.bashrc does not seem to be loaded

[ssbarnea]

Apparently the .bashrc file is not loaded regardless of setting the bash -l as login command.

      - name: Setup asdf
        if: ${{ !contains(matrix.shell, 'wsl') }}
        uses: asdf-vm/actions/install@v3

      - name: Install asdf inside WSL
        if: contains(matrix.shell, 'wsl')
        run: |
          set -ex
          git clone https://github.com/asdf-vm/asdf.git ~/.asdf --branch v0.14.0
          echo '. "$HOME/.asdf/asdf.sh"' >> ~/.bashrc
          export ASDF_DIR="$HOME/.asdf"
          . "$HOME/.asdf/asdf.sh"
          asdf plugin add task
          asdf install
          task --version

  	  - name: Task failing due to 'command not found'
  	    shell: "wsl-bash {0}"
        run: task --version

You can see the last task failing with command not found at https://github.com/ssbarnea/x0/actions/runs/8523493674/job/23345891540?pr=1#step:5:1

What is quite interesting is that when playing with WSL on my own host, this worked (installed asdf using commands in the first snipped and tested that another invocation of wsl would have asdf available.

wsl --install Ubuntu-22.04 --no-launch
ubuntu2204.exe --install --root
wsl --set-default Ubuntu-22.04
wsl --set-version Ubuntu-22.04 1
wsl --list -v
wsl --exec lsb_release -r

That's correct and has not much to do with this action.
.bashrc is executed when you start an interactive shell.
.bash_profile is executed when you start a login shell.

Also if I copy your steps and investigate: https://github.com/Vampire/setup-wsl/actions/runs/8530166727/job/23367453214

Your problem is the first code line of .bashrc, which is [ -z "$PS1" ] && return.
This stops executing the script if PS1 is not set which is taken as a sign that the shell is non-interactive and thus the script is stopped.

[Vampire]

So as I said, do not use .bashrc but .profile.
If you replace echo '. "$HOME/.asdf/asdf.sh"' >> ~/.bashrc by echo '. "$HOME/.asdf/asdf.sh"' >> ~/.profile it should work fine using login shell instead of interactive shell.

Does it make sense to suggest this change to asdf own install instructions?

[Vampire]

I have no idea what asdf is and whether it makes sense.
On other distributions it might not stop executing .bashrc.
And if you are using an interactive shell afair .profile will not be sourced.
So maybe they should have both in the instructions, or a prominent warning that it might not work as intended or whatever.
But you have to discuss that with the asdf maintainers.
