emmylua_doc_cli is a powerful command-line tool for generating documentation directly from your Lua source code and EmmyLua annotations. Built with Rust, it offers exceptional performance and is a core component of the emmylua-analyzer-rust ecosystem.

✨ Features

• 🚀 Blazing Fast: Leverages Rust's performance to parse and generate documentation for large codebases in seconds.
• ✍️ Rich Annotation Support: Intelligently interprets EmmyLua annotations (---@class, ---@field, ---@param, etc.) to generate detailed and accurate documentation.
• 🔧 Highly Customizable:
  • Override the default templates with --override-template to match your project's branding.
  • Inject custom content into the main page using the --mixin option to add guides, tutorials, or other static pages.
• 📦 Multiple Output Formats: Generate documentation in Markdown or JSON for maximum flexibility.
• 🤝 CI/CD Ready: Automate your documentation publishing workflow with seamless integration into services like GitHub Actions.

📦 Installation

Install emmylua_doc_cli via cargo:

cargo install emmylua_doc_cli

Alternatively, you can grab pre-built binaries from the GitHub Releases page.

🚀 Usage

Basic Usage

Generate documentation for all Lua files in the src directory and output to the default ./docs folder:

emmylua_doc_cli ./src -o ./docs

Advanced Usage

Generate JSON Output

Output the documentation structure as a JSON file for custom processing:

emmylua_doc_cli . -f json -o ./api.json

Customize Site Name

Set a custom name for the generated documentation site:

emmylua_doc_cli . -o ./docs --site-name "My Awesome Project"

Ignore Files

Exclude certain directories or files from the documentation:

emmylua_doc_cli . -o ./docs --ignore "third_party/**,test/**"

🛠️ CI/CD Integration

Automate the process of building and deploying your documentation to GitHub Pages using GitHub Actions.
