C# Git Implementation

C# Git Implementation

[JD Guzman]

Hello I am new to the list and if I am not following some kind of list
ettiquite please let me know. 

I read in the archives that there was once talk of porting Git over to C#
and was wondering if anything ever came of this?  I realize there were some
that didn't see the use for this but as Git is becoming more and more
popular a more native implementation of Git for windows users would be a
good endevour IMHO.

At any rate any info would be greatly appreciated.

Regards,

JD Guzman

There were several efforts made, but these have fallen by the wayside.

Since then, the mingw/msys port has made progress to the point where
git will use native calls. Most - if not all of this - has been merged
back into upstream git as of version 1.6.

Git works well on Windows and msysGit even provides a native installer
that installs the necessary companion tools and libraries.

Therefore, there is already a native version of Git for Windows that
is always up-to-date with the latest Git functionality (since it is
the same sourcecode!)

BTW: Kudos to everyone involved in the Windows port.

That depends. I think it's happened at least on three different occasions
that someone wants to port git to C#. The latest is the attempt to write a
libified git (in C) that will be DllImport()'ed from C#, which the devs at
MonoDevelop were sort of interested in. I'm currently working (very slowly)
on libgit2, and it's nowhere near usable today.

Truly. However, a better way forward is to create a portable git library
that any old application can use, no matter what language the application
is written in. That way, GUI-hackers can add all the bells and whistles
they like.

Besides that, msysgit works very well on Windows.

libgit2 is available from
http://www.spearce.org/projects/scm/libgit2/libgit2.git
git://git.op5.org/git/libgit2.git

The first URL belongs to Shawn O. Pearce, the initiator of the libgit2
project. The second one is where I stash random stuff that I work on.
Note that git.op5.org is subject to heavy rebasing at the moment, as I'm
basically using it as a patch queue for Shawn (and everyone else who's
interested) to look at when they feel like it. It's not yet interesting
enough to warrant sending everything as patches to git@vger, but a small
bunch of people are helping making the small internal API's reliably
portable (filesystem operations, thread-local error handling) so that
we can nail them down hard to prevent having to change them (and their
hundreds of callers) in the future.

Is it possible to compile the Java-language jgit with the Common Language 
Runtime and access that from a C# application?

I tried it half a year ago. Recompiling and running was easy, Unfortunately it hung on reading
blobs and  the stacktrace showed it was stuck in deflate. It's not very high on my list of priorities,
but I assume fixing the problem is probably not hard if you decide to get your editor dirty.

Hi,
Just in case some of you are still interested in a git implementation in C#.
I evaluated all of the existing projects and chose the one of them which was
most advanced and had the most promising strategy of getting done soon:
kevin thompsons gitty. gitty is a  port of about 6k of ~20k lines of a jgit
snapshot from 2008. The gitty code is mostly not working because it has
never been debugged after porting.
 
I figured that the easiest way to a pure c# implementation of git is to port
jgit. Automatic porting attempts have not really been successful so I
decided to do it manually. Based on Kevin's very erraneous but yet valuable
work I ported even more substantial parts of jgit and its tests to C# and
got much of the code working as the over 200 passing tests can tell. By now
we have ported about 47% of the jgit source (snapshot from june 2009) and
got reading of repos and writing of trees, blobs and commits to work
already. The project is called Git# now and has already found a few
contributors on github. More info is available at the 
http://www.eqqon.com/index.php/GitSharp Git#  website.

I know that there have been several attempts by the Mono project to create a
git implementation in C#. They seem inactive and in a very basic state to me
but correct me if I am wrong. I will try to contact the mono folks for
collaboration on the matter.

I hope portable git library, which can port to any languadge and platform.
Git itself use such library. So library can be verified at big scope.
