> [jexl] Needs definable functions
> --------------------------------
>
> Key: JEXL-15
> URL: http://issues.apache.org/jira/browse/JEXL-15
> Project: Commons JEXL
> Issue Type: Improvement
> Environment: Operating System: other
> Platform: Other
> Reporter: Paul Libbrecht
> Priority: Minor
> Fix For: 2.0
>
>
> Currently, in Jexl, the only way to add a functionality is to define a
> variable.
> Typically this is done in a separate environment... e.g. in jelly's j:new,
> j:set or...
> Using this, one can define, say, "a" then invoke "a.doSomething(withThat)".
> It would be nice to allow adding methods, e.g. "doSomething" to be invoked
> without any object.
> This way I could just say "doSomething".
> Examples of usage include:
> - add some mathematical functions to make jexl full featured mathematically
> (e.g. "abs", "exp",
> "atan")
> - add some "general purpose utilitites" (e.g. "tokenize(aString)",
> "toString(xx)", or
> "relativeUrl(baseUrl, relPath)")
> - thereby become more compatible with JSP (i've been told)
> This should promote general usage of such functions availability.
> In some situations this would help a lot. For example in maven where I too
> often still see
> srcFile="${baseDIr+pathToResource}" which prevents any overridability.
