# Blake's bashrc

# ZSH supremacy

# 99.99% of this is the default bashrc for manjaro, I just liked it so I took
# it, and I don't use bash enough to care. The main job of this is to load my
# basic shell configuration, which works in any POSIX shell.

# If not running interactively, don't do anything
[[ $- != *i* ]] && return

# Just in case
export SHELL_CONFIG_DIR="${SHELL_CONFIG_DIR:-"${XDG_CONFIG_HOME:-"$HOME/.config"}/shell"}"
