ChatLite extension for PunBB 1.3
This extension adds an ajax based chat to your forum index. Only registered members can post messages on it.

ChatLite 0.5.1

Installation:
Download the zip and extract it in your PunBB's extensions folder, then access administration and launch install.

Upgrade:
Replace content of ek_chatlite folder (in extensions) with the one of the last version's zip, then launch upgrade in administration.
/!\ do not replace ek_chatlite/data/chat.dat if you want to keep chat's messages.
/!\ when updating from 0.3.3 or lower version you MUST replace ek_chatlite/data/chat.dat, all chat messages will be lost.

Features:

• Purely javascript based, will not work at all without it activated (but no dirty html parts will be shown in this case).

• CSS style that will fit default theme (see HowTo below to make your own)

• Languages support (see HowTo below).

• Timestamps in front of messages, with date if not posted the same day.

• Logs a maximum of 50 messages.

• Decent server load, doesn't start entire forum script to refresh chat content, only to write a new message.

• Refresh occurs every 2.5s and will slow down if no new messages are received until intervals reach 60s. Resets when a message is received.

Requirements:

• PHP 5.2.1 (or greater)

• PunBB 1.3 (or greater)

• Prototype 1.6.0.3 (included)

• Apache server (recommended)

Notes:
I'm not open to any feature suggestion at the moment (no time) but I welcome any code improvement.
Will correct bug or security flaw.

HowTo...
...translate
Copy ek_chatlite/media/js/lang/English.js and name it according to the language you want. Then open it in a text editor and replace the sentences on right by the translated ones.
If your text contains single quotes ( ' ) or backslashes ( \ ) you must add an additional backslash before ( \' or \\ ).
Feel free to send me your work at nk.punbb at eikylon.net (include your name and website/email for credits).

...make your own css style:
Just place a file in ek_chatlite/media/css with the same name as your forum's theme (i.e. theme.css).

...tweak message display:
open ek_chatlite/media/js/chat.js and look for:
'#{a}[#{d}#{h}:#{m}] <strong>&lt;#{name}&gt;</strong> #{msg}<br />'
This is the message template, #{xyz} values are filled when reading messages, you can modify it as you want.
#{a} is the deletion button, #{d} is the day, rest is self explanatory.

Additionally you can change day display in lang file. Using "date" as value will display the date (i.e. 11/12) anything else will be used as string (i.e. today).
