crysh shell

A Linux shell written in Crystal.

Installation

Crysh needs to be built from source for now. To do that, you must install Crystal.

1. Clone this repo: git clone https://github.com/Sevensidedmarble/crysh.git && cd crysh

2. Install dependencies: run: shards install (shards might be a seperate package in your package manager. Make sure you have it. You could try crystal deps install as well.)

3. Build: crystal build src/crysh.cr --release.

4. You can run crysh right from this directory with ./crysh

5. You can now symlink to your bin folder (make sure /usr/local/bin is on your path, or use /usr/bin):

• In bash/zsh: sudo ln -sf $(pwd)/crysh /usr/local/bin/crysh

• In fish: sudo ln -sf (pwd)/crysh /usr/local/bin/crysh

Usage

Follow the instructions above. Crysh can be used like any other unix shell. It does not aim to be 100% POSIX complete, but it should be as POSIX complete as fish when 1.0 is released.

Development

I've collected some very helpful resources about programming shells in the wiki, available here.
