Dear Steffan,

Thanks for that.

I come from more a Delphi (Turbo Pascal) background so please excuse
anything I say as not working from a purely C workspace.
The incorporation of a scripting language is a stroke of genius, so many
distributed editors do not do that or in Win32/64 were in the past just
plugging VBA in.


In Delphi we can extend an application's functionality using a PHP extension
which opens up all the libraries and code of PHP (
http://users.telenet.be/ws36637/php4delphi.html) this plugs into the PHP
Zend C API - you can think what I am going to ask here, can TW being a C
written application better do this as well as LUA? Or could LUA be asked to
handle this for TW - its just that there is such a wealth of string
libraries and other  platform independant libaries already available under

*Dynamic Menu / Sub-Menu Items*

I think I suggested privately to Alain (again form my Delphi background)
that the Scripts (LUA) names be utilised to show where they should go on the
Scripts menu.

I was thinking that the Scripts will be more important than many realise at
first, in that they will provide a lot of stringhandling utilities and
placement of custom tags (custom LaTeX commands), so they will probably
increase in number for many users very quickly.

This made me think from previous experiences that the Script menu would
become cumbersome and over full,  very quickly.
As (in Delphi) I am used to being able to make new sub-menus and menu items
dynamiacally at run time, I wondered whether this was possible in TW as

Thinking perhaps that the LUA script name could place it on the menu tree
and call for the making of new sub-menu(s) as needed.

I.e. lua script name:  Insert-LaTeX_Pictures_Righthand-Logos.lua

- for space
 _ for new Sub menu

Would go on Menu     Scripts/Insert LateX/Pictures/Righthand Logos

Or perhaps it could be a property of the script  in the Script Management
tool, plcaement on which (sub)(sub)Menu?

It would be a great help to us users!
