Geef is a simple Erlang NIF that exposes some of the libgit2 library functions to Erlang.
First you need to install libgit2:
$ git clone git://github.com/libgit2/libgit2.git
$ cd libgit2
$ make
$ make install
Now, if you have Erlang OTP_R13B04 installed, you can compile this NIF to run in it.
$ git clone git://github.com/schacon/geef.git
$ cd geef
$ make
Now you should have a .beam file you can load. I've also included an example escript to test some of the functions (currently just hex_to_raw and object_exists):
$ ./geef h2r de08fe4884650f067bd5703b8a59a8b3b3c99aaa
Raw: <<222,8,254,72,132,101,15,6,123,213,112,59,138,89,168,179,179,201,154,170>>
$ ./geef exists .git/objects 89c86150c8b164f441a73f4991b2c339fd4aae7c
Exists: true
$ ./geef exists .git/objects 87fcfb277899097823911006f438658ce86b3697
Exists: false
The API looks basically like this:
geef:start().
Raw = geef:hex_to_raw(HexSha).
Exists = geef:object_exists(ObjectsPath, HexSha).
Fork schacon/geef on GitHub, make it awesomer (preferably in a branch named for the topic), send a pull request.
