I never was a fan of some file transfer programs, and I was annoyed with the range limitations of modems. I heard about the string metatable hack, and decided to test my programming skills (sort of).

mSend v1.2

modemless, infinite range

file transfer program


Install v1.1:

pastebin get 0FW50ZZ1 msend

Syntax:

msend send [filename] <target_id>
msend receive <filter_id>
msend update
msend about

Features:

-The ability to quickly transfer single files across any distance and across worlds

-No dependence on rednet modems

-Everything is in one file

-Argument to automatically update


Notes:

-If you want to send a file to anyone listening or recieve a file from anyone, ignore the ID or set it to -1.

-All global variables are set to nil 0.1 seconds after the send command.

-This has been patched for ComputerCraft 1.7x and later. Booooooo.


Changelog:

1.0:
		+Initial release (2/5/2015)
1.1:
	+Added ID filtering arguments
1.2:
	+Added update option
	*Fixed overwriting issue


Let me know if there are any problems. It works perfect for me. At least, in CC 1.63.

Received an error on the receiving computer, nil on line six. I was using CCEmuRedux, I think it may be due to the ComputerCraft version it uses.

I tested it ingame, not in an emulator. I'll try to test it in CCEmuRedux, but try it ingame. I got it to work on LuaLand.

EDIT in 2018: oh lualand how I loved you

It probably wasn't. At the time of your comment, I was still making msend, and that's when you got the receive error, which is what I was trying to fix. It should work now!

Also, thanks for putting msend on LuaLand as a default application!

this will go one of two ways:
1:
The mods will get mad at you for exploiting a bug
2:
The mods will think it's awesome you've exploited a bug to do something cool

Well, it appears that the latest beta has patched this exploit, as was to be expected really.

aaaaand it's been patched
pretty hilarious to think all this time we where building huge pillars with rednet servers and having to go to near someone lives to play a multiplayer when we could do it with a simple hack for free.
