The original perl LE CHAT script by Lucky Eddie can be downloaded at http://4fvfamdpoulu2nms.onion/lechat/ or via a tor2web proxy like https://4fvfamdpoulu2nms.tor2web.blutmagie.de/lechat/ if you don't have TOR installed.
If you add your own cool features or have a feature request, please tell me and I will add them, if I like them.
Please also let me know about any bugs you find in the code, so I can fix them.
@ -71,6 +71,19 @@ When you are done, you have to edit the chat script, to include your translation
to the $L array in the load_lang() function at the bottom, similar to what I did for the German translation.
Please share your translation with me, so I can add it to the official version.
REGEX:
Yes, the chat supports regular expression filtering of messages. As regex tends to be difficult for most people, I decided to give it an extra section here.
Regex is very powerfull and can be used to filter messages that contain certain expressions and replace them with something else.
It can be used e.g. to turn BB Code into html, so it is possible to use BB Code in the chat to format messages.
To do this, use this Regex-Match '\[(u|b)\](.*?)\[\/\1\]' and this Regex-Replace '<$1>$2</$1>' and your text will be '[b]bold[/b]' or '[u]underlined[/u]'.
You can also use smileys by using this Regex-Match '(?-i::(cry|eek|lol|sad|smile|surprised|wink):)' and this Regex-Replace '<img src="/pictures/$1.gif" alt=":$1:">'
And now if you enter ':smile:' an image with the smiley will be loaded from your server at '/pictures/smile.gif'.
The following should be escaped by putting '\' in front of it, if you are trying to match one of these characters '/ \ ^ . $ | ( ) [ ] * + ? { } ,'.
I used '/' as delimiter, so you will have to escape that, too. The only options I used is 'i' to make the regex case insensitive.
If you want to test your regex, before applying you can use this site and enter your Regex and Replacement there and click on preg_replace: http://www.phpliveregex.com/
If you never used regex before, check out this starting guide to begin with regular expressions: http://docs.activestate.com/komodo/4.4/regex-intro.html
LIVE DEMO:
