RShell

Rust Shell. This is an attempt to create a simple shell in Rust, because why not.

My starting point is this article which is excellent. I will start with the final form of a shell given in the article and try to reformat it:

• Make it more easy to extend
• Make it a lib

I can also add basic features:

• History
• customizable prompt
• Colours ?

Later, I can even make something useful out of it. For example, I could make it so that it is configurable via a config file. I could make it the default terminal via ssh for some user and make it so the terminal opens directly in a docker container, or chrooted or smthing, as a basic form of honeypot.

Done

• A basic history system. Writes to ~/history.rshell
• Tests for this history system

Todo

• Add a function that gets the path of the history file, rather than copying it every time
• Other tests for the rest of the features
• Add a builtin history command
• Add a builtin ! like in bash
• Get some sleep
• Order the file (modules...)
