Hot on the heels of another Git-related article that was making the rounds recently, I was reminded of Git’s own structure and how it influences user experience. Specifically what we assume is part of how Git works, is actually a part of the porcelain (in Git speak, the user interface and commands that back it). As someone developing a Git client, it’s interesting to think Git’s user experience could be significantly different with a different interface, particularly because people have a particular mental model of Git influenced by the default interface. Said influence is enough that libgit2’s API emulates the porcelain’s semantics, in-process.
