Read, edit, and output parameters for scientific software.
Project description
Pyrameters
Pyrameters is a package for programmatically interacting with hierarchical parameter inputs for scientific software. It is currently targeted at the Deal.II PRM format.
Usage
This package can be installed from the PyPi package manager
pip install pyrameters
Using it is a matter of importing the pyrameters
module, and creating a PRM
object.
from pyrameters import PRM
with open('input.prm','r') as input:
prm = PRM(input.read())
if prm['Dimension'] == 2:
prm.set('/Model geometry/Hypercube/Length', 100)
else:
prm.get('/Model geometry/Hypercube/Length', 10)
print(prm)
An empty PRM
object can also be created without providing an input file.
from pyrameters import PRM
prm = PRM()
prm['Dimension'] = 3
prm['Output directory'] = 'results'
prm.add_subsection('Postprocess')
prm['Postprocess']['Output frequency'] = 10
prm.set('/Postprocess/Visualization/Format','vtu')
print(prm)
Which would output parameters to the terminal in valid PRM
format:
set Dimension = 3
set Output directory = resultssubsection Postprocess
set Output frequency = 10subsection Visuzliation
set Format = vtu
end
end
