🐉 hydra-yaml-lsp

hydra-yaml-lsp is a Language Server Protocol implementation for Hydra YAML configuration files, providing rich language features like code completion, syntax validation, and semantic highlighting to enhance the development experience with Hydra configuration files.

✨ Features

• 💡 Intelligent code completion for Hydra special keys (_target_, _args_, etc.)
• 🔍 Path completion for Python import paths in _target_ values
• 🛠️ Argument completion for callable targets
• 🎨 Semantic token highlighting for special keys, target values, and interpolations
• ⚠️ YAML syntax validation and diagnostics
• 🔄 Support for Hydra interpolations (${...} syntax)
• 🔌 Easy integration with editor extensions (primary integration with VS Code)

📦 Installation

# Install with pip
pip install hydra-yaml-lsp

# For development setup
git clone https://github.com/your-repo/python-hydra-yaml.git
cd python-hydra-yaml/hydra-yaml-lsp
make venv  # Sets up virtual environment with all dependencies

🧰 Requirements

• Python 3.12+

📝 Usage

Standalone Server

python -m hydra_yaml_lsp

Using with VS Code Extension

The primary use case is through the VS Code extension:

1. Install the python-hydra-yaml extension in VS Code
2. Configure the extension to point to your Hydra configuration directory
3. Open any YAML file in that directory to activate the language features

🔧 Development

# Clone and setup development environment
git clone https://github.com/your-repo/python-hydra-yaml.git
cd python-hydra-yaml/hydra-yaml-lsp

# Install dependencies and set up virtual environment
make venv

# Run all tests
make test

# Run type checking
make type

# Run all checks (tests and type checking)
make run
