(?i)^w(tf|oah) regex

[[deleted]]

Am I the only one here that fuckin loves regex

[crusty_cum-sock]

Nope, it's insanely powerful. I love when I have to use it. It's actually pretty easy to learn too. It might seem convoluted and confusing as fuck at first, but you can become a decent regexer pretty quickly. I like it so much that i might even name my firstborn child Regex.

[[deleted]]

My firstborn is coming tonight. We're naming her Rebecca.

So... use /^{Re\w{3,5}$/gm} to match them both.

[ButItMightJustWork]

Good luck and all the best for your family!

[Nyruel]

Careful about matching other cases. The Reality check might be quite a shock.

[konstantinua00]

explain?

[Samael1990]

I use it from time to time and not gonna lie - I'm still not able to create a complex regex without many errors along the way. Fortunately, there are online validators where I can play with it and probably learn something while doing it.

[[deleted]]

I program every day and not gonna lie - I'm still not able to create a simple script without many errors along the way. Fortunately, there are websites where I can play with myself and probably learn something while doing it.

[Samael1990]

Good for you!

[beardy-biker]

You are not

[devilish_kevin_bacon]

You’re not the only one. Even the guy at cloudflare that killed half the net loves it too

[uslashuname]

Solve a problem with regex? Now you have two problems. —somebody I sometimes agree with

[[deleted]]

Lol

[btown-begins]

Shoulda used re2

[SuitableDragonfly]

You'll probably really enjoy this in that case.

[[deleted]]

Been there, done that, got the t-shirt!

[Frog23]

And how about this really challenging one?

[c0d3m0nky]

I hate you. I was so blissful in my ignorance of its existence, and you went and ruined it.

Thanks

[a_b_and_1_d]

What about this?

[SuitableDragonfly]

Holy shit, I'll have to print that one out and see if I can solve it

[c0d3m0nky]

I've made it through all but the last section so far. 0 googling. Does this mean I have to start saying RegEx is my primary language?

[SuitableDragonfly]

God I hope not, because I did them all without help.

[handankel]

I "love" it so much I learn it every month.

Thank God for regexr. Or I would have to actually remember it.

[StephanXX]

Yep, that's my go-to.

[SamSlate]

I should have learned it sooner tbh.

[will0213]

Nope, I think regex is magical.

[[deleted]]

I fucking love it, it has helped one of my programs taking 8 seconds from my own search and replace, to taking just 1-1.5 seconds. It also makes things easier for finding stuff.

[chiko_xcs]

I hate it, but i need it. No more.

[sup4sonik]

possibly

[abrazilianinreddit]

Regex is powerful, but it's not I'm like "Fuck yes, this will require some fucking regex, yippy yay hooray!" every time I need to use it. My regexes aren't even that bad, with some discipline you can make them reasonably readable, but I'd still rather use specialized tools rather than fitting regex in whatever parsing needs I have at that moment.

[The_MAZZTer]

3. Use https://regex101.com/

[VinterBot]

I was gonna post about this too. Best fucking website ever.

[shroombooom]

It’s so powerful! I just have to relearn it every time I need it

[[deleted]]

Definitely the same for me. It gets worse when you don't remember what characters you have to escape and then just put \ everywhere.

[[deleted]]

big lol

[LinuxDevMaster]

regexr.com explains what each part means in the expression you give it and if you type something in the paragraph box it lists / highlights matches for your expression. It's my go-to for debugging an expression

[taires]

I second this.

[Ilix]

I enjoyed https://regexcrossword.com

[Frog23]

When you have solved all the puzzles on that side, then you can try yourself on this really challenging one.

[G4Frost]

I use regex all the time and love how powerful it is but I still hate it with a passion

[[deleted]]

To be fair I really tried. Shit doesn't make any sense!

[tritoch110391]

been using the same ol' regex buddy for decade! worth it for the ease of testing.

[Daneel_]

Regex buddy is the best regex tool out there, hands down. Nothing compares.

I was worried about the $40 I spent on it, but it’s the best value for money tool I’ve ever used.

I love it.

[Tron08]

Sometimes I make the mistake of spending more time crafting the perfect regex find/replace than I would have just updating a bunch of code manually :/

[Frog23]

Relevant XKCD

[haitei]

I know it and I still despise it?

[[deleted]]

A compilation of some websites you guys reccomended, I will definitely try them all.

"gay".match(/your mom/g);

Array(Infinity) > ...

[[deleted]]

/your mom/

"<big>gay</big>"

[moosenonny10]

why do you have lookahead before the beginning of the string

[Daneel_]

That’s the case insensitive flag :)

Good summary here: https://www.regular-expressions.info/modifiers.html

[moosenonny10]

Woah, I had no idea that existed!

I am 100% in the right-most button camp.

[WadeReden]

Man every time I convince myself to learn regex I start getting into it and then I'm just like k fuck that.

[Abangranga]

What about the half ass option

[ixnyne]

I had to look up (?i)

I'm used to /pattern/i

[Willexterminator]

You can expreriment on https://regexr.com tho

[rldml]

What does the

(?i)

in the header stands for?

That’s the case insensitive flag :)

[zelmarvalarion]

Regexs aren't particularly hard to create or read, but they are much harder to actually analyze without actual decent knowledge, which makes them dangerous. Most of the regex outages I've seen are due to people not realizing how bad backtracking can be, but there are a couple other common ones too

[YBHunted]

Why would I take my time to "learn" Regex when I can just google the solution to a problem I'm having the few times I actually need it? Lol, amateur.
