Core Tenets

Jujutsu's Core Tenets

Jujutsu's core tenets are:

• Separation of logic and UI: It should be easy to create new UIs (CLIs, GUIs, TUIs, servers) without having to duplicate logic.
• Easy-to-use APIs: It should be easy to create new commands. For example, each command should not have to worry about concurrency, working-copy state, and rebasing descendants of rewritten commits.
• User-friendliness: Making the working copy a commit is simpler. This is how the project started.
• The repo is the source of truth: Most commands should operate on the commit graph. The working copy is just one way of editing commits.
• Pluggable storage: Must be easy to integrate with different commit storage, virtual file systems and more.
• Git-interoperability: Git is everywhere. We need to have good interoperability to be adopted.
• All operations must be able to scale to Google-scale repos (lots of commits, lots of files): Laziness is important, must avoid accessing data unnecessarily.
• Having as few states as possible.
• Make it incredibly hard to lose work in your repo.
• Concurrent modifications to the repo should be safe.
• Allow concurrent edits on any commit, pending or finished.
• Make a "stacked diffs" workflow as easy as possible.
