# Rainbow-output helpers built on lolcat = Debian's busyloop Ruby build at

# /usr/games/lolcat (upstream github.com/busyloop/lolcat; 24-bit truecolor).
|
|
# It auto-detects a tty, so use -f/--force-color to colorize mid-pipeline.
|
|
# This lolcat is truecolor and auto-detects a tty: it colorizes when writing
|
|
# straight to the terminal, but passes text through UNcolored when piped onward,
|
|
# so use -f/--force to colorize in the middle of a pipeline.
|
|
|
|
# Debian ships lolcat in /usr/games; make sure it's reachable in any shell.

|
|
# colors/columns -- e.g. use `lol ls -C` to keep ls in columns.)

|
|
# and buffers streaming output. Use it for a burst of plain command output,
|
|
# then rainbow_off. Does not affect stderr.
