A tool to help manage changes and git history between individual sub-repos and a monorepo that aggregates them.

Monorepos are convenient, but publishing projects separately - sometimes under different visibility levels (public vs private) - has real benefits. central supports a workflow that combines both, allowing changes to be promoted bidirectionally between the monorepo and each sub-repo's own published history.

This workflow used to rely on git-subrepo. .gitrepo files written by central follow the same conventions as git-subrepo's, so that the two tools' workflows stay compatible. However, central does not aim to be a full reimplementation of git-subrepo: it only ports, to OCaml, the handful of workflows we actually rely on day to day. Exact compatibility with git-subrepo is not thoroughly tested - the goal is to reduce our overall dependency footprint, and eventually remove git-subrepo from our critical path.

This repository is an early, evolving skeleton. Expect the shape of the library, CLI, and commands to change as functionality is added.
