# packaging-repositories: pip package finder extraction prototype.

Discussion: https://github.com/pypa/pip/issues/5800

Proposed API:

```python

from packaging_repositories import (

    Fetcher, VersionFilter,

    SimpleRepository, FlatHTMLRepository, LocalDirectoryRepository,

)

class RequestsFetcher(Fetcher):

    """Fetch implementation using requests to perform remote requests.

    """

class AIOHTTPFetcher(Fetcher):

    """Fetch implementation using AIOHTTP to perform remote requests.

    """

# This does not check if the endpoint is actually available (done lazily when

# the repos is actually accessed), but LocalDirectoryRepository does check

# whether the path/URL is actually local. FlatHTMLRepository automatically

# converts file: URLs to paths, so the fetcher implementation does not need

# to worry about special-casing them.

repos = [

    SimpleRepository('https://pypi.org/simple'),

    FlatHTMLRepository('https://pypackages.mydomain.com/find-links.html'),

    FlatHTMLRepository('/path/to/find-links.html'),

    LocalDirectoryRepository('/path/to/local/directory'),

]

version_filter = VersionFilter('>=10,<18')

for repo in repos:

    fetcher = RequestsFetcher(repo, 'pip')

    for entry in version_filter(fetcher):

        print(entry)

    # Maybe it is a good idea to separate base classes for fetchers?

    # SynchronousFetcher implements ``__next__``, and AsynchronousFetcher

    # implements ``__anext__``.

    fetcher = AIOHTTPFetcher(repo, 'pip')

    async for entry in version_filter(fetcher):

        print(entry)

```
