[ACCEPTED]-regex to find url in a text-regex

I looked into this issue last year and developed 12 a solution that you may want to look at 11 - See: URL Linkification (HTTP/FTP) This link is a test page for the 10 Javascript solution with many examples of 9 difficult-to-linkify URLs.

My regex solution, written 8 for both PHP and Javascript - is not simple 7 (but neither is the problem as it turns 6 out.) For more information I would recommend 5 also reading:

The Problem With URLs by Jeff Atwood, and
An Improved Liberal, Accurate Regex Pattern for Matching URLs by John 4 Gruber

The comments following Jeff's blog 3 post are a must read if you want to do this 2 right...

Note that this question gets asked 1 a lot. Maybe do a search next time :)

You can't do this perfectly with a regular 5 expression. You may be interested in this blog post. There 4 is a bit more information on Regex Guru, but even 3 those look very fragile. You will need 2 to have additional checks outside of your 1 regular expression to catch the edge cases.

Identifying URLs is tricky because they 15 are often surrounded by punctuation marks 14 and because users frequently do not use 13 the full form of the URL. Many JavaScript 12 functions exist for replacing URLs with 11 hyperlinks, but I was unable to find one 10 that works as well as the urlize filter in the 9 Python-based web framework Django. I therefore 8 ported Django's urlize function to JavaScript: https://github.com/ljosa/urlize.js

It 7 actually would not pick up the URL in your 6 example because there is a colon right before 5 the URL. But if we modify the example a 4 little:

urlize("I love this website: http://www.youtube.com/music it's fantastic", true, true)
=> 'I love this website: <a href="http://www.youtube.com/music" rel="nofollow">http://www.youtube.com/music</a> it&#39;s fantastic"'

Note the second argument which, if 3 true, inserts rel="nofollow" and the third argument which, if 2 true, quotes characters that have special 1 meaning in HTML.

This might work->

\b(([\w-]+://?|www[.])[^\s()<>]+(?:\([\w\d]+\)|([^[:punct:]\s]|/)))

Found it somewhere

Will 2 find links ->

http://foo.com/blah_blah/

(Something like http://foo.com/blah_blah)

http://foo.com/blah_blah_(wikipedia)

Hope this 1 works....

i am using this regex : :) ( its translated 1 ABNF )

You can use the following regex expression 2 for extracting any type of url coming in 1 message.

String regex = "(http(s)?:\/\/.)?(www\.)?[-a-zA-Z0-9@:%._\+~#=]{2,256}\.[a-z]{2,6}\b([-a-zA-Z0-9@:%_\+.~#?&/=]*)";

Typescript/Angular

This works for me:

const regExpressionUrl = new RegExp(/(https?:\/\/[^\s]+)/g); //detect URL
