julia-release

An action to proctor the CD (release and registering) of a julia project. Use the action to automate the detection of an update to the version in your Project.toml, and from that, automate the creation of a GitHub release and the Registrator comment on the commit tagged by that release.

- name: Julia 🔴🟢🟣 Release 🚰 and Register 📦
  uses: Skenvy/julia-release@v1
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

A github action to automate the release and registration of a Julia package (via the Registrator bot, so will require it to be installed).

It will detect any commit to a designated deployment_branch that updates the project version in the required <subdirectory>/Project.toml, and create a release and registration for it.

This is the ideological reverse order of the standard julia TagBot, which creates github releases of commits after manually registering them. Instead, this action, when set up in the recommended way, will, if it detects a change to the version, create a release, and comment the "@JuliaRegistrator register" command on the commit that it has released, for a truly continuous deployment strategy; CD.

Inputs

deployment_branch

• Required
• Name of branch from which against to deploy; e.g. master|main|trunk|other.

subdirectory

• Optional
• The path to the folder/subdirectory containing the Pkg's Project.toml.
• Default ".".

changelog

• Optional
• An optional changelog with which to generate notes in the release.
• Default "".

release_tag_template

• Optional
• A template to generate the release tag. Exposes "<NEW_VERSION>". ("/" will be replaced with "_").
• Default "v<NEW_VERSION>".

release_name_template

• Optional
• A template to generate the release name. Exposes "<NEW_VERSION>".
• Default "Version: <NEW_VERSION>".

auto_release

• Optional
• Whether to automatically release your new version.
• Default true.

auto_register

• Optional
• Whether to automatically register your new release.
• Default true.

Outputs

new_version

• The new version listed in project.

old_version

• The old version listed in project.

diff_from

• The sha of the "previous head of the deployment branch" that is used to check for a change in the version.

diff_to

• The sha of the commit that is taken as the current ~ which without frobbing the head will be the github_sha.

Example usage

Optional: The on: to use for the workflow

• For a deployment_branch of main, and a subdirectory of path/to/your
• Even if you use the default subdirectory that is "." ~ the project root, it's still advised to speficically target './Project.toml' for the workflow, if calling this is it's primary intent, to not over trigger it.

on:
  push:
    branches:
    - 'main'
    paths:
    - 'path/to/your/Project.toml'

Required: In jobs.<job_id>.runs-on:

• This is a docker job, so you'll need;

runs-on: 'ubuntu-latest' # docker jobs not supported on windows or mac

Required: In jobs.<job_id>.steps[*]

• Prior to the uses: Skenvy/julia-release@v1 step, you'll need to checkout with depth 0, as this action checks the diff against older commits. If you only allow squashes, a checkout depth greater than 1 might be ok, although 0 is recommended.

- name: 🏁 Checkout
  uses: actions/checkout@v3
  with:
    fetch-depth: 0

In jobs.<job_id>.steps[*].uses:

• For a package project located at the root ./Project.toml, with the deployment branch being main, in the least decorated way;

- uses: Skenvy/julia-release@v1
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
  with:
    deployment_branch: 'main'

• For a package project located at ./path/to/your/Project.toml, with optionally more verbose release tag and name, and a pretty step name.

- name: Julia 🔴🟢🟣 Release 🚰 and Register 📦
  uses: Skenvy/julia-release@v1
  id: release_step
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
  with:
    deployment_branch: 'main'
    subdirectory: "path/to/your"
    release_tag_template: "julia-v<NEW_VERSION>"
    release_name_template: "Julia: Version <NEW_VERSION>"

• Although "registering" via the Registrator bot is a primary intent of this, if you simply want to automate releases, but not automate the registration, you can prevent the registrator comment with;

- uses: Skenvy/julia-release@v1
  ...
  with:
    ...
    auto_register: false

• If you are restrictive about which actions you're happy to supply your $GITHUB_TOKEN to, the release and registration can both be disallowed, while still setting outputs to be used elsewhere of ${{ steps.julia_release.outputs.<OUTPUT_NAME> }} for the outputs mentioned above of new_version, old_version, diff_from, and diff_to;

- uses: Skenvy/julia-release@v1
  id: julia_release
  with:
    deployment_branch: 'main'
    auto_release: false
    auto_register: false

A full example

The motivation in making this was to simplify the CI steps to not have to manually summon the registrator bot and not have to rely on the tagbot to create releases after after commenting the registrator bot to "release" them. See it used below in a minimal example, or see it used in the place it was originally designed for here, and the test working that calls here.
