Parse::Yapp provides a set of modules and a frontend to generate Perl OO LALR(1) parsers. It can input clean yacc or bison grammars. The generated parsers are fast, being based, like yacc, on building Deterministic Finite Automata (DFA) and moving through a set of states using Deterministic Push Down Automata (DPDA) derived from the DFA to match the input stream tokens.
SWIG is a software development tool that connects programs written in C and C++ with a variety of high-level programming languages. SWIG is primarily used with common scripting languages such as Perl, PHP, Python, Tcl/Tk, and Ruby, however the list of supported languages also includes non-scripting languages such as C#, Common Lisp (CLISP, Allegro CL, UFFI), Java, Modula-3, OCAML, Octave, and R. Also several interpreted and compiled Scheme implementations (Guile, MzScheme, Chicken) are supported. SWIG is most commonly used to create high-level interpreted or compiled programming environments, user interfaces, and as a tool for testing and prototyping C/C++ software. SWIG can also export its parse tree in the form of XML and Lisp s-expressions.
The GCC XML Tree Node Introspector project consists of a patch to the gcc compiler to output the internal compiler tree nodes in RDF/XML and programs to process that RDF/XML. The tree nodes are complex data structures which represent the source code inside the compiler. Through these tree nodes, users are able to extract information from their programs that would be otherwise very difficult to obtain. Modules exist to store these nodes in Redland RDF using a Berkley database. The long-term goal of the project is create a high-level API that will make the programmatic manipulation of programs easier than it is now.
CASM is an offline content management tool. It is ideal for creating and maintaining dynamic or static Web, WAP, or XML sites. CASM is implemented as an integrated command-line application which contains the Content Assembling Language compiler, an optimizer for HTML, CSS, and XML, HTML tidy integration, a powerful site file structure builder, and more. Content Assmebling Language (CAL) is a markup language designed to separate site content from display properties. CAL has a comfortable templating mechanism, if-then-else structure, variable substitution, file including, recordset handling, looping functions, and embedded Perl scripting.
Stunnix Perl-Obfus is a unique solution for protecting your valuable intellectual property from possible Perl source code piracy/studying/rework. It's an advanced and extremely reliable obfuscator for the Perl source code. It converts the Perl source files (.pl and .pm) into highly mangled and obfuscated forms, making them extremely difficult to study, analyse, reuse, or re-work for competitors or customers, while fully retaining functionality of the original source code. It's not a compiler to machine code, and the obfuscated form will still be the usual Perl source code, and so will work on all platforms the original source worked on.
