JAVASCRIPT CHAT MENU SHELL - For Synchronet v3.15+ - Matt Johnson(2010)
$ID: $
*****************************************************************************
* IMPORTANT INFORMATION:
* Without customizing some binary "wallpaper" this shell is very boring
* If you wish to use this, I recommend creating a folder in your
* system.text_dir called "cshell" ("/sbbs/text/cshell/") and another within
* called "xtrn" ("/sbbs/text/cshell/xtrn/").
*
* WALLPAPER:
* file: <menu_name>.<width>x<height>.bin
* RIGHT WINDOW ICON:
* file: icon.16x10.bin
*
* NOTE: for a standard 80 x 24 terminal, menu wallpaper has a maximum
* size of 34 x 22, and the main wallpaper has a maximum size of 60 x 22,
* though these numbers largely depend on the size of the side menu and
* right window. The max width can be determined by this formula:
* WALLPAPER WIDTH =
* SCREEN COLUMNS - RIGHT WINDOW WIDTH - (SIDE MENU WIDTH + 1) - 2
*
* DEFAULT SIDE MENU WIDTH: 25
* DEFAULT RIGHT WINDOW WIDTH: 18
******************************************************************************
This shell relies on having commservice.js, commclient.js, and all other related
"/sbbs/exec/" & "/sbbs/exec/load/" files up to date. The shell will automatically
be linked to inter-BBS chat if you are running commservice.js as a node
Much of the lightbar menu code has been taken from lbshell.js, by Deuce.
