Nspire I/O - Now with C++ support
« on: November 19, 2013, 03:30:07 pm »
After ExtendeD added support for C++ to Ndless some months ago, I have added experimental C++ support to Nspire I/O now.
It has an iostream-like interface, so it should be easy to use (at least I hope it is :P )

The obligatory "Hello World":
Code: [Select]
#include <nspireio/console.hpp>

int main(void)
{
  nio::console c;
  c << "Hello World!" << nio::endl;

  return 0;
}

A more complete demo can be found here.
The output of that demo is attached below.

The source code can be found on Github and in the attached zip file (that contains the compiled library file and demos as well).

Good to hear. :) I wonder if the PRIZM version has been cancelled or if it's still in development btw?
In case you are wondering where I went, I left Omni back in 2015 to form CodeWalrus due to various reasons explained back then, but I stopped calc dev in 2016 and am now mostly active on the CW Discord server at https://discord.gg/cuZcfcF

I think I can call it an indefinite hiatus. I might pick it back up someday, but last time I tried, everything I compiled (NspireIO or not) crashed. Probably my installation of PrizmSDK. Anyway, I wonder if C++ support won't mess that up, since the Prizm have none of it...

That's great to hear. Did you solve the inheritance issues that you posted about in another thread?

Yup. I tried it with another approach without multiple inheritance and for now, everything seems to work more or less :P

Hi ,
every time i pass some variables to nspireio the programm crahes if i try to execute it.
I've no idea whats wrong.
I basicely only modified the exampel to display a cstring and a string. but it doesn't
work...
The programm crahes if i pass the variables with << operator.
Code: [Select]
#include <nspireio/console.hpp>
#include <nspireio/uart.hpp>
#include <string.h>
#include <string>
#include <iostream>

#ifndef NIO_TEST_UART
#define NIO_TEST_UART 0
#endif

using namespace std;
using namespace nio;

int main(void)
{
clrscr();
#if NIO_TEST_UART == 1
nio::uart u;
#endif
nio::console c;

int num = 123;
char cString[] = "Test";
string cppString = "Text";

c.foreground_color(COLOR_BLACK);
c << cString << endl;
c << cppString.c_str() << endl;

wait_key_pressed();
return 0;
}

Does anyone have a clue?
Thanks

Hi Silversircel,

There isn't a port of the Standard library for the calculator.  Here is a link to the syscalls: http://hackspire.unsads.com/wiki/index.php/Syscalls

I tend to use the char pointer (char*) and strcpy, strcat, etc.  Hope that helps!

Silversircel doesn't use the C standard library in his/her program.

Also, there's newlib, and many of the functions in it work.

Hey Legimet,

Oh?  I see the user does all of these:
#include <string>
using namespace std;
string cppString = "Text";

As I understand newlib (https://sourceware.org/newlib/libc.html#Strings) it gives you a lot but this user is using the C++ string header file; and I think the C++ string class can throw exceptions and other things.  I didn't think the C++ std::string class would work at all.  But I'll give it a try when I get the chance! :)

Sorry if I wasn't accurate!  Have a great day!
