I've confirmed that it was part of the OLD sdk, and not available where it
used to be.
It used to be available as part of
<ftp://ftp.apple.com/devworld/Development_Kits/AppleScript/AppleScript_Set
up/Apple%27s_Scripting_Syste.sit.hqx>
However, 7Edit, availabe in
ftp://ftp.apple.com//devworld/Tool_Chest/OS_Utilities/Apple_Events/AE_Sample_App
lications.sit.hqx
might serve just as well. In particular, it supports some of the same odd
AppleEvent terminology that our favorite perl editor does (like "Spot").

The only location I know of is Danny Goodman's FTP site. It is
contained in his 1MB tutorial file package called AppleScript
Handbook. Kind of heavy considering that Scriptable Text Editor is
only about 100k, uncompressed.

Subject: Re: [MacPerl] EBCDIC in, ASCII out?
Just an FYI. My message was forwarded to somebody familiar with IBM
systems, and this person kindly pointed out to me that I was doing things
the hard way.
All I needed to do was FTP the file as a text file, and the FTP daemons
handle the EBCDIC->ASCII conversion. This person was working with 390s,
but the behavior is the same on the AS/400 I'm working with.
Thought some might like to know. Thankfully, perl makes the conversion
easy, so I didn't lose a lot of time solving this problem.
Thanks all,

You want to present a dialog box to get or put files? Use the
Mac::StandardFile package. It's the best way to go.

Whenever dealing with times using MacPerl, it's always a good idea to
remember that current Mac times are already > 2^31 seconds past Jan 1,
1904. So you have to keep Perl from interpreting this as a signed
integer, or you're hosed. One useful trick is to assign or pass
$time | 0. This won't change the value at all, but seems to force Perl
to interpret the value as an unsigned integer, which is what you want.
Without seeing any code, I can't tell you any more than this.

Subject: [MacPerl] Mac::Navigation glue
On the recent topic of Nav Services, I have written a "glue" for the
Mac::Navigation" module. Name the module "NavServices.pl" and put it in your
site_perl folder. To test it, use the following script:
#!perl -w
use strict;
print &GetFiles("Select some files to open.", undef, qw[TEXT ttro]);
Here is the complete definition for the GetFiles subroutine:
&GetFiles(prompt, defaultFolder, typeList, dialogOptions);
The sub will automatically use StandardFile.pl if Nav Services are not
available.
More coming soon, stay tuned!
#!perl -w
# &GetFiles(prompt, defaultFolder, typeList, dialogOptions);
sub GetFiles {
use Mac::Navigation;
use Mac::Files;
use strict;
my($text, $default, @types, $options, $nav, $file, $numFiles, $i, @files) =
@_;
if (NavServicesAvailable && NavServicesCanRun) {
if (!defined ($options)) {$options = NavGetDefaultDialogOptions()};
$options->message($text);
$options->windowTitle($text);
$options->dialogOptionFlags(
$options->dialogOptionFlags | kNavNoTypePopup); # Get rid of type popup
my $types = new NavTypeListHandle "McPL", [@types];
local($^W) = undef;
$nav = NavGetFile($default, $options, $types, sub {use
Mac::Events;Mac::Events::DispatchEvent($_[1]->event);});
if ($nav && $nav->file(1)) {
if (wantarray()) {
$numFiles = $nav->count;
for $i (1 .. $numFiles) {
push(@files, $nav->file($i));
}
return @files;
} else {
$file = $nav->file(1);
return $file;
}
}
} else {
require "StandardFile.pl";
return $_ if defined($_ = StandardFile::GetFile($text, @types));
}
}

Subject: Re: [MacPerl] Mac::Navigation glue
Cool, this is what I've wanted to see for some time. Maybe a module called
Mac::GetFile or something. Mac::FileDialogs. I dunno. Should work with
StandardFile.pm and Navigation.pm. Some suggestions:
* Uses Mac::StandardFile, not StandardFile.pl.
* Most people don't have Mac::Navigation. Better to do something like:
my $hasnavservices = do 'Mac/Navigation.pm';
Then when it comes time later:
if ($hasnavservices) {
Mac::Navigation->import;
# ...
} else {
require Mac::Standard File;
Mac::StandardFile->import;
# ...
}
Also, it would be nice to extend this to do putting of files to, and maybe
choosing of objects or something, too.

Thanks for the module, it has clarified some things that I have been
struggling with (such is life when trying to learn Mac toolbox programming,
C/C++ and MacPerl simultaneously). Namely, I was trying simply to get the
NavGetFile dialog to be movable, and resizable. The simplest way I found wa
to give it a dummy eventProc subroutine, but the dialog would not always
update itself properly. The subroutine:
sub {use Mac::Events;Mac::Events::DispatchEvent($_[1]->event);}
seems to have cured most of the anamolies I was observing, but not all.
A few questions:
1) Why must the use Mac::Events statement appear within the embedded
subroutine in order to work properly? I tried placing it at the beginning
of my script with my other use statements, and got an error saying
DispatchEvent subroutine was undefined. Is this, in general, necessary when
calling 'external' module functions/structures in embedded subroutines?
2) What "entity" does DispatchEvent contact to notify the dialog to handle
the current event (I assume it is the NavGetFile's handlers that need to be
executed), the system? the dialog directly?
3) Has anyone who has tried NavServices.pl observed that the cursor becomes
"jumpy", or turns into a MacPerl Camel with a spinning wheel?
4) I have also been using NavPutFile, which displays a movable, resizable
dialog by default. It does not suffer from the cursor anamolies that I
observe with NavGetFile, and additionaly the shareware Default Folder 3.0.1
modifies the navigation buttons in the dialog as I would expect, which is
nice. This does not happen with NavGetFile, and coupled with the cursor
problem leads me to wonder whether a) something else needs to be added to
the eventProc subroutine, or b) maybe there is a bug in Navigation.pm. Any
thoughts?

Trying to use Net::FTP with MacPerl. At this point my program simply looks

When run, I get the error messages list below. I'm using the release right

Because the human lifespan is incommensurate with the task of maintaining
MacPerl. Because I'm rarely around printers. Because I prefer pod2ps for
printing pod. Because I wanted to make Shuck as small as possible.

I believe there are two bugs in Navigation.pm which are relevant:
1 Only the first element in the list of types is recognised. The error
is in Navigation.pm which inserts spurious white spaces into the list
handle ('NavTypeListHandle').
2 *Any* EVENTPROC in 'NavGetFile()' results in a serious memory leak at about
240K per minute continuously while the dialog is onscreen. Leaked memory is
not reclaimed when the window is closed, so that "Out of memory" crashes
can occur quite frequently.
The first bug is easily fixable (see sister-list [macperl-modules], 31
March, "Using Mac::'...'Modules"), the second is more difficult. Since
EVENTPROC has to be called before either PREVIEWPROC or FILTERPROC, neither
of these is usable without incurring the memory leak from EVENTPROC.

I think the cursor behaviour is associated with bug 2 -- MacPerl is busy
eating pointer space.
I would like to tinker with Navigation.xs to see if (however unlikely) I
can do anything to improve it. However my attempts to build the evisting
Navigation.xs have all failed at the 'compile' stage. I'm pretty sure I
have not got the 'typemap' right. If the 'typemap' for Navigation.xs could
be made available it would be a great help.
