manage array fields

[gpongelli]

Hi, trying this action seems that TOML's array are extracted as string, having then no way to interact with it.

Is it possible to have an array object as "value" output ?

I've following situation:

pyproject.toml:

[tool.poetry]
    ...
    authors = ["Gabriele Pongelli <gpongelli@users.noreply.github.com>"]

github action :

      - name: get authors from toml
        uses: SebRollen/toml-action@v1.2.0
        id: read_toml_authors
        with:
          file: 'pyproject.toml'
          field: 'tool.poetry.authors'
...
       ${{ join(steps.read_toml_authors.outputs.value, ', ') }}

the join seems not working, I still have ["Gabriele Pongelli <gpongelli@users.noreply.github.com>"] as join's output instead of the expected "Gabriele Pongelli <gpongelli@users.noreply.github.com>" (square brackets should not be there after join, if the input is an array), so I think this action does not provide an array as output.

Can you please fix your action to handle this case ?

Thanks.

Hi @gpongelli

Not sure if this is possible. Outputs from an action are always converted to unicode strings, see https://docs.github.com/en/actions/using-jobs/defining-outputs-for-jobs

In your case, the array is formatted using valid JSON, so you should be able to use fromJSON to parse it before calling join
