Subject Re: Fw: Java Add On for Ant to fix filename + extension case issues
Date Thu, 09 Oct 2003 15:53:30 GMT
Paul,

This task would be improved by making the attributes use meaningful
names rather than numbers (as it is, every usage of the task in a build
file would probably have to be commented to state what is being done).

Ant provides a useful enumerated type mechanism for just this purpose,
called EnumeratedAttribute. Take a look at the source for Echo for an
example of its use.

Phil :n)
