Release notes for the gEDA/gaf 20050313 snapshot
Changes
_________________________________________________________________
general
* Lots and lots and lots of code cleanup, refactoring, and bug
fixing by Patrick Bernaud, Stuart Brorson, Carlos Nieves Onega,
Werner Hoch, and Dan McMahill. This applies to all parts of
gEDA/gaf. The amount of cleanup is quite staggering, so please
look at the various ChangeLogs for more info. Many thanks to all
who lent a hand in this rather difficult task!
libgeda
* Shared library version number now at 23.
* Carlos added proper unicode support to libgeda. Schematic and
symbol files can now have unicode characters in them and as long
as there is a font definition file for them, the characters will
appear in gschem. This was the last piece for making the
transition over to gtk+ 2.2.x. Patrick did some misc cleanup on
the unicode support as well.
* Patrick rewrote the logging mechanism to use GLib's message
logging.
* Carlos added picture support to libgeda. This allows users to put
pictures in various formats into schematics. Pictures are not yet
rendered in postscript or png files. This feature will be
completed in a subsequent release.
* Dan added electric fence support to all configure scripts.
* Dan squashed a whole bunch of gcc warnings as well turning on
-Wall by default to further point out developer laziness. :)
* Patrick rewrote the all guile code to use the 1.6.x scm
interfaces. Dan and Carlos did some minor touch up to catch other
missed deprecated guile interfaces.
* Patrick rewrote the component library code to be sane.
* Stuart added code to read in rc files when a schematic file is
loaded from a foreign directory. This allows users to open up
schematics that have local symbols.
* Stuart add code for of a component placeholder for when a
component cannot find its symbol file. This was extended a little
to draw a graphic informing the user which component is missing
its symbol file.
* Fixed the symversion= code handling to deal with the case when no
other attributes are attached to the component. In the past, this
scenario was simply ignored.
* Added code (temporarily till the bug is fixed) which forces
libgeda to output the vector font when rendering multi-line text
items. This behavior can be controlled via the gschem rc keyword:
output-vector-threshold
gschem
* Werner Hoch completely rewrote the Attributes/Autonumber Text...
dialog box. This new dialog boxes fixes some of the past problems
and hopefully will satisfy more users given that it has far more
capability than the last dialog box.
* Patrick completely rewrote the multi attribute dialog box. This is
a significant change which really improves the usability of this
dialog box. Other than just being a major visible improvement,
there are other features: you right click on the attributes
themselves to Delete or Duplicate them and you can enter
multi-line attributes by hitting Control-Enter instead of enter.
* Bert Timmerman contributed an updated Dutch translation.
* Iznogood contributed the first versions of the French translation.
* Carlos added the first versions of the Spanish translation.
* Carlos went through all the code and gave them all stock pretty
stock icons.
* Patrick completely rewrote the page manager to be sane.
* Stuart improved the right mouse button pop up menu to include a
few more commonly used options.
* Handsom Greg supplied a patch to allow gEDA/gaf to build using
gtk+ 2.6.x.
* Patrick removed any limitations on number of files in the
component library code.
* Part of Stuart's work on reading in rc files in different
directories, system-commonrc was renamed to system-gafrc.
* Patrick rewrote most of the code for the line type and fill type
dialog boxes. They can now be used for multiple objects.
gnetlist
* Carlos modified the bom, bom2, drc2, and redac backends to write
to stdout if a "-" is specified using the -o flag.
* Dan added several guile functions to deal with target netlist
refdes requirements which may be more restrictive than
gschem/gnetlist. Dan also updated his futurenet2, pads, and
switcap backends to use these new functions.
* Carlos improved his drc2 backend to check for duplicated
references as well as properly return exit codes to allow gnetlist
to be used in Makefiles easily.
* Carlos added several functions for use in the DRC backend.
gattrib
* Stuart made a bunch of bug fixes and improvements including:
* Added a pop-up window if a component is found with no symbol file.
* Fixed a bug where only one page of design was searched for missing
attribs.
* Fixed bug where pre-existing attribs were deleted instead of being
replaced.
* Added support for slotted components.
gsymcheck
* Carlos added a check of the pintype attribute value.
* No other significant changes except a bunch of code cleanup and
updating.
symbols
* Carlos and Patrick made the necessary changes support unicode
characters in gEDA/gaf. Wojciech Kazubski also contributed Polish
font definitions.
* Stuart added a bunch of SPICE symbols.
* Werner Hoch did a considerable amount of fixing of various broken
symbols. Many thanks.
geda (gManager)
* Applied segfault patch by Werner Hoch.
* Added updated Italian translation by Marco Colombo.
* No other significant changes except a bunch of code cleanup and
updating.
utils
* Stuart added additional printfs to gsch2pcb during directory
search when using the -v -v flags.
* No other significant changes except a bunch of code cleanup and
updating.
docs
* The gsch2pcb tutorial was updated to the latest version.
* Carlos updated the file format document to describe the new
picture object.
examples
* Stuart updated some of the schematics in the RF_Amp example.
For more a detailed changes, please look in the appropriate ChangeLogs
in the source tarballs.

Release notes for the gEDA/gaf 20041228 snapshot
Changes
_________________________________________________________________
libgeda
* Shared library version number now at 22.
* Added a new attribute: symversion= and associated mechanism to
libgeda.
+ The symversion= mechanism allows symbols to be versioned with
a major and minor number. An example of this attribute is
symversion=1.0
+ This symversion= attribute is typically found in symbol files
at first, but it will be promoted if it is found when the
symbol is read in from disk.
+ The symversion= attribute is an auto-prompted attribute,
which if present in a symbol will always be promoted to the
schematic.
+ If the major number of the symversion= attributes (the one in
the symbol and the one in the schematic) does not match, then
a serious warning message is issued.
+ When a user changes a symbol file in a major or incompatible
way (translation, addition/removal of pins/attributes
etc...), the major number of the symversion= attribute value
should be incremented by one.
+ For minor changes, primarily cosmetic changes, only the minor
number of the symversion= attribute value should incremented
by one.
+ If the minor number of the symversision= attributes (the one
in the symbol and the one in the schematic) does not match,
then a minor warning message is issued.
+ The default value is 0.0 even if no symversion= attribute is
present.
* Fixed the randomly colored midpoint postscript bug reported by
Gabriel Paubert. Also removed some redundant code related to
postscript printing.
* Moved a whole bunch of rc routines from gschem/gnetlist/gsymcheck
into libgeda. This makes using the common rc code much easier.
* Added the --with-rcdir ./configure flag to libgeda. This was
required because of the above rc code refactor. You must
./configure libgeda with this flag if you intend to move the rc
files to a different directory. Be sure to put this flag on all
programs (gschem/gnetlist/gsymcheck/gattrib etc...) if you want to
move the rc files.
* Part of the above rc code refactor was to add an additional rc
file: gafrc. The gafrc file is read in last after all other rc
files are read in. Only common rc keywords can be put inside the
gafrc file, including:
+ component-library
+ component-library-search
+ source-library
+ source-library-search
+ world-size
+ reset-component-library
+ reset-source-library
+ default-series-name
+ untitled-name
+ scheme-directory
+ bitmap-directory
+ font-directory
+ bus-ripper-symname
Now you do not have to create a gschemrc, gnetlistrc, gattribrc,
gschlasrc etc... if you are just adding custom component
libraries. Just create a gafrc file and put the library lines in
there.
* Added a bunch of init function to libgeda_init() to make using
libgeda a little easier.
gschem
* Added a dialog box which pops up when a schematic is loaded up
which has components which have changed in a major or minor way
(based on the new symversion= attribute). See above the libgeda
section for a description of the new symversion= attribute and its
usage.
* Hopefully finally fixed the broken postscript problem when the
locale uses commas instead of periods. Original fix by Bill Wilson
and patch by Andreas Fester.
* Fixed a gschem crash when certain components (depending on what
was connected to them) were being updated. I have also started
working on fixing Edit/Component Update... to be more sane (and
not cause duplicated attached attributes). This work is not
complete, and for now, Edit/Component/Update... will still cause
duplicate attributes.
* Fixed some visual garbage/corruption in the preview window in the
file selection and component place dialog boxes.
* Added a new rc keyword "grid-dot-size" which lets you control the
size of the grid dots. Handy if the dots are too small to see.
* Applied the scroll wheel pan patch by Sascha Silbe. The scroll
wheel pans the display vertically and holding down the control key
and moving the wheel the will scroll the display horizontally.
* Added a modal "Are you sure?" dialog box to page revert. This
should prevent accidental page reverts (cause work losses). This
dialog box is only implemented for gtk+ 2.x
* Added an Italian translation by Petrecca Michele.
* Added the comment and symversion attribute to the attribute
pulldown list in the Add/Attribute dialog box.
* Updated gschem with the newly refactored rc code.
gnetlist
* Stuart implemented a whole slew of improvements to the spice-sdb
backend.
* Stuart added several functions to passing the command line to
scheme backends.
* Removed gschem2pcb as an installed program. gsch2pcb is the
preferred tool for going from schematic to PCB.
* Applied a bugfix patch to the cascade backend by Dan McMahill.
* Integrated the initial version of a SystemC backend by Jaume
Masip.
* Integrated a new scheme backend for Eagle PCB. The backend was
written by Braddock Gaskill.
* Updated gnetlist with the newly refactored rc code.
gattrib
* Integrated Stuart Brorson's attribute editor: gattrib into
gEDA/gaf. This is the first gEDA/gaf release that includes
gattrib.
* Here's a description of gattrib:
Gattrib is gEDA's attribute editor. It reads a set of gschem .sch
files (schematic files), and creates a spreadsheet showing
all components in rows, with the associated component
attributes listed in the columns. It allows the user to add,
modify, or delete component attributes outside of gschem, and
then save the .sch files back out. When it is completed, it
will allow the user to edit attributes attached to
components, nets, and pins. (Currently, only component
attribute editing is implemented; pin attributes are
displayed only, and net attributes are TBD.)
gsymcheck
* Integrated a patch by Jim Duchek which adds several more useful
tests to gsymcheck.
* Updated gsymcheck with the newly refactored rc code.
symbols
* Redrew the following symbols and set the symversion= attribute to
1.0:
4000/4002-1.sym 4000/40107-1.sym 4000/4011-1.sym 4000/4012-1.sym
4000/4023-1.sym 4000/4025-1.sym 4000/4030-1.sym
4000/4068-1.sym 4000/4070-1.sym 4000/4072-1.sym
4000/4073-1.sym 4000/4075-1.sym 4000/4078-1.sym
4000/4081-1.sym 4000/4082-1.sym 4000/4085-1.sym:
If you have any of these symbols in any existing schematics, you
should get a warning that major changes have occurred when you run
gschem or gnetlist.
* Added over ~100 user contributed symbols to the various component
libraries. Created 5 new component libraries: minicircuits st apex
allegro irf
* Moved the local component library to the beginning of the search
order.
* Updated Peter Kaiser's asic library with the latest set of symbol.
Added Peter's asic pad symbols into the new asicpads library.
Commented in the asic library now that the symbol names are
unique.
* Werner Hoch has fixed a whole slew of symbols in various component
libraries (74, 4000, and memory). Thanks Werner!
geda (gManager)
* Piotr Miarecki added graphman, a new tool for managing graphs.
* Piotr update gManager to build with gtk+ 2.2.x
* Integrated a French and Italian translation. Not sure if the
translations are work yet.
utils
* Added symbol cleanup (gsymfix.pl) script by Mike Skerritt.
* Updated gschlas with the newly refactored rc code.
docs
* attributes and symbols documents: Added information and details on
the symversion= attribute
* toplevel doc page: Added links to SystemC and Eagle backend
READMEs.
