I know that C++ should be first, but I still want to try and expand the idea of C# on the nspire if it is humanly possible

It is certainly possible; however, its uses probably will be limited by the overhead of the interpreter.
It is *much* harder than C++. We already have a C++ cross-compiler, but there isn't a complete C# interpreter for ARM devices yet.

Bwang, good point, perhaps I could work with someone to port C# to the nspire....

out of curiosity, what would it take to build your own interpreter?

Not much, (imo).  In TI-Basic, an interpreter is as easy as:
Code: [Select]
"sub(str1,A,1->v
For(A,1,Length(str1
If v="command
Do stuff
If v="other command
Do other stuff
End
It would be about the same thing in C, might be fun to write if I knew how to access files on the calc.  I'd be happy to help you :)  (although other people would probably be better suited to the job)

of cousre, I wish TI-Basic had a To.Upper method :P

and thats interesting player, if we get further on this, I would love to work with you

I've been thinking about doing this, although it would probably be easier to port one.
_player1537, you access files by using filesize() (in the utils.h in skeleton.zip attached to the first post on the Routines thread) to get the size, the fread to read it into an array, like so:
Code: [Select]
FILE* f;
int fsize;
char* buf;
f = fread("/documents/Examples/thegame.tns");
fsize = filesize(f);
buf = (char*) malloc(fsize);
fread(buf, 1, fsize, f);
close(f);

Isn't c++ backwrds compatible with C code?
C++ is partially backwards-compatible with C (in various situations, e.g. some forms of typecasts, a C++ compiler will refuse code that is valid in C), and it is interoperable with C (within a given ABI scheme, that is) through "extern C { }" blocks.

I'm sure these were typos, but those should be fopen and fclose. Just so nobody gets confused :)

*facepalm* C# isn't interpreted...
At compile-time, it is compiled almost all the way.  Then, at run-time, it is JIT compiled (Just-In-Time) the rest of the way.  You can do the second step whenever you like and save the binary, thus making it not interpreted.
I have been planning for a while to make a .NET Framework-like thing and object oriented C# based language for the TI-83+/84+ (SE).

I assume that would be for KnightOS?

I wonder how easy it would be? Would it take like most of the calc memory?

Also no facepalming at people who are learning Sir. We do not want to lose members.

Microsoft made a .NET Compact Framework made to fit on most handheld devices with low disk space, such as phones running Windows CE. According to Wikipedia, it takes up 12 MB, which could fit on the nspire. There is also the .NET Micro Framework, which takes no more than 300KB of space and doesn't need an OS to run, it could even fit on a TI-84. So C# on the nspire should be possible with at least the .NET Micro Framework. Plus the fact Microsoft announced they will release the .NET Micro Framework 4.0 source code under an Apache License 2.0, it would be awesome if someone manages to run some C# on the nspire.

Mhmm, if it's 12 MB and cannot be shrinked in size, it would take pretty much all of the Nspire mem or close. I think the original OS 1.1 leaves you with like 14-17 MB free x.x

Will the .NET Micro Framework thing be smaller?

EDIT: Nvm checked Wikipedia and it seems pretty small for the Nspire.

SirCmpwn, I already mentioned early in this topic that there are JITs in the .NET interpreters ;)

Lionel, okay.  I'm just pointing out that it doesn't have to be interpreted.
DJ, probably, KOS is better suited to object oriented programming.
