#! /bin/sh

# outputs a code snippet to be added to the setup script for a given program's config directory
# it must be run in dots directory
# it won't work completely for most config files but it gets rid of some typing of boilerplate
# don't forget to also add "setup_whatever" to the setup_all() function in the setup script

# e.g. ./template.sh foot ~/.config/foot
# will output a snippet that would  symlink every file in $DOTS/foot under $HOME/.config/foot
# any occurrence "$HOME" expansion (i.e. /home/your-username) in $2 is replaced with '$HOME'
# if the second argument is omitted, $HOME/.config/"$1" is selected
