How It Works

peasy-convert is the unified entry point for the Peasy CLI ecosystem. It uses Typer to mount sub-commands from each installed package at runtime:

peasy <suite> <command> [options]
  |       |        |
  |       |        +-- Specific operation (merge, resize, case, gradient, ...)
  |       +----------- Tool suite (pdf, image, text, css, compress, document, audio, video)
  +------------------- Single CLI entry point

Each tool suite is a standalone PyPI package with its own engine and CLI. When you install an extra like peasy-convert[pdf], it pulls in peasy-pdf which registers its commands under peasy pdf. If a suite is not installed, its subcommand simply does not appear -- no errors, no bloat.

# Under the hood — peasy-convert/cli.py
def _register_pdf() -> None:
    try:
        from peasy_pdf.cli import app as pdf_app
        app.add_typer(pdf_app, name="pdf", help="PDF tools")
    except ImportError:
        pass  # Not installed — skip silently

This architecture means you only install the dependencies you need. peasy-convert[text] pulls in zero heavy dependencies. peasy-convert[pdf] adds only pypdf. peasy-convert[image] adds Pillow. Pick what you need.
