[Scons-users] changing the build directory

[Kenny, Jason L]

Honestly I am not sure why we need to do anything more complex than a simple recursive=True|False argument.

A agree that Glob needs help. I added an object called Pattern in My addon Parts. I keep trying to use Glob but it just does not work for me in cases when there is some directory structure.

I have to admit to not doing much with StackOverflow, the name says it all really ;-)

The emphasis in Python 3 is on being as lazy as possible so much more use of generators. If you want the data structure you ask for it explicitly. So for me:

	RGlob('*.groovy')

would return a generator, and:

	tuple(RGlob('*.groovy'))

would be the tuple derived from it.

An alternative design would be to use a recursive globbing syntax int he Glob and not have an RGlob at all. So, following Ant-like syntax:

	Glob('**/*.groovy')

would be the recursive form. This has the advantage of only needing changes to the Glob system. I am beginning to prefer this solution.
