Classes

require('perl').Perl

var perl = new Perl()

Create new instance of Perl.

var retval = perl.evaluate(Str code)

evaluate the perl code and get a return value.

var klass = perl.getClass(Str name)

Get a class object(Instance of PerlClass) from perl.

var klass = Perl.blessed(obj)

Same as Scalar::Util::blessed.

var val = perl[funcname]

Get a PerlMethod object.

require('perl-simple').PerlObject

var val = obj[funcname]

Get a PerlMethod object.

require('perl-simple').PerlClass

You can get a instance of this class by Perl#getClass.

var val = klass[funcname]

Get a PerlMethod object.

require('perl-simple').PerlMethod

var val = method()

Call perl5 function and get a return value in scalar context. You get a exception when Perl5 throws exception.

var val = method.callList()

Same as above, but callList calls function in list context.

Installation

node-perl requires a perl5 binary built with -fPIC and -Duseshrplib. Normally, linux distribution's system perl is usable.

You can build a perl binary for node-perl with perlbrew command.

$ PERLBREW_CONFIGURE_FLAGS=-de perlbrew install perl-5.16.1 -Duseshrplib -Duseithreads -Dusethreads -Accflags='-fPIC' -nv
$ perlbrew use perl-5.16.1

On OSX

If you got a error while loading libperl.dylib, please set a DYLD_LIBRARY_PATH to perl5 library path.

Notes

  • The calls to Perl are synchronous ones.
