Module Version: 0.002000   Source   Latest Release: Devel-GlobalPhase-0.002002

NAME ^

Devel::GlobalPhase - Detect perl's global phase on older perls.

SYNOPSIS ^

    use Devel::GlobalPhase;
    print global_phase; # RUN

    use Devel::GlobalPhase -var;
    print ${^GLOBAL_PHASE}; # RUN

DESCRIPTION ^

This gives access to ${^GLOBAL_PHASE} in versions of perl that don't provide it. The built in variable will be used if it is available.

If all that is needed is detecting global destruction, Devel::GlobalDestruction should be used instead of this module.

EXPORTS ^

global_phase

Returns the global phase either from ${^GLOBAL_PHASE} or by calculating it.

OPTIONS ^

-var

If this option is specified on import, the global variable ${^GLOBAL_PHASE} will be created if it doesn't exist, emulating the built in variable from newer perls.

BUGS ^

There are tricks that can be played with B or XS that would fool this module for the INIT and END phase.

AUTHOR ^
