NAME¶
autodie::ScopeUtil - Utilities for managing %^H scopes
SYNOPSIS¶
use autodie::ScopeUtil qw(on_end_of_compile_scope);
on_end_of_compile_scope(sub { print "Hallo world\n"; });
DESCRIPTION¶
Utilities for abstracting away the underlying magic of (ab)using "%^H"
to call subs at the end of a (compile-time) scopes.
Due to how "%^H" works, these utilities are only useful during the
compilation phase of a perl module and relies on the internals of how perl
handles references in "%^H". This module is not a part of autodie's
public API.
Methods¶
on_end_of_compile_scope
on_end_of_compile_scope(sub { print "Hallo world\n"; });
Will invoke a sub at the end of a (compile-time) scope. The sub is called once
with no arguments. Can be called multiple times (even in the same
"compile-time" scope) to install multiple subs. Subs are called in a
"first-in-last-out"-order (FILO or "stack"-order).
