Description Yu Yuwei 2010-11-24 14:04:22 UTC
I shifted from vim recently, and wish app-emacs/gentoo-syntax can provide better syntax-highlight for the USE flags in /etc/make.conf.

For example:
USE="emacs -vim"
The "emacs" in blue color and "-vim" in red color, or some other colors.


Reproducible: Always

I haven't found time for this yet, and most probably won't in the next future.

Patches are welcome.

Emacs doesn't use ebuild-mode for make.conf, but conf-unix-mode. For the requested highlighting, one would have to add "USE=" and the flag syntax to the font-lock keywords of that mode (or a mode derived from it), most likely something of the form "(matcher . anchored-highlighter)". See the Elisp Reference Manual:

A complication is that a variable assignment in make.conf can span multiple lines, therefore the standard line-based approach won't work. A possible solution to this is outlined here:

Also, comment #1 still applies.
