Rash: The Reckless Racket Shell

Rash is a shell language, library, and REPL for Racket.

Use as a repl that is as convenient for pipelining programs as Bash is, but has all the power of Racket. Use as a scripting language with #lang rash. Embed in normal Racket files with (require rash), and mix freely with any other Racket language or library.

Rash is in active development, and is not stable as a language. But I use it as my default interactive shell on my laptop. It's far from complete, but I already like it much better than Bash. Give it a try.

Getting started

Prerequisites

Rash does work on windows, but it works better and is more useful on unix based systems.

To install, you will need a working instalation of racket v6.12.

Installation

You can either install with racket's built in package manager, raco, or install directly from github. If you have DrRacket installed, you can install rash with File -> Install Package.

via raco:

raco pkg install rash

git version:

git clone https://github.com/willghatch/racket-rash rash && cd rash/linea && raco pkg install && cd ../shell-pipeline && raco pkg install && cd ../rash && raco pkg install

OR

use raco pkg install --clone rash

Usage

Online documentation is here. After installation, local documentation can be accessed with raco docs rash.

Here's a quick demo video of Rash in action:

I gave a talk about Rash at RacketCon 2017. It's slightly out of date, but you can watch it here.

This repo also contains the shell-pipeline and linea packages. They mostly support Rash itself, so they live in the same repo.
