Zrc, I tried making a Unix shell scripting language with Tcl syntax

What it does

The Zrc UNIX shell and scripting language. Contribute to Edd12321/zrc development by creating an account on GitHub.

This is the new, better and REWRITTEN version of Zrc (master branch)! It has way less bugs, a better codebase, nicer syntax, etc. Zrc is a small scripting language for Linux, BSD, etc. written in C++ (interpreter + builtins in a very small ~4000SLOC). It is a shell with syntax similar to Tcl/TK ( EIAS ). The code is quite small, but minimalism is not the main focus of Zrc (which is why it has way more "luxury features" compared to usual shells). Instead, the idea is to be a better alternative to tclsh that extends its syntax and adds features like job control, a custom line editor and more, while still almost keeping Tcl's "pure syntax". Note : The shell is experimental and behaviour may…from github.com

In the maker’s words, at launch

Welp, second time posting this project! Bourne shell's ALGOL-inspired syntax seems a bit verbose, and while `rc` is quite nice, it lacks some features I'd prefer in a shell (this is probably by design). Though don't let the name I chose fool you, this shell is probably more related to `tcl` or `csh` than `rc`, except…

  Warp, a Rust-based terminal2022 · warp.dev · ▲946

  Hi HN community, I’m Zach, founder and CEO of Warp, and am excited to show you Warp, a fast Rust-based terminal that’s easy to use and built for teams. As of today, Warp is in public beta and any Mac user can download it. It works with bash, zsh, and fish. The terminal’s teletype-like interface has made it hard for the CLI to thrive. After 20 years of programming, I still find it hard to copy a command’s output; I always forget how to use `tar`; and I always have to relearn how to move my cursor. To fix fundamental accessibility issues, I believe we need to start innovating on the terminal,…

  Going into freshman year, figured I should build an interpreter2023 · ▲138

  Hi all! I'm going into my freshman year, and figured that the best way to prepare for the intro to programming Racket course would be to implement my own garbage-collected, dynamically typed, functional programming language in C ;) Anyways... here's the repo: https://github.com/liam-ilan/crumb I started learning C over the summer, so I still have a whole lot to learn... Any feedback would be greatly appreciated! :D

  Interactive Common Lisp: An Enhanced REPLDec 2025 · github.com · ▲101

  I created this because sometimes I want more than rlwrap but less than emacs. icl aims to hit that middle sweet spot. It's a terminal application with context-aware auto-complete, an interactive object inspector, auto-indentation, syntax colouring, persistent history, and much more. It uses sly to communicate with the child lisp process and aims to be compatible with any sly-supporting implementation. I hope others find it useful!

  Ced – C REPL in 50 lines of POSIX shellMay 2026 · codeberg.org · ▲5

  Yesterday, I found myself writing a little C throwaway script to test something out. That happens often enough to clutter my HOME and some other directories with these useless text files and binaries. So I thought that I can use a repl instead. Quick google search didn't find any good and tested solutions. So I wrote my own with help of a tcc compiler. Why POSIX Shell? Because it would be far too easy in a normal language (it'd probably take me ~10 minutes to rewrite this in Nim) and where is fun in that?

  A Lisp Interpreter for Shell Scripting2025 · github.com · ▲114

  Redstart is a lightweight Lisp interpreter written in C++ with a focus on shell scripting. It lets you combine the expressive power of Lisp with the practicality of the Unix shell: you can run commands, capture output, pipe between processes, and still use Lisp syntax for logic and structure. Think of it as writing your shell scripts in Lisp instead of Bash.

  Term.everything – Run any GUI app in the terminal▲1,094

  I made a built-from scratch Wayland Compositor to display any GUI app* in the terminal! I think there is a lot of unexplored potential in custom Wayland compositors, a lot of really cool things you can embed existing applications into! So, I started with embedding apps into the terminal because that is the easiest input/output (output is just utf-8 and I use the great `chafa` library for that, and I just read from stdin for the input). If you have any other ideas for cool Wayland compositors, let me know. I purposedly wrote 80% the app in Typescript to appeal to the most developers and…

  I recreated Windows XP as my portfolio▲1,032

  Years ago I stumbled across a basic version of this concept and it stuck with me. I knew if I was ever going to take on such a project, it would need to be flawless, but without coding experience it was just another idea that would never happen. By the end of 2024, as AI coding tools exploded everywhere, I finally had a way to make it real. I started from zero knowledge and spent months collaborating with AI agents as a learning experience. Every pixel and every function went through me. The AI translated what I asked for into code, but every decision was human. I didn't use existing OS…
