Question

A perl script which would include different modules for both Windows and Linux, In order to make it cross-platform, I want someway to implement it, just like in C++:

#if _WIN32
//...
#else
//...
#endif

Answer 1

if, $^O:

use if $^O eq 'MSWin32', Win32::Console::ANSI::;

---

Alternatively,

use Win32::Console::ANSI ();

is equivalent to

BEGIN {
    require Win32::Console::ANSI;
}

so you could also use

BEGIN {
    require Win32::Console::ANSI
        if $^O eq 'MSWin32';
}
