node-git

This is a thin wrapper around the command-line git command for use inside node applications. It's used primarily by the wheat blogging system to enable a running node.JS server to read files out of a git repository as if they were local files.

Example usage

var sys = require('sys'),
    Git = require('git');
// Test it!
Git("/Users/tim/code/howtonode.org");
Git.exists("articles/control-flow-part-ii.markdown", function (err, tags) {
  if (err) { throw(err); }
  sys.p(tags);
});
Git.getTags(function (err, tags) {
  if (err) { throw(err); }
  Object.keys(tags).forEach(function (tag) {
    Git.readDir("articles", tags[tag], function (err, contents) {
      if (err) { throw(err); }
      contents.files.forEach(function (file) {
        file = Path.join("articles", file);
        Git.readFile(file, tags[tag], function (err, text) {
          if (err) { throw(err); }
          sys.error("tag: " + tag + " sha1: " + tags[tag] + " file: " + file + " length: " + text.length);
        });
      });
    });
  });
});

More example:

var sys = require('sys');
// Git("/Users/tim/git/howtonode.org.git");
Git("/Users/tim/Code/howtonode.org");
Git.log("articles/what-is-this.markdown", function (err, data) {
  if (err) throw err;
  sys.p(data);
  process.exit();
});
