Command Line Tool
-----------------

[](#command-line-tool)

[![CLI Demo](docs/demo_cli.png)](docs/demo_cli.png)

Features
--------

[](#features)

- **ANSI Renderer**: Uses half-block characters (`▀`, `▄`, `█`) and ANSI colors to render high-resolution QR codes in the terminal.
- **ASCII Renderer**: Fallback renderer using full block characters (`██`) and spaces for broader compatibility.
- **Auto-detection**: Automatically selects the best renderer based on terminal capabilities (TTY, `NO_COLOR`, `TERM`).
- **Zero Dependencies**: Only requires `bacon/bacon-qr-code` for matrix generation.
- **Static Analysis**: Strict type checking with PHPStan (max level).
- **Coding Standard**: Adheres to `brzuchal/coding-standard`.
