Code R6 Class

Displays source code with syntax highlighting. Each line is a Text submobject. Tokens are colored according to a theme (default: monokai). Includes an optional background rectangle and line numbers.

Details

Syntax highlighting uses simple regex-based token classification. For R, Python, and JavaScript, common patterns (keywords, strings, comments, numbers) are recognized and colored.
