* made macros return their value instead of echoing directly (fixes calling a macro in sandbox mode)
* added the "from" tag to import macros as functions
* added support for functions (a function is just syntactic sugar for a getAttribute() call)
* made macros callable when sandbox mode is enabled
* added an exception when a macro uses a reserved name
* the "default" filter now uses the "empty" test instead of just checking for null
* added the "empty" test
* 0.9.10 (2010-12-16)
Backward incompatibilities:
* The Escaper extension is enabled by default, which means that all displayed
variables are now automatically escaped. You can revert to the previous
behavior by removing the extension via $env->removeExtension('escaper')
or just set the 'autoescape' option to 'false'.
* removed the "without loop" attribute for the "for" tag (not needed anymore
as the Optimizer take care of that for most cases)
* arrays and hashes have now a different syntax
* arrays keep the same syntax with square brackets: [1, 2]
* hashes now use curly braces (["a": "b"] should now be written as {"a": "b"})
* support for "arrays with keys" and "hashes without keys" is not supported anymore ([1, "foo": "bar"] or {"foo": "bar", 1})
* the i18n extension is now part of the Twig Extensions repository
Changes:
* added the merge filter
* removed 'is_escaper' option for filters (a left over from the previous version) -- you must use 'is_safe' now instead
* fixed usage of operators as method names (like is, in, and not)
* changed the order of execution for node visitors
* fixed default() filter behavior when used with strict_variables set to on
* fixed filesystem loader compatibility with PHAR files
* enhanced error messages when an unexpected token is parsed in an expression
* fixed filename not being added to syntax error messages
* added the autoescape option to enable/disable autoescaping
* removed the newline after a comment (mimics PHP behavior)
* added a syntax error exception when parent block is used on a template that does not extend another one
* made the Escaper extension enabled by default
* fixed sandbox extension when used with auto output escaping
* fixed escaper when wrapping a Twig_Node_Print (the original class must be preserved)
* added an Optimizer extension (enabled by default; optimizes "for" loops and "raw" filters)
* added priority to node visitors
* 0.9.9 (2010-11-28)
Backward incompatibilities:
* the self special variable has been renamed to _self
* the odd and even filters are now tests:
{{ foo|odd }} must now be written {{ foo is odd }}
* the "safe" filter has been renamed to "raw"
* in Node classes,
sub-nodes are now accessed via getNode() (instead of property access)
attributes via getAttribute() (instead of array access)
* the urlencode filter had been renamed to url_encode
* the include tag now merges the passed variables with the current context by default
(the old behavior is still possible by adding the "only" keyword)
* moved Exceptions to Twig_Error_* (Twig_SyntaxError/Twig_RuntimeError are now Twig_Error_Syntax/Twig_Error_Runtime)
* removed support for {{ 1 < i < 3 }} (use {{ i > 1 and i < 3 }} instead)
* the "in" filter has been removed ({{ a|in(b) }} should now be written {{ a in b }})
Changes:
* added file and line to Twig_Error_Runtime exceptions thrown from Twig_Template
* changed trans tag to accept any variable for the plural count
* fixed sandbox mode (__toString() method check was not enforced if called implicitly from complex statements)
* added the ** (power) operator
* changed the algorithm used for parsing expressions
* added the spaceless tag
* removed trim_blocks option
* added support for is*() methods for attributes (foo.bar now looks for foo->getBar() or foo->isBar())
* changed all exceptions to extend Twig_Error
* fixed unary expressions ({{ not(1 or 0) }})
* fixed child templates (with an extend tag) that uses one or more imports
* added support for {{ 1 not in [2, 3] }} (more readable than the current {{ not (1 in [2, 3]) }})
* escaping has been rewritten
* the implementation of template inheritance has been rewritten
(blocks can now be called individually and still work with inheritance)
* fixed error handling for if tag when a syntax error occurs within a subparse process
* added a way to implement custom logic for resolving token parsers given a tag name
* fixed js escaper to be stricter (now uses a whilelist-based js escaper)
* added the following filers: "constant", "trans", "replace", "json_encode"
* added a "constant" test
* fixed objects with __toString() not being autoescaped
* fixed subscript expressions when calling __call() (methods now keep the case)
* added "test" feature (accessible via the "is" operator)
* removed the debug tag (should be done in an extension)
* fixed trans tag when no vars are used in plural form
* fixed race condition when writing template cache
* added the special _charset variable to reference the current charset
* added the special _context variable to reference the current context
* renamed self to _self (to avoid conflict)
* fixed Twig_Template::getAttribute() for protected properties
* 0.9.8 (2010-06-28)
Backward incompatibilities:
* the trans tag plural count is now attached to the plural tag:
old: `{% trans count %}...{% plural %}...{% endtrans %}`
new: `{% trans %}...{% plural count %}...{% endtrans %}`
* added a way to translate strings coming from a variable ({% trans var %})
* fixed trans tag when used with the Escaper extension
* fixed default cache umask
* removed Twig_Template instances from the debug tag output
* fixed objects with __isset() defined
* fixed set tag when used with a capture
* fixed type hinting for Twig_Environment::addFilter() method
* 0.9.7 (2010-06-12)
Backward incompatibilities:
* changed 'as' to '=' for the set tag ({% set title as "Title" %} must now be {% set title = "Title" %})
* removed the sandboxed attribute of the include tag (use the new sandbox tag instead)
* refactored the Node system (if you have custom nodes, you will have to update them to use the new API)
* added self as a special variable that refers to the current template (useful for importing macros from the current template)
* added Twig_Template instance support to the include tag
* added support for dynamic and conditional inheritance ({% extends some_var %} and {% extends standalone ? "minimum" : "base" %})
* added a grammar sub-framework to ease the creation of custom tags
* fixed the for tag for large arrays (some loop variables are now only available for arrays and objects that implement the Countable interface)
* removed the Twig_Resource::resolveMissingFilter() method
* fixed the filter tag which did not apply filtering to included files
* added a bunch of unit tests
* added a bunch of phpdoc
* added a sandbox tag in the sandbox extension
* changed the date filter to support any date format supported by DateTime
