Nano syntax highlighting
From Gentoo Linux Wiki
| This article is not very long. You could help Gentoo-Wiki by editing this article. |
Gentoo installs nano with a decent set of syntax highlighting files. This page contains some that are improvements on the default files, or not included in the pre-existing set.
Note: By default, syntax files in /usr/share/nano are commented out in /etc/nanorc. To enable syntax highlighting, uncomment the lines near the bottom of /etc/nanorc.
