Python Code Object Utilities

Mon, 20 Nov 2006 01:34:47 +0200

This library provides a simple interface for changing the behavior of existing function/method objects. Download: pycodeutils.zip (License: MIT License, see file LICENSE in the distribution) Usage The behavior of a function/method object is changed by replacing its associated code object with a new one. The new code object delegates the execution to a given user-defined function (delegatee). The arguments as well as the original code are passed to the delegatee. So it is possible to either e…

RELAX NG with Content Classes

Tue, 21 Nov 2006 03:52:50 +0200

Version: 2006-11-20 Author: Oliver Horn This document describes ERNC, a syntactic extension of RELAX NG‘s Compact Syntax (RNC). ERNC introduces a lightweight syntax to make the definition of so-called “content classes” more convenient. Note that all extensions are just syntactic sugar. Every ERNC grammar can be transformed into a pure RELAX NG grammar; a simple processor is available for .

Syntax Tokenizer Extension for Saxon

Sun, 19 Nov 2006 22:23:50 +0200

This extension for Saxon 6.5 provides an XSLT extension function for tokenizing programming code fragments. The extension function can be used to perform on-fly syntax highlighting during the transformation process. How does it works? The function returns an interim node-set containing a tokenized representation of the code. The stylesheet can then process this node-set, e.g. to generate formatted, syntax-highlighted output.
