In a nutshell

PXPerlWrap is a Perl wrapper. That is, it enables you embedding Perl in your C++ (MFC, but STL port planned) application, 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, 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.
