The Makefile is used for managing files and maintaining code quality. It includes a default help target that prints all make targets and their descriptions grouped by function.

Some Makefile targets for basic formatters and linters are included along with GitHub Actions pre-submits. Versioning of these tools is done via the requirements.txt and packages.json. This is so that the versions can be maintained and updated via dependabot-like tooling.

Required runtimes:

• node: Node.js is required to run some linters and formatters.
• python: Node.js is required to run some linters and formatters.

The following tools need to be installed:

• actionlint: For linting GitHub Actions workflows.
• shellcheck: For linting shell code in GitHub Actions workflows.

The following tools are installed locally:

• yamllint: For YAML (e.g. GitHub Actions workflows). (installed in Python virtualenv .venv).
• prettier: For formatting markdown and YAML (installed in local node_modules).
• markdownlint: For linting markdown (installed in local node_modules).

Makefile targets and linter/formatter configuration are designed to respect .gitignore and not cross git submodules boundaries. However, you will need to add files using git add for new files before they are picked up.

Makefile targets for linters will also produce human-readable output by default, but will produce errors as GitHub Actions workflow commands so they can be easily interpreted when run in Pull-Request status checks.
