Copyright (C) 1998-2019 gEDA Developers
This file documents important user-visible changes in gEDA/gaf. For
more information, please consult the `ChangeLog' file.
Notable changes in gEDA/gaf 1.10.0
==================================
General changes
---------------
* Added the library "xornstorage" and the Python package "gaf" as a
(currently quite minimal) way to access gEDA/gaf functionality from
outside of gschem. These are on the long term intended to replace
libgeda, making the core gEDA/gaf functionality available as a
library to both gschem and other applications.
* Added command-line tool `xorn' for low-level schematic and symbol
file manipulation.
* Added experimental XML file format (currently only supported by
gnetlist and the `xorn' command line utility).
* Objects colors are limited to 21 (up to and including FREESTYLE4).
More recent colors added for GUI purposes can be set in colormaps
but aren't automatically added to the file format specification.
* The symbol directories "gnetman", "verilog", and "vhdl" are now
installed to the new location PREFIX/share/gEDA/extra-sym/. This
allows adding the default library with "component-library-search".
* The directory to which gEDA programs write log transcripts can be
changed by setting the environment variable `GEDALOG' (the default
being ~/.gEDA/logs/).
* All tests now use the parallel test harness, speeding up `make
check' runs considerably when used with multiple jobs (-jN).
* Fixed bugs:
- lp-698501 gschem file preview function renders files twice
- lp-698524 gnetlist ignores duplicate inout-symbols
- lp-698768 No ordering requirement for attribute attach/detach
- lp-701637 gschem "Scheme Interaction" window
- lp-1266316 gschem exits on color value < 0
- lp-1367462 undo messes with the view even though undo panzoom is disabled
- lp-1492834 These docked dialogs should remember their size
- lp-1496899 gschem: dock window wishlist
- lp-1497659 gnetlist -v -g spice-sdb generates bad verbose netlist
- lp-1514209 gschem: multiattrib Value textview improvements
- lp-1532794 Build fails on missing colors.h
- lp-1576918 Memory and file handle leak in libgeda
- lp-1590757 partlist3 yields wrong netlist in some cases
- lp-1625474 xorn does not build on FreeBSD
- lp-1661961 "format not a string literal and no format arguments" warning
...and a lot more which never made it to the bugtracker.
gschem changes
--------------
* Tool windows are now "dockable", i.e., they can be either used as
modal/non-modal dialogs or docked to the edges of the main window.
* The action mechanism used for menu items, tool buttons, and key
bindings has been redesigned, making several improvements possbile:
- Actions can now be used interchangeably in the main menu, toolbar,
context menu, and keymap. They are defined in a single place
("actions.c" for C actions and "builtins.scm" for Guile actions),
including metadata like name, icon, and tooltip.
- Menu items and tool buttons representing options have a little
check or radio box beside them indicating their current state.
- Menu items and tool buttons are greyed out while they can't be
used.
- Toolbar and context menu are customizable.
- Menu and toolbar definitions are simple Scheme variables, allowing
users to add actions to the menu without having to copy the menu
definition. Actions are represented in Scheme code as applicable
SMOBs, allowing them to be called like procedures while retaining
the action information necessary for rendering the menus/toolbar.
- "Repeat Last Action" (usually bound to ".") uses the same logic as
the middle mouse button repeat action does, i.e., only actions
that "make sense" qualify for repeating.
* The menus, toolbar, and keymap have been revamped to more closely
resemble the "standards" for a desktop application. Some actions
have been assigned more accessible or memorable keys.
* Added a command-line option "--control-fd=stdin|FD" which allows
remote-controlling gschem via a file descriptor. This is intended
for project managers like Igor2's "genxproj".
* File operations have been consolidated: opening, saving, closing a
file and so on should now behave identical regardless of how the
operation was initiated. Related improvements:
- When opening multiple files, the first one (instead of the last
one) is initially shown.
- The symversion= mismatch dialog is shown whenever a symversion=
mismatch is detected while opening a file, not just for files
specified on the command line.
- gschem now keeps track of which files are untitled, listing them
as "untitled page" instead of assigning them a temporary filename.
The Scheme procedure `page-filename' returns #f for untitled
pages.
- "Save all" used to produce spurious "untitled_1.sch" files. This
was due to three issues working together, which have been fixed:
- When gschem is invoked without specifying filenames on the
command line, an untitled page is created. This page wasn't
removed when opening files, staying invisibly in the background.
- "Save all" didn't check which files needed saving but just
unconditionally saved anything.
- "Save all" didn't behave like the interactive "Save", asking for
a filename for untitled pages, but just saved each page to its
internally stored filename.
- The file chooser dialog on "Open" and "Save As" is now always
opened in the current directory.
- When opening a file which is already open but has since been
changed on disk, the user is asked whether to reload the file.
- When the currently edited file has been modified on disk, a
notification is shown offering the user to reload the file.
- If the user enters a filename with an unusual extension while
saving, a confirmation dialog is shown.
- When trying to open a file or descend into a subschematic which
doesn't exist, gschem now offers to create a new file with that
name.
* Some improvements have been made to the multi-attribute editor:
- Editing a single attribute invokes the multi-attribute editor.
- Trying to edit an inherited attribute edits the attached attribute
with the same name if it exists, or promotes the attribute and
edits its value if it doesn't exist yet.
- Attributes are shown in the order in which they are listed in the
configuration (via "attribute-name").
* Attaching and detaching attributes now work as expected:
- "Attributes / Attach Attributes" used to depend on the order in
which objects were selected, taking the first selected object as
the base object to attach attributes to, regardless of its type.
Now, the selected objects are searched for a base object of
suitable type, and only if exactly one is found, the attributes
are attached to it.
- "Attributes / Detach Attributes" used to work on selected
components and nets, detaching all attributes from these objects.
It now works on the selected *attributes*, allowing the user to
selectively detach specific attributes while leaving the rest
attached.
* "Lock Component" used to lock components as well as non-component
objects, bringing the latter into an invalid state that would last
until the next "Undo" (or until the page was saved and loaded back
from file manually).
This has been fixed: "Lock Component" and "Unlock Component" now
only operate on components, changing the color of attached
attributes as they used to do with any selected text.
* The "Light Color Scheme" (V L) selected from the menu now has a
truly white background. For compatibility, selecting the "lightbg"
colormap in gschemrc loads the old, light-gray color scheme; the new
color scheme can be selected as "whitebg".
* The library window has been made fit to be used as a dock window:
- When the dialog is resized to be taller than a certain aspect
ratio, it switches automatically to a stacked layout where the
preview and attribute panes are located below the symbol selector.
- While in stacked layout, the bottom panes can be expanded and
collapsed to give more room to the symbol selector.
- The window is automatically refreshed on library updates.
* Symbol editing has been improved:
- The page can now be scrolled to negative coordinates, making it
feasible to edit symbols without moving them away from the origin,
then translating them back. This also allows to consciously
choose something that makes sense for the symbol as the location
of the origin.
- The coordinate origin is now indicated with slightly darker grid
lines. (This can be enabled/disabled via "View / Show Origin".)
- The "Symbol Translate" action has been replaced with "Place
Origin" which lets the user select the position of the origin
interactively.
* Added support for back-annotation from pcb-rnd.
* Double-clicking a subschematic component enters the subschematic.
* Right-clicking in path mode works as expected.
* Pins are allowed to have zero length.
* "File / Revert" only asks for confirmation if the file has been
modified.
* The "repeat" function of the middle mouse button now evaluates
actions at the current mouse position.
* Mouse gestures work properly again.
* libstroke has been merged into gEDA/gaf. This removes the
dependency on libstroke and makes mouse gestures always available.
* Added new mouse gestures for page navigation:
- swiping left goes to the previous, swiping right to the next page
- swiping right and then down enters a subschmatic
- swiping left and then down enters a symbol
- swiping up and sideways (in any combination) goes back to the
parent schematic
* The coordinate dialog has been replaced with an option to display
the coordinates in the status bar.
* Added further menu items:
- "Add / Last Component" (A C)
- "Object / Toggle Text Overbar" (T O)
- "View / Show Menubar" (V M)
- "View / Show Toolbar" (V T)
- "View / Show Scrollbars" (V S)
- "Tools / Select Locked Objects" (T L)
* Fixed various issues related to undo/redo:
- The menu items "Edit / Undo" and "Edit / Redo" now show the name
of the action that will be undone/redone.
- The current viewport used to be restored on undo/redo regardless
of the "undo-panzoom" setting (which prevents pan and zoom
operations from being recorded in the undo history). This turned
out to confuse users, so if the setting is enabled, undo/redo now
doesn't change the viewport at all.
- The default mode ("undo-panzoom" disabled) now works correctly.
- After undoing the first action which changed a page, the page will
be considered "unchanged" again.
- Adding an attribute, changing the slot of a component, replacing
the contents of a picture, and selecting "Pan" from the menu used
not to be correctly un-doable. This has been fixed.
- Selecting a picture to be added doesn't cause the page to be
treated as changed any more.
- "Object / Update Symbol" can't be undone with the current undo/
redo system, so it isn't listed as something that can be undone
any more.
- Several actions (attach/detach attribute, text actions, embed/
unembed, lock/unlock component, show/hide specific text) changed
the undo history even in the case that they didn't have any
effect. This has been fixed.
- Several actions (attach/detach, embed/unembed) didn't update the
"changed" flag correctly; this has been fixed.
gnetlist changes
----------------
* Refactored gnetlist:
- gnetlist is now part of the Python package "gaf" and uses the new
libraries instead of libgeda to work with gEDA files.
- Netlist backends can also be written in Python.
- When reading broken schematics and/or symbols, gnetlist doesn't
silently fail or produce bad output any more. Conversely, this
means gnetlist has become more picky about input files: whenever
it occurs something that is likely to result in bad output, it
issues a warning or an error.
- In case there should be any problems with the refactored codebase,
the "old" gnetlist is still available as "gnetlist-legacy".
* If gnetlist is invoked with the `pcbfwd' backend or the new option
`--report-gui', errors and warnings are displayed in a GUI dialog
instead of printing them to stderr.
* There are new semantics for power and I/O port symbols:
- Power symbols can now use a netname=NET instead of a net=NET:1
attribute. This allows using the attribute value as a visible
label, removing the need for power symbols for individual rails.
- I/O port symbols in subschematics can now use a portname=PORT
instead of a refdes=PORT attribute to distinguish them from
regular components. This allows checking that unconnected port
symbols aren't silently included in the netlist as components.
* Hierarchical schematics can now use a simple form of parametrization
where the instantiating component contains an attribute of the form
`param=NAME=VALUE' and some attribute value in the subschematic
contains the pattern `$(NAME)', which will be replaced with `VALUE'.
This only works with regular attribute lookup from netlist backends
and won't affect special attributes like slot= or netname=, though.
* The netlisting options "hierarchy-traversal", "net-naming-priority",
"unnamed-netname", and "unnamed-busname" are once again configured
via gnetlistrc, making them consistent with the refdes=, net=, and
netname= mangling options.
* Duplicate I/O ports in subschematics and duplicate I/O pins in
subschematic symbols are now treated correctly.
* Added a netlist backend for pcb-rnd's tEDAx format.
* Added backends which dump the netlist in various generic formats
(dumpindent, dumpjson, dumplihata, dumptext, dumpxml).
Notable changes in gEDA/gaf 1.9.2.1p
====================================
* The gEDA/gaf source tarball no longer includes libintl. When
building gEDA/gaf with internationalisation support, a GNU
gettext-compatible libintl is now required.
* A new Scheme API function, `log!`, has been added to the `(geda
log)` module. It allows Scheme code to emit log messages in the
same way that the tools' C code does.
Notable changes in gEDA/gaf 1.9.2
=================================
* Build system changes:
- Guile 2.0 or newer is now required.
- top-level control file allowing continuous integration using
Travis CI has been added.
* Nullor expansion has been fixed in the `spice' and `spice-sdb'
backends.
- Element name prefix "E_" has been substituted for "E-" to prevent
errors output by some simulators (e.g. ngspice).
- A default gain value has been added in the nullor expansion code.
* Two obsolete scripts verilog2vhdl.sh and script.sed have been
removed.
* Undocumented and ambiguous feature of the `spice-sdb' backend for
gnetlist consisting in the possibility of using the "value="
attribute instead of "file=" only for include blocks and only in
embedding mode has been removed.
* The following scripts and programs have been moved from the `utils'
directory to a new `contrib' directory and are no longer installed
by default:
smash_megafile olib
gmk_sym convert_sym
sarlacc_schem sarlacc_sym
pads_backannotate sw2asc
gnet_hier_verilog.sh
* `gpstoimage' has been removed from the distribution; equivalent
functionality is provided by the `gaf' command.
* `convert_sym.awk' has been removed from the distribution; equivalent
functionality is provided by the `convert_sym' command.
* gnetlist now supports output of netlists to the standard output.
* New Scheme procedures and hooks have been added. Please see the
"geda-scheme" info manual for more details.
- `set-component-with-transform!' is a modified version of
`set-component!', which applies all the specified transformations
to a component and immediately updates it.
- `auto-refdes-reset!' resets components' refdeses
- `copy-objects-hook' is called whenever an object is copied, it can
be used, for example, to reset component's refdes on copy.
* The following gschem configuration items have been added:
- `third-button-cancel' cancels draw actions by the third mouse
button in mousepan mode.
- `grid-mode' sets default grid mode.
* Fixes/updates to the *BSD, Mac OS X, and MinGW builds.
* Changes in the gschem UI event state machine:
- New drawing modes apply immediately.
- Indication of an action being in progress has been added.
- Mirror action can now be used during an object placement.
- Show/hide text function is now enabled during other actions.
- RMB panning is now enabled during placing or drawing.
* Some gschem dialog have been merged, made non-modal, and placed in
sidebar:
- Color, line, fill and pin type dialogs have been merged into one
non-modal object properties dialog with widgets applying values
immediately.
- Text properties dialog.
- Options to control the magnetic net mode and the net rubber band
mode as well as grid mode and grid snap mode have been merged into
one options dialog.
* The following dialogs/windows have been converted into an info bar
and are now placed in bottom notebook:
- Log (status) window.
- Find text dialog.
* The following dialogs are now popup & docked the same way as the
execute script dialog:
- Show and hide text dialogs.
- Translate dialog.
* Other gschem GUI changes:
- Hotkeys and menu items to show/hide the sidebar and status window
have been added.
- Swatch for fill types has been added.
- Slot edit dialog now displays number of slots.
- Library folder structure in gschem is now displayed as tree.
- Indication of page change has been added in gschem main window's
title.
* Improved find text functionality:
- When searching for text, gschem now descends all files specified
in the comma separated list of the source attribute.
- There is now a widget that lists all occurences of the text
objects that contain the search string.
- The find text operation does not switch the current schematic in
the view or interfere with the most recent page up.
- The find text operation also searches all open pages instead of
the current one.
- The behavior of the find text operation works with multiple
toplevel windows open while running concurrent find text
operations.
- The find text operation can now use either a substring, pattern,
or regex. The pattern style uses * and ?. The regex uses glib,
which adheres to perl compatible regular expressions.
* Several symbols have been fixed/improved.
* gschemdoc has been enhanced to search in the user documentation
directory.
* Several translations have been added/updated.
* Man pages for gsymcheck and gschlas have been updated.
* Switches --help and -h have been added for most of gEDA utilities.
* Fixed the following bugs:

- 1463178: Gsch2pcb crashes when using `m4-pcbdir' option.
- 1478760: Gschem segmentation fault during find text.
- Gschem crashes on pressing the third mouse button.
- SVG output bug in `gaf export'.
- Several other bugs.
Notable changes in gEDA/gaf 1.9.1
=================================
* Unbalanced overbar markers are now rendered correctly.
* Most tools now no longer set the GEDADATA or GEDADATARC environment
variables (they still obey them though).
* `gschem' now provides a path drawing tool, accessed using <A H> or
the "Add Path" menu item.
- Add a cusp node by left-clicking.
- Add a Bezier curve node by left-dragging from the node point to
the control point.
- End the path by clicking on the same node point twice, or clicking
on the start node to close the path.
* On desktops that reparent menu bars (e.g. Ubuntu Unity) it is once
again possible to paste the clipboard using the menus.
* A number of `gschem' editing behaviour changes were made:
- Double-clicking on an entry in the "In Use" tab of the component
selector now behaves the same way as double-clicking in the
"Libraries" tab.
- When new attributes are attached to a net, they are placed at a 50
unit offset.
- The text color is now used as the default color for `pinlabel='
attributes.
- Pin attributes are no longer automatically replaced when rotating
or mirroring pins.
- It is possible to edit a text object even when other non-text
objects are selected.
- Control grips are now always drawn at the same on-screen size.
* The multi-attribute editor dialog in `gschem' has been extended to
support more cases:
- It now supports editing attributes of multiple selected
objects. These are aggregated into the dialog's attribute list.
Multiple attributes with the same name attached to any given
object are still shown in separate rows, but identically named
attributes from multiple selected objects will share a row. If a
row has differing values between objects, its value shows the text
"<various>" in a muted colour.
- Where an attribute is present in some, but not all selected
objects its name in the list is shown in red. A new popup menu
option allows copying such attributes to all selected objects.
- If no complex, placeholder, pin, net or bus objects are selected,
the dialog now falls back to editing any selected attribute text.
This allows editing of unattached or floating attributes in
symbols, or any attributes seleccted independantly of their owning
object. In this fallback mode, all attributes with the same name
shown in separate rows, and the "add attribute" functionality is
disabled.
* `gschem' has new icons for many editing commands.
* Several bugs were fixed in `gnetlist':
- Invalid attributes are ignored.
- Correct detection of graphical symbols.
- Components with no `refdes=' attribute are reported.
- Crash fixes for `drc' and `switcap' backends.
* `gaf export' now accepts a `--scale' option.
* The `--size', `--margins' and `--align' options to `gaf export' can
now accept their multiple arguments separated with a space ` ', a
colon `:' or a semicolon `;'.
* `gaf config' now handles the `-p' option properly.
* `gnetlist', `gsymcheck' and `gaf' now output internationalised
messages.
* New Scheme procedures were added. Please see the "geda-scheme" info
manual for more details.
- The (gschem action) module contains procedures for working with
user editing actions (i.e. commands accessed via the menus or
keybindings).
- Two new hooks were added: `bind-keys-hook' is called whenever
keymap bindings are changed; `action-property-hook' is called when
action properties are changed.
Notable changes in gEDA/gaf 1.9.0
=================================
* A new schematic renderer library, `libgedacairo' has been added, and
all tools have been updated to use it. Related changes:
- The following configuration functions have been removed:
output-capstyle paper-sizes
output-color postscript-prolog
output-orientation print-command
output-type setpagedevice-orientation
paper-size setpagedevice-pagesize
- The following `gschem' configuration items have been added:
print-paper print-color
print-orientation
- `gschem' now generates PDF files rather than PostScript or EPS
files.
- `gschem' now uses a standard GTK print dialog (with printer
selection, print preview, etc.)
* A new `gaf' command-line utility has been added. It provides a
number of subcommands:
- `gaf export' can be used to convert schematic files to PNG, SVG,
PDF, PS and EPS, with detailed control of paper size and margins.
It supports multi-page PDF and PS output.
- `gaf config' can be used to manipulate the project, user, and
system configuration stores (see below).
- `gaf shell' provides a Scheme REPL for batch manipulation of
schematic and symbol files.
* New project, user and system configuration stores have been added,
using a format similar to .desktop files. They can be manipulated
using the `gaf config' tool. Configuration parameters for most
tools will be converted to use this mechanism in future releases.
* The changes to highlighting of dangling net ends in gEDA/gaf 1.8.0
have been reverted. All dangling ends are once again flagged with a
brightly-coloured square.
* When editing a component with the `gschem' multi-attribute editor,
the dialog will now show the symbol name in its title.
* When using "Down Schematic" command in `gschem', an error message
will now be displayed if the subcircuit schematic cannot be loaded.
* Printing now uses a light background color map by default.
* Objects can now have the line end "cap style" adjusted in `gschem'.
* `gnetlist' now accepts the `-i' and `-g' command-line arguments
together. If you specify both `-i' and `-g', `gnetlist' will enter
the Scheme REPL after loading the requested backend but before
executing it.
* `gattrib' now has translations for the user interface and various
messages.
Notable changes in gEDA/gaf 1.8.2
=================================
Bugfix release.
* [994361] Fixed a libgeda crash bug involving nets inside symbols.
* [1226246] Fixed a gnetlist data corruption bug when using refdes
containing the string "POWER".
* Updates to build system to allow compilation from git on systems
with Automake >= 1.13.0.
Notable changes in gEDA/gaf 1.8.1
=================================
Bugfix release with correct dynamic version information for libgeda.
Notable changes in gEDA/gaf 1.8.0
=================================
* `gschem' and `gnetlist' have updated and rewritten user guides.
* All tools now give more informative error messages if they are
unable to load schematic or symbol files due to syntax errors.
* All tools now correctly handle schematic and symbol files with `\r',
`\n', or `\r\n` line endings, or a mixture.
* Unconnected pin ends and net ends are now all drawn with the same
box marker in `gschem' and printed output.
* Net segments with at least two connections (including indirect
connections via `netname=' attributes) are now drawn with arrowheads
rather than box markers on dangling ends in `gschem' and printed
output.
Notable changes in gEDA/gaf 1.7.2
=================================
* `geda-gaf' now requires GTK+ 2.16.0 or later.
* A greatly expanded Scheme API has been added to gEDA/gaf for use by
extension authors. See the `geda-scheme' Info manual for more
details. Existing extensions may need to be modified to load the
`(geda deprecated)' or `(gschem deprecated)' modules.
* The `component-library-search' function for `gafrc' files now skips
directories without symbols, and searches for libraries recursively.
* `gschem' keybinding improvements:
- Keybindings are now unaffected by Caps Lock.
- Keystrokes are displayed using the same characters as on keycaps
(e.g. `:' instead of `colon').
- Keystrokes may use extended modifiers (Super, Hyper and Meta).
- Key bindings can be modified in any rc file or interactively using
the `global-set-key' function. See notes in `system-gschemrc' for
examples.
* `gschem' now displays help files and component documentation on all
platforms, including Windows. The `locate' tool is no longer used
to search for component documentation files.
* The `schdiff' tool for generating visual diffs of schematics and
symbols has been added. It can be used with most version control
systems. See `man schdiff' for more details.
* The `bom' and `bom2' backends to `gnetlist' now give error messages
if no attribute file can be found. The `-O attrib_file=FILE' and
`-O attribs=ATTRIB,ATTRIB...' options have also been added.
* A new `ewnet' backend has been added to `gnetlist'. This outputs
netlists for use with the National Instruments ULTIboard layout
tool.
* The `verilog' backend to `gnetlist' now supports concatenated net
naming like "{a,b,c[3:0]}".
* `gsch2pcb' no longer supports the `m4_command' parameter in project
files.
* The `--m4-pcbdir' and `--m4-file' arguments to `gsch2pcb' now work
again.
* `gsymfix.pl' has been renamed to `gsymfix'.
* Man pages are now available for all programs installed as part of
gEDA/gaf.
* The undocumented programs `gnet_hier_verilog', `gsymupdate', `gschupdate'
and `sch2eaglepos.sh' are no longer installed to ${prefix}/bin.
Notable changes in gEDA/gaf 1.7.1
=================================
* gEDA is now compatible with Guile 2.0.
* gEDA/gaf applications no longer complain when trying to load an rc
file twice, or when an rc file doesn't exist.
* `gschem' allows objects to be moved by dragging without having to
select them first.
* `gschem' now supports keybindings with more than one modifier key,
and "Deselect" is bound to <Control Shift A> by default.
* `gnetlist' correctly handles multiple renames of the same net. This
resolves some long-standing bugs with multipage schematics.
* The `spice-sdb' backend for `gnetlist' now has built-in support for
`SUBCKT_NMOS' and `SUBCKT_PMOS' devices.
* A new `makedepend' backend has been added to `gnetlist'. It
generates Makefile code for SPICE simulation dependencies.
* Visibility of embedded component attributes are now preserved by
`gattrib'.
* `gsch2pcb' correctly handles footprint names with hyphens (`-').
* `gsch2pcb' project files support quoting and escaping in
`schematics' entries.
* Considerable enhancements to Unicode support when printing
schematics or exporting PostScript.
Notable changes in gEDA/gaf 1.7.0
=================================
* All gEDA/gaf applications now handle configuration files much more
strictly, and provide much more useful feedback when an error
occurs.
* Several changes to `gschem' command-line options:
- The `-t' option is no longer supported.
- Several command-line options now support a long-form alternative.
- The `-s' option can now be used to run multiple Scheme scripts
during `gschem' startup.
- A new `-c' option is available, which runs a Scheme expression
during `gschem' startup.
- A new `-L' option is available, which adds a directory to the
Scheme load path.
- A new `-V' or `--version' option is available, which displays
version information.
* `gschem' now provides a "Select All" function, which is bound to
<Control a> by default, along with a corresponding "Deselect"
function.
* In the `gschem' "Add component" dialog, filtering the component
library will expand matching libraries. If the filter is cancelled,
all libraries are collapsed. Components can now be selected by
double-clicking on them in the component list.
* The `gschem' "Edit Text Properties" dialog now has an easier to use
"Alignment" menu.
* Printed text size now better matches on-screen text size in
`gschem'.
* Special characters, including commas, are now escaped or quoted
appropriately in `gattrib' CSV output.
* Several changes to `gnetlist' command-line options:
- Four command-line options specific to the `spice-sdb' backend have
been removed. They can be replaced with `-O <option>' according
to the following table:
-e, --embedd -O embedd_mode
-I, --include -O include_mode
-n, --nomunge -O nomunge_mode
-s, --sort -O sort_mode
- The list of available backends is now obtained using a new
`--list-backends' option. `-g help' no longer outputs a list of
backends.
- A new `-L' option is available, which adds a directory to the
Scheme load path.
- A new `-V' or `--version' option is available, which displays
version information.
- When run with invalid command-line arguments, `gnetlist' now exits
with non-zero exit status.
* Several `gnetlist' backends have now been fixed so that it should no
longer be necessary to set an expanded Guile stack in gEDA's config
files.
* The `spice-sdb' backend for `gnetlist' now supports probes
(`TESTPOINT' devices).
* The undocumented `mk_verilog_syms' program is no longer installed.
The symbols it creates are still installed to
`${prefix}/share/gEDA/sym/verilog'.
Notable changes in gEDA/gaf 1.6.2
=================================
* PNG export from `gschem' will now be cropped correctly.
* The `partlist' backends for `gnetlist' now handle hierarchical
refdes correctly.
* On Windows, `gschem' and `gattrib' will no longer launch with a
command window visible.
* `gnetlist-arg' is no longer valid in `gsch2pcb' project files.
Several other bugs were fixed, including a major crash bug in
gnetlist.
Notable changes in gEDA/gaf 1.6.1
=================================
* Added accelerator mnemonics for root menus in gschem
* Lots of updated and new language translations in libgeda, gschem, and
gattrib. (Courtesy of language translators and Launchpad)
* Updated the shipped documentation from the official gEDA wiki
* Fixed the following bugs:
- 2876373: Fix rendering with zoomed out dashed lines
- 2901183: Fix for some manpage issues
- 2904715: Don't update page connectivity from o_place_rotate()
- 2949232: Fix slot editing routines to not edit inherited attributes
- Cherry picked some other bug fixes from master that should be in
this release
Notable changes in gEDA/gaf 1.6.0
=================================
* Fixed the GtkItemEntry code inside of gattrib code so that it builds
using gtk+ > 2.16.x.
* In gschem, rubberband pin to pin connections by adding nets.
* Cleanup of the slot handling code in libgeda.
* Fixes/updates to the MinGW port.
* Updated the shipped documentation from the online wiki.
Notable changes in gEDA/gaf 1.5.3/1.5.4
=======================================
* NOTE: gEDA/gaf 1.5.3 was released with some critical bugs, so
it was withdrawn before it was widely distributed.
* Text rendering using native system fonts:
- The various programs in gEDA/gaf no longer uses its own built-in
line font.
- Native system fonts are used for rendering, giving support for a
wider range of symbols, and better looking schematics.
* Always use PostScript fonts in gschem's PostScript output. The
"output-text", "text-output" and "output-vector-threshold" config
functions have been removed.
* Image rendering in 'gschem' uses cairo instead of GDK.
* Numerous build system changes:
- gEDA/gaf is now distributed as a single source archive, called
gEDA-<version>.tar.gz.
- GTK+ 2.10 or newer and Guile 1.8 or newer are now required.
- `intltool' is no longer required.
- Documentation is now installed to ${docdir} (usually
${prefix}/share/doc/gEDA).
* The attribute edit dialog in `gschem' now has completion of most
common attribute names.
* The multi-attribute edit dialog in `gschem' now shows unpromoted
symbol attributes.
* Menu items in `gschem' now have icons and properly aligned key
bindings. They also support accelerator keys.
* The `gschem2pcb' and `PCBboard' netlist backends have been removed.
It is recommended to use `gsch2pcb' instead.
* Check for and reject non-footprint PCB files in 'gsch2pcb'.
* Removed unimplemented "File->Open" feature in 'gattrib'.
* Added --disable-gattrib command line flag to ./configure to disable the
building of 'gattrib'. This is useful if you are building against
gtk+ 2.17.x which breaks 'gattrib'.
* 'gnetlist' does not recommend drc2 every time it runs. The drc2
backend is only useful in certain circumstances.
* Assign shortcuts "vd" and "vl" for changing between color schemes
in 'gschem'.
