Subject: Proposal/Discussion: Turning parts of Git into libraries From: Emily Shaffer To: Git List Date: Fri, 17 Feb 2023 13:12:23 -0800=09=20=20=20=20 https://lore.kernel.org/git/CAJoAoZ=3DCig_kLocxKGax31sU7Xe4=3D=3DBGzC__= Bg2_pr7krNq6MA@mail.gmail.com/ And some patches are starting to float around. https://public-inbox.org/git/20230810163346.274132-1-calvinwan@google.com/ > I digress, but I wonder: is there not even a viable Haskell or OCaml > implementation of Git? It depends on what means =E2=80=9Cviable=E2=80=9D. :-) https://github.com/mirage/ocaml-git https://hackage.haskell.org/package/git Irmin [1] is an OCaml library for building mergeable, branchable distributed data stores =E2=80=93 A Distributed Database Built on the Same Principles as Git. And irmin relies on ocaml-git. 1: https://github.com/mirage/irmin Then there is a pure Go implementation and another using Java. https://git-scm.com/book/en/v2/Appendix-B%3A-Embedding-Git-in-your-Applicat= ions-go-git https://git-scm.com/book/en/v2/Appendix-B%3A-Embedding-Git-in-your-Applicat= ions-JGit I do not know all that are =E2=80=9Cviable=E2=80=9D. Well, I do not know i= f =E2=80=99git gc=E2=80=99 is implemented. And I do not know which plumbing is implemented and which porcelain is available. Last, SWH uses dulwich [2] which is a pure Python implementation of Git. 2: https://www.dulwich.io/ To my knowledge, there is no =E2=80=9Cdulwich gc=E2=80=9D but they implemen= t =E2=80=9Cdulwich fsck=E2=80=9D and =E2=80=9Cdulwich repack=E2=80=9D. Back on 10 Years of Guix or at UNESCO on February =E2=80=93 I do not rememb= er exactly when =E2=80=93 we were discussing about implementation of Git. And= we mentioned an implementation in Rust. Maybe this one: https://github.com/Byron/gitoxide Cheers, simon
