Creating your own syntax highlighting in GEdit?

Question

How do you add a 'keyword' to the GEdit list of keywords? I basiclly want to make the printf function look like a keyword.

printf("Hello World\n");

GEdit uses GtkSourceView for its syntax highlighting. You should be able to find the c.lang file it uses to highlight C code by typing a command like this:

$ locate gtksourceview | grep /c.lang

Once you find the lang file, open it up in a text editor (it's an XML file) and near the bottom you'll see a list of keywords which you should be able to add printf to.

do you know if this file is also named c.lang in gedit for mac? It should be, but when I searched for this file in finder nothing was found... – Evaleen

I made a copy of c.lang and renamed it into proglang.lang, changed <language id="c" _name="C" version="2.0" _section="Sources"> into <language id="proglang" _name="ProgLang" version="2.0" _section="Sources">. While it shows up in the menu, it won't highlight anything. Why is that? Is there some registry like thing needed to be done here? – Sulfapyridine

Thanks to Jeremy's post I found this page: Projects/GtkSourceView - GNOME Wiki! or GtkSourceView - Documentation (from Wayback Machine)

Here you'll find a link to both a tutorial and the official reference for the language definition files.
