The Perverse Beauty of Regex: A Love Letter to the World’s Most Efficient Torture Device
It starts innocently. You just want to search for something. A word, a phone number, perhaps the occasional email address belonging to your former classmate who still owes you £60 for books. You could do this the normal way, with a search box like a civilised human, or you could

Like global search and replace but don’t like surprises?
Check out serpl – a handy little command-line app that gives you a visual preview of the changes you are about to make. You can even go in and remove the replacements you don’t want from the source previews. The regex support appears to be basic, however (I couldn’t get a negative lookbehind to work).

KI generierter Code macht ja den Menschen nicht nur dümmer. Ich brauchte heute ein Tool um aus Config-Dateien sensible Informationen zu maskieren. U.a. auch Domains. Hatte erwartet, dass da ein paar RegEx's eingebaut werden. Stattdessen kam Codex mit https://publicsuffix.org/ um die Ecke. Kannte ich nicht. War d…

Do you use LLMs to generate regular expressions? We do, too! Do you *review* your regexes? Is that frustrating? How can we put humans in the loop better, doing relatively few, meaningful tasks? Please try out our new tool PICK:regex, available for VSCode!

Has anybody reading this worked on Google’s RE2 C regex library? I have an amusement for you if so.

For Day 2 of #AdventOfCode I did a stupid and slow solution for part 1 and an even slower and extremly stupid solution for part 2 (using autogenerated and some handcrafted(!) regex).

Regex is kind of a nightmare, but it's so satisfying when it finally works.

you can bring down 20% of the internet with a single-character typo in a regex, but you can also destroy a nearly 50 year old bridge with a single incorrectly placed piece of heatshrink

@… #AskFedi I need a regex (for Discord’s AutoMod) that prevents any text in all Unicode “fonts” from being sent. By “Unicode fonts” I mean things like these:

Unicode Font Style Converter - TextEditor
Enter your text in the input field above or click the random text button and see your phrase converted instantly to more than 60 unicode font styles

Oh, how glad I am that I told Claude (command-line version) about `rename -n`. Seeing it iterate over half a dozen different regex patterns that might do what I wanted it to do, but were not quite right … lucky it could spot its errors before running the real thing.

OH on slack: sometimes you think, "Oh, a regex could solve this." Now you have two ~problems~ administrators on your github repos

I wish they'd either make Mastodon filters case-sensitive or allow regex

100k most used passwords
These are the latest 100k most insecure used (hacked?) passwords. I wonder why at least a minimal regex the first hurdle can stand in the way of the attackers, i.e. apparently has not yet been widely implemented? Am I wrong, or are there reliable sources?
