In GEdit, there is fairly good built-in support for SQL keyword highlighting and such, but it only recognizes the /* */ form of comments. When creating scripts for Oracle, which can also use a pair of dashes (-- ) at the beginning of a line as a single line comment, GEdit highlights key words in such single line comments, which is slightly distracting.

I've looked under root, and also under Home/.config/gedit, and can't locate any place where the language definitions are located so I can add single line comment recognition to GEdit. Does anyone know how I might go about doing this?

I'm using Ubuntu 14.04 by the way.

Thanks.

Gedit uses gtksourceview to define syntax highlighting for several languages. The files are xml and are located in /usr/share/gtksourceview-3.0/language-specs/.

Since you mentioned SQL, the file would be /usr/share/gtksourceview-3.0/language-specs/sql.lang.

Copy that file to ~/.local/share/gtksourceview-3.0/language-specs/sql.lang, then edit to get the highlighting you want.

You can find a tutorial and a reference document here.

Wow - I never would have stumbled on that location unaided. Thanks very very much. I was only able to take a quick peek, but I'm sure that's where I'll be able to do what I need.
