Source-mapped stack traces in Tail Workers require unhandled exceptions

Summary

We're building error monitoring with a Tail Worker and want source-mapped stack traces. We found that only unhandled exceptions populate the exceptions array with source-mapped stacks - meaning you can't have both a custom error response AND source-mapped stacks in the Tail Worker.

What we want

Custom error responses to clients (not Cloudflare's generic error page)
Source-mapped stack traces in our Tail Worker for alerting

I've been moving my blog to Astro and needed to add a slug property to each file. My files had a permalink that included the slug but I needed just the slug as a standalone property.

✅ Script did exactly what I needed ✨

The prompt

(With my babashka scripting context window attached)

A small babashka script to convert HTML from stdin to hiccup and pretty print it.

I use this inside NeoVim with this config line

command PasteAsHiccup r !pbpaste | html2hiccup

And then whenever I want to paste some HTML as Hiccup I'll do :PasteAsHiccup.

deps.lua is an all-in-one script containing your declarative list of dependencies and installing any missing ones.

Kind of like Clojure's deps.edn except that the dependencies and code to download them are bundled in one package.

add link from file to gist so people can find back to here
add entries to .gitignore if available
? if file ends in .fnl, download fennel.lua and compile to respective .lua file location

Usage in a `fennel` script
