In a nutshell

PXPerlWrap is a Perl wrapper. That is, it enables you embedding Perl in your C++ (MFC, but STL port planned) application, (DVD backup application for Mac) with minimum efforts. Enjoy the power of Perl through an intuitive set of C++ classes. Embed a world widely used scripting language without efforts: enjoy the power of Perl in minutes. Write high quality applications in seconds. Maintain them as easily. Enrich your applications of a scripting ability, extending to the infinity the possibilities for your end-users.

Special features: MT-safe object architecture, Persistent interpreters, transparent variables modification, UTF8 conversion options, (Free Video Converter Reviews) Unicode support.

Features:

• PXPerlWrap is a bi-directional wrapper. That is:
  • you can execute Perl code from your MFC application, and manipulate variables etc.
  • you can call your application, C++ functions and classes from within your Perl scripts.

  The first direction is achieved by PXPerlWrap. The second direction is achieved by SWIG, a free wrapper to several languages, on which you can find information here.

• PXPerWrap is a namespace containing an intuitive set of classes, multithread-safe:
  • CPerlInterpreter: represents a Perl interpreter, persistent. Several different interpreters can be loaded.
    • parse scripts;
    • run scripts, several times;
    • get a variable object to manipulate it or simply retrieve its value(s);
    • eval a piece of Perl quickly.
  • CScript: a script object. Each script keeps record of its own properties towards each interpreter.
    • load a plain text script;
    • load it from various sources: inline, file, URL, resource;
    • save it to file;
    • compile a plain script into byte code;
    • test a script;
    • reformat a script;
    • set its ARGV.
  • CPerlScalar: interfaces a Perl scalar variable.
    • string, integer, float assignment and arithmetic operations, as simple as s = "hello", s /= 1 and s += 1.0f, the way Perl supports it.
    • split it into a CPerlArray;
    • deal with UTF8 manually.
  • CPerlArray: interfaces a Perl array variable.
    • common CStringArray operations;
    • push, unshift, unshift in reverse order, push in reverse order, either a CPerlArray object, a CStringArray, or several elements from vararg;
    • join it into a CPerlScalar.
  • CPerlHash: interfaces a Perl hash variable.
    • common CMapStringToString operations;
    • Perl's each, keys, and values.
• The stdout and stderr standard streams can be redirected and sent to a window.
• PXPerlWrap supports UTF8 Perl encoded strings and offers various strategies in Unicode builds towards automatic strings conversion.
• Advanced error management
• ...

You said persistent interpreter?

The idea of the persistent interpreter was found in perlembed. It consists of parsing once a script which will take care of parsing and running itself other scripts. Each scripts are assigned a different package name. This way, cleaning the package associated with a script will clean the variables used by the script, and free the memory associated with them.

Benefits of persistent interpreters:

• if a module is used by several scripts, you can choose to load it once and it will affect all scripts. This prevent having to load a module each time a script is parsed. This can be a huge perfomance gain, if you consider theloading time of some modules.
• you can clean a script (the script namespace: variables etc.), hence freeing memory for other scripts,
• safety: die and exit won't make your application actually exit :) Besides, PXPerlWrap has an advanced error report and logging system.
