Pavel Sapehin<p>Good luck to me finding a regex that worked among those that didn't in the search history <a href="https://mastodon.social/tags/regex" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>regex</span></a></p>
Schenkl<p>Mal eine Frage zu <a href="https://chaos.social/tags/Regex" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Regex</span></a>.</p><p>Eins hat ja immer mehrere Optionen, wie Regexen geschrieben werden können.</p><p>Wenn ich jetzt bspw. folgendes matchen will:</p><p>2025-04-03 09:45:52,731 INFO</p><p>Mach ich dann eher A oder B?</p><p>A: ^[0-9]{4}-[0-9]{2}-[0-9]{2}\s+[0-9]{2}:[0-9]{2}:[0-9]{2},[0-9]{3}\s{1}(?P&lt;level&gt;[A-Z]*)</p><p>B: [0-9-:,\s]*(?P&lt;level&gt;[A-Z]*)</p><p>Welche Variante ist denn schneller?<br>Was ist hier besser?</p><p>:BoostOK: :ReplyOK:</p>
Andrew Tropin<p>I'm really puzzled by notmuch's regexs. How the hell more inclusive search terms giving less matches?

Skalad<p><a href="https://mastodon.social/tags/PokemonGO" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PokemonGO</span></a> does not have a good way to monitor friends' inactivity. Given that I keep hitting the friend limit I am trying to figure out a way to document. Try number current, I have a <a href="https://mastodon.social/tags/python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>python</span></a> script running that reads a screen recording of scrolling through my friend list and runs ocr and <a href="https://mastodon.social/tags/regEx" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>regEx</span></a> to give me a snapshot of some stats. If I do this again in a week or three, anyone who hasn't changed has been identified as inactive. [This would be a better blog post than micro-blogging thread]</p>

Dan Neuman 🇨🇦<p>Hey, does anyone have recent experience with trying to get an LLM to make regexes for you? Does it work?
