I think I know what modulus does now!
Created some sort of a guide here: http://ourl.ca/15687.new#new

Now, I did find a definition for .. but still have little idea what it means

Concatenates two strings (joins them together into a single one)

Edit: So for the following code:

Code: [Select]

local str = Moves .. " moves"
Moves is a variable that contains the number of times you've moved a piece
" moves" is a string & remains the same

Let say Moves = 200, so the string is equivalent to:
"200 moves"

Ah ok thanks for the info. I hope TI won't start breaking stuff in the future, like Notch is doing with Minecraft now

(or what TI did with OS 2.53MP)

Well, I can assure you TI is did much work to keep <3.1 Lua scripts work fine on 3.2. They are clearly dedicated to this, so I wouldn't worry that much.

Exactly how would you create a batch file for Luna? I don't really know how to take arguments for .bat

Nice job with the 15-puzzle, no wonder it didn't work before.

Good luck with learning Lua!

Why do you need a bat file ?

Luna just works like that :

luna[.exe] source.lua output.tns

cyanophycean314 · « **Reply #21 on:** March 28, 2012, 09:49:41 pm »

Well, it'd be a lot easier if you don't have to open command prompt and type it in every time. Typing it in every time is slow... I run nspire_emu with a .bat too!

I had an answer in quick reply ready to go but then I refreshed the page

(This reply isn't as good as my original one)
With cmd you'd have to navigate to the particular folder every time just to run Luna! I do not want to do that!
A slightly quicker way is to Shift +Click the folder but you'd have to go up a directory and still type in the stuff. A bit fiddly

So using a .bat file makes sense, in fact I can see no way of me using the cmd due to the fiddly methods above.

Here is the bat file code:

Code: [Select]

@echo off
set /p luafile= Type the lua filename (without extension):
set /p tnsfile= Type the tns filename (without extension):
luna.exe %luafile%.lua %tnsfile%.tns

@cyanophycean314 I used Levak's Batch File as a guide and just modified it to suit Lua! Though I don't completely get what "set /p" means

Just a few lines of code makes things much easier and logical

Thanks someone, I did see the word concatenates when I was searching and had no idea what it meant!

Hopefully, all the hassles so far to create Lua scripts won't exist anymore with the 3.2 Lua SDK

Jim Bauwens · « **Reply #24 on:** March 29, 2012, 02:02:50 pm »

Ha, I'll stilll use Luna+shellscripts+TiLP. Nothing beats that!
I have EEPro building integrated in my editor (geany), and with one press of a button it builds EEPro (which exists out of many seperate lua files) and uses TiLP to send it to my CX (or uses PCspire).
Just awesome

Indeed, +1 Jim.

Until TI makes portable, scriptable tools that work for all of Windows, MacOS X, Linux and some popular BSDs - i.e. certainly never - there's no way all hassles can disappear

Scriptability, and separation between GUI front-ends and worker backends with a CLI (or at the very least, libraries for encapsulating the worker backends), is a very important feature; the tools whose maintenance I have inherited are not scriptable enough (though TILP happens to be scriptable enough to fulfill Jim's use case, its CLI is very limited)...

Adriweb · « **Reply #26 on:** March 29, 2012, 06:08:42 pm »

Lionel, totally agreeing with you about Linux... (but it's great they at least have a Mac version working...)

What I mean by the hassles disappearing, is that with one-click too, you are able to update your code within TINCS, and it can't be faster i any other way.
But of course, jim's scripts are better for "building" and on-calc testing all in one click

Jonius7 · « **Reply #27 on:** April 04, 2012, 02:17:29 am »

Anyway good to see that we won't have to take to such measures of making Lua scripts run in the future and can even edit the file directly (which means even better than Oclua on calc!). But to get back on topic
I want to try and understand completely what Goplat's 15 puzzle means. I've already learnt quite a bit, let's see what else there is. I have commented on this within the code

Code: [Select]

function on.charIn(ch) --called when a character key is pressed
	if ch == "r" then --when r is pressed
		board = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 } --this is how you create arrays!
		-- Randomize
		local swaps = 0  -- a local variable (wonder why)
		for i = 1, 16 do   -- ah this is the For...To syntax in TI-84 and Casio basic and other stuff
			local j = math.random(i, 16)  -- local variable, random number from i to 16
			if i ~= j then  -- i not equal to j
				board[i], board[j] = board[j], board[i]     --swap number in position i and j?
				swaps = swaps + 1  --swaps number of turns
			end
			if board[i] == 16 then  --reach the end
				empty = i  
			end
		end

		-- If the number of swaps plus the number of empty-space movements is odd,
		-- then the puzzle is impossible, so do an impossible move to make it possible
		-- (exchange the space with a tile two squares away)
		if (swaps + (empty - 1) + math.floor((empty - 1) / 4)) % 2 == 1 then   -- not 100% how this works, I know this is a way to fix an impossible puzzle :P
			local i = (empty + 7) % 16 + 1
			board[empty] = board[i]
			empty = i
			board[empty] = 16
		end

		moves = 0
		platform.window:invalidate()  --force redraw of the screen calls on.paint(gc)
	end
end

on.charIn("r")

function on.paint(gc)
	local won = true
	for i, n in ipairs(board) do
		if n ~= 16 then
			local x = (platform.window:width() - 128) / 2 + 32*((i - 1) % 4)
			local y = (platform.window:height() - 128) / 2 + 32*math.floor((i - 1) / 4)
			gc:drawRect(x, y, 30, 30)
			gc:drawString(n, x + (30 - gc:getStringWidth(n)) / 2, y + 15, "middle")
		end
		won = (won and n == i)
	end

	local str = moves .. " moves"
	gc:drawString(str, (platform.window:width() - gc:getStringWidth(str)) / 2, 0, "top")
	if won then
		str = "You win! Press R to reset"
		gc:drawString(str, (platform.window:width() - gc:getStringWidth(str)) / 2, platform.window:height(), "bottom")
	end
end

function on.arrowKey(key)
	local dir
	if key == "left" and empty % 4 ~= 0 then
		dir = 1
	elseif key == "right" and empty % 4 ~= 1 then
		dir = -1
	elseif key == "up" and empty <= 12 then
		dir = 4
	elseif key == "down" and empty > 4 then
		dir = -4
	else
		return
	end
	board[empty] = board[empty + dir]
	empty = empty + dir
	board[empty] = 16
	moves = moves + 1
	platform.window:invalidate()
end
