12 .. admonition:: Backwards Incompatible Changes
14 - `call` is a keyword now
15 - the internal parser AST changed
16 - `extends` must be the first tag in a template
17 - the tuple literal yields tuples now, instead of lists.
19 - environments now have a `translator_factory` parameter that allows
20 to change the translator without subclassing the environment.
22 - fixed bug in buffet plugin regarding the package loader
24 - once again improved debugger.
26 - added `groupby` filter.
28 - added `sameas` test function.
30 - standalone parser. Jinja does not use the python parser any more and will
31 continue having the same semantics in any future python versions. This
32 was done in order to simplify updating Jinja to 2.6 and 3.0 and to support
35 - added support for ``expr1 if test else expr2`` (conditional expressions)
37 - ``foo.0`` as alias for ``foo[0]`` is possible now. This is mainly for
40 - the filter operators has a much higher priority now which makes it
41 possible to do ``foo|filter + bar|filter``.
43 - new AST. the return value of `Environment.parse` is now a Jinja AST and not
44 a Jinja-Python AST. This is also the only backwards incompatible change but
45 should not affect many users because this feature is more or less
46 undocumented and has few use cases.
48 - tuple syntax returns tuples now and not lists any more.
50 - the print directive and ``{{ variable }}`` syntax now accepts and implicit
51 tuple like the `for` and `cycle` tags. (``{{ 1, 2 }}`` is an implicit alias
52 for ``{{ (1, 2) }}` like ``{% for a, b in seq %}`` is for
53 ``{% for (a, b) in seq %}``.
55 - tests called with *one* parameter don't need parentheses. This gives a more
56 natural syntax for the `sameas` test and some others:
57 ``{{ foo is sameas bar }}`` instead of ``{{ foo is sameas(bar) }}``. If you
58 however want to pass more than one argument you have to use parentheses
59 because ``{{ foo is sometest bar, baz }}`` is handled as
60 ``{{ (foo is sometest(bar), baz) }}``, so as tuple expression.
62 - removed support for octal character definitions in strings such as
63 ``'\14'``, use ``'\x0c'`` now.
65 - added regular expression literal. ``@/expr/flags`` equals
66 ``re.compile(r'(?flags)expr')``. This is useful for the `matching` test and
69 - added set literal. We do not use python3's {1, 2} syntax because
70 this conflicts with the dict literal. To be compatible with the regex
71 literal we use ``@(1, 2)`` instead.
73 - fixed bug in `get_attribute` that disallowed retreiving attributes of objects
74 without a `__class__` such as `_sre.SRE_Pattern`.
76 - addded `django.contrib.jinja` which provides advanced support for django.
77 (thanks Bryan McLemore)
79 - debugger is now able to rewrite the whole traceback, not only the first
80 frame. (requires the optional debugger c module which is compiled
81 automatically on installation if possible)
83 - if the set that is postfixed with a bang (!) it acts like the python 3
84 "nonlocal" keyword. This means that you can now override variables
85 defined in the outer scope from within a loop.
87 - ``foo ~ bar`` is now a simpler alternative to ``foo|string + bar|string``
89 - `PackageLoader` can now work without pkg_resources too
91 - added `getattribute` and `getitem` filter.
93 - added support for the `pretty` library.
95 - changed the way the `MemcachedLoaderMixin` creates the class so that it's
96 possible to hook your own client in.
101 (codename: sinka, released Jun 1, 2007)
103 - blocks now support ``{{ super() }}`` to render the parent output.
105 - debugging system improved, smaller filesize for the cached files.
106 Debugging works now well for any module using linecache.
108 - ``{{ debug() }}`` can now be used to get a list of filters and
111 - the template lexer keeps not track of brace, parenthesis and
112 bracket balance in order to not break variable tags apart if they
113 are configured to look like this: ``${expr}``. This also fixes
114 the problem with nested dicts in variable expressions.
116 - it's now possible to configure the variable blocks to look the
117 same as the block delimiters. Thus you can set the syntax to something
118 like ``{ / }`` for both blocks and variables.
120 - added whitespace management system for the template designer.
122 - some small bugfixes.
124 - improved security system regarding function calls and variable
125 assignment in for loops.
127 - added `lipsum` function to generate random text.
129 - strings without unicode characters are processed as binary strings now
130 to workaround problems with `datetime.strftime` which only accepts
133 - it's now possible to use newlines in string literals
135 - developer friendly traceback is now toggleable
137 - the variable failure is now pluggable by replacing the undefined
138 singleton for an environment instance
140 - fixed issue with old-style classes not implementing `__getitem__`
141 (thanks to Axel Böhm for discovering that bug)
143 - added a bunch of new docstrings to the Jinja classes. Makes fun now to
146 - fixed severe memcaching bug. Formerly it wasn't possible to use memcaching
147 without enabling disk cache.
149 - fixed a bug that allowed users to override the special names `_`, `true` etc.
151 - added `batch` and `slice` filters for batching or slicing sequences
153 - added `sum`, `abs`, `round` and `sort` filters. This fixes #238
155 - added `striptags` and `xmlattr` filters for easier SGML/XML processing
157 - the trans tag does not need explicit naming for variables with the same
158 name any more. You can now use ``{% trans foo %}`` instead of the verbose
159 version ``{% trans foo=foo %}``.
161 - reimplemented Buffet plugin so that it works at least for pylons
163 - added `Environment.get_translations_for_string`
165 - fixed a bug in the parser that didn't unescape keyword arguments. (thanks
166 to Alexey Melchakov for reporting)
168 - You can now use the environment to just tokenize a template. This can
169 be useful for syntax highlighting or other purposes.
171 - added optional C-implementation of the context baseclass.
173 - you can now use optional parentheses around macro defintions. Thus it's
174 possible to write ``{% macro foo(a, b, c) %}`` instead of ``{% macro
177 - additional macro arguments now end up in `varargs`.
179 - implemented the `{% call %}` block. `call` and `endcall` can still be used
180 as identifiers until Jinja 1.3
182 - it's now possible to stream templates.
184 - fixed a corner case when defining a block inside of a condition
186 - the cached loader mixin is now able to cache multiple templates from
187 different loaders in the same cache folder.
189 - Translatable strings returned by ``_()`` will leave their string formatting
190 signs untouched. Thanks to Stefan Ebner for reporting.
192 - ``{% block name "data" %}`` is now an alias for
193 ``{% block name %}data{% endblock %}``. Note that the second argument can
194 be an expression. As soon as you specify an expression as second argument
195 the closing tag has to be omitted.
197 - It's now possible to iterate over iterators additionally to sequences.
198 If the iterator is inifite it will crash however, so makes sure you don't
199 pass something like that to a template!
201 - added `rendetemplate` to render included templates in an isolated
202 environment and get the outout back.
204 - added `simplefilter` decorator.
206 - improved ChoiceLoader error reporting (thanks to Bryan McLemore)
208 - fixed extended slicing
210 - reworked loader layer. All the cached loaders now have "private" non cached
211 baseclasses so that you can easily mix your own caching layers in.
213 - added `MemcachedLoaderMixin` and `MemcachedFileSystemLoader` contributed
