## Environment variables
export XDG_CACHE_HOME=$HOME/.cache
export XDG_CONFIG_HOME=$HOME/.config

export PYTHON_BASIC_REPL=1 # use readline (Python >=3.13 defaults to its own REPL which has no vi keybindings)

# If we'd extend the PATH with PATH=$PATH:extra the PATH would become longer with each subshell.
# In ZSH PATH is tied to the $path array. We force that array to have unique values:
typeset -U path PATH
# Now we can append PATH entries with path+=... without the PATH growing in each subshell.

## Completion
