5.1 Preparing a Release *ale-development-release*
ALE offers release packages through GitHub, for two reasons:
1. Some users like to target specific release versions rather than simply
installing the plugin from `master`. This includes users who create Linux
distribution specific packages from GitHub releases.
2. The releases provide a nice way to get an overview of what has changed in
ALE over time.
ALE has no fixed release schedule. Release versions are created whenever the
ALE developers feel the need to create one. ALE release versions follow the
typical Semantic Versioning scheme. See: https://semver.org/
Minor version releases for ALE should be the most common, followed by patch
releases. Every minor version release should be followed by a `vA.B.x` branch
such as `v2.0.x` for version `2.0.0` and every following patch version before
`2.1.0`. The `git` branch strategy for patches is to first merge a bug fix to
`master`, and then `git cherry-pick` a patch to a branch for a specific
version. ALE developers do not generally support anything but `master` or the
last minor version.
Generally ALE releases hit a major version only when there are breaking
changes to a public ALE setting or function. A "public" setting or function is
defined as any setting or function documented in the `:help` |ale| text file.
Major ALE versions ought to be so rare that they only come once a year at
most. ALE should not typically introduce any breaking changes.
If there are ever to be any breaking changes made for ALE, there should first
come a minor version release for ALE documenting all of the coming breaking
changes to ALE. It should be described how users can prepare for a breaking
change that is coming before it is done.
To create a release for ALE, you will need sufficient permissions in GitHub.
Once you do, follow these steps.
1. Create a new release draft, or edit an existing one. It helps to craft
drafts ahead of time and write the last commit ID checked for release notes
on the last update to a draft.
See the releases page: https://github.com/dense-analysis/ale/releases
2. Examine `git log` and read changes made between the last ID checked, or the
git tag of the previous release, and the current commit in `master`.
3. Write updates in separate sections (except where empty) for:
3.a. Breaking Changes
3.b. Deprecated Features
3.c. New Features
3.d. New Linters
3.e. New Fixers
3.f. Linter Enhancements
3.g. Fixer Enhancements
3.h. Bugs Fixed
4. Once you've finished writing the draft for the release, bump
`s:current_ale_version` in `autoload/ale.vim` to the current version, and
add a line to `test/test_ale_has.vader` to test for the version. See
|ale#Has()| documentation for more information.
5. Commit the changes after `./run-tests --fast -q` passes.
6. Tag the release with `git tag vA.B.C`, replacing `A`, `B`, and `C` with the
version numbers. See `git tag --list` for examples.
7. Run `git push` and `git push --tags` to push the commit and the tag.
8. Edit the release draft in GitHub, select the tag you just pushed, and
publish the draft.
9. If you're creating a new major or minor version: `git checkout -b vA.B.x`,
replacing `A` and `B` with the major and minor versions. `git push` the new
branch, and the GitHub branch protection settings should automatically
apply to the new release branch.
10. You have already completed the last step.
Have fun creating ALE releases. Drink responsibly, or not at all, which is the
preference of w0rp.
