Subject: casting question
Message-Id: <1099768917.343772@nntp.acecape.com>
hi all,
i have in my code
my $IMobj = Mail::Internet->new($$array_ref[$y]);
which gives me the object....from the watch in the debugger I have
{$IMobj->{mail_inet_body}}
which shows as type ARRAY.
so i wrote
foreach $email_line ({$IMobj->{mail_inet_body}})
assuming that that was the proper way, and of course the compiler reads it
as scalar and doesn't accept it ... so am unsure how to CAST it
properly...not even sure that CAST is the right word to use in Perl...
I guess thought if i could see it as an array in WATCH, that the same format
would apply to code itself, no?
thanks ahead,
daniel

Posting isolated bits and pieces of code completely devoid of context is
not a good way to ensure that you get answers. Don't do that. Post a
small, self-contained script that does not do what you want and give an
explanation of what you want.
It seems to me that you still have not read the posting guidelines, you
are still not using strict and warnings and hence you deserve whatever
you get yourself into.

seriously sinan, just stop answering my posts..you waste your time, my time,
and anyone else's who likes to read threads.
these are the only two line that matter, to post 2 pages of code is a waste,
especially since the code works, i have to go and change passwords and
URLs...
so where is the harm, this is the object i have
my $IMobj = Mail::Internet->new($$array_ref[$y]);
and would like to use the array
{$IMobj->{mail_inet_body}
within a foreach loop , yet every way i type it ....i.e. foreach
$email_line ({$IMobj->{mail_inet_body}})
the compiler sees it as a scalar...
besides, it is a CASTING question is what it is, nothing more...
seriosuly, what is your problem? some guy here just posted "how do i save to
a file" not only did some people just
answer him, but those that sent him to the perldoc, did so without
attitude....
i have a CASTING question, nothing more....have a problem with me, stop
please killfile me, stop reading my posts, and stop being such a miserable
wretch of a human being.

Just a guess as I haven't looked into it, but try removing the outer pair of
{}, they don't seem to be appropriate in the context.

It looks to me like you ain't using strict because I do not see a
declaration of $email_line before its first use.
> besides, it is a CASTING question is what it is, nothing more...
Oh yes it is. For example, why on God's green earth are you mucking about
with the internals of the Mail::Internet object?
Mail::Internet has a public interface. That is what you are supposed to
use. You get the message body using the Body method. That is a reference to
an array. You need to dereference that. You could not have been much of a C
programmer not knowing the difference between casting and dereferencing.

That was his first time. He hasn't come back yelling at people who have
given him good advice.
> i have a CASTING question, nothing more....have a problem with me,
> stop please killfile me, stop reading my posts
You do not have a casting question. You have a problem that has been caused
by the fact that you went mucking about the internals of the Mail::Internet
object you created. You are not following good practices. Your posts are
available to the whole wide world to see on Google. If your errors remain
uncorrected, someone, somewhere down the road might see them and think "A-
ha, maybe this is the way to go". All of us are trying to prevent that from
happening.

Please do not guess. The documentation for the module the OP is using
clearly states what public interface it provides. All access to instance
data must be mediated through that public interface.
An instance of Mail::Internet provides access to the lines of the body of
the message through the Body method. One can also access the whole message
using the as_string method.

thanks for the suggestion dave, and for making it without kicking me in the
teeth,
here are just a few of the ones that i have tried and they all give the same
error msg
Scalar found where operator expected
foreach $email_line ( $$IMobj->{mail_inet_body} )
foreach $email_line ( $IMobj->{mail_inet_body} )
foreach $email_line ( {$IMobj->{mail_inet_body}} )
foreach $email_line (@{$IMobj->{mail_inet_body}})
and since in the watch window of the debugger {$IMobj->{mail_inet_body}} is
seen as type ARRAY, i just assumed that that woudl apply to all Perl,
i would assume, that this is just a casting question....but as they always
say, never assume, cause when you assume, you make an a** out ot me and me

The docs for Mail::Internet say that options may be passed as key-value
pairs, like a hash. Why aren't you doing what the docs say to do?

The docs for Mail::Internet say that the body() method is how to
retrieve the body of the email. Why aren't you doing what the docs say
to do?

It's not, and no assuming is necessary to see that. Why aren't you doing
what the docs say to do?

No. Why are you guessing instead of reading the docs for the module
you're using?

it's declarted, otherwie the error would be a little more obvious...i do all

yeah, let's not go and judge each other on how little we know of each
other...you don't know what i have done, gotten paid, gotten recognized for,
as the same applies to me looking at you....
if i were to judge you by just your posts, which is all you have of me and

miserable human being, who needs go out and get a girl (or a guy if you
refer...i don't judge there either....actually your hostility towards me
might tend me to say it's the latter )....but i'll refrain from such
judgements till we get to know each other

obviosuly OBJECTS are new to me as well as Perl, which is why in my OP i
said i clarified that i might have a casting problem...
and anyone finding my posts via a google search who would copy from my posts
where i say "help me, this doesn't work"...well hey, that's an obvious
one...

Then post your real code. The code you posted does not compile when
strict is enabled.

Bullshit. Type casting is a C question. Perl is not C. Perl is weakly
typed, and no type casting is supported or needed.

Those who did so to your first question also did so without attitude.
After several more questions that showed your complete unwillingness to
read and/or search the docs - including this one - you're getting
exactly the responses your "please spoon-feed me" questions warrant.
You're reaping what you've sown here, nothing more or less.
> i have a CASTING question, nothing more
Then post your question to a language group where type casting is relevant.

Bad habit.

Not using the object's public interface that is documented in its
documents.

This thread seems like an advertisement for the benefits of C++ and
restricted access to private and protected class methods and members.
Can you use C++ class libraries in Perl?
I think that's what Microsoft's goal is with .net, to bring all languages
together with a common class library.
A future version of Perl will surely implement restricted access in classes
like C++. Those guys really thought out the OO thing carefully.
All languages, as they mature, become more C++-like.

and whether you believe me or not, thanks, cause the above is the
answer...rather than looking within the object i shoudl use the object, am
C, not C++ guy....would have saved us both alot of typing had you just said
that...
would still very much like to figure out the syntax tho for my first
headache... and shouldn't casting and derefencing be the same thing? aren't
they both NO-OP?

thank you for pointing out my actual error....as i just explained in another
post, am just C, not C++, so learning objects as well as Perl...from being a
C guy, i guess i just followed 'that' instinct, which was to just seeobjects
as just structures to use and go into, if that makes sense....obviously will
have to be more assertive and dtop looking at allt his from my old point of
view...
again, thank you for pointing out my actual error

always thank someone who "attempts" to help you, someone who took the time
to respond, whether they were right or wrong....it's someone who stopped for
one moment during their possibly possible to try try and lend a hand to a
stranger....always thank them for that, otherwise you become, well , like

Good programmers have the common sense and self discipline to respect
object boundaries without being forced to. Bad programmers blame the
language they're using when they make foolish decisions.

wow, that's good, you reached really far for that one....want to resort t
name calling? fine...can i invite you to do that again personally via my
email? or would you rather contniue to clutter up the threads here with
more useless name calling...
wow, i just realized....you (and others) scream about the noise level hear,
and how it drives good people away. yet, whenever i have inited anyone (and
definitly you) to take the insults, and personal stuff to email, you
don't....yet you contniue to write useless posts here...who's really at
fault for making the noise level then? remember, the least common
denominator in every f-ed up relationship you have ever had, is "you"
TA!

Try following your own advice. Many people here have attempted to help
you, and given you *much* better advice than the person you thanked -
and you yelled at them and called them names in return.

Now, in which way could objects and casting possibly be related?
The one has absolutely nothing to do with the other.
The only place in Perl where you might find something like "casting" is to
add a 0 to get the numerical value of a scalar or append an empty string to
get the text value. But even to call that casting would be a stretch.

It doesn't matter *why* you thought it was a type casting question. The
fact remains that type casting is not at all relevant to Perl.

For what it's worth, it's been my experience that the idea of "opaque
structures" (aka objects) is becoming more common in C too. Obviously in
C you'd write it as "do_something(obj,...)" instead of
"obj->do_something(...)", but that's just a trivial matter of syntax.
The high-level concept isn't really all that different.
The C toolkits I'm most familiar with - Gtk (Linux) and Core Foundation
(Mac) - make *heavy* use of the idea. Perhaps it's not as popular in the
Windows world you're coming from.

Read or not, as you wish, but you're not the boss of this group. You
can't end the thread.
