010101 what's your error?
Hashtag
Justoverclock Same as before. Invalid regular expression. Safari/iOS doesnāt like it. Thereās a lot of posts online about it.
Justoverclock This simulates look behind. So it could fix it.
interesting, do u know how it works?
Justoverclock Never mind on the above. I may have found a solution... Pull request submitted. Test it out.

010101 this will parse even https://docs.flarum.org/#about-flarum anchor tag...so i think is not good

Justoverclock Oops, ok, try new pull request...

Just some slight differences which Safari is OK with. And should work with all languages.
Oh shoot. It's SO close... I just realized the latest one is ignoring anchor tags and other characters but it's including the preceding space...
010101 yes i was about to write this to u....we are close btw 
Justoverclock I'm not sure why but simply adding a space on line 15 where the hyperlink is created makes it work...
010101 with your last regexp? can u provide the string so i can make some test?
Justoverclock You won't be able to just test it with the regex online tool. There's something about adding a space before the anchor on line 15 that makes it fully work.
010101 yeah i will test on a local flarum
@010101 unfortunately even this one can't work, because if u add 2 hashtag in the same post, the second return with "#" in the generated link

Justoverclock Wow. Well, one of these times I'll get it. Another pull request is coming your way. This could be the winner. This solution adds in a couple extra .replace() and .trim() methods.
Justoverclock Fingers crossed!!
