Possible to use backrefs in ansible_template_syntaxes? #88

Closed stove-panini closed 4 years ago

The jinja2 syntax highlighting doesn't automatically pick up on the root filetype. I tried to use backrefs to help with this, but it doesn't seem to work.

let g:ansible_template_syntaxes = { '\(.*\)\.\(.*\)\.j2': '\2' }

I know with vim, you need to escape the parentheses for capturing groups, but I tried 'em unescaped, too. Here's the breakdown:

\(.*\) - Capture Group 1, the filename \. - A literal dot \(.*\) - Capture Group 2, the root filetype \.j2 - The j2 filetype

The value of the setting should be \2, whatever was in Capture Group 2.

The loop for this is pretty naive, meant mostly for basic patterns and quick setups.

It's probably best to just have a workaround for this in your vimrc - and set the filetype manually.
