AI Rules

Guys it's 2026, if you're not using AI at this point you're falling behind. That being said this community is not for showing off AI prompts that you put into gh Copilot or Claude or whatever, all that's showing the world is "hey I know how to make something up and explain it in 20 words while having the expectations of a team who gives a shit! Woow look at me!!".

So do your best to disclose where/how/why you used AI in your code, and if you suspect a project is entirely AI generated slop,, don't engage, don't bully, just let them eat their foot ¯\_(ツ)_/¯.

I cannot ever be sure about this but this might have come to me in a dream. I just thought about why it's so hard to implement a web-server in bash, basically all the functionality of the webserver must be implemented in bash but the http handling can be compiled.

This program lets you declare endpoints and map them to shell commands, query args get passed as ENV vars, methods are enforced, body is passed in stdin and the response is the stdout.

I also learned I really like declaring flake.nix files for all my personal projects, I hope it helps you install what I create!

for the common use cases, I imagine you're better off using https://github.com/adnanh/webhook instead. handles security etc. don't think it lets you return responses but at that point you probably want a proper server framework
