This project contains multiple implementations of UNIX shells. The goal of this project is to build a JIT-compiled shell, that allows the user to send complex data structures through the pipeline (as opposed to bash and other popular UNIX shells).
Well, most shells today are interpreters. The infamous bash, with all its limitations, remains king of shells. While most users are satisfied with bash, we wanted to push things a little further. A compiled shell, like Elvish, leverages real-time compiler JIT (just-in-time) to provide the same REPL feel users are used to.
Bash is great, for most people. When dealing with larger pipelines, bash often runs into IO bottlenecks. Why? Well, resources. But not only that. Users can only pass text through bash pipelines, with no ability to forward complex data structures and streams. Enter shell, a retake on many modern shells, compiling your commands, running them for you, and bringing the terminal a step closer to your heart.
Installation is as simple as can be. First step is to clone the repo.
git clone https://github.com/walidabualafia/shell.gitOnce you have the repo handy, you can compile and run the C implementation.
cd shell
make
./shellIf you want to run the Go implementation, you can either compile it, or test it by running the Go interpreter:
cd shell/go
# To compile
go build
./shell
# To run
go run shell.goThe shell will also be implemented in Rust by March 1st, 2024.

-
Analyze Elvish commands and whether anything can be inherited from Elvish
-
