This looks really interesting!
Can you add a pastebin link to your post, so i can download it directly to the command computer and/or the turtles please?

because every user of computercraft wants to program an encrypted connection for every door program they write

Can we get a modem type that returns the java side computer id and not the lua one?

It would be really useful for bank servers or door locks or shops.

Aditionally this would make long range modems a bit less over powerd since the secure modem would only return the id of the last repeater. And because of that there would be more than one long range modem per world.

There you go: http://pastebin.com/zeYgY0NF

Run "pastebin run zeYgY0NF" on a command computer -> admin bow

Can you replace

function forward()
turtle.forward()

with

function forward()
repeat until turtle.forward()

and same with up and down? that would make the program a lot more robust if something stands in its way.
the line

turtle.select(3)

is no longer nessary because of the selectBlock method and only causes the turtle slots index to flicker after every move.

I love running through your mazes and i have created quite a few of them in my world

placing the block against the turtle should be the first choice and only choice in my optionion, too.

A useful trick in lua:
local vowels = {u=true,

local vowels = {
a=true,
e=true,
i=true,
o=true,
u=true}
if vowels[ string.lower( result[1] ) ] then
--this is a vowel
end

If you use the vowel as a key, you dont need a for loop.

This is a very simple program which generates a minesweeper game in your wolrd. Each spot is 3*3 and 4 blocks high and can be activated with the stone plate on top. The number on blocks pushed up by the pistons indicate the number of surrounding mines.

pastebin get rg3Bx79Z minesweeper
minesweeper [cells in x-dir] [cells in z-dir] [mines] [min x corner of board] [min y] [min z]

Fixed that. It is now one block above the computer.

Bomb Bloke, on 11 December 2015 - 01:57 AM, said:

Yeah, the wiring is a big difficult, if there is only a 3*2*3 area to work with. Because of that only the indicator blocks on the side of the next spots are activates (only redstone dust and no redstone repeaters are used)

Bomb Bloke, on 11 December 2015 - 01:57 AM, said:

There could be command blocks under the pressure plates which triggers the spot action like displaying a number with /title, /tellraw or /setblock sign.

But that would not be survival like and would not be able to explode at all.
The disadvantage with cables is that there can be computercraft without the cables and that the computer must not restart for the game to work...

Like this?

I tested it with a 1100 line program and it took like 3 seconds allready. It may be a bit slow on large files.

SquidDev, on 03 December 2015 - 08:53 PM, said:

Yeah, i looked at your program before i started programming this, but i think you are trying to inject code after the conversion to bytecode, but i think the upvalues might become a problem there, am i wrong?
If it is possible, there would not be any need to worry about syntax.

SquidDev, on 03 December 2015 - 08:53 PM, said:

That is very true, using patterns sure is flakey. Atm my debugger is not able to handle quite a few unusual snytaxes which lua allowes. I will look into your parser, but replacing is for the normal stuff easier.

I tried to add it to the LuaIDE on gravitystores github, but i could not get it to work...

Is your cc luac version uploaded somewhere?

SquidDev, on 23 May 2015 - 05:25 PM, said:

Well, good news: It is possible using code injection.

This is an advanced lua debugger without using the debug api.

Features:

• stepping through your program while seeing the source
  
• show local and globals variables
  
• show which functions have been called (f4)
  
• set breakpoint and run until you reach them
  
• step-into own function and step-over
  
• stepping backwards lightweight (undoing changed)
  
• stepping backwards heavyweight (replay the program to last point)
  
• stops on lines which throw errors (so you can see the locals or step back)
  
• reverses some functions (like the turtle ones)
  
• stop the program while it is running (f6 in source window)
  
• lua prompt in the middle of the program execution (f10)

Is your turtle trying to build a house, but its allways taking the wrong turn at some point? Then this is perfect for you! You can step through your program (with f6) until it does the wrong turn and then you know excatly which line caused it! From there on you could even step backwards in your program (with f5) until the whole house is gone again to start over again! You can step into every function of your program, but be careful because you could even step into poop!

local function poop()
end

Screenshots:

Technical details:
Every start of a line gets a _lbpcf() call (line breakpoint call function). It prints the source and waits for user input. The local statements get replaced by _cnlv (create new local variable) so that they can be handled with the __index-metamethod of the environment. _bscf and _becf (block start/end call function) handle the scoping. For how the modified program look, see the .crash file that is created.


System requirements:
Required:

• CraftOS 1.74 (might work for lower versions)
  
• >0 tps

Recommended:

• Advanced Computer with CraftOS 1.74
  
• 20 tps

Installation:

pastebin get LdKK3BTE

Updated to version 1.1

Added inline lua prompt (f10)
stopping while running on advanced computers (f6)
and bug fixes

"28 seconds [...] for Yueliang 0.1.0. (Native C is virtually instantaneous, so a comparison is pointless, really.)"
That sure is slow

SquidDev, on 03 December 2015 - 09:26 PM, said:

That would be so slow Well, it would not matter for a debugger.

To prevent the keywords in strings problem, i could simply remove all strings with something like

gsub('"(.-)"',function(t) table.insert(strings,t) end)

and put them back after the modifying. Once i can think of a way to do that with both " and '

Ok, moving entities does now work, but there aren't any animations for armorstands yet.

Ok, i'll change that back then.

Bomb Bloke, on 15 December 2015 - 02:26 PM, said:

@e[type=Pig,c=1]

Asking for a selcetor was my first choice because it is by far the most flexible way to select a entity and the ability to seize a creeper running by and let him do your work is quite satisfying. Only asking for the type may indeed be a bit easier for the user.

Wojbie, on 15 December 2015 - 02:36 PM, said:

With or without armor?
I am going to add that as a default.

Updated.
Window is top left again
Only asking for type instead of selector now.
And default is an ArmorStand with a turtle on its head.

Bomb Bloke, on 12 December 2015 - 01:50 AM, said:

Luckily 1.8 does offer a method like that: /blockdata ~ ~ ~ {}
It returns false, a complain that nothing has changed and the nbt tag.

Since 1.8 has a /entitydata: Can you modify your api so that the turtle can be represented by any mob (with {NoAI:1b} ) and Armorstands (with {NoGravity:1b} )? Or allow me to modify your script and link it from here?
With the ArmorStand Pose tag it would even be possible to have an animated turtle/player like thing.

Now for 1.75
