Created December 16, 2022 05:21
Convert Lift Gamma Gain coefficients from PostProcessing V2 to URP 12.x
// URP has a tool to convert postprocessing volumes but it doesn't transform the coefficients so the visuals won't look the same
// This does the transformation to make them match.

Python SequenceMatcher for finding a similarly-named file

Here's a cute example of using Python's builtin difflib support to find a file with the closest matching name

Python Metaprogramming: An example of how to use Abstract Syntax Trees (ast module) in Python to turn bare expressions (not bound to any target variable names) in an end-user configuration file into elements of a list.
"""
This file is made by the user, to set up model components for a Markov Chain
Monte Carlo galaxy simulator.
For simplicity, I didn't want to force the user to bind everything to variables,
or follow some particular naming scheme, or remember to add them to a list, etc.
YAML or such seemed like overkill, since python keyword arguments already make it
pretty human-readable
