Greetings.

imagine this code...

void c()
{
  char [] t = args[0];
}
void main(char[][] args)
{
  int i = 1;
}

How can I make args global?

thanks,

jose

import core.runtime;

void c()
{
    char[] t = Runtime.args[0].dup;
}

void main(char[][] args)
{
    int i = 1;
}

.dup is necessary since Runtime keeps the args as a string[] and not a char[][].

First, the general discouragement: Avoid global data. :)

You can initialize a global variable upon entering main:

import std.stdio;

string[] g_args;

void foo()
{
     writeln("Program name: ", g_args[0]);
}

void main(string[] args)
{
     g_args = args;

     foo();
}

Technically that's a module variable. There's no such thing as global
scope in D. :-)

In D, technically the only way is to use Runtime, as Andrej mentioned.

As an aside, it is worth noting there is no global scope in D, module
is as high as you go.
