# Shorthand for newline
export n=$'\n'
# Shorthand for two newlines
export n2=$'\n\n'
# Shorthand for newline followed by tab
export nt=$'\n\t'
# Shorthand for bold face

## Notes for developers:
##  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# TPUT exudes a B( character secretly during setting Bold. This screws up ponysay's character count!
# For this reason we gotta use the actual codes.
#export bold=$(tput bold)
#export normal=$(tput sgr0)
#function bold(){
#    printf "\033[1m$1\033[0m"
#    #$(tput bold; echo -n "$1"; tput sgr0)
#}
# In my testing, the runtime for $(bold "test") is 20x slower than the shorthands above!
