"""
Adds a custom 'agbl' (AGB Loop end) chunk to looped .wav files.
This chunk specifies the exact loop-end point to handle the off-by-one error
in the original game, where the loop-end should be one sample earlier than
the total number of samples in the file.

Update new map constants
# This script will apply the same changes to your project as this PR: https://github.com/pret/pokeemerald/pull/1755/files
# You can run this before or after merging with upstream pret, so that your project's custom code and data are updated appropriately.
# To run this script:
# - Place this file in the root of your project. For example, pokeemearld/map_constants_update.py
# - Run "python map_constants_update.py"
import re
import glob
# 1. In map.json files, convert "dest_warp_id" to string value instead of integer. 127 becomes "WARP_ID_DYNAMIC". 126 becomes "WARP_ID_SECRET_BASE."

Region map generator
# This is a hacky thrown-together script that procedurally
# generates Gen-3 Pokemon region map images. I intend to build
# an online tool to facilitate this, but this is the first
# proof of concept.
#
# Requires the opensimplix, Pillow, and scikit-learn:
# pip install opensimplex
# pip install Pillow
# pip install -U scikit-learn

# pokemap2json.py
# This script will process a pokeemerald project and generate the wild encounters JSON data for it.
# It creates:
# src/data/wild_encounters.json
#
# In order to convert your project's existing data from src/data/wild_encounters.h:
# 1. Merge pret/master.
# 2. Run wildencounters2json.py on your project.
# Example: "python wildencounters2json.py path/to/my/project"
# 3. Commit the src/data/wild_encounters.json file it creates.
# This script will convert some map json fields from integers to strings.
# Place this script in data/maps directory, and run it.
