1 Changes in 1.4.2 (2022-02-25):
3 * aven: Fix to be compatible with FFmpeg 5.0.
5 * Improve docs for *cs and *declination.
7 * cavern: Fix "*declination auto" not to crash when built with PROJ < 8.1.0.
8 Bug introduced in 1.4.0.
10 * cavern: For each `*declination auto` command cavern now reports an "info"
11 message showing the range of calculated declination values and the dates at
12 which the ends of the range were obtained, and also the grid convergence
13 (which doesn't vary with time). Fixes #92, reported by Rob Eavis.
15 * cavern: If any of the N-S, E-W or U-D ranges includes an anonymous station
16 then also report the range in that direction excluding anonymous stations.
17 Patch from Thomas Holder.
19 * cavern: The error from a bad `*cs custom` command now highlights the quoted
22 * cavern: "FIX command with no coordinates - fixing at (0,0,0)" is now an
23 "info" rather than a "warning". It's not really reporting a problem and the
24 ability to omit the coordinates is a deliberate feature. It is useful for
25 the user to know where the "*fix" without coordinates is if they want to
26 change the survey to be in real coordinates, so an "info" diagnostic is a
27 good fit. This also means aven will no longer stay on the log view after
28 processing a dataset which fixes without coordinates.
30 * cavern: If "*fix" is used twice with no coordinates we no longer say
31 "FIX command with no coordinates - fixing at (0,0,0)" right before:
33 error: Already had FIX command with no coordinates for station "x"
35 * cavern: Include errors in Compass .mak files now report the error in the line
36 where the included filename is actually specified.
38 * cavern.tst: Add test coverage for warnings for *entrance and *export with
39 a station which doesn't exist otherwise.
41 * aven/survexport: Change JSON export to be valid JSON. This means the output
42 has changed incompatibly, but it wasn't valid JSON before which suggests
43 nobody was actually successfully using it. Fixes #128, reported by Pawczak.
45 * aven.tst: Skip one testcase on macos as it seems to hang, at least when
46 running on the Continuous Integration system.
48 * (Microsoft Windows version): The installer is now generated with a much
49 newer version of Innosetup. Most notably, it now supports installing as a
50 non-admin user. This also means Microsoft Windows Vista is now the minimum
51 supported version but 2000 and XP are both many years out of support anyway.
53 * (Microsoft Windows version): The coordinate system database for PROJ is
54 now included so "*cs" now works (broken since 1.4.0).
56 * Chinese translation updates from Qingqing Li.
58 * Building from source now requires a compiler with support for C99. C99
59 seems to be universally supported by compilers now so we don't expect this to
62 Changes in 1.4.1 (2021-11-08):
64 * This release should work with any PROJ version >= 6.2.0.
66 * cavern.tst: Fix to actually run tests when building outside the source
67 tree. Previously files for testcases weren't found, and tests were skipped
68 with a warning, which lead to 1.4.0 being released with two failing testcase.
69 Fix to find the files, and make not finding them an error.
71 * cavern.tst: Fix testcases gpxexport and require_fail which were failing
74 * 3dformat.htm: Document that coordinate system can be ESRI:<number>.
76 Changes in 1.4.0 (2021-11-06):
78 * New release series to mark that Survex now uses the new PROJ API, and
79 requires PROJ >= 7.2.0. Survex 1.2.x will continue to support PROJ < 8
80 (and won't support newer PROJ versions). Fixes #102, reported by Bas
83 Due to these changes, PROJ will now convert directly between coordinate
84 systems where it knows how to, instead of always converting via WGS84.
85 This means conversions may now be more accurate in some cases, and you may
86 notice station coordinates changing - these should be for the better.
88 Also, the vertical datum is now taken into account automatically, and
89 terrain data now aligns much better vertically with surveys. Fixes #56.
91 * aven: Clicking and holding the left mouse button on the compass or clino,
92 then (while still holding) clicking the right button no longer causes a
93 wxWidgets assertion to fail. Reported by echarlie.
95 * img library: Rewrite certain proj strings when reading 3d files for
96 better compatibility with newer PROJ versions, where use of proj
97 strings is strongly discouraged.
99 `+init=epsg:` followed by a code number is rewritten to `EPSG:`.
101 `+init=esri:` followed by a code number is rewritten to `ESRI:`.
103 The proj strings which cavern used to put in 3d files for UTM zones and
104 S-MERC are rewritten to `EPSG:` follow by the appropriate code number.
106 * Also install survex.lang for gtksourceview 4. Fixes #125, reported by Martin
109 * Fix missing data style in interleaved example in manual. Reported by
112 * Use jw from docbook-utils instead of sgmltools-lite to process the manual.
113 The sgmltools-lite homepage says it's no longer being developed, and suggests
114 docbook-tools (which Debian packages as docbook-utils) as a replacement.
116 * doc/HACKING.htm: Update Debian packages to install
118 * doc/HACKING.htm: Update details of setting up mingw cross-build environment.
120 * Add simple tests for GPX and KML export.
122 * Expand cavern testcase csbad.
124 * cavern.tst: Parse warning/error counts more robustly. Previously we'd get
125 confused if the final line just contained an integer, e.g. if we end listing
126 stations not attached to a fixed point.
128 Changes in 1.2.45 (2021-03-09):
130 * Avoid undefined signed shifts in 3d file handling. Survex itself is only
131 affected on big-endian platforms (so most Linux machine, Microsoft Windows,
132 and current Macs are all OK), but this also affects the img library on all
133 platforms when used in standalone mode as it is in other programs. Fixes
134 #119, reported by Matěj Plch.
138 + When reading cavern output for the log window, we need special handling
139 for the case when a chunk of output ends mid-way through a UTF-8
140 sequence. Previously we lost the first byte of the sequence in this
141 case (and would then show it as an invalid character), but now it is
142 handled correctly. In practice, most of the cavern log output is ASCII so
143 it's quite possible nobody's ever actually hit this.
147 + Suppress reports of leaks on exit from the LeakSanitiser debugging tool.
148 We know we don't release all memory explicitly on exit since doing so would
149 mean extra work for no reason as the OS reclaims all memory when the
152 * Convert OLDNEWS encoding from ISO-8859-1 to UTF-8.
154 Changes in 1.2.44 (2021-02-10):
158 + (Microsoft Windows version): Now using wxWidgets 3.0.5 (was 3.0.4).
162 * Add support for quadrant bearings (e.g. N30E). Patch from echarlie.
164 * Report error if angle units are specified for passage dimension.
165 Previously "*units left degrees" and similar were incorrectly quietly
166 accepted. Spotted by echarlie.
168 * Fix *data with no parameters to keep the current style and reset any state
169 as documented. Previously it actually instead ignored any survey data
170 until the next *data command with parameters.
172 * Fix minor memory leak in *data. We leaked a single memory allocation on
173 "*data default" or an invalid *data command.
175 * Improve test coverage.
179 * The check for whether a format supported --elevation, --plan, --bearing and
180 --tilt was inverted. Reported by echarlie.
182 * Fix reporting of export errors on Microsoft Windows. Reported by Matic Di
185 * img library: Fix img_open() when used in other programs. Patch from Thomas
188 * configure: Add wx-config-gtk3 to WX_CONFIG search for Arch Linux. Patch
191 * Improve documentation of interleaved data. Most notably, we now document
192 that a blank line breaks the current traverse.
194 * Fix typo in manual ('cypolar' -> 'cylpolar'). Patch from Wookey, fixes #117.
196 * Chinese translation updates from Qingqing Li.
198 * Russian translation updates from Vasily Vl. Suhachev.
200 * French translation updates from Jean-Marc and from Wassil Janssen.
202 * Bulgarian translation updates from Wassil Janssen
204 Changes in 1.2.43 (2020-02-28):
206 * cavern: Update to use v13 of the IGRF model for calculating declinations.
207 This was issued in December 2019 and should give slightly more accurate
208 declinations for surveys made since 2010.
212 + Fix colouring of "not in loop" when colouring by error. 1.2.42 introduced
213 a bug where surveys not in a loop were coloured as if they had zero error.
214 Fixes #111, reported by Bruce Mutton.
216 + Fix handling of grid in export. The grid was always getting enabled
217 (probably since 1.2.8) even for formats which don't support exporting with
218 a grid. This resulted in the bounding box being set wrongly for some
219 formats such as SVG, as reported by Richard Knapp on the mailing list.
221 + When showing errors processing the survey data we'd previously crash if
222 cavern incorrectly reported an error as being in a column off the end of
223 the line - now we just ignore the error column in this case.
225 + Support colouring by survey style ("normal", "diving", "nosurvey", etc).
227 Changes in 1.2.42 (2019-09-04):
231 + Allow colouring by horizontal or vertical error.
233 + (Unix version): Disable scaling for HiDPI displays with GTK3. The OpenGL
234 code needs work before this will work usefully, so just disable for now
235 (which simulates how things are when using GTK2).
237 + (Unix version): Fix orientation of notebook tabs when build with wxWidgets
238 3.1 development versions. We want horizontal tab orientation, but were
239 passing a weird flag combination which now results in vertical tab
242 * When exporting to a format where we support rotation in the horizontal
243 plane (such as SVG), the rotation was incorrectly applied to cross section
244 data (except for the default rotation of zero). Fixes #108, reported by
247 * Add a section to the manual covering the command line tools, and what you
248 might still need to use them for.
250 * Fix compiler warning when building from source with GCC 9.
252 * Consistently refer to macOS not OS X - Apple have renamed it yet again.
254 * (macOS version): Revert the workaround for the crash on macOS 10.14. The
255 bug we were working around is fixed in git ready for wxWidgets 3.0.5 and
256 there's a backported fix in the homebrew wxmac 3.0.4-2 package, which is how
257 we now recommend people install on a Mac. Closes #101, reported by floho.
259 * (macOS version): Remove buildmacosx.sh script since installing from homebrew
260 is now the recommended approach.
262 Changes in 1.2.41 (2019-07-10):
266 + (Microsoft Windows version): Fix error on startup in the pre-built version
267 of 1.2.39 and 1.2.40. This is a recurrence of the same issue as affected
268 1.2.33 - this time I've patched out the unnecessary check in wxWidgets
269 which causes this problem so it shouldn't recur again. Reported by
272 + (macOS version): Add work around for crash on macOS 10.14 (not fully tested
273 as I don't have access to a Mac). Hopefully fixed #101, reported by floho.
275 Changes in 1.2.40 (2019-07-04):
277 * aven: Draw the measuring line ring with an even shape. Previously the exact
278 shape of the ring varied slightly depending on the exact coordinates, which
279 could be visually distracting once you noticed it.
281 * We were casting a function pointer with a bool return type to the same type
282 but with a void return type. In practice this probably works fine on most
283 platforms, but it's undefined behaviour and also gives a compiler warning
286 * Fix bug introduce in 1.2.39 with where the "esri" data file for PROJ is
289 Changes in 1.2.39 (2019-06-29):
291 * Support versions 5.x and 6.x of the PROJ library we use for handling
292 conversions between coordinate systems. Reported by Bas Couwenberg
293 in #102, by Richard Knapp in #103 and by Martin Sluka in email.
295 * (Unix and Mac OS versions): When checking if something is a file or if it is
296 a directory, we no longer treat a symlink as being neither, but instead
297 return an answer based on what the symlink points to.
301 + Improve handling of hidden splay ends. Previously, hidden splay ends still
302 served as "targets" for snapping the mouse pointer to, and still got
303 crosses when crosses were enabled. We don't have a handy flag for "this is
304 the outer end of a splay" and computing that on demand isn't so easy to do,
305 so for now we use the "anonymous station" flag so at least these cases now
306 behave properly for splays to anonymous stations (which is likely to be
307 what people with huge numbers of splays from disto-x, etc are using). This
308 does mean that anonymous stations on continuation passages will incorrectly
309 also be off when splays are hidden, but that seems an OK trade-off for now
310 and a definite improvement over the previous situation. The snapping of
311 the mouse pointer was reported by Frank Tully in #105.
313 + Fix typo in export UI (CVS should be CSV).
317 + Add CSV to documented list of survexport output formats.
319 + Fix *declination syntax synopsis - "auto" is a literal string, not a
322 + Update PROJ project name and website - the name is now "PROJ" (all caps and
323 no ".4" suffix) and the website is now: https://proj.org/
325 * Install gtksourceview-3.0 language file so .svx files now get syntax
326 highlighting in gedit and other GtkSourceView-based editors. Patch
327 from Philip Withnall. Fixes #98.
329 * (Microsoft Windows version): The Survex installer doesn't uninstall the old
330 version when you upgrade, but just overwrites it with the new version. In
331 1.2.35 cad3d.exe was replaced with survexport.exe, but a user upgrading from
332 an older version would still have cad3d.exe from that old version. We now
333 remove any old cad3d.exe left over from a previous install in the same
334 location to avoid confusion.
336 * Add a few more message translations.
338 * Fix warnings when built with a C++11 compiler.
340 Changes in 1.2.38 (2019-03-02):
344 + Deprecate MILS as angular units. Survex has long support MILS as an alias
345 for GRADS. However, this seems to be a bogus definition of a "mil" which
346 is unique to Survex (except that Therion has since copied it) - there are
347 several different definitions of a "mil" but they vary from 6000 to 6400 in
348 a full circle, not 400. Reported by Andy Edwards.
350 + Fix segfault for *include "". This isn't useful, but shouldn't crash. It
351 now reports "file not found" instead.
353 + Use isnan() to check for not-a-number. This is cleaner, more robust and
354 more efficient than formatting the number as a string and checking for
355 "NaN" or "nan" in the result.
357 * Avoid unused variable warning when compiling from source with modern ffmpeg.
359 * Drop support for wxWidgets < 3.0. 3.0.0 was released over 5 years ago and
360 should be easily available everywhere by now. I'm no longer easily able to
361 test with wxWidgets 2.8, and this allows a significant amount of cruft to be
364 * (Linux version): survex.spec: Fedora have removed gcc from the default build
365 environment so need to explicitly list it in the BuildRequires tag. See
366 https://fedoraproject.org/wiki/Changes/Remove_GCC_from_BuildRoot for more
367 information. Patch from James Begley.
369 Changes in 1.2.37 (2018-11-18):
373 + Add basic "Colour by Survey" feature. The colours used aren't currently
376 + Fix export of splays. Patch from Thomas Holder.
378 + Fix KML export to avoid invalid geometry when a tube intersects itself.
379 Patch from Robert Jones.
381 + (Unix version): Fix to work under Wayland by forcing the x11 GDK backend
382 for now. This is a workaround until wxWidgets OpenGL support is updated
383 to work under Wayland. Reported by Philip Balister.
385 + Fix warnings about using deprecated functions when building movie export
386 code using FFmpeg 4.0.
390 + Compass MAK files: Handle fixed point coordinates in feet - previously the
391 units were ignored and the coordinates assumed to be in metres.
393 + Previously the first byte in a MAK file was ignored. Typically MAK files
394 start with a comment, and since cavern currently ignores lines that start
395 with characters it doesn't understand the meaning of, this bug would often
400 + Fix exporting of passages, walls and cross-sections by running the code
401 aven uses to decide how much to rotate each cross-section. Previously all
402 cross-sections were aligned West-East. Reported by Robert Jones.
404 + Default to .pos output if the program name is 3dtopos, and install a second
405 copy (or hardlink under Unix) as 3dtopos. This provides compatibility with
406 current releases of Tunnel. Reported by Becka Lawson, Wookey and
409 * Fix some German translations. Patch from Thomas Holder.
411 * (MacOS X version): Fix aven-create-app to not delete converted icons.
412 Typo spotted by Robert Jones.
414 * Improve documentation for *team. Document the requirement to quote names
415 unless a person is identified by just one name. Document that the roles are
416 optional, as that information may not have been recorded, and to align with
417 therion's team command.
419 Changes in 1.2.36 (2018-07-18):
423 + Add support for exporting as a CSV (Comma-Separated Values) file.
425 + Support exporting KML with altitude mode "clamp to ground". In this mode,
426 the altitude in the data is ignored and it's rendered on the surface of the
427 terrain. This is useful if your KML viewer renders the terrain as opaque
428 so underground data isn't visible. Rendering cave passages on the surface
429 isn't great, but is better than not being able to see them at all. This
430 option may also be helpful if you want to see where to look on the surface
433 + Highlight surveys with a white loop as the mouse is moved over them in
434 the survey tree. This is akin to how we highlight a station with a
435 white ring, and allows restoring "double-click survey in tree to zoom"
436 which temporarily required a quadruple-click in 1.2.35.
438 + Only show checkboxes in the survey tree for surveys not stations.
440 + Fix wxWidgets assertion if the user tried to select additional surveys
441 to show via the right-click menu.
443 + Fix multiple survey filtering when both a parent and child survey are
444 selected. In this case it makes most sense to show all child surveys of
445 the parent, but we actually showed a slightly arbitrary subset of the
446 child surveys of the parent.
448 + The checkbox area in the survey tree is now included in the area which
449 is considered by mouse-over updates such as highlighting the station or
452 + Fix display of double quotes in cavern log window (they were being replaced
453 with control character 0x16 due to a typo in the code).
455 + Add shortcuts to buttons in cavern log window.
457 + Eliminate use of gluErrorString() function which eliminates some
458 deprecation warnings when building on macOS.
460 + Reject multiple --survey command line options for now (only the last has
461 been used for a long time, but now we actually support multiple survey
462 filtering this matters more).
466 + Report a useful error when trying to convert a .3d file without coordinate
467 system information to GPS. Reported by Mark Shinwell.
469 + Handle multiple redundant --survey command line options correctly.
471 * dump3d: Report station flag "WALL", which was added in 1.2.7.
473 * Minor translation updates.
475 * Update manual for Microsoft Windows changes.
477 * tests/: Add test coverage for warnings about suspect readings
479 * Fix warning when compiling with clang.
481 Changes in 1.2.35 (2018-07-03):
485 + Viewing can now be restricted to multiple surveys. Use the right-button
486 menu on a survey in the survey tree and select "Show" to enable checkboxes
487 for that survey and all its siblings. Only the selected surveys are shown
488 on screen, printed and exported.
490 + Don't open a survey when its name is double clicked. This was happening
491 due to code added to "allow double-clicking to work on wxMSW >= 2.8.11".
492 However, reverting that change still seems to allow double-clicking to work
493 on both wxMSW and wxGTK, but fixes the unwanted additional opening of the
496 + Pick initial survey scaling based on whichever of the window width or
497 height gives the smaller scale. Previously we always used the window
498 width, which can result in parts of the cave being outside the initial
499 view. Reported by Wookey.
501 + Drop ability to specify a PROJ string in the export dialog. This was added
502 to allow exporting to formats such as GPX before we added support for
503 specifying the projection in .svx files, and that support is now mature.
505 + DXF export now uses 2 decimal places (was 6) for the bounding box, for
506 consistency with the precision used for coordinates.
508 + Fix handling of surface flag during export. In formats which discriminate,
509 legs could previously have got assigned the wrong status.
511 + Fix bug which probably prevented aven starting when OpenGL double buffering
512 is unavailable. This is unlikely to affect any common configurations.
514 + (Microsoft Windows version): Fix loading of 3d files with non-ASCII
515 filenames. Issue reported by Matic.
517 + (Microsoft Windows version): Fix incorrect display of some toolbar icons.
518 Probably broken since 1.2.17.
520 * survexport: New command-line export program which uses aven's export code.
521 Replaces 3dtopos, cad3d and findentrances, since it can do all that these
522 tools could do, plus much more.
524 * Merge more Spanish i18n updates from Evaristo Quiroga.
526 * Minor updates to various other translations.
530 + Now supports reading from and writing to an existing FILE*.
532 + Improve API documentation.
534 * (Microsoft Windows version): Fix packaging to include wxWidgets translation
535 files like it was supposed to, which fixes a few missing translations. This
536 was probably broken by changes in 1.2.8. Reported by Evaristo Quiroga.
538 * (Microsoft Windows version): Drop two options from explorer bindings.
539 "Convert to DXF" and "Convert for hand plotting" have both been supported via
540 aven for a while, and that's a more useful way to access them as you can
541 control what gets exported.
543 Changes in 1.2.34 (2018-03-24):
547 + (Microsoft Windows version): Fix error on startup in the pre-built version
550 + (Microsoft Windows version): Now using wxWidgets 3.0.4 (was 3.0.2).
552 Changes in 1.2.33 (2018-03-22):
556 + Reliably disable scale bar in perspective view. This is supposed to happen
557 (because the scale across the screen varies in perspective view) but
558 actually the scale bar stayed around until an update was forced for another
559 reason. Spotted thanks to Pedro Silva Pinto.
561 + Make "no date"/"not in loop" colour grey. The white was a bit bright and
562 made it harder to see the legs that had colours. The grey now used is
563 within the brightness range of the other colours. Fixes #94, reported by
566 + Fix KML export - exporting both survey legs and station names resulted in a
567 malformed KML file. This bug was introduced in 1.2.30 when support for
568 exporting passages and walls was added. Reported by Erin Lynch in #90.
570 + Consistently use 2 decimal places for altitude in KML output. Some places
571 used 8 decimal places which is appropriate for lat and long, but clearly
572 overkill for an altitude in metres and increases the file size
575 + Right-align bearing widget in print/export dialog. The change to allow the
576 value to wrap round from 360 to 0 in 1.2.27 inadvertently made this control
577 left-aligned (due to incorrect wxWidgets documentation of the default style
580 + (Unix version): Work around wxWidgets bug so that custom cursors work
583 + (Unix version): Update GTK version reporting - report GTK3, and don't
584 bother to report subversions of GTK2 (it seems to be fairly arbitrary
585 which subversions wxWidgets defines constants for).
587 + Update code to work without warnings when using wxWidgets 3.1.0 (the
588 current development version).
590 + Make movie export code compatible with upcoming FFmpeg 3.5 release.
591 It should still work with the older versions that worked before this
592 change. Reported by James Cowgill in https://bugs.debian.org/888334
596 + Warn about 2 digit years. We can't change the assumption that these are
597 19xx without risking breaking existing datasets, but the further we get
598 into this century, the more likely such an assumption is to catch someone
599 out. The warning can easily be quashed by explicitly adding the assumed
602 * The Spanish translation is now up to date once more, thanks to updates from
605 * Merge French translation updates from Jean-Marc.
607 * Fix transposed German Northing and Easting labels. Fixes #95, reported by
610 * Fill in missing translations of "Easting", "Northing", "E" and "N" for
611 Bulgarian, Greek, Hungarian, Polish and Russian based on other existing
614 * Align .pos file headings better with columns of coordinates below for
615 Indonesian and Polish.
617 * Fix handling of the message string "error" before messages loaded. If
618 there's an error loading messages, we need this message to report it.
619 Reported by Martin Sluka.
621 * Fix a few compiler warnings.
623 * img library: Fix extracting leaf survey name for survey title. When there
624 are three or more levels of survey, we were taking everything after the first
625 dot rather than everything after the last dot.
627 * Fix problems with testsuite on macOS:
629 + cavern.tst: Skip "ONELEG" testcase on case-insensitive filing systems
630 - this test isn't meaningful unless the filing system is case-sensitive,
631 but happens to fail if it isn't.
633 + cavern.tst: Workaround limitations of Apple's sed.
635 + aven.tst: Fix not to hang on macOS.
637 + smoke.tst: Remove aven testcases which duplicate those in aven.tst.
639 * Clean up handling of support files in relocatable installs - this is now
640 detected at run time on macOS.
642 * Split out macOS Aven.app creation into a make rule so it can be easily used
643 by the homebrew formula.
647 + Fix when WX_CONFIG not specified - this was giving a confusing error like:
648 ./buildmacosx.sh: line 163: --cc: command not found
650 + Use wxWidgets 3.0.4.
652 * Stop checking wx-config --ldflags as this option was removed in wxWidgets 2.6
653 and we currently require 2.8 or newer.
655 Changes in 1.2.32 (2017-07-08):
659 + Make splays on printouts a darker shade of grey. Reported by Erin Lynch
662 + In export formats which include 3 dimensions (DXF, PLT, GPX, KML, JSON,
663 POS), the value in the Z dimension was negated. Bug introduced by fixes
664 for export of rotated plans and tilted elevations in 1.2.27. Reported by
667 + Ignore viewing angles for export formats which work in 3D. When the
668 rotation and tilt controls are hidden in the export dialog we were still
669 using their values to transform the data, so if you set them with for one
670 export format which support them, then switched to an export format which
671 doesn't, you'd get bogus coordinates in the exported file. Bug probably
672 introduced in 1.2.27 by fixes for exports of rotated plans and tilted
675 + Fix exporting to skencil and Survex .pos formats. When aven's export to
676 .pos was added in 1.2.19, the ordering didn't match up and since then .pos
677 export has produced skencil files and vice versa.
679 + Don't leave terrain on if loading terrain data fails. Previously if you
680 clicked the terrain icon (or via the menu) with no terrain loaded, but no
681 terrain got loaded (e.g. because the survey data lacks an explicit
682 coordinate system, or because the file failed to load, or because you
683 cancelled the dialog) then the terrain icon/menu item was still changed to
686 + Disable texturing while drawing terrain. Previously the terrain got a bit
687 darker when "Textured Walls" were enabled.
689 + Force a refresh when "Textured Walls" are enabled or disabled. Previously
690 the display wouldn't update right away.
694 + Document how to specify fixed point altitude in feet.
696 + Explain why *fix warns about unused fixed points
698 * Building from source now requires a compiler with decent support for C++11.
699 If you're using GCC, then GCC 4.7 should suffice. This should not be an
700 onerous requirement - e.g. Debian wheezy and Ubuntu trusty both have a recent
701 enough GCC. If special options are needed, these should get probed for and
702 automatically. Fixes building 1.2.31 with GCC < 6, reported by Wookey.
704 Changes in 1.2.31 (2017-07-01):
708 + Use superscript 'g' symbol instead of word 'grads' in status bar. This
709 conserves the limited space available, and we already do this in the
710 compass and clino indicators so it's more consistent too.
712 + Show one decimal place on measure line bearing. Pointed out by Benedikt
713 Hallinger on the therion list, though I'm sure this has been asked for
716 + Show gradient of the measuring line when both ends are stations.
718 + Allow selection of text in cavern log window. Selection was disabled in
719 1.2.28 because it seemed you couldn't actually copy selected text to the
720 clipboard, but retesting this now actually works fine for me, both with
721 current git master with the change reverted, and with code just before the
724 + More robust parsing of cavern output (cleanly handle context highlighting
725 which extends beyond the end of the line).
727 + Allow showing duplicate legs as dashed lines or hiding them entirely,
728 with dashed now being the default. Implemented by Patrick Warren.
730 + Also allow "Dashed" for splays and "Faded" for duplicate legs.
732 + Splay legs in surface data are also shown faded.
734 + Check environment variables VISUAL and EDITOR when looking for editor to
735 use when a warning or error is clicked on in the cavern log window. The
736 specified editor may have a GUI or need to run in a terminal, so we have to
737 special-case each editor supported, and that means we can pass extra
738 options needed to position the cursor on the appropriate line/column.
739 Currently these editors are supported: gvim, nvim, vim, gedit, pluma,
740 emacs, nano, jed, kate. Suggested by Wookey.
742 + Fix handling of non-square terrain data files - the X and Y dimensions were
743 swapped. Reported by detrito.
745 + Improve parsing of DEM data with .hdr file. Use documented defaults for
746 more values, and where we only support a subset of values (or a particular
747 value) check for unsupported values in more cases.
749 + When colouring by depth, fix colouring and texturing of polygons which
750 cross depth bands. The previous problems were most obvious with high
751 chambers and long legs down deep pitches, especially in for surveys without
754 + Support for drawing blobs using point sprites was added in 1.2.28,
755 but caching that this worked wasn't hooked up properly so the test to
756 see if this worked would happen at the start of each run. This is now
757 cached as intended which should reduce start up time a little when blobs
758 are drawn in this way.
760 + Fix drawing of crosses with lines. This is a fall-back case which is
761 rarely used as most OpenGL setups will handle a better method, but it was
762 resulting in crosses with a four-pixel square in the centre - now the
763 centre should be a single pixel.
767 + Allow *data with no arguments to reset the current style - useful for
768 entering passage data where there are side passages.
770 + Fix hang processing file without newline at end. This bug was introduced
771 by changes in 1.2.28. Reported by Mark Brown.
773 + (Mac OS X and Microsoft Windows versions): Build with newer version of
774 PROJ library which fixes buggy handling of *fix with lat-long coordinates.
775 Also add a testcase to the testsuite to alert users building for themselves
776 with an affected PROJ version on any platform. Reported by Ross Davidson.
778 + Fix cavern to handle Compass .DAT with no survey team. Previously this
779 resulted in the bogus error: Expecting numeric field, found "FROM"
780 Reported by Erin Lynch.
782 + Handle UTF-8 "BOM" at start of .svx files. Unicode doesn't recommend its
783 use, but Microsoft stuff seems to like to create files with it in, and the
784 error cavern currently reports for such files is very confusing, so it
785 seems best to just handle it. Reported by Rob Eavis.
787 + Change a couple of messages to use double quotes for consistency with all
792 + Now runs a bit faster.
794 + Splays are now carried over the extended survey. The current handling
795 is simplistic, but should do a good enough job to be more useful than
796 discarding splays. The splays at each station are all rotated together
797 based on the bearing between the stations either side of the current one
798 along the first path extended through that station. This nicely handles
799 dead ends and the situation at the top or bottom of a pitch, and should
800 tend to pick an angle close to the passage orientation along a traverse.
801 It's weakest at junctions. Feedback (especially examples which could
802 be handled better) most welcome.
804 * French translation is now up to date again, thanks to Jean-Marc.
806 * Remove erroneous menu shortcut markers from Polish translations.
808 * Fill in some missing translations in several languages by using message
809 translations from therion.
811 * Add note to *fix documentation to clarify the coordinate order with *cs
812 long-lat. Issue raised by Ross Davidson.
814 * Fix errors in documentation of *units: "DEG" should be "DEGS", and
815 "MINUTES" has been supported for ages but wasn't documented. Reported by
818 * Fix a few typos in the documentation.
820 * Fix compilation warning with recent GCC.
822 Changes in 1.2.30 (2016-10-03):
826 + (Microsoft Windows version): Fix crash when trying to print or export
827 (probably introduced in 1.2.28). Reported by Brian Clipstone.
829 + Report error if terrain file contains no terrain data in area of survey.
830 Suggested by detrito.
832 + Errors when writing an export file were reported with the wrong filename
833 - the .3d file, not the filename we were trying to write to.
835 + Export to KML now supports exporting passages, walls and cross-sections.
836 Addresses the remainder of ticket #4.
838 * Add man page for dump3d.
840 Changes in 1.2.29 (2016-09-27):
844 + Fix SVG output with non-ASCII characters (the charset in the SVG file
845 is now set to UTF-8 not ISO-8859-1).
847 + (Microsoft Windows version): Fix error dialog on startup in pre-built
848 version. Reported by Brian Clipstone.
850 * Manual: Add link to TerrainData wiki page. Omission highlighted by Erin
853 * Fix to build without FFmpeg/libav and with older versions, broken by changes
854 in 1.2.28. Reported by James Begley.
856 Changes in 1.2.28 (2016-09-24):
860 + Show the contents of the line after error and warning messages while
861 processing survey data, and indicate the region of the line in many cases
862 in the same style that compilers such as GCC and clang use (using the
863 column number we already have, plus new width information). Based on a
864 patch from Mateusz Golicz.
866 + Add column and width information for many more error and warning messages.
868 + Fix column for "Separator in survey name" warning.
870 + Improve warnings when using a backclino with range 0-180 degrees (reusing
871 the same machinery we already have for a forward clino with range 0-180
876 + Include LRUD in printout/export of extended elevations, broken by
877 improvements to export of tilted elevations in 1.2.27. Reported by Anthony
880 + Name <trk> tags in GPX output, so Garmin GPS units name the imported track
881 usefully. Reported by Anthony Day.
883 + Remember scale from previous print or export operation in the same run of
884 aven. Suggested by Stuart Bennett.
886 + Convert range indication below shown line to a highlight on that region
887 of the line in cavern log window.
889 + Fix colouring of error/warning without column in cavern log window.
891 + Fix click on error/warning without column in cavern log window.
893 + Fix highlight of translations of "error" or "warning" containing non-ASCII
894 characters. This fix for this only works with a Unicode build of
895 wxWidgets, but as of wxWidgets 3.0, all builds are Unicode, so this
896 shouldn't be much of a problem as wxWidgets 2.x is close to obsolete now.
897 Reported by Mateusz Golicz.
899 + Disable selection of text in cavern log window - you can't currently copy
900 it to the clipboard, so until that's implemented it seems better to disable
901 the ability to select it. Reported by Wookey.
903 + Avoid special "1000" scale entry when exporting.
905 + Show 1 page when "One Page" selected.
907 + Reload processed data when restricting view. Fixes failure when
908 restricting view on data just processed via aven. Spotted by Andrew
911 + Don't hide blobs and crosses behind terrain. Reported by Jenny Black.
913 + Fix rendering of crosses using point sprites. The texture being used was
914 misaligned relative to the image used for the visual fidelity check, so the
915 check always failed and point sprites would never be used. Where point
916 sprites are supported, they're probably the fastest option - on my netbook
917 this change improves FPS by ~6 fold when displaying crosses for a large
920 + Support drawing blobs using point sprites. About 5 times faster than using
923 + Recheck how best to draw crosses and blobs on the first run after Survex
924 is upgraded (or downgraded) as the rendering code may have changed (we
925 already recheck when the OpenGL hardware or driver changes).
927 + Change "MPEG" export to be MPEG4 (.mp4) rather than MPEG1 (.mpg).
928 MPEG4 produces smaller output of higher quality, and should be widely
929 supported these days. And I can't get the MPEG1 output to work without
930 buffer underflows, resulting in a file which doesn't play without
933 + Add OGG video to the list of formats - it's more compact than the others
934 we currently list, though slower to write.
936 + Fix export to movie formats for which libav/FFmpeg needs to seek the file
937 being written. This was broken by changes in 1.2.27.
939 + Overhaul movie export for the current FFmpeg API, fixing deprecation
940 warnings when building against a recent version.
942 + (Microsoft Windows version): Fix corrupted exported movie files. 1.2.27
943 changed the movie export code to allow writing to files with non-ASCII
944 characters in the names, but the new code failed to open the file in binary
945 mode, leading to corrupt output. Fixes #81, reported by Erin Lynch.
947 * (Microsoft Windows version): Pre-built version now uses FFmpeg 3.1.3 for
950 * (Mac OS X version): Pre-built version now uses FFmpeg 3.1.3 for movie
953 * Fix to build without FFmpeg/libav, broken by changes in 1.2.27. Reported by
956 * The Polish translation is now very close to being complete, thanks to a
957 substantial update from Mateusz Golicz.
959 * Merge catalan translation updates from Adolfo Jayme.
961 * (Microsoft Windows version): Map LANG_CHINESE to zh_CN not zh so Chinese
962 messages get used automatically.
964 * cavern.tst: Remove random : from after ] - dash ignores the extra character,
965 but it causes this test to fail if /bin/sh is a different shell (e.g. bash).
967 * cavern.tst: Add expected output for more testcases.
969 * Remove unwanted execute bit from some testcase data.
971 * Use https for more URLs which support it.
973 Changes in 1.2.27 (2016-06-06):
977 + Right click on a survey in the survey tree now gives a pop-up menu
978 with "Hide others", which restricts the view to just that survey
979 and any subsurveys. Right click on the root of the survey tree
980 gives a menu with "Show all" to undo any restriction in effect.
981 (Currently these are implemented by reloading the file and using
982 the same machinery as the --survey= command line option, but that will
983 probably change in the future).
985 + If there's a sub-survey restriction (from the --survey= command line
986 option or the new UI described above) it is now shown in brackets after
987 the survey tree root.
989 + When reloading a survey, preserve the current view position (previously
990 the view was recentred).
992 + When reloading a survey, actually preserve the current scale factor
993 (this was meant to happen, but the adjustment was applied in the
996 + New "File->Extended Elevation..." menu item provides a way to generate
997 extended elevations for simple cases without having to use the command
998 line. Suggested by Fleur Loveridge.
1000 + Don't process key presses if accompanied by an unexpected modifier key.
1001 In particular, this means that aven no longer interferes with Alt+<function
1002 key> (which is typically handled by the desktop) and Alt+<letter> (which is
1003 typically a menu short cut). Reported by Владимир Георгиев.
1005 + Reduce file loading time by ~5%. The station name compare function was
1006 something of a hot spot, and optimising it yielded a nice improvement.
1008 + Allow splay legs to be disabled in when printing and exporting. Mostly
1011 + SVG export now shows splay legs thinner and in grey. See #60.
1013 + Fix export of rotated plans and tilted elevations - previously plans were
1014 always aligned with North up, and elevations which weren't exactly side on
1015 were exported as plans. Reported by Stuart Bennett.
1017 + Fix offset bounding box for exported elevations.
1019 + In print/export dialog the bearing value now wraps if you scroll up past
1022 + Fix greying out of LRUD-based controls in the print/export dialog when the
1023 view is tilted (i.e. not plan or elevation). This stopped working in
1024 1.2.18 when the pan and tilt spin controls were changed from integer- to
1027 + Printouts now show LRUD as pale grey arrows from the station they are
1028 measured from. Based on patch from Michael Sargent. Closes #65.
1030 + Take LRUD into account for printout size. Fixes #72, reported by Erin
1033 + Update movie export code to work with latest version of FFmpeg.
1035 + Make "Show Log" a toggle, so you can click on the button to take a look at
1036 the log, and a second click returns you to the survey view.
1038 + (Microsoft Windows version): Open the font file in binary mode - it looks
1039 like we were lucky and the font file (or at least its current version)
1040 would have loaded OK in text mode despite being binary data.
1042 + (Microsoft Windows version): Exporting to files with non-ASCII filenames
1047 + Allow tape or backtape to be omitted. Reported by Erin Lynch.
1049 + Grid convergence is now corrected for when using automatically
1050 calculated declinations (*declination auto <X> <Y> <Z>). Requested
1051 by Mateusz Golicz on the mailing list.
1053 + Clear any cached calculated declination upon another *declination auto
1054 with different coordinates. Previously if the date stayed the same,
1055 a previously cached declination for the old coordinates was used.
1057 + Fix check for end of version number array in *required. We would check up
1058 to 12 version components, the last 9 being bogus. In practice, *require is
1059 only likely to be used with up to three components, so this wouldn't be an
1062 + *begin with an invalid prefix could cause a crash in some cases. Fixed
1063 by patch from Colin Watson.
1065 + Report column locations for errors to do with readings.
1067 * Merge translation updates from Jean-Marc.
1069 * img library: Better document which members can be set when writing.
1070 Highlighted by email query about use of img API from Владимир Георгиев.
1072 * Document how *declination interacts with *calibrate declination if both are
1073 used in the same dataset.
1075 * doc/3dformat.htm: Update details of how changes to the current label buffer
1076 are encoded to reflect changes in v8. Reported by Angus Sawyer.
1078 * Use docbook2man instead of docbook-to-man to generated Unix man pages
1079 from SGML source. The latter seems to be no longer actively maintained, and
1080 docbook2man now does a similarly good job.
1082 * Use https for survex.com links, and for other sites which support it.
1084 Changes in 1.2.26 (2016-01-07):
1088 + (Microsoft Windows version): Fix to be able to process .svx files with
1091 * (Microsoft Windows version): Simplify upgrading process with innosetup
1092 installer - if Survex is already installed, we now just install to the same
1093 location and use the same start menu folder.
1095 * (Linux version): survex.spec: Update for filetype metadata change in 1.2.25.
1096 Fixes #79, reported by James Begley.
1098 * (Linux version): survex.spec: Fix to work with RPM 4.13. Fixes #79, reported
1101 Changes in 1.2.25 (2016-01-05):
1105 + Drop broken code which attempts to fix 2D pitches. Fixes #73, reported by
1106 Erin Lynch. #76 tracks the issue the removed code was trying (but failing)
1109 + When animating, don't try to update station info based on mouse movement
1110 over the survey tree.
1112 + Further improve code to handle cavern subprocess in aven.
1114 + Fix jump to error for filenames containing colons when the error location
1115 doesn't have a column number. Bug noted by Jenny Black.
1117 + If we encounter bad UTF-8 in cavern output, replace it with a red and white
1118 ? in a diamond (previously we gave up showing output at the first bad
1119 sequence). This can happen if you process a .svx file which isn't UTF-8
1122 + (Unix version): Don't try to set the terminal window title when opening an
1123 editor from the cavern log window - gnome-terminal no longer supports this,
1124 and there doesn't seem to be a portable option for specifying the title for
1125 terminals which do still support this.
1127 + (Microsoft Windows version): Also quote for cmd.exe so that paths with
1128 spaces in work reliably. Reported by Marco Cotto.
1132 + Improve error for mismatched fore/back-sight plumbs, reported by Andy
1135 + Fix to use correct sd for backcompass. We were using zero instead, the
1136 most obvious effect of which was that the threshold for warning about
1137 differing COMPASS and BACKCOMPASS was about 71% of what it should have
1138 been, so we were warning in more cases than we should have been.
1140 + Implement support for specifying a length on backsights - if you're using
1141 something like a disto-x, you'll get a distance reading for the backsight
1142 too. Fixes #71, reported by Erin Lynch.
1144 + Make line counting more robust to mixed line ends. Noticed in example file
1145 from Pete Smart (see #69).
1147 * extend: New --show-breaks option which adds a leg flagged as surface survey
1148 between each points at which a loop has been broken. Suggested by Jenny
1151 * (Unix version): Update filetype metadata to work with modern desktops.
1153 * Fix incorrect reporting of errors reading and writing processed survey data.
1154 Since 1.2.8, the error strings corresponding to IMG_CANTOPENOUT,
1155 IMG_BADFORMAT and IMG_DIRECTORY have been mixed up (this doesn't affect
1156 external programs using the img library, only Survex). Reported by Jenny
1159 * Add missing options to extend man page and --help output. Noted by Jenny
1162 * Document Document Ctrl+cursor keys for rotating and tilting in aven man page.
1164 * Fix broken SGML markup in manual.
1166 * Fix typo in manual reported by Jenny Black.
1168 * Update vim syntax file for newer commands, etc.
1170 * Minor translation updates. Thanks to Piotr Strębski and Jean-Marc.
1172 * Fix to compile with FFmpeg 2.9. Reported by Andreas Cadhalpun in
1173 https://bugs.debian.org/803863
1175 * Stop maintaining ChangeLog files. They make merging patches harder, and stop
1176 'git cherry-pick' from working as it should. The git repo history should be
1177 sufficient for complying with GPLv2 2(a).
1179 * (Microsoft Windows version): The installer requires admin privileges on Vista
1180 and later and OS versions older than Vista are past end of life, so drop code
1181 which tries to set up the registry differently depending if we have admin
1184 Changes in 1.2.24 (2015-09-23):
1188 + (Microsoft Windows version): Fix the cavern log window. Reported by Brian
1191 + (Microsoft Windows version): Add workaround to avoid breakage in Therion.
1192 Reported by Jenny Black.
1194 + If wx was built with thread support, aven now runs cavern from a separate
1195 thread, which works much better under wxMSW (where we can't use select),
1196 and also seems a bit smoother on Linux.
1198 + Fix handling of encoding of filenames when the operating system has no
1199 locale installed corresponding to the language selected for Survex's
1202 + Undo accidentally committed debugging code which was sending message to
1203 the terminal in 1.2.23.
1205 * (Linux version): configure now looks first for wx-config-3.0, which Fedora's
1206 wx3 packages have. Reported by James Begley.
1208 * Indonesian translation fully up to date again.
1210 * Manual: Document anonymous stations, based on the text from NEWS. Reported
1213 Changes in 1.2.23 (2015-09-06):
1217 + Updating the cavern log window is now much smoother, especially on slower
1220 + Show "busy" mouse cursor while processing survey data.
1222 + Fix an assertion if you try to start processing a survex file while one is
1223 already being processed.
1225 + Processing a .svx file with an error now still adds it to the file history.
1226 Reported by Martin Green.
1228 + Fix the orientation of the starting end of tubes.
1232 + New *ref command to allow specifying an external reference (e.g. where to
1233 find the original survey notes).
1235 + Drop support for showing percentage progress in cavern. It's confusing in
1236 a multiple-file dataset as it shows progress in the current file so jumps
1237 around. It also slows down processing, and on a slow machine you'd don't
1238 want that, while on a fast machine processing isn't slow enough for the
1239 progress display to be useful.
1241 * French translation is now completely up to date, thanks to Michel Bovey.
1243 * Bundle proj's EPSG and ESRI code lists in the installers for MS Windows and
1244 OS X so that things like "*cs EPSG:29903" work. Reported by Graham Mullan.
1246 * (Microsoft Windows version): Process survey data with aven rather than
1249 * (Microsoft Windows version): Installer built with InnoSetup 5.5.6 (recent
1250 releases have been built with 5.5.3) to see if that solves Ray Duffy's
1251 reported issue with not having file associations for .svx files created.
1253 Changes in 1.2.22 (2015-08-17):
1257 + Ensure that the window has a depth buffer. Whether it does by default
1258 seems to vary depending on OS and maybe graphics card. Fixes #55 (terrain
1259 is no longer visible through itself), and also the rendering of passage
1260 tubes. Thanks to Martin Green for pointing me in the right direction for
1265 + Fix *declination with an angle to actually work.
1267 + Fix assertion if we try to identify a hanging survey by an anonymous
1270 + Improve errors for invalid survey names in *begin, *end, *equate and
1273 Changes in 1.2.21 (2015-07-28):
1277 + Fix exporting to KML and other text-based formats to always use "." for the
1278 decimal separator - previously "," would be used when the user's locale
1279 specified this for the decimal separator. Reported by Jan Schorn.
1281 + Implement exporting of survey legs in KML format.
1283 + Put "paddle" placemarker icons on stations in exported KML files, using the
1284 same colour coding for entrances, fixed points and exported points as aven
1287 + Remove the "Coordinate projection" field from the print dialog, as it isn't
1288 relevant there. Reported by Wookey.
1290 + Fix the initial scale for small caves (since 1.2.18 the initial scale has
1291 been too small). Reported by Wookey.
1293 + Don't rescale if the same file is reloaded, but adjust the volume diameter
1296 + Use wxGetenv() to read the SURVEXEDITOR variable, so we can accept Unicode
1301 + Fix coordinate systems using latitude and longitude - PROJ.4 wants these in
1302 radians, but we were passing degrees, which would generally cause the
1303 conversion to the output coordinate system to fail. Reported by Wookey.
1305 + Fix *fix with standard deviations when *cs is in use, give an error for use
1306 of *fix with standard deviations before *cs.
1308 + Add new *declination command with support for setting the declination
1309 automatically from the IGRF model based on the survey date. Thanks to the
1310 Therion developers for the IGRF support code, which we're reusing.
1311 Fixes #54, reported by Wookey.
1313 + Allow the units for the zero error to be specified, making it easier to
1314 specify calibration with a scale if you measure the zero error externally
1315 (rather than using the instrument itself). Fixes #61, reported by Andrew
1318 + Report the error from PROJ when coordinate conversion fails as part of the
1319 actual error rather than on a separate line.
1321 + Fix use after free after *solve. This only occurs if a leg between the two
1322 exact same stations appears right before and right after the *solve, which
1323 is unlikely in real data, but the testsuite has an instance of this. This
1324 was introduced by the repeat leg averaging added in 1.2.17.
1326 + Fix small memory leak when solving network. This doesn't really matter
1327 when solving at the end of processing as cavern will exit after that, but
1328 if *solve is used we continue processing after solving.
1330 * Remove compatibility handling for specifying a country variant of a language
1331 in SURVEXLANG using "-" with a lower case country code (e.g. "en-us") - we
1332 changed to the standard "en_US" way back in 2001. This code was mangling
1333 character sets with a "-" in, and is no longer useful.
1335 * Ignore any "@<something>" modifier in the language code.
1337 * Improve documentation of magnetic declination handling, and cover the new
1338 "*DECLINATION" command.
1340 * Document aven's command line options in the manual and its man page.
1341 Reported by Jenny Black.
1343 * Point to '*case' and '*truncate' from the 'SEE ALSO' sections of each other's
1346 * Remove references to SpeleoGen from the documentation - it hasn't been
1347 updated for many years, and can't read recent versions of the .3d format.
1349 * Strip documentation references to obsolete versions of MS Windows.
1351 * doc/HACKING.htm: Update list of debian packages to install to build from git.
1353 Changes in 1.2.20 (2015-06-26):
1357 + When printing, use the top margin rather than the right margin to calculate
1358 the height of the printable area. In practice, the two values seem to be
1359 the same or very similar by default.
1361 + Avoid assertion if the about dialog image fails to load. Reported by Phil
1364 + Optimise the size of the about dialog images.
1366 + Add support for reading terrain data which isn't in a .zip file.
1368 + Force a refresh after loading terrain data so that it gets displayed right
1371 + Make checks for terrain data extensions in zip files case insensitive.
1373 + If reading terrain data fails, always report an error and never try to
1376 * cavern: Allow clino readings in diving style data, suggested by Andrew
1377 Atkinson. Currently these readings are ignored, but a future version will
1378 check that they're consistent with the angle given by the depth gauge and
1379 tape, and perform suitable averaging.
1381 * Remove lingering traces of svxedit.
1383 * configure: Fix to allow compiling without libav/ffmpeg, as was possible
1386 * (Unix version): Install the filetype and aven application icons under
1387 /usr/share/icons/hicolor, which is where they're expected to be these days.
1389 * (Unix version): Add %f to Exec in survex-aven.desktop.
1391 * (Mac OS X version): Remove useless extra copy of about box images from OS X
1394 * (Mac OS X version): Only ship one copy of each of the translations.
1396 * (Mac OS X version): Reduce the size of the aven binary by disabling a load of
1397 libav features we don't use.
1399 * (Microsoft Windows version): Reduce the size of the aven binary by disabling
1400 a load of libav features we don't use.
1402 * (Microsoft Windows version): Update message files to fix a missing Chinese
1403 message in the installer.
1405 Changes in 1.2.19 (2015-06-18):
1409 + Fix exporting to GPX, KML and HPGL, which all failed to write the header to
1410 the exported file in 1.2.18.
1412 + Add exporting to Survex .pos format.
1414 + If the measuring line isn't currently active, pressing "Escape" will now
1415 exit full screen mode.
1417 + (Mac OS X version): Change the shortcut for full screen mode to be the
1418 standard Ctrl+Command+F (rather than Shift+Command+F which we have been
1421 + (Mac OS X version): When we centre the view on the station this can
1422 generate a mouse move event, so clear the variable which says we are
1423 dragging before we process a left click on a station. This avoids random
1424 rotations of the survey when clicking on a station, reported in #47 by Hugh
1427 + (Mac OS X version): Force use of a non-native toolbar to stop the toolbar
1428 icons from being rescaled and looking fuzzy.
1430 + (Mac OS X version): Remove code added in 1.2.18 which tries to set stop the
1431 toolbar icons from being rescaled, but which requires an unreleased version
1432 of wxWidgets, had a typo in, and doesn't actually seem to work anyway.
1434 + (Mac OS X version): Drop out of full screen mode if the mouse is mode to
1435 the top of the screen, since we can't seem to display the menu bar in this
1436 case like we do on other platforms.
1438 + (Mac OS X version): Enable aven's movie export feature.
1440 + (Mac OS X version): Enable wxDisplay when building wxWidgets to better
1441 support multi-monitor setups.
1443 + (Mac OS X version): Silence warning visible when aven is run from a
1444 terminal about a missing CFBundleTypeRole.
1446 + When reading terrain data from a .zip file, report an error if the .zip
1447 file is bad, or if it doesn't contain any terrain data we recognise.
1449 + Tweak error message in terrain reading code to distinguish two failure
1452 + Add viewing angles and scale to footer, and shorten some of the other items
1453 to make room for this extra information. (Fixes ticket #52, reported by
1456 + If the footer is wider than the printout width, scale down the font used
1457 so that it exactly fits; if the footer is narrower, than space out the
1458 items in in so it uses the full width.
1460 + If the saved size for aven's window exceeds the current display size
1461 (mostly likely because we're now plugged into a smaller monitor), then
1462 reduce the size of the window to fit the display. If the saved size is <
1463 (480x320), increase it to at least that, as aven isn't usable in a smaller
1466 + Remove crude bodge which tries to pick a nicer initial window size when
1467 using wxWidgets without wxDisplay on a multi-monitor setup - aven now opens
1468 with the same size window it had when it was closed, so the initial size is
1469 only relevant on the first ever run.
1471 * Assorted translation updates. Notably Indonesian is at 100% again.
1473 * Stop trying to catch and report signals. The only real reason to do it is so
1474 we can say "Bug in program detected! Please report this to the authors"
1475 before we exit, but when the program crashes that's pretty obvious. In aven
1476 we try to pop up a message box for this message, which may fail due to
1477 whatever caused the signal, while with the command line tools there's no
1478 great benefit over just letting the shell report the signal.
1480 * Use pkg-config to probe for libav and proj, which sorts out the correct flags
1481 for building on OS X against a static install of libav.
1483 Changes in 1.2.18 (2015-06-03):
1487 + Add support for reading terrain data (from a zip file containing either an
1488 SRTM .hgt file, or an ESRI .bil file and associated metadata files), and
1489 rendering it as a transparent surface.
1491 + Remove actions from 'Orientation' and 'Rotation' menus which you wouldn't
1492 sanely want to perform from the menu.
1494 + Create a "Colour by" submenu of the "View" menu to house the various
1497 + Add "Colour by Gradient" and "Colour by Length".
1499 + Make the button to dismiss the "About" dialog "OK" rather than "Close",
1500 which seems more logical, and also allows the dialog to be closed by
1503 + Destroy any existing clipping region before we write the page footer.
1504 Hopefully solves ticket #52, reported by Erin Lynch.
1506 + Don't round bearing and tilt angles to integers when printing and
1509 + Add passage export for EPS format. (Partly addresses ticket #4)
1511 + Add JSON export. This should be regarded as experimental, and the format
1512 is quite likely to change.
1514 + Pressing F6 now toggles the display of rendering stats, currently FPS
1515 (Frames Per Second) and the number of triangles in the terrain mesh.
1517 + Add a menu item and toolbar button to show the cavern log window if the
1518 currently shown survey data was processed by aven. Reported by Hugh St
1519 Lawrence in #47, and by Dave Clucas and others previously on the list.
1521 + Add "Save Log" button to Aven's cavern log window.
1523 + In cavern log window, highlight "error" markers in red and "warning"
1526 + Rework code to read cavern's output. In particular, we no longer mix
1527 buffered and non-buffered system calls.
1529 + Aven's support for reading colours and font sizes for printouts from
1530 print.ini has never worked - the contents of the ini files are ignored due
1531 to a bug which has been there since the code was added in 2005 - but nobody
1532 has ever complained. So just strip out that code entirely - we should
1533 support setting the colours and font sizes, but a GUI interface for setting
1534 them would be better.
1536 + Fix to compile with a Unicode build of wxWidgets 2.8. Reported by Bill
1539 + Take the width of the messages used above the compass and clino into
1540 account when calculating how much space to allow for them - now the labels
1541 won't overlap or be cut off in translations where they are long.
1543 + (Mac OS X version): Attempt to address the size of the toolbar icons.
1547 + Reject *fix with SDs which aren't all positive. (fixes#2, reported by
1550 + Use the currently set units when outputting measurements in warnings,
1551 errors, and the stats at the end of the run. Requested by Bill Gee.
1553 + Include column number when a *include file isn't found.
1555 + Show 'error' in front of error messages, like we show 'warning' in front of
1556 warnings. Fixes #48, reported by Wookey.
1558 + Increase the threshold for warning that fore and back measurements differ
1559 from 2 SDs to 3 SDs.
1561 * findentrances: If the 3d file specifies the coordinate system, use it.
1563 * svxedit: Remove svxedit - while an editor with built-in knowledge of survex
1564 would be nice to have, svxedit doesn't really offer that, and it looks ugly
1565 in a modern desktop.
1567 * If we run out of memory while reading a processed survey data file, include
1568 the filename in the error message.
1570 * Many translation updates - notably Indonesian and Russian are now the two
1571 most complete translations.
1573 * (Microsoft Windows version): Add code page 1252 mappings for fancy quotes.
1575 * Transliterate gradient and infinity symbols if the current character set
1578 * Add SVG version of .plt icon.
1582 + Add complete list of quantities you can set SDs for. Thanks for Wookey for
1583 highlighting that the previous list was incomplete.
1585 + Document averaging of a group of repeated readings.
1587 + Add a link to the sample data from the manual.
1589 + Remove references to contact addresses which are no longer there. Remove
1590 offer to post people floppies, and references to a CD image which isn't
1591 available for download.
1593 * Remove non-breaking spaces from the diffpos and extend manual pages, as they
1594 actually make the output formatting worse (presumably these used to work
1595 around a since-fixed bug in one of the docbook processing tools).
1597 * doc/TODO.htm: Update.
1599 * Fix to compile without warnings with 'g++ --std=gnu++11'.
1601 Changes in 1.2.17 (2015-02-24):
1605 + Update INSTALL file with current status.
1607 + Aven.app now has a custom icon.
1609 + Add icons for all the filetypes supported.
1611 + Add Finder actions for .svx, .3d, .plt and .pos files.
1613 + aven: Hide the status bar and tool bar in Full Screen mode, as wx doesn't
1614 currently do this for us.
1616 + aven: Fix short-cut for toggling Full Screen mode.
1618 + aven: Make "About" menu item appear.
1620 + aven: Fix "Close" button in about dialog.
1622 + aven: Make custom cursors black with a white outline to match the standard
1625 + svxedit: Now wrapped up in an application bundle as svxedit.app. It
1626 still doesn't really work like a standard app though - e.g. you can't load
1627 files from Finder (instead run svxedit.app and use File->Open), the font
1628 size of most menu items is wrong, the icon for the app is the wish icon
1629 rather than the svxedit icon, shortcuts use Ctrl not the Cmd key, and
1630 probably more. I'd probably recommend using another editor (OS X comes
1631 with TextEdit.app for example).
1633 + The documentation is now in a "Docs" directory alongside the apps, rather
1634 than in the rather less obvious "share/doc/survex" directory.
1636 + Default to building for x86_64, since all modern Macs are 64 bit.
1638 + Disable use of liblzma when building wxWidgets for OS X, which was
1639 preventing the build from working on OS X 10.6.8.
1641 + Download wx sources from SF via redirecting link. Thanks to David A.
1644 + buildmacosx.sh: Handle the mount point for the disk image containing a
1647 + Link with a static build of PROJ for doing coordinate system conversions.
1649 + Build wx with --disable-webview to avoid a compilation failure on OS X
1652 + Use wx-config --cc and --cxx to get the compilers to use for building
1653 everything else, as wx adds options to them which otherwise cause linking
1656 + The diskimage (.dmg) file is now compressed with bzip2, which gives a
1657 smaller download. This means OS X 10.4 is required, but we probably
1658 already need at least 10.5 because that's the minimum version which the
1659 wxWidgets build supports by default.
1661 + Remove unused files and copies of files from the diskimage.
1663 * cavern: If the same leg is repeated consecutively, average the readings and
1664 treat as a single leg.
1666 * dump3d: Report SEPARATOR used by the file being read.
1668 * aven.svg: Fix visual glitch in SVG icon for aven. Noted by David A. Riggs.
1672 + Greatly reduce flicker when mouse is moved to the top of the screen in full
1673 screen mode and the menu bar reappears.
1675 + For export formats where scaling is supporting, aven now actually uses the
1676 scale specified in the export dialog (previously it ignored this and used
1679 + Reimplement animation so that it's based on angular change per unit of
1680 elapsed time, rather than averaging the time take for the last two scene
1681 redraws. This gives smoother animation in the face of variable load and
1682 scene redraw time, and should be more consistent between platforms.
1684 + Switching to a point of the compass during auto-rotation now jumps straight
1685 there rather than the two animations fighting.
1687 + Reduce the maximum auto-rotation speed, as the previous limit was uselessly
1690 + Disable stepping the rotation angle when animating (previously we only did
1693 + Speed up start-up a bit - rather than loading icons from individual PNG
1694 files on disk, compile them into the aven binary.
1696 * (Unix version): Add "MimeType" field to desktop files so that file
1697 associations work out of the box with modern desktop environments.
1699 * Add start of Hungarian translation from Imre Balogh.
1701 * Merge in many updates to the Russian translation from "vsuhachev".
1703 * Assorted minor updates to other translations.
1705 * Create scalable (SVG) versions of file type icons.
1707 * doc/manual.sgml: Remove $Id and $Date markers, as they don't get expanded now
1710 * tests/: Improve test coverage in a few places:
1712 + Extend tests of fore and back sights to test calibration of the back
1715 + Test "Can't calibrate angular and length quantities together" error.
1717 + Check that "*set names ." works when "." is also the decimal point.
1719 Changes in 1.2.16 (2014-10-17):
1721 * aven: Add KML export (stations only currently).
1723 * aven: Allow measuring line to measure from anonymous stations. (Fixes #44)
1725 * aven: Fix corrupted names in exported files.
1727 * aven: Fix error log window under wxWidgets >= 2.9 to include the system
1728 information before the first log message like it does under wxWidgets 2.8.
1730 * cavern: Add support for "*cs JTSK" and "*cs JTSK03".
1732 * tests/: Improve test coverage.
1734 * Translation updates for many languages, plus the start of translations to
1737 * Fix to build against wxWidgets 3.0 built with assertions disabled. Reported
1740 * Fix warnings when compiling with clang (which is the default compiler on
1741 Mac OS X). Reported by Martin Sluka.
1743 Changes in 1.2.15 (2014-08-14):
1745 * cavern: The *cs command now also supports "long-lat", "s-merc" (for "Web
1746 Mercator"), EPSG and ESRI codes, "eur79z30", "ijtsk" and "ijtsk03". This
1747 means that we now support all the coordinates systems which Therion does,
1748 except for a few which don't have X=East and Y=North. The documentation
1749 for *cs has also been improved.
1751 * aven: We no longer persist full screen mode between runs - it's not a
1752 standard behaviour of desktop programs, and it's too easy to go into full
1753 screen mode from the menu and then not be able to get out again because you
1754 don't know the required key shortcut. (ticket#39)
1756 * aven: When in full screen mode, moving the mouse to the top of the screen now
1757 makes the menu bar appear. This provides a non-shortcut way out of full
1758 screen mode, as well as making it easier to perform other operations while in
1759 full screen mode. The current implementation gives an annoyingly flickery
1760 transition, but hopefully we can improve this in future. (ticket#39)
1762 * (MacOS X version): If built with wxWidgets >= 3.1.0 (which is still in
1763 development), we now call EnableFullScreenView() which improves the full
1764 screen mode experience on OS X 10.7 and later.
1766 * img library: Improve documentation for img_ERROR_INFO.
1768 * tests/: Ship some missing .out files and compare.tst.
1770 * tests/: cavern.tst testcase back2 is now actually used. Fix a bug in this
1771 testcase, and extend it to cover a variant of the situation reported as a bug
1772 in therion by Bill Gee to the therion list.
1774 * (Linux version) survex.spec: Add run-time requirement on proj and proj-epsg
1775 for the survex package and on tk for the svxedit package.
1777 Changes in 1.2.14 (2014-07-05):
1779 * img library: Add ability to store a PROJ4 string describing the coordinate
1780 system in use in 3d v8 files.
1782 * aven: If the 3d file specifies a coordinate system, then use it for exporting
1783 to formats which need to know (currently GPX). If the input file doesn't
1784 specify the coordinate system, allow the user to enter a PROJ4 string in the
1787 * aven: You can now quickly zoom to a particular area by holding down the
1788 "Shift" key and dragging with the left mouse button to create a rectangular
1789 "rubber band box" around the area you wish to zoom to. If you release the
1790 "Shift" key while still dragging, the box is centred on the start point
1791 rather than having one corner there.
1793 * aven: Fix exporting of passage tubes in elevations and extended elevations
1794 - previously up and down were getting drawn across the page!
1796 * aven: Fix "Cancel" to work on the print/export dialog, broken by changes in
1797 1.2.13. (Reported by Brian Clipstone)
1799 * aven: Fix the conditions on which the menu item "Cancel measuring line" is
1800 enabled - previously it was hard to actually cancel it via the menu.
1801 Reported by Hugh St Lawrence.
1803 * aven: Fix wx assertion failures when showing hit test debug view on platforms
1804 such as 64-bit Linux.
1806 * aven: When viewing from above, show "Plan" above the "clino" which indicates
1807 the tilt angle (instead of "Elevation -90°").
1809 * aven: The extended font data now loads faster, and also uses less memory on
1812 * aven: Dragging the vertical divider between the side panel and the 3D view
1813 now only updates when you finish the drag, as redrawing continuously just
1814 looks clunky except on an ultra-fast machine.
1816 * aven: (German translation) Abbreviate "Blickrichtung" so it doesn't overfill
1817 the space available in the aven UI.
1819 * cavern: Add a *cs command to allow setting the coordinate system for *fix
1820 commands, and the coordinate system used for processed survey data. The
1821 latter is now stored in 3d v8 format files.
1823 * cavern: Add support for 'L' flag (exclude from length) in Compass .dat files
1824 and handle it in the same way as the "DUPLICATE" flag in .svx files.
1826 * cavern: If there's more than one *fix command with coordinates, still
1827 actually fix the second and subsequent ones, to avoid triggering bogus errors
1828 about unconnected surveys.
1830 * cavern: If there's more than one *fix command with coordinates, report the
1831 station name of the previous one, plus the file and line number where it was.
1833 * cavern: Fix handling of the rather contrived case of *fix with no coordinates
1834 followed by *solve and then another *fix with no coordinates not to access
1837 * dump3d: Report any specified coordinate system.
1839 * doc/3dformat.htm: Update to document how the coordinate system is stored.
1841 * (Microsoft Windows version): Include dump3d in the installer.
1843 * Fix a compiler warning.
1845 * Improve test coverage.
1847 Changes in 1.2.13 (2014-05-15):
1849 * aven: Fix --print option to wait for printing to happen before exiting
1850 (previously it would exit right after opening the print dialog, so you
1851 couldn't actually print anything out using it).
1853 * aven: Increase the threshold for how close the pointer needs to be to a
1854 station from 5 pixels to 7 to try to help touchscreen users. Reported by
1857 * aven: Add "fat finger" mode, toggled by pressing F2, to allow investigating
1858 if increasing the minimum pointer to station threshold helps Hugh's problems
1859 with using aven on a touch screen device.
1861 * aven: The measuring line was unable to see stations which had just been
1862 revealed by toggling surface or underground legs on - this is now fixed.
1864 * aven: Add "hit test grid debug" mode, which shows the hit test grid and how
1865 many entries are in each box (toggled by F3).
1867 * aven: Pressing F4 now allows the user to toggle wxWidgets assertion messages
1870 * aven: Create the empty hit-test grid data structure lazily, to reduce start
1873 * cavern: Improve messages which talk about "tags" and/or "prefixes" in *begin
1874 and *end commands to instead talk about "survey names".
1876 * cavern: For ages cavern has warned if you reentered a survey, but this
1877 warning was suppressed if it occurred at the same line of the same file as
1878 the survey was first entered, but this can only happen if you include the
1879 same survey file more than once, which isn't a sensible thing to do for a
1880 file with actual survey data in (you might reasonably do it to set up survey
1881 grade details or something like that). The warning is now given in this
1884 * cavern: After 5 warnings about reentering a survey we give up warning about
1885 it, but we used to keep reporting where the survey was originally entered -
1886 this secondary diagnostic message is now silenced when the main message is.
1888 * (Microsoft Windows version): Compile C code with optimisation on.
1890 * Add the start of a Russian translation, with messages take from therion.
1892 * Minor translation updates to French.
1894 * Fix compiler warning from GCC.
1896 * Testsuite improvements:
1898 + Test that "..." anon station works.
1900 + cavern.tst: Check number of errors returned by all testcases which should
1901 fail and give an error count.
1903 + cavern.tst: Fix to actually fully test everything when builddir != srcdir.
1905 Changes in 1.2.12 (2014-04-14):
1907 * aven: Fix measuring line to show change in altitude rather than altitude
1908 itself (accidentally broken by changes in 1.2.11). Reported by Brian
1911 * aven: Fix printing when built with wxWidgets 3.0.
1913 * aven: Several visual improvements to printouts:
1915 + Move the numbers below the scale bar down a little so that they don't
1916 overlap the scale bar ticks.
1918 + Set the clipping region after we draw the page border and info box to avoid
1919 clipping the border in print preview.
1921 + Tidy up the appearance of the compass and elevation arrow.
1923 * aven: Fix to build with libav 10. Reported by Moritz Muehlenhoff in
1924 <http://bugs.debian.org/739332>.
1926 * aven: Fix to build with older libav where avcodec_free_frame() isn't
1929 * (Linux version) survex.spec: Update spec file used for building RPM packages.
1931 * (Unix version): Add "Keywords:" entry to .desktop files.
1933 * (Unix version): Enable large file support, mostly to support filing systems
1934 which return 64 bit inode values, such as CIFS mounts.
1936 * (Microsoft Windows version): Only allow "A-Z" or "a-z" for driver letters,
1937 rather than any character which is a letter in the current locale.
1939 * Various translation updates.
1941 Changes in 1.2.11 (2014-01-28):
1943 * aven: Fix wxWidgets assertion when double clicking on an anonymous station.
1944 Reported by Kevin Dixon.
1946 * aven: Embed the font data for the first 256 Unicode characters for use in the
1947 survey pane into the compiled aven binary to reduce start up overhead. Any
1948 additional characters needed are loaded from a data file only if/when a
1949 character >= U+100 is actually needed (as before).
1951 * aven: Fix display of Unicode characters above 256 when there's a character
1952 <= 256 earlier in the same string.
1954 * aven: Use the actual width of Unicode characters above 256 rather than
1955 assuming they are 16 pixels wide.
1957 * aven: If full screen, don't show the side panel when a new file is opened
1960 * aven: Don't give an assertion failure when showing passages for a cave with
1961 no vertical extent. Reported by Jonny Prouty.
1963 * aven: Change terminology in print dialog - say "legend" instead of "info
1966 * aven: Add option to show the tilt angle as a percentage gradient.
1968 * aven: Show the units (degrees, grads, or percent) for the tilt and bearing
1971 * aven: All length units are now translatable.
1973 * aven: Split log_fl_error helper function out of CHECK_GL_ERROR macro, which
1974 will reduce code size and also the number of deprecation warnings about
1975 gluErrorString on Mac OS X 10.9.
1977 * (Microsoft Windows version): aven: Try to work around redraw issues related
1978 to the measuring line by redrawing the whole window, which doesn't seem to be
1981 * cavern: If *units is used to try to set units for LEVEL, PLUMB, or POSITION,
1982 give an error rather than quietly ignoring the attempt.
1984 * cad3d: Make cad3d remap control characters and spaces in station names when
1985 generating PLT output in the same way aven does.
1987 * Various translation updates (particular thanks to Eric Madelaine and Dennis
1988 Baudys), including the start of a Bulgarian translation, with messages taken
1989 from Therion and elsewhere.
1991 * (Microsoft Windows version): On Microsoft Windows 2000 and newer, use
1992 GetUserDefaultUILanguage() to get the UI language to use. For older
1993 versions, continue to use GetUserDefaultLCID().
1995 * (Microsoft Windows version): The Indonesian translation will now be used
1996 automatically when the system language is set to Indonesian.
1998 * (Mac OS X version): Fix to build with wx 3.0.0 on OS X 10.9. Thanks to David
1999 A. Riggs for his work on this.
2001 * (Mac OS X version): Update buildmacosx.sh script to use wx 3.0.0, and add a
2002 checksum check for the downloaded wx sources.
2004 * Fix a lot of the compiler warnings when building with clang.
2006 * doc/manual.sgml: Add missing quantities to the list documented as accepted by
2007 *units: LEFT, RIGHT, UP/CEILING, DOWN/FLOOR (missing entirely);
2008 BACKCOMPASS/BACKBEARING, BACKCLINO/BACKGRADIENT (missing from the main list,
2009 mentioned in list of the units that can be set for them); COUNT (missing
2010 alternative name for COUNTER); DX/EASTING, DY/NORTHING, DZ/ALTITUDE
2011 (incorrectly listed as X, Y, Z). Reported by Jonny Prouty.
2013 * Test suite: Improve test coverage for cavern.
2015 Changes in 1.2.10 (2014-01-15):
2017 * aven: Fix assertion if two mouse buttons are held down at the same time.
2018 If dragging with more than one mouse button held down, releasing one causes
2019 another which is still held down to take effect. Reported by Brian
2022 * aven: If we fail to start the external editor when the user clicks on an
2023 error or warning from cavern, show an error box.
2025 * aven: If the survey has a title, add it as a top-level <title> element to
2028 * aven: Escape '<', '>', and '&' in labels in exported SVG files.
2030 * aven: In GPX export, set the <time> element to the datestamp from the 3d
2033 * aven: Don't try to write the title if it isn't set or is empty when exporting
2036 * aven: Don't bother looking up the printer page setup info when exporting.
2038 * (Microsoft Windows version): aven: Fix crash on "File->Print" or
2039 "File->Export" under Windows XP, reported by Brian Clipstone.
2041 * (Microsoft Windows version): aven: Fix error dialog about an incorrectly
2042 encoded filename which could occur if run without being asked to load a file
2045 * (Microsoft Windows version): aven: Compile with optimisation on.
2047 * img library, aven: Although processed CMAP data files are often referred to
2048 as "CMAP .XYZ files", it seems that actually, the extension .XYZ isn't used,
2049 rather .SHT (shot variant, produced by CMAP v16 and later), .UNA (unadjusted)
2050 and .ADJ (adjusted) extensions are. Since we've long checked for .XYZ, we
2051 continue to do so in case anyone is relying on it, but also check for the
2054 * img library: Add new "datestamp_numeric" field to struct img giving the
2055 datestamp as a time_t in UTC (or (time_t)-1 if there's no datestamp or we
2056 failed to convert it). For .3d >= v8, this field is reliable. We attempt to
2057 convert date strings in .3d <= v7 and CMAP XYZ files, but may get the
2060 * img library: Fix my_strcasecmp() to handle top-bit set characters better.
2062 * cavern: Fix NULL pointer dereference when processing Compass DAT file without
2065 * doc/manual.sgml: Update references to Survex 1.1 which should be to 1.2.
2067 * doc/manual.sgml: Note the station length limit Smaps used.
2069 * Fix some compiler warnings if built with glibc's fortify source feature
2072 Changes in 1.2.9 (2014-01-08):
2074 * Document --3d-version in cavern man page and the manual.
2076 * aven: Fix compilation error in movie export code with recent libavi.
2078 * aven: Fix warning on stderr when export a movie as MPEG.
2080 * img library: In non-hosted mode, don't define GETC and PUTC if they're
2081 already defined, to allow easy overriding with getc_unlocked() and
2082 putc_unlocked() (which are significantly faster on Linux).
2084 * img library: In non-hosted mode, check that int is at least 32 bits,
2085 and if not, use long. In practice, platforms with 16 bit int are mostly
2086 obsolete, but it's not hard to be portable here.
2088 * img library: Add test that img.c and img.h compile in non-hosted mode
2089 (regression test for issue fixed in 1.2.8).
2091 * (Microsoft Windows version): aven is now built with wxWidgets 3.0.0.
2093 * Update translations from launchpad and from existing similar messages.
2095 * Fix some compiler warnings.
2097 Changes in 1.2.8 (2013-10-29):
2099 * cavern: Fix handling of anonymous wall stations ('..' by default) to
2100 implicitly set the SPLAY leg flag, as was intended. Reported by Thomas
2103 * cavern: Tweak .err file output not to lose the space in front of certain
2104 statistics when the value gets large.
2106 * cavern: Eliminate redundant progress message when solving simultaneous
2109 * aven: Add a format drop down to the export dialog, and only show fields which
2110 are meaningful and supported for the currently selected export format. The
2111 format defaults to that used most recently. The "Elements" and "View" boxes
2112 have been swapped in the print and export dialogs as that layout works much
2113 better when the "View" box is hidden.
2115 * aven: Changing checkboxes in the print or export dialog didn't work in 1.2.7
2116 - now works again. Reported by Anthony Day.
2118 * aven: Add GPX export (based on findentrances patch from Olaf Kähler). In
2119 this release the projection which the survey coordinates are in defaults
2120 to the BMN M31 grid used in the Totes Gebirge in Austria. On Unix, you
2121 can edit ~/.aven and add a new line setting 'input_projection' to a PROJ
2122 projection string. The ability to specify this projection in a better
2125 * aven: New export options "Origin in centre" and "Full coordinates" - the
2126 latter fixes #10. GPX and PLT output implicitly force "full coordinates".
2128 * aven: The "Sketch" vector drawing program got renamed to "Skencil" some
2129 time ago, so update references.
2131 * aven: Make the Presentation->Play menu item a checkbox, to avoid a warning
2132 with wxMSW 2.9.5. Reported by Brian Clipstone.
2134 * aven: Make right click in an empty presentation mark the current position and
2135 open it to edit, instead of crashing.
2137 * aven: Update movie export code to work with latest libav API. Reported by
2140 * aven: Improve reporting of errors during the process of exporting a movie.
2142 * aven: Don't try to close the movie if we aren't producing one.
2144 * aven: Fix assertion failure when double-clicking on the survey with wx2.9.
2146 * aven: Fix to build with wxMSW 2.9.5.
2148 * aven: Fix to build with wx 2.9.5 with wx2.8 compatibility disabled.
2150 * cad3d: The "Sketch" vector drawing program got renamed to "Skencil" some time
2151 ago, so add a new --skencil option to specify this output format. The old
2152 name (--sketch) is still recognised for compatibility.
2154 * cad3d: Make --marker-size work for Skencil and SVG output.
2156 * dump3d: Make --show-dates option show dates for XSECT.
2160 + Fix to work once more when used outside of Survex (missing definition of
2161 max() macro and a bad call to free() in img_close() for a file opened for
2164 + Use lround() instead of round(), and make the tests around whether we use
2165 the library function or the our fallback implementation saner.
2167 + Fix // comments in C code for portability to pre-C99 compilers which don't
2168 support these as an extension.
2170 + Can now be compiled as C++ as well as as C.
2172 * (Microsoft Windows version): The installer is now built with a newer version
2173 of Innosetup, and includes translations for all the languages which Survex
2174 itself has any translations for.
2176 * (Microsoft Windows version): aven is now built with wxWidgets 2.9.5.
2178 * Minor translation updates.
2180 * tests/Makefile.am: Distribute files for "normal_bad" testcase.
2182 Changes in 1.2.7 (2013-07-27):
2184 * Add support for anonymous stations, which are indicated by one, two or three
2185 separator characters - with the default separator of '.', that means '.',
2186 '..', and '...' are anonymous stations. Single separator ('.' by default)
2187 is an anonymous non-wall point, double separator ('..' by default)
2188 is an anonymous wall point at the end of an implicit splay), and triple
2189 separator ('...' by default) is an anonymous point (with nothing special about
2190 the leg). A new *alias command allows '-' to be mapped to '..' for
2191 compatibility with pocket topo: *alias station - ..
2193 * New version 8 of the 3d format:
2195 + Supports new flags img_SFLAG_ANON and img_SFLAG_WALL.
2197 + New explicit file-wide flag for 'this is an extended elevation', rather
2198 than modifying the survey title to indicate this.
2200 + The survey prefix is often unchanged from one leg to the next, so use a
2201 spare flag to compactly indicate when there's no label change.
2203 + The data style of each leg is now stored.
2205 + The "processed at" time is stored as seconds since 1970 rather than a
2206 human-readable string.
2208 + Since 3d v8 features significant changes to the format, the format
2209 documentation for v7 and earlier has been split off into 3dformat-old.htm.
2213 + New station flags img_SFLAG_ANON and img_SFLAG_WALL.
2215 + Handle .pos files containing unnamed stations - don't suck the next line in
2216 as the station name, and set img_SFLAG_ANON for them.
2218 + Repurpose the long unused fBinary parameter to img_open_write() as a flags
2219 parameter, and add img_FFLAG_EXTENDED to specify that this is an extended
2220 elevation, in place of appending " (extended)" to the title. Internally we
2221 still append this to the title (and remove it upon reading) when writing
2222 3d v7 or earlier, but for the new 3d v8 format, this flag is stored
2223 explicitly in the file.
2225 + img.h: Add comments for the lists of "Leg flags" and "Station flags".
2229 + We now require at least wxWidgets 2.8.0 - it was released over 6 years ago
2230 now, and the wx developers consider even 2.8 to be rather long in the
2231 tooth. We stopped testing building with wxWidgets 2.6 some time ago, and
2232 formally dropping support for older versions allows a number of workarounds
2233 to be removed from the aven source code. Also, features deprecated in
2234 wxWidgets 2.9 are no longer used in our code.
2236 + Don't run incremental search on every key-press, as on a slow machine the
2237 short initial search(es) will take a while but not be useful. Instead only
2238 actually run the search when we're told there are no more key-presses
2241 + Implement support for including cross-section information in exported SVG
2242 and DXF files (ticket#4). The DXF export is untested currently.
2244 + Show splay legs faded by default, with menu options to hide them or show
2245 them like other legs.
2247 + Speed up loading a .3d file with cross-sections by using a map to convert
2248 station names to positions.
2250 + In the cavern log window, don't highlight a file:linenumber if there's no
2251 message after it, which avoids highlighting the "Included from" lines
2254 + Fix not to crash when trying to report an error while starting up.
2256 + (MacOS X version): Change the menu shortcut for "Full Screen Mode" to be
2257 the OS X standard shortcut Shift-Command-F (previously we used F11, but
2258 that's used by the desktop).
2260 + Add checks for errors when reading the font file.
2262 + Remove useless extra quoting when invoking vim to show the location of an
2265 + Include GL/gl.h before GL/glext.h (needed on Debian wheezy).
2267 + Use wxValidator to simplify keeping svxPrintDlg member variables and fields
2268 in the dialog in sync.
2272 + Demote errors about invalid dates to warnings, since we've accepted *date
2273 for ages without any checks on the value, and so existing datasets
2274 probably contain invalid dates and dates in other formats. (ticket#19)
2276 + New *alias command allows '-' to be mapped to '..' for compatibility with
2277 pocket topo: *alias station - ..
2279 + We want to warn if there's a clino reading which it would be impossible to
2280 have read from the instrument (e.g. on a -90 to 90 degree scale you can't
2281 read "93" (it's probably a typo e.g. for "39"). However, the gradient
2282 reading from a topofil is typically in the range 0 to 180, with 90 being
2283 horizontal. Really we should allow the valid range to be explicitly
2284 specified, but for now we infer it from the zero error - if this is within
2285 45 degrees of 90 then we assume the instrument can read between 0 and 180
2288 + If the survey isn't all connected, still run survey tree checks and report
2289 errors and/or warnings which might suggest typo locations. Thanks to Kevin
2290 Dixon for the report which highlighted this issue.
2292 + Report a warning if *begin SURVEY has a separator character in SURVEY.
2294 + Report column numbers as well as line numbers for some cavern errors and
2297 + Adjust width of node stats table to fit longest count when there are more
2298 than 9999 of a particular order of node.
2300 + If the argument to *include has an opening double quote but the closing
2301 double quote is missing, then skip trying to open the file.
2303 + Move "Station X referred to just once" warning after non-existent survey
2304 check - if both fire, the non-existent survey error is likely to be more
2307 + We no longer follow an error for a bad reading in passage data with a bogus
2308 "End of line not blank" error, but instead check the remaining readings on
2311 + We no longer follow an error about OMIT for a required reading with a bogus
2312 "End of line not blank" error.
2314 + Report an error if the scale factor in *calibrate is zero - it doesn't make
2315 sense and probably means someone reversed the arguments to *calibrate.
2317 + Report the parent include files starting from the outermost, as that's more
2318 logical when there are multiple levels involved.
2320 + If we were expecting a numeric field and instead get something which starts
2321 with '+', '-', or '.' but which isn't a number, then fix the error to
2322 include that character in the token reported.
2324 + Simplify handling of quantity lists to only recognise 'DEFAULT' as the
2327 * cad3d: Check for errors from img_rewind() and report them.
2331 + Build, install and package dump3d as standard - it's useful for grabbing
2332 info from 3d files in scripts.
2334 + Add --show-dates option.
2336 + Show only 2 decimal places on coordinates and passage dimensions.
2338 + Report the data style of legs.
2340 + Report if the file is an extended elevation.
2342 + Report img_STOP as STOP rather than CODE_0xffffffff.
2346 + cavern.tst: Fix equatenosuchstn testcase (added in 1.2.6) to normalise the
2347 expected output so it passes reliably.
2349 + cavern.tst: Run diffpos <expected> <actual> so the reports of 'Added' and
2350 'Deleted' stations upon failure are the more natural way round.
2352 + Add more testcases, expand some existing testcases, and add expected output
2355 * (Microsoft Windows version): Use wx-config's --cc and --cxx flags to find the
2356 appropriate C and C++ compilers to use, and link mingw build statically to
2357 avoid needing the libgcc DLL (which newer GCC seems to have by default).
2359 * (Unix version): When determining the character set for command-line tools,
2360 check environmental variable LANG after LC_ALL and LC_CTYPE.
2362 * When determining the language, check environmental variable LC_ALL before
2363 LC_MESSAGES and LANG (but after SURVEXLANG).
2365 * If we don't find the message file, only give an error if it was specified
2366 with SURVEXLANG, since that is an explicit instruction to Survex, whereas
2367 LANG, LC_ALL and LC_MESSAGES are essentially system "preferred locale"
2370 * There are a handful of hard-coded English message strings for reporting
2371 errors trying loading message files, etc. These are all now ASCII, as if we
2372 fail trying to open a message file, it's more likely the encoding isn't
2375 * Prune strings we are no longer using and are probably unlikely to use again
2376 into a new file po_codes_dead, so that translators don't get presented with
2379 * Merge lots of translation updates. Most translations are now complete or
2382 * Add start of Indonesian translation from Arief Setiadi Wibowo.
2384 * Fix various compiler warnings when building from source.
2386 * Include scripts gdtconvert and gen_img2aven in the source distribution.
2388 Changes in 1.2.6 (2012-02-23):
2390 * (Mac OS X version): Fix so that cavern finds its messages when run by aven.
2392 * (Microsoft Windows version): Include JPEG images for aven in the installer
2393 package (ticket#35).
2395 * cavern: If we have a reference to a station in a non-existent survey, give a
2396 helpful error rather than saying the station hasn't been exported from the
2397 survey. (Bug reported by Martin Green via email)
2399 * aven: Fix to build with a non-Unicode wxWidgets library. Patch from Olaf
2402 * findentrances: Add findentrances utility from Olaf Kahler which produces a
2403 .gpx file with waypoints for entrances. This needs libproj so is disabled
2404 by default for this release - to enable it install the development stuff for
2405 libproj and build survex with:
2407 make FINDENTRANCES=findentrances
2408 make install FINDENTRANCES=findentrances
2410 * dump3d: Add support for showing img_ERROR_INFO items.
2412 * doc/3dformat.htm: Merge in some improvements from Mike McCombe.
2414 * Incorporate a French translation from launchpad I'd previously copied the
2415 English version of by mistake. Attempt to correct mistranslation of "survey
2418 Changes in 1.2.5 (2012-01-03):
2422 + The survey tree in the left panel is now in sorted order once more.
2424 + No longer fails with an assertion if used for a long time (we were leaking
2425 an OpenGL list each time one had to be regenerated).
2427 + Now builds with newer FFmpeg library.
2429 + Draw measuring line in front of the indicators rather than behind them.
2431 + Loading a new file (or reloading the current one) no longer invalidates
2432 the OpenGL lists for the compass and clino, so will be a fraction faster.
2434 * Improve handling of attempts to look up translated messages before the
2435 message subsystem is fully initialised (which only happens if there's an
2438 * Improve the survex(7) man page text, and fix it to be marked as section 7 in
2439 the man page source as well as in the filename.
2441 Changes in 1.2.4 (2012-01-01):
2445 + A change in 1.2.3 meant that aven tried to use OpenGL before it was
2446 initialised, which doesn't cause problems in some machines, but causes aven
2447 to abort on others. This is now fixed, and there's a check in place to
2448 help avoid similar issues in future. (ticket#34)
2450 + Always use metres or feet for the depth colour key, and chose a consistent
2451 precision by looking at the depth range. (ticket#30)
2453 + Show the depth units below the colour bar rather than after every value.
2455 + When zooming way in, stay in metres rather than switching to cm.
2457 + On the scale bar, say “1 mile” rather than “1 miles”.
2459 * Translation updates for Catalan, French and Slovak.
2461 Changes in 1.2.3 (2011-12-31):
2463 * Fix to build with wxWidgets 2.9.2.
2465 * (Mac OS X version):
2467 + Processing .svx files from aven now works.
2469 + Remove spurious blank lines from the licence text in "Get Info".
2471 + Don't create the help menu at all, as it is empty (because the "About"
2472 entry goes elsewhere) and sometimes seems to appear in the UI.
2474 + INSTALL.OSX: Update to reflect current status.
2478 + Fix Y coordinates of surface surveys on printouts. (Closes #32)
2480 + Improvements to text plotted on the survey pane:
2482 - Support plotting Unicode character points > 256 by lazily loading the
2483 data for them from the font file and plotting them with a direct call to
2484 glBitmap(), which is slower but doesn't require a display list per
2487 - Adjust the spacing from fixed width to putting a one pixel gap either
2488 side of each one character (so two between adjacent glyphs). Mostly this
2489 reduces the horizontal width, but it adds a pixel for characters like "m"
2490 and two in a few cases.
2492 - Fix .pixelfont file generation to correctly handle characters wider than
2495 + Fix expected cross shape so don't always reject using texture mapping to
2498 + As we read a survey file, eliminate tubes consisting of zero XSECTs as well
2499 as those consisting of just one. Previously we would trip over the empty
2500 tube later. Such tubes can for example be created by extend if a splay shot
2501 is the start or end of a tube.
2503 + Make the green colour used for entrances in the survey tree the same
2504 (slightly darker than before) green used for the entrance blobs.
2506 + Report the version of the library we're actually running with if built
2507 against wx >= 2.9.2. Make it clear that the version reported is the
2508 version *built* with for wx < 2.9.2.
2512 + Copy the end markers for passage tubes.
2514 + Preserve left and right data for tubes (previously they were set to -1.0
2515 which means "no info").
2517 * img library: Fix incorrect comment in img.h which claimed that img_XFLAG_END
2518 was no longer used - it certainly is!
2520 * Use curly double quotes instead of "`" and "'" to quote filenames, etc in
2521 messages, and curly single right quote instead of straight ASCII apostrophe.
2522 Fall back to using straight ASCII versions if we can't represent them in the
2523 current character set.
2525 * Translation updates for Catalan, French, Slovak and Spanish.
2529 + Add test coverage for interleaved diving data.
2531 + Add testcase for diving data with topofil-style distance.
2533 Changes in 1.2.2 (2011-10-06):
2537 + Replace the textured-mapped font drawing with an approach based on
2538 glBitmap. This doesn't suffer from the character alignment issues which
2539 the textured-mapped fonts had, and is actually significantly faster on some
2540 machines. The current font used is (mostly) fixed-width, but this isn't an
2541 inherent limitation - it was just the easiest font data to convert to a
2544 + Fix assertion failure due to rounding differences on loading certain .3d
2547 + Fix assertion failure when turning on 3D passages if they stick out higher
2548 or lower than any station. (ticket#29)
2550 + Fix grid not to disappear when blobs are turned on and blobs are drawn
2553 + If a degree sign isn't available in the character set in use, transliterate
2554 it to 'dg' rather than skipping it.
2556 + Fix message which should have been a degree sign but got lost in the format
2557 change for 1.2.0 and then got reassigned in 1.2.1. Externally, this means
2558 that bearings in the status bar now have a degree sign after them if they
2559 are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
2561 + Fix print dialog to calculate the scale required for "One page" right
2562 before it calculates how many pages are required, so we don't end up
2563 something other than 1x1 being shown when the user changes settings.
2565 + Update the calculations for picking a scale and for deciding how many
2566 pages are needed to take into account the change in info box height made
2569 Changes in 1.2.1 (2011-10-04):
2571 * Translation updates for US English.
2575 + Rename the "depth bar" to "colour key" in documentation, menus, etc since
2576 it now shows colours for dates and errors as well as depths.
2578 + In the colour key for "colour by date", change "No info" to "Undated".
2580 + Remove the dark grey background from the colour key and just put a single
2581 pixel black border around the colours. This is more in keeping with the
2582 other controls, and means the colours are now on a black background so more
2583 visually similar to the survey legs.
2585 + Move the colour key's "Undated"/"Not in loop" entry down a little to
2586 improve the appearance. Make each section a pixel taller.
2588 + Allow "Colour by X" to be selected even if there's no data for X or only a
2589 single value of X used (the colour key is much smaller in these cases, and
2590 does still provide some useful information).
2592 + Fix incorrect calculation of depth colouring for survey legs which straddle
2593 a depth band boundary.
2595 + The scale bar, compass, clino, and colour key now all have right click
2596 menus which allow related actions to be performed (especially handy in
2599 + Improve the font used on the survey pane - it now contains the '-'
2600 character (so the clino now shows negative angles as negative, and dates
2601 in the colour key are now hyphenated). Also the spacing and alignment
2602 are a little better, though still not perfect.
2604 + PLT file export now handles spaces and control characters in station names
2605 by escaping them with '%' as in URLs.
2607 + Pressing "Enter" on a station in the tree control now centres the view on
2610 + The scale bar is now cached in an OpenGL display list since it often gets
2611 redrawn exactly the same - for example, when rotating, panning, etc.
2613 + Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
2614 then forces a refresh of the survey pane. This is intended as a debugging
2615 aid - if pressing F5 changes the display at all then there's a missing case
2616 where a list should have been invalidated (please report if you find such
2617 a case as it is a bug).
2619 + We now automatically track which OpenGL display lists need to be
2620 invalidated on window width or height changes.
2622 + Increase scale bar maximum width from 65% of the window width to 75% as it
2623 was in 1.0.x (except that if that would overlap the clino we now reduce
2624 that proportion down until it reaches 50%). Make the limit of zooming in
2625 the same as in 1.0.x. (ticket#23)
2627 + (Linux version): Previously wxGTK didn't really handle showing a dialog if
2628 the application was fullscreen (the dialog got opened under the main
2629 window!) To work around this, aven would switch out of full screen mode
2630 temporarily while showing a dialog. This case works properly with recent
2631 wxGTK, so disable our workaround with versions we know work. Also, apply
2632 the workaround only for wxGTK, not everywhere except on Microsoft Windows
2633 as there's no reason to think we need it for other platforms.
2635 + Grey out the "View North" action when we're already viewing North, and
2636 similarly for other compass points.
2638 + (Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
2639 info in the "About" dialog.
2641 + Fix to set the correct filename on the root of the survey tree - previously
2642 the filename of the previous file loaded was used!
2644 + The movie export code now works with newer versions of the FFmpeg libraries
2645 as well as still working with older versions.
2647 + Fix mixed up messages - the print dialog now says "View" on the left
2648 subgroup of controls rather than some unrelated message.
2650 + On printouts, combine the "Plan View"/"Elevation" info box field with the
2651 field which gives the bearing and reduce the height on the info box by the
2652 removed field, so it's now 3cm for plans and elevations, as for extended
2653 elevations. Report the tilt angle for tilted elevations which it seems has
2654 been missing for ages (it's not in recent 1.0.x either).
2656 + Tweak the exact positioning of informational text on printouts to look
2657 nicer and make better use of the available space.
2659 + Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
2662 + Make the sign of the tilt angle for printouts consistent with the sign
2663 shown by the "clino" in the survey pane.
2665 + In the "Print" dialog, when in plan view disable the "Plan view" button,
2666 and similarly for the "Elevation" button.
2668 + (Microsoft Windows version): Sort out appearance of custom cursors.
2670 + If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
2672 + (Mac OS X version): F11 puts aven into full screen mode, but apparently
2673 you can't get out again easily, so add code to explicitly check for F11
2674 being pressed and toggle full screen.
2676 * (Linux version): Fix the RPM .spec file for where man pages now get installed
2677 and package aven.svg and the vim support files. (Fixes from James Begley)
2679 * "make check" now performs several checks on the translation files.
2681 * More messages are now available to be translated.
2683 * cavern: Fix reporting of ranges of survey coordinates, which was broken by
2684 the message handling changes in 1.2.0.
2686 * Fix warning when compiling with GCC.
2688 * INSTALL: Mention building wxWidgets with --enable-unicode. Mention using
2689 sudo for installing on Unix.
2691 * In the manual, replace the instructions for building from source with a
2692 pointer to the clearer instructions in INSTALL.
2694 * In the manual, make it clear that installing with administrator rights
2695 also applies to newer platforms than XP.
2697 * doc/TODO.htm: Update.
2699 Changes in 1.2.0 (2011-09-20):
2701 * Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
2704 * tests/smoke.tst: aven no longer requires an X display for --help or
2705 --version, so replace skip of this check with a check that this remains the
2708 * We now use the standard .po and .pot file formats for storing translations
2709 (rather than the Survex-specific messages.txt format), and then translate
2710 these into Survex's .msg format.
2712 * (Unix version): Move survex man page to section 7 (since it isn't documenting
2715 * (Unix version): Write each generated man page to a temporary file, then
2716 atomically rename, to avoid leaving an empty or partial man page behind if
2717 docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
2718 recurrence of that).
2720 * (Unix version): Default to installing docs into /usr/share/doc/survex rather
2721 than /usr/doc/survex.
2725 + Fix handling of accented characters in the survey pane.
2727 + Aven icon redrawn in SVG format - it's now a vector image which looks
2728 nicer at larger sizes.
2730 + Explicitly request double-buffering, which seems to be needed for systems
2733 + Fix crash while trying to load certain .3d files.
2735 + Movie export code updated to work with more recent versions of FFmpeg.
2736 Currently this is disabled in Microsoft Windows builds, pending getting the
2737 required libraries set up for building releases.
2739 + Reporting of errors during movie export improved.
2741 + Force playback speed to "x1" during movie export.
2743 + Use stock IDs for buttons where appropriate - such buttons may now be
2744 rendered with icons on some platforms.
2746 + If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
2749 + (Unix version): Remove special handling for toggling "full screen" on wxGTK
2750 as it's no longer required with modern versions.
2752 + Don't redraw the survey on every mouse movement in the survey pane unless
2753 the measuring line is (or just was) active. (ticket #17)
2757 + Drop "non-fatal" from the report of how many errors there were at the end
2758 of the run - it just confuses users - we won't even get here if there's a
2761 + Add --3d-version option to allow the user to specify the version of the 3d
2762 format to output. (ticket#21)
2766 + Make the highest and lowest valid values for img_output_version available
2767 in img.h as IMG_VERSION_MIN and IMG_VERSION_MAX.
2769 * (Mac OS X version): Fix buildmacosx.sh script to check where the temporary
2770 volume actually gets mounted. Fix URL for downloading wxWidgets.
2772 Changes in 1.1.16 (2011-05-16):
2774 * Translation updates for German, Spanish, Italian, Portuguese, Brazilian
2775 Portuguese, and US English.
2777 * Use horizontal ellipses character rather than '...' and right arrow character
2778 rather than '->' where these characters are available.
2780 * (Unix version): Link with -lGL, if it exists, to support linking with gold or
2781 GNU ld --as-needed (Debian bug #615781).
2785 + Fix code typo for IMG_API_VERSION == 0 case.
2787 + Fix code typo in code used when IMG_HOSTED isn't defined.
2789 * doc/TODO.htm: Remove entries which have now been done.
2791 * (Microsoft Windows version): aven: We now include all the available
2792 translations for messages from wxWidgets, which means that standard widgets
2793 will appear translated where available even if Survex messages aren't
2796 Changes in 1.1.15 (2010-10-15):
2800 + In the cavern log window, change the "Rerun" button to "Reprocess" to
2801 follow terminology in manual and elsewhere. Fixes ticket#15.
2803 + When displaying output from cavern, don't update the window after every
2804 line, but only when we don't have data from cavern pending. Hopefully
2805 addresses ticket#12.
2807 + If we aren't using GL_POINTS for blobs, draw them using a series of
2808 abutting lines rather than with gluDisk which is faster and gives a
2811 + Check whether blobs and crosses actually render correctly as points/point
2812 sprites, and if they don't, fall back to drawing them with lines. The
2813 best method is cached on disk, and rechecked automatically if the graphics
2814 hardware is changed or the drivers upgraded.
2816 + Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
2817 though, so we still enable USE_FNT by default).
2819 + Don't offer "All files" wildcard in presentation save dialog.
2821 + (Microsoft Windows): Handle filenames with non-Latin1 characters in in
2824 + (Microsoft Windows): Quote filenames with spaces and metacharacters in
2825 when running cavern from aven. Fixes ticket#11.
2827 * editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
2829 * diffpos: Handle files with duplicate labels in better - extend generates
2830 duplicate labels when it breaks a loop.
2832 * Enable eswap-break testcase now that diffpos handles duplicate station names.
2834 * New v7 of .3d format which stores survey dates as number of days since
2835 January 1st 1900, so we now support dates from 1900-2078 (rather than
2836 1970-2037) with a smaller file size. The img API is now versioned - you
2837 can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
2838 gives the survey dates in days in days1 and days2 instead of as time_t
2839 values in date1 and date2. Fixes ticket#14.
2841 * Consistently use http://survex.com/ rather than http://www.survex.com/ - the
2842 former has been the canonical name for some time, with www.survex.com just
2845 * (Unix version): Use unlocked file I/O if available, which can be much faster
2846 in some cases (we don't need the locking as we don't do multithreaded file
2849 * (Mac version): Fix compilation failure due to clash with Point in Mac OS X
2852 * (Mac version): buildmacosx.sh now works again.
2854 * Most tests weren't actually running any testcases (looks like a sh
2855 portability issue). This is now fixed, and fortunately all tests still pass.
2857 * Include the extra .isl translation files for Innosetup in the source archive.
2859 Changes in 1.1.14 (2010-07-26):
2861 * Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
2865 + After processing survey data, if there were warnings or errors, add a
2866 "Rerun" button to allow easy reprocessing after fixing problems. If there
2867 were only warnings, also add an "OK" button to allow moving on to viewing
2868 the processed survey data (fixes ticket#13).
2870 + Optimise updating of the cavern log window (hopefully fixes ticket#12).
2872 + Fix links in cavern log window to link from exactly '<file>:<line>' (and
2873 not the ': ' after), and to make the title for the terminal the
2874 warning/error message. Avoid false positives by checking that '<line>' is
2877 + Don't double escape the contents of href and target in links in the cavern
2880 + Improve handling of the splitter window, fixing behavioural glitches in
2883 + Highlight stations matching any current search when a file is loaded.
2886 + (Mac version): Fix build issue due to Mac OS X polluting the global
2887 namespace with its own "Point" class.
2889 + (Unix version): The Gnome print dialog has its own preview window so
2890 suppress ours if using the Gnome one.
2892 + (Unix version): Link aven with -lGLU which SuSE Linux needs.
2894 + (Microsoft Windows version): Fix handling of a double-click on the survey
2895 tree when built with wxWidgets >= 2.8.11.
2897 * cavern: Report relevant file and line number for three warnings which didn't
2900 * (Unix and Mac versions): configure: Update the wx-config probing code -
2901 wxmac-config etc aren't present with newer wxWidgets versions so there's no
2902 point looking for them now.
2904 * (Mac version): buildmacosx.sh: This script builds a diskimage with Survex in
2905 for easy installation. Update it to work with the latest Survex versions
2906 (use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
2907 private wxWidgets, use 2.8.11 not 2.7.0-1).
2911 + Correctly capitalise "GTK".
2913 + Note that on Linux we only regularly test builds with the GTK+ version
2914 (change taken from 1.0).
2916 * Fixed the cad3d man page, which was an empty file in 1.1.13.
2918 Changes in 1.1.13 (2010-06-16):
2920 * Say "wxWidgets" instead of "wxWindows" consistently.
2922 * img.c: Fix small memory leak (filename_opened member).
2924 * cad3d, aven: Fix export to SVG when a label contains a '%' character.
2928 + wxWidgets 2.6.0 or newer is now required.
2930 + A "Unicode" build of wxWidgets is now supported. An "ANSI" build may still
2931 work but hasn't been tested recently (all packaged versions of wxWidgets
2932 seem to be Unicode now).
2934 + Fix potential uses of uninitialised variables which may have been causing
2935 occasional glitches when loading a file on start-up.
2937 + Improvements to the handling of the font used for plotting labels and other
2938 text on the survey pane:
2940 - Loading the font file is more efficient.
2942 - Character spacing is improved.
2944 - Default font is now anti-aliased.
2948 - Add "Copy" button to copy the system info to the clipboard for easier
2951 - List OpenGL extensions last, since there are usually lots of them with a
2954 - Fix 100% CPU usage while the "About" dialog is open.
2956 + Processing .svx files:
2958 - Passing a .svx file on the command line now works better.
2960 - Put the survey data log window in a splitter in the usual frame rather
2961 than opening a separate frame for it.
2963 - Auto-scroll the log window until we've reported a warning or error.
2965 - Fix small memory leak.
2967 + The presentation filename now defaults to using the basename of the
2968 currently loaded dataset, but we always prompt before we first save with
2971 + Reduce memory usage when saving a screenshot.
2973 + Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
2974 persist the window size (and maximised or fullscreen state) between
2977 + Fix reporting of OpenGL errors.
2979 + Fix glitches when tilting while looking East.
2981 + Added Portuguese and Slovak translations of wxWidgets messages.
2985 + Rationalise manual formats - replace PostScript with PDF and drop RTF.
2987 + Drop the "alternative manual formats" self-extracting zip file - people
2988 will generally just want one of the formats, so downloading several
2989 together isn't very useful.
2991 + 3dformat.htm: Update for v6 format (thanks to Mike McCombe).
2993 + GPL.htm: Replace HTML version of licence with a link to the version on
2996 + ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
2997 low level to be of interest to non-developers, and developers can look at
3000 * (Unix version): configure: New preferred name for specifying wx-config script
3001 is WX_CONFIG. WXCONFIG still supported for compatibility.
3003 * (Linux version): Source RPM package dropped as you can just build an RPM
3004 package from the source tarball.
3006 * (Microsoft Windows version): The installer is now created with a newer
3007 version of InnoSetup, which gives a 10% smaller download.
3009 Changes in 1.1.12 (2007-02-07):
3013 + Remember the window size or maximised/fullscreen state between invocations.
3015 + Add options dialog to "Export" similar to the one for "Print".
3017 + The "number of pages required" in the print dialog now updates when you
3018 change what is to be shown (underground legs/surface legs/station
3021 Changes in 1.1.11 (2006-11-25):
3023 * Updated Czech, Spanish, and Slovak translations.
3025 * (MacOS X version): Assorted OS X specific tweaks and fixes.
3029 + Pick a smaller and clearer font for labels.
3031 + Fix character spacing.
3033 + Tweak display of bearing and elevation angles to look nicer with
3036 + Use the title from the 3d (or plt, etc) file for the window title
3037 rather than the filename.
3039 + Show distances to 2 decimal places rather than the nearest integer.
3041 + Only consider underground legs when calculating the depth bands and
3044 + Add "Colour by Error".
3046 + Add entry for "white" in date and error keys.
3048 + When setting the view to a single point, don't change the scale.
3050 + If reloading the same file, don't change the view
3052 + Fix filetypes selector in open dialog.
3054 + Fix the charset we use for aven in certain cases.
3056 + Call msg_init before using msg_lang or it won't ever be set!
3058 + Pass wx the full language code to initialise the C library locale.
3060 + Fix bug in generating prefix tree view which could lead to a bogus
3061 leading dot on some survey names (bug probably introduced in 1.1.10).
3063 + "New Presentation" now ensures that the side panel is open
3065 + Fix updating of cached opengl lists when the view is reset to the
3068 * Ignore LANG if it starts with a digit to avoid problems with bogus value for
3069 LANG which AutoCAD installation seems to set on MS Windows.
3071 * (Unix version): configure: Allow SGMLTOOLS and DOCBOOK_TO_MAN to be
3072 specified. Either/both can be set to ":".
3074 * dump3d: Report unknown (to dump3d) codes returned by img.
3076 * img library: Flag all stations as underground in the old "ASCII" .3d format.
3078 Changes in 1.1.10 (2006-07-14):
3080 * aven: Clicking on a survey name in the survey tree now highlights it in
3081 the map view. Double-clicking zooms the view to show the clicked survey
3082 highlighted. Clicking the root clears the highlighting and double-clicking
3083 the root restores the default view. To expand/collapse a branch, click
3084 on the "[+]" or "[-]" icon to the left of the survey name.
3086 * aven: The measuring line can now measure to anywhere in plan or elevation
3087 view (not just to a station!) In plan view the horizontal distance and
3088 bearing are shown, while in elevation view the vertical distance is shown.
3090 * aven: Moving the mouse over a station in the survey view now highlights
3091 that station in the survey tree (though it may not be visible if the
3092 survey(s) it is in aren't expanded).
3094 * aven: Clicking on a station to centre the view now moves the mouse pointer
3095 to the new location of the station (except on Mac OS X where this isn't
3098 * aven: Fix which presentation toolbar buttons are shown as depressed.
3100 * Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
3102 * vim files are now installed with the correct paths (bug introduced in 1.1.9).
3104 Changes in 1.1.9 (2006-07-04):
3106 * (Unix version): Install desktop files for aven and svxedit contributed to the
3107 Ubuntu package by Phil Bull, and corresponding pixmaps.
3109 * Fix img to filter out cross-sections which don't match the subsurvey (if
3110 specified). The API now returns img_XSECT_END to mark the end of a
3111 passage rather than setting a flag on the last img_XSECT of the passage.
3113 * Enhance integration with the vim editor - this can now colour .err files, run
3114 cavern from vim and parse error output, and run aven from vim. Tweak the
3115 existing vim mode for .svx files to fix a few minor bugs and add support for
3116 the new "*data passage" style.
3118 * aven: fix drawing of the "blob" end of the measuring line on graphics cards
3119 which can't draw large enough blobs for us.
3121 * aven: sort out confusion about what encoding everything is in which means
3122 that the distance measured by the measuring line actually gets displayed
3123 and also fixes problems with empty menu items in non-English locales in
3126 * aven: redraw grey background after a menu is closed over the aven window
3127 with no survey loaded.
3129 * aven: fix bug which caused printing to crash (introduced in 1.1.8).
3131 * aven: avoid crash on some machines when opening "About" dialog before having
3134 * aven: Translate "Plan" and "Elevation" buttons in print view dialog.
3136 * (Unix version): aven: Fix character set handling of cavern output.
3138 * cavern: Report an error if a cross-section is specified for a station which
3141 * Updated French and Italian translations.
3143 * (Unix version): aven: Fix "Can't open message file `en_US' using path
3144 `${prefix}/share/survex'" error.
3146 * Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
3147 (doesn't affect Survex itself, but other applications which use img.c should
3150 * (Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
3151 and later are caught by configure, whereas older wx versions are caught when
3154 Changes in 1.1.8 (2006.06.30):
3156 * Drop support for building with wxWidgets versions prior to 2.4.0
3157 (which was released on 2003-01-07).
3159 * aven: Printing through aven now uses settings from the "[aven]" section
3160 of print.ini, and support for hierarchical sections (using "like=")
3163 * aven: Change mouse actions to be compatible with those in Survex 1.0.
3164 The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
3165 left drag is now smart about not rotating and zooming at the same
3168 * aven: Highlighting stations now happens as you type, and pressing
3169 "Enter" or clicking the "Find" button now pans and zooms to show the
3170 highlighted stations.
3172 * aven: Left-clicking away from a station now cancels measuring line.
3174 * aven: Setting view to North, South, East, or West is now animated like
3175 the tilt from plan to elevation.
3177 * aven: Fix presentation saving to also write "." for decimal points and
3178 presentation loading to accept either "." or ",".
3180 * (Unix version): aven: Add text for all toolbar items so that aven
3181 will work with the Gnome desktop preference for displaying toolbars as
3182 icons with text or just text (wxWidgets needs fixing first though).
3184 * (Unix version): aven: Remove the ability to detach the menu bar (yell
3185 if you actually used it and I'll restore it!)
3187 * aven: Add "all survey files" option to the "open file" dialog.
3189 * (MS Windows version): aven: Fix cursor keys to pan survey.
3191 * (MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
3193 * (MS Windows version): Fix installer to work on Windows 2000 or XP if
3194 run by an unprivileged user.
3196 * (MS Windows version): Upgrade to the latest version of InnoSetup (the
3197 installer builder we use) and include new installer translations for
3198 UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
3200 * (MS Windows version): aven: Include Catalan and Brazilian Portuguese
3201 translations of messages for wxWidgets (the GUI library we use).
3203 * aven: Disable "Highlight exported points" if there aren't any.
3205 * Updates to French translation from Michel Bovey. Also updates to German,
3206 Italian, Catalan, Spanish, and Romanian translations.
3208 * (Unix version): test suite: fix smoke test to pass even without X running
3209 (it was meant to but the code had a bug).
3211 * aven: Check if OpenGL is available and exit cleanly with a helpful error
3214 * (Unix version): aven: Fix --help and --version to work without a working
3215 X display (provided it's built with wxWidgets 2.5.1 or newer).
3217 * aven: Automatically select the presentation tab of the notebook when the user
3218 selects "New Presentation" or "Open Presentation".
3220 * aven: Fix "Delete" in the presentation list to not get passed on (and so not
3221 reset to default view as well).
3223 * aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
3226 * aven: Fix Cursor Up and Down in the presentation list to move the highlight
3227 up and down instead of being passed on and moving the survey.
3229 * aven: Improve SVG output compatibility. Tested with Mozilla Firefox 1.5,
3230 Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
3231 Safari 2.0.3, and InkScape 0.42.
3233 * aven: Put a 5mm border around exported SVG files to allow for station markers
3234 and non-zero width lines.
3236 * aven: Fix crash when exporting as SVG or Sketch if labels or surface data
3239 * aven: Actually close the file we're exporting which fixes problems with it
3240 not always being fully written.
3242 Changes in 1.1.7 (2005.10.18):
3244 * cavern: Add validity checking for dates in *date commands (with feature
3245 test in testsuite). A date entered as just "year" or "year.month" now
3246 becomes a date range for the relevant period (previously it became a single
3247 date near the middle of that period).
3249 * extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
3252 * extend: Default output name for a file called input.3d is now input_extend.3d
3253 rather than just extend.3d (which was annoying if you wanted to extend
3254 several surveys in the same directory).
3256 * aven: OpenGL 2.0 always includes support for point sprites so rework
3257 our check for them to include that knowledge.
3259 * aven: Regenerate depth bar if user switches to/from metric units.
3261 * aven: Don't clear the "there" mark just because the mouse pointer has
3262 moved off a station.
3264 * aven: When processing a .svx file, put the resultant .3d file in the
3265 same directory (since that's where we then try to load it from).
3267 * aven: Fix labelling of date colouring on 32 bit platforms.
3269 * aven: If "colour by date" is on and we load a survey with no date info
3270 (or all surveyed on the same date) then set "colour by none".
3272 * aven: Make the error dialog modal and remove a signal handler once it
3273 has fired to prevent endless (or seemingly endless) cascades of error
3276 * aven: Enforce a minimum object volume diameter of 1m to avoid problems
3277 if a survey file with only one station in is loaded.
3279 * aven: Fix problems with indicators disappearing when we're drawing
3280 blobs and/or crosses the slow (but always supported) way. (Problem
3281 introduced in 1.1.6).
3283 * (Unix version): aven: Really stop setting extra toolbar margin when using
3284 GTK2.0. The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
3285 set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
3287 * (Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
3288 we've been compiled with, and which GTK+/Motif version where appropriate.
3290 * (Unix version): Fixed build on Fedora Core 3.
3292 * documentation: Updates to 3d file format specification from Mike McCombe.
3294 Changes in 1.1.6 (2005.10.10):
3296 * (MS Windows version): Distribution is about a third smaller than 1.1.5
3297 (mostly because mingwm10.dll is no longer required).
3299 * aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
3300 it, showing cavern's output in a window (with errors and warnings clickable
3301 to load the offending file into an editor), and then loading the resulting
3304 * aven: Added "Colour by Date" option.
3306 * aven: Disable "Colour by Depth" option if there's no elevation variation.
3308 * aven: Don't crash if trying to load a survey with no elevation variation.
3309 Instead turn off depth colouring.
3311 * aven: Export as HPGL added.
3313 * aven: Improved update of mouse coordinates and measuring line (thanks to
3316 * aven: Show the coordinates of either the mouse pointer or the nearest
3317 survey station to it (if there is one near enough). Showing both was
3318 confusing and meant the status bar overflowed on smaller displays.
3320 * aven: When printing an extended elevation, don't show bearing and elevation.
3322 * aven: Don't lock "flat" surveys which aren't extended elevations - a
3323 flat survey with LRUD data isn't flat any more!
3325 * aven: When we have to draw blobs and crosses the slow way (because the
3326 graphics hardware doesn't support the fast way), draw them so that they
3327 should appear at the correct depth into the 3D scene instead of on top
3330 * aven: Make "play presentation backwards" icon green to match the other
3333 * (MS Windows version): aven: Mouse clicks on the survey view now set the
3334 keyboard focus there.
3336 * (MS Windows version): aven: Fix first redraw of a newly loaded survey.
3338 * (MS Windows version): aven: Fix redrawing of measuring line.
3340 * cavern: Store dates for img_XSECT.
3342 * cavern: Fixed small one-off memory leak if you specify -o more than once.
3344 * (Unix version): Check environmental variable LC_MESSAGES when deciding what
3345 language to use for messages.
3347 * (MS Windows version): "Print" on a 3d file now prints through aven rather
3348 than the separate printer driver (Unix has done this for some time).
3350 * Removed old printer drivers.
3352 * img library: When creating a 3d file, ignore img_XSECT if we've been asked
3353 to write a file format version which doesn't support it.
3355 Changes in 1.1.5 (2005.09.20):
3357 * (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
3359 * aven: Make blobs round like they are in Survex 1.0.
3361 * aven: If the graphics drivers don't support drawing blobs using OpenGL
3362 point markers, fall back to drawing filled circles.
3364 * aven: If the graphics drivers support it, draw crosses as texture mapped
3365 OpenGL point markers which is much faster.
3367 * aven: Cross size increased to match Survex 1.0.
3369 * aven: We must update which blobs are displayed if display of surface or
3370 underground legs is toggled.
3372 * cavern: Fix handling of a *solve followed by survey data, none of which is
3373 attached to the previous data.
3375 * cavern: Fixed "No survey data" error when a *solve is followed by another
3376 *solve (or the implicit solve at the end of processing) with no data between
3379 Changes in 1.1.4 (2005.09.19):
3381 * aven: Added Aven's icon to the "About" dialog.
3383 * aven: Use localised character for the decimal point (e.g. "," in most
3384 continental European countries).
3386 * aven: Previously the survey tree would get focus and then take keypresses
3387 (e.g. "P", "L", "Delete"). Now we pass most keypresses across so they
3388 operate on the cave, and transfer the input focus across when we do.
3390 * aven: Make pressing "Return" in the tree control expand/collapse a subtree.
3392 * aven: Speed up intialisation by delaying creation of OpenGL lists until
3395 * aven: Added Mark Shinwell's bounding box with shadow of the survey.
3397 * aven: Disable the "Tubes" button/menu item when there's no LRUD data.
3399 * aven: Reworded "Restore Default Settings" as "Restore Default View".
3401 * (Unix version): aven: Set sensible default margins for printing and preserve
3402 any margin values the user specifies between runs (previously margins
3403 defaulted to 0 each time aven was run).
3405 * Documentation: Document *DATA PASSAGE in the manual.
3407 Changes in 1.1.3 (2005.09.07):
3409 * (Microsoft Windows version): Fixed build problems.
3411 * cavern: Allow OMIT character (-) for left/right/up/down.
3413 * aven: Remove an unnecessary menu separator.
3415 * aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
3417 * aven: Make the tooltip for "Hide" show the number of found stations.
3419 * aven: If * or ? is used in a glob-style pattern, force a non-substring match.
3421 * aven: Enable "New Presentation" when there's a 3d file loaded, rather than
3422 when there's a presentation loaded.
3424 * aven: Make entrances green in side panel tree list to match green blobs used
3427 * aven: Don't show surface labels if we're not showing surface data, etc.
3429 * aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
3430 make "Space" the key for this. Keep Return working "Stop Rotation" so
3431 existing users are happy, but don't advertise it.
3433 * aven: Normalise filename by adding any extension used, and use the normalised
3434 filename for file history and window title.
3436 * (Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
3437 as the toolbar buttons already have a sensible margin - the extra margin is
3438 only needed with GTK1.2.
3440 * aven: Fix handling of plumb legs in tube model.
3442 * aven: Fixed swapped L and R in tube model.
3444 * extend: Preserve UD cross-section information in extended elevation.
3446 * extend: Add new messages for John Pybus' enhancements.
3448 Changes in 1.1.2 (never formally released):
3450 * Added support for LRUD data in .svx files, in .3d files, and aven can
3451 now load and display it on screen and on printouts. The ability to "fake"
3452 LRUD data in aven is gone for now but will reappear in some form later.
3454 * cavern: Removed support for writing Chasm's 3dx format. We're going to
3455 fold any desirable missing chasm functionality into aven.
3457 * aven: Rearranged mouse actions as discussed on the mailing list. Added
3458 cursors for each different mouse action to help the user learn what each
3459 does. Also added cursors for the "compass" and "clino" as well as the
3460 scalebar to suggest to the user that they can be dragged to change the view.
3462 * (Unix version): aven: Don't segfault if LANG isn't a known language.
3464 * tests/smoketest.tst: If X windows is running, check that we can run aven
3465 with --help and --version.
3467 * tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
3468 no results are listed for it. This revealed that there was a "newline" test
3469 which should have been called "badnewline", and was a broken testcase too!
3470 Fixed all these problems.
3472 * cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
3473 and omitted forward compass/clino readings in Compass DAT files. Added
3474 a feature test for this to the testsuite.
3476 * It no longer makes sense to have an option not to build aven or to build aven
3477 without OpenGL so remove old machinery for this from configure and the
3480 * (Unix version): configure: Check if "-lXxf86vm" is needed.
3482 * configure: Better output for strcasecmp test.
3484 * aven: Fix crosses to work much better. Not a total fix - their position
3485 in the Z buffer isn't correct and they're rather slow to plot.
3487 * aven: Don't regenerate the hittest grid every time the mouse moves while
3488 animating, which solves the mysterious pausing effect (thanks go to Martin
3489 Green for spotting this!) Also clear all the status bar coordinates when
3492 * aven: Sort out clashing menu shortcuts in some languages.
3494 * aven: Fixed compilation problem on x86_64
3496 * SPUD: Pruned out stuff which has been done or which is not actually relevant
3499 * Merge various changes from 1.0 branch:
3501 + aven: Port over "printing from aven" functionality.
3503 + aven: Port over "export as" functionality,
3505 + Add David Loeffler's vim mode for .svx files.
3507 * aven: Fix check for whether a label is behind us in perspective view.
3509 * aven: Don't use an opengl list for drawing the indicators - we typically make
3510 a new list each time we plot them anyway.
3512 * Remove lingering traces of support for RISC OS and pre-386 MSDOS
3514 * aven: Set icon on non-Windows platforms too. This means that with
3515 WindowMaker on Unix you get an icon on the AppIcon by default.
3517 * configure: Update wxWindows checks to handle newer wx versions.
3519 * Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
3520 problems. They also all require Perl 5.8 now (hopefully this isn't an issue
3521 for anyone building from CVS).
3523 * acinclude.m4: Quote macro name for fix autotools warning.
3525 * Documentation: "tilt up" is "'" not ",".
3527 * aven: Add support for mousewheels (to tilt the cave).
3529 * aven: Fixed twisted transitions to and from pitches in certain cases.
3531 * aven: Pick a sensible initial window size when the user's desktop is spread
3532 over more than one monitor (works best with wx2.5 or newer, but try to do
3533 better with wx2.4 or earlier as well).
3535 * aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
3536 contents being visible before any survey is loaded.
3538 * aven: Allow a coloured texture to be used
3540 * aven: Don't initialise until we have data (to the user, this means the window
3541 is default colour (grey for most systems) not black until a survey is
3544 * aven: Fixed weird "shadowed" icons.
3546 Changes in 1.1.1 (2004-10-06):
3548 * (Microsoft Windows version): aven: Hopefully fix loading a survey file at
3551 * aven: Delay loading the bitmap for the "About" dialog until it is first
3552 needed. We want start up to be as quick as possible.
3554 Changes between 1.0.32 and 1.1.0 (never formally released):
3556 * NOTE: Survex 1.1.X releases are development snapshots made available for
3557 the purposes of allowing wider testing and getting more user feedback. Once
3558 the code has stabilised the version number will be raised to 1.2.0.
3560 * aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
3561 you're using Windows 95 - these can be obtained from:
3562 http://download.microsoft.com/download/win95upg/info/1/W95/EN-US/Opengl95.exe
3564 * aven: Solid passages - passage dimensions are currently inferred from
3565 the leg length (pretty effective as you can measure longer legs in
3566 larger passages). Use of real LRUD data coming soon...
3568 * aven: Depth colouring is now continuously varying.
3570 * aven: Colour by depth can now be turned off (and there's the start of a
3571 framework for properly implementing colour by date, error, etc).
3573 * aven: Find stations moved onto the toolbar and now uses a simple wildcarded
3574 match (? matches any character, * matches any number of characters).
3576 * aven: We now use the status bar for coordinates, distances, etc to make
3577 better use of screen space.
3579 * aven: Full screen mode (F11).
3581 * aven: Perspective view.
3583 * aven: Context sensitive cursor shape - needs more work.
3585 * aven: Mouse actions changed (hopefully they're now more natural, but
3586 you may find the change disorientating - feedback wanted on this).
3588 * aven: Added "presentations" which allow you to set up fly-through paths
3589 and load/save/run them.
3591 * aven: A presentation can be exported as a movie file.
3593 * aven: Added Save screenshot facility.
3595 * aven: Depth fogging option.
3597 * aven: Added Smooth Lines option.
3599 * aven: Added Textured Walls option.
3601 * aven: If a survey has surface legs but no underground legs, default to
3602 showing the surface legs.
3604 * cavern: Dates given to *date are now stored in the 3d file.
