Diff

Working directory diff

Compare the current working tree against HEAD:

let diff = try repo.diff()
for file in diff {
    print(file.path, file.status)
    for hunk in file.hunks {
        print(hunk.header)
        for line in hunk.lines {
            print(line.origin, line.content)
        }
    }
}

Diff from a commit

let commit = try repo.log(limit: 1).first!
let diff = try repo.diff(from: commit)

Diff between two commits

let commits = try repo.log(limit: 2)
let diff = try repo.diff(from: commits[1], to: commits[0])
