#159027 [1.6.4] TechValley ComputerCraft Server

Posted by Orwell on 02 January 2014 - 02:13 PM in Servers

The server seems to be down, I hope this is temporary...

#158651 [1.6.4] TechValley ComputerCraft Server

Posted by Orwell on 31 December 2013 - 09:30 AM in Servers

Hi, I'm interested in playing ComputerCraft again and I love the charm of a pure CC-server.

It would be nice to be added to your whitelist.

That doesn't seem to be entirely true, 'nil or nil' yields nil. Where nil does make a difference is in the case of 'false or nil':

x = 1==2
y = x --# or nil

Of course, in the case of the golf submission, b is only used in the conditional statement 'if b then' so it wouldn't matter in this particular example.
But you are right about it having a use. I didn't realize that.

NOTE: if there is any data in b then the coordinates are assumed global. leave b out of the function if the coordinates are relative to the turtle.

if b then
c,d,e = gps.locate()

(z < 0) and t.turnLeft() or t.turnRight()
(z < 0) and for a = -1, z -1 do f() end or for a = 1, z do f() end
end
end

total length: 447 characters without whitespace

this program won't run it's only a function, You need the interface code for parsing the command line. it's character count will be more than 447. At minimum you will need this at the end of the program to make it functional:

a={...}
goto(a[1],a[2],a[3],a[4] or nil)

Also there is an error on line 1 of your function() you have 'B' and not 'b'. Remember variables are case sensitive. With my addition to make your goto function an actual program for the competition valid your total character count comes to 476!

I do agree with theoriginalbit on this matter. But besides that, you only need to add 9 characters if you insist on it being a program:

goto(...)

This keeps the count at 456 which is a lot less than your addition.

And why would you ever do this?

a[4] or nil

It's like doing '1+0'.

What exact command you're running? I might be able to help you better that way. The trick is to use the full path name in between quotes. E.g.:

In my experience, it's very difficult to use. If you like using a tablet-like interface on a desktop, then by all means, go with Ubuntu. If you'd rather use a traditional desktop, use Linux Mint where at least you get your choice of window managers.

Either way, I don't see why you'd rather go with Ubuntu when you can get Linux Mint. Like I said before, Linux Mint is a fork off of Ubuntu to begin with, so they're able to use mostly the same packages are each other (except maybe in some rare, freak case). Linux Mint has a bit more freedom with it.

Also, wasn't Ubuntu adding in like advertisements and stuff into Unity? I could have sworn that they were sending unencrypted searches to Amazon or something like that when you searched your own computer/desktop.

The only tablet kinda thing on ubuntu is the sidebar. And I simply run the Cinnamon window manager on my Ubuntu installation, so I have no trouble with that. I wouldn't stay away from Ubuntu for unity only, there are much more important differences between distributions.

This is a updated version of yours:

local config = fs.open("file", "r")
local sFile = config.readAll()
local something = sFile:gmatch("something = (%S+)")() -- %S matches every character except for space characters
print(something or "No match has been found!")

I would say that you would still want to for loop so that it gets the last copy of the match, not the first, or of course you should be able to use the `$` in the pattern.

Indeed. I understood from the OP that he doesn't really have a use for this but rather wants to know what's going on. So I tried breaking it down a little and I left some parts out.

#125381 Regex description

Posted by Orwell on 11 June 2013 - 06:44 AM in Ask a Pro

It will find a portion in the file that reads 'something = abcdef' where abcdef is any sequency of characters with a length greater than one. The brackets mean that only the abcdef part will be extracted and that the function will only return that value. So for each instance of 'something = xxsomestringxx', the variable 'a' will equal 'xxsomestringxx'. In each iteration of the loop a will be assigned to the variable something. So eventually something will equal the value from the last match in the file and will be nil if no match has been found.

Edit:
LBP is right, there are some other issues with the code. You don't need to loop through the lines of the file and obviously you need to pass the content from the file to string.gmatch. This is a updated version of yours:

local config = fs.open("file", "r")
local sFile = config.readAll()
local something = sFile:gmatch("something = (%S+)")() -- %S matches every character except for space characters
print(something or "No match has been found!")

Now if you have a file on your computer named 'file' that has this content:

This is a file with some stuff in.
foo = bar
something = foobar
me ~= you

There is nothinf wrong with pingeleon's solution, however, I wanted to add that it is hard to to make it possible without having two computers.

Also, you are quoting me lately a lo, may I ask why?

No idea, probably same time zone, so your posts are a lot at the top for me? I really didn't notice, I've been posting more often lately so maybe other people are thinking the same.

No need to feel targetted, it's not like that.

Anyway, it's equally secure to use encryption between the two computers (probably even more secure). And if securing files is all you want you really don't need to change anything to api methods or anything.

Let's say you want to send a file from client to server. Then you encrypt it on the client using a password as the key, next send it over rednet to the server. The server stores it encrypted. Then the client can ask to fetch it again, it will still be sent encrypted over rednet. Then the client will be prompted for the password so the file can be decrypted again.

Yeah, except

They're pretty distinguishable. Plus, when it sends a message, it can return to the server the computer's coordinates. That can also help in tracking who is using the computer. At least maybe. Besides it would be no different than spamming with the current block, would it?

Plus, I don't know if it already exists, but there could be a block limit, (say 64 or something) so it would only bother people within a 64 block radius.

there is a block limit set in one of the parameters of the say command, but if you omit the parameter, then it is an infinite range (I think). and since coding is so epic, you could probably prevent the computer taking even the resemblance of a players name.

My point is that it's not enough to make it distinguishable, but it should also be obvious to newbies that this is a program talking and not a player. And spamming would be totally different than framing someone else for something. Anyway, block limit sounds like a decent thing to make configurable by default (in the server config that is).

Huh, so what did the 9 I change affect? xD My turtle seems to be running fine right now. I'll go stab it with a knife and give it a new code. I wish I could delete programs from it's list.

In command-line:

rm programName

You changed the code for a list in the NBT data. But I don't think the schematic files use lists, so you had luck.

Oh yeah, what I meant to say earlier. If there are more than 16 materials needed.. Just returning to a chest for the next materials wouldn't be so handy because you can't know what item is which. The automatic refill would work because the turtle can always keep one of each item, thus sucked items from the chest would append to the allready loaded items.

The issue is that it makes spoofing of other player's names possible. You don't want a computer be spamming the chat in the name of the owner, do you?

Fair enough. However it would have the @ sign in front of it and be italicized. So it would obviously not be mistaken for the real owner, or whoever. I don't really see it as THAT big of an issue.

We'll see when you get banned from a server because I start trolling like hell with your username.

The prefix idea is ok. It might be better to make it even more obvious for the more naive people out there, but it could work.

One issue I had when I downloaded a schematic, is it had like 40 different block types in it so I couldn't do that with the limited 16 slots.

Maybe something that will attempt to place all blocks in a level, if some weren't there it can pull from a chest what it needed replacing slots and such? THough that's getting much more complex I bet.

http://pastebin.com/789upkpX - is this correct? For the use of 16 slots. I don't know programming of any kind so I wouldn't know if I was right or not. I changed 2 9s into 16 and left the others alone since they didn't seem to be part of the code, were more like block IDs.

Oh, I didn't know that. No you change one 9 too many (it was a code from the NBT format) and you missed a 'n>0 and n<10' which checked that the slot was in between 0 and 10.
Here is the a correct adaption: http://pastebin.com/RAztRaLH

Yes, you can use it with the printer. Usage is in the OP. If you can't read that, a video won't do you much good either.
