Get started

import anyio.to_thread
import pooch
import pooch_rattler

# Register global default
pooch_rattler.install()

# Synchronous download
downloaded_file = pooch.retrieve("https://example.com/index.html")

# Asynchronous download
async def async_download():
    # We still need a worker thread to look for existing cache,
    # validate checksums and decompress downloaded files
    return await anyio.to_thread.run_sync(
        pooch.retrieve, "https://example.com/index.html")

cached_file = anyio.run(async_download)
assert cached_file == downloaded_file

Downloaders can also be created and invoked explicitly. Examples can be found in the unit tests.
