Enable Vim syntax highlighting regardless of filename extension

Question

I am opening a file with no extension with vim, say:

myappsetting.conf

This file is actually a *.ini file, with following formats:

[setting_a]
yo = 1234

How can I enable vim to correctly display this file with colour with the correct format?

I am looking for some vim command like:

:set syntaxtype=ini

Thanks.

Answer 1

Put this in your .vimrc :

au BufReadPost *.conf set syntax=ini

Answer 2

I was having the same issue on my Arch linux desktop. I found these files owned by the vim-runtime package.

$ pacman -Qlq vim-runtime | grep dosini
/usr/share/vim/vim74/ftplugin/dosini.vim
/usr/share/vim/vim74/syntax/dosini.vim

Based on that, I found I could get dosini highlighting either by setting the syntax (syn) or the filetype (ft).

:set ft=dosini

You can have this happen automatically with a vim modeline. Add this to the last line of your file.

# vim: set ft=dosini :
