This is the file Glue.pm?  I have no idea why it would be like that, it is
completely wrong.  It may be related to the problem mentioned below with
@INC.

The cpan-mac instructions tell you to put site_perl in your prefs, so it
comes before lib.  This could be the cause of problems.  Go into the prefs
and add it, if you haven't already.

There should be no difference in the methods.  What clear warning was there
to use the compressed file?

Such warnings are sometimes the result of a poorly constructed MANIFEST
file, which is the case here.  No worries, it worked fine.

It depends on the machine.  On my PowerBook G3/292, it is about one second.

Exactly.  Perl doesn't precompile.  With every Perl program, the program is
compiled each time it is run.  This is not the case with AppleScript and
Frontier, which can save a script in a compiled state.

Well, there is experimental support for that in perl 5.005, and that may
someday work with MacPerl, but for now, you are stuck with "recompiling"
every script you run, every time it is run.

  #!perl -w
  use Mac::Glue;
  $e = new Mac::Glue 'Eudora Pro';
  print $e->get( $e->prop(selected_text => window => 1) );

See the Mac::Glue docs for object specifier records.


>Is it possible to use the raw event codes rather than loading the library?

What library?  You mean, Mac::Glue?  Sure, you can use Mac::AppleEvents or
Mac::AppleEvents::Simple.  I show some benchmarks for speed differences in
the Mac::Glue docs.

Merry Christmas,
