ll-xist 3.5

Extensible HTML/XML generator, cross-platform templating language and various other tools

XIST provides an extensible HTML and XML generator. XIST is also a XML parser with a very simple and pythonesque tree API. Every XML element type corresponds to a Python class and these Python classes provide a conversion method to transform the XML tree (e.g. into HTML). XIST can be considered ‘object oriented XSLT’.

XIST also includes the following modules:

• ll.astyle can be used for colored terminal output (via ANSI escape sequences).

• ll.color provides classes and functions for handling RGB color values. This includes the ability to convert between different color models (RGB, HSV, HLS) as well as to and from CSS format, and several functions for modifying and mixing colors.

• ll.make is an object oriented make replacement. Like make it allows you to specify dependencies between files and actions to be executed when files don’t exist or are out of date with respect to one of their sources. But unlike make you can do this in a object oriented way and targets are not only limited to files, but you can implement e.g. dependencies on database records.

• ll.misc provides several small utility functions and classes.

• ll.sisyphus provides classes for running Python scripts as cron jobs.

• ll.daemon can be used on UNIX to fork a daemon process.

• ll.url provides classes for parsing and constructing RFC 2396 compliant URLs.

• ll.xpit is a module that makes it possible to embed Python expressions in text (as XML style processing instructions).

• ll.ul4c is compiler for a templating language with similar capabilities to Djangos templating language. UL4 templates are compiled to an internal bytecode format, which makes it possible to implement template renderers in other languages and makes the template code “secure” (i.e. template code can’t open or delete files).

• ll.xml_codec contains a complete codec for encoding and decoding XML.

Changes in 3.5 (released 12/05/2008)

• A new function json has been added to UL4: This function returns a JSON dump of the object passed in (this requires either simplejson or Python 2.6).

• The UL4 function csvescape has been renamed to csv.

• A new option --showregistration/-r has been added to make script.

• ll.make now supports Growl notifications on Mac OS X. To activate it set the LL_MAKE_GROWN environment variable to 1 or use the -g or --growl options.

• ll.make has a new action class JavascriptMinifyAction for minimizing Javascript source.

• ll.color.Color has been rewritten to create immutable objects with the components being 8 bit values (i.e. 0-255) instead of floating point values between 0 and 1. An alpha component has been added.

• A strong element has been added to the ll.xist.ns.doc` namespace.
