Darn this is epic ExtendeD. A lot of people liked to program on-calc when they did 83+ stuff. I bet this will be appreciated by many Nspire owners too. shocked

I hope if ndless 3 comes out we can have a robust editor with a compiler.

Even if it's not a compiler, it looks like one...
How should we call that ? an "encryptor" ?

I think he means that if Ndless 3 comes it'd be good to have an on-calc text editor with a LUA>TNS Converter. Keep it simple Smiley

I was talking of the tool which produces TNS files from LUA code.
I don't really know what a shell is, but I think it's something different. (The interpretor is a shell, isn't it ?)

Huge up, sorry Undecided

I'm having trouble with OCLua : why can't I use a for loop which runs more than 128 times ?

This code brings the calc into an infinite loop :
Code: Select All | Copy To Clipboard

1
2
for i = 0, 128 do
end
And this works fine :
Code: Select All | Copy To Clipboard

1
2
for i = 0, 127 do
end

I haven't tried your code, but I assume you put that in on.paint .
Probably what is happening is that on.paint get's called again (sometimes it does this when execution time is a bit too long), causing it too loop constantly.
But that's just a theory.

Could you post more of the code ?

Also, I'm not sure about Jim's theory - well I haven't found myself in such case before. but maybe with timers and stuff it may happen... weird though...

Here is the code which doesn't work for me.

In fact, once I try the code I just posted, it works Huh? but just try the one I joined (it's the page 3).

Also, do you know a way to get text from a *.tns ?

Copying and pasting some text might work, as would accessing TI-BASIC variables... but without external help, TI's proprietary Lua, which does not have io.* and os.* functions (i.e., among other limitations and incompatibilities with standard Lua, no external file access) cannot get text from a .tns.

I believe he's talking about the OcLua's text in page 2 which is a Notes page. So not-related with TI's Nspire-Lua. But still, it's a closed format.

The "only" easy way is to open it with the computer software. Then copy/paste it wherever you want it.


Anyway, about your script : no problems for me for any of your codes...
(Also, remember to put the least possible code (only the final graphics/screen drawing -related things) in the paint method since it's going to get called quite often and you don't want it to slow the rest Smiley
