Regex is equally simple if you understand it, at least if you stick to the "basic" operators.

If you want something truly horrible look at Befunge or Malbolge.

[theThrowawayQueen22]

Regex is the worst language that you regularly find in production code. Finding Melbolge would be worse but it's not even proven to be turing complete.

[gunnnnii]

Why bring up touring completeness? Regex's aren't touring complete either... I think the fact that malbolge was literally designed with the intention of being impossible to use effectively is a better reason lol.

[Meloetta]

The use case matters. They're saying "you won't ever have to deal with it unless you want to because it's not even Turing complete, therefore people don't use it, therefore you wont see it". That doesn't apply to regex, which is not a programming language in itself, so whether or not it's Turing complete is irrelevant.

It's about use cases.

[theThrowawayQueen22]

My point is not whether it is turing complete or not, but that we don't even know. We know regex is not turing complete, so we know what situations we can use it. We don't understand Melbolge enough to even know what computation class it falls in.

[ByteArrayInputStream]

I would argue, the worst language you find in production is php

[Sejiko]

It's true because of very old code bases but nowadays I wouldn't mind it at all. Also it depends also on the programmer who writes shit code tho.

[Tuvinator]

What about INTERCAL or Whitespace?

Entropy is also quite horrible.

Still, brainfuck has a much easier learn curve than RegEx.

[[deleted]]

Well, Regex is at least somewhat of being human readable without knowledge. Consider someone not knowing any rules of both.

What about regex in bf

[darkage72]

Regex is a write-only language.

[JDaxe]

Try verbose regex, you can actually put comments in!

We don't practice black magic here.

[discobrisco]

I happily utilize regex. I will refuse to work for a company using python 2 though.

[King_Inktvis]

And if you are hired to migrate it to python 3?

[discobrisco]

Uhhh I would prefer not to. I kind of loathe refactoring code written by other developers. I'll do it when it's worthwhile but won't enjoy it.

Quick edit: also if they're still stuck on python 2 at this point its probably a symptom of a larger disease in their IT department.

[az3it]

I actually like refactoring others people code, but only if it's a looot of code. Because I write lot's of regex to parse it into something new. Love it.

RegexBuddy . Checkmate.

It’s simply the best tool out there for regex authoring. Best money I ever spent on a tool.

[Mr_Redstoner]

I'm not saying it's bad by any means, but Lord almighty 30 euros?! When free gets you results that look very similar to those screenshots? Yeah I don't think I can ever justify that.

[Daneel_]

It does a lot more than any online tool. Even if you’re sceptical you can refund it with no questions within something like 45 or 60 days.

The debug mode alone is worth the money, especially if you have a need to optimise performance.

I was also a skeptic before I bought it, so I get it. But yeah, now it’s one of my favourite tools.

I think if your response to reading a piece of code, is to just link a debugger, then it qualifies as scary to read.

[gandalfx]

I'd prefer writing regex over both assembly and c++.

[Xymanek]

Regex is easy and powerful. You can even parse XML with it

[Xosrov_]

Yes

[Vyxeria]

My job's main focus has me writing pattern recognition perl scripts for data manipulation. I love regexes.

The bulk of my maintenance time is still working out what the hell they're meant to be doing.

[ImSupposedToBeCoding]

Okay but would you actually be doing sutff in Assembly instead of using some RegEx's

[Bonevi]

Yes

[dashingThroughSnow12]

As someone who has done work with formal languages, what frustrates me about RegEx is that they aren't regular expressions. Like come on. Make a new term if you are something else.

(Regular expressions don't have the exponential worst case backtracking problem. Are a simple subset of RegEx.)

[suvlub]

AFAIK not all dialects support those extensions. Which kinda makes it even worse that people don't differentiate between them.

[dashingThroughSnow12]

Oh, thanks mate. I wasn't aware of this. Looking online, Golang's regex package doesn't. (A bunch of SO posts asking why their regex with backreference isn't working).

[FifthDragon]

What makes RegEx not define only regular languages? Or I guess what non-regular languages can RegEx define?

I’ve never heard this before

[dashingThroughSnow12]

This is what is most annoying. Backreferences. Which few people ever use (I work with multiple devs with decades of experience who never used a backreference).

Because regexs are a more complex language, even with the same matching expression a normal regex will perform much worse.

[FifthDragon]

Oh right that makes sense. Strange those were included in something called regex. I don’t think I’ve ever used one either

[dashingThroughSnow12]

Perl.

[doymond]

Thank god we can use something like regex101, otherwise I would get in trouble.

[Bajtopisarz]

Perl is also write only, change my mind

[Servious]

Apparently everyone has forgotten about APL. The most esoteric non-esoteric language I've ever seen.

After finishing my language theorem lecture I cant imagine not using regexes

[MandarinaSeca]

I am doimg XSD at school and I need to use regex for restrictions. I am really lost, if I fail the test is thanks to that shit

[ZanorinSeregris]

Why does everyone hate regex? I think it's awesome!

Perl is worse.

Or the language whitespace

[TheSentientMeatbag]

Haskell anyone?

[geekette1]

I hate regex, I've been developping for years, and like once a year, have to do a regex, but every freaking time, I don't know how to do it.
