Ole Martin developed an automated pull request creation workflow for subtree synchronization in the Altinn/altinn-studio repository. Using Makefile and shell scripting, Ole designed a process that creates a new branch, synchronizes the subtree, and leverages the GitHub CLI to push changes and open a pull request. The workflow includes validation to ensure operations begin from the main branch and prevents duplicate branches, while also supporting interactive conflict resolution. A dedicated target allows for manual PR creation when needed. This work streamlined subtree management, reduced manual intervention, and improved release consistency, demonstrating a focused application of automation and DevOps practices.
