Version 0.3.0

Breaking changes

• Most built-in expression parsing functions/methods now expect the current Environment instance to be passed as the first argument.

Fixes

• Fixed {% for %} tag expressions with a comma between the iterable and limit, offset or reversed. Previously we were assuming a comma immediately following the iterable would mean we are iterating an array literal. We're also explicitly disallowing limit, offset and reversed arguments after an array literal.

Features

• Added optional filter argument validation at template parse time. (docs)
• Added lambda expressions as filter arguments. Both custom and built-in filters can accept arguments of the form <identifier> => <boolean expression> or (<identifier>, <identifier>) => <boolean expression>.
• Updated filters map, where, sort, sort_natural, uniq, compact and sum to accept lambda expression or string arguments.
• Added filters reject, has, find and find_index.

Documentation

• Added documentation for the json filter's optional indent argument.

Version 0.2.0

Features

• Added support for array literal syntax in for loop expressions. Previously array literals were only allowed in output statements and the assign tag. For example, {% for x in some.thing, 42, true %}.
• Add tokens for symbols ! and ?. These tokens are not used by any default Liquid expression, but can be used by custom tags.
