### Tree-sitter Integration (Better Syntax Highlighting)
Tree-sitter is an incremental parsing system introduced in Emacs 29 that provides precise, high-performance syntax analysis and highlighting by constructing concrete syntax trees from source code. It supports a broad set of programming languages, including Bash, C, C++, C#, CMake, CSS, Dockerfile, Go, Java, JavaScript, JSON, Python, Rust, TOML, TypeScript, YAML, Elisp, Lua, Markdown, and many others. Unlike traditional font-lock, which relies on regular expressions, Tree-sitter uses formal grammar definitions to build real-time parse trees, enabling accurate syntax highlighting, structural navigation, code folding, and foundational support for advanced editing features like refactoring.
The configuration below enables Tree-sitter support using the [treesit-auto](https://github.com/renzmann/treesit-auto) package. Setting `treesit-auto-add-to-auto-mode-alist` to `'all` ensures that all available Tree-sitter modes are automatically activated for their corresponding file types. Enabling `global-treesit-auto-mode` applies this behavior globally, improving syntax accuracy and consistency across supported languages.
To enable Tree-sitter, add the following to your `~/.emacs.d/post-init.el`:
