How it works

Chau7 includes a built-in text editor with syntax highlighting for over 50 programming and configuration languages. Open any file and the editor detects the language from the file extension or shebang line and applies appropriate syntax coloring. Supported languages include Python, JavaScript, TypeScript, Rust, Go, Swift, Ruby, YAML, TOML, JSON, Markdown, Shell scripts, Dockerfiles, and many more.

The syntax engine uses Tree-sitter grammars for accurate, incremental parsing. This means highlighting stays correct even in complex nested structures and updates efficiently as you type rather than re-parsing the entire file. Theme colors from your terminal theme are applied to syntax tokens, so highlighting integrates visually with your chosen color scheme.

The editor is designed to be immediately usable without memorizing keybindings. Standard macOS shortcuts (Cmd+S to save, Cmd+Z to undo, Cmd+F to find) work as expected. For developers comfortable with modal editing, Vim keybindings are available as an option. The goal is a quick-edit experience that removes the barrier of learning Vim or Emacs for simple file edits.

Why it matters

Terminal text editors sit at two extremes: Vim (powerful, steep learning curve) and nano (simple, no syntax highlighting). Chau7's built-in editor provides syntax highlighting for common languages with zero learning curve. Open a file, see colors, edit, save. That's it.

Frequently asked questions

What languages are supported for syntax highlighting?

Over 50 languages including Python, JavaScript, TypeScript, Rust, Go, Swift, Ruby, C, C++, Java, YAML, TOML, JSON, Markdown, Shell, Dockerfile, and more. Language detection is automatic from file extension or shebang.

Do I need to learn Vim keybindings to use the editor?

No. The editor uses standard macOS keyboard shortcuts by default. Vim keybindings are available as an optional preset for developers who prefer modal editing.

Does the editor use my terminal theme colors?

Yes. Syntax highlighting tokens are colored using your current terminal theme, so the editor integrates visually with the rest of your terminal.
