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)")
}SwiftGit2 uses value objects wherever possible. That means using Swift’s structs and enums without holding references to libgit2 objects. This has a number of advantages:
- Values can be used concurrently.
- Consuming values won’t result in disk access.
- 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. This highlights the failability and mutation of these methods, while freeing up all other instances to be immutable structs and enums.
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
The easiest way to add SwiftGit2 to your project is to use Carthage. Simply add github "SwiftGit2/SwiftGit2" to your Cartfile and run carthage update.
If you’d like, you can do things the hard old-fashioned way:
- Add SwiftGit2 as a submodule of your project’s repository.
- Run
git submodule update --init --recursiveto fetch all of SwiftGit2’s depedencies. - Add
SwiftGit2.xcodeprojto your project’s Xcode project or workspace. - On the “Build Phases” tab of your application target, add
SwiftGit2.frameworkto the “Link Binary With Libraries” phase. SwiftGit2 must also be added to a “Copy Frameworks” build phase. - 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.
If you want to build a copy of SwiftGit2 without Carthage, possibly for development:
- Clone SwiftGit2
- Run
git submodule update --init --recursiveto clone the submodules - Build in Xcode
