It does this via some slightly insane perlguts magic. import use Devel::BeginLift qw(list of subs); Calls Devel::BeginLift->setup_for(__PACKAGE__ => \@list_of_subs); unimport no Devel::BeginLift; Calls Devel::BeginLift->teardown_for(__PACKAGE__); setup_for Devel::BeginLift->setup_for($package => \@subnames); Installs begin lifting magic (unless already installed) and registers "${package}::$name" for each member of @subnames to be executed when parsed and replaced with its output rather than left for runtime. teardown_for Devel::BeginLift->teardown_for($package); Deregisters all subs currently registered for $package and uninstalls begin lifting magic is number of teardown_for calls matches number of setup_for calls. setup_for_cv $id = Devel::BeginLift->setup_for_cv(\&code); Same as "setup_for", but only registers begin lifting magic for one code reference. Returns an id to be used in "teardown_for_cv". teardown_for_cv Devel::BeginLift->teardown_for_cv($id); Deregisters begin lifting magic referred to by $id.

} sub bar { "bar: $_[0]\n"; } for (1 .. 3) { print foo($i++); print bar($i++); } no Devel::BeginLift; print foo($i++); outputs - foo: 0 bar: 1 foo: 0 bar: 2 foo: 0 bar: 3 foo: 4 =head1 DESCRIPTION Devel::BeginLift 'lifts' arbitrary sub calls to running at compile time - sort of a souped up version of "use constant". It does this via some slightly insane perlguts magic. =head2 import use Devel::BeginLift qw(list of subs); Calls Devel::BeginLift->setup_for(__PACKAGE__ => \@list_of_subs); =head2 unimport no Devel::BeginLift; Calls Devel::BeginLift->teardown_for(__PACKAGE__); =head2 setup_for Devel::BeginLift->setup_for($package => \@subnames); Installs begin lifting magic (unless already installed) and registers "${package}::$name" for each member of @subnames to be executed when parsed and replaced with its output rather than left for runtime. =head2 teardown_for Devel::BeginLift->teardown_for($package); Deregisters all subs currently registered for $package and uninstalls begin lifting magic is number of teardown_for calls matches number of setup_for calls. =head2 setup_for_cv $id = Devel::BeginLift->setup_for_cv(\&code); Same as C, but only registers begin lifting magic for one code reference. Returns an id to be used in C. =head2 teardown_for_cv Devel::BeginLift->teardown_for_cv($id); Deregisters begin lifting magic referred to by C<$id>. =head1 AUTHOR Matt S Trout - Company: http://www.shadowcatsystems.co.uk/ Blog: http://chainsawblues.vox.com/ =head1 LICENSE This library is free software under the same terms as perl itself =cut 1; libdevel-beginlift-perl-0.001003/t/000077500000000000000000000000001174463312500166755ustar00rootroot00000000000000libdevel-beginlift-perl-0.001003/t/constcalc.t000066400000000000000000000014361174463312500210370ustar00rootroot00000000000000BEGIN { our @warnings; $SIG{__WARN__} = sub { push(@warnings, $_[0]); } } use Devel::BeginLift 'foo'; use vars qw($int); BEGIN { $int = 1 } sub foo { warn "foo: $_[0]\n"; $int++; 4; } sub bar { warn "bar: $_[0]\n"; $int; } warn "yep\n"; warn foo("foo")."\n"; warn bar("bar")."\n"; no Devel::BeginLift; foo(''); END { use Test::More 'no_plan'; our @warnings; is(shift(@warnings), "foo: foo\n", "compile-time foo call first"); is(shift(@warnings), "yep\n", "manual warning"); is(shift(@warnings), "4\n", "const return from compile-time foo"); is(shift(@warnings), "bar: bar\n", "bar called at run-time"); is(shift(@warnings), "2\n", "\$int was incremented"); is(shift(@warnings), "foo: \n", "run-time foo after BeginLift disabled"); ok(!@warnings, "no more warnings"); } libdevel-beginlift-perl-0.001003/t/generate.t000066400000000000000000000014311174463312500206530ustar00rootroot00000000000000use strict; use warnings; use Test::More; BEGIN { plan skip_all => "B::Generate required" unless eval { require B::Generate }; plan skip_all => "B::Utils required" unless eval { require B::Utils }; plan tests => 2; } sub foo { B::SVOP->new("const", 0, 42); } sub gorch ($) { my $meth = ( $_[0]->kids )[-1]->sv->object_2svref; $$meth = "other"; $_[0]; } use Devel::BeginLift qw(foo gorch); sub bar { 7 + foo() } is( bar(), 49, "optree injected" ); sub blah { foo(31) } is(blah(), 42, "optree injected" );; sub meth { 3 } sub other { 42 } __END__ my $obj = bless {}; sub oink { gorch $obj->meth; } is( oink(), 42, "modify method call"); my @args = ( 1 .. 3 ); sub ploink { gorch $obj->meth(1, @args); } is( ploink(), 42, "modify method call with args"); libdevel-beginlift-perl-0.001003/t/liftvar.t000066400000000000000000000005131174463312500205300ustar00rootroot00000000000000use strict; use warnings; use Test::More 'no_plan'; sub foo { $_[0] = $_[1]; (); } sub bar { is($_[0], 'yay', 'Var set ok by sub'); (); } sub baz { () } sub quux { is($_[0], 'w00t', 'Var set ok by ='); (); } use Devel::BeginLift qw(foo bar baz quux); foo(my $meep, 'yay'); bar($meep); baz(my $lolz = 'w00t'); quux($lolz); libdevel-beginlift-perl-0.001003/t/proto.t000066400000000000000000000011031174463312500202200ustar00rootroot00000000000000BEGIN { our @warnings; $SIG{__WARN__} = sub { push(@warnings, $_[0]); } } use strict; use warnings; sub foo (&) { $_[0]->(); (); } sub bar { my ($name, $val) = @_; no strict 'refs'; *{$name} = sub (&) { $_[0]->($val); }; } use Devel::BeginLift 'foo'; foo { bar "boom1" => "BOOM 1"; bar "boom2" => "BOOM 2"; }; boom1 { warn "1: $_[0]\n"; }; boom2 { warn "2: $_[0]\n"; }; END { use Test::More 'no_plan'; our @warnings; is(shift(@warnings), "1: BOOM 1\n", 'boom1'); is(shift(@warnings), "2: BOOM 2\n", 'boom2'); ok(!@warnings, 'No more warnings'); }
