=head1 NAME
Test::Valgrind::Command::Perl - A Test::Valgrind command that invokes perl.
=head1 VERSION
Version 1.19
=cut
our $VERSION = '1.19';
=head1 DESCRIPTION
This command is the base for all C<perl>-based commands.
It handles the suppression generation and sets the main command-line flags.
=cut
use List::Util ();
use Env::Sanctify ();
use Test::Valgrind::Suppressions;
use base qw<Test::Valgrind::Command Test::Valgrind::Carp>;
=head1 METHODS
This class inherits L<Test::Valgrind::Command>.
=head2 C<new>
my $tvcp = Test::Valgrind::Command::Perl->new(
perl => $^X,
inc => \@INC,
taint_mode => $taint_mode,
%extra_args,
);
The package constructor, which takes several options :
=over 4
=item *
The C<perl> option specifies which C<perl> executable will run the argument list given in C<args>.
Defaults to C<$^X>.
=item *
C<inc> is a reference to an array of paths that will be passed as C<-I> to the invoked command.
Defaults to C<@INC>.
=item *
C<$taint_mode> is a boolean that specifies if the script should be run under taint mode.
Defaults to false.
=back
Other arguments are passed straight to C<< Test::Valgrind::Command->new >>.
