quick-color

Color terminal output from stdout. That is all.

echo "hello world" | quick-color '#0a0'

I had a hard time finding a binary that does this. Someone point it out if it exists.

The main goal is to produce colored terminal output for tailing log levels in a way that doesn't use hard-to-understand escape sequences.

Installation

See releases.
