A package for communicating with FORM

Project description

PyPI version Python versions Build Status Coverage Documentation Status DOI

This package provides a mechanism to embed FORM [1] [2] [3] programs in Python code. The basic idea of the implementation is the same as FormLink [4]: it utilizes unnamed pipes between FORM and an external program [5], Python in this case. It is expected to work on Unix-like systems.

Installation

$ pip install python-form

or directly from GitHub for the latest development version:

$ pip install git+https://github.com/tueda/python-form.git

See also the documentation for pip install.

Example

import form

with form.open() as f:
    f.write('''
        AutoDeclare Vector p;
        Local F = g_(0,p1,...,p6);
        trace4,0;
        .sort
    ''')
    print(f.read('F'))

Licence

python-form is distributed under the MIT licence. See the LICENCE file.

Note that FORM itself adopts the GPL version 3. A program/package using FORM via python-form could be considered as an aggregate (at your own risk) or a combined work affected by the GPL.
