ReferenceError with variables having dash in their name

[ssbarnea]

level=error msg="Unable to interpolate string 'py${{ matrix.python-version }}@${{ matrix.os }}' - [ReferenceError: 'version' is not defined]"

python-version is defined at matrix level and has special meaning for github so there is no way to change that.

Based on the error, I suspect that the parser is broken as it ends up looking for version.

I'd like to add to this, you can get around this problem by using index syntax (eg matrix["python-version"]) but this is actually invalid syntax and will fail to parse on GitHub Actions. Woops!

Example snippet

      - name: Install kubedog (for log streaming)
        # only install if its not in cache
        if: steps.kubedog_cache.outputs["cache-hit"] == 'false'

The error on GitHub Actions

Invalid workflow file
The workflow is not valid. .github/workflows/issues.yml (Line: 81, Col: 13): Unexpected symbol: '"cache-hit"'. Located at position 29 within expression: steps.kubedog_cache.outputs["cache-hit"] == 'false'

After some quick googling it seems there is a valid index syntax according to the GitHub Actions docs

As part of an expression, you may access context information using one of two syntaxes.

• Index syntax: github['sha']
• Property dereference syntax: github.sha

Well... some poking around the codebase lead me to the previous discussion of this issue (#104) and the already-implemented fix (#287) in master 😅
