Owl is a toolkit for writing command-line user interfaces in Elixir.

It provides a convenient interface for

• colorizing text using tags
• input control with validations and casting to various data types
• select/multiselect controls, inspired by AUR package managers
• tables
• editing text in ELIXIR_EDITOR
• wrapping multiline colorized data into ASCII boxes
• printing palette colors
• progress bars and spinners, multiple bars/spinners at the same time are supported as well
• live-updating of multiline blocks
• working with virtual device which partially implements The Erlang I/O Protocol and doesn't conflict with live blocks.

Demo

The code can be found in examples directory.
