GEMPAK/Python interface
- Subject: GEMPAK/Python interface
- Date: Fri, 27 Feb 2004 18:58:35 -0500
My wife uses the gemlib functions in her work as a student to access
grid files. In order to do this, she, of course, uses FORTRAN.
However, she wanted to use some functionality of the Python
(http://www.python.org) language as well in these programs, but there
really wasn't an efficient/easy way to do this. If you aren't familiar
with Python, it is a very simple to use, but very powerful scripting
language (similar to Perl, but not as ugly :) ). After doing some work
on this and working with the developer of F2Py
(http://cens.ioc.ee/projects/f2py2e/) to iron out some problems, I was
able to successfully wrap several gd functions and create a very easy
to use Python interface to grid files with very little work. I don't,
however, have the GEMPAK expertise to do a complete interface to all of
GEMPAK's functionality, and thought that I would present my work to you
in case you wanted to continue this work.
The basic process of creating Python interfaces is:
- Add f2py directives to FORTRAN files to guide f2py in creating
interface files
- Run f2py on the FORTRAN files to create the Python interface
- Write Python class wrappers around GEMPAK functions to give them
a more object oriented presentation
I've included a tar file of the the gd*.f files, as well as inbdta.f, a
small build script, and a Python module that wraps the gd functions in
a "Pythonic" way (see the comments at the top of gempak.py for examples
of it's usage). If you have any questions, please let me know.
