Elixir Git CLI

Simple wrapper of git CLI for Elixir.

Installation

Add the dependency to your mix.exs deps:

  defp deps do
    [{:git_cli, "~> 0.2"}]
  end

Usage

The usage is basically Git.COMMAND REPO, ARGS, where REPO is a Git.Repository and ARGS is either a string or a list of strings. So for example, git pull --rebase origin master would translate to Git.pull repo, ~w(--rebase origin master).

The only exceptions are Git.clone, Git.init, and Git.new, which do not take a repository as first argument.

Here are a few examples.

Git.clone Example

{:ok, repo} = Git.clone "https://github.com/tuvistavie/elixir-git-cli"
Git.remote repo, ~w(add upstream https://git.example.com)
Git.pull repo, ~w(--rebase upstream master)
Git.diff repo, "HEAD~1"
Git.add repo, "."
Git.commit repo, ["-m" "my message"]
Git.push repo
IO.puts Git.log!(repo)

Git.new Example

repo = Git.new "/path/to/existing/repo"
IO.puts Git.status! repo
Git.commit repo, ["-m" "my message"]
Git.push repo
IO.puts Git.log!(repo)

Note that all functions return :ok or {:ok, result}, and come with their bang version which only returns result when relevant. On error, the normal version returns {:error, Git.Error} and the bang version simply raises the exception.

Note

As this is a wrapper for git, you need to have the git command available on your path.

The commands are generated from git-commands.txt, except for init, clone, and new which return a Git.Repository struct and not the git process stdout. The apply command is not generated as it conflicts with elixir Kernel function. The commands with dashes have their function equivalent with dashes replaced by underscores, so for example, git ls-files become Git.ls_files.

TODO

Write more tests
Parse git log, git diff etc into struct
