Customizing Themes

In case you are interested in tweaking the theme and style for IDL syntax, here are the token names associated with IDL's TextMate grammar file.

Using the name of tokens, you can update VSCode's preferences to manually change the appearance/style of the tokens.

In your JSON settings file, this would look something like:

"editor.tokenColorCustomizations": {
  "textMateRules": [{
    "scope": "keyword.operator.idl",
    "settings": {
      "foreground": "#FF0000",
      "fontStyle": "bold"
    }
  }]
}

Below is a list which shows, on the right hand side, the token names used for IDL.

You can also find this information directly within the editor by using the "Developer: Inspect Editor Tokens and Scopes" command. (Quick access using Ctrl + Shift + P on Windows to open the command palette).

If this is not 100% up-to-date, then let us know.
