So, I have a file which contains a number of PL/SQL procedure and function definitions which look like this:

procedure x (x in varchar2,
             y in number) is
BEGIN
 ...
END;

function m (z in number) is
BEGIN 
 ...
END;
[download]

And what I would like to do is create a "package header" file. That is a file which contains the function declaration, including its arguments. Like so:

procedure x (x in varchar2,
             y in number);


function m (z in number);
[download]

If someone could remedy my pathetic, pathologically uninformed desparate hack below, I would appreciate it.

#!/arudev/bin/perl

use strict;

my $file = shift or die "must supply body file";

open F, $file;

my $text  = join '', <F>;
my $regex = '(procedure|function).*?\(.*?\)';

while ($text =~ /$regex/gs) {
  print "*$1*",$/;
}
[download]
