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. |
