Match file content for vim syntax highlighting

[reinerh]

Currently the provided syntax files for vim only detect profiles in /etc/firejail/ and ~/.config/firejail/ (based on file extension).
For profile development it might be useful to let vim also detect the filetype in firejail.git/etc/profile-*/.

To accomplish this, you can add the following line to your ~/.vimrc:

autocmd BufRead,BufNewFile * if getline(1) =~ '^# Firejail profile ' | setfiletype firejail | endif

(it will check the first line for # Firejail profile)

I haven't added it to ftdetect/firejail.vim, as I think it's not necessary to scan this for every file opened in vim.
But it might be interesting for people who develop profiles (@glitsj16 @rusty-snake 😄).

Thanks. Until now I allways :set syntax=firejail if I needed highlighting.

An other way is to add

autocmd BufNewFile,BufRead */firejail/*.inc setfiletype firejail
autocmd BufNewFile,BufRead */firejail/*.local setfiletype firejail
autocmd BufNewFile,BufRead */firejail/*.profile setfiletype firejail

to ~/.vimrc (based on https://gitlab.com/kmk3/dotfiles/-/blob/26e0ad5f95f2263e5cef8d1a2e7eca0f4c87bae5/src/.vimrc#L120-124).

autocmd BufNewFile,BufRead */firejail/*.local set syntax=sh
autocmd BufNewFile,BufRead */firejail/*.profile set syntax=sh
