GAMMA Command API

This is an attempt to make it easier to execute Gamma commands by offering automatically parsed Python functions. Thus, instead of executing the command via shell:

offset_fit offs ccp off.par coffs - 0.15 3 0 > offset_fit.log

one can wrap it in a Python script:

import os
from pyroSAR.gamma.api import isp

workdir = '/data/gamma_workdir'

parameters = {'offs': os.path.join(workdir, 'offs'),
              'ccp': os.path.join(workdir, 'ccp'),
              'OFF_par': os.path.join(workdir, 'off.par'),
              'coffs': os.path.join(workdir, 'coffs'),
              'thres': 0.15,
              'npoly': 3,
              'interact_flag': 0,
              'logpath': workdir}

isp.offset_fit(**parameters)

A file offset_fit.log containing the output of the command is written in both cases. Any parameters, which should not be written and need to be set to - in the shell can be omitted in the Python call since all optional parameters of the functions are already defined with '-' as a default. The documentation can be called like with any Python function:

from pyroSAR.gamma.api import isp
help(isp.offset_fit)

API Demo

This is a demonstration of an output script as generated automatically by function ~pyroSAR.gamma.parser.parse_module for the Gamma module ISP. Within each function, the command name and all parameters are passed to function ~pyroSAR.gamma.process, which converts all input to :pystr and then calls the command via the subprocess module.
