Subject: A new PerlScript command that specializes the Perl command to scripts
X-Git-Tag: v1.01~7
X-Git-Url: http://git.vpit.fr/?a=commitdiff_plain;h=3968e3b9715c8e5e7eaf998012d434b914b9e126;p=perl%2Fmodules%2FTest-Valgrind.git

A new PerlScript command that specializes the Perl command to scripts

So that we can move the taint mode handling from Test::Valgrind to there.

+=head1 NAME
+
+Test::Valgrind::Command::PerlScript - A Test::Valgrind command that invokes a perl script.
+
+=head1 VERSION
+
+Version 1.00
+
+=cut
+
+our $VERSION = '1.00';
+
+=head1 DESCRIPTION
+
+This command is meant to abstract the argument list handling of a C<perl> script.
+
+=cut
+
+use base qw/Test::Valgrind::Command::Perl Test::Valgrind::Carp/;
+
+=head1 METHODS
+
+This class inherits L<Test::Valgrind::Command::Perl>.
+
+=head2 C<< new file => $file, [ taint_mode => $taint_mode ], ... >>
+
+Your usual constructor.
+
+C<$file> is the path to the C<perl> script you want to run.
+
+C<$taint_mode> is a boolean that specifies if the script should be run under taint mode.
+If C<undef> is passed (which is the default), the constructor will try to infer it from the shebang line of the script.
+
+Other arguments are passed straight to C<< Test::Valgrind::Command::Perl->new >>.
