Guy comes to my desk.
Guy: Do you know Python?
Me: Yes
Guy: I want a program that reads a CSV containing IP addresses and tells which of them are valid.
Me: Sure thing. Show me the CSV file.
Guy: (Shows the file)
Me: (Writes a small function for checking whether the IP is valid)
Me: Done Here you go.
Guy: You should be using regex.
Me: Why? This is perfect. No need for regex.
Guy: My manager wants a solution using regex only.
Me: Why so?
Guy: I don't know. Can you do it using regex?
Me: Only if you say so. (Stackoverflow. Writes a humongous regex). Done!
Me: Just for curiosity, what is your application?
Guy: I will port it in Java. You see, regex is easy to debug.
Me: Ohhh Yes. I forgot that. Good luck with your regex.

Sent intern a regex pattern, mans saw it and thought I had sent him a virus.

My brain hurts just from thinking that i need to write regex

4+ years of programming.

Still have no clue how to make my own regex pattern.

Every single time I need to, I always open 4 cheat sheets and/or stackoverflow.

write regex without google

Front-end dev: email domains other than Gmail and Hotmail exist?!1! 😱 And email regex, what the hell is that? 😵

Well..

Every time I have to use RegEx...

RegEx is same magic as machine learning. You punch the keyboard untill you get desired output, just a bit less cool.

“That regex almost worked, lemme just tweak it a bit–”

API Guy.

He has a serious regex problem.
Regexes are never easy to read, but the ones he uses just take the cake. They're either blatantly wrong, or totally over-engineered garbage that somehow still lacks basic functionality. I think "garbage" here is a little too nice, since you can tell what garbage actually is/was without studying it for five minutes.

In lieu of an actual rant (mostly because I'm overworked), I'll just leave a few samples here. I recommend readying some bleach before you continue reading.

Not a valid url name regex:
VALID_URL_NAME_REGEX = /\A[\w\-]+\Z/

Semi-decent email regex: (by far the best of the four)
VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i

Over-engineered mess that only works for (most) US numbers:
VALID_PHONE_REGEX = /1?\s*\W?\s*([2-9][0-8][0-9])\s*\W?\s*([2-9][0-9]{2})\s*\W?\s*([0-9]{4})(\se?x?t?(\d*))?/

and for the grand finale:

ZIP_CODE_REGEX = /(^\d{5}(-\d{4})?$)|(^[ABCEGHJKLMNPRSTVXY]{1}\d{1}[A-Z]{1} *\d{1}[A-Z]{1}\d{1}$)|GIR[ ]?0AA|((AB|AL|B|BA|BB|BD|BH|BL|BN|BR|BS|BT|CA|CB|CF|CH|CM|CO|CR|CT|CV|CW|DA|DD|DE|DG|DH|DL|DN|DT|DY|E|EC|EH|EN|EX|FK|FY|G|GL|GY|GU|HA|HD|HG|HP|HR|HS|HU|HX|IG|IM|IP|IV|JE|KA|KT|KW|KY|L|LA|LD|LE|LL|LN|LS|LU|M|ME|MK|ML|N|NE|NG|NN|NP|NR|NW|OL|OX|PA|PE|PH|PL|PO|PR|RG|RH|RM|S|SA|SE|SG|SK|SL|SM|SN|SO|SP|SR|SS|ST|SW|SY|TA|TD|TF|TN|TQ|TR|TS|TW|UB|W|WA|WC|WD|WF|WN|WR|WS|WV|YO|ZE)(\d[\dA-Z]?[ ]?\d[ABD-HJLN-UW-Z]{2}))|BFPO[ ]?\d{1,4}/

^ which, by the way, doesn't match e.g. Australian zip codes. That cost us quite a few sales. And yes, that is 512 characters long.

When the question was "regex or regexp?"

How to regex ?

I was excited about a Hackathon... got there and the theme was REGEX! Just kill me already!

I've always had problems getting it right but it's fun when you find the correct pattern

Reading regex is way easier than understanding the mind of my non IT boss

Just saw this today, i remember how stubborn i was a year ago about learning regex.

From Reddit

Q: Is there a word that describes a fear/phobia of regular expressions?

A: Common Sense

/he/ meets "she" in a dating app.

It's a match!

Somewhere in that code there's a
"TODO learn regex"

Use regex, they said. It's better, they said.

Found this on Facebook.

Regular Expressions.

The art of combining brackets, slashes and dots until something happens.

Use regex to parse HTML.

Regex looks worse than Brainfuck

"Use a regex to parse that HTML file"

Installed my pihole a few days ago and not a very high percentage blocked.

Added google/facebook/twitter and some more to the wildcard (regex) blacklist and BAM, so many blocked queries!

Fuck Google, Facebook, twitter and other mass surveillance companies.

Today I wrote a regex expression that worked on the first try. Today I learned that the hardest code to debug is bugless code.

A small bug is found.

Chad dev:
😎 *Exists*
> Writes a simple ad hoc solution in a few lines
> Self documenting code with constant run time
> No external dependencies needed
> Fixes the bug, easy to test and does not introduce any new issues

That guy nobody likes (AKA. regex simp coder):
🤡 'This can be "simplified" into oNE LiNe'
> Writes a long regex expression that has to line wrap the editor window several times
> Writes an essay in the comments to explain it's apparent brilliance to the peasant reader
> Exponential run time (bwahahah), excessive memory requirements
> Needs to import additional frameworks, requires more testing that will delay release schedule
> Also fixes bug but the software now needs 2x ram to run and is 3x slower
> Really puts the "simp" in simplified, but not the way you would expect

"Some people, when confronted with a problem, think "I know, I'll use regular expressions." Now they have two problems." - Jamie Zawinski

The first time I learnt about regex and used it. It was magical.

We need search bars which support regex.
Everywhere.

So my teammate posted on our Slack channel:

^(?=.{1,254}$)(?=.{1,64}@)[-!#$%&‘*+\/0-9=?A-Z^_`a-z{|}~]+(\.[-!#$%&'*+\/0-9=?A-Z^_`a-z{|}~]+)*@[A-Za-z0-9]([A-Za-z0-9-]{0,61}[A-Za-z0-9])?(\.[A-Za-z0-9]([A-Za-z0-9-]{0,61}[A-Za-z0-9])?)*$

Then our manager asked him: "Are you swearing on Slack!?"

No sir, thats Regex.

If archaeologists from 1000 years in the future find a fossilized copy of your code? What would they think about it?

Regex would definitely classify as alien manufacture.

Are you a iOs developer/Android developer/graphic designer/web developer/3D artist aged 18 - 30? Are you fluent in English, both written and spoken? Well, that's nice , Good day 🤡

Computer science huh 😂

Fuck i love regex... managed to replace a series of loops and if statements with regex and cut execution time from 60ms down to 5ms

What do developers Google most?

A: Regex 😂

Last day at my current job

There ain’t no feeling like replacing 6 lines of code with 6 characters of Regex.

A few months ago my now boss, then he was my mentor and school teacher asked for my help with a feature, said he had tried for some time and couldnt get around it, I solved it with regex in less than a day, and the company is like the golden standard of my region. The issue itaelf wasnt hard but being able to help my mentor was pretty cool

Learning regex is like finding a scalpel when thus far you've been trying to dissect a frog with a chainsaw.

STAY BACK, I KNOW REGEX!!
...

Never mind, it’s been a year.. so fuck this shit..

I learned how to solve some problems using XOR.

This might be like when I learned to love regex.

*loud laugh reminiscent of Vincent Price in the Thriller music video*

What am I becoming?

Where has Sublime Text been my whole RegEx life?
Nobody burst my bubble.

I just wrote this piece of code. Without googling. Call me regex king!
But in fact regex is not that hard, you just have to learn the syntax 😄

When I was a kid I fucked with a ouija board and now trying to debug massive regex expressions I swear Satan has finally come to screw me

Just funny sorting

Oh dear, a scaling problem I solved was replacing some Regex matching with simpler string functions. While I'm a huge fan of Regex, it's unreal how much performance they can suck out of some high-n loops...
I got about 120x out of some critical code thus making a CPU upgrade unnecessary.

When your regex works but you don't know why.

Regular expressions is like a condom, it's safe, combat tested and works most of the time.
But if you use it too much it gets dirty quickly.

I guess we should call him HackerMan

import do
import re
import mi
import fa
import sol

You know which one is the real module

When developers can't use Regex:

'Your credit card number cannot contain spaces'

ಠ_ಠ

When there is no regex provided.

Atleast it works

Regex.

I HATE YOU.

There. I've said it.

I spent the better part of the last hour trying to wrangle together, not one, but TWO regexes and getting them to work with Python's "re" module.

The worst part about these little shits? It's how well they work once you figure out how to get them to work. For example, pulling a phone number out of a paragraph is difficult with string methods, but cake with regex . . . if you can figure out the pattern.

But I think I'll always have hate in my heart for Regex just for how obtuse and frustrating they can be.

F**k you regex.

When you forgot to escape characters in regex and wonder why the fuck it’s not working for 2 hours. 😖

Why regex must you be a living hell!

I've been guessing all regex's in my past projects... If I'd be in a regex written exam, I'd be a goner.
ヽ（・＿・；)ノ

Fuck regex and everyone who has ever endorsed the use of and/or is affiliated with regex.
It's unreadable, impractical, overly complex and complicated and it adds unnecessary clutter to your code, and your thought process.
It's 00:50 am and I just spent 3 hours debugging a regex only to realise forgot a single "?" in a 75+ character long string and I want to go to bed.

To all the web developers out there that use email validation, stop using a check for common domain names! If I try to sign up with my email address (something@coded-websites.be) it won't work! So stop doing that and use a RegEx please! Who has had this problem too?

New developers(5-6 years experience) these days are so pathetic. They dont have any sense of code review. All they want is to put their opinion out without giving any thought.

I had a PR for review today which contains mock specification to match a regular expression and return the corresponding response

The regular expression I put was

104000(02|06|20|48)

Now, this guy comes and puts a comment that we could "simplify" as 104000\d{2}

I replied, the ending digits are not contiguous. The specific pair of digits have to match for these mocks.

Then this guy replied, then we could simplify as 104(0{4}(2|6)l0{3}(20|48)).

I said, I cannot understand how that is simplification. Why do we need such a complex regex to match something very straight forward.

And the guy replied, we should be writing proper regexes, otherwise we could just specify everything explicitly.

I was like WTF man. You try deciphering this next week without taking at least a minute to know which values are matched.

Anyhow, another senior person approved my PR, and I merged it.

Yes you can have hyphens in email addresses, you incompetent nincompoops!!! Just use the standard regex for email validation and stop trying to make your own rules!!!!

I spent almost 10 hours coming up with this RegEx. Trial and erroring my way to hell. First I had get rid of the HTML tags (which was easy-ish) then I spent most of my time trying to figure out how to remove the god damn dash but keep hyphenated words ....... Then I found \B and look behinds...

I am making it a point to get good at this shit... Because right now I am petrified of it... Fuck you Regular expression you have taken away all my emotions...

Whomever invented regular expressions was both a genius and a madman.

Programmer 1: We have a problem
Programmer 2: Let’s use RegEx!
Programmer 1: Now we have two problems

Him: "I don't need source control, it's just another program that does unknown things on my source files. What if one day it stops working?? How do I get my files??"

Me: "you could say the same thing on 90% of the tools you use every day... Like when you restore npm packages by GUI"

him: "what are those? I don't use them"

Also him: "command line is vintage"

I found this abomination.

When a bug is what is actually keeping everything together

Yep... There's basically an app for almost everything 😂

I had a problem and I tried to solve it with regex. So now I have two problems.

I had a problem to solve. So, I used regular expressions. Now I have two problems to solve.

I feel like Stackoverflow is a fastfood for programmers mind. It gives you a solution you starve for. It may be not the best quality, but it works for now. It does not satisfy you in a long run, and may be too shallow for advancing. But it works and gives you more to think about.

I would never find a quick solution to parse a string with regex. I never thought it works this way. But hey, I'm happy.

I had to make Google forms but it got boring after sometime (with drag and drop). So, I ended up learning regex. Phew! That was little hard.

Me: yo DEV2 parse this string into a hashmap. Use regex, 2 rows of code are enough for the job
DEV2: implemented 40 rows of switch/if cases into nested for loop.

Mood of the day

That moment when you're doing regex to parse regex expression stored in a file whose name you found using a regex on input. Regex-ception

One of my classmates was working on a login form, and the fucker handtyped a 100+ character email validation regex but forgot to add a check to make sure no fields were blank.

It was funny when I was able to create an account with no username, breaking his website, and even funnier when I told him html forms have a built-in email pattern

As a community of devs I really feel our search feature should have a Regex option...

I don't see all that much point to having it but still...

After more than 24 years in dev, I still don't use RegEx and I have no idea how to write one without using an online builder.

I also refuse any Pull requests contaning regEx..

Wait for it...

Slowly getting better with RegEx problems! Warning, lots of non-computer linguistic geekiness ahead.

Been working on some functions recently to replicate the furigana (Chinese character annotation) functions available over at JP.SE in PHP for a project.

Managed to get the basic cases down fairly quick:

[Chinese character][reading] => <ruby><rb>Chinese Character</rb><rt>Reading</rt></ruby>

However I realized this evening that there are patterns where this repeats twice for one word, such as the following:

[Chinese Character][helper Japanese character(s)][Chinese Character][possibly optional word ending][reading for the whole thing]

Managed to get it working for both cases initially, but then I found out that adding a Japanese character to either of my test strings (see graphic) would cause the annotations to fall grossly out of sync. The next two hours disappeared pretty fast before discovering that the issue was that I was removing the wrong string length from the annotation string, and just happened to luck out with a test case where it worked the first time.

Probably going to do a code review of it with the intern next time he's in. One of the things I've been stressing to him lately is that however easy a task may be for a human, there are all kinds of extra things that need to be tracked in order for a computer to be able to follow your logic.

\S+?@\S+?\.\W(\.\W)?

Look at how colorful that is :D

I am in love with regex (re in py)!
It is so damn cool!
Unfortunately, Python's find is faster.
But regex is so much better when it comes to complex patterns you would not be able to find with the regular (do you see the pun here? ;)) python's string object find method.

I once reviewed some code that parsed HTML using regex (red flag #1), and it turns out that it had to be done that way because the company's HTML was so malformed that no actual parser would accept it without erroring

Ideas for a strong password:

- a regex matching my laptop's LAN IP address
- a sed command to enable X11 forwarding in sshd_config
- a shell oneliner extracting all the IP addresses from ifconfig / ip a sh
- an awk command to print processes in D state
-

Chip in!

Regex have Mind of their Own

I wonder if there is anyone who would find more clarity in the regex than the English.

I rarely use a regex from StackOverflow. Most of the time I write my own!
I'm so proud...

Came across this company when I was looking for regex for organization-ids/organization-numbers. 😂

Yesterday I learned there was a chat feature in StackOverflow. I learned this because I finally for once in my life have StackOverflow reputation.

Discussing my excitement:
“Guess what topic it was.”
“Was it regex?”
“It WAS regex!”

Fffffff uuuuu regex!!!! :@........
*then I finally get it working*
......I am king! And can now do anything!!!! :-D

That moment when you decide to look why Vim's regex rules are a bit inconsistent and find out this program has a setting called "very magic".

I used to doubt the usefulness of regex, until now.
I'm new to web dev, and downloaded a sample website to make a project with, but all the sources of images came as src="images/image.jpg", and for some reason I couldn't make it work, the only way that I found that could work to me was creating a static folder inside my app folder, declaring in the start of the document a {% load static %} and referring the image source as {% static 'images/image.jpg' %} in the html file, I kinda get what this is doing, but why it's the only way that works, it's beyond me.

Great! Now I can start the development server and see the website in its full glory!!! Then I realized: I had to edit the sources of every image and every reference to css and js in 5 html files to it work properly, and come on, do all that by hand?

Then regex came to mind, never had used it, never knew how to use it properly, after some web research I found if I did a find/replace with ([a-z]\w+\/[a-z,-]+\.[a-z]+{1,2}) and {% static '$1' %}, all the work I had to do, was resumed to a single click of replace all.

Man, I love doing what I do, and I love you guys/gals, never tough I would ever find a place in which I could share this kind of thing!

Got a ticket saying we need our website's record creation wizard to have better validation. No worries, just some regex, right?

Sure, regex for name entry (with the usual white person assumptions about names), and fixing the fact that it's in-page popup doesn't close on save. Or save draft. Or delete.

And also you need to apply the name regex for the fields on this page to all the previous names that the user lists.

And there's that one issue where the address history message always shows no matter what.

Oh and make sure that if they choose to ignore those validation issues then the validation message is in the notes for the record.

And fix the thing where it saves as draft instead of as a normal record.

And and and and and...

Can we just talk about making it 1 problem per ticket? This sort of shit makes me look bad when it takes me a week to fix 1 ticket, when I'm usually a few-a-day kinda person

When knowing regex saves the day 💪🏽

Spending 20 minutes relearning regular expressions so I can save time on a 10 min task

For some reason the backend kept throwing errors when I tried to save a long string containing markdown. Initially I assumed I must be escaping things incorrectly but that all looked fine. Asked the backend guy to take a look.

Turned out that in order to count the number of words they were using a regex, which seems fine, unless you construct the regex out of my string and run that over the word count regex... 🤔

Man, people have the weirdest fetishes for using the most unreadable acrobatic shell garbage you have ever seen.

Some StackOverflow answers are hilarious, like the question could be something like "how do I capture regex groups and put them in a variable array?".

The answer would be some multiline command using every goddamn character possible, no indentation, no spaces to make sense of the pieces.

Regex in unix is an unholy mess. You have sed (with its modes), awk, grep (and grep -P), egrep.
I'll take js regex anytime of the day.

And everytime you need to do one simple single goddamn thing, each time it's a different broken ass syntax.

The resulting command that you end up picking is something that you'll probably forget in the next hour.

I like a good challenge, but readability is important too.

Or maybe I have very rudimentary shell skills.

Regex : rocket science in programming 😹😹

I had to write a script to clean some crap from a database.
In particular it had some records containing multiple names and I had to split them.
It was really a nightmare because the separator was not always the same, e.g. "John, Mark and Bob" or "Alice+Mary".
«Ok, let's use a fucking regex: ",|(and)|\\+|/|&"»
Then, I realized there were some "Alessandro" in the database. Yeah, Aless(and)ro. Shit.
So I had eventually added more crap into the database.

Fuck regex

Yes, a plus, i.e. `+`, is a fucking valid char for an email address.

Your online service is shit, you don't know your craft, and you should feel bad about yourself!

But you thought email is fucking simple, google for email validation regex and took copy pasted the first fucking find from some random blog that validates anything but an actual fucking valid email addresses, didn't you!?

(Funfact, the plus sign allow to create email aliases in some free mailer services. GMail for instance. That's why I l like using emails like my.actual.mail+I_KNOW_WHY_YOU_ARE_SENDING_SPAM@gmail.com as my registration email. Also, brute-force that login email.)

Anyone knows why I can copy paste text with color??

If you were to write a regular expression to match phone numbers in the format of either:
(123) 456-7890 or
123-456-7890

Would you prefer a regular expression that looked like:
A) /^(?:\(\d{3}\) |\d{3}-)\d{3}-\d{4}$/g
B) ^\(\d{3}\) \d{3}-\d{4}$|^\d{3}-\d{3}-\d{4}$/g
C) Other
D) I hate regex

Reasoning? Alternative? Discuss.

Anyone else here into regex crossword? I'm quite obsessed and I'm at rank 32 now 😛

contemplating making this really simple regex stop matching dates after year 2999 just cause I think it might be funny and ruin someone's day for a few minutes long after I'm dead.

Today was not my sharpest day but managed to sit eight hours on this chair with a laptop on my arm leaning. It's very comfortable.

I made a regex interpreter. Three versions, the first one was nicely programmed and functional but found out that it was 16 times slower than the clib one (at least!). Then i found out how extremely fast the clib one was and found out that the compiling to bytecode what they do is extremely effective. So, i've wrote my one bytecode compiler that is faster than theirs. So, the second version was born. After abusing that thing to find out what kinda speeds i could get out of it, it became very unmaintainable, beyond resque. So i made third version, this one is very performant. It supports [abc]{3} (three times dupplicating group) for example. It supports 0-9 and a-z that converts to 'd' and 'a' (shorter for speed). It converts [a0-9a-z]]{3} to [lada][lada][lada]. The bytecode is not smaller many times than source, but not having to think, suits the interpreter very well. It's blazing fast.

I wish I could smth like this for a living. Develop a language for a living or socket servers. Tired of python (great language, but boring).

RegEx or RegExp?

I thought I had a great understanding of regular expressions but today I tried to use them in vim... Why the fuck they have to be so different there??

Started new course called "Introduction to natural language processing" in uni. I am super bad at doing regular expressions and don't understand anything about them.

Saw the first weeks homework. Have to do i.e. some text cleanup with regex... I was sad. But now after reading the course material and trying some of the exercises I'm super excited since I'm actually doing something "real" with it.

Do you guys just love it when teaching material is well written? I do.

Tomorrow are is my final exam in english (I'm a german).
So what did I do today?
Learning...? A bit.
RegEx...? Heck yea!

Finding out how not to do it.

An example, learning how to parse HTML, and finding a stackoverflow post with the answer "use regex" triggers tech junkies so much that they actually comment a mostly accepted way of doing something.

That great feeling you get when your teacher asks you some things about RegEx and you know fucking everything!

Regex and off by 1 capture group...

Love the UI 🔥

Is it even possible to get good enough at regular expressions where you can just write it and you don't have to search stackoverflow for one that works?

I was genuinely baffled by this until I read up more on regex flags and realised that this is the intended behaviour😂

@dfox How do you feel about an update to the profile page? I want to link to my personal website, perhaps some regex black magic to override the github link if it matches a URL?

Or just a new input?

What are you doing crashing on me Windows?

All I was doing was running a flight simulation, compiling a build, and doing a regex search over 6 directories. Try to open one little document and it all goes to hell.

Surely you can handle that Windows?

Apparently not.

Awful idea of the day - Have a programming language with no comments, but regex preprocessor macros. Use macros to define your own comment syntax and strip them before compiling.

#define /\/\/.*//

Restarting regular expression parser from scratch has been good. I am somehow both much farther to completion and farther away from completion than I was in the earlier implementation.

Further in the sense that this implementation is going to be way more flexible to changes in the language

Farther in that I haven’t even got all of the regex parts added to the first stage yet.

But I’m feeing good about it.

Even if I did refactor it so my constants are in all caps and now feel like my core is yelling at me.

Regex syntax and vocabulary when talking about it reminds me of what Scientology would look like if it had its own coding language.

two things people think they are good at, but actually have no clue about:

regex and sex

[I just needed an excuse to write a post about those two, since they sound really nice to each other :D ]

Regex is fun 😃 NOT!!! 🤯😭

Regex...

Never understood the hate for regular expressions, it's just one more useful tool in my eyes. Anyone want to weigh in?

I fucking hate css. This animation is a fucking dirty hack on top of a dirty hack on top of a selector that looks like regex that only works in chrome

Fuck me

Happy belated birthday to me

This regular expression documentation thing is coming along. Added capture groups and backreferences. Think I just need to tackle Unicode property escapes and control characters.

But now I feel like I should have implemented it differently. Like, maybe instead of “‘a’ followed by ‘b’ followed by ‘c’, I should have just done ‘abc’.

*sigh*

when you have to validate an email address to fit the requirements of some stupid mail software

(^$|^([^<>()\[\].,;:\s@!&#$%+'{}|~*="]+(\.?[^<>()\[\].,;:\s@!&#$%'{}|~*="]+)*))@((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)(\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)){3}|(([a-zA-Z\-0-9]+.)+[a-zA-Z]{2,})$)

I'm not even sorry.

Let me guess, using regexes in the mousemove event handler isn't a great idea.
How fast are simple regexes, anyway?
I have /^(\d+)(.*)$/, because I want to animate a css property that might have some unit.

bad regex/always sunny cross over

preg_match, since when you know how to regex, you feel like a God.

If plural of "index" is "indices", why is plural of "regex" not "regices"?

Quitting smoking and learning regex
