NAME

       Test2::Util::Sub - Tools for inspecting and manipulating subs.

DESCRIPTION

       Utilities used by Test2::Tools to inspect and manipulate subroutines.

EXPORTS

       All exports are optional, you must specify subs to import.

       $name = sub_name(\&sub)
           Get the name of the sub.

       my $hr = sub_info(\&code)
           This returns a hashref with information about the sub:

               {
                   ref        => \&code,
                   cobj       => $cobj,
                   name       => "Some::Mod::code",
                   file       => "Some/Mod.pm",
                   package    => "Some::Mod",

                   # Note: These have been adjusted based on guesswork.
                   start_line => 22,
                   end_line   => 42,
                   lines      => [22, 42],

                   # Not a bug, these lines are different!
                   all_lines  => [23, 25, ..., 39, 41],
               };

           $info->{ref} => \&code
               This is the original sub passed to "sub_info()".

           $info->{cobj} => $cobj
               This is the c-object representation of the coderef.

           $info->{name} => "Some::Mod::code"
               This is the name of the coderef. For anonymous coderefs this may end with
               '__ANON__'. Also note that the package 'main' is special, and 'main::' may be
               omitted.

           $info->{file} => "Some/Mod.pm"
               The file in which the sub was defined.

           $info->{package} => "Some::Mod"
               The package in which the sub was defined.

           $info->{start_line} => 22
           $info->{end_line} => 42
           $info->{lines} => [22, 42]
               These three fields are the adjusted start line, end line, and array with both.  It
               is important to note that these lines have been adjusted and may not be accurate.

               The lines are obtained by walking the ops. As such, the first line is the line of
               the first statement, and the last line is the line of the last statement.  This
               means that in multi-line subs the lines are usually off by 1.  The lines in these
               keys will be adjusted for you if it detects a multi-line sub.

           $info->{all_lines} => [23, 25, ..., 39, 41]
               This is an array with the lines of every statement in the sub. Unlike the other
               line fields, these have not been adjusted for you.
