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"); 

Answer 1

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.

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.
