making args global

[jicman]

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

I'm assuming you're using D2.

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();
}

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.

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