startup.py

"""
Trey's Python startup file

This file adds keyboard shortcuts to pyrepl (3.13+).
It also customizes REPL syntax highlighting (3.14+).

To use this file:

Put this in your ~/.zshenv, ~/.zshrc, ~/.bashrc, etc.:
export PYTHONSTARTUP=$HOME/.startup.py

Run this:
mkdir -p $HOME/.pyhacks
python -m pip install pyrepl-hacks --target=$HOME/.pyhacks
