Gravelamps Module Handling

Following are functions that handle modules used within Gravelamps. This is largely an interface used for handling the module that will contain the lensing functions in an agnostic fashion

Written by Mick Wright 2022

Routines

get_lens_module: Retrieves module to be used for lensing functions
check_module: Ascertains the existence of given module
get_interpolator_model: Retrieves module to be used for interpolator functions

Functions

`get_lens_module`(config, args)	Retrieves module to be used for lensing functions
`check_module`(module_name)	Ascertains the existence of a given module
`get_interpolator_model`(config, args)	Retrieves module to be used for interpolator functions

Module Contents

gravelamps.core.module_handling.get_lens_module(config, args)

Retrieves module to be used for lensing functions

The module is specified by the user either as a full python path or as a submodule of gravelamps.lensing. If the module is not supplied at all, it defaults to gravelamps.lensing.interpolator.

Parameters:

configconfigparser.ConfigParser: Object containing settings from INI file
argsargparse.Namespace: Object containing commandline arguments to program

Returns:

lens_moduleModuleType: Module containing the lensing functions

gravelamps.core.module_handling.check_module(module_name)

Ascertains the existence of a given module

Parameters:

module_namestr: full python path of the module to be checked

Returns:

bool: Flag of whether the module exists or not

gravelamps.core.module_handling.get_interpolator_model(config, args)

Retrieves module to be used for interpolator functions

The model for the interpolator should be specified in the INI as either a complete python path or one of the submodules of gravelamps.lensing. Will return None if no module is specified

Parameters:

configconfigparser.ConfigParser: Object containing settings from the INI file
argsargparse.Namespace: Object containing commandline arguments to the program

Returns:

interpolator_modelstr: Full python path to the interpolator model module

Raises:

ModuleNotFoundError: If the full python path as determined by the function cannot be loaded as a module
