Git Library?

Git Library?

[Patrick Altman]

I want to write a Mac OSX UI for git.

Is there a documented/undocumented API for interacting with git in  
process?  Or would I be better off "shelling out" to the git command  
line?

Thanks,
Patrick Altman

There was a mail thread yesterday on exactly the same subject.  Bottom 
line: the recommended way is to fork()&&exec(), because I am sure you do 
not want to put in the work to make libgit.a reentrant.

Something like GitNub?

Take a look how other GUIs does it.

Not really.  GitNub is really an interface for GitHub.  I am thinking  
something more like ZigVersion, http://zigzig.com/, for Git instead of  
Subversion.

git-gui is written in TCL I believe, which I do not want to use.
GitNub is the only other GUI of sorts that i am aware of but like I  
mentioned above, that really is more of a GitHub interface and less of  
a git interface.

I think that this point I am just going to use NTask and the like in  
Cocoa/Objective-C to wrap the command line utilities.

Thanks,
Patrick

Well, I thought that GitNub is something similar to gitk, i.e. it is
history browser, but in Ruby/Cocoa instead of Tcl/Tk.

Take a look at http://git.or.cz/gitwiki/InterfacesFrontendsAndTools
page: there is a list of GUIs there.  There is gitk and git-gui,
there is QGit and varipus PyQt GUIs, there is Giggle, there is tig.

I think best would be to see how QGit does it...

That's the way I approached it when I started doing a half-hearted
attempt at exactly what you're proposing. Clone my (small) rough code
from  http://git.symonds.id.au/macgit.git

git gui works on OSX.
Aside from that, someone's already written one* :-)

Fork/exec.

If you grabbed the ugit modules you could say:

    from ugit import git

    revisions = git.rev_list(all=True).splitlines()

    file = open('msg', 'w')
    file.write("commit message." )
    file.close()

    git.commit(F='msg', s=True)

    etc, etc.

It's pretty much 90%+ of git wrapped in Python.
If a libgit.so did appear one day it would be trivial to swap out the
meta-functions in
git.py and replace them with e.g. swig replacements.  Until then,
forking out works
just fine.

stg also has Python wrapped around git so you could look there too.

* - okay, I lied. It's PyQt4.  But it does run on OSX and looks just
like any other cocoa app.
