Compile and import symbols from a cell with Fortran code, using f2py.

The contents of the cell are written to a `.f90` file in the
directory `IPYTHONDIR/fortran` using a filename with the hash of the
code. This file is then compiled. The resulting module
is imported and all of its symbols are injected into the user's
namespace.

Install
=======

You can install or upgrade via pip

pip install -U fortran-magic


Basic usage
===========

Once it's installed, you can load it with ``%load_ext fortranmagic``.
Then put your Fortran code in a cell started with the cell magic ``%%fortran``. For example::


In[2]: %load_ext fortranmagic

In[3]: %%fortran

subroutine f1(x, y, z)
real, intent(in) :: x,y
real, intent(out) :: z

z = sin(x+y)

end subroutine f1


Every symbol is automatically imported. So the subroutine `f1` is already available in your python session as a function::

In[4]: f1(1.0, 2.1415)
Out[4]: 9.26574066397734e-05


See the documentation_ for further details.

0.4.2 / 2013-10-08
------------------

- Implement the ``--extra`` option (Thanks to `Denis Vasilyev`_ for the help)
- Include ``%%fortran``'s args in the hashing, so the same cell are
recompiled with the same code but different arguments

0.3 / 2013-10-03
------------------

- Added ``%fortran_config`` to set and persist default arguments
for ``%%fortran``

------------------

- Packaged and registered in pypi
- Starting a version's changelog

0.2 / 2013-09-19
----------------

- Fortran highlighting in a ``%%fortran`` cell
- Works (or it should) in any platform (linux/windows/osx)
and with py3 (thanks to `Bradley Froehle`_)
- Many f2py's arguments exposed as magic arguments
- Verbosity handling
- Improved documentation
