Getting started.

NodeGit will work on most systems out-of-the-box without any native dependencies.

npm install nodegit

If you encounter problems while installing, you should try the Building from source instructions below.

Building from source.

Minimum dependencies:

• Python 2

If you wish to help contribute to nodegit it is useful to build locally.

# Fetch this project.
git clone git://github.com/tbranyen/nodegit.git

# Enter the repository.
cd nodegit

# Installs the template engine, run the code generation script, and build.
npm install

If you encounter errors, you most likely have not configured the dependencies correctly.

Installing dependencies:

Mac OS X

• Install XCode Command Line Tools

Linux

Using APT in Ubuntu:

sudo apt-get install build-essential

Using Pacman in Arch Linux:

sudo pacman -S base-devel

Windows

• Download and install Python.
• Download and install VS Express.

You may have to add a build flag to the installation process to successfully install. Try first without, if the build fails, try again with the flag.

Allegedly the order in which you install Visual Studio could trigger this error.

npm install nodegit --msvs_version=2013
# Or whatever version you've installed.

API examples.

Cloning a repository and reading a file:

var clone = require("nodegit").Repository.clone;

// Clone a given repository into a specific folder.
clone("https://github.com/nodegit/nodegit", "tmp", null).then(function(repo) {
  // Use a known commit sha from this repository.
  var sha = "59b20b8d5c6ff8d09518454d4dd8b7b30f095ab5";

  // Look up this known commit.
  repo.getCommit(sha).then(function(commit) {
    // Look up a specific file within that commit.
    commit.getEntry("README.md").then(function(entry) {
      // Get the blob contents from the file.
      entry.getBlob().then(function(blob) {
        // Show the name, sha, and filesize in byes.
        console.log(entry.name() + entry.sha() + blob.size() + "b");

        // Show a spacer.
        console.log(Array(72).join("=") + "\n\n");

        // Show the entire file.
        console.log(String(blob));
      });
    });
  });
});

Emulating git log:

var open = require("nodegit").Repository.open;

// Open the repository directory.
open("tmp").then(function(repo) {
  // Open the master branch.
  repo.getMaster().then(function(branch) {
    // Create a new history event emitter.
    var history = branch.history();

    // Create a counter to only show up to 9 entries.
    var count = 0;

    // Listen for commit events from the history.
    history.on("commit", function(commit) {
      // Disregard commits past 9.
      if (++count >= 9) {
        return;
      }

      // Show the commit sha.
      console.log("commit " + commit.sha());

      // Store the author object.
      var author = commit.author();

      // Display author information.
      console.log("Author:\t" + author.name() + " <", author.email() + ">");

      // Show the commit date.
      console.log("Date:\t" + commit.date());

      // Give some space and show the message.
      console.log("\n    " + commit.message());
    });

    // Start emitting events.
    history.start();
  });
});

Unit tests.

You will need to build locally before running the tests. See above.

npm test
