Building and installing

Dependencies

To install nodegit you need Node.js, python and cmake (>=2.8).

Easy install (Recommended)

This will install and configure everything you need to use nodegit.

$ npm run-script gen && npm install && npm test

Mac OS X/Linux/Unix

Install nodegit by cloning source from GitHub and running node install:

$ git clone git://github.com/tbranyen/nodegit.git
$ cd nodegit
$ npm run-script gen && npm install

Windows via Cygwin

nodegit has been compiled and tested to work with the setup required to build and run Node.js itself.

Instructions on compiling Node.js on a Windows platform can be found here: https://github.com/ry/node/wiki/Building-node.js-on-Cygwin-(Windows)

API Example Usage

Below are two examples. There are several more.

Git Log Emulation

var git = require('../'),
    path = require('path');

git.Repo.open(path.resolve(__dirname, '/tmp/repo/.git'), function(error, repo) {
  if (error) throw error;

  repo.getMaster(function(error, branch) {
    if (error) throw error;

    // History returns an event.
    var history = branch.history();

    // History emits 'commit' event for each commit in the branch's history
    history.on('commit', function(commit) {
      console.log('commit ' + commit.sha());
      console.log('Author:', commit.author().name() + ' <' + commit.author().email() + '>');
      console.log('Date:', commit.date());
      console.log('\n    ' + commit.message());
    });

    // Don't forget to call `start()`!
    history.start();
  });
});

Clone a repo and read a file

git.Repo.clone("https://github.com/nodegit/nodegit.git", path, null, function(error, repo) {
  if (error) throw error;

  repo.getCommit('59b20b8d5c6ff8d09518454d4dd8b7b30f095ab5', function(error, commit) {
    if (error) throw error;

    commit.getEntry('README.md', function(error, entry) {
      if (error) throw error;

      entry.getBlob(function(error, blob) {
        if (error) throw error;

        console.log(entry.name(), entry.sha(), blob.size() + 'b');
        console.log('========================================================\n\n');
        var firstTenLines = blob.toString().split('\n').slice(0, 10).join('\n');
        console.log(firstTenLines);
        console.log('...');
      });
    });
  });
});
