GitHub action to setup Alire, the Ada/SPARK package manager.

To use the latest stable release of the Alire project, add this line to your workflow steps (you can of course pin to a version or commit rather than using latest):

    - uses: alire-project/setup-alire@latest

To use a precompiled nightly build of the development version, use the following:

    - uses: alire-project/setup-alire@latest
      with:
        version: "nightly"

To use a development version compiled from sources (if you known what you are doing), use the following:

    - uses: alire-project/setup-alire@latest
      with:
        branch: "master" # or the branch you want to use

For building from sources, the action will detect whether a GNAT is already in the PATH. If not, one will be installed to be able to build alr.

The command-line tool alr will be available in PATH after the action completes.

Check the action.yml file for more details on the available inputs.
