Hilbish

Hilbish is an extensible shell designed to be highly customizable. It is configured in Lua and provides a good range of features. It aims to be easy to use for anyone but powerful enough for those who need it. The motivation for choosing Lua was that it's simpler and better to use than an old shell script. It's fine for basic interactive shell uses, but that's the only place Hilbish has shell script; everything else is Lua and aims to be infinitely configurable. Hilbish is configured and scripted in the Lua programming language. This removes all the old, ugly things about Shell script and introduces everything good about Lua, including other languages (Fennel, Lua derivatives). Hilbish provides the user with proper menus for completions and history usage. Want to see your previous commands? Hit Ctrl-R. Hilbish offers a bunch of features to make your interactive shell experience rich. Things like syntax highlighting and hinting available via the Lua API.
