ll-xist 4.2

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

Latest Version: 5.27

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 and packages:

  • ll.ul4c is compiler for a cross-platform templating language with similar capabilities to Django’s templating language. UL4 templates are compiled to an internal 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).

    There are implementations for Python, Java, Javascript and PHP.

  • ll.ul4on provides functions for encoding and decoding a lightweight machine-readable text-based format for serializing the object types supported by UL4. It is extensible to allow encoding/decoding arbitrary instances (i.e. it is basically a reimplementation of pickle, but with string input/output instead of bytes and with an eye towards cross-plattform support).

    There are implementations for Python, Java, Javascript and PHP.

  • ll.orasql provides utilities for working with cx_Oracle:

    • It allows calling functions and procedures with keyword arguments.
    • Query results will be put into Record objects, where database fields are accessible as object attributes.
    • The Connection class provides methods for iterating through the database metadata.
    • Importing the modules adds support for URLs with the scheme oracle to ll.url.
  • 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Like make it allows you to specify dependencies between files and actions to be executed when files don’t exist or are out of date with respect to one of their sources.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.

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

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

  • ll.nightshade can be used to serve the output of PL/SQL functions/procedures with CherryPy.

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

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

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

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

Changes in 4.2 (released 10/22/2012)

  • UL4 templates now support list and dictionary comprehension as well as generator expressions.
  • A new UL4 function date has been added.
  • The UL4 method join no longer calls str on the items in the argument list.
  • The UL4 function format now supports a third argument: the language for formatting dates. So format(date(2012, 10, 10), '%A', 'de') outputs Mittwoch.
  • UL4 date objects now have a new week method. This method returns the week number of the year. It supports one argument: the weekday number (0 for Monday, … 6 for Sunday) that should be considered the start day of the week. All days in a new year preceding the first week start day are considered to be in week 0. The week start day defaults to 0 (Monday).
  • datetime.timedelta objects are now completely supported in UL4 templates: They can be created with the timedelta function and can be type tested for with istimedelta.
  • Added a new class ll.misc.monthdelta. monthdelta objects can be used to add months/years to a datetime.datetime or object. If the resulting day falls out of the range of valid days for the target month, the last day for the target month will be used instead.
  • monthdelta objects are now supported in UL4 templates: They can be created with the monthdelta function and can be type tested for with ismonthdelta.
