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](https://www.erlang.org/doc/apps/stdlib/io_protocol.html) and doesn't conflict with live blocks.
