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/carlosmn/geef.git
$ cd geef
$ make
$ mix # if you want to build the elixir modules
The API looks basically like this:
{ok, Repo} = geef_repo:open(".").
Workdir = geef_repo:workdir(Repo).
{ok, Blob} = geef_blob:lookup(Repo, geef_oid:parse("abcde...")).Most functions are available from the elixir modules so you can make use of some elixir-specific
things, like Repository.open!, or Reference.resolve!.
alias Geef.Repository alias Geef.Reference repo = Repository.open!(".") ref = Reference.lookup!(repo, "HEAD") |> Reference.resolve!
references, objects, etc are elixir records. Trees implement the Access protocol
%Reference{name: name} = Reference.lookup!(repo, "refs/heads/master") IO.puts name {:ok, tree} = Tree.lookup(repo, "abcde...") IO.inspect tree["src/geef_pkt.erl"]
