Mason
I'm looking for a decent book to help get me up to speed with Mason but could only find Embedding Perl in HTML with Mason on Amazon - a paper edition from 2002 and a more recent 2010 edition on Kindle only. I'm a bit old fashioned and prefer to have a paper copy that I can scrawl all over - so does anyone know if/when the new edition is expected in paperback and is it worth buying? (BTW I'm just assuming the 2002 edition is *way* out of date - but correct me if I'm wrong!) Chris

Yes. Most of the time you'll either have an 'else' or want to add it

That's the main problem with unless - once you've written your

PerlMagick
I've tried installing PerlMagick on a MacBook (v10.6.4), but the make dies. I've posted a message on the ImageMagick forum, but alas no response. A lot of Googling only turns up the usual problems of not having installed ImageMagick properly in the first place, but that doesn't seem to be the problem here (at least as far as I can tell). Has anyone on London.pm had success installing PerlMagick on a Mac? Cheers, Chris.

Not helpful.
I was trying to be helpful by not going into too much detail saving time if
no one else has bothered trying to install it on a Mac!
What error are you getting?
.after lots of compiler warnings

I know nothing of makefiles, so can't even begin to work out what the missing
directory should be, or why its missing. I modified the following lines of
Makefile.PL to point to various libraries as suggested in the ReadMe, but
presumably messed up somewhere;
my $INC_magick = '-I../ -I.. -I/usr/X11/include/cairo
-I/usr/X11/include/pixman-1 -I/usr/X11/include/freetype2

Well - going out on a limb here - perhaps you installed it differently from
how I did? :)
$ cat config.sh

echo Perl lib: $plib

--prefix=/alt/local \
--with-perl
(I keep a non-system Perl installed below /alt/local)
Of course I did it differently! Which explains a lot. I'm now piecing together
what I DID do...
I clearly built ImageMagick --without-perl, because (as I've just found from
a few posts on the interweb) it simply doesn't compile with the system level
Perl, and I don't have a non-system Perl installed.
It was a week ago, and I didn't keep notes.

It is highly un-recommended to have have a module file which contains
a differently named package. That is to say your $LIB/My/Module.pm
should contain the package My::Module.
Forgive me for my ignorance I learnt all my ooPerl from Learning
Perl Objects, References and Modules, followed by browsing through
Object Oriented Perl by Damian Conway, and have no idea which (if
either) is considered a good introduction. But assuming Randal and Tom
know something about ooPerl, they have no problem with a module $LIB/
My/Module.pm like this;
package My::Module;
{ package my_mod;
sub new {
# etc
}
}
{ package my_other_mod;
our @ISA = qw( my_mod );
sub foo {
# more etc
}
}
1;
Which is the kind of structure I was referring to in the test script
example.
