pyGTK a syntax parser


Zdravim,
pokousim se napsat jednoduchou syntaxi pro muj osobni editurek.
Vstup bude jako slovnik. Jen keyword a jeho syntaxe. Nic vic.
Zatim to skoro funguje az na par malickosti ktere poznate ze zdrojaku.
Pr: slovo Program mi obarvi dobre s Programy uz ma problemy :)
Neporadi nekdo ?
BTW : gtksourcebuffer a pygtkcodbuffer nechci pouzit.

# Tag Buffer
# Pokus o napsani vlastniho jednoducheho syntax parseru
# vstup: data v podobe slovniku
#        key je Keyword a value je typ tagu pouzity
#        pro syntaxi
# com dot tbs-software at spooky.ln [ reverse it !!! ]
