|---||09/10/08||use git repository||---||---||Piglet's complete source tree is now cloneable with the git(1) revision control system. Follow the link on the left to the git repository. There are options to clone the entire database (about a megabyte), or to download a tar or zip of the latest version.|
|0.95e||08/15/08||piglet2008-08-14.tar.gz||259190||alpha||The SET command is implemented. Piglet now inheirits environment variables from its parent process. SET with no arguments will print all ENV variables. SET with one argument will print the value of the named variable. SET with two arguments will set the value of the named variable. Piglet now uses the PATH variable when parsing commands. If the command is not an internal Piglet command, then it will be searched for in the PATH definition. If a UNIX executable is found in the PATH will be run with the standard output sent to the Piglet text window. Any variables that you SET inside piglet will be accessible inside the subshell with $VARNAME. Replaced getline() with fgets() function to make the code run on Solaris.|
|0.95d||02/11/07||piglet2007-02-11.tar.gz||256000||alpha||Commas are now optional between coords. You can type "ADD R1 0 0 1 1;". Rebuilt all command parsers to use new getnum() routine in token.c, reducing code size by about 1000 lines. WIN :Z redraws the previous window. Fixed bug that caused double-wrapped instances to be deleted. Recursive EDI only asks if you want to reread a copy if the current copy in memory is modified. IDE prints out a line that can be cut/pasted. SMA now has a recursive option :R and a point option :P. :P is the default, but :R lets you smash many things at once by region. This is a developer's release. Write me if you want a copy.|
|0.95a||01/19/07||piglet2007-01-19.tar.gz||256000||alpha||Fixed UNDO problem caused by bug in OPT checksumming code. Added question when re-EDIting an unSAVed cell: "Cell already in memory, read in a new copy?: (y/n)?"|
|0.95||01/13/07||piglet2007-01-13.tar.gz||256000||alpha||Unlimited UNDO/REDO command. Works with all commands that change the drawing. A bit-for-bit copy of the cell database structure is pushed on a stack after every change. Each cell has it's own set of UNDo/REDo stacks. Changes to cells are automatically detected with a simple hash function.|
|0.94d||12/31/06||piglet2006-12-31.tar.gz||256000||alpha||Last release of the year! Fixed a double-free memory problem that cause a repeatable core dump. Added a new zooming mechanism for people without wheel-mice. Click on a point with the middle button, move right with the button down to zoom in and left to zoom out. Some further improvements to stipples and line types. Better default process file. Thanks to Mark Mathews for the zoom suggestion!|
|0.94c||11/21/06||piglet2006-11-21.tar.gz||256000||alpha||Mostly a bug-fix release, however better stipple fill patterns are available. EQU command has new :F option for specifying fill patterns. :F0 is unfilled, :F1 is solid fill, :F2 is 45 degree lines, etc. Better line,arc drawing. Each shape is a complete polygonal outline without the construction lines present in previous versions. Lines, Arcs now fill properly. Please let me know if you are using Piglet. It is the only thing that motivates me to keep posting updated code.|
|0.94||10/19/06||piglet.2006.10.19.tar.gz||256000||alpha||Mouse wheel zooms and pans even while adding a line or polygon. Fixed subtle clipping problem with Sutherland/Hodgman algorithm. Text is now filled properly with "WIN :O". Added RAW mode for tokenizer as a step towards on-screen text editing. Added GPL "COPYING" file and initial start-up screen license notice. Makefile now builds dependencies automatically. SAVE code behaves more nicely when there is a permissions problem in the cells directory. Removed redundant manpage installation code in ./man/makemans script.|
|0.93||09/19/06||piglet.2006.09.19.tar.gz||225280||alpha|| STRetch command works with regions, CHA applied to TEXT, NOTES puts the selected
text into the command line history buffer. DEL by region (:R) works. Better
HELp messages (gives syntax synopsis). Spent some time with valgrind program closing
several memory leaks. Valgrind is great! ADD NOTE and ADD TEXT have :J|| 0.92
|| STRetch command can change vertices of arcs, lines, polys, rects and adjust
circle diameters. It defaults to MOV behavior for text, notes and
instances. STRetch by region will be in next release.
Both MOVe and COPy have :R and :P options to allow move and copy by region. Default is by point.
WIN :O toggles polygon filling. All postscript output goes through the Cohen-Sutherland clipper routine so that zoomed drawings are efficiently represented in the postscript file.
WRAP is working. SMAsh is working. If wrapped region is not named, a "NONAME_nnn" instance is automatically created. Wrapped instances can be rotated, scaled and mirrored. When a cell is saved, the anonymous NONAME instances are automatically SMAshed to disk.
TIME/DATE TSLANT and FSIZE commands working.
BACKground command allows adding an overlay instance for comparison or to make a form.
DIStance command now prints out angle in degrees between two points.
QUICKSTART: type "make" to build binary, type "make install" (as root) to install man pages and library. run "pig" to start the editor. Inside piglet retrieve an example house floorplan drawing from it's archive file with "ret PLAN;" Type "edi PLAN;" to edit the floor plan drawing. Do a window fit command to see the whole drawing "win :F;". To play around with making changes, first unlock the drawing for modification with "SHO #E;" (make Everything readable/writable (#)). Now you can add lines with "ADD L<layer> x1,y1 x2,y2...;", or other components. Remember that all commands must end in either right mouse click, a ";" character, or the name of another command. There are a few other archives inside the cells directory. The archive files have "_I" as a suffix, the unpacked devices have ".d" as a suffix. You can unpack them in the same way as PLAN. For instance, retrieve "smorgasboard" by typing "ret smorgasboard;". You can then edit the cell with "edi smorgasboard;". Have fun!
|| EQUate command is working, allowing process layers to be defined with specific
fill colors, line types, names and properties. Process definitions are now stored in
the file PROCDATA.P. All configure files, including fonts, menus and process definitions
are searched for and loaded using a defined PATH.
Default PATH is .:./.pigrc:~/.pigrc:/usr/local/lib/piglet:/usr/lib/piglet.
Piglet is now usable as a general editing tool from any directory.
|| Polygon filling and clipping using Sutherland-Hodgman algorithm.
Initial ARC support. Many bug fixes. Now compiles clean with "gcc -Wall".
Archive file format now includes "$FILES:" command, purging all defined
files prior to archive retrieval. Version 0.7 had unusable example archives.
Release 0.8 has several current, working archives in the ./cells directory.
After saving the .gz file, run "tar zxvf pig.08.tar.gz". You can then run "pig"
and retrieve any of the "<file>_I" archive files in ./cells by typing "RET <file>".
The files will be read in and you can take a look by typing "EDI <file>". You
may want to fit the design to the current window with "WIN :F;" and then unlock
all layers for editing with "SHO #E;". Have fun!
I removed the RCS files and the generated documentation files from the release
to reduce the size. Please contact "walker AT omnisterra DOT com" if you need
|| Nested edits work. DUMp automatically tops the graphic window.
CHAnge can modify all options of any component. GRId now can be any
multiple of the resolution (hardwired at the moment to 0.01). Menu
is user customizable and working. AREa command is working. LOCk angle
is enforced when adding lines.

contains RCS files and screenshots).
