Requiring strictness everywhere

Yes, I know I am generating most of this month's threads,
but
migrating to a new way of working always raises questions
 I
looked
this up as well, but could only find a 2002 conversation [1]
that left
me exactly where I was at the beginning.

I am a fan of writing Perl under the influence of the
'strict'
pragma. It is a great butt-saver. In fact, yesterday I
committed a
bunch of changes [2] introducing a [$ var $dummy $] line to
each of my
pages. 

Anyway... If this is just to be filed as a wishlist request,
so be it
- But we humans tend to forget stuff. I'm sure I will
create one or
three webpages, and then forget to set the [$ var $dummy $]
line on
them. No great deal, but it breaks what I expect from the
compiler. It
would be great if I could just tell Embperl to enforce
strictness on
all of its files, at least on all which are not with
Syntax=>'Perl'.

If there is a way, please point me to it

You can use Embperl_Top_Include in your httpd.conf to add a
"use strict" to
every page

Hmh... Does not appear to work - Having that variable set in
my
configuration, the pages still display even if having
undeclared
variables. Besides, trying to specify it from within
base.pm, I did:

    $epreq->config->top_include = 'use strict;';

and got:

[Fri Aug 11 16:22:25 2006] [error] [9242]ERR:  24:  Error in
Perl code: Can't locate object method
"top_include" via package
"Embperl::Req::Config" at
/home/gwolf/cvs/comas/trunk/embperl/base.pm line 49.

This is using Embperl 2.0rc3-1 (the version shipped in
Debian
Sarge). The code does get executed, but I guess this happens
inside an
eval block, so it does have any real effect - I tried also
setting
EMBPERL_TOP_INCLUDE to "warn 'Alive';", and
-as expected- got:

This means, once for each file evaluated.

Ok, you are right it works for other "use"es,
but not for use strict,
because of scoping issues.

The only other chance is to modify Embperl/Syntax.pm, search
for "# any
initialisation could be put here" and add your use
strict.

Yes, of course this must be done before Embperl starts to
compile the page
and inside the base template this is already done.
