0.5.0 (2012-04-03)

This version represents a major rewrite and refactoring of the code base that also adds features and fixes many bugs. All functionality and nearly all unit tests have been preserved. However, some backwards incompatible changes to the API have been made.

Below is a selection of some of the changes (not exhaustive).


  • Pystache now passes all tests in version 1.0.3 of the Mustache spec. [pvande]
  • Removed View class: it is no longer necessary to subclass from View or from any other class to create a view.
  • Replaced Template with Renderer class: template rendering behavior can be modified via the Renderer constructor or by setting attributes on a Renderer instance.
  • Added TemplateSpec class: template rendering can be specified on a per-view basis by subclassing from TemplateSpec.
  • Introduced separation of concerns and removed circular dependencies (e.g. between Template and View classes, cf. issue #13).
  • Unicode now used consistently throughout the rendering process.
  • Expanded test coverage: nosetests now runs doctests and ~105 test cases from the Mustache spec (increasing the number of tests from 56 to ~315).
  • Added a rudimentary benchmarking script to gauge performance while refactoring.
  • Extensive documentation added (e.g. docstrings).

Other changes:

  • Added a command-line interface. [vrde]
  • The main rendering class now accepts a custom partial loader (e.g. a dictionary) and a custom escape function.
  • Non-ascii characters in str strings are now supported while rendering.
  • Added string encoding, file encoding, and errors options for decoding to unicode.
  • Removed the output encoding option.
  • Removed the use of markupsafe.

Bug fixes:

  • Context values no longer processed as template strings. [jakearchibald]
  • Whitespace surrounding sections is no longer altered, per the spec. [heliodor]
  • Zeroes now render correctly when using PyPy. [alex]
  • Multline comments now permitted. [fczuardi]
  • Extensionless template files are now supported.
  • Passing **kwargs to Template() no longer modifies the context.
  • Passing **kwargs to Template() with no context no longer raises an exception.
