Emacs Tree-sitter Syntax Highlighting: Semantic Code Coloring
2025-03-01
This blog post details an enhancement to Emacs's Tree-sitter syntax highlighting, moving beyond basic keyword coloring. The author demonstrates how to leverage Tree-sitter mode to achieve semantic-based highlighting of variable names, differentiating control flow keywords, type aliases, and import statements. By customizing the `treesit-font-lock-rules` function and utilizing the `treesit-inspect-mode` tool, precise control over highlighting rules is achieved, resulting in more intelligent and expressive code coloration. A follow-up post will explore heuristic highlighting based on commonly used variable names.
