Custom Editor Themes

---

Keyman Developer embeds the Monaco open source text editor. The highlighting and styles for the text editor are customisable with a JSON file configured in the Options dialog. The JSON file must be a valid Monaco theme (passed as second parameter to monaco.editor.defineTheme).

Example

{
  "base": "vs-dark",
  "inherit": true,
  "rules": [
    { "token": "comment", "foreground": "ffa500", "background": "303030", "fontStyle": "italic underline" },
    { "token": "comment.js", "foreground": "008800", "fontStyle": "bold" },
    { "token": "comment.css", "foreground": "0000ff", "fontStyle": "bold", "inherit": false, "background": "808080" }
  ]
}
