Lua Lua, Everywhere!

Lua is now embedded in AOS, it was a lot easier than I thought. The code is ANSI C so I embedded it into a DLL with ability to dynamically load Lua libraries. I added it to the templates which now behave similar to JSP pages with Java embedded in them. For example:

header.html

<>Page for %[LUA]{{{
print(
aos.emit("/root/REQUEST_HEADER/ACookies/username")
);
}}}[LUA]%< /sometag >

Since you can combine a set of templates to make a full page, you can have a common header/footer/etc pages that are shared by many other pages. And here aos.emit() extracts from the XML model the cookie named username and
using alibrary.print() function writes it to the output stream.


It's very easy once you get used to Lua (and in spirit of C almost everything is defined via libraries); so getting used to it is actually very easy. Try it out: http://www.lua.org/ and if you are not completely satisfied, I'll refund your ... umm... it's free!
