Crush is an attempt to make a traditional command line shell that is also a modern programming language. It has the features one would expect from a modern programming language like a type system, closures and lexical scoping, but with a syntax geared toward both batch and interactive shell usage.

• The overview gives a detailed overview of the features of Crush.
• The syntax documentation contains more a detailed description of the Crush syntax than what fits into the overview document.
• The configuration documentation describes how to configure Crush.
• The hacking documentation will eventually give you enough information about the inner workings of Crush to start hacking yourself.

• Install Brew.
• Install openssl brew install openssl
• Install protobuf brew install protobuf
• Install git xcode-select --install

• Update apt index apt update
• Install dependencies apt install build-essential git curl pkg-config libssl-dev libdbus-1-dev libsystemd-dev

Install Rust

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Add it to your path

PATH=$PATH:$HOME/.cargo/bin

clone this repository,

git clone https://github.com/liljencrantz/crush.git

and run

cd crush && cargo build --release && cargo install --path .

and you should have a working binary to try out in ~/.cargo/bin. That directory should already be in your path, so just write crush to run the shell.

Have fun!
