<h2 id="whatis">What is LuaSocket?</h2>
|
|
|
|
<p>
|
|
LuaSocket is a <a href="http://www.lua.org">Lua</a> 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.
|
|
</p>
|
|
|
|
<p>
|
|
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. </p>
|
|
|
|
<p>
|
|
Among the support modules, the most commonly used implement the
|
|
<a href="smtp.html">SMTP</a>
|
|
(sending e-mails),
|
|
<a href="http.html">HTTP</a>
|
|
(WWW access) and
|
|
<a href="ftp.html">FTP</a>
|
|
(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
|
|
<a href="mime.html">MIME</a> (common encodings),
|
|
<a href="url.html">URL</a>
|
|
(anything you could possible want to do with one) and
|
|
<a href="ltn12.html">LTN12</a>
|
|
(filters, sinks, sources and pumps) modules can be very handy.
|
|
</p>
|
|
|
|
<p>
|
|
The library is available under the same
|
|
<a href="http://www.lua.org/copyright.html">
|
|
terms and conditions</a> 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.

<h2 id="download">Download</h2>
|

|
|
<p>
|
|
LuaSocket version 3.0-rc1 is now available for download!
|
|
It is compatible with Lua 5.1 and 5.2, and has
|
|
been tested on Windows XP, Linux, and Mac OS X. Chances
|
|
are it works well on most UNIX distributions and Windows flavors.
|
|
</p>
|
|
|
|
<p>
|
|
The current version of the library can be found at
|
|
the <a href="https://github.com/lunarmodules/luasocket">LuaSocket
|
|
project page</a> on GitHub. Besides the full C and Lua source code
|
|
for the library, the distribution contains several examples,
|
|
this user's manual and basic test procedures.
|
|
</p>
|
|
|
|
<p> Take a look at the <a
|
|
href="installation.html">installation</a> section of the
|
|
manual to find out how to properly install the library.

<h2 id="thanks">Special thanks</h2>

<p>
|
|
This marks the first release of LuaSocket that
|
|
wholeheartedly embraces the open-source development
|
|
philosophy. After a long hiatus, Matthew Wild finally
|
|
convinced me it was time for a release including IPv6 and
|
|
Lua 5.2 support. It was more work than we anticipated.
|
|
Special thanks to Sam Roberts, Florian Zeitz, and Paul
|
|
Aurich, Liam Devine, Alexey Melnichuk, and everybody else
|
|
that has helped bring this library back to life.
