All files being opened with Ruby syntax instead of Rails

[xeron]

Atom: 0.208.0
OSX: 10.10.3

I've tried controllers, models, helpers and migrations. Always Ruby. Same issue with atom --safe.

Sometimes it works as expected, sometimes it doesn't. Looks like some sort of race condition here?

Yes, there's a race condition since both the HTML (Rails) and HTML (Ruby - ERB) grammars match files ending in .html.erb. Related: #3 and atom/atom#2734

There has been a package to work around this by allowing you to match file types to grammars (file-types), but it broke some time ago. Working off the workaround at execjosh/atom-file-types#17, I've put the following in my init.coffee that fixed the issue:

atom.workspace.observeTextEditors (editor) ->
  path = editor.getPath()
  return unless path?

  fileTypes =
    '.html.erb': 'text.html.ruby'

  for extension of fileTypes when \
      path.toLowerCase().endsWith(extension.toLowerCase()) and
      (longestExtension ? "").length < extension.length
    longestExtension = extension

  return unless longestExtension?
  g = atom.grammars.grammarForScopeName fileTypes[longestExtension]
  return unless g?
  editor.setGrammar g

By adding to the fileTypes object, you can do more workaround for other file types.

In my case this also affect models, controllers, helpers and migrations. Reopening of projects helps sometimes (even w/o restart of Atom). But this is always random. And while project is opened it's always persistent, so all files being opened with Ruby or with Rails syntax, but never mix of both.

Steps to reproduce are like that:

1. Open a project
2. Open any model/controller/helper/migration
3. If syntax is Rails then close a project and repeat from step 1
4. You'll get Ruby syntax after several tries

[jazzpi]

Oh, yes, now I'm noticing that. You can just add '.rb': 'source.ruby.rails' to the fileTypes from my workaround to fix that too.

May be related to atom/first-mate#17

[alepore]

a config like this should work on atom 1.0.8+:

"*":
  core:
    customFileTypes:
      "text.html.ruby": [
        "erb"
      ]

I'm experiencing this with Atom 1.12.2: controller files are being recognized as Ruby rather than Rails files.

I encounter the same problem as @jamieorc on MacOS

[srabuini]

Same here with Atom MacOS 1.19.2 (I think that it never worked properly since the beta versions, though). I recently discovered that disabling the language-ruby package and enabling it again, it starts working properly.

Still encountering this issue.

Atom: 1.32
Mac OS: 10.14
only had encountered issue with this particular version recently, and have to work around with what @alepore proposed @mcelicalderon proposed below 👇 which is editting config.cson

"*":
  core:
    customFileTypes:
      "source.ruby.rails": [
        "rb"
      ]

[mcelicalderon]

This is what fixed it for me, slightly different to @alepore 's solution. On your ~/.atom./config.cson file, add:

"*":
  core:
    customFileTypes:
      "source.ruby.rails": [
        "rb"
      ]

This is what fixed it for me, slightly different to @alepore 's solution. On your ~/.atom./config.cson file, add:

"*":
  core:
    customFileTypes:
      "source.ruby.rails": [
        "rb"
      ]

This solution is a temp fix. For example it will not handle syntax highlight in Gemfile for rails
But works fine for *.rb files
