An extension for IPython that help to use Fortran in your interactive session.

Project description

Latest PyPI version Number of PyPI downloads

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

or directly from the repository using the %install_ext magic command:

In[1]: %install_ext https://raw.github.com/mgaitan/fortran_magic/master/fortranmagic.py

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 f1 is already available:

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

See the documentation for details.
