+ansistatuscolors
+by la11111
+
+updated 11.12.12 - squashed my code together to
+patch better across versions - killed remaining memory
+leaks. removed some useless junk.
+
+put ansi escape codes in your status bar output to
+change the color. Note: full ansi spec not implemented
+at the moment. incorrect codes are ignored, even if they
+may be valid ansi codes (ie, changing up the order or something)
+
+*** escape code format:
+
+\e[<code>m
+
+ \e - ascii 27, hex 0x1b, octal 033
+ [ - literal bracket
+ m - literal 'm'
+
+*** codes supported:
+
+standard escape codes:
+
+n;m
+ n -
+ 0 - normal
+ 1 - 'bright'
+ m -
+ 30-37 - text foreground
+ 40-47 - text background
+
+0 -
+ reset formatting to default
+
+example (python):
+ print "\x1b[1;31mHello World!\x1b[0m"
+
+256-color escape codes (xterm):
+
+n;5;m
+ n -
+ 38 - text foreground
+ 48 - text background
+ m -
+ 0-15 - alias classic ansi colors
+ 16-231 - rgb grid color
+ 232-255 - grayscale ramp color
+
+example (python):
+ print "\x1b[38;5;196mHello World!\x1b[0m"

Or you can just use the patch command as suggested by @la11111 at http://dwm.suckless.org/patches/ansistatuscolors.

I'm working on an integration with current master but it needs a pretty thorough rewrite thanks to http://git.suckless.org/dwm/commit/?id=5364697914fd4272fc1a6494b4fc522d2935427a.

@la11111 Is it possible to redefine the basic 16 ansi colors that this patch will use? (perhaps in ~/.Xresources?) I have custom *colorN: ... definitions in my .Xresources file (for urxvt), and I hoped this patch would take them up :-(

Please, fix this bug

@gsf, have you made any progress on getting it updated for 6.1 / does anyone know of a working 6.1 copy?

Whenever I try to build with this on 6.1, I get

error: patch failed: dwm.c:54
error: dwm.c: patch does not apply

@pickfire

Well it seems like it isn't updated to 6.1, @HalosGhost you could just fix that manually.

@ninedotnine

it seems that fixing this patch for dwm 6.1 nontrivial.

the dc ("draw context") struct that this patch depends on has been renamed (to "drw"), moved into a separate file (drw.h), and had various things added or removed.

that's as deep as i was willing to go into the code, at least for now.

will this wonderful patch not be updated to the latest dwm versions? I would really like to use this.
