random-python

Generate random Python from a corpus of examples

• The function give_me_random_code generates a new code example from a corpus
• The class RandomCodeSource will continually generate new code samples from a corpus

The code was inspired by Wave Function Collapse by Maxim Gumin to exchange subsets of examples from the corpus in a random fashion to arrive at new code blocks

Features

Things that Work:

• Running the default script on a small custom example
• Running the example script on an a big codebase
• Check variable names are in scope
• Tests that verify important functions

Things that are planned to work in the future:

• Exchange elements with elements of the exact same type, so the logic is likely useful
• Exchange similar elements (e.g. import/import from, replacing an integer with a function that returns an integer)
