Library for parsing and writing Nintendo EventFlow binary files

evfl is able to parse and rewrite every single event flow found in Breath of the Wild and Tears of the Kingdom, both flowcharts and timelines. It also reads and writes version 4 event flows, as used by the Ocarina of Time remake.

Usage

import evfl

flow = evfl.EventFlow()
with open('Animal_Master.bfevfl', 'rb') as file:
    flow.read(file.read())

flowchart = flow.flowchart
# Real documentation is nonexistent at the moment. I'm sorry.

with open('Animal_Master_Modified.bfevfl', 'wb') as modified_file:
    flow.write(modified_file)

Tests

Unit and integration tests can be executed by running python3 -m unittest discover.
