The ?x modifier/flag is nice, never used it before.
Makes it possible to include commentary inside complicated patterns. #perl #regex

Hey Canadian nerds! I have held the domain registration for regex.ca for a very long time. When I lived in Canada it was my primary domain, but I haven't used it for years. Does anyone on the fediverse have a good use for it?

I'm going to release it but if you've got a good pitch I'll pay for a 1 year renewal and then transfer it to your ownership.

Please boost for visibility kthx!

Lo and behold, fellow mortals of the programmer variety! I find myself embarking upon a most arduous quest.

One that shall test the mettle of my coding prowess... Yes, thee heard right.

I dare to dance with the elusive and powerful entity known as... the #regex #email #validation!

🎉 New Post Alert! 🎉

Counting words in a string is a fundamental task in data analysis.

1. Base R: Use strsplit(), a straightforward method to split strings and count words.

2. stringr: The str_split() function from the stringr package makes the code more readable.

3. stringi: For powerful and efficient string manipulation, stri_split_regex() from the stringi package is your go-to.

Happy coding! 🚀

does there yet exist any application that can take a multi-selection and spit out a #regex that will match that in any file going forward?

I’ve got an email-parsing project that will require some serious regular expressions.

It’s been a long while since I’ve written any regex. Can anybody recommend any good resources for putting off or avoiding doing it?

Any #regex wizards here?
Is there a way to match multiple linebreaks regardless of the content but only if the number of linebreaks exceeds a value like 5?

castarco, 3 months ago to til

#TIL Today I learnt that adding ? after * transforms a #regex expression from being "greedy" into "lazy" (important for performance, safe validators, and protection against DoS attacks).

I don't know how I missed this bit of knowledge for so long. :blobfoxbox:

Paczka Pythona #regex (nie mylić z wbudowanym modułem re) zbudowana jest w oparciu o szczegóły implementacji CPythona i nie obsługuje poprawnie #PyPy (i autor zapowiada, że może w końcu zablokować kompilację na PyPy). Jednakże wygląda na to, że wymagająca jej paczka #ReAssert działa bez problemów ze zwyczajnym re.

Dzisiaj #Gentoo przechodzi z łatania w sposób niedoskonały paczki regex, i ignorowania szczególnych przypadków, w których nie zadziała, na rzecz łatania re-assert. Chciałbym wysłać tę trywialną łatkę autorowi, ale — jak już wcześniej narzekałem — dostałem niegdyś bana, autor nie potrafi powiedzieć dlaczego, ale nie przeszkadza mu to uważać bana za sprawiedliwego. Może po prostu proaktywnie banuje devów dystrybucji Linuksa.

What else is as incredibly impressive, and at the same time as horrifically ugly, as #RegularExpressions?

By the way, if you need to detect #chords in a text chord chart, here is the #regex you need:

"A-G?(maj|min|m|M|+|-|dim|aug)?[0-9|11|13](sus)?[0-9|11|13](add)?[0-9|11|13]*(/A-G?)?"

edit: any #Musicians out there, can you think of any edge-case chords I should test/adjust to catch? This will be part of a Free chord chart organizer, hit me with your worst.

To my fellow #ActuallyAutistics who are also into programming. Can you handle #RegEx / #RegExp?

Up to how much complexity?

When I was younger, it was easy. Today, I have to use a test tool! ^_^;;

danrot, 4 months ago to RegEx

Generally I like #RegEx, but there are two huge problems for me with it:

1️⃣ I don't need it often enough, making it hard to remember more complex stuff.
2️⃣ As if 1. would not be bad enough, every tool and language uses a different dialect of it 😩

Remove multiple empty lines in code/text at once with Regex (www.jucktion.com)

Regex pattern to remove or replace empty lines in your code or text files to reduce the file size. Works in Sublime Text, Notepad++, VSCode…

Ich mal wieder, #IT und #RegEx
Ich will per RegEx einen String in einem Dokument finden, der immer mit ABC anfängt. Danach folgt einen unterschiedliche Menge an (unterschiedlichsten) Zeichen, und zum Schluss immer 2 Zahlen.
Ersetzen will ich danach die beiden Zahlen, ohne dass ABC oder der wilde Kram zwischen den beiden angefasst wird.

Geht sowas? Und wenn ja, wie?
(Und: Hab ich das ausreichend gut erklärt?)

(Update: Mittelteil hat unterschiedliche Zahl an Zeichen)
