Go bindings for [libgit2](http://libgit2.github.com/). The master branch follows the latest libgit2 release. The versioned branches indicate which libgit2 version they work against.
This project needs libgit2, which is written in C so we need to build that as well. In order to build libgit2, you need `cmake`, `pkg-config` and a C compiler. You will also need the development packages for OpenSSL and LibSSH2 installed if you want libgit2 to support HTTPS and SSH respectively.
### Stable version
git2go has versioned branches which indicate which version of libgit2 they work against. Install the development package it on your system via your favourite package manager or from source and you can use a service like gopkg.in to use the appropriate version. For the libgit2 v0.22 case, you can use
import "gopkg.in/libgit2/git2go.v22"
to use a version of git2go which will work against libgit2 v0.22 and dynamically link to the library.
### From master
The master branch follows libgit2's master branch, which means there is no stable API or ABI to link against. git2go can statically link against a vendored version of libgit2.
Run `go get -d github.com/libgit2/git2go` to download the code and go to your `$GOPATH/src/github.com/libgit2/git2go` dir. From there, we need to build the C code and put it into the resulting go binary.
libgit2 uses OpenSSL and LibSSH2 for performing encrypted network connections. For now, git2go asks libgit2 to set locking for OpenSSL. This makes HTTPS connections thread-safe, but it is fragile and will likely stop doing it soon. This may also make SSH connections thread-safe if your copy of libssh2 is linked against OpenSSL. Check libgit2's `THREADSAFE.md` for more information.
For the stable version, `go test` will work as usual. For the master branch, similarly to installing, running the tests requires linking against the local libgit2 library, so the Makefile provides a wrapper
