But in the case of a bareword, it assumes you mean a module. - -This gives nasty overhead when you are trying to dynamically require -modules at runtime, since you will need to change the module notation -(C<Acme::Comment>) to a file notation fitting the particular platform -you are on. - -C<load> eliminates the need for this overhead and will just DWYM. - -=head1 Rules - -C<load> has the following rules to decide what it thinks you want: - -=over 4 - -=item * - -If the argument has any characters in it other than those matching -C<\w>, C<:> or C<'>, it must be a file - -=item * - -If the argument matches only C<[\w:']>, it must be a module - -=item * - -If the argument matches only C<\w>, it could either be a module or a -file. We will try to find C<file> first in C<@INC> and if that fails, -we will try to find C<file.pm> in @INC. -If both fail, we die with the respective error messages. - -=back - -=head1 Caveats - -Because of a bug in perl (#19213), at least in version 5.6.1, we have -to hardcode the path separator for a require on Win32 to be C</>, like -on Unix rather than the Win32 C<\>. Otherwise perl will not read its -own %INC accurately double load files if they are required again, or -in the worst case, core dump. - -C<Module::Load> cannot do implicit imports, only explicit imports. -(in other words, you always have to specify explicitly what you wish -to import from a module, even if the functions are in that modules' -C<@EXPORT>) - -=head1 ACKNOWLEDGEMENTS - -Thanks to Jonas B. Nielsen for making explicit imports work. - -=head1 BUG REPORTS - -Please report bugs or other issues to E<lt>bug-module-load@rt.cpan.org<gt>. - -=head1 AUTHOR - -This module by Jos Boumans E<lt>kane@cpan.orgE<gt>. - -=head1 COPYRIGHT - -This library is free software; you may redistribute and/or modify it -under the same terms as Perl itself. - - -=cut |
