Re: [Omaha.pm] here doc help

So I have a interesting issue that I need some assistance with.

I found a here doc "formatting" function on-line (at CPAN) that claims to
"expect input from a here doc".
I've made one little change to preserve "blank lines" (i.e, changed a couple
"\s" to "[\t ]"), hence the
function name.

Now I want to offload it into a require file.  however "perl -c" fails when
doing so.


It worked for me when I changed file3.pl to:

$cde_script = dequote_blank_lines(<<_EOF_
           #!/bin/sh

           #real code removed for brevity
           /usr/bin/echo "Hello World"

_EOF_
    );

    print $cde_script;

Note the parens, lack of ; after the heredoc initiator.

In general, it's considered best practice to always use parens with
non-core functions, so this is the Right Thing to do anyway.  I think
the parser was probably just getting confused with some ambiguity
there, although I'm not Perl wonk enough to know what the ambiguity
might have been.
