This should be easy, but I'm not sure how to best go about it. I have a WinForms app that lets the user type in long descriptions. Occaisionally, they would type in URLs, and the RichTextBox would recognize them and make them clickable when displayed.
I'm moving the app to the web, and I'm not sure how to make those same URLs clickable. Is there some semi-automatic way to convert "http://www.google.com" or "www.google.com" to clickable links? Do I have to resort to RegEx matching?

Under Settings, select Share, Copy & Paste. Under Share, Copy & Paste, select the default option you want: Link, to paste the URL as a hyperlinked title, or Plain text, to paste the URL as a web address.
Here's a few things you should know about plain text emails: You can't control text size to make headings stand out, or emphasize words with bold, italic or colored fonts. It's not possible to include images or use hyperlinks in plain text emails. Only basic reporting is available.
The website's URL is in the address bar, which is usually at the top of your web browser window. This bar may be at the bottom of the window in Chrome on some Androids. Copy the URL. If you want to paste the URL into a message, post, or another app, you can copy and paste it from the address bar.
php use VStelmakh\UrlHighlight\UrlHighlight; $urlHighlight = new UrlHighlight(); // Extract urls $urlHighlight->getUrls("This is example http://example.com."); // return: ['http://example.com'] // Make urls as hyperlinks $urlHighlight->highlightUrls('Hello, http://example.com.
It's actually a very difficult problem. You can get close, but not perfect, with regular expressions. There's a very nice breakdown of potential regex patterns to consider here: http://www.regexguru.com/2008/11/detecting-urls-in-a-block-of-text/
The last one he lists seems like it's probably good enough for most purposes:
\b(?:(?:https?|ftp|file)://|www\.|ftp\.)
(?:\([-A-Z0-9+&@#/%=~_|$?!:,.]*\)|[-A-Z0-9+&@#/%=~_|$?!:,.])*
(?:\([-A-Z0-9+&@#/%=~_|$?!:,.]*\)|[A-Z0-9+&@#/%=~_|$])
