Half-assed coverage as now just makes for flaky CI.

Let's take it to 100% either by writing the tests or giving up and calling it a # pragma: no cover

I am not a fan of using # pragma: no cover to fake a 100% coverage.

I think we can leave it as it is.

next time someone needs to modify that line, it will be a good opportunity to write a missing test.

We can merge this even if we don't have 100% coverage.

Less than 100% coverage is bad, but for an open source project is nothing to be ashamed of.
Contributors are invited to help complete the coverage by writing missing tests.
So a coverage less than 100% for an open source project means - Help is wanted :)

For a commercial project less than 100% means - Warning, some corners were cut!

I'm confused. The PR is a draft but also a review is requested. And the description talks about "pragma: nocover" but the diff adds no such lines.

This is due to GitHub CODEOWNER automation.

if you create a PR and don't mark it as draft from the start, it will ask for a review.

hynek requested a review from https://github.com/orgs/twisted/teams/twisted-contributors as a code owner 1 hour ago

Here, the PR was first created as "ready" and then was converted to "draft".

Github automation is simple, and the previously requested review was no revoked.

I have honestly never found a way to make a PR a draft right away and then go and look for "make a draft" forever which is tiny text. I wish it were a prominent checkbox somewhere.


As for no covers: I mean cases that can't be realistically or usefully tested. Having 100% coverage is nothing to be proud of (I consider it table stakes and have removed the badge from my projects), it's just a useful state that you've tested everything you want to be tested and don't have to rely on flaky Codecov mathematics.


All that said, it's probably best to do this piece-meal so let's merge this for build.py

The new test looks reasonable (I did not verify that it gets us to 100% coverage, hopefully codecov will wake up and do that). Thank you!

There is an error with the new toml and coverage doesn't work and is not reported as part of the CI.

I wish the CI would fail in this case.

    Error running `['/opt/hostedtoolcache/Python/3.10.6/x64/bin/python', '-m', 'coverage', 'xml', '-i']`: returncode=1, output=b"Can't read 'pyproject.toml' without TOML support. Install with [toml] extra\n"

All good. Thanks. Let's merge. Project coverage can be ignored.

The patch coverage is important.

I wish pip had something like pip install --only-deps

But maybe, we can just do pip install .[dev] and run the tests without tox.

towncrier 22.12.0 (2022-12-21)
==============================

No changes since the previous release candidate.

towncrier 22.12.0rc1 (2022-12-20)
=================================

Features
--------

- Added ``--keep`` option to the ``build`` command that allows generating a newsfile, but keeps the newsfragments in place.
  This option can not be used together with ``--yes``. (`#129 <https://github.com/hawkowl/towncrier/issues/129>`_)
- Python 3.11 is now officially supported. (`#427 <https://github.com/hawkowl/towncrier/issues/427>`_)
- You can now create fragments that are not associated with issues. Start the name of the fragment with ``+`` (e.g. ``+anything.feature``).
  The content of these orphan news fragments will be included in the release notes, at the end of the category corresponding to the file extension.

  To help quickly create a unique orphan news fragment, ``towncrier create +.feature`` will append a random string to the base name of the file, to avoid name collisions. (`#428 <https://github.com/hawkowl/towncrier/issues/428>`_)

Improved Documentation
----------------------

- Improved contribution documentation. (`#415 <https://github.com/hawkowl/towncrier/issues/415>`_)
- Correct a typo in the readme that incorrectly documented custom fragments in a format that does not work. (`#424 <https://github.com/hawkowl/towncrier/issues/424>`_)
- The documentation has been restructured and (hopefully) improved. (`#435 <https://github.com/hawkowl/towncrier/issues/435>`_)
- Added a Markdown-based how-to guide. (`#436 <https://github.com/hawkowl/towncrier/issues/436>`_)
- Defining custom fragments using a TOML array is not deprecated anymore. (`#438 <https://github.com/hawkowl/towncrier/issues/438>`_)

Deprecations and Removals
-------------------------

- Default branch for `towncrier check` is now "origin/main" instead of "origin/master".
  If "origin/main" does not exist, fallback to "origin/master" with a deprecation warning. (`#400 <https://github.com/hawkowl/towncrier/issues/400>`_)

towncrier 22.8.0 (2022-08-29)
=============================

No significant changes since the previous release candidate.

towncrier 22.8.0.rc1 (2022-08-28)
=================================

Features
--------

- Make the check subcommand succeed for branches that change the news file

  This should enable the ``check`` subcommand to be used as a CI lint step and
  not fail when a pull request only modifies the configured news file (i.e. when
  the news file is being assembled for the next release). (`#337 <https://github.com/hawkowl/towncrier/issues/337>`_)
- Added support to tables in toml settings, which provides a more intuitive
  way to configure custom types. (`#369 <https://github.com/hawkowl/towncrier/issues/369>`_)
- The `towncrier create` command line now has a new `-m TEXT` argument that is used to define the content of the newly created fragment. (`#374 <https://github.com/hawkowl/towncrier/issues/374>`_)

Bugfixes
--------

- The extra newline between the title and rendered content when using ``--draft`` is no longer inserted. (`#105 <https://github.com/hawkowl/towncrier/issues/105>`_)
- The detection of duplicate release notes was fixed and recording changes of same version is no longer triggered.

  Support for having the release notes for each version in a separate file is working again. This is a regression introduced in VERSION 19.9.0rc1. (`#391 <https://github.com/hawkowl/towncrier/issues/391>`_)

Improved Documentation
----------------------

- Improve ``CONTRIBUTING.rst`` and add PR template. (`#342 <https://github.com/hawkowl/towncrier/issues/342>`_)
- Move docs too the main branch and document custom fragment types. (`#367 <https://github.com/hawkowl/towncrier/issues/367>`_)
- The CLI help messages were updated to contain more information. (`#384 <https://github.com/hawkowl/towncrier/issues/384>`_)

Deprecations and Removals
-------------------------

- Support for all Python versions older than 3.7 has been dropped. (`#378 <https://github.com/hawkowl/towncrier/issues/378>`_)

towncrier 21.9.0 (2022-02-04)
=============================

Features
--------

- towncrier --version` was added to the command line interface to show the product version. (`#339 <https://github.com/hawkowl/towncrier/issues/339>`_)
- Support Toml v1 syntax with tomli on Python 3.6+ (`#354 <https://github.com/hawkowl/towncrier/issues/354>`_)

Bugfixes
--------

- Stop writing title twice when ``title_format`` is specified. (`#346 <https://github.com/hawkowl/towncrier/issues/346>`_)
- Disable universal newlines when reading TOML (`#359 <https://github.com/hawkowl/towncrier/issues/359>`_)

towncrier 21.3.0 (2021-04-02)
=============================

No significant changes since the previous release candidate.

towncrier 21.3.0.rc1 (2021-03-21)
=================================

Features
--------

- Ticket number from file names will be stripped down to avoid ticket links such as ``#7``. (`#126 <https://github.com/hawkowl/towncrier/issues/126>`_)
- Allow definition of the project ``version`` and ``name`` in the configuration file.
  This allows use of towncrier seamlessly with non-Python projects. (`#165 <https://github.com/hawkowl/towncrier/issues/165>`_)
- Improve news fragment file name parsing to allow using file names like
  ``123.feature.1.ext`` which are convenient when one wants to use an appropriate
  extension (e.g. ``rst``, ``md``) to enable syntax highlighting. (`#173 <https://github.com/hawkowl/towncrier/issues/173>`_)
- The new ``--edit`` option of the ``create`` subcommand launches an editor for entering the contents of the newsfragment. (`#275 <https://github.com/hawkowl/towncrier/issues/275>`_)
- CPython 3.8 and 3.9 are now part of our automated test matrix and are officially supported. (`#291 <https://github.com/hawkowl/towncrier/issues/291>`_)
- When searching for the project, first check for an existing importable instance.
  This helps if the version is only available in the installed version and not the source. (`#297 <https://github.com/hawkowl/towncrier/issues/297>`_)
- Support building with PEP 517. (`#314 <https://github.com/hawkowl/towncrier/issues/314>`_)

Bugfixes
--------

- Configuration errors found during command line execution now trigger a message to stderr and no longer show a traceback. (`#84 <https://github.com/hawkowl/towncrier/issues/84>`_)
- A configuration error is triggered when the newsfragment files couldn't be discovered. (`#85 <https://github.com/hawkowl/towncrier/issues/85>`_)
- Invoking towncrier as `python -m towncrier` works. (`#163 <https://github.com/hawkowl/towncrier/issues/163>`_)
- ``check`` subcommand defaults to UTF-8 encoding when ``sys.stdout.encoding`` is ``None``.
  This happens, for example, with Python 2 on GitHub Actions or when the output is piped. (`#175 <https://github.com/hawkowl/towncrier/issues/175>`_)
- Specifying ``title_format`` disables default top line creation to avoid duplication. (`#180 <https://github.com/hawkowl/towncrier/issues/180>`_)

Improved Documentation
----------------------

- The README now mentions the possibility to name the configuration file
  ``towncrier.toml`` (in addition to ``pyproject.toml``). (`#172 <https://github.com/hawkowl/towncrier/issues/172>`_)
- ``start_line`` corrected to ``start_string`` in the readme to match the long standing implementation. (`#277 <https://github.com/hawkowl/towncrier/issues/277>`_)

towncrier 19.9.0 (2021-03-20)
=============================

No significant changes.

towncrier 19.9.0rc1 (2019-09-16)
================================

Features
--------

- Add ``create`` subcommand, which can be used to quickly create a news
  fragment command in the location defined by config. (`#4 <https://github.com/hawkowl/towncrier/issues/4>`_)
- Add support for subcommands, meaning the functionality of the ``towncrier``
  executable is now replaced by the ``build`` subcommand::

      $ towncrier build --draft

  A new ``check`` subcommand is exposed. This is an alternative to calling the
  ``towncrier.check`` module manually::

      $ towncrier check

  Calling ``towncrier`` without a subcommand will result in a call to the
  ``build`` subcommand to ensure backwards compatibility. This may be removed in a
  future release. (`#144 <https://github.com/hawkowl/towncrier/issues/144>`_)
- Towncrier's templating now allows configuration of the version header. *CUSTOM TEMPLATE USERS PLEASE NOTE: You will need to add the version header information to your template!* (`#147 <https://github.com/hawkowl/towncrier/issues/147>`_)
- towncrier now accepts the --config argument to specify a custom configuration file (`#157 <https://github.com/hawkowl/towncrier/issues/157>`_)
- There is now the option for ``all_bullets = false`` in the configuration.
  Setting ``all_bullets`` to false means that news fragments have to include
  the bullet point if they should be rendered as enumerations, otherwise
  they are rendered directly (this means fragments can include a header.).
  It is necessary to set this option to avoid (incorrect) automatic indentation
  of multiline fragments that do not include bullet points.
  The ``single-file-no-bullets.rst`` template gives an example of
  using these options. (`#158 <https://github.com/hawkowl/towncrier/issues/158>`_)
- The ``single_file`` option can now be added to the configuration file. When set to ``true``, the filename key can now be formattable with the ``name``, ``version``, and ``project_date`` format variables. This allows subsequent versions to be written out to new files instead of appended to an existing one. (`#161 <https://github.com/hawkowl/towncrier/issues/161>`_)
- You can now specify Towncrier-bundled templates in your configuration file. Available templates are `default`, `hr-between-versions` (as used in attrs), and `single-file-no-bullets`. (`#162 <https://github.com/hawkowl/towncrier/issues/162>`_)

Bugfixes
--------

- Accept newsfragment filenames with multiple dots, like `fix-1.2.3.bugfix`. (`#142 <https://github.com/hawkowl/towncrier/issues/142>`_)

Deprecations and Removals
-------------------------

- The `--pyproject` option for `towncrier check` is now replaced with `--config`, for consistency with other commands. (`#162 <https://github.com/hawkowl/towncrier/issues/162>`_)
