<h2 id=whatis>What is LuaSocket?</h2>
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
LuaSocket is a <a href="http://www.lua.org">Lua</a> extension library
|
2004-06-16 06:28:21 +02:00
|
|
|
that is composed by two parts: a C core that provides support for the TCP
|
2003-08-31 03:00:15 +02:00
|
|
|
and UDP transport layers, and a set of Lua modules that add support for
|
2004-06-16 06:28:21 +02:00
|
|
|
functionality commonly needed by applications that deal with the Internet.
|
2003-08-31 03:00:15 +02:00
|
|
|
</p>
|
|
|
|
|
|
|
|
|
|
<p>
|
2004-06-16 06:28:21 +02:00
|
|
|
The core support has been implemented so that it is both efficient and
|
|
|
|
|
simple to use. The core can be used by any Lua application once it has
|
2004-06-16 01:00:56 +02:00
|
|
|
been properly initialized by the interpreter running the
|
2003-08-31 03:00:15 +02:00
|
|
|
Lua application. The code has been tested and runs well on several Windows
|
|
|
|
|
and Unix platforms.
|
|
|
|
|
</p>
|
|
|
|
|
|
2004-06-16 06:28:21 +02:00
|
|
|
<p>
|
2004-06-16 22:41:03 +02:00
|
|
|
The most used modules 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
|
2004-06-16 06:28:21 +02:00
|
|
|
protocols. These provide a very natural and generic interface to the e
|
|
|
|
|
functionality covered by the protocols.
|
2004-06-16 22:41:03 +02:00
|
|
|
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.

|
|
2003-08-31 03:00:15 +02:00
|
|
|
<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.

LuaSocket version 2.0 beta2 is now available for download! It is
|
2003-08-31 03:00:15 +02:00
|
|
|
compatible with Lua 5.0 and has been tested on
|
|
|
|
|
Windows XP, Linux, and Mac OS X.

|
|
</p>
|

The library can be downloaded in source code from the following links:

I am also providing PC Win32 binaries for those that want to give
|
2003-08-31 03:00:15 +02:00
|
|
|
LuaSocket a quick try:
|
|
|
|
|
</p>
|
|
|
|
|
|
|
|
|
|
<blockquote>

|
|
|
<p>
|
2004-06-18 23:41:51 +02:00
|
|
|
The quick and dirty way to use these binaries is to unpack everything into a
|
|
|
|
|
directory, say <tt>c:\luasocket</tt> (include all Lua files from the
|
|
|
|
|
LuaSocket distrbitution in the same directory too!).
|
|
|
|
|
Then set <tt>LUA_INIT</tt> to load the <tt>lua.lua</tt> helper file:
|
2003-08-31 03:00:15 +02:00
|
|
|
</p>
|
|
|
|
|
|
2004-06-18 23:41:51 +02:00
|
|
|
<pre class=example>
|
|
|
|
|
c:\luasocket\> set LUA_INIT=@lua.lua
|
|
|
|
|
</pre>
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
From that directory, you can then run the interpreter and it should find all
|
|
|
|
|
files it needs. To download this manual page from the Internet, for example,
|
|
|
|
|
do the following:

|
|

Throughout LuaSocket's history, many people gave suggestions that helped
|
|
|
|
|
improve it. For that, I thank the Lua community.
|
2004-02-04 15:29:11 +01:00
|
|
|
Special thanks go to
|
2004-06-16 06:28:21 +02:00
|
|
|
David Burgess, who has helped push the library to a new level of quality and
|
2004-06-16 01:00:56 +02:00
|
|
|
from whom I have learned a lot of stuff that doesn't show up in RFCs.
|
2004-02-04 15:29:11 +01:00
|
|
|
Special thanks also to Carlos Cassino, who played a big part in the
|
2004-07-26 06:04:04 +02:00
|
|
|
extensible design seen in the C core of LuaSocket 2.0. Recently, Mike Pall
|
|
|
|
|
has been helping a lot too! Thanks to you all!

|
|
|
simple work around);
|
|
|
|
|
<li> UDP has a reasonable maximum datagram size (8k);
|
2004-07-26 06:04:04 +02:00

non-blocking);

|
|
|
|
<li> <b><tt>Send</tt> doesn't support multiple arguments anymore</b>;

|
to be sent (good for non-blocking);
|
|
|
|
|
<li> Fixed bug that caused select return tables not to be associative
|
|
|
|
|
on windows;
|
2004-07-26 07:19:47 +02:00
|
|
|
<li> Should compile with g++;

|
|
|

|
|
|
<li> SMTP/FTP/HTTP fail gracefully;
|
|

|
|
|
|
|
<li> Fixed bug that didn't set accepted sockets as non-blocking
|
|
|
|
|
<li> <b>New timming functions <tt>sleep</tt> and <tt>gettime</tt> have
|
|
|
|
|
higher resolution and no wrap around problems</b>;
|
|
|
|
|
<li> Bug fixes in the manual;
|
|
|
|
|
<li> Fixed bug of missing cast in <tt>getfd</tt>.
