# pkl Plugin
Apple's configuration language with rich validation, IDE support, and multi-format output. Define configs as typed Pkl modules and render them to JSON, YAML, properties, or other formats for apps and tooling.
## Installation
```bash
brew install pkl
# or download from https://github.com/apple/pkl/releases
```
## Basic Usage
```bash
# Evaluate a Pkl module and print JSON to stdout
pkl eval config.pkl
# Write output to a file
pkl eval -o config.json config.pkl
# Format a Pkl file in place
pkl format config.pkl
# Run the Pkl REPL
pkl repl
```
## Common Patterns
```bash
# Evaluate with a specific output format
pkl eval -f yaml config.pkl
# Amend an existing JSON file using a Pkl amend module
pkl eval -m amend config.pkl
# Analyze module dependencies
pkl project resolve
# Check syntax without evaluating
pkl eval --no-cache --trace config.pkl
```
## Usage Examples
- "Convert this Pkl config to JSON for my app"
- "Validate and format my deployment config.pkl"
- "Generate YAML from a typed Pkl module"
## SuperCLI
```bash
sc pkl _ _ eval config.pkl
sc pkl _ _ format config.pkl
sc plugins learn pkl
```
