree. This is akin to how we highlight a station with a
799 white ring, and allows restoring "double-click survey in tree to zoom"
800 which temporarily required a quadruple-click in 1.2.35.
802 + Only show checkboxes in the survey tree for surveys not stations.
804 + Fix wxWidgets assertion if the user tried to select additional surveys
805 to show via the right-click menu.
807 + Fix multiple survey filtering when both a parent and child survey are
808 selected. In this case it makes most sense to show all child surveys of
809 the parent, but we actually showed a slightly arbitrary subset of the
810 child surveys of the parent.
812 + The checkbox area in the survey tree is now included in the area which
813 is considered by mouse-over updates such as highlighting the station or
816 + Fix display of double quotes in cavern log window (they were being replaced
817 with control character 0x16 due to a typo in the code).
819 + Add shortcuts to buttons in cavern log window.
821 + Eliminate use of gluErrorString() function which eliminates some
822 deprecation warnings when building on macOS.
824 + Reject multiple --survey command line options for now (only the last has
825 been used for a long time, but now we actually support multiple survey
826 filtering this matters more).
830 + Report a useful error when trying to convert a .3d file without coordinate
831 system information to GPS. Reported by Mark Shinwell.
833 + Handle multiple redundant --survey command line options correctly.
835 * dump3d: Report station flag "WALL", which was added in 1.2.7.
837 * Minor translation updates.
839 * Update manual for Microsoft Windows changes.
841 * tests/: Add test coverage for warnings about suspect readings
843 * Fix warning when compiling with clang.
845 Changes in 1.2.35 (2018-07-03):
849 + Viewing can now be restricted to multiple surveys. Use the right-button
850 menu on a survey in the survey tree and select "Show" to enable checkboxes
851 for that survey and all its siblings. Only the selected surveys are shown
852 on screen, printed and exported.
854 + Don't open a survey when its name is double clicked. This was happening
855 due to code added to "allow double-clicking to work on wxMSW >= 2.8.11".
856 However, reverting that change still seems to allow double-clicking to work
857 on both wxMSW and wxGTK, but fixes the unwanted additional opening of the
860 + Pick initial survey scaling based on whichever of the window width or
861 height gives the smaller scale. Previously we always used the window
862 width, which can result in parts of the cave being outside the initial
863 view. Reported by Wookey.
865 + Drop ability to specify a PROJ string in the export dialog. This was added
866 to allow exporting to formats such as GPX before we added support for
867 specifying the projection in .svx files, and that support is now mature.
869 + DXF export now uses 2 decimal places (was 6) for the bounding box, for
870 consistency with the precision used for coordinates.
872 + Fix handling of surface flag during export. In formats which discriminate,
873 legs could previously have got assigned the wrong status.
875 + Fix bug which probably prevented aven starting when OpenGL double buffering
876 is unavailable. This is unlikely to affect any common configurations.
878 + (Microsoft Windows version): Fix loading of 3d files with non-ASCII
879 filenames. Issue reported by Matic.
881 + (Microsoft Windows version): Fix incorrect display of some toolbar icons.
882 Probably broken since 1.2.17.
884 * survexport: New command-line export program which uses aven's export code.
885 Replaces 3dtopos, cad3d and findentrances, since it can do all that these
886 tools could do, plus much more.
888 * Merge more Spanish i18n updates from Evaristo Quiroga.
890 * Minor updates to various other translations.
894 + Now supports reading from and writing to an existing FILE*.
896 + Improve API documentation.
898 * (Microsoft Windows version): Fix packaging to include wxWidgets translation
899 files like it was supposed to, which fixes a few missing translations. This
900 was probably broken by changes in 1.2.8. Reported by Evaristo Quiroga.
902 * (Microsoft Windows version): Drop two options from explorer bindings.
903 "Convert to DXF" and "Convert for hand plotting" have both been supported via
904 aven for a while, and that's a more useful way to access them as you can
905 control what gets exported.
907 Changes in 1.2.34 (2018-03-24):
911 + (Microsoft Windows version): Fix error on startup in the pre-built version
914 + (Microsoft Windows version): Now using wxWidgets 3.0.4 (was 3.0.2).
916 Changes in 1.2.33 (2018-03-22):
920 + Reliably disable scale bar in perspective view. This is supposed to happen
921 (because the scale across the screen varies in perspective view) but
922 actually the scale bar stayed around until an update was forced for another
923 reason. Spotted thanks to Pedro Silva Pinto.
925 + Make "no date"/"not in loop" colour grey. The white was a bit bright and
926 made it harder to see the legs that had colours. The grey now used is
927 within the brightness range of the other colours. Fixes #94, reported by
930 + Fix KML export - exporting both survey legs and station names resulted in a
931 malformed KML file. This bug was introduced in 1.2.30 when support for
932 exporting passages and walls was added. Reported by Erin Lynch in #90.
934 + Consistently use 2 decimal places for altitude in KML output. Some places
935 used 8 decimal places which is appropriate for lat and long, but clearly
936 overkill for an altitude in metres and increases the file size
939 + Right-align bearing widget in print/export dialog. The change to allow the
940 value to wrap round from 360 to 0 in 1.2.27 inadvertently made this control
941 left-aligned (due to incorrect wxWidgets documentation of the default style
944 + (Unix version): Work around wxWidgets bug so that custom cursors work
947 + (Unix version): Update GTK version reporting - report GTK3, and don't
948 bother to report subversions of GTK2 (it seems to be fairly arbitrary
949 which subversions wxWidgets defines constants for).
951 + Update code to work without warnings when using wxWidgets 3.1.0 (the
952 current development version).
954 + Make movie export code compatible with upcoming FFmpeg 3.5 release.
955 It should still work with the older versions that worked before this
956 change. Reported by James Cowgill in https://bugs.debian.org/888334
960 + Warn about 2 digit years. We can't change the assumption that these are
961 19xx without risking breaking existing datasets, but the further we get
962 into this century, the more likely such an assumption is to catch someone
963 out. The warning can easily be quashed by explicitly adding the assumed
966 * The Spanish translation is now up to date once more, thanks to updates from
969 * Merge French translation updates from Jean-Marc.
971 * Fix transposed German Northing and Easting labels. Fixes #95, reported by
974 * Fill in missing translations of "Easting", "Northing", "E" and "N" for
975 Bulgarian, Greek, Hungarian, Polish and Russian based on other existing
978 * Align .pos file headings better with columns of coordinates below for
979 Indonesian and Polish.
981 * Fix handling of the message string "error" before messages loaded. If
982 there's an error loading messages, we need this message to report it.
983 Reported by Martin Sluka.
985 * Fix a few compiler warnings.
987 * img library: Fix extracting leaf survey name for survey title. When there
988 are three or more levels of survey, we were taking everything after the first
989 dot rather than everything after the last dot.
991 * Fix problems with testsuite on macOS:
993 + cavern.tst: Skip "ONELEG" testcase on case-insensitive filing systems
994 - this test isn't meaningful unless the filing system is case-sensitive,
995 but happens to fail if it isn't.
997 + cavern.tst: Workaround limitations of Apple's sed.
999 + aven.tst: Fix not to hang on macOS.
1001 + smoke.tst: Remove aven testcases which duplicate those in aven.tst.
1003 * Clean up handling of support files in relocatable installs - this is now
1004 detected at run time on macOS.
1006 * Split out macOS Aven.app creation into a make rule so it can be easily used
1007 by the homebrew formula.
1011 + Fix when WX_CONFIG not specified - this was giving a confusing error like:
1012 ./buildmacosx.sh: line 163: --cc: command not found
1014 + Use wxWidgets 3.0.4.
1016 * Stop checking wx-config --ldflags as this option was removed in wxWidgets 2.6
1017 and we currently require 2.8 or newer.
1019 Changes in 1.2.32 (2017-07-08):
1023 + Make splays on printouts a darker shade of grey. Reported by Erin Lynch
1026 + In export formats which include 3 dimensions (DXF, PLT, GPX, KML, JSON,
1027 POS), the value in the Z dimension was negated. Bug introduced by fixes
1028 for export of rotated plans and tilted elevations in 1.2.27. Reported by
1031 + Ignore viewing angles for export formats which work in 3D. When the
1032 rotation and tilt controls are hidden in the export dialog we were still
1033 using their values to transform the data, so if you set them with for one
1034 export format which support them, then switched to an export format which
1035 doesn't, you'd get bogus coordinates in the exported file. Bug probably
1036 introduced in 1.2.27 by fixes for exports of rotated plans and tilted
1039 + Fix exporting to skencil and Survex .pos formats. When aven's export to
1040 .pos was added in 1.2.19, the ordering didn't match up and since then .pos
1041 export has produced skencil files and vice versa.
1043 + Don't leave terrain on if loading terrain data fails. Previously if you
1044 clicked the terrain icon (or via the menu) with no terrain loaded, but no
1045 terrain got loaded (e.g. because the survey data lacks an explicit
1046 coordinate system, or because the file failed to load, or because you
1047 cancelled the dialog) then the terrain icon/menu item was still changed to
1050 + Disable texturing while drawing terrain. Previously the terrain got a bit
1051 darker when "Textured Walls" were enabled.
1053 + Force a refresh when "Textured Walls" are enabled or disabled. Previously
1054 the display wouldn't update right away.
1058 + Document how to specify fixed point altitude in feet.
1060 + Explain why *fix warns about unused fixed points
1062 * Building from source now requires a compiler with decent support for C++11.
1063 If you're using GCC, then GCC 4.7 should suffice. This should not be an
1064 onerous requirement - e.g. Debian wheezy and Ubuntu trusty both have a recent
1065 enough GCC. If special options are needed, these should get probed for and
1066 automatically. Fixes building 1.2.31 with GCC < 6, reported by Wookey.
1068 Changes in 1.2.31 (2017-07-01):
1072 + Use superscript 'g' symbol instead of word 'grads' in status bar. This
1073 conserves the limited space available, and we already do this in the
1074 compass and clino indicators so it's more consistent too.
1076 + Show one decimal place on measure line bearing. Pointed out by Benedikt
1077 Hallinger on the therion list, though I'm sure this has been asked for
1080 + Show gradient of the measuring line when both ends are stations.
1082 + Allow selection of text in cavern log window. Selection was disabled in
1083 1.2.28 because it seemed you couldn't actually copy selected text to the
1084 clipboard, but retesting this now actually works fine for me, both with
1085 current git master with the change reverted, and with code just before the
1088 + More robust parsing of cavern output (cleanly handle context highlighting
1089 which extends beyond the end of the line).
1091 + Allow showing duplicate legs as dashed lines or hiding them entirely,
1092 with dashed now being the default. Implemented by Patrick Warren.
1094 + Also allow "Dashed" for splays and "Faded" for duplicate legs.
1096 + Splay legs in surface data are also shown faded.
1098 + Check environment variables VISUAL and EDITOR when looking for editor to
1099 use when a warning or error is clicked on in the cavern log window. The
1100 specified editor may have a GUI or need to run in a terminal, so we have to
1101 special-case each editor supported, and that means we can pass extra
1102 options needed to position the cursor on the appropriate line/column.
1103 Currently these editors are supported: gvim, nvim, vim, gedit, pluma,
1104 emacs, nano, jed, kate. Suggested by Wookey.
1106 + Fix handling of non-square terrain data files - the X and Y dimensions were
1107 swapped. Reported by detrito.
1109 + Improve parsing of DEM data with .hdr file. Use documented defaults for
1110 more values, and where we only support a subset of values (or a particular
1111 value) check for unsupported values in more cases.
1113 + When colouring by depth, fix colouring and texturing of polygons which
1114 cross depth bands. The previous problems were most obvious with high
1115 chambers and long legs down deep pitches, especially in for surveys without
1116 much vertical range.
1118 + Support for drawing blobs using point sprites was added in 1.2.28,
1119 but caching that this worked wasn't hooked up properly so the test to
1120 see if this worked would happen at the start of each run. This is now
1121 cached as intended which should reduce start up time a little when blobs
1122 are drawn in this way.
1124 + Fix drawing of crosses with lines. This is a fall-back case which is
1125 rarely used as most OpenGL setups will handle a better method, but it was
1126 resulting in crosses with a four-pixel square in the centre - now the
1127 centre should be a single pixel.
1131 + Allow *data with no arguments to reset the current style - useful for
1132 entering passage data where there are side passages.
1134 + Fix hang processing file without newline at end. This bug was introduced
1135 by changes in 1.2.28. Reported by Mark Brown.
1137 + (Mac OS X and Microsoft Windows versions): Build with newer version of
1138 PROJ library which fixes buggy handling of *fix with lat-long coordinates.
1139 Also add a testcase to the testsuite to alert users building for themselves
1140 with an affected PROJ version on any platform. Reported by Ross Davidson.
1142 + Fix cavern to handle Compass .DAT with no survey team. Previously this
1143 resulted in the bogus error: Expecting numeric field, found "FROM"
1144 Reported by Erin Lynch.
1146 + Handle UTF-8 "BOM" at start of .svx files. Unicode doesn't recommend its
1147 use, but Microsoft stuff seems to like to create files with it in, and the
1148 error cavern currently reports for such files is very confusing, so it
1149 seems best to just handle it. Reported by Rob Eavis.
1151 + Change a couple of messages to use double quotes for consistency with all
1156 + Now runs a bit faster.
1158 + Splays are now carried over the extended survey. The current handling
1159 is simplistic, but should do a good enough job to be more useful than
1160 discarding splays. The splays at each station are all rotated together
1161 based on the bearing between the stations either side of the current one
1162 along the first path extended through that station. This nicely handles
1163 dead ends and the situation at the top or bottom of a pitch, and should
1164 tend to pick an angle close to the passage orientation along a traverse.
1165 It's weakest at junctions. Feedback (especially examples which could
1166 be handled better) most welcome.
1168 * French translation is now up to date again, thanks to Jean-Marc.
1170 * Remove erroneous menu shortcut markers from Polish translations.
1172 * Fill in some missing translations in several languages by using message
1173 translations from therion.
1175 * Add note to *fix documentation to clarify the coordinate order with *cs
1176 long-lat. Issue raised by Ross Davidson.
1178 * Fix errors in documentation of *units: "DEG" should be "DEGS", and
1179 "MINUTES" has been supported for ages but wasn't documented. Reported by
1182 * Fix a few typos in the documentation.
1184 * Fix compilation warning with recent GCC.
1186 Changes in 1.2.30 (2016-10-03):
1190 + (Microsoft Windows version): Fix crash when trying to print or export
1191 (probably introduced in 1.2.28). Reported by Brian Clipstone.
1193 + Report error if terrain file contains no terrain data in area of survey.
1194 Suggested by detrito.
1196 + Errors when writing an export file were reported with the wrong filename
1197 - the .3d file, not the filename we were trying to write to.
1199 + Export to KML now supports exporting passages, walls and cross-sections.
1200 Addresses the remainder of ticket #4.
1202 * Add man page for dump3d.
1204 Changes in 1.2.29 (2016-09-27):
1208 + Fix SVG output with non-ASCII characters (the charset in the SVG file
1209 is now set to UTF-8 not ISO-8859-1).
1211 + (Microsoft Windows version): Fix error dialog on startup in pre-built
1212 version. Reported by Brian Clipstone.
1214 * Manual: Add link to TerrainData wiki page. Omission highlighted by Erin
1215 Lynch and "detrito".
1217 * Fix to build without FFmpeg/libav and with older versions, broken by changes
1218 in 1.2.28. Reported by James Begley.
1220 Changes in 1.2.28 (2016-09-24):
1224 + Show the contents of the line after error and warning messages while
1225 processing survey data, and indicate the region of the line in many cases
1226 in the same style that compilers such as GCC and clang use (using the
1227 column number we already have, plus new width information). Based on a
1228 patch from Mateusz Golicz.
1230 + Add column and width information for many more error and warning messages.
1232 + Fix column for "Separator in survey name" warning.
1234 + Improve warnings when using a backclino with range 0-180 degrees (reusing
1235 the same machinery we already have for a forward clino with range 0-180
1240 + Include LRUD in printout/export of extended elevations, broken by
1241 improvements to export of tilted elevations in 1.2.27. Reported by Anthony
1244 + Name <trk> tags in GPX output, so Garmin GPS units name the imported track
1245 usefully. Reported by Anthony Day.
1247 + Remember scale from previous print or export operation in the same run of
1248 aven. Suggested by Stuart Bennett.
1250 + Convert range indication below shown line to a highlight on that region
1251 of the line in cavern log window.
1253 + Fix colouring of error/warning without column in cavern log window.
1255 + Fix click on error/warning without column in cavern log window.
1257 + Fix highlight of translations of "error" or "warning" containing non-ASCII
1258 characters. This fix for this only works with a Unicode build of
1259 wxWidgets, but as of wxWidgets 3.0, all builds are Unicode, so this
1260 shouldn't be much of a problem as wxWidgets 2.x is close to obsolete now.
1261 Reported by Mateusz Golicz.
1263 + Disable selection of text in cavern log window - you can't currently copy
1264 it to the clipboard, so until that's implemented it seems better to disable
1265 the ability to select it. Reported by Wookey.
1267 + Avoid special "1000" scale entry when exporting.
1269 + Show 1 page when "One Page" selected.
1271 + Reload processed data when restricting view. Fixes failure when
1272 restricting view on data just processed via aven. Spotted by Andrew
1273 Atkinson and myself.
1275 + Don't hide blobs and crosses behind terrain. Reported by Jenny Black.
1277 + Fix rendering of crosses using point sprites. The texture being used was
1278 misaligned relative to the image used for the visual fidelity check, so the
1279 check always failed and point sprites would never be used. Where point
1280 sprites are supported, they're probably the fastest option - on my netbook
1281 this change improves FPS by ~6 fold when displaying crosses for a large
1284 + Support drawing blobs using point sprites. About 5 times faster than using
1285 lines on my netbook.
1287 + Recheck how best to draw crosses and blobs on the first run after Survex
1288 is upgraded (or downgraded) as the rendering code may have changed (we
1289 already recheck when the OpenGL hardware or driver changes).
1291 + Change "MPEG" export to be MPEG4 (.mp4) rather than MPEG1 (.mpg).
1292 MPEG4 produces smaller output of higher quality, and should be widely
1293 supported these days. And I can't get the MPEG1 output to work without
1294 buffer underflows, resulting in a file which doesn't play without
1297 + Add OGG video to the list of formats - it's more compact than the others
1298 we currently list, though slower to write.
1300 + Fix export to movie formats for which libav/FFmpeg needs to seek the file
1301 being written. This was broken by changes in 1.2.27.
1303 + Overhaul movie export for the current FFmpeg API, fixing deprecation
1304 warnings when building against a recent version.
1306 + (Microsoft Windows version): Fix corrupted exported movie files. 1.2.27
1307 changed the movie export code to allow writing to files with non-ASCII
1308 characters in the names, but the new code failed to open the file in binary
1309 mode, leading to corrupt output. Fixes #81, reported by Erin Lynch.
1311 * (Microsoft Windows version): Pre-built version now uses FFmpeg 3.1.3 for
1314 * (Mac OS X version): Pre-built version now uses FFmpeg 3.1.3 for movie
1317 * Fix to build without FFmpeg/libav, broken by changes in 1.2.27. Reported by
1320 * The Polish translation is now very close to being complete, thanks to a
1321 substantial update from Mateusz Golicz.
1323 * Merge catalan translation updates from Adolfo Jayme.
1325 * (Microsoft Windows version): Map LANG_CHINESE to zh_CN not zh so Chinese
1326 messages get used automatically.
1328 * cavern.tst: Remove random : from after ] - dash ignores the extra character,
1329 but it causes this test to fail if /bin/sh is a different shell (e.g. bash).
1331 * cavern.tst: Add expected output for more testcases.
1333 * Remove unwanted execute bit from some testcase data.
1335 * Use https for more URLs which support it.
1337 Changes in 1.2.27 (2016-06-06):
1341 + Right click on a survey in the survey tree now gives a pop-up menu
1342 with "Hide others", which restricts the view to just that survey
1343 and any subsurveys. Right click on the root of the survey tree
1344 gives a menu with "Show all" to undo any restriction in effect.
1345 (Currently these are implemented by reloading the file and using
1346 the same machinery as the --survey= command line option, but that will
1347 probably change in the future).
1349 + If there's a sub-survey restriction (from the --survey= command line
1350 option or the new UI described above) it is now shown in brackets after
1351 the survey tree root.
1353 + When reloading a survey, preserve the current view position (previously
1354 the view was recentred).
1356 + When reloading a survey, actually preserve the current scale factor
1357 (this was meant to happen, but the adjustment was applied in the
1360 + New "File->Extended Elevation..." menu item provides a way to generate
1361 extended elevations for simple cases without having to use the command
1362 line. Suggested by Fleur Loveridge.
1364 + Don't process key presses if accompanied by an unexpected modifier key.
1365 In particular, this means that aven no longer interferes with Alt+<function
1366 key> (which is typically handled by the desktop) and Alt+<letter> (which is
1367 typically a menu short cut). Reported by Владимир Георгиев.
1369 + Reduce file loading time by ~5%. The station name compare function was
1370 something of a hot spot, and optimising it yielded a nice improvement.
1372 + Allow splay legs to be disabled in when printing and exporting. Mostly
1375 + SVG export now shows splay legs thinner and in grey. See #60.
1377 + Fix export of rotated plans and tilted elevations - previously plans were
1378 always aligned with North up, and elevations which weren't exactly side on
1379 were exported as plans. Reported by Stuart Bennett.
1381 + Fix offset bounding box for exported elevations.
1383 + In print/export dialog the bearing value now wraps if you scroll up past
1386 + Fix greying out of LRUD-based controls in the print/export dialog when the
1387 view is tilted (i.e. not plan or elevation). This stopped working in
1388 1.2.18 when the pan and tilt spin controls were changed from integer- to
1391 + Printouts now show LRUD as pale grey arrows from the station they are
1392 measured from. Based on patch from Michael Sargent. Closes #65.
1394 + Take LRUD into account for printout size. Fixes #72, reported by Erin
1397 + Update movie export code to work with latest version of FFmpeg.
1399 + Make "Show Log" a toggle, so you can click on the button to take a look at
1400 the log, and a second click returns you to the survey view.
1402 + (Microsoft Windows version): Open the font file in binary mode - it looks
1403 like we were lucky and the font file (or at least its current version)
1404 would have loaded OK in text mode despite being binary data.
1406 + (Microsoft Windows version): Exporting to files with non-ASCII filenames
1411 + Allow tape or backtape to be omitted. Reported by Erin Lynch.
1413 + Grid convergence is now corrected for when using automatically
1414 calculated declinations (*declination auto <X> <Y> <Z>). Requested
1415 by Mateusz Golicz on the mailing list.
1417 + Clear any cached calculated declination upon another *declination auto
1418 with different coordinates. Previously if the date stayed the same,
1419 a previously cached declination for the old coordinates was used.
1421 + Fix check for end of version number array in *require. We would check up
1422 to 12 version components, the last 9 being bogus. In practice, *require is
1423 only likely to be used with up to three components, so this wouldn't be an
1426 + *begin with an invalid prefix could cause a crash in some cases. Fixed
1427 by patch from Colin Watson.
1429 + Report column locations for errors to do with readings.
1431 * Merge translation updates from Jean-Marc.
1433 * img library: Better document which members can be set when writing.
1434 Highlighted by email query about use of img API from Владимир Георгиев.
1436 * Document how *declination interacts with *calibrate declination if both are
1437 used in the same dataset.
1439 * doc/3dformat.htm: Update details of how changes to the current label buffer
1440 are encoded to reflect changes in v8. Reported by Angus Sawyer.
1442 * Use docbook2man instead of docbook-to-man to generated Unix man pages
1443 from SGML source. The latter seems to be no longer actively maintained, and
1444 docbook2man now does a similarly good job.
1446 * Use https for survex.com links, and for other sites which support it.
1448 Changes in 1.2.26 (2016-01-07):
1452 + (Microsoft Windows version): Fix to be able to process .svx files with
1455 * (Microsoft Windows version): Simplify upgrading process with innosetup
1456 installer - if Survex is already installed, we now just install to the same
1457 location and use the same start menu folder.
1459 * (Linux version): survex.spec: Update for filetype metadata change in 1.2.25.
1460 Fixes #79, reported by James Begley.
1462 * (Linux version): survex.spec: Fix to work with RPM 4.13. Fixes #79, reported
1465 Changes in 1.2.25 (2016-01-05):
1469 + Drop broken code which attempts to fix 2D pitches. Fixes #73, reported by
1470 Erin Lynch. #76 tracks the issue the removed code was trying (but failing)
1473 + When animating, don't try to update station info based on mouse movement
1474 over the survey tree.
1476 + Further improve code to handle cavern subprocess in aven.
1478 + Fix jump to error for filenames containing colons when the error location
1479 doesn't have a column number. Bug noted by Jenny Black.
1481 + If we encounter bad UTF-8 in cavern output, replace it with a red and white
1482 ? in a diamond (previously we gave up showing output at the first bad
1483 sequence). This can happen if you process a .svx file which isn't UTF-8
1486 + (Unix version): Don't try to set the terminal window title when opening an
1487 editor from the cavern log window - gnome-terminal no longer supports this,
1488 and there doesn't seem to be a portable option for specifying the title for
1489 terminals which do still support this.
1491 + (Microsoft Windows version): Also quote for cmd.exe so that paths with
1492 spaces in work reliably. Reported by Marco Cotto.
1496 + Improve error for mismatched fore/back-sight plumbs, reported by Andy
1499 + Fix to use correct sd for backcompass. We were using zero instead, the
1500 most obvious effect of which was that the threshold for warning about
1501 differing COMPASS and BACKCOMPASS was about 71% of what it should have
1502 been, so we were warning in more cases than we should have been.
1504 + Implement support for specifying a length on backsights - if you're using
1505 something like a disto-x, you'll get a distance reading for the backsight
1506 too. Fixes #71, reported by Erin Lynch.
1508 + Make line counting more robust to mixed line ends. Noticed in example file
1509 from Pete Smart (see #69).
1511 * extend: New --show-breaks option which adds a leg flagged as surface survey
1512 between each points at which a loop has been broken. Suggested by Jenny
1515 * (Unix version): Update filetype metadata to work with modern desktops.
1517 * Fix incorrect reporting of errors reading and writing processed survey data.
1518 Since 1.2.8, the error strings corresponding to IMG_CANTOPENOUT,
1519 IMG_BADFORMAT and IMG_DIRECTORY have been mixed up (this doesn't affect
1520 external programs using the img library, only Survex). Reported by Jenny
1523 * Add missing options to extend man page and --help output. Noted by Jenny
1526 * Document Document Ctrl+cursor keys for rotating and tilting in aven man page.
1528 * Fix broken SGML markup in manual.
1530 * Fix typo in manual reported by Jenny Black.
1532 * Update vim syntax file for newer commands, etc.
1534 * Minor translation updates. Thanks to Piotr Strębski and Jean-Marc.
1536 * Fix to compile with FFmpeg 2.9. Reported by Andreas Cadhalpun in
1537 https://bugs.debian.org/803863
1539 * Stop maintaining ChangeLog files. They make merging patches harder, and stop
1540 'git cherry-pick' from working as it should. The git repo history should be
1541 sufficient for complying with GPLv2 2(a).
1543 * (Microsoft Windows version): The installer requires admin privileges on Vista
1544 and later and OS versions older than Vista are past end of life, so drop code
1545 which tries to set up the registry differently depending if we have admin
1548 Changes in 1.2.24 (2015-09-23):
1552 + (Microsoft Windows version): Fix the cavern log window. Reported by Brian
1555 + (Microsoft Windows version): Add workaround to avoid breakage in Therion.
1556 Reported by Jenny Black.
1558 + If wx was built with thread support, aven now runs cavern from a separate
1559 thread, which works much better under wxMSW (where we can't use select),
1560 and also seems a bit smoother on Linux.
1562 + Fix handling of encoding of filenames when the operating system has no
1563 locale installed corresponding to the language selected for Survex's
1566 + Undo accidentally committed debugging code which was sending message to
1567 the terminal in 1.2.23.
1569 * (Linux version): configure now looks first for wx-config-3.0, which Fedora's
1570 wx3 packages have. Reported by James Begley.
1572 * Indonesian translation fully up to date again.
1574 * Manual: Document anonymous stations, based on the text from NEWS. Reported
1577 Changes in 1.2.23 (2015-09-06):
1581 + Updating the cavern log window is now much smoother, especially on slower
1584 + Show "busy" mouse cursor while processing survey data.
1586 + Fix an assertion if you try to start processing a survex file while one is
1587 already being processed.
1589 + Processing a .svx file with an error now still adds it to the file history.
1590 Reported by Martin Green.
1592 + Fix the orientation of the starting end of tubes.
1596 + New *ref command to allow specifying an external reference (e.g. where to
1597 find the original survey notes).
1599 + Drop support for showing percentage progress in cavern. It's confusing in
1600 a multiple-file dataset as it shows progress in the current file so jumps
1601 around. It also slows down processing, and on a slow machine you'd don't
1602 want that, while on a fast machine processing isn't slow enough for the
1603 progress display to be useful.
1605 * French translation is now completely up to date, thanks to Michel Bovey.
1607 * Bundle proj's EPSG and ESRI code lists in the installers for MS Windows and
1608 OS X so that things like "*cs EPSG:29903" work. Reported by Graham Mullan.
1610 * (Microsoft Windows version): Process survey data with aven rather than
1613 * (Microsoft Windows version): Installer built with InnoSetup 5.5.6 (recent
1614 releases have been built with 5.5.3) to see if that solves Ray Duffy's
1615 reported issue with not having file associations for .svx files created.
1617 Changes in 1.2.22 (2015-08-17):
1621 + Ensure that the window has a depth buffer. Whether it does by default
1622 seems to vary depending on OS and maybe graphics card. Fixes #55 (terrain
1623 is no longer visible through itself), and also the rendering of passage
1624 tubes. Thanks to Martin Green for pointing me in the right direction for
1629 + Fix *declination with an angle to actually work.
1631 + Fix assertion if we try to identify a hanging survey by an anonymous
1634 + Improve errors for invalid survey names in *begin, *end, *equate and
1637 Changes in 1.2.21 (2015-07-28):
1641 + Fix exporting to KML and other text-based formats to always use "." for the
1642 decimal separator - previously "," would be used when the user's locale
1643 specified this for the decimal separator. Reported by Jan Schorn.
1645 + Implement exporting of survey legs in KML format.
1647 + Put "paddle" placemarker icons on stations in exported KML files, using the
1648 same colour coding for entrances, fixed points and exported points as aven
1651 + Remove the "Coordinate projection" field from the print dialog, as it isn't
1652 relevant there. Reported by Wookey.
1654 + Fix the initial scale for small caves (since 1.2.18 the initial scale has
1655 been too small). Reported by Wookey.
1657 + Don't rescale if the same file is reloaded, but adjust the volume diameter
1660 + Use wxGetenv() to read the SURVEXEDITOR variable, so we can accept Unicode
1665 + Fix coordinate systems using latitude and longitude - PROJ.4 wants these in
1666 radians, but we were passing degrees, which would generally cause the
1667 conversion to the output coordinate system to fail. Reported by Wookey.
1669 + Fix *fix with standard deviations when *cs is in use, give an error for use
1670 of *fix with standard deviations before *cs.
1672 + Add new *declination command with support for setting the declination
1673 automatically from the IGRF model based on the survey date. Thanks to the
1674 Therion developers for the IGRF support code, which we're reusing.
1675 Fixes #54, reported by Wookey.
1677 + Allow the units for the zero error to be specified, making it easier to
1678 specify calibration with a scale if you measure the zero error externally
1679 (rather than using the instrument itself). Fixes #61, reported by Andrew
1682 + Report the error from PROJ when coordinate conversion fails as part of the
1683 actual error rather than on a separate line.
1685 + Fix use after free after *solve. This only occurs if a leg between the two
1686 exact same stations appears right before and right after the *solve, which
1687 is unlikely in real data, but the testsuite has an instance of this. This
1688 was introduced by the repeat leg averaging added in 1.2.17.
1690 + Fix small memory leak when solving network. This doesn't really matter
1691 when solving at the end of processing as cavern will exit after that, but
1692 if *solve is used we continue processing after solving.
1694 * Remove compatibility handling for specifying a country variant of a language
1695 in SURVEXLANG using "-" with a lower case country code (e.g. "en-us") - we
1696 changed to the standard "en_US" way back in 2001. This code was mangling
1697 character sets with a "-" in, and is no longer useful.
1699 * Ignore any "@<something>" modifier in the language code.
1701 * Improve documentation of magnetic declination handling, and cover the new
1702 "*DECLINATION" command.
1704 * Document aven's command line options in the manual and its man page.
1705 Reported by Jenny Black.
1707 * Point to '*case' and '*truncate' from the 'SEE ALSO' sections of each other's
1710 * Remove references to SpeleoGen from the documentation - it hasn't been
1711 updated for many years, and can't read recent versions of the .3d format.
1713 * Strip documentation references to obsolete versions of MS Windows.
1715 * doc/HACKING.htm: Update list of debian packages to install to build from git.
1717 Changes in 1.2.20 (2015-06-26):
1721 + When printing, use the top margin rather than the right margin to calculate
1722 the height of the printable area. In practice, the two values seem to be
1723 the same or very similar by default.
1725 + Avoid assertion if the about dialog image fails to load. Reported by Phil
1728 + Optimise the size of the about dialog images.
1730 + Add support for reading terrain data which isn't in a .zip file.
1732 + Force a refresh after loading terrain data so that it gets displayed right
1735 + Make checks for terrain data extensions in zip files case insensitive.
1737 + If reading terrain data fails, always report an error and never try to
1740 * cavern: Allow clino readings in diving style data, suggested by Andrew
1741 Atkinson. Currently these readings are ignored, but a future version will
1742 check that they're consistent with the angle given by the depth gauge and
1743 tape, and perform suitable averaging.
1745 * Remove lingering traces of svxedit.
1747 * configure: Fix to allow compiling without libav/ffmpeg, as was possible
1750 * (Unix version): Install the filetype and aven application icons under
1751 /usr/share/icons/hicolor, which is where they're expected to be these days.
1753 * (Unix version): Add %f to Exec in survex-aven.desktop.
1755 * (Mac OS X version): Remove useless extra copy of about box images from OS X
1758 * (Mac OS X version): Only ship one copy of each of the translations.
1760 * (Mac OS X version): Reduce the size of the aven binary by disabling a load of
1761 libav features we don't use.
1763 * (Microsoft Windows version): Reduce the size of the aven binary by disabling
1764 a load of libav features we don't use.
1766 * (Microsoft Windows version): Update message files to fix a missing Chinese
1767 message in the installer.
1769 Changes in 1.2.19 (2015-06-18):
1773 + Fix exporting to GPX, KML and HPGL, which all failed to write the header to
1774 the exported file in 1.2.18.
1776 + Add exporting to Survex .pos format.
1778 + If the measuring line isn't currently active, pressing "Escape" will now
1779 exit full screen mode.
1781 + (Mac OS X version): Change the shortcut for full screen mode to be the
1782 standard Ctrl+Command+F (rather than Shift+Command+F which we have been
1785 + (Mac OS X version): When we centre the view on the station this can
1786 generate a mouse move event, so clear the variable which says we are
1787 dragging before we process a left click on a station. This avoids random
1788 rotations of the survey when clicking on a station, reported in #47 by Hugh
1791 + (Mac OS X version): Force use of a non-native toolbar to stop the toolbar
1792 icons from being rescaled and looking fuzzy.
1794 + (Mac OS X version): Remove code added in 1.2.18 which tries to set stop the
1795 toolbar icons from being rescaled, but which requires an unreleased version
1796 of wxWidgets, had a typo in, and doesn't actually seem to work anyway.
1798 + (Mac OS X version): Drop out of full screen mode if the mouse is mode to
1799 the top of the screen, since we can't seem to display the menu bar in this
1800 case like we do on other platforms.
1802 + (Mac OS X version): Enable aven's movie export feature.
1804 + (Mac OS X version): Enable wxDisplay when building wxWidgets to better
1805 support multi-monitor setups.
1807 + (Mac OS X version): Silence warning visible when aven is run from a
1808 terminal about a missing CFBundleTypeRole.
1810 + When reading terrain data from a .zip file, report an error if the .zip
1811 file is bad, or if it doesn't contain any terrain data we recognise.
1813 + Tweak error message in terrain reading code to distinguish two failure
1816 + Add viewing angles and scale to footer, and shorten some of the other items
1817 to make room for this extra information. (Fixes ticket #52, reported by
1820 + If the footer is wider than the printout width, scale down the font used
1821 so that it exactly fits; if the footer is narrower, than space out the
1822 items in in so it uses the full width.
1824 + If the saved size for aven's window exceeds the current display size
1825 (mostly likely because we're now plugged into a smaller monitor), then
1826 reduce the size of the window to fit the display. If the saved size is <
1827 (480x320), increase it to at least that, as aven isn't usable in a smaller
1830 + Remove crude bodge which tries to pick a nicer initial window size when
1831 using wxWidgets without wxDisplay on a multi-monitor setup - aven now opens
1832 with the same size window it had when it was closed, so the initial size is
1833 only relevant on the first ever run.
1835 * Assorted translation updates. Notably Indonesian is at 100% again.
1837 * Stop trying to catch and report signals. The only real reason to do it is so
1838 we can say "Bug in program detected! Please report this to the authors"
1839 before we exit, but when the program crashes that's pretty obvious. In aven
1840 we try to pop up a message box for this message, which may fail due to
1841 whatever caused the signal, while with the command line tools there's no
1842 great benefit over just letting the shell report the signal.
1844 * Use pkg-config to probe for libav and proj, which sorts out the correct flags
1845 for building on OS X against a static install of libav.
1847 Changes in 1.2.18 (2015-06-03):
1851 + Add support for reading terrain data (from a zip file containing either an
1852 SRTM .hgt file, or an ESRI .bil file and associated metadata files), and
1853 rendering it as a transparent surface.
1855 + Remove actions from 'Orientation' and 'Rotation' menus which you wouldn't
1856 sanely want to perform from the menu.
1858 + Create a "Colour by" submenu of the "View" menu to house the various
1861 + Add "Colour by Gradient" and "Colour by Length".
1863 + Make the button to dismiss the "About" dialog "OK" rather than "Close",
1864 which seems more logical, and also allows the dialog to be closed by
1867 + Destroy any existing clipping region before we write the page footer.
1868 Hopefully solves ticket #52, reported by Erin Lynch.
1870 + Don't round bearing and tilt angles to integers when printing and
1873 + Add passage export for EPS format. (Partly addresses ticket #4)
1875 + Add JSON export. This should be regarded as experimental, and the format
1876 is quite likely to change.
1878 + Pressing F6 now toggles the display of rendering stats, currently FPS
1879 (Frames Per Second) and the number of triangles in the terrain mesh.
1881 + Add a menu item and toolbar button to show the cavern log window if the
1882 currently shown survey data was processed by aven. Reported by Hugh St
1883 Lawrence in #47, and by Dave Clucas and others previously on the list.
1885 + Add "Save Log" button to Aven's cavern log window.
1887 + In cavern log window, highlight "error" markers in red and "warning"
1890 + Rework code to read cavern's output. In particular, we no longer mix
1891 buffered and non-buffered system calls.
1893 + Aven's support for reading colours and font sizes for printouts from
1894 print.ini has never worked - the contents of the ini files are ignored due
1895 to a bug which has been there since the code was added in 2005 - but nobody
1896 has ever complained. So just strip out that code entirely - we should
1897 support setting the colours and font sizes, but a GUI interface for setting
1898 them would be better.
1900 + Fix to compile with a Unicode build of wxWidgets 2.8. Reported by Bill
1903 + Take the width of the messages used above the compass and clino into
1904 account when calculating how much space to allow for them - now the labels
1905 won't overlap or be cut off in translations where they are long.
1907 + (Mac OS X version): Attempt to address the size of the toolbar icons.
1911 + Reject *fix with SDs which aren't all positive. (fixes#2, reported by
1914 + Use the currently set units when outputting measurements in warnings,
1915 errors, and the stats at the end of the run. Requested by Bill Gee.
1917 + Include column number when a *include file isn't found.
1919 + Show 'error' in front of error messages, like we show 'warning' in front of
1920 warnings. Fixes #48, reported by Wookey.
1922 + Increase the threshold for warning that fore and back measurements differ
1923 from 2 SDs to 3 SDs.
1925 * findentrances: If the 3d file specifies the coordinate system, use it.
1927 * svxedit: Remove svxedit - while an editor with built-in knowledge of survex
1928 would be nice to have, svxedit doesn't really offer that, and it looks ugly
1929 in a modern desktop.
1931 * If we run out of memory while reading a processed survey data file, include
1932 the filename in the error message.
1934 * Many translation updates - notably Indonesian and Russian are now the two
1935 most complete translations.
1937 * (Microsoft Windows version): Add code page 1252 mappings for fancy quotes.
1939 * Transliterate gradient and infinity symbols if the current character set
1942 * Add SVG version of .plt icon.
1946 + Add complete list of quantities you can set SDs for. Thanks for Wookey for
1947 highlighting that the previous list was incomplete.
1949 + Document averaging of a group of repeated readings.
1951 + Add a link to the sample data from the manual.
1953 + Remove references to contact addresses which are no longer there. Remove
1954 offer to post people floppies, and references to a CD image which isn't
1955 available for download.
1957 * Remove non-breaking spaces from the diffpos and extend manual pages, as they
1958 actually make the output formatting worse (presumably these used to work
1959 around a since-fixed bug in one of the docbook processing tools).
1961 * doc/TODO.htm: Update.
1963 * Fix to compile without warnings with 'g++ --std=gnu++11'.
1965 Changes in 1.2.17 (2015-02-24):
1969 + Update INSTALL file with current status.
1971 + Aven.app now has a custom icon.
1973 + Add icons for all the filetypes supported.
1975 + Add Finder actions for .svx, .3d, .plt and .pos files.
1977 + aven: Hide the status bar and tool bar in Full Screen mode, as wx doesn't
1978 currently do this for us.
1980 + aven: Fix short-cut for toggling Full Screen mode.
1982 + aven: Make "About" menu item appear.
1984 + aven: Fix "Close" button in about dialog.
1986 + aven: Make custom cursors black with a white outline to match the standard
1989 + svxedit: Now wrapped up in an application bundle as svxedit.app. It
1990 still doesn't really work like a standard app though - e.g. you can't load
1991 files from Finder (instead run svxedit.app and use File->Open), the font
1992 size of most menu items is wrong, the icon for the app is the wish icon
1993 rather than the svxedit icon, shortcuts use Ctrl not the Cmd key, and
1994 probably more. I'd probably recommend using another editor (OS X comes
1995 with TextEdit.app for example).
1997 + The documentation is now in a "Docs" directory alongside the apps, rather
1998 than in the rather less obvious "share/doc/survex" directory.
2000 + Default to building for x86_64, since all modern Macs are 64 bit.
2002 + Disable use of liblzma when building wxWidgets for OS X, which was
2003 preventing the build from working on OS X 10.6.8.
2005 + Download wx sources from SF via redirecting link. Thanks to David A.
2008 + buildmacosx.sh: Handle the mount point for the disk image containing a
2011 + Link with a static build of PROJ for doing coordinate system conversions.
2013 + Build wx with --disable-webview to avoid a compilation failure on OS X
2016 + Use wx-config --cc and --cxx to get the compilers to use for building
2017 everything else, as wx adds options to them which otherwise cause linking
2020 + The diskimage (.dmg) file is now compressed with bzip2, which gives a
2021 smaller download. This means OS X 10.4 is required, but we probably
2022 already need at least 10.5 because that's the minimum version which the
2023 wxWidgets build supports by default.
2025 + Remove unused files and copies of files from the diskimage.
2027 * cavern: If the same leg is repeated consecutively, average the readings and
2028 treat as a single leg.
2030 * dump3d: Report SEPARATOR used by the file being read.
2032 * aven.svg: Fix visual glitch in SVG icon for aven. Noted by David A. Riggs.
2036 + Greatly reduce flicker when mouse is moved to the top of the screen in full
2037 screen mode and the menu bar reappears.
2039 + For export formats where scaling is supporting, aven now actually uses the
2040 scale specified in the export dialog (previously it ignored this and used
2043 + Reimplement animation so that it's based on angular change per unit of
2044 elapsed time, rather than averaging the time take for the last two scene
2045 redraws. This gives smoother animation in the face of variable load and
2046 scene redraw time, and should be more consistent between platforms.
2048 + Switching to a point of the compass during auto-rotation now jumps straight
2049 there rather than the two animations fighting.
2051 + Reduce the maximum auto-rotation speed, as the previous limit was uselessly
2054 + Disable stepping the rotation angle when animating (previously we only did
2057 + Speed up start-up a bit - rather than loading icons from individual PNG
2058 files on disk, compile them into the aven binary.
2060 * (Unix version): Add "MimeType" field to desktop files so that file
2061 associations work out of the box with modern desktop environments.
2063 * Add start of Hungarian translation from Imre Balogh.
2065 * Merge in many updates to the Russian translation from "vsuhachev".
2067 * Assorted minor updates to other translations.
2069 * Create scalable (SVG) versions of file type icons.
2071 * doc/manual.sgml: Remove $Id and $Date markers, as they don't get expanded now
2074 * tests/: Improve test coverage in a few places:
2076 + Extend tests of fore and back sights to test calibration of the back
2079 + Test "Can't calibrate angular and length quantities together" error.
2081 + Check that "*set names ." works when "." is also the decimal point.
2083 Changes in 1.2.16 (2014-10-17):
2085 * aven: Add KML export (stations only currently).
2087 * aven: Allow measuring line to measure from anonymous stations. (Fixes #44)
2089 * aven: Fix corrupted names in exported files.
2091 * aven: Fix error log window under wxWidgets >= 2.9 to include the system
2092 information before the first log message like it does under wxWidgets 2.8.
2094 * cavern: Add support for "*cs JTSK" and "*cs JTSK03".
2096 * tests/: Improve test coverage.
2098 * Translation updates for many languages, plus the start of translations to
2101 * Fix to build against wxWidgets 3.0 built with assertions disabled. Reported
2104 * Fix warnings when compiling with clang (which is the default compiler on
2105 Mac OS X). Reported by Martin Sluka.
2107 Changes in 1.2.15 (2014-08-14):
2109 * cavern: The *cs command now also supports "long-lat", "s-merc" (for "Web
2110 Mercator"), EPSG and ESRI codes, "eur79z30", "ijtsk" and "ijtsk03". This
2111 means that we now support all the coordinates systems which Therion does,
2112 except for a few which don't have X=East and Y=North. The documentation
2113 for *cs has also been improved.
2115 * aven: We no longer persist full screen mode between runs - it's not a
2116 standard behaviour of desktop programs, and it's too easy to go into full
2117 screen mode from the menu and then not be able to get out again because you
2118 don't know the required key shortcut. (ticket#39)
2120 * aven: When in full screen mode, moving the mouse to the top of the screen now
2121 makes the menu bar appear. This provides a non-shortcut way out of full
2122 screen mode, as well as making it easier to perform other operations while in
2123 full screen mode. The current implementation gives an annoyingly flickery
2124 transition, but hopefully we can improve this in future. (ticket#39)
2126 * (MacOS X version): If built with wxWidgets >= 3.1.0 (which is still in
2127 development), we now call EnableFullScreenView() which improves the full
2128 screen mode experience on OS X 10.7 and later.
2130 * img library: Improve documentation for img_ERROR_INFO.
2132 * tests/: Ship some missing .out files and compare.tst.
2134 * tests/: cavern.tst testcase back2 is now actually used. Fix a bug in this
2135 testcase, and extend it to cover a variant of the situation reported as a bug
2136 in therion by Bill Gee to the therion list.
2138 * (Linux version) survex.spec: Add run-time requirement on proj and proj-epsg
2139 for the survex package and on tk for the svxedit package.
2141 Changes in 1.2.14 (2014-07-05):
2143 * img library: Add ability to store a PROJ4 string describing the coordinate
2144 system in use in 3d v8 files.
2146 * aven: If the 3d file specifies a coordinate system, then use it for exporting
2147 to formats which need to know (currently GPX). If the input file doesn't
2148 specify the coordinate system, allow the user to enter a PROJ4 string in the
2151 * aven: You can now quickly zoom to a particular area by holding down the
2152 "Shift" key and dragging with the left mouse button to create a rectangular
2153 "rubber band box" around the area you wish to zoom to. If you release the
2154 "Shift" key while still dragging, the box is centred on the start point
2155 rather than having one corner there.
2157 * aven: Fix exporting of passage tubes in elevations and extended elevations
2158 - previously up and down were getting drawn across the page!
2160 * aven: Fix "Cancel" to work on the print/export dialog, broken by changes in
2161 1.2.13. (Reported by Brian Clipstone)
2163 * aven: Fix the conditions on which the menu item "Cancel measuring line" is
2164 enabled - previously it was hard to actually cancel it via the menu.
2165 Reported by Hugh St Lawrence.
2167 * aven: Fix wx assertion failures when showing hit test debug view on platforms
2168 such as 64-bit Linux.
2170 * aven: When viewing from above, show "Plan" above the "clino" which indicates
2171 the tilt angle (instead of "Elevation -90°").
2173 * aven: The extended font data now loads faster, and also uses less memory on
2176 * aven: Dragging the vertical divider between the side panel and the 3D view
2177 now only updates when you finish the drag, as redrawing continuously just
2178 looks clunky except on an ultra-fast machine.
2180 * aven: (German translation) Abbreviate "Blickrichtung" so it doesn't overfill
2181 the space available in the aven UI.
2183 * cavern: Add a *cs command to allow setting the coordinate system for *fix
2184 commands, and the coordinate system used for processed survey data. The
2185 latter is now stored in 3d v8 format files.
2187 * cavern: Add support for 'L' flag (exclude from length) in Compass .dat files
2188 and handle it in the same way as the "DUPLICATE" flag in .svx files.
2190 * cavern: If there's more than one *fix command with coordinates, still
2191 actually fix the second and subsequent ones, to avoid triggering bogus errors
2192 about unconnected surveys.
2194 * cavern: If there's more than one *fix command with coordinates, report the
2195 station name of the previous one, plus the file and line number where it was.
2197 * cavern: Fix handling of the rather contrived case of *fix with no coordinates
2198 followed by *solve and then another *fix with no coordinates not to access
2201 * dump3d: Report any specified coordinate system.
2203 * doc/3dformat.htm: Update to document how the coordinate system is stored.
2205 * (Microsoft Windows version): Include dump3d in the installer.
2207 * Fix a compiler warning.
2209 * Improve test coverage.
2211 Changes in 1.2.13 (2014-05-15):
2213 * aven: Fix --print option to wait for printing to happen before exiting
2214 (previously it would exit right after opening the print dialog, so you
2215 couldn't actually print anything out using it).
2217 * aven: Increase the threshold for how close the pointer needs to be to a
2218 station from 5 pixels to 7 to try to help touchscreen users. Reported by
2221 * aven: Add "fat finger" mode, toggled by pressing F2, to allow investigating
2222 if increasing the minimum pointer to station threshold helps Hugh's problems
2223 with using aven on a touch screen device.
2225 * aven: The measuring line was unable to see stations which had just been
2226 revealed by toggling surface or underground legs on - this is now fixed.
2228 * aven: Add "hit test grid debug" mode, which shows the hit test grid and how
2229 many entries are in each box (toggled by F3).
2231 * aven: Pressing F4 now allows the user to toggle wxWidgets assertion messages
2234 * aven: Create the empty hit-test grid data structure lazily, to reduce start
2237 * cavern: Improve messages which talk about "tags" and/or "prefixes" in *begin
2238 and *end commands to instead talk about "survey names".
2240 * cavern: For ages cavern has warned if you reentered a survey, but this
2241 warning was suppressed if it occurred at the same line of the same file as
2242 the survey was first entered, but this can only happen if you include the
2243 same survey file more than once, which isn't a sensible thing to do for a
2244 file with actual survey data in (you might reasonably do it to set up survey
2245 grade details or something like that). The warning is now given in this
2248 * cavern: After 5 warnings about reentering a survey we give up warning about
2249 it, but we used to keep reporting where the survey was originally entered -
2250 this secondary diagnostic message is now silenced when the main message is.
2252 * (Microsoft Windows version): Compile C code with optimisation on.
2254 * Add the start of a Russian translation, with messages take from therion.
2256 * Minor translation updates to French.
2258 * Fix compiler warning from GCC.
2260 * Testsuite improvements:
2262 + Test that "..." anon station works.
2264 + cavern.tst: Check number of errors returned by all testcases which should
2265 fail and give an error count.
2267 + cavern.tst: Fix to actually fully test everything when builddir != srcdir.
2269 Changes in 1.2.12 (2014-04-14):
2271 * aven: Fix measuring line to show change in altitude rather than altitude
2272 itself (accidentally broken by changes in 1.2.11). Reported by Brian
2275 * aven: Fix printing when built with wxWidgets 3.0.
2277 * aven: Several visual improvements to printouts:
2279 + Move the numbers below the scale bar down a little so that they don't
2280 overlap the scale bar ticks.
2282 + Set the clipping region after we draw the page border and info box to avoid
2283 clipping the border in print preview.
2285 + Tidy up the appearance of the compass and elevation arrow.
2287 * aven: Fix to build with libav 10. Reported by Moritz Muehlenhoff in
2288 <http://bugs.debian.org/739332>.
2290 * aven: Fix to build with older libav where avcodec_free_frame() isn't
2293 * (Linux version) survex.spec: Update spec file used for building RPM packages.
2295 * (Unix version): Add "Keywords:" entry to .desktop files.
2297 * (Unix version): Enable large file support, mostly to support filing systems
2298 which return 64 bit inode values, such as CIFS mounts.
2300 * (Microsoft Windows version): Only allow "A-Z" or "a-z" for driver letters,
2301 rather than any character which is a letter in the current locale.
2303 * Various translation updates.
2305 Changes in 1.2.11 (2014-01-28):
2307 * aven: Fix wxWidgets assertion when double clicking on an anonymous station.
2308 Reported by Kevin Dixon.
2310 * aven: Embed the font data for the first 256 Unicode characters for use in the
2311 survey pane into the compiled aven binary to reduce start up overhead. Any
2312 additional characters needed are loaded from a data file only if/when a
2313 character >= U+100 is actually needed (as before).
2315 * aven: Fix display of Unicode characters above 256 when there's a character
2316 <= 256 earlier in the same string.
2318 * aven: Use the actual width of Unicode characters above 256 rather than
2319 assuming they are 16 pixels wide.
2321 * aven: If full screen, don't show the side panel when a new file is opened
2324 * aven: Don't give an assertion failure when showing passages for a cave with
2325 no vertical extent. Reported by Jonny Prouty.
2327 * aven: Change terminology in print dialog - say "legend" instead of "info
2330 * aven: Add option to show the tilt angle as a percentage gradient.
2332 * aven: Show the units (degrees, grads, or percent) for the tilt and bearing
2335 * aven: All length units are now translatable.
2337 * aven: Split log_fl_error helper function out of CHECK_GL_ERROR macro, which
2338 will reduce code size and also the number of deprecation warnings about
2339 gluErrorString on Mac OS X 10.9.
2341 * (Microsoft Windows version): aven: Try to work around redraw issues related
2342 to the measuring line by redrawing the whole window, which doesn't seem to be
2345 * cavern: If *units is used to try to set units for LEVEL, PLUMB, or POSITION,
2346 give an error rather than quietly ignoring the attempt.
2348 * cad3d: Make cad3d remap control characters and spaces in station names when
2349 generating PLT output in the same way aven does.
2351 * Various translation updates (particular thanks to Eric Madelaine and Dennis
2352 Baudys), including the start of a Bulgarian translation, with messages taken
2353 from Therion and elsewhere.
2355 * (Microsoft Windows version): On Microsoft Windows 2000 and newer, use
2356 GetUserDefaultUILanguage() to get the UI language to use. For older
2357 versions, continue to use GetUserDefaultLCID().
2359 * (Microsoft Windows version): The Indonesian translation will now be used
2360 automatically when the system language is set to Indonesian.
2362 * (Mac OS X version): Fix to build with wx 3.0.0 on OS X 10.9. Thanks to David
2363 A. Riggs for his work on this.
2365 * (Mac OS X version): Update buildmacosx.sh script to use wx 3.0.0, and add a
2366 checksum check for the downloaded wx sources.
2368 * Fix a lot of the compiler warnings when building with clang.
2370 * doc/manual.sgml: Add missing quantities to the list documented as accepted by
2371 *units: LEFT, RIGHT, UP/CEILING, DOWN/FLOOR (missing entirely);
2372 BACKCOMPASS/BACKBEARING, BACKCLINO/BACKGRADIENT (missing from the main list,
2373 mentioned in list of the units that can be set for them); COUNT (missing
2374 alternative name for COUNTER); DX/EASTING, DY/NORTHING, DZ/ALTITUDE
2375 (incorrectly listed as X, Y, Z). Reported by Jonny Prouty.
2377 * Test suite: Improve test coverage for cavern.
2379 Changes in 1.2.10 (2014-01-15):
2381 * aven: Fix assertion if two mouse buttons are held down at the same time.
2382 If dragging with more than one mouse button held down, releasing one causes
2383 another which is still held down to take effect. Reported by Brian
2386 * aven: If we fail to start the external editor when the user clicks on an
2387 error or warning from cavern, show an error box.
2389 * aven: If the survey has a title, add it as a top-level <title> element to
2392 * aven: Escape '<', '>', and '&' in labels in exported SVG files.
2394 * aven: In GPX export, set the <time> element to the datestamp from the 3d
2397 * aven: Don't try to write the title if it isn't set or is empty when exporting
2400 * aven: Don't bother looking up the printer page setup info when exporting.
2402 * (Microsoft Windows version): aven: Fix crash on "File->Print" or
2403 "File->Export" under Windows XP, reported by Brian Clipstone.
2405 * (Microsoft Windows version): aven: Fix error dialog about an incorrectly
2406 encoded filename which could occur if run without being asked to load a file
2409 * (Microsoft Windows version): aven: Compile with optimisation on.
2411 * img library, aven: Although processed CMAP data files are often referred to
2412 as "CMAP .XYZ files", it seems that actually, the extension .XYZ isn't used,
2413 rather .SHT (shot variant, produced by CMAP v16 and later), .UNA (unadjusted)
2414 and .ADJ (adjusted) extensions are. Since we've long checked for .XYZ, we
2415 continue to do so in case anyone is relying on it, but also check for the
2418 * img library: Add new "datestamp_numeric" field to struct img giving the
2419 datestamp as a time_t in UTC (or (time_t)-1 if there's no datestamp or we
2420 failed to convert it). For .3d >= v8, this field is reliable. We attempt to
2421 convert date strings in .3d <= v7 and CMAP XYZ files, but may get the
2424 * img library: Fix my_strcasecmp() to handle top-bit set characters better.
2426 * cavern: Fix NULL pointer dereference when processing Compass DAT file without
2429 * doc/manual.sgml: Update references to Survex 1.1 which should be to 1.2.
2431 * doc/manual.sgml: Note the station length limit Smaps used.
2433 * Fix some compiler warnings if built with glibc's fortify source feature
2436 Changes in 1.2.9 (2014-01-08):
2438 * Document --3d-version in cavern man page and the manual.
2440 * aven: Fix compilation error in movie export code with recent libavi.
2442 * aven: Fix warning on stderr when export a movie as MPEG.
2444 * img library: In non-hosted mode, don't define GETC and PUTC if they're
2445 already defined, to allow easy overriding with getc_unlocked() and
2446 putc_unlocked() (which are significantly faster on Linux).
2448 * img library: In non-hosted mode, check that int is at least 32 bits,
2449 and if not, use long. In practice, platforms with 16 bit int are mostly
2450 obsolete, but it's not hard to be portable here.
2452 * img library: Add test that img.c and img.h compile in non-hosted mode
2453 (regression test for issue fixed in 1.2.8).
2455 * (Microsoft Windows version): aven is now built with wxWidgets 3.0.0.
2457 * Update translations from launchpad and from existing similar messages.
2459 * Fix some compiler warnings.
2461 Changes in 1.2.8 (2013-10-29):
2463 * cavern: Fix handling of anonymous wall stations ('..' by default) to
2464 implicitly set the SPLAY leg flag, as was intended. Reported by Thomas
2467 * cavern: Tweak .err file output not to lose the space in front of certain
2468 statistics when the value gets large.
2470 * cavern: Eliminate redundant progress message when solving simultaneous
2473 * aven: Add a format drop down to the export dialog, and only show fields which
2474 are meaningful and supported for the currently selected export format. The
2475 format defaults to that used most recently. The "Elements" and "View" boxes
2476 have been swapped in the print and export dialogs as that layout works much
2477 better when the "View" box is hidden.
2479 * aven: Changing checkboxes in the print or export dialog didn't work in 1.2.7
2480 - now works again. Reported by Anthony Day.
2482 * aven: Add GPX export (based on findentrances patch from Olaf Kähler). In
2483 this release the projection which the survey coordinates are in defaults
2484 to the BMN M31 grid used in the Totes Gebirge in Austria. On Unix, you
2485 can edit ~/.aven and add a new line setting 'input_projection' to a PROJ
2486 projection string. The ability to specify this projection in a better
2489 * aven: New export options "Origin in centre" and "Full coordinates" - the
2490 latter fixes #10. GPX and PLT output implicitly force "full coordinates".
2492 * aven: The "Sketch" vector drawing program got renamed to "Skencil" some
2493 time ago, so update references.
2495 * aven: Make the Presentation->Play menu item a checkbox, to avoid a warning
2496 with wxMSW 2.9.5. Reported by Brian Clipstone.
2498 * aven: Make right click in an empty presentation mark the current position and
2499 open it to edit, instead of crashing.
2501 * aven: Update movie export code to work with latest libav API. Reported by
2504 * aven: Improve reporting of errors during the process of exporting a movie.
2506 * aven: Don't try to close the movie if we aren't producing one.
2508 * aven: Fix assertion failure when double-clicking on the survey with wx2.9.
2510 * aven: Fix to build with wxMSW 2.9.5.
2512 * aven: Fix to build with wx 2.9.5 with wx2.8 compatibility disabled.
2514 * cad3d: The "Sketch" vector drawing program got renamed to "Skencil" some time
2515 ago, so add a new --skencil option to specify this output format. The old
2516 name (--sketch) is still recognised for compatibility.
2518 * cad3d: Make --marker-size work for Skencil and SVG output.
2520 * dump3d: Make --show-dates option show dates for XSECT.
2524 + Fix to work once more when used outside of Survex (missing definition of
2525 max() macro and a bad call to free() in img_close() for a file opened for
2528 + Use lround() instead of round(), and make the tests around whether we use
2529 the library function or the our fallback implementation saner.
2531 + Fix // comments in C code for portability to pre-C99 compilers which don't
2532 support these as an extension.
2534 + Can now be compiled as C++ as well as as C.
2536 * (Microsoft Windows version): The installer is now built with a newer version
2537 of Innosetup, and includes translations for all the languages which Survex
2538 itself has any translations for.
2540 * (Microsoft Windows version): aven is now built with wxWidgets 2.9.5.
2542 * Minor translation updates.
2544 * tests/Makefile.am: Distribute files for "normal_bad" testcase.
2546 Changes in 1.2.7 (2013-07-27):
2548 * Add support for anonymous stations, which are indicated by one, two or three
2549 separator characters - with the default separator of '.', that means '.',
2550 '..', and '...' are anonymous stations. Single separator ('.' by default)
2551 is an anonymous non-wall point, double separator ('..' by default)
2552 is an anonymous wall point at the end of an implicit splay), and triple
2553 separator ('...' by default) is an anonymous point (with nothing special about
2554 the leg). A new *alias command allows '-' to be mapped to '..' for
2555 compatibility with pocket topo: *alias station - ..
2557 * New version 8 of the 3d format:
2559 + Supports new flags img_SFLAG_ANON and img_SFLAG_WALL.
2561 + New explicit file-wide flag for 'this is an extended elevation', rather
2562 than modifying the survey title to indicate this.
2564 + The survey prefix is often unchanged from one leg to the next, so use a
2565 spare flag to compactly indicate when there's no label change.
2567 + The data style of each leg is now stored.
2569 + The "processed at" time is stored as seconds since 1970 rather than a
2570 human-readable string.
2572 + Since 3d v8 features significant changes to the format, the format
2573 documentation for v7 and earlier has been split off into 3dformat-old.htm.
2577 + New station flags img_SFLAG_ANON and img_SFLAG_WALL.
2579 + Handle .pos files containing unnamed stations - don't suck the next line in
2580 as the station name, and set img_SFLAG_ANON for them.
2582 + Repurpose the long unused fBinary parameter to img_open_write() as a flags
2583 parameter, and add img_FFLAG_EXTENDED to specify that this is an extended
2584 elevation, in place of appending " (extended)" to the title. Internally we
2585 still append this to the title (and remove it upon reading) when writing
2586 3d v7 or earlier, but for the new 3d v8 format, this flag is stored
2587 explicitly in the file.
2589 + img.h: Add comments for the lists of "Leg flags" and "Station flags".
2593 + We now require at least wxWidgets 2.8.0 - it was released over 6 years ago
2594 now, and the wx developers consider even 2.8 to be rather long in the
2595 tooth. We stopped testing building with wxWidgets 2.6 some time ago, and
2596 formally dropping support for older versions allows a number of workarounds
2597 to be removed from the aven source code. Also, features deprecated in
2598 wxWidgets 2.9 are no longer used in our code.
2600 + Don't run incremental search on every key-press, as on a slow machine the
2601 short initial search(es) will take a while but not be useful. Instead only
2602 actually run the search when we're told there are no more key-presses
2605 + Implement support for including cross-section information in exported SVG
2606 and DXF files (ticket#4). The DXF export is untested currently.
2608 + Show splay legs faded by default, with menu options to hide them or show
2609 them like other legs.
2611 + Speed up loading a .3d file with cross-sections by using a map to convert
2612 station names to positions.
2614 + In the cavern log window, don't highlight a file:linenumber if there's no
2615 message after it, which avoids highlighting the "Included from" lines
2618 + Fix not to crash when trying to report an error while starting up.
2620 + (MacOS X version): Change the menu shortcut for "Full Screen Mode" to be
2621 the OS X standard shortcut Shift-Command-F (previously we used F11, but
2622 that's used by the desktop).
2624 + Add checks for errors when reading the font file.
2626 + Remove useless extra quoting when invoking vim to show the location of an
2629 + Include GL/gl.h before GL/glext.h (needed on Debian wheezy).
2631 + Use wxValidator to simplify keeping svxPrintDlg member variables and fields
2632 in the dialog in sync.
2636 + Demote errors about invalid dates to warnings, since we've accepted *date
2637 for ages without any checks on the value, and so existing datasets
2638 probably contain invalid dates and dates in other formats. (ticket#19)
2640 + New *alias command allows '-' to be mapped to '..' for compatibility with
2641 pocket topo: *alias station - ..
2643 + We want to warn if there's a clino reading which it would be impossible to
2644 have read from the instrument (e.g. on a -90 to 90 degree scale you can't
2645 read "93" (it's probably a typo e.g. for "39"). However, the gradient
2646 reading from a topofil is typically in the range 0 to 180, with 90 being
2647 horizontal. Really we should allow the valid range to be explicitly
2648 specified, but for now we infer it from the zero error - if this is within
2649 45 degrees of 90 then we assume the instrument can read between 0 and 180
2652 + If the survey isn't all connected, still run survey tree checks and report
2653 errors and/or warnings which might suggest typo locations. Thanks to Kevin
2654 Dixon for the report which highlighted this issue.
2656 + Report a warning if *begin SURVEY has a separator character in SURVEY.
2658 + Report column numbers as well as line numbers for some cavern errors and
2661 + Adjust width of node stats table to fit longest count when there are more
2662 than 9999 of a particular order of node.
2664 + If the argument to *include has an opening double quote but the closing
2665 double quote is missing, then skip trying to open the file.
2667 + Move "Station X referred to just once" warning after non-existent survey
2668 check - if both fire, the non-existent survey error is likely to be more
2671 + We no longer follow an error for a bad reading in passage data with a bogus
2672 "End of line not blank" error, but instead check the remaining readings on
2675 + We no longer follow an error about OMIT for a required reading with a bogus
2676 "End of line not blank" error.
2678 + Report an error if the scale factor in *calibrate is zero - it doesn't make
2679 sense and probably means someone reversed the arguments to *calibrate.
2681 + Report the parent include files starting from the outermost, as that's more
2682 logical when there are multiple levels involved.
2684 + If we were expecting a numeric field and instead get something which starts
2685 with '+', '-', or '.' but which isn't a number, then fix the error to
2686 include that character in the token reported.
2688 + Simplify handling of quantity lists to only recognise 'DEFAULT' as the
2691 * cad3d: Check for errors from img_rewind() and report them.
2695 + Build, install and package dump3d as standard - it's useful for grabbing
2696 info from 3d files in scripts.
2698 + Add --show-dates option.
2700 + Show only 2 decimal places on coordinates and passage dimensions.
2702 + Report the data style of legs.
2704 + Report if the file is an extended elevation.
2706 + Report img_STOP as STOP rather than CODE_0xffffffff.
2710 + cavern.tst: Fix equatenosuchstn testcase (added in 1.2.6) to normalise the
2711 expected output so it passes reliably.
2713 + cavern.tst: Run diffpos <expected> <actual> so the reports of 'Added' and
2714 'Deleted' stations upon failure are the more natural way round.
2716 + Add more testcases, expand some existing testcases, and add expected output
2719 * (Microsoft Windows version): Use wx-config's --cc and --cxx flags to find the
2720 appropriate C and C++ compilers to use, and link mingw build statically to
2721 avoid needing the libgcc DLL (which newer GCC seems to have by default).
2723 * (Unix version): When determining the character set for command-line tools,
2724 check environmental variable LANG after LC_ALL and LC_CTYPE.
2726 * When determining the language, check environmental variable LC_ALL before
2727 LC_MESSAGES and LANG (but after SURVEXLANG).
2729 * If we don't find the message file, only give an error if it was specified
2730 with SURVEXLANG, since that is an explicit instruction to Survex, whereas
2731 LANG, LC_ALL and LC_MESSAGES are essentially system "preferred locale"
2734 * There are a handful of hard-coded English message strings for reporting
2735 errors trying loading message files, etc. These are all now ASCII, as if we
2736 fail trying to open a message file, it's more likely the encoding isn't
2739 * Prune strings we are no longer using and are probably unlikely to use again
2740 into a new file po_codes_dead, so that translators don't get presented with
2743 * Merge lots of translation updates. Most translations are now complete or
2746 * Add start of Indonesian translation from Arief Setiadi Wibowo.
2748 * Fix various compiler warnings when building from source.
2750 * Include scripts gdtconvert and gen_img2aven in the source distribution.
2752 Changes in 1.2.6 (2012-02-23):
2754 * (Mac OS X version): Fix so that cavern finds its messages when run by aven.
2756 * (Microsoft Windows version): Include JPEG images for aven in the installer
2757 package (ticket#35).
2759 * cavern: If we have a reference to a station in a non-existent survey, give a
2760 helpful error rather than saying the station hasn't been exported from the
2761 survey. (Bug reported by Martin Green via email)
2763 * aven: Fix to build with a non-Unicode wxWidgets library. Patch from Olaf
2766 * findentrances: Add findentrances utility from Olaf Kahler which produces a
2767 .gpx file with waypoints for entrances. This needs libproj so is disabled
2768 by default for this release - to enable it install the development stuff for
2769 libproj and build survex with:
2771 make FINDENTRANCES=findentrances
2772 make install FINDENTRANCES=findentrances
2774 * dump3d: Add support for showing img_ERROR_INFO items.
2776 * doc/3dformat.htm: Merge in some improvements from Mike McCombe.
2778 * Incorporate a French translation from launchpad I'd previously copied the
2779 English version of by mistake. Attempt to correct mistranslation of "survey
2782 Changes in 1.2.5 (2012-01-03):
2786 + The survey tree in the left panel is now in sorted order once more.
2788 + No longer fails with an assertion if used for a long time (we were leaking
2789 an OpenGL list each time one had to be regenerated).
2791 + Now builds with newer FFmpeg library.
2793 + Draw measuring line in front of the indicators rather than behind them.
2795 + Loading a new file (or reloading the current one) no longer invalidates
2796 the OpenGL lists for the compass and clino, so will be a fraction faster.
2798 * Improve handling of attempts to look up translated messages before the
2799 message subsystem is fully initialised (which only happens if there's an
2802 * Improve the survex(7) man page text, and fix it to be marked as section 7 in
2803 the man page source as well as in the filename.
2805 Changes in 1.2.4 (2012-01-01):
2809 + A change in 1.2.3 meant that aven tried to use OpenGL before it was
2810 initialised, which doesn't cause problems in some machines, but causes aven
2811 to abort on others. This is now fixed, and there's a check in place to
2812 help avoid similar issues in future. (ticket#34)
2814 + Always use metres or feet for the depth colour key, and chose a consistent
2815 precision by looking at the depth range. (ticket#30)
2817 + Show the depth units below the colour bar rather than after every value.
2819 + When zooming way in, stay in metres rather than switching to cm.
2821 + On the scale bar, say “1 mile” rather than “1 miles”.
2823 * Translation updates for Catalan, French and Slovak.
2825 Changes in 1.2.3 (2011-12-31):
2827 * Fix to build with wxWidgets 2.9.2.
2829 * (Mac OS X version):
2831 + Processing .svx files from aven now works.
2833 + Remove spurious blank lines from the licence text in "Get Info".
2835 + Don't create the help menu at all, as it is empty (because the "About"
2836 entry goes elsewhere) and sometimes seems to appear in the UI.
2838 + INSTALL.OSX: Update to reflect current status.
2842 + Fix Y coordinates of surface surveys on printouts. (Closes #32)
2844 + Improvements to text plotted on the survey pane:
2846 - Support plotting Unicode character points > 256 by lazily loading the
2847 data for them from the font file and plotting them with a direct call to
2848 glBitmap(), which is slower but doesn't require a display list per
2851 - Adjust the spacing from fixed width to putting a one pixel gap either
2852 side of each one character (so two between adjacent glyphs). Mostly this
2853 reduces the horizontal width, but it adds a pixel for characters like "m"
2854 and two in a few cases.
2856 - Fix .pixelfont file generation to correctly handle characters wider than
2859 + Fix expected cross shape so don't always reject using texture mapping to
2862 + As we read a survey file, eliminate tubes consisting of zero XSECTs as well
2863 as those consisting of just one. Previously we would trip over the empty
2864 tube later. Such tubes can for example be created by extend if a splay shot
2865 is the start or end of a tube.
2867 + Make the green colour used for entrances in the survey tree the same
2868 (slightly darker than before) green used for the entrance blobs.
2870 + Report the version of the library we're actually running with if built
2871 against wx >= 2.9.2. Make it clear that the version reported is the
2872 version *built* with for wx < 2.9.2.
2876 + Copy the end markers for passage tubes.
2878 + Preserve left and right data for tubes (previously they were set to -1.0
2879 which means "no info").
2881 * img library: Fix incorrect comment in img.h which claimed that img_XFLAG_END
2882 was no longer used - it certainly is!
2884 * Use curly double quotes instead of "`" and "'" to quote filenames, etc in
2885 messages, and curly single right quote instead of straight ASCII apostrophe.
2886 Fall back to using straight ASCII versions if we can't represent them in the
2887 current character set.
2889 * Translation updates for Catalan, French, Slovak and Spanish.
2893 + Add test coverage for interleaved diving data.
2895 + Add testcase for diving data with topofil-style distance.
2897 Changes in 1.2.2 (2011-10-06):
2901 + Replace the textured-mapped font drawing with an approach based on
2902 glBitmap. This doesn't suffer from the character alignment issues which
2903 the textured-mapped fonts had, and is actually significantly faster on some
2904 machines. The current font used is (mostly) fixed-width, but this isn't an
2905 inherent limitation - it was just the easiest font data to convert to a
2908 + Fix assertion failure due to rounding differences on loading certain .3d
2911 + Fix assertion failure when turning on 3D passages if they stick out higher
2912 or lower than any station. (ticket#29)
2914 + Fix grid not to disappear when blobs are turned on and blobs are drawn
2917 + If a degree sign isn't available in the character set in use, transliterate
2918 it to 'dg' rather than skipping it.
2920 + Fix message which should have been a degree sign but got lost in the format
2921 change for 1.2.0 and then got reassigned in 1.2.1. Externally, this means
2922 that bearings in the status bar now have a degree sign after them if they
2923 are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
2925 + Fix print dialog to calculate the scale required for "One page" right
2926 before it calculates how many pages are required, so we don't end up
2927 something other than 1x1 being shown when the user changes settings.
2929 + Update the calculations for picking a scale and for deciding how many
2930 pages are needed to take into account the change in info box height made
2933 Changes in 1.2.1 (2011-10-04):
2935 * Translation updates for US English.
2939 + Rename the "depth bar" to "colour key" in documentation, menus, etc since
2940 it now shows colours for dates and errors as well as depths.
2942 + In the colour key for "colour by date", change "No info" to "Undated".
2944 + Remove the dark grey background from the colour key and just put a single
2945 pixel black border around the colours. This is more in keeping with the
2946 other controls, and means the colours are now on a black background so more
2947 visually similar to the survey legs.
2949 + Move the colour key's "Undated"/"Not in loop" entry down a little to
2950 improve the appearance. Make each section a pixel taller.
2952 + Allow "Colour by X" to be selected even if there's no data for X or only a
2953 single value of X used (the colour key is much smaller in these cases, and
2954 does still provide some useful information).
2956 + Fix incorrect calculation of depth colouring for survey legs which straddle
2957 a depth band boundary.
2959 + The scale bar, compass, clino, and colour key now all have right click
2960 menus which allow related actions to be performed (especially handy in
2963 + Improve the font used on the survey pane - it now contains the '-'
2964 character (so the clino now shows negative angles as negative, and dates
2965 in the colour key are now hyphenated). Also the spacing and alignment
2966 are a little better, though still not perfect.
2968 + PLT file export now handles spaces and control characters in station names
2969 by escaping them with '%' as in URLs.
2971 + Pressing "Enter" on a station in the tree control now centres the view on
2974 + The scale bar is now cached in an OpenGL display list since it often gets
2975 redrawn exactly the same - for example, when rotating, panning, etc.
2977 + Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
2978 then forces a refresh of the survey pane. This is intended as a debugging
2979 aid - if pressing F5 changes the display at all then there's a missing case
2980 where a list should have been invalidated (please report if you find such
2981 a case as it is a bug).
2983 + We now automatically track which OpenGL display lists need to be
2984 invalidated on window width or height changes.
2986 + Increase scale bar maximum width from 65% of the window width to 75% as it
2987 was in 1.0.x (except that if that would overlap the clino we now reduce
2988 that proportion down until it reaches 50%). Make the limit of zooming in
2989 the same as in 1.0.x. (ticket#23)
2991 + (Linux version): Previously wxGTK didn't really handle showing a dialog if
2992 the application was fullscreen (the dialog got opened under the main
2993 window!) To work around this, aven would switch out of full screen mode
2994 temporarily while showing a dialog. This case works properly with recent
2995 wxGTK, so disable our workaround with versions we know work. Also, apply
2996 the workaround only for wxGTK, not everywhere except on Microsoft Windows
2997 as there's no reason to think we need it for other platforms.
2999 + Grey out the "View North" action when we're already viewing North, and
3000 similarly for other compass points.
3002 + (Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
3003 info in the "About" dialog.
3005 + Fix to set the correct filename on the root of the survey tree - previously
3006 the filename of the previous file loaded was used!
3008 + The movie export code now works with newer versions of the FFmpeg libraries
3009 as well as still working with older versions.
3011 + Fix mixed up messages - the print dialog now says "View" on the left
3012 subgroup of controls rather than some unrelated message.
3014 + On printouts, combine the "Plan View"/"Elevation" info box field with the
3015 field which gives the bearing and reduce the height on the info box by the
3016 removed field, so it's now 3cm for plans and elevations, as for extended
3017 elevations. Report the tilt angle for tilted elevations which it seems has
3018 been missing for ages (it's not in recent 1.0.x either).
3020 + Tweak the exact positioning of informational text on printouts to look
3021 nicer and make better use of the available space.
3023 + Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
3026 + Make the sign of the tilt angle for printouts consistent with the sign
3027 shown by the "clino" in the survey pane.
3029 + In the "Print" dialog, when in plan view disable the "Plan view" button,
3030 and similarly for the "Elevation" button.
3032 + (Microsoft Windows version): Sort out appearance of custom cursors.
3034 + If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
3036 + (Mac OS X version): F11 puts aven into full screen mode, but apparently
3037 you can't get out again easily, so add code to explicitly check for F11
3038 being pressed and toggle full screen.
3040 * (Linux version): Fix the RPM .spec file for where man pages now get installed
3041 and package aven.svg and the vim support files. (Fixes from James Begley)
3043 * "make check" now performs several checks on the translation files.
3045 * More messages are now available to be translated.
3047 * cavern: Fix reporting of ranges of survey coordinates, which was broken by
3048 the message handling changes in 1.2.0.
3050 * Fix warning when compiling with GCC.
3052 * INSTALL: Mention building wxWidgets with --enable-unicode. Mention using
3053 sudo for installing on Unix.
3055 * In the manual, replace the instructions for building from source with a
3056 pointer to the clearer instructions in INSTALL.
3058 * In the manual, make it clear that installing with administrator rights
3059 also applies to newer platforms than XP.
3061 * doc/TODO.htm: Update.
3063 Changes in 1.2.0 (2011-09-20):
3065 * Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
3068 * tests/smoke.tst: aven no longer requires an X display for --help or
3069 --version, so replace skip of this check with a check that this remains the
3072 * We now use the standard .po and .pot file formats for storing translations
3073 (rather than the Survex-specific messages.txt format), and then translate
3074 these into Survex's .msg format.
3076 * (Unix version): Move survex man page to section 7 (since it isn't documenting
3079 * (Unix version): Write each generated man page to a temporary file, then
3080 atomically rename, to avoid leaving an empty or partial man page behind if
3081 docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
3082 recurrence of that).
3084 * (Unix version): Default to installing docs into /usr/share/doc/survex rather
3085 than /usr/doc/survex.
3089 + Fix handling of accented characters in the survey pane.
3091 + Aven icon redrawn in SVG format - it's now a vector image which looks
3092 nicer at larger sizes.
3094 + Explicitly request double-buffering, which seems to be needed for systems
3097 + Fix crash while trying to load certain .3d files.
3099 + Movie export code updated to work with more recent versions of FFmpeg.
3100 Currently this is disabled in Microsoft Windows builds, pending getting the
3101 required libraries set up for building releases.
3103 + Reporting of errors during movie export improved.
3105 + Force playback speed to "x1" during movie export.
3107 + Use stock IDs for buttons where appropriate - such buttons may now be
3108 rendered with icons on some platforms.
3110 + If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
3113 + (Unix version): Remove special handling for toggling "full screen" on wxGTK
3114 as it's no longer required with modern versions.
3116 + Don't redraw the survey on every mouse movement in the survey pane unless
3117 the measuring line is (or just was) active. (ticket #17)
3121 + Drop "non-fatal" from the report of how many errors there were at the end
3122 of the run - it just confuses users - we won't even get here if there's a
3125 + Add --3d-version option to allow the user to specify the version of the 3d
3126 format to output. (ticket#21)
3130 + Make the highest and lowest valid values for img_output_version available
3131 in img.h as IMG_VERSION_MIN and IMG_VERSION_MAX.
3133 * (Mac OS X version): Fix buildmacosx.sh script to check where the temporary
3134 volume actually gets mounted. Fix URL for downloading wxWidgets.
3136 Changes in 1.1.16 (2011-05-16):
3138 * Translation updates for German, Spanish, Italian, Portuguese, Brazilian
3139 Portuguese, and US English.
3141 * Use horizontal ellipses character rather than '...' and right arrow character
3142 rather than '->' where these characters are available.
3144 * (Unix version): Link with -lGL, if it exists, to support linking with gold or
3145 GNU ld --as-needed (Debian bug #615781).
3149 + Fix code typo for IMG_API_VERSION == 0 case.
3151 + Fix code typo in code used when IMG_HOSTED isn't defined.
3153 * doc/TODO.htm: Remove entries which have now been done.
3155 * (Microsoft Windows version): aven: We now include all the available
3156 translations for messages from wxWidgets, which means that standard widgets
3157 will appear translated where available even if Survex messages aren't
3160 Changes in 1.1.15 (2010-10-15):
3164 + In the cavern log window, change the "Rerun" button to "Reprocess" to
3165 follow terminology in manual and elsewhere. Fixes ticket#15.
3167 + When displaying output from cavern, don't update the window after every
3168 line, but only when we don't have data from cavern pending. Hopefully
3169 addresses ticket#12.
3171 + If we aren't using GL_POINTS for blobs, draw them using a series of
3172 abutting lines rather than with gluDisk which is faster and gives a
3175 + Check whether blobs and crosses actually render correctly as points/point
3176 sprites, and if they don't, fall back to drawing them with lines. The
3177 best method is cached on disk, and rechecked automatically if the graphics
3178 hardware is changed or the drivers upgraded.
3180 + Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
3181 though, so we still enable USE_FNT by default).
3183 + Don't offer "All files" wildcard in presentation save dialog.
3185 + (Microsoft Windows): Handle filenames with non-Latin1 characters in in
3188 + (Microsoft Windows): Quote filenames with spaces and metacharacters in
3189 when running cavern from aven. Fixes ticket#11.
3191 * editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
3193 * diffpos: Handle files with duplicate labels in better - extend generates
3194 duplicate labels when it breaks a loop.
3196 * Enable eswap-break testcase now that diffpos handles duplicate station names.
3198 * New v7 of .3d format which stores survey dates as number of days since
3199 January 1st 1900, so we now support dates from 1900-2078 (rather than
3200 1970-2037) with a smaller file size. The img API is now versioned - you
3201 can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
3202 gives the survey dates in days in days1 and days2 instead of as time_t
3203 values in date1 and date2. Fixes ticket#14.
3205 * Consistently use http://survex.com/ rather than http://www.survex.com/ - the
3206 former has been the canonical name for some time, with www.survex.com just
3209 * (Unix version): Use unlocked file I/O if available, which can be much faster
3210 in some cases (we don't need the locking as we don't do multithreaded file
3213 * (Mac version): Fix compilation failure due to clash with Point in Mac OS X
3216 * (Mac version): buildmacosx.sh now works again.
3218 * Most tests weren't actually running any testcases (looks like a sh
3219 portability issue). This is now fixed, and fortunately all tests still pass.
3221 * Include the extra .isl translation files for Innosetup in the source archive.
3223 Changes in 1.1.14 (2010-07-26):
3225 * Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
3229 + After processing survey data, if there were warnings or errors, add a
3230 "Rerun" button to allow easy reprocessing after fixing problems. If there
3231 were only warnings, also add an "OK" button to allow moving on to viewing
3232 the processed survey data (fixes ticket#13).
3234 + Optimise updating of the cavern log window (hopefully fixes ticket#12).
3236 + Fix links in cavern log window to link from exactly '<file>:<line>' (and
3237 not the ': ' after), and to make the title for the terminal the
3238 warning/error message. Avoid false positives by checking that '<line>' is
3241 + Don't double escape the contents of href and target in links in the cavern
3244 + Improve handling of the splitter window, fixing behavioural glitches in
3247 + Highlight stations matching any current search when a file is loaded.
3250 + (Mac version): Fix build issue due to Mac OS X polluting the global
3251 namespace with its own "Point" class.
3253 + (Unix version): The Gnome print dialog has its own preview window so
3254 suppress ours if using the Gnome one.
3256 + (Unix version): Link aven with -lGLU which SuSE Linux needs.
3258 + (Microsoft Windows version): Fix handling of a double-click on the survey
3259 tree when built with wxWidgets >= 2.8.11.
3261 * cavern: Report relevant file and line number for three warnings which didn't
3264 * (Unix and Mac versions): configure: Update the wx-config probing code -
3265 wxmac-config etc aren't present with newer wxWidgets versions so there's no
3266 point looking for them now.
3268 * (Mac version): buildmacosx.sh: This script builds a diskimage with Survex in
3269 for easy installation. Update it to work with the latest Survex versions
3270 (use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
3271 private wxWidgets, use 2.8.11 not 2.7.0-1).
3275 + Correctly capitalise "GTK".
3277 + Note that on Linux we only regularly test builds with the GTK+ version
3278 (change taken from 1.0).
3280 * Fixed the cad3d man page, which was an empty file in 1.1.13.
3282 Changes in 1.1.13 (2010-06-16):
3284 * Say "wxWidgets" instead of "wxWindows" consistently.
3286 * img.c: Fix small memory leak (filename_opened member).
3288 * cad3d, aven: Fix export to SVG when a label contains a '%' character.
3292 + wxWidgets 2.6.0 or newer is now required.
3294 + A "Unicode" build of wxWidgets is now supported. An "ANSI" build may still
3295 work but hasn't been tested recently (all packaged versions of wxWidgets
3296 seem to be Unicode now).
3298 + Fix potential uses of uninitialised variables which may have been causing
3299 occasional glitches when loading a file on start-up.
3301 + Improvements to the handling of the font used for plotting labels and other
3302 text on the survey pane:
3304 - Loading the font file is more efficient.
3306 - Character spacing is improved.
3308 - Default font is now anti-aliased.
3312 - Add "Copy" button to copy the system info to the clipboard for easier
3315 - List OpenGL extensions last, since there are usually lots of them with a
3318 - Fix 100% CPU usage while the "About" dialog is open.
3320 + Processing .svx files:
3322 - Passing a .svx file on the command line now works better.
3324 - Put the survey data log window in a splitter in the usual frame rather
3325 than opening a separate frame for it.
3327 - Auto-scroll the log window until we've reported a warning or error.
3329 - Fix small memory leak.
3331 + The presentation filename now defaults to using the basename of the
3332 currently loaded dataset, but we always prompt before we first save with
3335 + Reduce memory usage when saving a screenshot.
3337 + Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
3338 persist the window size (and maximised or fullscreen state) between
3341 + Fix reporting of OpenGL errors.
3343 + Fix glitches when tilting while looking East.
3345 + Added Portuguese and Slovak translations of wxWidgets messages.
3349 + Rationalise manual formats - replace PostScript with PDF and drop RTF.
3351 + Drop the "alternative manual formats" self-extracting zip file - people
3352 will generally just want one of the formats, so downloading several
3353 together isn't very useful.
3355 + 3dformat.htm: Update for v6 format (thanks to Mike McCombe).
3357 + GPL.htm: Replace HTML version of licence with a link to the version on
3360 + ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
3361 low level to be of interest to non-developers, and developers can look at
3364 * (Unix version): configure: New preferred name for specifying wx-config script
3365 is WX_CONFIG. WXCONFIG still supported for compatibility.
3367 * (Linux version): Source RPM package dropped as you can just build an RPM
3368 package from the source tarball.
3370 * (Microsoft Windows version): The installer is now created with a newer
3371 version of InnoSetup, which gives a 10% smaller download.
3373 Changes in 1.1.12 (2007-02-07):
3377 + Remember the window size or maximised/fullscreen state between invocations.
3379 + Add options dialog to "Export" similar to the one for "Print".
3381 + The "number of pages required" in the print dialog now updates when you
3382 change what is to be shown (underground legs/surface legs/station
3385 Changes in 1.1.11 (2006-11-25):
3387 * Updated Czech, Spanish, and Slovak translations.
3389 * (MacOS X version): Assorted OS X specific tweaks and fixes.
3393 + Pick a smaller and clearer font for labels.
3395 + Fix character spacing.
3397 + Tweak display of bearing and elevation angles to look nicer with
3400 + Use the title from the 3d (or plt, etc) file for the window title
3401 rather than the filename.
3403 + Show distances to 2 decimal places rather than the nearest integer.
3405 + Only consider underground legs when calculating the depth bands and
3408 + Add "Colour by Error".
3410 + Add entry for "white" in date and error keys.
3412 + When setting the view to a single point, don't change the scale.
3414 + If reloading the same file, don't change the view
3416 + Fix filetypes selector in open dialog.
3418 + Fix the charset we use for aven in certain cases.
3420 + Call msg_init before using msg_lang or it won't ever be set!
3422 + Pass wx the full language code to initialise the C library locale.
3424 + Fix bug in generating prefix tree view which could lead to a bogus
3425 leading dot on some survey names (bug probably introduced in 1.1.10).
3427 + "New Presentation" now ensures that the side panel is open
3429 + Fix updating of cached opengl lists when the view is reset to the
3432 * Ignore LANG if it starts with a digit to avoid problems with bogus value for
3433 LANG which AutoCAD installation seems to set on MS Windows.
3435 * (Unix version): configure: Allow SGMLTOOLS and DOCBOOK_TO_MAN to be
3436 specified. Either/both can be set to ":".
3438 * dump3d: Report unknown (to dump3d) codes returned by img.
3440 * img library: Flag all stations as underground in the old "ASCII" .3d format.
3442 Changes in 1.1.10 (2006-07-14):
3444 * aven: Clicking on a survey name in the survey tree now highlights it in
3445 the map view. Double-clicking zooms the view to show the clicked survey
3446 highlighted. Clicking the root clears the highlighting and double-clicking
3447 the root restores the default view. To expand/collapse a branch, click
3448 on the "[+]" or "[-]" icon to the left of the survey name.
3450 * aven: The measuring line can now measure to anywhere in plan or elevation
3451 view (not just to a station!) In plan view the horizontal distance and
3452 bearing are shown, while in elevation view the vertical distance is shown.
3454 * aven: Moving the mouse over a station in the survey view now highlights
3455 that station in the survey tree (though it may not be visible if the
3456 survey(s) it is in aren't expanded).
3458 * aven: Clicking on a station to centre the view now moves the mouse pointer
3459 to the new location of the station (except on Mac OS X where this isn't
3462 * aven: Fix which presentation toolbar buttons are shown as depressed.
3464 * Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
3466 * vim files are now installed with the correct paths (bug introduced in 1.1.9).
3468 Changes in 1.1.9 (2006-07-04):
3470 * (Unix version): Install desktop files for aven and svxedit contributed to the
3471 Ubuntu package by Phil Bull, and corresponding pixmaps.
3473 * Fix img to filter out cross-sections which don't match the subsurvey (if
3474 specified). The API now returns img_XSECT_END to mark the end of a
3475 passage rather than setting a flag on the last img_XSECT of the passage.
3477 * Enhance integration with the vim editor - this can now colour .err files, run
3478 cavern from vim and parse error output, and run aven from vim. Tweak the
3479 existing vim mode for .svx files to fix a few minor bugs and add support for
3480 the new "*data passage" style.
3482 * aven: fix drawing of the "blob" end of the measuring line on graphics cards
3483 which can't draw large enough blobs for us.
3485 * aven: sort out confusion about what encoding everything is in which means
3486 that the distance measured by the measuring line actually gets displayed
3487 and also fixes problems with empty menu items in non-English locales in
3490 * aven: redraw grey background after a menu is closed over the aven window
3491 with no survey loaded.
3493 * aven: fix bug which caused printing to crash (introduced in 1.1.8).
3495 * aven: avoid crash on some machines when opening "About" dialog before having
3498 * aven: Translate "Plan" and "Elevation" buttons in print view dialog.
3500 * (Unix version): aven: Fix character set handling of cavern output.
3502 * cavern: Report an error if a cross-section is specified for a station which
3505 * Updated French and Italian translations.
3507 * (Unix version): aven: Fix "Can't open message file `en_US' using path
3508 `${prefix}/share/survex'" error.
3510 * Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
3511 (doesn't affect Survex itself, but other applications which use img.c should
3514 * (Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
3515 and later are caught by configure, whereas older wx versions are caught when
3518 Changes in 1.1.8 (2006.06.30):
3520 * Drop support for building with wxWidgets versions prior to 2.4.0
3521 (which was released on 2003-01-07).
3523 * aven: Printing through aven now uses settings from the "[aven]" section
3524 of print.ini, and support for hierarchical sections (using "like=")
3527 * aven: Change mouse actions to be compatible with those in Survex 1.0.
3528 The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
3529 left drag is now smart about not rotating and zooming at the same
3532 * aven: Highlighting stations now happens as you type, and pressing
3533 "Enter" or clicking the "Find" button now pans and zooms to show the
3534 highlighted stations.
3536 * aven: Left-clicking away from a station now cancels measuring line.
3538 * aven: Setting view to North, South, East, or West is now animated like
3539 the tilt from plan to elevation.
3541 * aven: Fix presentation saving to also write "." for decimal points and
3542 presentation loading to accept either "." or ",".
3544 * (Unix version): aven: Add text for all toolbar items so that aven
3545 will work with the Gnome desktop preference for displaying toolbars as
3546 icons with text or just text (wxWidgets needs fixing first though).
3548 * (Unix version): aven: Remove the ability to detach the menu bar (yell
3549 if you actually used it and I'll restore it!)
3551 * aven: Add "all survey files" option to the "open file" dialog.
3553 * (MS Windows version): aven: Fix cursor keys to pan survey.
3555 * (MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
3557 * (MS Windows version): Fix installer to work on Windows 2000 or XP if
3558 run by an unprivileged user.
3560 * (MS Windows version): Upgrade to the latest version of InnoSetup (the
3561 installer builder we use) and include new installer translations for
3562 UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
3564 * (MS Windows version): aven: Include Catalan and Brazilian Portuguese
3565 translations of messages for wxWidgets (the GUI library we use).
3567 * aven: Disable "Highlight exported points" if there aren't any.
3569 * Updates to French translation from Michel Bovey. Also updates to German,
3570 Italian, Catalan, Spanish, and Romanian translations.
3572 * (Unix version): test suite: fix smoke test to pass even without X running
3573 (it was meant to but the code had a bug).
3575 * aven: Check if OpenGL is available and exit cleanly with a helpful error
3578 * (Unix version): aven: Fix --help and --version to work without a working
3579 X display (provided it's built with wxWidgets 2.5.1 or newer).
3581 * aven: Automatically select the presentation tab of the notebook when the user
3582 selects "New Presentation" or "Open Presentation".
3584 * aven: Fix "Delete" in the presentation list to not get passed on (and so not
3585 reset to default view as well).
3587 * aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
3590 * aven: Fix Cursor Up and Down in the presentation list to move the highlight
3591 up and down instead of being passed on and moving the survey.
3593 * aven: Improve SVG output compatibility. Tested with Mozilla Firefox 1.5,
3594 Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
3595 Safari 2.0.3, and InkScape 0.42.
3597 * aven: Put a 5mm border around exported SVG files to allow for station markers
3598 and non-zero width lines.
3600 * aven: Fix crash when exporting as SVG or Sketch if labels or surface data
3603 * aven: Actually close the file we're exporting which fixes problems with it
3604 not always being fully written.
3606 Changes in 1.1.7 (2005.10.18):
3608 * cavern: Add validity checking for dates in *date commands (with feature
3609 test in testsuite). A date entered as just "year" or "year.month" now
3610 becomes a date range for the relevant period (previously it became a single
3611 date near the middle of that period).
3613 * extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
3616 * extend: Default output name for a file called input.3d is now input_extend.3d
3617 rather than just extend.3d (which was annoying if you wanted to extend
3618 several surveys in the same directory).
3620 * aven: OpenGL 2.0 always includes support for point sprites so rework
3621 our check for them to include that knowledge.
3623 * aven: Regenerate depth bar if user switches to/from metric units.
3625 * aven: Don't clear the "there" mark just because the mouse pointer has
3626 moved off a station.
3628 * aven: When processing a .svx file, put the resultant .3d file in the
3629 same directory (since that's where we then try to load it from).
3631 * aven: Fix labelling of date colouring on 32 bit platforms.
3633 * aven: If "colour by date" is on and we load a survey with no date info
3634 (or all surveyed on the same date) then set "colour by none".
3636 * aven: Make the error dialog modal and remove a signal handler once it
3637 has fired to prevent endless (or seemingly endless) cascades of error
3640 * aven: Enforce a minimum object volume diameter of 1m to avoid problems
3641 if a survey file with only one station in is loaded.
3643 * aven: Fix problems with indicators disappearing when we're drawing
3644 blobs and/or crosses the slow (but always supported) way. (Problem
3645 introduced in 1.1.6).
3647 * (Unix version): aven: Really stop setting extra toolbar margin when using
3648 GTK2.0. The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
3649 set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
3651 * (Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
3652 we've been compiled with, and which GTK+/Motif version where appropriate.
3654 * (Unix version): Fixed build on Fedora Core 3.
3656 * documentation: Updates to 3d file format specification from Mike McCombe.
3658 Changes in 1.1.6 (2005.10.10):
3660 * (MS Windows version): Distribution is about a third smaller than 1.1.5
3661 (mostly because mingwm10.dll is no longer required).
3663 * aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
3664 it, showing cavern's output in a window (with errors and warnings clickable
3665 to load the offending file into an editor), and then loading the resulting
3668 * aven: Added "Colour by Date" option.
3670 * aven: Disable "Colour by Depth" option if there's no elevation variation.
3672 * aven: Don't crash if trying to load a survey with no elevation variation.
3673 Instead turn off depth colouring.
3675 * aven: Export as HPGL added.
3677 * aven: Improved update of mouse coordinates and measuring line (thanks to
3680 * aven: Show the coordinates of either the mouse pointer or the nearest
3681 survey station to it (if there is one near enough). Showing both was
3682 confusing and meant the status bar overflowed on smaller displays.
3684 * aven: When printing an extended elevation, don't show bearing and elevation.
3686 * aven: Don't lock "flat" surveys which aren't extended elevations - a
3687 flat survey with LRUD data isn't flat any more!
3689 * aven: When we have to draw blobs and crosses the slow way (because the
3690 graphics hardware doesn't support the fast way), draw them so that they
3691 should appear at the correct depth into the 3D scene instead of on top
3694 * aven: Make "play presentation backwards" icon green to match the other
3697 * (MS Windows version): aven: Mouse clicks on the survey view now set the
3698 keyboard focus there.
3700 * (MS Windows version): aven: Fix first redraw of a newly loaded survey.
3702 * (MS Windows version): aven: Fix redrawing of measuring line.
3704 * cavern: Store dates for img_XSECT.
3706 * cavern: Fixed small one-off memory leak if you specify -o more than once.
3708 * (Unix version): Check environmental variable LC_MESSAGES when deciding what
3709 language to use for messages.
3711 * (MS Windows version): "Print" on a 3d file now prints through aven rather
3712 than the separate printer driver (Unix has done this for some time).
3714 * Removed old printer drivers.
3716 * img library: When creating a 3d file, ignore img_XSECT if we've been asked
3717 to write a file format version which doesn't support it.
3719 Changes in 1.1.5 (2005.09.20):
3721 * (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
3723 * aven: Make blobs round like they are in Survex 1.0.
3725 * aven: If the graphics drivers don't support drawing blobs using OpenGL
3726 point markers, fall back to drawing filled circles.
3728 * aven: If the graphics drivers support it, draw crosses as texture mapped
3729 OpenGL point markers which is much faster.
3731 * aven: Cross size increased to match Survex 1.0.
3733 * aven: We must update which blobs are displayed if display of surface or
3734 underground legs is toggled.
3736 * cavern: Fix handling of a *solve followed by survey data, none of which is
3737 attached to the previous data.
3739 * cavern: Fixed "No survey data" error when a *solve is followed by another
3740 *solve (or the implicit solve at the end of processing) with no data between
3743 Changes in 1.1.4 (2005.09.19):
3745 * aven: Added Aven's icon to the "About" dialog.
3747 * aven: Use localised character for the decimal point (e.g. "," in most
3748 continental European countries).
3750 * aven: Previously the survey tree would get focus and then take keypresses
3751 (e.g. "P", "L", "Delete"). Now we pass most keypresses across so they
3752 operate on the cave, and transfer the input focus across when we do.
3754 * aven: Make pressing "Return" in the tree control expand/collapse a subtree.
3756 * aven: Speed up intialisation by delaying creation of OpenGL lists until
3759 * aven: Added Mark Shinwell's bounding box with shadow of the survey.
3761 * aven: Disable the "Tubes" button/menu item when there's no LRUD data.
3763 * aven: Reworded "Restore Default Settings" as "Restore Default View".
3765 * (Unix version): aven: Set sensible default margins for printing and preserve
3766 any margin values the user specifies between runs (previously margins
3767 defaulted to 0 each time aven was run).
3769 * Documentation: Document *DATA PASSAGE in the manual.
3771 Changes in 1.1.3 (2005.09.07):
3773 * (Microsoft Windows version): Fixed build problems.
3775 * cavern: Allow OMIT character (-) for left/right/up/down.
3777 * aven: Remove an unnecessary menu separator.
3779 * aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
3781 * aven: Make the tooltip for "Hide" show the number of found stations.
3783 * aven: If * or ? is used in a glob-style pattern, force a non-substring match.
3785 * aven: Enable "New Presentation" when there's a 3d file loaded, rather than
3786 when there's a presentation loaded.
3788 * aven: Make entrances green in side panel tree list to match green blobs used
3791 * aven: Don't show surface labels if we're not showing surface data, etc.
3793 * aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
3794 make "Space" the key for this. Keep Return working "Stop Rotation" so
3795 existing users are happy, but don't advertise it.
3797 * aven: Normalise filename by adding any extension used, and use the normalised
3798 filename for file history and window title.
3800 * (Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
3801 as the toolbar buttons already have a sensible margin - the extra margin is
3802 only needed with GTK1.2.
3804 * aven: Fix handling of plumb legs in tube model.
3806 * aven: Fixed swapped L and R in tube model.
3808 * extend: Preserve UD cross-section information in extended elevation.
3810 * extend: Add new messages for John Pybus' enhancements.
3812 Changes in 1.1.2 (never formally released):
3814 * Added support for LRUD data in .svx files, in .3d files, and aven can
3815 now load and display it on screen and on printouts. The ability to "fake"
3816 LRUD data in aven is gone for now but will reappear in some form later.
3818 * cavern: Removed support for writing Chasm's 3dx format. We're going to
3819 fold any desirable missing chasm functionality into aven.
3821 * aven: Rearranged mouse actions as discussed on the mailing list. Added
3822 cursors for each different mouse action to help the user learn what each
3823 does. Also added cursors for the "compass" and "clino" as well as the
3824 scalebar to suggest to the user that they can be dragged to change the view.
3826 * (Unix version): aven: Don't segfault if LANG isn't a known language.
3828 * tests/smoketest.tst: If X windows is running, check that we can run aven
3829 with --help and --version.
3831 * tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
3832 no results are listed for it. This revealed that there was a "newline" test
3833 which should have been called "badnewline", and was a broken testcase too!
3834 Fixed all these problems.
3836 * cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
3837 and omitted forward compass/clino readings in Compass DAT files. Added
3838 a feature test for this to the testsuite.
3840 * It no longer makes sense to have an option not to build aven or to build aven
3841 without OpenGL so remove old machinery for this from configure and the
3844 * (Unix version): configure: Check if "-lXxf86vm" is needed.
3846 * configure: Better output for strcasecmp test.
3848 * aven: Fix crosses to work much better. Not a total fix - their position
3849 in the Z buffer isn't correct and they're rather slow to plot.
3851 * aven: Don't regenerate the hittest grid every time the mouse moves while
3852 animating, which solves the mysterious pausing effect (thanks go to Martin
3853 Green for spotting this!) Also clear all the status bar coordinates when
3856 * aven: Sort out clashing menu shortcuts in some languages.
3858 * aven: Fixed compilation problem on x86_64
3860 * SPUD: Pruned out stuff which has been done or which is not actually relevant
3863 * Merge various changes from 1.0 branch:
3865 + aven: Port over "printing from aven" functionality.
3867 + aven: Port over "export as" functionality,
3869 + Add David Loeffler's vim mode for .svx files.
3871 * aven: Fix check for whether a label is behind us in perspective view.
3873 * aven: Don't use an opengl list for drawing the indicators - we typically make
3874 a new list each time we plot them anyway.
3876 * Remove lingering traces of support for RISC OS and pre-386 MSDOS
3878 * aven: Set icon on non-Windows platforms too. This means that with
3879 WindowMaker on Unix you get an icon on the AppIcon by default.
3881 * configure: Update wxWindows checks to handle newer wx versions.
3883 * Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
3884 problems. They also all require Perl 5.8 now (hopefully this isn't an issue
3885 for anyone building from CVS).
3887 * acinclude.m4: Quote macro name for fix autotools warning.
3889 * Documentation: "tilt up" is "'" not ",".
3891 * aven: Add support for mousewheels (to tilt the cave).
3893 * aven: Fixed twisted transitions to and from pitches in certain cases.
3895 * aven: Pick a sensible initial window size when the user's desktop is spread
3896 over more than one monitor (works best with wx2.5 or newer, but try to do
3897 better with wx2.4 or earlier as well).
3899 * aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
3900 contents being visible before any survey is loaded.
3902 * aven: Allow a coloured texture to be used
3904 * aven: Don't initialise until we have data (to the user, this means the window
3905 is default colour (grey for most systems) not black until a survey is
3908 * aven: Fixed weird "shadowed" icons.
3910 Changes in 1.1.1 (2004-10-06):
3912 * (Microsoft Windows version): aven: Hopefully fix loading a survey file at
3915 * aven: Delay loading the bitmap for the "About" dialog until it is first
3916 needed. We want start up to be as quick as possible.
3918 Changes between 1.0.32 and 1.1.0 (never formally released):
3920 * NOTE: Survex 1.1.X releases are development snapshots made available for
3921 the purposes of allowing wider testing and getting more user feedback. Once
3922 the code has stabilised the version number will be raised to 1.2.0.
3924 * aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
3925 you're using Windows 95 - these can be obtained from:
3926 http://download.microsoft.com/download/win95upg/info/1/W95/EN-US/Opengl95.exe
3928 * aven: Solid passages - passage dimensions are currently inferred from
3929 the leg length (pretty effective as you can measure longer legs in
3930 larger passages). Use of real LRUD data coming soon...
3932 * aven: Depth colouring is now continuously varying.
3934 * aven: Colour by depth can now be turned off (and there's the start of a
3935 framework for properly implementing colour by date, error, etc).
3937 * aven: Find stations moved onto the toolbar and now uses a simple wildcarded
3938 match (? matches any character, * matches any number of characters).
3940 * aven: We now use the status bar for coordinates, distances, etc to make
3941 better use of screen space.
3943 * aven: Full screen mode (F11).
3945 * aven: Perspective view.
3947 * aven: Context sensitive cursor shape - needs more work.
3949 * aven: Mouse actions changed (hopefully they're now more natural, but
3950 you may find the change disorientating - feedback wanted on this).
3952 * aven: Added "presentations" which allow you to set up fly-through paths
3953 and load/save/run them.
3955 * aven: A presentation can be exported as a movie file.
3957 * aven: Added Save screenshot facility.
3959 * aven: Depth fogging option.
3961 * aven: Added Smooth Lines option.
3963 * aven: Added Textured Walls option.
3965 * aven: If a survey has surface legs but no underground legs, default to
3966 showing the surface legs.
3968 * cavern: Dates given to *date are now stored in the 3d file.
