The world of Fortran has fsplit, which splits Fortran source into individual subroutines or functions (they're different in Fortran, which is neither here nor there).

My question is, then, is there a similar program available for Perl? I am not terribly concerned with anonymous subs, nor am I terribly concerned with cases like

{
  my %private_hash;

  sub build_data {
  # do magical stuff on %private_hash
  }
  sub get_item {
     my $item = shift;
     if(exists($private_hash{$item})){
         return $private_hash{$item};
      }
      else{
         return undef;
      }
   }
}

Thanks in advance!

<update: 13 Sept 2006>

Having the fairly typical combination of hubris and laziness of a Perl code walloper, I've decided to build my own solution.

Right now, my idea is to

• Ignore anonymous subs.
• Maintain a hash so that subs with names that differ only in case can be distinguished on file systems that fold case, forbid /upper|lower/ case, or ignore (but preserve) case in file names.
• Ignore (for now) any kind of blocking of subs, e.g., this:
  

  {
        sub one {
        # magical stuff here
        }
  
        sub two {
        # more magical stuff here
        }
  }

  will lose the enclosing braces.
• Everything after "__DATA__" or "__END__" tags will be put into a file (or files) named something like "<name of file being split>.<DATA or END, as appropriate>".
