A list of various projects I've worked on in no particular order.
gitwalk (npm package)
Manipulating multiple git repositories at the same time.
catpix (Ruby gem)
Printing images in the terminal using the xterm extended colour palette.
scriptster (Ruby gem)
A small and simple gem to help with scripting in Ruby. It only does two things: running shell commands and logging what happened.
tco (Ruby gem)
A Ruby library and command-line app that simplifies working with colours in the terminal. Pick different colours using RGB, not escape sequences.
