LuxModule: lux_ext

The LuaExt module contains lua code and descriptions that are from mainly from other lua projects. We always refer to the original sources and we want to point out here that most stuff in this module ist not written by us.

We include this here for completeness of the documentation inside Lua.

We only list here software and documentations from projects that are published as GPL or MIT license. In case that you disagree with this, please tell us.

Lua (from http://www.lua.org):

The standard Lua libraries provide useful functions that are implemented directly through the C API. Some of these functions provide essential services to the language (e.g., type and getmetatable); others provide access to "outside" services (e.g., I/O); and others could be implemented in Lua itself, but are quite useful or have critical performance requirements that deserve an implementation in C (e.g., sort).

All libraries are implemented through the official C API and are provided as separate C modules. Currently, Lua has the following standard libraries:

  1. basic library;
  2. package library;
  3. string manipulation;
  4. table manipulation;
  5. mathematical functions (sin, log, etc.);
  6. input and output;
  7. operating system facilities;
  8. debug facilities.

Except for the basic and package libraries, each library provides all its functions as fields of a global table or as methods of its objects.

Sockets (from http://www.cs.princeton.edu/~diego/professional/luasocket/)

LuaSocket is a Lua extension library that is composed by two parts: a C core that provides support for the TCP and UDP transport layers, and a set of Lua modules that add support for functionality commonly needed by applications that deal with the Internet.

The core support has been implemented so that it is both efficient and simple to use. It is available to any Lua application once it has been properly initialized by the interpreter in use. The code has been tested and runs well on several Windows and Unix platforms.

Among the support modules, the most commonly used implement the SMTP (sending e-mails), HTTP (WWW access) and FTP (uploading and downloading files) client protocols. These provide a very natural and generic interface to the functionality defined by each protocol. In addition, you will find that the MIME (common encodings), URL (anything you could possible want to do with one) and LTN12 (filters, sinks, sources and pumps) modules can be very handy.

The library is available under the same terms and conditions as the Lua language, the MIT license. The idea is that if you can use Lua in a project, you should also be able to use LuaSocket.
