[SOLVED] How to change the per-language configuration of setting "editor.insertSpaces" to "auto"

How to change the per-language configuration of setting "editor.insertSpaces" to "auto"

I'm using VS Code to edit projects in multiple languages (mostly Ruby, PHP and Javascript) and for each language we have different indentation models (spaces/tabs and width). Looks like VS Code supports this as it allows both editor.insertSpaces and editor.tabSize to be set to "auto" which is a per-language definition.

But while editor.tabSize looks to do about what I want, editor.insertSpaces always insert spaces when in "auto" mode.

I've tried to find where one can edit the per-language configuration but have found no such setting. I've also looked in the language directories under resources/app/client/vs/languages but have failed to find something that specifies these features.

Any idea how to customize the per-language settings?

Solution

To use perlanguage settings, you use the [language_id] in square brackets:

example:

{
  "[typescript]": {
    "editor.formatOnSave": true,
    "editor.formatOnPaste": true
  },
  "[markdown]": {
    "editor.formatOnSave": true,
    "editor.wrappingColumn": 0,
    "editor.renderWhitespace": "all",
    "editor.acceptSuggestionOnEnter": false
  }
}

Update: editor.tabSize and editor.insertSpaces are now supported in version 1.10
