Getting repo full path in custom workflow step

[tapaszto]

I need to get the full path of the cloned repo in a custom workflow step.

workflows:
  default:
    plan:
      steps:
      - run: sh -c /mnt/scripts/myscript.sh
      - init
      - plan

There is a specific file in the repo containing input data, the execution of myscript needs to read this file and perform initialization before plan and apply - the specific file in the repo contains reference to an Azure KeyVault, myscript reads the KeyVault and fill some additional environment variables defined in the KeyVault, mostly secrets .
Is there any predefined system environment variable effective during the execution of myscript that myscript can read in order to figure out the location of the cloned repo and the full path of the specified file in it?

What I found in the doc:
DIR - Absolute path to the current directory.

Is this the environment variable I am looking for?

$DIR and $PWD should both point to the checked out repo, eg:

DIR=/home/atlantis/.atlantis/repos/tekumara/atlantis-example/1/default
PWD=/home/atlantis/.atlantis/repos/tekumara/atlantis-example/1/default

FYI, you'll also have:

HEAD_REPO_OWNER=tekumara
HEAD_REPO_NAME=atlantis-example
PULL_NUM=1
WORKSPACE=default
