Lua compatibility accross Nspire OSes
« on: April 16, 2011, 01:47:32 am »
I wonder if anyone managed to check if Lua was actually possible on older TI-Nspire OSes? Since programs like the periodic table have only been around for OS 3.0 and that these OSes are huge, I wasn't sure if anyone checked through the OS to see if that language was already present on older ones.

I also wonder if Lua programs for the Nspire will be compatible with the TI-Nspire CX?

Trying to open the periodic table document on OS 1.7.2741 CAS yielded a ~"you need a newer OS version to open this file" message. Two parts of the file can contain versioning information (both probably do, directly or indirectly):
* the "TIMLP0500" header of the file;
* the contents of the Document.xml part of the file (which is compressed with the unspecified "0D" compression method, available only through yet-undocumented fiddling on nspire_emu/Ncubate).

Ok, what about 2.0.1 and 2.1? What I am also curious about is if the interpreter is actually present in the OS. Maybe the file format won't be read, but the language is there?

No, it's not present.

I would assume so, since they even work in the computer software.

Who wants to undertake the task of making a Ndless-based port of Lua ? :D

Thanks for the info Goplat.

Lionel that would be nice indeed, so we could run Lua games on older OSes too. As nice as this language discovery is, it sucks that it only runs on an OS that may never get to see Ndless.

Oh, I see that the Nspire's Lua doesn't have "io" and "os" functions, i.e. it's effectively (and efficiently) watered down. Having a full-featured version of Lua would be an even more worthwhile goal, then.

I see. I hope they didn't water it down too much either.

After seeing "setColor" and "isColor" functions, I'm positive that Lua will work on the CX.

Once Ndless works on OS 3.0, enhancing the Lua API will be quite easy.

Hmm, like having asm inline? That would be awesome!

It does, it works on the CX emulator, so it really works.

I'm not upgrading to System 3 without Ndless. You just can't beat the good old Nintendo Game Boy emulator.
