This action makes the protoc compiler available to Workflows.

To get the latest stable version of protoc just add this step:

- name: Install Protoc
  uses: Arduino/actions/setup-protoc@master

If you want to pin a major or minor version you can use the .x wildcard:

- name: Install Protoc
  uses: Arduino/actions/setup-protoc@master
  with:
    version: '3.x'

You can also require to include releases marked as pre-release in Github using the include-pre-releases flag (the dafault value for this flag is false)

- name: Install Protoc
  uses: Arduino/actions/setup-protoc@master
  with:
    version: '3.x'
    include-pre-releases: true

To pin the exact version:

- name: Install Protoc
  uses: Arduino/actions/setup-protoc@master
  with:
    version: '3.9.1'

To work on the codebase you have to install all the dependencies:

# npm install

To run the tests:

# npm run test

Additional log events with the prefix ::debug:: can be enabled by setting the secret ACTIONS_STEP_DEBUG to true.

See step-debug-logs for reference.

We check in the node_modules to provide runtime dependencies to the system using the Action, so be careful not to git add all the development dependencies you might have under your local node_modules. To release a new version of the Action the workflow should be the following:

1. npm install to add all the dependencies, included development.
2. npm run test to see everything works as expected.
3. npm run build to build the Action under the ./lib folder.
4. rm -rf node_modules to remove all the dependencies.
5. npm install --production to add back only the runtime dependencies.
6. git add lib node_modules to check in the code that matters.
7. open a PR and request a review.
