Luaetta

Luaetta is a suite which consists of an unique Lua application for the web and a Lua library which eases developing of web applications in Lua. Written in C++, this is similar to PHP but more secure, faster and a lot more flexible.

Project Start: August 2007
Project Status: in development

Currently there are two source bases, neither officially released but some people have it.

Luaetta
Luaetta-ng

Current lack of a lot that would one call web framework, just some URL handling. Stuff like theming, database access and a lot stuff is still evaluated.

Ideas

Luaetta is split up in two parts. The Luaetta executable which is the FastCGI component and Luaetta Lua library.

Requirements for a templating system

  • Should seperate presentation and logic as much as possible
  • Seperate the role of the designer and the developer
  • Template creation should be as simple as possible, and not too far from creating a normal (X)(HT)ML page
  • Exposing information to the template from the code should be easy

Requirements:

  • handling forms and binary data, even mixed
  • don't overload the lua stack with large binary blobs
  • easy handling of long upload processes

All solutions refer to this example: 
  1. Content-Type: multipart/related; boundary=f93dcbA3; type=application/xml; start="<980119.X53GGT@example.com>"
  2. Content-Length: xxx
  3.  
  4. --f93dcbA3
  5. Content-Type: application/xml; charset=UTF-8
  6. Content-ID: <980119.X53GGT@example.com>
  7.  
  8. <?xml version="1.0"?>
  9. <uploadDocument>
  10.   <title>My Proposal</title>
  11.   <author>E. X. Ample</author>
  12.   <summary>A proposal for a new project.</summary>
