Pypi-simple

-------------------
- Removed deprecated functionality:
- `DistributionPackage.get_digests()`
- `PyPISimple.get_projects()`
- `PyPISimple.get_project_files()`
- `parse_simple_index()`
- `parse_project_page()`
- `parse_links()`
- Drop support for Python 3.6
- Support Python 3.11
- `IndexPage`, `ProjectPage`, `DistributionPackage`, and `Link` have been
changed from NamedTuples to dataclasses
- Replaced `DistributionPackage.yanked` with separate `is_yanked` and
`yanked_reason` attributes
- `parse_filename()` now raises an `UnparsableFilenameError` on unparsable
filenames instead of returning a triple of `None`s
- `PyPISimple.get_project_page()` now raises a `NoSuchProjectError` on 404
responses instead of returning `None`
- The functions for parsing data into `IndexPage` and `ProjectPage` instances
have been replaced with classmethods:
- `parse_repo_index_page()` → `IndexPage.from_html()`
- `parse_repo_index_json()` → `IndexPage.from_json_data()`
- `parse_repo_index_response()` → `IndexPage.from_response()`
- `parse_repo_links()` → `RepositoryPage.from_html()`
- `parse_repo_project_page()` → `ProjectPage.from_html()`
- `parse_repo_project_json()` → `ProjectPage.from_json_data()`
- `parse_repo_project_response()` → `ProjectPage.from_response()`
- Add a `RepositoryPage` class for representing the return value of
`parse_repo_links()` (now called `RepositoryPage.from_html()`)
- Renamed `DistributionPackage.from_pep691_details()` to `from_json_data()`
- `PyPISimple.stream_project_names()` now accepts JSON responses
- Use pydantic internally to parse JSON responses
- Added constants for passing to `PyPISimple` and its methods in order to
specify the `Accept` header to send

--------------------
- Support Python 3.10
- Support PEP 691
- Send "Accept" headers in requests (except for `stream_project_names()`)
listing both the new JSON format and the old HTML format
- `parse_repo_project_response()` and `parse_repo_index_response()` now
support both the JSON and HTML formats
- Add `parse_repo_index_json()` and `parse_repo_project_json()` functions
- Gave `DistributionPackage` a `from_pep691_details()` classmethod
- `DistributionPackage.has_metadata` will now be `None` if not specified by
a JSON response
- `DistributionPackage.metadata_url` is now always non-`None`
- Gave `DistributionPackage` a `digests` attribute
- The `get_digests()` method of `DistributionPackage` is now deprecated;
use `digests` instead
- Digest fragments are now removed from `DistributionPackage.url` when
parsing HTML responses
- Warn on encountering a repository version with a greater minor version than
expected
- Gave `PyPISimple` a `download_package()` method

-------------------
- Support PEP 658 by adding `has_metadata`, `metadata_url`, and
`metadata_digests` attributes to `DistributionPackage`

-------------------
- Support Python 3.9
- `PyPISimple` is now usable as a context manager that will close the session
on exit

-------------------
- Drop support for Python 2.7, Python 3.4, and Python 3.5
- `DistributionPackage.has_sig` is now `None` if the package repository does
not report this information
- Added type annotations
- Moved documentation from README file to a Read the Docs site
- Added new methods to `PyPISimple`:
- `get_index_page()` — Returns an `IndexPage` instance with a `projects:
List[str]` attribute plus other attributes for repository metadata
- `get_project_page()` — Returns a `ProjectPage` instance with a `packages:
List[DistributionPackage]` attribute plus other attributes for repository
metadata
- `stream_project_names()` — Retrieves project names from a repository
using a streaming request
- New utility functions:
- `parse_repo_links()` — Parses an HTML page and returns a pair of
repository metadata and a list of `Link` objects
- `parse_repo_project_page()` — Parses a project page and returns a
`ProjectPage` instance
- `parse_repo_project_response()` — Parses a `requests.Response` object
containing a project page and returns a `ProjectPage` instance
- `parse_links_stream()` — Parses an HTML page as stream of `bytes` or
`str` and returns a generator of `Link` objects
- `parse_links_stream_response()` — Parses a streaming `requests.Response`
object containing an HTML page and returns a generator of `Link` objects
- `parse_repo_index_page()` — Parses a simple repository index/root page
and returns an `IndexPage` instance
- `parse_repo_index_response()` — Parses a `requests.Response` object
containing an index page and returns an `IndexPage` instance
- The following functions & methods are now deprecated and will be removed in a
future version:
- `PyPISimple.get_projects()`
- `PyPISimple.get_project_files()`
- `parse_simple_index()`
- `parse_project_page()`
- `parse_links()`
- Support Warehouse's ``X-PyPI-Last-Serial`` header by attaching the value to
the objects returned by `get_index_page()` and `get_project_page()`
- Support PEP 629 by attaching the repository version to the objects returned
by `get_index_page()` and `get_project_page()` and by raising an
`UnsupportedRepoVersionError` when a repository with an unsupported version
is encountered

-------------------
- Support Python 3.8
- `DistributionPackage.sig_url` is now always non-`None`, as Warehouse does not
report proper values for `has_sig`
