Installation
------------

Using Pip
~~~~~~~~~

If you have pip installed:

::

    $ pip install nbdiff

From Source
~~~~~~~~~~~

1. Download the code from this repository
2. Run ``python setup.py develop``

Configure Git/Mercurial
~~~~~~~~~~~~~~~~~~~~~~~

*Configuring nbmerge to work with your version control system can be helpful but is not required.*

NBMerge is compatible with Mercurial out of the box by running ``hg merge --tool=nbmerge <branch>``.

Git, however, needs to be configured by adding the following to your ``.gitconfig`` file:

::

    [mergetool "nbmerge"]                                                           
      cmd = nbmerge $LOCAL $BASE $REMOTE $MERGED

Alternatively, you can run the following command to add this configuration automatically:

::

    $ git config --global mergetool.nbmerge.cmd = "nbmerge \$LOCAL \$BASE \$REMOTE \$MERGED"

You can then run ``nbmerge`` from git like so:

::

    $ git mergetool --tool=nbmerge


Usage
-----

NBDiff
~~~~~~

NBDiff launches a server at ``localhost:5000`` and allows you to view a simple
2-pane diff of two notebook files.

::

    usage: nbdiff [-h] [before after]

    Produce a diffed IPython Notebook from before and after notebooks. If no
    arguments are given, nbdiff looks for modified notebook files in the version
    control system. The resulting diff is presented to the user in the browser at
    http://localhost:5000.

    positional arguments:
      before      The notebook to diff against.
      after       The notebook to compare `before` to.

    optional arguments:
      -h, --help  show this help message and exit


NBMerge
~~~~~~~

nbmerge launches

::


    usage: nbmerge [-h] [local base remote [result]]

    nbmerge is a tool for resolving merge conflicts in IPython Notebook files. If
    no arguments are given, nbmerge attempts to find the conflicting file in the
    version control system. Positional arguments are available for integration
    with version control systems such as Git and Mercurial.

    Once nbmerge is run, the UI can be accessed at http://localhost:5000

    positional arguments:
      notebook

    optional arguments:
      -h, --help  show this help message and exit


Developing
----------

Run the Python tests
~~~~~~~~~~~~~~~~~~~~

To get all of the dependencies necessary to test nbdiff, run:

::

    $ pip install -r requirements-dev.txt


To run the python tests, run the following command:

::

    $ python setup.py nosetests

NBDiff adheres to `PEP-8 <http://www.python.org/dev/peps/pep-0008/>`__. To check the code
against PEP-8, use ``flake8`` like so:

::

    $ flake8 tests nbdiff


To check Python test coverage, install ``coverage`` and run the tests with the ``--with-coverage`` option.

::

    $ pip install coverage
    $ python setup.py nosetests --with-coverage


Run the JavaScript tests
~~~~~~~~~~~~~~~~~~~~~~~~

First, install `node <http://nodejs.org/>`__ and npm.

Second, install the JavaScript dependencies using ``npm``.

::

    $ npm install

Finally, run the tests with ``grunt``. You should output similar to the following.
Note that ``grunt`` will not only run the tests, but check for common style problems with ``jshint``.

::

    $ grunt

    Running "qunit:files" (qunit) task
    Testing src/test/index.html ...OK
    >> 14 assertions passed (21ms)

    Done, without errors.
