Theme Schema

This page documents the theme keys currently parsed by rememberEditorTheme().

How Theme Parsing Works

rememberEditorTheme() starts from a built-in dark or light fallback theme
themeContent is parsed in the Compose layer
matching keys override fallback values
font settings are merged from EditorFontConfig
textStyles can be extended through named style aliases

The following top-level color keys are supported:

backgroundColor
textColor
cursorColor
selectionColor
lineNumberColor
currentLineNumberColor
currentLineColor
guideColor
separatorLineColor
splitLineColor

Minimal Example

json

{
  "backgroundColor": "#1B1E24",
  "textColor": "#D7DEE9",
  "cursorColor": "#8FB8FF",
  "phantomTextColor": "#8AA3B5D1",
  "textStyles": {
    "keyword": {
      "color": "#7AA2F7",
      "fontStyle": "bold"
    },
    "comment": {
      "color": "#7A8294",
      "fontStyle": "italic"
    }
  }
}

Value Format

Color values can be written as:

#RRGGBB
#AARRGGBB
signed integer values

Font Style Notes

Inside textStyles, supported font style flags are mapped by parser logic. Typical values are:

bold
italic

What Is Not Theme Schema

Theme content does not replace runtime behavior settings such as:

wrap mode
read-only mode
gutter sticky behavior
current line render mode

Use EditorSettings for those.
