Hi,
You don’t need Embperl::Object. Embperl::Object is only if you need to search
(sub-)directories, like objects.
You should do something the following
Gerald
use Embperl;
my $obj = Embperl::Execute({ object => 'test.epl' });
$obj -> head ;
- test.epl -
[$ sub head $]
Text in head
[$ endsub $]

OK, so I’ve decided to try to use import instead. I’m seeing this error:
--- embperl2.pl ---
use Embperl;
Embperl::Execute({ inputfile => 'test.epl', 'import' => 1 });
head();
--- test.epl ---
[$ sub head $]
head
[$ endsub $]
main
---
%perl embperl2.pl
[14900]ERR: 72: A Embperl sub is called and no Embperl request is running
$Embperl::req undefined DOM.xs 284 at /home/carsids/jthomp/perl/test/test.epl
line 11.
I thought maybe it’d help if I was running this inside of an Apache request
(I’m using CGI), but I get the same error.

Can you use import => 1 to get all the subs into the current namespace and just
check there?
Embperl::Object adds some overhead so I was just trying to avoid that. If thats
not an issue then just go ahead and set up the %ENV entries according to the
Embperl::Object doco and you're good to proceed with your $obj->can checks like
you intended.

You are correct, I wasn't thinking when I set up that epl file. As far
as the Execute({ sub => '...' }) option, I have been using that, however
I wanted to avoid the overhead of grep'ing the file first to see if the
function even exists. I want to call it if it exists, and not if it
doesn't. I figured the fastest way was to have Embperl process it using
object, and then do "if($obj->can('head')) { $obj->head(); }". Is there
a better way? (Also realize, that Embperl will be processing the whole
template in a second, so I figured since it does caching, I'd have very
little performance penalty.)

Hi John,
> I am attempting to use the Execute({ object => '...' })
> feature but am seeing strange results. Here are my two files:
Firstly, test.epl does not do what you think it does. It should read:
[$ sub head $]
[- print "head\n"; -]
[$ endsub $]
Secondly, to use embperl files as objects I believe you need to be using
Embperl::Object which has additional configuration requirements. For
offline processing I would suggest that it may be overkill.
If all you want to do is execute a sub in another file then following
approaches both work with standard Embperl:
use Embperl;
Embperl::Execute( { inputfile => 'test.epl', sub => 'head' } );
Embperl::Execute( 'test.epl#head' );
Cheers,
Andrew
