When editing a Perl file, gedit 2.30.3 highlights FIXME, TODO and XXX when they appear in a comment. Where is this documented? How can this be modified?

  • From Ether's link, `grep FIXME $(locate gtksourceview | grep /perl.lang)`, I found nothing defining the handling of FIXME. – CW Holeman II Jan 26 '11 at 23:05

It's documented here: http://library.gnome.org/devel/gtksourceview/stable/lang-tutorial.html Do a search for "in-comment".

You can do modifications in the def.lang file located in /usr/share/gtksourceview-2.0/language-specs if you're on Ubuntu.

Run a search for "comment-note" and you'll see where the regex is declared.

    `def.lang` rather than `perl.lang` defines these values within a comment to get special highlighting: "FIXME|TODO|XXX". – CW Holeman II Feb 04 '11 at 05:48
