- Better expression usage. See Jexl. Access to java objects rather than just flat string properties.
Possible in myrmidon but will never be possible in ant1.x due to backwards compatability.
What has 'backward compatibility' to do with that ?
I actually have a working ProjectHelperImpl for ant1 that supports expersions in ${properties}, using ${lang:expression} style ( lang: is used to locate the evaluator ). I'm trying to integrate JXPath and few
other EL.
The only possible problem may be that someone may have a build file with a variable with that name. However the 'dynamic' properties will
be enabled only by setting a magic property, so the impact is absolutely zero.
Cool! :-)
Keep us informed :-)
If you get this out soon Ant 1.6 will have imports, antlibs, expressions! :-D
Antlib and imports can also be done using ProjectHelper hooks - and all that should work fine with ant1.5 ( at least that's my target ).
Done. There is a patch on Bugzilla :-) That's why I'm so interested in the outcome of your expression stuff :-D
The actual implementation is trivial ( ProjectHelper reads the XML and calls the ${} substitution ) - finding a good way to plug different evaluators and more important a good story for namespaces is the bigger problem.
( and of course, finding time ).
The code is already checked in proposals/sandbox/embed, look at RuntimeConfigurable2. ( most of the changes are to support sax2
attributes, the actual 'dynamic properties' is just the last method - I'm still working on the plugin mechanism ).
Can you keep me/us more informed on the actual state and proceedings?
It would be swell, I could integrate the import proposal in that one and help work on it.
