Jinja2 Changelog¶
Version 2.2¶
(codename unknown, release date yet unknown)
- Include statements can now be marked with ignore missing to skip non existing templates.
- Priority of not raised. It’s now possible to write not foo in bar as an alias to foo not in bar like in python. Previously the grammar required parentheses (not (foo in bar)) which was odd.
- Fixed a bug that caused syntax errors when defining macros or using the {% call %} tag inside loops.
- Fixed a bug in the parser that made {{ foo[1, 2] }} impossible.
- Made it possible to refer to names from outer scopes in included templates that were unused in the callers frame (#327)
- Fixed a bug that caused internal errors if names where used as iteration variable and regular variable after the loop if that variable was unused before the loop. (#331)
- Added support for optional scoped modifier to blocks.
- Added support for line-comments.
Version 2.1.1¶
(Bugfix release)
- Fixed a translation error caused by looping over empty recursive loops.
Version 2.1¶
(codename Yasuzō, released on November 23rd 2008)
- fixed a bug with nested loops and the special loop variable. Before the change an inner loop overwrote the loop variable from the outer one after iteration.
- fixed a bug with the i18n extension that caused the explicit pluralization block to look up the wrong variable.
- fixed a limitation in the lexer that made {{ foo.0.0 }} impossible.
- index based subscribing of variables with a constant value returns an undefined object now instead of raising an index error. This was a bug caused by eager optimizing.
- the i18n extension looks up foo.ugettext now followed by foo.gettext if an translations object is installed. This makes dealing with custom translations classes easier.
- fixed a confusing behavior with conditional extending. loops were partially executed under some conditions even though they were not part of a visible area.
- added sort filter that works like dictsort but for arbitrary sequences.
- fixed a bug with empty statements in macros.
- implemented a bytecode cache system. (Bytecode Cache)
- the template context is now weakref-able
- inclusions and imports “with context” forward all variables now, not only the initial context.
- added a cycle helper called cycler.
- added a joining helper called joiner.
- added a compile_expression method to the environment that allows compiling of Jinja expressions into callable Python objects.
- fixed an escaping bug in urlize
Version 2.0¶
(codename jinjavitus, released on July 17th 2008)
the subscribing of objects (looking up attributes and items) changed from slightly. It’s now possible to give attributes or items a higher priority by either using dot-notation lookup or the bracket syntax. This also changed the AST slightly. Subscript is gone and was replaced with Getitem and Getattr.
For more information see the implementation details.
added support for preprocessing and token stream filtering for extensions. This would allow extensions to allow simplified gettext calls in template data and something similar.
added missing support for implicit string literal concatenation. {{ "foo" "bar" }} is equivalent to {{ "foobar" }}
else is optional for conditional expressions. If not given it evaluates to false.
improved error reporting for undefined values by providing a position.
filesizeformat filter uses decimal prefixes now per default and can be set to binary mode with the second parameter.
fixed bug in finalizer
