Article: Using LuaSockets

[Brett]

See the attached document for full details.

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."

In other words, the LuaSocket library allows you to do both low-level and high-level TCP and UDP communication from AutoPlay Media Studio 6.0 projects.

Wow! that's great! :yes

Thanks Brett, that' sure to come in handy.

Brett. . . what happen to the bar? (as in, "raising the bar"). We are way beyound that!

Thanks for sharing! It might be another day in the code matrix for you... but it's a code maze for the rest of us (if I may be so bold).

:yes

[Worm]

Too cool! Simply too cool!

Ditto * 4 ... :)

Does this mean that there will be inter-app socket communications?

[Intrigued]

Brett, I noticed this in your documentation(again, thanks for sharing), FWIW:

package.cpath=_SourceFolder.."\\AutoPlay\\Scripts\\?.dll;"

It looks like the semi-colon needs to be at the end?

I copied and pasted Brett's code and it worked fine. Seems to work either way.

[Intrigued]

Ya, just looking for clarification. (hence the question mark at the end).

:yes

Actually the internal semi-colon is by design. That path allows for multiple search locations separated by semi-colons (even though I only specified one so it will work either way).

As far as I can tell that should be possible. The LuaSocket library allows you to open sockets and send/recieve on them.

Ah, I gotcha. I thought I had seen you post something like this before and I was wondering....

Hi Guys,

Thank you guys for all of your great help. I am trying so hard to write two programs that will communicate with each other. The server where you can click on a button and it will put text in a text box on the client, also it would play a simple wav. This is a sort of "notification" software, where the server can send a preset message to the client over a network. If anyone knows how to use luasocket, or has any ideas, please please let me know. Thanks again.

You almost killed me with this one...

Is this download still available - you say "Then go to the Download page and download the “PC Win32 binaries”. Can't find “PC Win32 binaries” with the content you describe in your .pdf :huh

[nrgyzer]

Yes, I'am too. I downloaded the file, but I only have two folders (lib and lua). The folder lib are only contains two folders with a core.dll. But the lua folder contains the folder socket (contains the following files: ftp.lua, http.lua, smtp.lua, tp.lua, url.lua) and the files ltn12.lua, mime.lua, socket.lua. But where is the lua.exe, compat-5.1.lua, liblua.dll and other files? I can't find this files in my downloaded package.

Hey guys, ok, I have been working on this off and on for almost a year now, as you can tell from my earlier post, and I still have yet to figure this out. Is there ANYONE out there that can help me with this??? Thanks. I guess I am not a natural coder, lol.

[Tek]

Yeah I'm stuck in the same boat. I know the vast majority of users here don't use LuaSocket but I have been trying to learn it anyways. :) Unfortunately, time is always my worst enemy.
