Raw Blame History

/*
Best viewed with vim5, using ts=4
wmgeneral was taken from wmppp.
It has a lot of routines which most of the wm* programs use.

CHANGES:
---
14/09/1998 (Dave Clark, clarkd@skyia.com)
* Updated createXBMfromXPM routine
* Now supports >256 colors
11/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* Removed a bug from parse_rcfile. You could
not use "start" in a command if a label was
also start.
* Changed the needed geometry string.
We don't use window size, and don't support
negative positions.
03/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* Added parse_rcfile2
02/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* Added -geometry support (untested)
28/08/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* Added createXBMfromXPM routine
* Saves a lot of work with changing xpm's.
02/05/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* changed the read_rc_file to parse_rcfile, as suggested by Marcelo E. Magallon
* debugged the parse_rc file.
30/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* Ripped similar code from all the wm* programs,
and put them in a single file.
