Export environment variables from config

[reitzig]

I want make use of setting environment variables through mise, attempting to replace direnv in simple cases at least.

Unfortunately, the action does not export the variables included in the configuration:

Example config:

Example workflow:

The build subsequently fails because changie doesn't find its config.

Workaround:

    - uses: jdx/mise-action@v2
      with:
        install: false # we only need env

    - name: Load mise env
      run: |
          mise env -s bash \
              | grep -v 'export PATH=' \
              | cut -d' ' -f2 \
              >> "$GITHUB_ENV"

this is painful, should probably be fixed under an option

I stumbled on this code in direnv: https://github.com/direnv/direnv/blob/master/internal/cmd/shell_gha.go

I'm not entirely sure how it works, but it might be useful here since I am pretty sure it's solving a similar problem

Original workaround didn't work for me, since for some reasons I would get double quoted ENV values sometimes, e.g.:

MY_VAR="'my_value'"

Found the following to be working instead (it's also cleaner):

- name: Load mise env
  run: mise env --dotenv >> "$GITHUB_ENV"
