Subject: [MacPerl] Need help on GetFileInfo...
Hi,
Yes, I'm a newbie. (Not much I can do about it, so I guess I won't
bother apologizing). Anyways, I am having trouble getting the following
to work correctly:
my ($target_link, @dir_list, $file_type, @movie_list);
@dir_list = readdir IMAGEDIRECTORY;
foreach $target_link (@dir_list) {
$file_type = MacPerl::GetFileInfo($target_link);
}
if ($file_type eq "MooV") {
push @movie_list, $file_type;
}
When I try to access $file_type in the 6th line of code, I get a "use
of uninitialized value" message. I tried printing $file_type and it
appears to be NULL ($target_link has the correct value when I print
it). I'm using the latest version of MacPerl (downloaded yesterday).
What am I missing here?
Thanks for your time!

Can someone send me a copy of sendmail.pl ? I am not using a
unix server, I am using a Mac with First Class running macperl.
(yes, finally got it working!).

Never heard of sendmail.pl. Try usin MailTools or Net::SMTP by itself.

Are you currently in the directory specified by IMAGEDIRECTORY? If not,
you need to either append that directory to the variable (e.g.,
"$dir:$target_link" or "$dir$target_link") or change directories to it
(e.g., chdir($dir) or die "Can't chdir to '$dir'").

This may not be all of it, but it certainly is part of it: your if
statement is _outside_ your foreach loop; this leads to a problem that
the $file_type variable is reassigned each time through the loop and
comes out with just the last value. Second, you're push the file type
on your movie list, not the file name which is in $target_link, which
is what I think you want to do (otherwise you end up with a list of
{"MooV", "MooV", ... }). I think you want something more like this:
foreach $target_link (@dir_list) {
$file_type = MacPerl::GetFileInfo($target_link);
if ($file_type eq "MooV") {
push @movie_list, $target_link;
}
}

What Chris said.
Short and very sweet example using Net::SMTP and Mac::InternetConfig (The
latter just to get the sender's email address). Can't recall if this is
on the MPPE CD-ROM. I don't *think* I wrote this, although a greatly
modified version now resides on my hard disk.
Mailtools makes some Unixy assumptions which Paul Schinder has taken care
of most of in the Mac port. If you use Mailtools be sure to read the
"README.Mailtools.mac" file (duh!).
#!perl
use strict;
use Net::SMTP;
use Mac::InternetConfig;
my($smtp, $email, @emails, $subject, $message);
$smtp = Net::SMTP->new();
$email = $InternetConfig{kICEmail()}; # get sender from IC
@emails = 'some_user@some.domain'; # recipient goes here
$subject = "Subject: MacPerl test message\n\n";
$message = <<EOM;
Place test message here
EOM
$smtp->mail($email) or warn('failure');
$smtp->to(@emails) or warn('failure');
$smtp->data() or warn('failure');
$smtp->datasend($subject) or warn('failure');
$smtp->datasend($message) or warn('failure');
$smtp->datasend() or warn('failure');
$smtp->quit() or warn('failure');

Subject: [MacPerl] What are MacPerl's capabilities
Hey guys,
I have looked at MacPerl and read the manual to a point. I am impressed
so far but I have a couple of questions:
1) How far can MacPerl go in allowing me to use the Mac Toolbox to do
things like display a window with the ability to enter into fields any
information I want and store it in a database of my own design?
2) If so, does MacPerl hide the Mac Toolbox enough that I don't have to
be a C/C++ programmer to use it?
3) What resource is their for understanding the OO portion of MacPerl.
I don't want to buy books and programming tools for MacPerl unless it
will meet my needs. Currently I work with 4th Dimension and Oracle. I
would like to have an alternative to 4D for developing front ends.
Thanks in advance!!!
Robert Pollard

Just to be pendantic, there's no longer a Mac port of Mailtools.
Mailtools now includes MacPerl support in the standard distribution,
and you can just grab and install the latest version from any CPAN
site.
There are also no longer Mac ports of libnet, libwww-perl-5, and URI,
and I will be sending off patches for Font::AFM and File::CounterFile
shortly. Let's hope that in the near future the only need for "Mac
ports" will be for XS modules.

Yes. :)

Yes, though the functions are mapped closely to their C equivalents, so
being a C programmer of the Mac helps.
The best resources for using the functions themselves is still Inside
Macintosh, available for free as PDF and HTML files at
<URL:http://www.appler.com/developer/>. For the MacPerl usage, see this
list, the MacPerl book, and the macperl-toolbox list.
>3) What resource is their for understanding the OO portion of MacPerl.
The best resources for OO in MacPerl are not specific to MacPerl. Several
books are good, including Perl: The Programmer's Companion, Effective Perl
Programming. There is the MacPerl book, which does not discuss OO more
than a page or two. There are some good manpages, that come with perl and
are here:
<URL:http://www.perl.com/CPAN-local/doc/manual/html/pod/perlref.html>
<URL:http://www.perl.com/CPAN-local/doc/manual/html/pod/perldsc.html>
<URL:http://www.perl.com/CPAN-local/doc/manual/html/pod/perllol.html>
<URL:http://www.perl.com/CPAN-local/doc/manual/html/pod/perltoot.html>
<URL:http://www.perl.com/CPAN-local/doc/manual/html/pod/perlobj.html>
You can skip dsc and lol if you like, but if you want to understand
references well, you might want to read them. Then there is the article
from MJD that is a new manpage as of 5.005_03, for more on references:
<URL:http://www.plover.com/~mjd/perl/FAQs/references.html>
>I don't want to buy books and programming tools for MacPerl unless it

There really isn't much of a need to buy tools. Most tools are free and
open, as are most docs. Some excellent books cost money, but you can get
good books for not much. I recommend, in addition to the books mentioned
above, the Perl Cookbook as a compendium for every perl programmer. The
others you should get as needed.
Good luck,

Well Chris, as I recall you or Matthias provided the Internet Config
patch to Graham for Mailtools, you and Arved are doing all the XS
builds, and you did the CPAN port. So thank you, too!

Sorry, but I couldn't resist rewriting it using Mail::Sendmail. It's
shorter and will also give you clear error messages if needed, do Mime
quoted-printable encoding for you, etc...
#!perl
use strict;
use Mail::Sendmail;
use Mac::InternetConfig;
my %mail = (
From => $InternetConfig{kICEmail()}, # get sender from IC
To => 'some_user@some.domain', # recipients go here
Subject => "MacPerl test message",
);
$mail{Message} = <<EOM;
Place test message here
EOM
sendmail(%mail) or warn $Mail::Sendmail::error;

I am not the C or Perl programmer that some of the folks on this list are,
but I do have lots of work writing database front ends in general and using
4D in particular. My experience has lead me to the following conclusions:
MacToolbox from MacPerl is easier than MacToolbox from C, but that is not
to say that it is easy. It is much (Much MUCH!) harder to use the MacPerl
MacToolbox to create a database front end than it is to use 4D.
IMHO, (Mac)Perl's strength is text processing. MacPerl's toolbox
routines, while greatly appreciated, do not yet make it my front end tool
of choice. Similarly, Perl is not my favorite object environment; when I
want objects, I use Python. YMMV.
Mac's weakness in memory and process management impact MacPerl relative
to Unix Perl; you can easily run out of memory in MacPerl, and the only
solution is to quit MacPerl and manually (and semipermanently) allocate
more memory to it. You can only run one MacPerl program at a time.
(Similar limitations apply to MacPython; I use MacPerl alot, Unix Python
alot, but rarely use MacPython.)
My experience with all software tools is that books are about the best
investment I can make. The cost of a book for a tool I don't use is
dwarfed by the cost of even a small investment of my time. MacPerl, Power
and Ease is a wonderful introduction, especially if you haven't worked with
Perl a lot (and even if you have; it puts all the Mac-specific stuff
together very nicely).

Sorry but I have to disagree with Chris on this one. Methinks that
MacPerl is a poor choice to build user-interfaces in. That stage is
still, huh, "under construction".
Now, talk about grabbing data from web forms or report logs, and putting
the data into a data base, or the reverse, getting data from a database
and generate HTML files on the fly (for example), now *that* is really
something that MacPerl (huh, "Perl" in general) really excels in. If you
ever need to do data manipulation, there's no time wasted in learning
Perl anyway.
>2) If so, does MacPerl hide the Mac Toolbox enough that I don't have to

It's still not obvious. It's a bit easier than in C/C++, but not much.
>3) What resource is their for understanding the OO portion of MacPerl.
Ah. Maybe Tom Christiansen's stuff, like PERLTOOT (included with Perl?),
or his articles available on www.perl.com (Is there a "Far more than you
ever wanted to know... about objects"?). Learning by example, i.e.
checking out how standard Perl modules use OO, could help a lot. Also,
check out reference.perl.com (there is a link and a search engine on the
homepage of www.perl.com) which may contain links to online tutorials.

Hmm... "front ends" is one thing I don't use Perl for. I'm not saying it
can't be done, but it definitely isn't amongst MacPerl's stronger
points. Yet. :-)
Wel, just one guy's opinion.
