PROS Build Action

This action creates an environment capable of building PROS projects and templates, and builds them using build.sh

• name
  • The recommended name for an artifact.

Example Workflow

        id: test
        uses: LemLib/pros-build

Using the Container in your own build script

If you wish to use your own build script using this container as a base, you can do so with the following:

It by default includes the packages built into the Ubuntu docker image, and contains the additional packages below:

wget (Used to download the toolchain)
git (Used to get the HEAD SHA hash)
gawk (Used to get lines from the user project's Makefile)
python3-minimal (Minimal installation of Python used for pros-cli)
python3-pip (Used to install pros-cli in the Dockerfile)
unzip (Unzips the template so that it can be uploaded to Github Actions)
pros-cli (through python)

Editing the Dockerfile

FROM ghcr.io/LemLib/pros-build:stable

# Remove the included build script.
RUN rm -rf /build.sh

## Do what you wish here, such as copying your own build script in, add dependencies, etc

# Override ENTRYPOINT with your own. This isn't strictly necessary if you name your build script build.sh and put it in the root of the container (Such as /build.sh)
ENTRYPOINT []
