Forums Scripts & Popups Spaces and $+ ?

I'm wondering how you add a space (" ") to a variable or between variables when using the $+ identifier.

For example, say I have two variables

%one = One
%two = Two

Let's say I need it returned like "One Two". However, if I do this:

echo %one $+ %two

It returns "OneTwo" without the space between them. How do I add a space between the two variables?

Help is much appreciated

echo %one %two

?

Thanks! That worked.

Or: echo $+(%one,$chr(32),%two)

OK< another question... I'm trying to write a script to intercept URLs in text and do some stuff with the URL, eventually adding some text after the URL. For example..


<Tony311> this is a url: http://google.com Now go visit it

should end up being

<Tony311> this is a url: http://google.com [text] Now go visit it

Is there any way to get the string that matched $regex? Like, "some stuff here", where the regex string is stuff.* would return "stuff here". But I can't find any way to get the matched string. Currently I'm trying to use $left and $right, but it's getting complicated.

You can use back references. Basic example:

If you give a concrete example, this could be improved

Okay, I can do that. I'm writing a script that intercepts URLs in channel text, opens a socket to the URL, and adds the title of the page after the URL, so you'd end up with something like

<Tony311> go to http://mirc.com [mIRC: Internet Relay Chat client] to get mirc

I already have all of the socket stuff done, I'm just working on intercepting URLs now. Each time someone says something, the script will use regex to find any URLs, then (this is what I need the matched text for) it will take the matched URL, return the title, and echo the timestamp, username, message, the url, and the title in place of the original message.

This is the regex i've been looking at (found it on some site):

https?://([-\w\.]+)+(:\d+)?(/([\w/_\.]*(\?\S+)?)?)?

The problem is, if I use $regml, it only returns the domain name, not the request string (/whatever/whatever.something.php) or the prefix (http://).

Hum, I roughly modified this regex to capture the whole url with prefix:
- adding a capturing set ot round brackets at the start and at the end
- making the sub-sets of round brackets non-capturing by adding "?:" at their start
- escaping the /-slashes as they would be interpreted as a metachar, so you can use the g parameter to capture multiple urls on one line

To: /(https?:\/\/(?:[-\w\.]+)+(?::\d+)?(?:\/(?:[\w/_\.]*(?:\?\S+)?)?)?)/g

captured urls: 2
1 : http://www.mirc.com/mirc.html
2 : https://forums.mirc.com/ubbthreads.php

It won't capture the last url, as this one doesn't include a http(s) prefix - don't know what exactly you'd like to match.
Furthermore, I'm no regex pro. And this one really doesn't look neat. For sure someone else will be able to improve it a lot

Thanks a lot! I'll get to work right away.

This regex will echo the whole set of an url link said in a channel. I'm unclear as to what you're wanting to get though.

Ok I'm using Horstl's code, it works pretty fine except for two things:

1. If the URL points to a redirected page, the socket doesn't follow the redirect and instead returns a 301 or 302 response.

2. The regex string isn't recognizing domains such as co.uk
EDIT: Turns out it's linefeeds causing this problem, the co.uk part is probably fine. So if a page looks like:

<title>
Page Title
</title>

It's not recognizing it. Anyone know a workaround?

I've tried replacing linefeeds with whitespace in the returned text but apparently, the response event runs once for every line of HTML returned - so if the titlew tags are on separate lines, there's no way to compare them and get the center, unless a much more complicated setup is used to watch if there's a title on one line, and save each line, and if it finds a </title>, return the last line, etc. etc. etc. I'm hoping there's an easier way around this.

I'm considering setting up another regex and if it finds a redirect, it returns the link and opens a new socket to the new, redirected URL.
