Or seen "Apocalypse Now" which was based upon Conrad's book.
I basically feel a little like the Marlon Brando character to
zigsters Martin Sheen. Not to say that I'm mad or that Perl and
Perlmonks are akin to savages, far from it. But like the
savages proving more effective than the U.S Special forces,
Perl proves it's worth over programming languages on a daily
basis.
This is one of the first lessons I picked up in a Perl coder
rich environment: Perl is not wholly a scripting language and
not entirely a programming language. As a result it doesn't
sit entirely in the idiom of either. You will concede that
the coding philosophies for these two differ?
I am upset by the slanderous comment about side effects,
if I removed the return from the line of code you've
quoted and relied on the fact that Perl returns the value of
last item used in the sub-routine, then that would be a sort
of side-effect (I prefer to call them features). If you
really mean short-circuits, yes I've used them by the
bucket-load, what of it? Of course
if you dislike Perl's making things easy for you approach, there
are other languages that are also interpretted where you can
spend weeks doing the stuff that Perl does in a day.
I hold my hands up to the comments about all this code going
on one line, so:
return join('', (
$v[0]->[$h],
$h[!!$h],
$and[!!($h&&($t||$u))]
$v[!(1==$t&&($u+=10)&&($t=0))]->[$t],
$format{'space'},
$v[0]->[$u]
);
As to the lousy coding standards in this code. I can only
assume that people have avoided it since ar0n pointed
out that: lhoward has done this already. When I've finished
this I'll be hitting CPAN to study his method. I suspect
some people have refused to comment, from contempt of the
bad style. I concur that it is not nice but it is far from
illegible, some of it is made of Perl 'phrases' or 'clichés'
that I picked up, and after a while you look at and go ah that's a ....
This isn't obfuscation, it's unkempt and written in a style
too terse to be easily maintained 1. but in a
language where the optimisation is a false economy 2.
1.) I am however hoping that the numeric sequence we use won't change
in my life time ;o).
2.) I've done some tests with this, but too few to draw a
positive conclusion, I suspect there are more legible ways,
with less overheads. I'll see what lhoward did.
