Well, I've gotten several mails indicating interest in my perl
module. I've got a rough (*very rough*) patch ready and on the web:
http://www.phydeaux.org/perl/zperl-0.01.patch.gz
Something along the lines of the following should (in theory)
get you a zperl.so that can be zmodload'd when run against a copy of
the zsh-3.1.6 source tree:
cd ..../zsh-3.1.6
gunzip < zperl-0.01.patch.gz | patch -p1
./configure ... # may not be needed if already configured
cd Src
make modules # this will fail, see below
cd Modules/zperl
sh ./makezperl # this is a kludge
cd Zsh # Then install the perl side of things
perl Makefile.PL && make install
As I said, it's rough at the moment. Any sugguestions how to
get perl's cflags and ldflags into the mdd file in the correct way
would be welcome (they're generated with something like:
`perl -MExtUtils::Embed -e ccopts`
and the objects="" setting didn't like having -lfoolib in it).
There's not really any documentation to speak of, but the
commands are (once you've done `zmodload zperl.so'):
List any perl defined builtins commands
zperl -l
Have the perl interpreter require a perl module
zperl -r Perl::Module
Define a zsh builtin as a perl subroutine
zperl -b foo Perl::Sub
Undefine a builtin defined by zperl -b
zperl -u foo
I've been using a perl module along the following lines for
testing. Put this in a file named Ztest.pm somewhere that perl can
find it and do `zperl -r Ztest ; zperl -b perl_eval Ztest::eval'. You
can then evaluate arbitrary perl code with the new `perl_eval'
command.

package Ztest;
use Zsh;
sub eval {
my $code = shift;
eval " $code ";
if( $@ ) {
warn "Error during eval: $@\n";
return 1;
} else {
return 0;
}
}
1;
__END__
