----------------------------------
Summary: Support for dynamic scripting in jexl scripts
Key: JEXL-200
URL: https://issues.apache.org/jira/browse/JEXL-200
Project: Commons JEXL
Issue Type: New Feature
Affects Versions: 3.0
Reporter: Dmitri Blinov
Priority: Minor
Allow for dynamically defined functions inside a script where the definition of
the function comes from a string expression, for example:
{code}
def x(y) = "return y+2";
{code}
the defined function should be accessable after its definition is successfully
parsed as ordinary function, and can be evaluated in the current context.
{code}
if (x(40) eq 42) {...
{code}
I think the idea of dynamic script evaluation is not unusual, and though to
some extent can be implemented via side-added functions like *eval(expr)* a
dedicated syntax for this will benefit from the simplicity of ordinal functions
and the ability to control mapping of the arguments between a caller and the
defined function.
