Allow yml files to be named yml.erb

[iHiD]

It would be nice if I could name the skylight.yml to be skylight.yml.erb. I currently get yaml parse errors when committing my version of that file, as it contains multiline ERB, which Ruby parses fine, but Prettier baulks at. Being able to append the erb extension would fix this.

This may already be the case, in which case please feel free to close this (although it might be worth making it clearer in the docs as I missed it, or equally feel free to tell me I'm just not looking hard enough!)

Thanks 🙂

Hi @iHiD! I just tried out Prettier on a skylight.yml.erb file, and it seems not to correctly infer a parser for .erb files (it tried using the Ruby parser). Is there a particular plugin you are using for ERB support? If so, you can add an override to your .prettierrc.json file:

    {
      "files": ["config/skylight.yml"],
      "options": {
        "parser": "erb"
      }
    }

If not, it might be best to add it to .prettierignore.

Thanks for the answer :)

I don't actually particularly mind about it prettifying the ERB, the real issue was that it totally exploded trying to parse the YAML file when it contained multiline erb. So by naming it to yml.erb it won't try and prettify it as yaml and break.

But yes, .prettierignore is the good local fix :)
