Rather than munging the \f(CW%INC\fR by hand to mark these external modules as loaded, so they are not attempted to be loaded by perl, this module offers you a very simple way to mark modules as loaded and/or unloaded. .SH FUNCTIONS .IX Header "FUNCTIONS" .ie n .SS "$bool = mark_as_loaded( PACKAGE );" .el .SS "\f(CW$bool\fP = mark_as_loaded( PACKAGE );" .IX Subsection "$bool = mark_as_loaded( PACKAGE );" Marks the package as loaded to perl. \f(CW\*(C`PACKAGE\*(C'\fR can be a bareword or string. .PP If the module is already loaded, \f(CW\*(C`mark_as_loaded\*(C'\fR will carp about this and tell you from where the \f(CW\*(C`PACKAGE\*(C'\fR has been loaded already. .ie n .SS "$bool = mark_as_unloaded( PACKAGE );" .el .SS "\f(CW$bool\fP = mark_as_unloaded( PACKAGE );" .IX Subsection "$bool = mark_as_unloaded( PACKAGE );" Marks the package as unloaded to perl, which is the exact opposite of \f(CW\*(C`mark_as_loaded\*(C'\fR. \f(CW\*(C`PACKAGE\*(C'\fR can be a bareword or string. .PP If the module is already unloaded, \f(CW\*(C`mark_as_unloaded\*(C'\fR will carp about this and tell you the \f(CW\*(C`PACKAGE\*(C'\fR has been unloaded already. .ie n .SS "$loc = is_loaded( PACKAGE );" .el .SS "\f(CW$loc\fP = is_loaded( PACKAGE );" .IX Subsection "$loc = is_loaded( PACKAGE );" \&\f(CW\*(C`is_loaded\*(C'\fR tells you if \f(CW\*(C`PACKAGE\*(C'\fR has been marked as loaded yet. \&\f(CW\*(C`PACKAGE\*(C'\fR can be a bareword or string. .PP It returns falls if \f(CW\*(C`PACKAGE\*(C'\fR has not been loaded yet and the location from where it is said to be loaded on success. .SH "BUG REPORTS" .IX Header "BUG REPORTS" Please report bugs or other issues to <bug\-module\-loaded@rt.cpan.org<gt>. .SH AUTHOR .IX Header "AUTHOR" This module by Jos Boumans <kane@cpan.org>. .SH COPYRIGHT .IX Header "COPYRIGHT" This library is free software; you may redistribute and/or modify it under the same terms as Perl itself.
