Getting started. ##

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

bash
npm install nodegit

If you receive errors about libstdc++, which are commonly experienced when
building on Travis-CI, you can fix this by upgrading to the latest
libstdc++-4.9.

In Ubuntu:

sh
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install libstdc++-4.9-dev

In Travis:

yaml
addons:
  apt:
    sources:
      - ubuntu-toolchain-r-test
    packages:
      - libstdc++-4.9-dev

In CircleCI:

yaml
  dependencies:
    pre:
      - sudo add-apt-repository -y ppa:ubuntu-toolchain-r/test
      - sudo apt-get update
      - sudo apt-get install -y libstdc++-4.9-dev

If you receive errors about *lifecycleScripts* preinstall/install you probably miss *libssl-dev* In Ubuntu:

sudo apt-get install libssl-dev

You will need the following libraries installed on your linux machine:
- libpcre
- libpcreposix
- libkrb5
- libk5crypto
- libcom_err

When building locally, you will also need development packages for kerberos and pcre, so both of these utilities must be present on your machine:
- pcre-config
- krb5-config

If you are still encountering problems while installing, you should try the
Building from source
instructions.

API examples. ##

Cloning a repository and reading a file: ###

javascript
var Git = require("nodegit");

// Clone a given repository into the `./tmp` folder.
Git.Clone("https://github.com/nodegit/nodegit", "./tmp")
  // Look up this known commit.
  .then(function(repo) {
    // Use a known commit sha from this repository.
    return repo.getCommit("59b20b8d5c6ff8d09518454d4dd8b7b30f095ab5");
  })
  // Look up a specific file within that commit.
  .then(function(commit) {
    return commit.getEntry("README.md");
  })
  // Get the blob contents from the file.
  .then(function(entry) {
    // Patch the blob to contain a reference to the entry.
    return entry.getBlob().then(function(blob) {
      blob.entry = entry;
      return blob;
    });
  })
  // Display information about the blob.
  .then(function(blob) {
    // Show the path, sha, and filesize in bytes.
    console.log(blob.entry.path() + blob.entry.sha() + blob.rawsize() + "b");

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

    // Show the entire file.
    console.log(String(blob));
  })
  .catch(function(err) { console.log(err); });

Emulating git log: ###

javascript
var Git = require("nodegit");

// Open the repository directory.
Git.Repository.open("tmp")
  // Open the master branch.
  .then(function(repo) {
    return repo.getMasterCommit();
  })
  // Display information about commits on master.
  .then(function(firstCommitOnMaster) {
    // Create a new history event emitter.
    var history = firstCommitOnMaster.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.

bash
npm test
