Configuring the Source Editor#

The Source Editor is used to edit the raw content of text-based files. Client Sharing users and editor-level team members do not have access to it.

Syntax highlighting is automatically detected from the extension of the file you are opening.


To change the appearance and behavior of the Source Editor, use the source_editor option in your global configuration:

  tab_size: 2
  show_gutter: false
  theme: dawn
  "source_editor": {
    "tab_size": 2,
    "show_gutter": false,
    "theme": "dawn"
module.exports = {
  source_editor: {
    tab_size: 2,
    show_gutter: false,
    theme: "dawn"
