So I'm reading this tut from Ali :)

And we I got to this part :

A code example. http://pastebin.com/ESeL7dfH

But I want to declare this functions "print" outside of the file and call the file to be loaded by the compiler. So I can use the same solution in various program without having to copy paste it to each one.

Thanks you for your attention.

Main file :
-------------------------------------
import std.stdio;
import print;
void main()
{
    int[] numbers;

    int count;
    write("How many numbers are you going to enter? ");
    readf(" %s", &count);

    // Read the numbers
    foreach (i; 0 .. count) {
        int number;
        write("Number ", i, "? ");
        readf(" %s", &number);

        numbers ~= number;
    }

    // Print the numbers
    writeln("Before sorting:");
    print(numbers);

    numbers.sort;

    // Print the numbers
    writeln("After sorting:");
    print(numbers);
}
-----------------------------------------------
Library file :
-----------------------------------------------

void print(int[] slice)
{
    foreach (i, element; slice) {
        writefln("%3s:%5s", i, element);
    }
}
----------------------------------------------

I just readhow to do it down on the list of tuts.

I did : dmd primes.d ./prime.d, and done program ran perfectly

first way - put this "print" function into its own module, compile your "client" program simply adding print module in source list.

example: "dmd yourmain.d print.d"

(this way you actually just adding all code from "print" module to your program)



second way(phobos actually using this) - put your "print" in its own module and compile it as static library. then when compiling your client program link with this lib and add import search path with -I to location where print can be found.

example: "dmd print.d -lib && dmd yourmain.d print.lib"

(with this way only used stuff gets imported(function/types/etc. definitions), and then linked at compile time with static lib which contains actual compiled code for that function).
