11 Notable changes in gEDA/gaf 1.10.1
12 ==================================
14 * Migrated to Guile 2.2.
16 * Duplicate symbols in a library are now only considered an error if
17 one of the symbols has been referenced.
19 * Fixed handling of packages and nets in multi-page subschematics.
21 * gnetlist ignores the `--report-gui' option and falls back to console
22 output if the Python GTK bindings are missing.
24 * Added power symbols based on the newer netname= convention to the
25 standard symbol library.
27 * Moved visibility columns in the attribute editor to the left side.
29 * When promoting an attribute manually in the attribute editor, the
30 new attribute is now visible by default.
32 * After pasting objects, the newly-pasted objects are selected.
34 * Page size and orientation can be changed in the print dialog.
36 * Removed the option `bus-ripper-rotation'; both symmetric and
37 non-symmetric bus rippers are now placed correctly.

46 ...and several more which never made it to the bugtracker.
49 Notable changes in gEDA/gaf 1.10.0
50 ==================================
55 * Added the library "xornstorage" and the Python package "gaf" as a
56 (currently quite minimal) way to access gEDA/gaf functionality from
57 outside of gschem. These are on the long term intended to replace
58 libgeda, making the core gEDA/gaf functionality available as a
59 library to both gschem and other applications.
61 * Added command-line tool `xorn' for low-level schematic and symbol
64 * Added experimental XML file format (currently only supported by
65 gnetlist and the `xorn' command line utility).
67 * Objects colors are limited to 21 (up to and including FREESTYLE4).
68 More recent colors added for GUI purposes can be set in colormaps
69 but aren't automatically added to the file format specification.
71 * The symbol directories "gnetman", "verilog", and "vhdl" are now
72 installed to the new location PREFIX/share/gEDA/extra-sym/. This
73 allows adding the default library with "component-library-search".
75 * The directory to which gEDA programs write log transcripts can be
76 changed by setting the environment variable `GEDALOG' (the default
79 * All tests now use the parallel test harness, speeding up `make
80 check' runs considerably when used with multiple jobs (-jN).
83 - lp-698501 gschem file preview function renders files twice
84 - lp-698524 gnetlist ignores duplicate inout-symbols
85 - lp-698768 No ordering requirement for attribute attach/detach
86 - lp-701637 gschem "Scheme Interaction" window
87 - lp-1266316 gschem exits on color value < 0
88 - lp-1367462 undo messes with the view even though undo panzoom is disabled
89 - lp-1492834 These docked dialogs should remember their size
90 - lp-1496899 gschem: dock window wishlist
91 - lp-1497659 gnetlist -v -g spice-sdb generates bad verbose netlist
92 - lp-1514209 gschem: multiattrib Value textview improvements
93 - lp-1532794 Build fails on missing colors.h
94 - lp-1576918 Memory and file handle leak in libgeda
95 - lp-1590757 partlist3 yields wrong netlist in some cases
96 - lp-1625474 xorn does not build on FreeBSD
97 - lp-1661961 "format not a string literal and no format arguments" warning
98 ...and a lot more which never made it to the bugtracker.
104 * Tool windows are now "dockable", i.e., they can be either used as
105 modal/non-modal dialogs or docked to the edges of the main window.
107 * The action mechanism used for menu items, tool buttons, and key
108 bindings has been redesigned, making several improvements possbile:
110 - Actions can now be used interchangeably in the main menu, toolbar,
111 context menu, and keymap. They are defined in a single place
112 ("actions.c" for C actions and "builtins.scm" for Guile actions),
113 including metadata like name, icon, and tooltip.
115 - Menu items and tool buttons representing options have a little
116 check or radio box beside them indicating their current state.
118 - Menu items and tool buttons are greyed out while they can't be
121 - Toolbar and context menu are customizable.
123 - Menu and toolbar definitions are simple Scheme variables, allowing
124 users to add actions to the menu without having to copy the menu
125 definition. Actions are represented in Scheme code as applicable
126 SMOBs, allowing them to be called like procedures while retaining
127 the action information necessary for rendering the menus/toolbar.
129 - "Repeat Last Action" (usually bound to ".") uses the same logic as
130 the middle mouse button repeat action does, i.e., only actions
131 that "make sense" qualify for repeating.
133 * The menus, toolbar, and keymap have been revamped to more closely
134 resemble the "standards" for a desktop application. Some actions
135 have been assigned more accessible or memorable keys.
137 * Added a command-line option "--control-fd=stdin|FD" which allows
138 remote-controlling gschem via a file descriptor. This is intended
139 for project managers like Igor2's "genxproj".
141 * File operations have been consolidated: opening, saving, closing a
142 file and so on should now behave identical regardless of how the
143 operation was initiated. Related improvements:
145 - When opening multiple files, the first one (instead of the last
146 one) is initially shown.
148 - The symversion= mismatch dialog is shown whenever a symversion=
149 mismatch is detected while opening a file, not just for files
150 specified on the command line.
152 - gschem now keeps track of which files are untitled, listing them
153 as "untitled page" instead of assigning them a temporary filename.
154 The Scheme procedure `page-filename' returns #f for untitled
157 - "Save all" used to produce spurious "untitled_1.sch" files. This
158 was due to three issues working together, which have been fixed:
160 - When gschem is invoked without specifying filenames on the
161 command line, an untitled page is created. This page wasn't
162 removed when opening files, staying invisibly in the background.
164 - "Save all" didn't check which files needed saving but just
165 unconditionally saved anything.
167 - "Save all" didn't behave like the interactive "Save", asking for
168 a filename for untitled pages, but just saved each page to its
169 internally stored filename.
171 - The file chooser dialog on "Open" and "Save As" is now always
172 opened in the current directory.
174 - When opening a file which is already open but has since been
175 changed on disk, the user is asked whether to reload the file.
177 - When the currently edited file has been modified on disk, a
178 notification is shown offering the user to reload the file.
180 - If the user enters a filename with an unusual extension while
181 saving, a confirmation dialog is shown.
183 - When trying to open a file or descend into a subschematic which
184 doesn't exist, gschem now offers to create a new file with that
187 * Some improvements have been made to the multi-attribute editor:
189 - Editing a single attribute invokes the multi-attribute editor.
191 - Trying to edit an inherited attribute edits the attached attribute
192 with the same name if it exists, or promotes the attribute and
193 edits its value if it doesn't exist yet.
195 - Attributes are shown in the order in which they are listed in the
196 configuration (via "attribute-name").
198 * Attaching and detaching attributes now work as expected:
200 - "Attributes / Attach Attributes" used to depend on the order in
201 which objects were selected, taking the first selected object as
202 the base object to attach attributes to, regardless of its type.
203 Now, the selected objects are searched for a base object of
204 suitable type, and only if exactly one is found, the attributes
207 - "Attributes / Detach Attributes" used to work on selected
208 components and nets, detaching all attributes from these objects.
209 It now works on the selected *attributes*, allowing the user to
210 selectively detach specific attributes while leaving the rest
213 * "Lock Component" used to lock components as well as non-component
214 objects, bringing the latter into an invalid state that would last
215 until the next "Undo" (or until the page was saved and loaded back
218 This has been fixed: "Lock Component" and "Unlock Component" now
219 only operate on components, changing the color of attached
220 attributes as they used to do with any selected text.
222 * The "Light Color Scheme" (V L) selected from the menu now has a
223 truly white background. For compatibility, selecting the "lightbg"
224 colormap in gschemrc loads the old, light-gray color scheme; the new
225 color scheme can be selected as "whitebg".
227 * The library window has been made fit to be used as a dock window:
229 - When the dialog is resized to be taller than a certain aspect
230 ratio, it switches automatically to a stacked layout where the
231 preview and attribute panes are located below the symbol selector.
233 - While in stacked layout, the bottom panes can be expanded and
234 collapsed to give more room to the symbol selector.
236 - The window is automatically refreshed on library updates.
238 * Symbol editing has been improved:
240 - The page can now be scrolled to negative coordinates, making it
241 feasible to edit symbols without moving them away from the origin,
242 then translating them back. This also allows to consciously
243 choose something that makes sense for the symbol as the location
246 - The coordinate origin is now indicated with slightly darker grid
247 lines. (This can be enabled/disabled via "View / Show Origin".)
249 - The "Symbol Translate" action has been replaced with "Place
250 Origin" which lets the user select the position of the origin
253 * Added support for back-annotation from pcb-rnd.
255 * Double-clicking a subschematic component enters the subschematic.
257 * Right-clicking in path mode works as expected.
259 * Pins are allowed to have zero length.
261 * "File / Revert" only asks for confirmation if the file has been
264 * The "repeat" function of the middle mouse button now evaluates
265 actions at the current mouse position.
267 * Mouse gestures work properly again.
269 * libstroke has been merged into gEDA/gaf. This removes the
270 dependency on libstroke and makes mouse gestures always available.
272 * Added new mouse gestures for page navigation:
273 - swiping left goes to the previous, swiping right to the next page
274 - swiping right and then down enters a subschmatic
275 - swiping left and then down enters a symbol
276 - swiping up and sideways (in any combination) goes back to the
279 * The coordinate dialog has been replaced with an option to display
280 the coordinates in the status bar.
282 * Added further menu items:
284 - "Add / Last Component" (A C)
286 - "Object / Toggle Text Overbar" (T O)
288 - "View / Show Menubar" (V M)
289 - "View / Show Toolbar" (V T)
290 - "View / Show Scrollbars" (V S)
292 - "Tools / Select Locked Objects" (T L)
294 * Fixed various issues related to undo/redo:
296 - The menu items "Edit / Undo" and "Edit / Redo" now show the name
297 of the action that will be undone/redone.
299 - The current viewport used to be restored on undo/redo regardless
300 of the "undo-panzoom" setting (which prevents pan and zoom
301 operations from being recorded in the undo history). This turned
302 out to confuse users, so if the setting is enabled, undo/redo now
303 doesn't change the viewport at all.
305 - The default mode ("undo-panzoom" disabled) now works correctly.
307 - After undoing the first action which changed a page, the page will
308 be considered "unchanged" again.
310 - Adding an attribute, changing the slot of a component, replacing
311 the contents of a picture, and selecting "Pan" from the menu used
312 not to be correctly un-doable. This has been fixed.
314 - Selecting a picture to be added doesn't cause the page to be
315 treated as changed any more.
317 - "Object / Update Symbol" can't be undone with the current undo/
318 redo system, so it isn't listed as something that can be undone
321 - Several actions (attach/detach attribute, text actions, embed/
322 unembed, lock/unlock component, show/hide specific text) changed
323 the undo history even in the case that they didn't have any
324 effect. This has been fixed.
326 - Several actions (attach/detach, embed/unembed) didn't update the
327 "changed" flag correctly; this has been fixed.
333 * Refactored gnetlist:
335 - gnetlist is now part of the Python package "gaf" and uses the new
336 libraries instead of libgeda to work with gEDA files.
338 - Netlist backends can also be written in Python.
340 - When reading broken schematics and/or symbols, gnetlist doesn't
341 silently fail or produce bad output any more. Conversely, this
342 means gnetlist has become more picky about input files: whenever
343 it occurs something that is likely to result in bad output, it
344 issues a warning or an error.
346 - In case there should be any problems with the refactored codebase,
347 the "old" gnetlist is still available as "gnetlist-legacy".
349 * If gnetlist is invoked with the `pcbfwd' backend or the new option
350 `--report-gui', errors and warnings are displayed in a GUI dialog
351 instead of printing them to stderr.
353 * There are new semantics for power and I/O port symbols:
355 - Power symbols can now use a netname=NET instead of a net=NET:1
356 attribute. This allows using the attribute value as a visible
357 label, removing the need for power symbols for individual rails.
359 - I/O port symbols in subschematics can now use a portname=PORT
360 instead of a refdes=PORT attribute to distinguish them from
361 regular components. This allows checking that unconnected port
362 symbols aren't silently included in the netlist as components.
364 * Hierarchical schematics can now use a simple form of parametrization
365 where the instantiating component contains an attribute of the form
366 `param=NAME=VALUE' and some attribute value in the subschematic
367 contains the pattern `$(NAME)', which will be replaced with `VALUE'.
368 This only works with regular attribute lookup from netlist backends
369 and won't affect special attributes like slot= or netname=, though.
371 * The netlisting options "hierarchy-traversal", "net-naming-priority",
372 "unnamed-netname", and "unnamed-busname" are once again configured
373 via gnetlistrc, making them consistent with the refdes=, net=, and
374 netname= mangling options.
376 * Duplicate I/O ports in subschematics and duplicate I/O pins in
377 subschematic symbols are now treated correctly.
379 * Added a netlist backend for pcb-rnd's tEDAx format.
381 * Added backends which dump the netlist in various generic formats
382 (dumpindent, dumpjson, dumplihata, dumptext, dumpxml).
385 Notable changes in gEDA/gaf 1.9.2.1p
386 ====================================
388 * The gEDA/gaf source tarball no longer includes libintl. When
389 building gEDA/gaf with internationalisation support, a GNU
390 gettext-compatible libintl is now required.
392 * A new Scheme API function, `log!`, has been added to the `(geda
393 log)` module. It allows Scheme code to emit log messages in the
394 same way that the tools' C code does.
397 Notable changes in gEDA/gaf 1.9.2
398 =================================
399 * Build system changes:
401 - Guile 2.0 or newer is now required.
403 - top-level control file allowing continuous integration using
404 Travis CI has been added.
406 * Nullor expansion has been fixed in the `spice' and `spice-sdb'
409 - Element name prefix "E_" has been substituted for "E-" to prevent
410 errors output by some simulators (e.g. ngspice).
412 - A default gain value has been added in the nullor expansion code.
414 * Two obsolete scripts verilog2vhdl.sh and script.sed have been
417 * Undocumented and ambiguous feature of the `spice-sdb' backend for
418 gnetlist consisting in the possibility of using the "value="
419 attribute instead of "file=" only for include blocks and only in
420 embedding mode has been removed.
422 * The following scripts and programs have been moved from the `utils'
423 directory to a new `contrib' directory and are no longer installed
428 sarlacc_schem sarlacc_sym
429 pads_backannotate sw2asc
432 * `gpstoimage' has been removed from the distribution; equivalent
433 functionality is provided by the `gaf' command.
435 * `convert_sym.awk' has been removed from the distribution; equivalent
436 functionality is provided by the `convert_sym' command.
438 * gnetlist now supports output of netlists to the standard output.
440 * New Scheme procedures and hooks have been added. Please see the
441 "geda-scheme" info manual for more details.
443 - `set-component-with-transform!' is a modified version of
444 `set-component!', which applies all the specified transformations
445 to a component and immediately updates it.
447 - `auto-refdes-reset!' resets components' refdeses
449 - `copy-objects-hook' is called whenever an object is copied, it can
450 be used, for example, to reset component's refdes on copy.
452 * The following gschem configuration items have been added:
454 - `third-button-cancel' cancels draw actions by the third mouse
455 button in mousepan mode.
457 - `grid-mode' sets default grid mode.
459 * Fixes/updates to the *BSD, Mac OS X, and MinGW builds.
461 * Changes in the gschem UI event state machine:
463 - New drawing modes apply immediately.
465 - Indication of an action being in progress has been added.
467 - Mirror action can now be used during an object placement.
469 - Show/hide text function is now enabled during other actions.
471 - RMB panning is now enabled during placing or drawing.
473 * Some gschem dialog have been merged, made non-modal, and placed in
476 - Color, line, fill and pin type dialogs have been merged into one
477 non-modal object properties dialog with widgets applying values
480 - Text properties dialog.
482 - Options to control the magnetic net mode and the net rubber band
483 mode as well as grid mode and grid snap mode have been merged into
486 * The following dialogs/windows have been converted into an info bar
487 and are now placed in bottom notebook:
489 - Log (status) window.
493 * The following dialogs are now popup & docked the same way as the
494 execute script dialog:
496 - Show and hide text dialogs.
500 * Other gschem GUI changes:
502 - Hotkeys and menu items to show/hide the sidebar and status window
505 - Swatch for fill types has been added.
507 - Slot edit dialog now displays number of slots.
509 - Library folder structure in gschem is now displayed as tree.
511 - Indication of page change has been added in gschem main window's
514 * Improved find text functionality:
516 - When searching for text, gschem now descends all files specified
517 in the comma separated list of the source attribute.
519 - There is now a widget that lists all occurences of the text
520 objects that contain the search string.
522 - The find text operation does not switch the current schematic in
523 the view or interfere with the most recent page up.
525 - The find text operation also searches all open pages instead of
528 - The behavior of the find text operation works with multiple
529 toplevel windows open while running concurrent find text
532 - The find text operation can now use either a substring, pattern,
533 or regex. The pattern style uses * and ?. The regex uses glib,
534 which adheres to perl compatible regular expressions.
536 * Several symbols have been fixed/improved.
538 * gschemdoc has been enhanced to search in the user documentation
541 * Several translations have been added/updated.
543 * Man pages for gsymcheck and gschlas have been updated.

554 - SVG output bug in `gaf export'.
555 - Several other bugs.
558 Notable changes in gEDA/gaf 1.9.1
559 =================================
561 * Unbalanced overbar markers are now rendered correctly.
563 * Most tools now no longer set the GEDADATA or GEDADATARC environment
564 variables (they still obey them though).
566 * `gschem' now provides a path drawing tool, accessed using <A H> or
567 the "Add Path" menu item.
569 - Add a cusp node by left-clicking.
571 - Add a Bezier curve node by left-dragging from the node point to
574 - End the path by clicking on the same node point twice, or clicking
575 on the start node to close the path.
577 * On desktops that reparent menu bars (e.g. Ubuntu Unity) it is once
578 again possible to paste the clipboard using the menus.
580 * A number of `gschem' editing behaviour changes were made:
582 - Double-clicking on an entry in the "In Use" tab of the component
583 selector now behaves the same way as double-clicking in the
586 - When new attributes are attached to a net, they are placed at a 50
589 - The text color is now used as the default color for `pinlabel='
592 - Pin attributes are no longer automatically replaced when rotating
595 - It is possible to edit a text object even when other non-text
596 objects are selected.
598 - Control grips are now always drawn at the same on-screen size.
600 * The multi-attribute editor dialog in `gschem' has been extended to
603 - It now supports editing attributes of multiple selected
604 objects. These are aggregated into the dialog's attribute list.
606 Multiple attributes with the same name attached to any given
607 object are still shown in separate rows, but identically named
608 attributes from multiple selected objects will share a row. If a
609 row has differing values between objects, its value shows the text
610 "<various>" in a muted colour.
612 - Where an attribute is present in some, but not all selected
613 objects its name in the list is shown in red. A new popup menu
614 option allows copying such attributes to all selected objects.
616 - If no complex, placeholder, pin, net or bus objects are selected,
617 the dialog now falls back to editing any selected attribute text.
619 This allows editing of unattached or floating attributes in
620 symbols, or any attributes seleccted independantly of their owning
621 object. In this fallback mode, all attributes with the same name
622 shown in separate rows, and the "add attribute" functionality is
625 * `gschem' has new icons for many editing commands.
627 * Several bugs were fixed in `gnetlist':
629 - Invalid attributes are ignored.
631 - Correct detection of graphical symbols.
633 - Components with no `refdes=' attribute are reported.
635 - Crash fixes for `drc' and `switcap' backends.
637 * `gaf export' now accepts a `--scale' option.
639 * The `--size', `--margins' and `--align' options to `gaf export' can
640 now accept their multiple arguments separated with a space ` ', a
641 colon `:' or a semicolon `;'.
643 * `gaf config' now handles the `-p' option properly.
645 * `gnetlist', `gsymcheck' and `gaf' now output internationalised
648 * New Scheme procedures were added. Please see the "geda-scheme" info
649 manual for more details.
651 - The (gschem action) module contains procedures for working with
652 user editing actions (i.e. commands accessed via the menus or
655 - Two new hooks were added: `bind-keys-hook' is called whenever
656 keymap bindings are changed; `action-property-hook' is called when
657 action properties are changed.
660 Notable changes in gEDA/gaf 1.9.0
661 =================================
663 * A new schematic renderer library, `libgedacairo' has been added, and
664 all tools have been updated to use it. Related changes:
666 - The following configuration functions have been removed:
668 output-capstyle paper-sizes
669 output-color postscript-prolog
670 output-orientation print-command
671 output-type setpagedevice-orientation
672 paper-size setpagedevice-pagesize
674 - The following `gschem' configuration items have been added:
676 print-paper print-color
679 - `gschem' now generates PDF files rather than PostScript or EPS
682 - `gschem' now uses a standard GTK print dialog (with printer
683 selection, print preview, etc.)
685 * A new `gaf' command-line utility has been added. It provides a
686 number of subcommands:
688 - `gaf export' can be used to convert schematic files to PNG, SVG,
689 PDF, PS and EPS, with detailed control of paper size and margins.
690 It supports multi-page PDF and PS output.
692 - `gaf config' can be used to manipulate the project, user, and
693 system configuration stores (see below).
695 - `gaf shell' provides a Scheme REPL for batch manipulation of
696 schematic and symbol files.
698 * New project, user and system configuration stores have been added,
699 using a format similar to .desktop files. They can be manipulated
700 using the `gaf config' tool. Configuration parameters for most
701 tools will be converted to use this mechanism in future releases.
703 * The changes to highlighting of dangling net ends in gEDA/gaf 1.8.0
704 have been reverted. All dangling ends are once again flagged with a
705 brightly-coloured square.
707 * When editing a component with the `gschem' multi-attribute editor,
708 the dialog will now show the symbol name in its title.
710 * When using "Down Schematic" command in `gschem', an error message

1028 * Removed unimplemented "File->Open" feature in 'gattrib'.
1030 * Added --disable-gattrib command line flag to ./configure to disable the
1031 building of 'gattrib'. This is useful if you are building against
1032 gtk+ 2.17.x which breaks 'gattrib'.
1034 * 'gnetlist' does not recommend drc2 every time it runs. The drc2
1035 backend is only useful in certain circumstances.

1098 - The print and display color maps are now separate.
1100 - A new Scheme syntax is used to inspect and modify color maps.
1102 - If you wish to use a light background in `gschem', add the line:
1104 (load (build-path geda-rc-path "gschem-colormap-lightbg"))
1106 to your personal or project gschemrc file.
1108 * Attributes of embedded objects are now shown in the right color.
1110 * Bus pins are now supported by `gschem' and `libgeda', but are *not*
1111 properly supported by the netlister. The pin type can be modified
1112 by selecting a pin, then right-clicking it and selecting `Edit pin
1115 * All of the symbols were modified to use overbar markup tags ("like
1116 \_this\_") instead of separate lines.

1132 clicking anywhere in the bounding box.
1134 - The default mouse click distance required to select an element was
1135 increased to 10 pixels.
1137 - Double-clicking on a net segment selects all connected net
1140 * The percentage step in or out while zooming the display in `gschem'
1141 is now configurable with the `zoom-gain' gschemrc parameter. The
1142 default value is 20%.
1144 * The size of steps when panning with the mouse wheel or with a
1145 trackpad in `gschem' is now adjustable with the `scrollpan-steps'
1146 gschemrc parameter. The default setting scrolls in steps of 1/8 of
1149 * A number of improvements were made to the `gschem' component
1152 - The dialog now shows a table of top-level attributes in the
