Re: Dynamic Class Loading, Compilation, & Speed

[jdrago999]

Try this:

#!/usr/bin/perl -w

use strict;
use warnings 'all';

# ...later...

load_class("Some::Class");

sub load_class {
  my ($class) = @_;
  
  (my $file = "$class.pm") =~ s/::/\//g;
  unless( $INC{$file} ) {
    require $file;
    $class->import;
  }# end unless();
}# end load_class()

Just as use <ClassName> operates in compile-time, require operates in runtime without a string eval.

To finish the job, call import on the newly-loaded package and you're done.

Nitpick... to handle the equivalent of use Module qw(foo => 'bar'); -

# ...later...

load_class("Some::Class", @load_args);

sub load_class {
  my $class = shift;
  
  (my $file = "$class.pm") =~ s|::|/|g;
  unless( $INC{$file} ) {
    require $file;
  }# end unless();
  $class->import(@_);
}# end load_class()
