fastlane/monorepo

The fastlane monorepo project is a set of scripts designed to help consolidate multiple separate code repositories into a single, unified one. This process, known as migrating to a monorepo, is something teams do when they want all their related projects living together in one place instead of being scattered across many different repositories. At a high level, the scripts handle three main tasks to make this transition smooth. First, one script moves the actual source code from the individual repositories into the new shared home. Second, another script updates all the web links pointing to the old repository locations, redirecting them to the correct folders inside the new, combined repository. Third, a final script migrates all the existing GitHub issues, the bug reports and feature requests people have filed, so that conversation history isn't lost in the move. This kind of tool would be used by maintainers of open-source projects or engineering teams who have outgrown a multi-repo setup. For example, if a project like fastlane started with separate repositories for each tool or plugin, over time the team might find it easier to manage everything in one place, sharing configuration, running tests across the whole project at once, and reducing the overhead of keeping multiple repositories in sync. These scripts automate what would otherwise be a tedious, error-prone manual process. The README doesn't go into much detail about the specific mechanics of how each script works under the hood, and points to an external blog post for more context. The scripts are written in Ruby, and given the small number of stars and the specialized nature of the task, this appears to be a utility built to solve a specific one-time migration need rather than an ongoing, general-purpose tool.
