SwiftGit2

Swift bindings to libgit2.

let URL: URL = ...
let result = Repository.at(URL)
switch result {
case let .success(repo):
    let latestCommit = repo
        .HEAD()
        .flatMap {
            repo.commit($0.oid)
        }

switch latestCommit {
case let .success(commit):
    print("Latest Commit: \(commit.message) by \(commit.author.name)")

case let .failure(error):
    print("Could not get commit: \(error)")
}
case let .failure(error):
    print("Could not open repository: (error)")
}

Design

SwiftGit2 uses value objects wherever possible. That means using Swift’s

struct

enum

1. Values can be used concurrently.
2. Consuming values won’t result in disk access.
3. Disk access can be contained to a smaller number of APIs.

This vastly simplifies the design of long-lived applications, which are the most common use case with Swift. Consequently, SwiftGit2 APIs don’t necessarily map 1-to-1 with libgit2 APIs.

All methods for reading from or writing to a repository are on SwiftGit’s only

class

Repository

struct

enum

Required Tools

To build SwiftGit2, you'll need the following tools installed locally:

• cmake
• libssh2
• libtool
• autoconf
• automake
• pkg-config

brew install cmake libssh2 libtool autoconf automake pkg-config

Adding SwiftGit2 to your Project

The easiest way to add SwiftGit2 to your project is to use Carthage. Simply add

github "SwiftGit2/SwiftGit2"

Cartfile

carthage update

If you’d like, you can do things the ~~hard~~ old-fashioned way:

1. Add SwiftGit2 as a submodule of your project’s repository.
2. Run

   git submodule update --init --recursive

   to fetch all of SwiftGit2’s depedencies.
3. Add

   SwiftGit2.xcodeproj

   to your project’s Xcode project or workspace.
4. On the “Build Phases” tab of your application target, add

   SwiftGit2.framework

   to the “Link Binary With Libraries” phase. SwiftGit2 must also be added to a “Copy Frameworks” build phase.
5. If you added SwiftGit2 to a project (not a workspace), you will also need to add the appropriate SwiftGit2 target to the “Target Dependencies” of your application.

Building SwiftGit2 Manually

If you want to build a copy of SwiftGit2 without Carthage, possibly for development:

1. Clone SwiftGit2
2. Run

   git submodule update --init --recursive

   to clone the submodules
3. Build in Xcode
