powerconf

Powerful configuration tools for numerical simulation.

powerconf allows you to write configuration files for things like physics simulations with support for variable interpolation and expression evaluation. Consider a simulation will solve some partial differential equation on a 2-dimensional Cartesian grid. Perhaps the simulation itself requires us to set the min and max range and the number of points to use along each axis. A simple YAML configuration for the simulation might look something like this

grid:
    x:
        min: 0 cm
        max: 1.5 cm
        N: 151
    y:
        min: 0 cm
        max: 1.0 cm
        N: 101

This is fine, but it might be useful to specify the resolution to use instead of the number of points. With powerconf, we can write a configuration file that looks like this

grid:
    resolution: 1 um
    x:
        min: 0 cm
        max: 1.5 cm
        N: $( (${max} - ${min})/${../resolution} + 1)
    y:
        min: 0 cm
        max: 1.0 cm
        N: $( (${max} - ${min})/${../resolution} + 1)

In this example, we give a resolution to use for both x and y directions and then calculate the number of points to use with an expression. Note the relative paths to configuration parameters used in the expressions. powerconf uses the fspathtree module to provide filesystem-like access to elements in a nested dict.
