Publish-PSModule

Creates a GitHub release and publishes the PowerShell module to the PowerShell Gallery.

This GitHub Action is a part of the PSModule framework. It is recommended to use the Process-PSModule workflow to automate the whole process of managing the PowerShell module.

Specifications and practices

Publish-PSModule follows:

• SemVer 2.0.0 specifications
• GitHub Flow specifications
• Continiuous Delivery practices

... and supports the following practices in the PSModule framework:

• PowerShell publishing guidelines

How it works

The workflow will trigger on pull requests to the repositorys default branch. When the pull request is opened, the action will decide what to do based on labels on the pull request.

It will get the latest release version by looking up the versions in GitHub releases, PowerShell Gallery and the module manifest. The next version is then determined by the labels on the pull request. If a prerelease label is found, the action will create a prerelease with the branch name (in normalized form) as the prerelease name. By defualt, the following labels are used:

• For a major release, and increasing the first number in the version use:
  • major
  • breaking
• For a minor release, and increasing the second number in the version.
  • minor
  • feature
• For a patch release, and increases the third number in the version.
  • patch
  • fix

The types of labels used for the types of prereleases can be configured using the MajorLabels, MinorLabels and PatchLabels parameters/settings. See the Usage section for more information.

When a pull request is merged into the default branch, the action will create a release based on the labels and clean up any previous prereleases that was created.
