Bug#1019257: vim: syntax highlight: roff, man: man highlighting could be

From: Alejandro Colomar
Subject: Bug#1019257: vim: syntax highlight: roff, man: man highlighting could be improved with some roff rules
Date: Tue, 06 Sep 2022 13:39:55 +0200

Package: vim
Version: 2:9.0.0242-1
Severity: wishlist
Tags: upstream


man(7) pages with a filename as are interpreted by vim as
written in man(7).  However, if the filename is written as foo.7,
vim thinks they are written in roff(7).  That's not a big issue,
but it's not really correct: although manual pages written in pure
roff(7) will work with man(1), it's very rare to find such pages
in the wild.  Vim could be fixed to realize that .[0-9] files are
man(7) pages, and highlight them as such.

I realized that vim didn't consider those as true man(7) pages
when I wrote some pages with the *.man extension for some tests.
The highlighting is different, and in some ways inferior.

Vim highlights macros, embedded tbl(1), and comments, within the
manual pages when it thinks they are written in roff(7).  But when
it thinks they are written in man(7), it doesn't highlight any of
those things, and it's a bit more difficult to read.
