Generate the command lines needed to loop over various command line parameters

Jobrunner

This program is used to sweep through a series of parameters when calling a program. For example

jobrunner.py "myprog -size {20,40} -age {30,50,55}"

Will print the following, which can be put in a script etc.:

myprog -size 20 -age 30
myprog -size 20 -age 50
myprog -size 20 -age 55
myprog -size 40 -age 30
myprog -size 40 -age 50
myprog -size 40 -age 55

Note that we pass the command line as a quoted string to prevent interferance by the shell. The ordering of the output command lines is arbitrary.

Typically myprog will append results to a file.

An additional syntax element is also supported. If multiple files need to be loaded relating to the same experimental unit, then we can do stem expansion:

jobrunner.py "myprog -auxfile {p: P01, P02}_auxfile.csv -datafile data{p:}.txt -size {20,40}"

will generate:

myprog -auxfile P01_auxfile.csv -datafile dataP01.txt -size 20
myprog -auxfile P02_auxfile.csv -datafile dataP02.txt -size 20
myprog -auxfile P01_auxfile.csv -datafile dataP01.txt -size 40
myprog -auxfile P02_auxfile.csv -datafile dataP02.txt -size 40
