yaml_prop

Extended PyYAML loader and dumper for properties with physical units used in scientific computing.

This utility extends PyYAML with the following YAML tags:

• !array: Takes a yaml.SequenceNode and converts it into the array or tensor object of your preference with array_yaml_constructor(). The default array constructor is numpy.array.
• !numexpr: Leverages the numexpr library to evaluate numpy expressions from a YAML mapping node with an expr key and an optional alias key for resolving aliases within the expression.
• !lambda: Creates a Lambda expression via numexpr from a YAML mapping node with args, expr, and alias keys.

These basic utilities are then used to define physical properties with physical unit conversions handled by pintusing the UNITS registry:

• !constant: Creates a constant physical property represented by a ConstantProperty.
• !table: Creates a lookup table physical property based on an underlying scipy.interpolate.RegularGridInterpolator. See TableProperty.
• !function: Wraps around a Lambda object and performs unit conversions. Refer to FunctionProperty.

The basic utilities and physical properties are included in PropertyLoader and PropertyDumper.
