The {% if %} tag provides all features of these tags.
Since Django 1.2 (May 17, 2010), the docs have hinted that
{% ifequal %} and {% ifnotequal %} will be deprecated in a future
Django version. Time to make it official.
* Converted the ``libraries`` and ``builtins`` globals of
``django.template.base`` into properties of the Engine class.
* Added a public API for explicit registration of libraries and builtins.
This patch does three major things:
* Merges the django.template.debug implementation into django.template.base.
* Simplifies the debug implementation.
The old implementation copied debug information to every token and node.
The django_template_source attribute was set in multiple places, some
quite hacky, like django.template.defaulttags.ForNode.
Debug information is now annotated in two high-level places:
* Template.compile_nodelist for errors during parsing
* Node.render_annotated for errors during rendering
These were chosen because they have access to the template and context
as well as to all exceptions that happen during either the parse or
render phase.
* Moves the contextual line traceback information creation from
django.views.debug into django.template.base.Template. The debug views now
only deal with the presentation of the debug information.
Since this package is going to hold both the implementation of the Django
Template Language and the infrastructure for Multiple Template Engines,
it should be untied from the DTL as much as possible within our
backwards-compatibility policy.
Only public APIs (i.e. APIs mentioned in the documentation) were left.
