Use variable in yaml

[zdary]

If you are looking for help, please confirm the following...

• I confirm I have searched the Docs, Codemagic Sample Projects, and GitHub Discussions.
• I confirm the software versions on my local computer match the ones in CI environment (e.g. Xcode version, Gradle version). See here
• I confirm I am able to do a fresh clone of the repository and build the project on my local computer.

Which mobile framework are you using?

React Native

Steps to reproduce

I'd like to use current git branch name which triggered the build in codemagic.yaml file

workflows:
react-native-android:
name: AU "${CM_BRANCH}" Android

The variable here doesn't resolve.

Another place I need the current branch is in script. We have .env. files in our project. We need to read variables from branch specific file.
I tried to follow the example from here https://docs.codemagic.io/knowledge-others/import-variables-from-env-file/

scripts:
  - name: Set value from "${CM_BRANCH}" "$CM_BRANCH"
    script: |
      
      source ${.env.CM_BRANCH}

Expected results

name should resolve to: AU dev Android
source ${.env.CM_BRANCH} should resolve to source .env.dev

Actual results

branch name is not resolved into the build name: AU "${CM_BRANCH}" Android
source ${.env.CM_BRANCH} is not resolved

Build id (optional)

Hey @zdary,

Please find here with below sample script for sourcing env vars from .env.dev file.

      - name: fetch env vars from
        script: |
          BRANCH_ENV_FILE=".env.${CM_BRANCH}"
          echo $BRANCH_ENV_FILE
          if [ -f "$BRANCH_ENV_FILE" ]; then
            source "$BRANCH_ENV_FILE"
            echo "FOO=$FOO" >> $CM_ENV
            echo $FOO
          else
            echo "Environment file for branch ${CM_BRANCH} not found."
          fi

Currently, the script name and workflow name resolve to a string value rather than dynamically fetching it from an env var and setting it when you run the workflow. This is expected.

thank you @himesh-cm much appreciated.
Any plans to support the name resolve in the future? This would prevent a lot of code duplication.
