.. _user_interface:

============================
Configure the user interface
============================

You can build several user interfaces into the resulting Docker image.
This is controlled with various :ref:`configuration files <config-files>`.


JupyterLab
==========

You do not need any extra configuration in order to allow the use
of the JupyterLab interface. You can launch JupyterLab from within a user
session by opening the Jupyter Notebook and appending ``/lab`` to the end of the URL
like so:

.. code-block:: none

   http(s)://<server:port>/lab

To switch back to the classic notebook, add ``/tree`` to the URL like so:

.. code-block:: none

   http(s)://<server:port>/tree

For example, the following Binder URL will open the
`pyTudes repository <https://github.com/norvig/pytudes>`_
and begin a JupyterLab session in the ``ipynb`` folder:

https://mybinder.org/v2/gh/norvig/pytudes/master?urlpath=lab/tree/ipynb

The ``/tree/ipynb`` above is how JupyterLab directs you to a specific file
or folder.

To learn more about URLs in JupyterLab and Jupyter Notebook, visit
`starting JupyterLab <http://jupyterlab.readthedocs.io/en/latest/getting_started/starting.html>`_.


nteract
=======

`nteract is a notebook interface <https://nteract.io/>`_ built with React.
It is similar to a more feature-filled version of the traditional
Jupyter Notebook interface.

nteract comes pre-installed in any session that has been built from
a Python repository.

You can launch nteract from within a user
session by replacing ``/tree`` with ``/nteract`` at the end of a notebook
server's URL like so:

.. code-block:: none

   http(s)://<server:port>/nteract

For example, the following Binder URL will open the
`pyTudes repository <https://github.com/norvig/pytudes>`_
and begin an nteract session in the ``ipynb`` folder:

https://mybinder.org/v2/gh/norvig/pytudes/master?urlpath=nteract/tree/ipynb

The ``/tree/ipynb`` above is how nteract directs you to a specific file
or folder.

To learn more about nteract, visit `the nteract website <https://nteract.io/about>`_.


RStudio
=======

The RStudio user interface is automatically enabled if a configuration file for
R is detected (i.e. an R version specified in ``runtime.txt``). If this is detected,
RStudio will be accessible by appending ``/rstudio`` to the URL, like so:

.. code-block:: none

   http(s)://<server:port>/rstudio

For example, the following Binder link will open an RStudio session in
the `R demo repository <https://github.com/binder-examples/r>`_.

http://mybinder.org/v2/gh/binder-examples/r/master?urlpath=rstudio


Shiny
=====

`Shiny lets you create interactive visualizaions with R <https://shiny.rstudio.com/>`_.
Shiny is automatically enabled if a configuration file for
R is detected (i.e. an R version specified in ``runtime.txt``). If
this is detected, Shiny will be accessible by appending
``/shiny/<folder-w-shiny-files>`` to the URL, like so:

.. code-block:: none

   http(s)://<server:port>/shiny/bus-dashboard

This assumes that a folder called ``bus-dashboard`` exists in the root
of the repository, and that it contains all of the files needed to run
a Shiny app.

For example, the following Binder link will open a Shiny session in
the `R demo repository <https://github.com/binder-examples/r>`_.

http://mybinder.org/v2/gh/binder-examples/r/master?urlpath=shiny/bus-dashboard/


Stencila
========

The Stencila user interface is automatically enabled if a Stencila document (i.e.
a file ``manifest.xml``) is detected. Stencila will be accessible by appending
``/stencila`` to the URL, like so:

.. code-block:: none

   http(s)://<server:port>/stencila

The editor will open the Stencila document corresponding to the last ``manifest.xml``
found in the file tree. If you want to open a different document, you can configure
the path in the URL parameter ``archive``:

.. code-block:: none

   http(s)://<server:port>/stencila/?archive=other-dir
