Playing around with git's objects
Repository
Opening an existing git repository
var repo=new Repository("path/to/repo")
Now suppose you have created some new files and want to commit them
repo.Index.Add("README", "License.txt");
var commit=repo.Commit("My first commit with gitsharp", new Author("henon", "meinrad.recheis@gmail.com"));
Easy, isn't it? Now let's have a look at the changes of this commit:
foreach(var change in commit.Changes) Console.WriteLine(change.Name + " " + change.ChangeType);
Get the staged changes from the index
repo.Status.Added.Contains("README")
Access and manipulate the configuration
repo.Config["core.autocrlf"]="false"
Commit
Get the message of the previous commit
new Commit(repo, "HEAD^").Message
Print a list of changes between two commits c1 and c2:
foreach(var change in c1.CompareAgainst(c2))
Console.WriteLine(change.ChangeType+": "+change.Path);
Print all previous commits of HEAD of the repository repo
foreach(var commit in repo.Head.CurrentCommit.Ancestors)
Console.WriteLine(commit.ShortHash+": "+commit.Message+", "+commit.Author.Name+", "+commit.AuthoredDate);
Tree & Leaf
Get the root tree of the most recent commit
var tree = repo.Head.CurrentCommit.Tree
It has no Parent so IsRoot should be true
Debug.Assert(tree.Parent==null);
Debug.Assert(tree.IsRoot);
Now you can browse throught that tree by iterating over its child trees
foreach(var subtree in tree.Trees) { ... }
Or printing the names of the files it contains
foreach(var leaf in tree.Leaves) { Console.WriteLine( leaf.Path); }
Blob
A Leaf is a Blob and inherits from it a method to retrieve the data as a UTF8 encoded string:
new Blob(repo, "e287f54").Data
Blob also let's you access the raw data as byte array
new Blob(repo, "e287f54").RawData
Branch
Get the current branch
var branch=repo.CurrentBranch
Console.WriteLine("Current branch is "+branch.Name);
Another way to get the current branch
repo.Head
Get master branch
var master = new Branch(repo, "master");
Get the abbreviated hash of the last commit on master
master.CurrentCommit.ShortHash
Reset the branch to a previous commit (hard or soft)
master.ResetHard("HEAD^")
master.ResetSoft("HEAD^")
Ref
You can use Ref to resolve typical git references without needing to know their type. The following expression should be true if "version1.0.0" is a Tag and not a Branch.
new Ref(repo, "version1.0.0").Target.IsTag
Branch is a Ref, but not all Ref's necessarily need to be branches. For instance, we want to get the message of the previous commit:
(new Ref(repo, "HEAD^").Target as Commit).Message
Using git commands
Init
Initializing a new repository in the current directory (if GID_DIR environment variable is not set)
GitSharp.Commands.Init();
Initializing a new repository in the specified location
GitSharp.Commands.Init("path/to/repo");
Initializing a new repository with options
var cmd = new GitSharp.InitCommand("path/to/repo") { Quiet=false, Bare=true };
cmd.Execute();
Clone
Clone a repository from a public repository via http
GitSharp.Commands.Clone("git://github.com/henon/GitSharp.git", "path/to/local/copy");
Or using options
GitSharp.Commands.Clone(new CloneCommand() { Source="git://github.com/henon/GitSharp.git", GitDirectory="path/to/local/copy", Quiet=false, Bare=true});
