Building and Installing.

Minimum dependencies:

• Python 2
• CMake >= 2.8

npm install nodegit

Building manually:

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

# Install the template engine, run the code generation script, and install.
npm install ejs && npm run codegen && npm install

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

Installing dependencies:

OS X

Using Brew:

brew install cmake libzip

Linux

Using APT in Ubuntu:

sudo apt-get install cmake libzip-dev build-essential

Using Pacman in Arch Linux:

sudo pacman -S cmake libzip base-devel

Windows

• Download and install CMake.
• 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").Repo.clone;

// Clone a given repository into a specific folder.
clone("https://github.com/nodegit/nodegit", "tmp", null, function(err, repo) {
  if (err) {
    throw err;
  }

  // Use a known commit sha from this repository.
  var sha = "59b20b8d5c6ff8d09518454d4dd8b7b30f095ab5";

  // Look up this known commit.
  repo.getCommit(sha, function(err, commit) {
    if (err) {
      throw error;
    }

    // Look up a specific file within that commit.
    commit.getEntry("README.md", function(err, entry) {
      if (err) {
        throw error;
      }

      // Get the blob contents from the file.
      entry.getBlob(function(err, blob) {
        if (err) {
          throw err;
        }

        // 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").Repo.open;

// Open the repository directory.
open("tmp", function(err, repo) {
  if (err) {
    throw err;
  }

  // Open the master branch.
  repo.getMaster(function(err, branch) {
    if (err) {
      throw err;
    }

    // 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.
