The Commons JEXL team is pleased to announce the commons-jexl-2.0 release!
JEXL is an Expression Language supporting most of the constructs in the JSTL
Expression Language,
along with some additional extensions. As a library, it is intended to
facilitate the implementation
of dynamic and scripting features in applications and frameworks.
New Features:
Assignment expression: a = b (and a.b.c = d). Issue: JEXL-27. Thanks to
Weikuo Liaw.
* Assigns a variable (ant-like variable or bean-property)
Ternary operator expression: a ? b : c (and a ?: c). Issue: JEXL-19. Thanks
to Jesse Glick.
* The usual inline conditional shortcut and its 'Elvis' form (a ?: b
evaluates as a ? a : b)
Constructor call expression: new('my.class.name', arguments...)
* Creates a new instance of a class using the most appropriate
constructor according
to the actual arguments
Function namespace: ns:func(arguments...) Issue: JEXL-15. Thanks to Paul
Libbrecht.
* A function namespace allows the use of class or instance methods in
function calls
UnifiedJEXL
* Adds ${...} and #{...} JSP/EL syntax support on top of the JexlEngine
JSR-223 support. Issue: JEXL-63. Thanks to Sebastian Bazley.
* Implement JSR-223 Scripting Engine for JEXL script (need BSF-3.0 on
Java < 6)
Error and exception handling. Issue: JEXL-10, JEXL-11. Thanks to Paul
Libbrecht.
* Configuring the leniency and verbosity of the Jexl engine allows user
control over the
error handling policy
Support Unicode escapes in string literals and quote escaping. Issue:
JEXL-17. Thanks to Nestor Urquiza.
* 'foo\u0020bar\'quux'
Perl-like regular-expression operators. Issue: JEXL-46. Thanks to Alfred
Reibenschuh.
Fixed Bugs:
* Allow single-line comments with // Issue: JEXL-47. Thanks to Sebastian
Bazley.
* Comments don't allow double-quotes Issue: JEXL-44. Thanks to Sebastian
Bazley.
* Call method with varargs Issue: JEXL-25. Thanks to Marek Lewczuk.
* BigDecimal values are treated as Long values which results in loss of
precision Issue: JEXL-32. Thanks to Kedar Dave.
* Remove unnecessary throws Exception from various classes Issue: JEXL-33.
* Div operator does not do integer division Issue: JEXL-50. Thanks to
Sebastian Bazley.
* Inconsistent behaviour of arithmetical operations Issue: JEXL-87. Thanks
to Sebastian Bazley.
* Operator overloading / hooks on operator processing Issue: JEXL-21.
Thanks to AC.
