Pre-compute the next version with semantic-release

A composite action that pre-computes the next version of a project using semantic-release.
This action must be used in a repository with semantic-release configured.

Due to a limitation in semantic-release configuration, this action only works if the semantic-release config file is in the format release.config.js. Other formats like json, yaml, etc. are not compatible with the use of this action.

Rationale

In some projects, it might be useful to compute the next release version before publishing a release. With semantic-release this operation is not possible out-of-the-box, and for this reason, this action will do it for you!

Action usage

Inputs	Description
`working-directory`	The path in which the action should runs
`github-token`	The token needed by semantic-release to run

Outputs	Description
`will-release`	Set to `true` if a new release will be triggered. Set to `false` if no release will be triggered.
`next-version`	Contains the next version if `will-release` is `true`. Contains an empty string if `will-release` is set to `false`.

Example

The following example shows how to use the action.

jobs:
  test:
    - name: Checkout repo
      uses: actions/checkout@v3.3.0
    - name: Pre-compute the next version
      id: compute-next-version
      uses: nicolasfara/precompute-semantic-release-version-action@1.0.0
      with:
        github-token: ${{ secrets.GITHUB_TOKEN }}
    - name: Use the next version
      run: |
        echo "Will release: ${{ steps.compute-next-version.outputs.will-release }}"
        echo "The next version is ${{ steps.compute-next-version.outputs.next-version }}"
