Currently, ``nbconvert`` is provided as a command line tool, run as a script
using IPython. In the future, a direct export capability from within the

IPython Notebook web app is planned.
The command-line syntax to run the ``nbconvert`` script is::
$ ipython nbconvert --format=FORMAT notebook.ipynb
$ ipython nbconvert --to FORMAT notebook.ipynb
This will convert the IPython document file ``notebook.ipynb`` into the output
format given by the ``FORMAT`` string.

The currently supported export formats are the following:
IPython provides a few templates for some output formats, and these can be
specified via an additional ``--template`` argument.
* HTML:
The currently supported export formats are:
- **full_html**:
Standard HTML
* ``--to html``
- **simple_html**:
Simplified HTML
- ``--template full`` (default)
A full static HTML render of the notebook.
This looks very similar to the interactive view.
- **reveal**:
HTML slideshow presentation for use with the ``reveal.js`` package
- ``--template basic``
Simplified HTML, useful for embedding in webpages, blogs, etc.
This excludes HTML headers.
* PDF:
* ``--to latex``
Latex export. This generates ``NOTEBOOK_NAME.tex`` file,
ready for export. You can automatically run latex on it to generate a PDF
by adding ``--post PDF``.
- ``--template article`` (default)
Latex article, derived from Sphinx's howto template.
- **sphinx_howto**:
The format for Sphinx_ HOWTOs; similar to an ``article`` in LaTeX
- ``--template book``
Latex book, derived from Sphinx's manual template.
- **sphinx_manual**:
The format for Sphinx_ manuals; similar to a ``book`` in LaTeX
- ``--template basic``
Very basic latex output - mainly meant as a starting point for custom templates.
- **latex**:
An article formatted completely using LaTeX
* ``--to slides``
* Markup:
This generates a Reveal.js HTML slideshow.
It must be served by an HTTP server. The easiest way to get this is to add
``--post serve`` on the command-line.
- **rst**:
reStructuredText_ markup
* ``--to markdown`` Simple markdown
- **markdown**:
Markdown_ markup
* ``--to rst`` reStructuredText

* ``--to python`` Convert a notebook to an executable Python script.
This is the simplest way to get a Python script out of a notebook.
If there were any magics in the notebook, this may only be executable from
an IPython session.
* Python:
Comments out all the non-Python code to produce a ``.py`` Python
script with just the code content. Currently the output includes IPython
magics, and so can be run with ``ipython``, after changing the extension
of the script to ``.ipy``.

Each of the options for PDF export produces as an intermediate step a LaTeX
``.tex`` file with the same basename as the notebook, as well as individual
files for each figure, and ``.text`` files with textual output from running
code cells.
To actually produce the final PDF file, run the following commands::
$ ipython nbconvert --format=latex notebook.ipynb
$ pdflatex notebook
This requires a local installation of LaTeX on your machine.
The output is a PDF file ``notebook.pdf``, also placed inside the
``nbconvert_build`` subdirectory.

Extracting standard Python files from notebooks
-----------------------------------------------
``.ipynb`` notebook document files are plain text files which store a
representation in JSON format of the contents of a notebook space. As such,
they are not valid ``.py`` Python scripts, and so can be neither imported
directly with ``import`` in Python, nor run directly as a standard Python
script (though both of these are possible with simple workarounds).
To extract the Python code from within a notebook document, the simplest
method is to use the ``File | Download as | Python (.py)`` menu item; the
resulting ``.py`` script will be downloaded to your browser's default
download location.
An alternative is to pass an argument to the IPython Notebook, from the moment
when it is originally started, specifying that whenever it saves an ``.ipynb``
notebook document, it should, at the same time, save the corresponding
``.py`` script. To do so, you can execute the following command::
$ ipython notebook --script
or you can set this option permanently in your configuration file with::
c = get_config()
c.NotebookManager.save_script=True
The result is that standard ``.py`` files are also now generated, which
can be ``%run``, imported from regular IPython sessions or other notebooks, or
executed at the command line, as usual. Since the raw code you have typed is
exported, you must avoid using syntax such as IPython magics and other
IPython-specific extensions to the language for the files to be able to be
successfully imported.
.. or you can change the script's extension to ``.ipy`` and run it with::
..
.. $ ipython script.ipy
In normal Python practice, the standard way to differentiate importable code
in a Python script from the "executable" part of a script is to use the
following idiom at the start of the executable part of the code::
if __name__ == '__main__'
# rest of the code...
Since all cells in the notebook are run as top-level code, you will need to
similarly protect *all* cells that you do not want executed when other scripts
try to import your notebook. A convenient shortand for this is to define
early on::
script = __name__ == '__main__'
Then in any cell that you need to protect, use::
if script:
# rest of the cell...

Notebook JSON file format
-------------------------
Notebook documents are JSON files with an ``.ipynb`` extension, formatted
as legibly as possible with minimal extra indentation and cell content broken
across lines to make them reasonably friendly to use in version-control
