Syntax Highlightining in Python

Working on Rapache, it’s been a while I wanted to add syntax highlightining, but I didn’t dare too loose time on a “side feature” like that. Last night though, Jason came in chat, and pasted me the code to do that straight away. That was nice, I only needed to paste that code in the source and make little adjustments.

Some little glitches arose though, so I eventually had to work a little more on it. I just thought I’d share what I had to do with other people.

My problems:

• I had to put together a language definition for Apache config files, since no one currently exists
• I had to find out how to read if from a non system dir (ie. from my program data directory)

This is the Apache .lang file (needs more love, but that’s a start) ended up with.

Here’s the code:

import gtksourceview2
custom_langs_path = '/home/myuser/mydir/datafiles'
bufferS = gtksourceview2.Buffer()
manager = gtksourceview2.LanguageManager()
manager.set_search_path( [ custom_langs_path ] + manager.get_search_path() )
language = manager.get_language('apache')
bufferS.set_language(language)
bufferS.set_highlight_syntax(True)
sourceview = gtksourceview2.View(bufferS)
sourceview.set_show_line_numbers(True)
#TODO sniff gnome default monospace font
sourceview.modify_font(pango.FontDescription("monospace 10"))

This is how the final result looks like:

Everything looks nicer now !

Share it !
