This is a GitHub Action that increments an environment variable. If environment variable does not exist, it will create it and set it to 1.

          uses:  MandalAutomations/Increment-Environment-Variable@v1

Required String Name for the variable to increment. Whitespace is replaced with _.

Required String Environment Name

Required String Repository ID can be found using ${{ github.repository_id }}

Required String Personal Access Token (PAT). The built-in GITHUB_TOKEN cannot write environment variables, so a PAT is required.

Required scopes:

• Classic PAT: repo
• Fine-grained PAT, on the target repository: Variables: Read and write and Environments: Read and write

• If the variable does not exist, it is created with value 1.
• If the variable exists and its value is a non-negative integer, it is incremented by 1.
• If the variable exists but its value is not a non-negative integer, the step logs a warning and exits successfully without changing anything.
