isfepy

#!/usr/bin/python
"""
Python shell for SfePy.

   This is just a normal Python shell (IPython shell if you have the
   IPython package installed),  that executes the following commands
   for the user:

       >>> from sfepy.base.base import *
       >>> from sfepy.fem import *
       >>> from sfepy.applications import solve_pde
       >>> from sfepy.postprocess import Viewer

   So starting 'isfepy' is roughly (*) equivalent to starting Python (or
   IPython) and executing the above commands by hand. It is intended for easy
   and quick experimentation with SfePy.

   (*) Advantages of using isfepy instead of IPython directly are:
       - all SfePy messages are logged into ~/.sfepy/isfepy.log;
       - it is possible to silence the messages printed on screen.

   COMMAND LINE OPTIONS
   --------------------

   -c CONSOLE, --console=CONSOLE

     Use the specified Python or IPython shell as console backend instead
     of the default one (IPython if present or Python otherwise), e.g.:

        isfepy -c python

   -q, --quiet

     Print only Python's and SfePy's versions to stdout at startup.

   -s, --silent

     Silence the messages printed to screen.

   -- IPython's options

     Additionally you can pass command line options directly to IPython
     interpreter (standard Python shell is not supported).  However you
     need to add '--' separator between two types of options. To run
     SfePy without startup banner and colors, for example, issue:

        isfepy -q -- -colors NoColor
        isfepy -q -- --colors NoColor (for ipython >= 0.11)

     For non-blocking matplotlib plots in ipython >= 0.11 use:

        isfepy -- --pylab=wx
