Usage
=====
To use Releases, mimic the format seen in `its own changelog
<https://raw.github.com/bitprophet/releases/master/docs/changelog.rst>`_ or in
`Fabric's changelog
<https://raw.github.com/fabric/fabric/master/sites/www/changelog.rst>`_.
Specifically:
* Install ``releases`` and update your Sphinx ``conf.py`` to include it in the
``extensions`` list setting: ``extensions = ['releases']``.
* Also set the ``releases_release_uri`` and ``releases_issue_uri`` top
level options - they determine the targets of the issue & release links
in the HTML output. Both should have an unevaluated ``%s`` where the
release/issue number would go.
* Alternately, if your project is hosted on Github, set the
``releases_github_path`` setting instead, to e.g.
``account/project``. Releases will then use an appropriate Github
URL for both releases and issues.
* If ``releases_release_uri`` or ``releases_issue_uri`` are *also*
configured, they will be preferred over ``releases_github_path``.
(If only one is configured, the other link type will continue using
``releases_github_path``.)
* See `Fabric's docs/conf.py
<https://github.com/fabric/fabric/blob/4afd33e971f1c6831cc33fd3228013f7484fbe35/docs/conf.py#L31>`_
for an example.
* You may optionally set ``releases_debug = True`` to see debug output
while building your docs.
* If your changelog includes "simple" pre-1.0 releases derived from a
single branch (i.e. without stable release lines & semantic versioning)
you may want to set ``releases_unstable_prehistory = True``.
* This is also useful if you've just imported a non-Releases changelog,
where your issues are all basic list-items and you don't want to go
through and add bug/feature/support/etc roles.
* See :ref:`the appropriate conceptual docs <unstable-prehistory>` for
details on this behavior.
* Create a Sphinx document named ``changelog.rst`` containing a bulleted list
somewhere at its topmost level.
* If you wish to use a different document name, use another config option
(as per previous bullet point), ``releases_document_name``. E.g.
``releases_document_name = "CHANGES"`` would cause Releases to mutate a
file called ``CHANGES.rst`` instead of ``changelog.rst``.
* It is possible to have multiple changelogs (useful, for example, if you
are documenting multiple sub-projects). In this case set
``releases_docuement_name`` to a list containing all the changelogs you
want processed. Each changelog must be explicitly listed. E.g.
``releases_document_name = ['project_1/changelog', 'project_2/changes',
'changelog']``
* Elements before or after this bulleted list will be untouched by
Releases, allowing you to place e.g. paragraphs, comments etc at the top
(or bottom) of the document.
* List items are to be ordered chronologically with the newest ones on top.
* As you fix issues, put them on the top of the list.
* As you cut releases, put those on the top of the list and they will
include the issues below them.
* Issues with no releases above them will end up in a specially marked
"Unreleased" section of the rendered changelog.
* Bullet list items should use the ``support``, ``feature`` or ``bug``
roles to mark issues, or ``release`` to mark a release. These special roles
must be the first element in each list item.
* Line-items that do not start with any issue role will be considered bugs
(both in terms of inclusion in releases, and formatting) and, naturally,
will not be given a hyperlink.
* Issue roles are of the form ``:type:`number[ keyword]```. Specifically:
* ``number`` is used to generate the link to the actual issue in your issue
tracker (going by the ``releases_issue_uri`` option). It's used for both
the link target & (part of) the link text.
* If ``number`` is given as ``-`` or ``0`` (as opposed to a "real" issue
number), no issue link will be generated. You can use this for items
without a related issue.
* Keywords are optional and may be one of:
* ``backported``: Given on *support* or *feature* issues to denote
backporting to bugfix releases; such issues will show up in both
release types. E.g. placing ``:support:`123 backported``` in your
changelog below releases '1.1.1' and '1.2.0' will cause it to appear
in both of those releases' lists.
* ``major``: Given on *bug* issues to denote inclusion in feature,
instead of bugfix, releases. E.g. placing ``:bug:`22 major``` below
releases '1.1.1' and '1.2.0' will cause it to appear in '1.2.0'
**only**.
* ``(N.N+)`` where ``N.N`` is a valid release line, e.g. ``1.1`` or
``2.10``: Given on issues (usually *bugs*) to denote minimum release
line. E.g. when actively backporting most bugs to release lines 1.2,
1.3 and 1.4, you might specify ``:bug:`55 (1.3+)``` to note that bug
55 only applies to releases in 1.3 and above - not 1.2.
* A `semantic version range spec covering minor+major version numbers
<https://python-semanticversion.readthedocs.io/en/latest/reference.html#version-specifications-the-spec-class>`_
such as ``(<2.0)`` or ``(>=1.0,<3.1)``. A more powerful version of
``(N.N+)`` allowing annotation of issues belonging to specific major
versions.
.. note::
It is possible to give *both* a regular keyword
(``backported``/``major``) *and* a spec (``(N.N+)``/``(>=1.0)``) in
the same issue. However, giving two keywords or two specs at the same
time makes no sense & is not allowed.
* Regular Sphinx content may be given after issue roles and will be preserved
as-is when rendering. For example, in ``:bug:`123` Fixed a bug, thanks
`@somebody`!``, the rendered changelog will preserve/render "Fixed a bug,
thanks ``@somebody``!" after the issue link.
* Release roles are of the form ``:release:`number <date>```.
* You may place a comma-separated (whitespace optional) list of issue
numbers after the release role, and this will limit the issues included
in that release to that explicit list.
* Otherwise, releases include all relevant issues as outlined above and
in :doc:`/concepts`.
Then build your docs; in the rendered output, ``changelog.html`` should show
issues grouped by release, as per the above rules. Examples: `Releases' own
rendered changelog
<http://releases.readthedocs.io/en/latest/changelog.html>`_, `Fabric's
rendered changelog <http://www.fabfile.org/changelog.html>`_.
Optional styling additions
==========================
If you have any nontrivial changelog entries (e.g. whose description spans
multiple paragraphs or includes their own bulleted lists, etc) you may run into
`docutils' rather enthusiastic bulleted list massaging
<http://docutils.sourceforge.net/sandbox/html4strict/data/simple-lists.html>`_
which can then make your releases look different from one another.
To help combat this, it may be useful to add the following rule to the Sphinx
theme you're using::
div#changelog > div.section > ul > li > p:only-child {
margin-bottom: 0;
}
.. note::
Some themes, like `Alabaster <http://github.com/bitprophet/alabaster>`_,
may already include this style rule.
