"CodeWorker" is a scripting language that is intended to assist the developer in writing source code or documentation. It is distributed under the ''GNU Lesser General Public License'' at the URL "http://www.codeworker.org". This application is a 'semiskilled worker' specialized in generating repetitive and tedious source code and text. The way it proceeds is: - to acquire modeling data from an extended BNF parser interpreter, - to handle parse trees well adapted to represent a design and easy to walk, - to generate source code via kinds of 'coding patterns'. It carries out these tasks via a scripting language, whose syntax is particularly studied for: - describing an extended BNF: the syntax looks like the one commonly admitted for BNF, - providing all functions, statements and procedures that are expected for a procedural language, - defining 'coding patterns': the principle is the same as XSLT, JSP, PHP and so on, but no target language is imposed (nor XML neither HTML neither JAVA ...). The predicated-LL(k) grammar is powerful enough to allow parsing any kind of file (C++, 'Petal' file of Rational ROSE, LaTeX, ...). The software doesn't care of parochialism about languages and can generate JAVA code as well as C++ or LaTeX or your own output file, whatever it is. Generic programming and implementation of coding patterns become very easy. The documentation ("http://www.codeworker.org/CodeWorker.pdf") is written in "frenglish" (easy to understand for French people, but very far from Shakespeare!). I'll be very glad to take your remarks into account (email "codeworker@free.fr") to improve it!
