Releasing
=========
This describes for the maintainers of RGBDS how to publish a new release on
GitHub.
1. Update, commit, and push `include/version.h <include/version.h>`__ with
values for ``PACKAGE_VERSION_MAJOR``, ``PACKAGE_VERSION_MINOR``,
``PACKAGE_VERSION_PATCH``, and ``PACKAGE_VERSION_RC``. Only define
``PACKAGE_VERSION_RC`` if you are publishing a release candidate! You can
use ``git commit -m "Release <version>"`` and ``git push origin master``.
2. Create a Git tag formatted as ``v<MAJOR>.<MINOR>.<PATCH>``, or
``v<MAJOR>.<MINOR>.<PATCH>-rc<RC>`` for a release candidate. ``MAJOR``,
``MINOR``, ``PATCH``, and ``RC`` should match their values from
`include/version.h <include/version.h>`__. You can use ``git tag <tag>``.
3. Push the tag to GitHub. You can use ``git push origin <tag>``.
GitHub Actions will run the `create-release-artifacts.yaml
<.github/workflows/create-release-artifacts.yaml>`__ workflow to detect the
tag starting with "``v[0-9]``" and automatically do the following:
1. Build 32-bit and 64-bit RGBDS binaries for Windows with ``cmake``.
2. Package the binaries into zip files.
3. Package the source code into a tar.gz file with ``make dist``.
4. Create a draft GitHub release for the tag, attaching the three
packaged files. It will be a prerelease if the tag contains "``-rc``".
If an error occurred in the above steps, delete the tag and restart the
procedure. You can use ``git push --delete origin <tag>`` and
``git tag --delete <tag>``.
4. GitHub Actions will run the `create-release-docs.yml
<.github/workflows/create-release-docs.yml>`__ workflow to add the release
documentation to `rgbds-www <https://github.com/gbdev/rgbds-www>`__.
For a release candidate, which creates a prerelease, you will have to
take these steps yourself.
1. Clone `rgbds-www <https://github.com/gbdev/rgbds-www>`__. You can use
``git clone https://github.com/gbdev/rgbds-www.git``.
2. Make sure that you have installed ``groff`` and ``mandoc``. You will
need ``mandoc`` 1.14.5 or later to support ``-O toc``.
3. Run ``.github/actions/get-pages.sh -r <path/to/rgbds-www> <tag>``. This
will render the RGBDS documentation as HTML and PDF and copy it to
``rgbds-www``.
If you do not have ``groff`` installed, you can change
``groff -Tpdf -mdoc -wall`` to ``mandoc -Tpdf -I os=Linux`` in
`.github/actions/get-pages.sh <.github/actions/get-pages.sh>`__ and it
will suffice.
4. Commit and push the documentation. You can use ``git commit -m
"Create RGBDS <tag> documentation"`` and ``git push origin master``
(within the ``rgbds-www`` directory, not RGBDS).
5. Write a changelog in the GitHub draft release.
6. Click the "Publish release" button to publish it!
7. Update the `release` branch. You can use ``git push origin release``.
