Parinfer is a tool designed to simplify writing Lisp code by automatically managing parentheses. It infers bracket placement based on indentation, reducing the manual syntax burden that typically makes Lisp challenging… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Parinfer – a simpler way to write Lisp launched in 2015; newer entries below may have overtaken it.

    Interactive Common Lisp: An Enhanced REPL▲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!

    Sol – A de-minifier for shell programs▲147

    I've built a tool called sol (like "soul") that helps you inspect and format complex shell one-liners. Features: - Choose which transformations you want (break on pipe, args, redirect, whatever) - "Peeks" into stringified commands (think xargs, parallel) and formats those, too - Auto-breaks at a given width (e.g., 80 characters) - Shows you non-standard aliases, functions, files, etc. that you might not have in your shell environment - Breaks up long jq lines with jqfmt because—let's be honest—they're getting out of hand As a security researcher and tool developer, I often encounter (or…

    A Lisp Interpreter for Shell Scripting▲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.

If someone sent me a Parquet file, I used to open DuckDB or Polars just to see what was inside. Now I can do it with one command. Repo: https://github.com/kaushiksrini/parqeye
