Enable .twig file extensions

[rubas]

Motivation

• The Liquid template engine shares the basic with the TWIG templating.

• There is no working code formatter out there for TWIG. The only alternative is the melody project from Trivago, but it is outdated, not maintained - and full of known bugs.

---

• Would you consider enabling the .twig extension for the library per default?

We have been successfully using a simple fork of the v0.4 with enabled .twig extension in production since last fall for about a dozen projects. 👍

I do understand that it is not the scope of this project to support TWIG and there will never be an official support. But enabling the plugin for TWIG per default would be extremely valuable for those using it.

Thanks for the consideration.

Thing is there's a lot of things that won't work. Elements that take children require to be flagged as such in the parser, autoescape from the example provided would format as a tag without children, so child tags would appear as sibblings by indentation.

You're free to use it, but I'd use a filetype override in your configuration instead of changing the extension.

You can add this in your settings.json to do that:

  "files.associations": {
    "*.twig": "liquid"
  },
