[Scons-users] Oh dear, Winder has been an idiot…

[Tom Tanner (BLOOMBERG/ LONDON)]

To be fair, it's not unreasonable to expect to be able to do things with File objects. I keep running across situations where I have to Fileify or stringify something to get things to work as expected.

I probably qualify as a day 3 noob too, and at this rate, will do for a while yet

Gary, Andrew,

Thanks muchly for speedy and frequent responses. I have discovered I
have been making a n00b "day 3" error, and that everything works exactly
as wanted. There is no need for the str stuff, so hopefully Andrew can
simplify his codes.

sources = Glob('*.cc')
special = File('flob.cc')
source.remove(special)

works exactly as required.

Of course this is true if and only if File('flob.cc') is a reference to
the same object created in the list by Glob('*.cc') which appears to be
true at present. But is this a pure fluke or deep magic of SCons?

The issue here is that SCons.Node.FS.File does not define __eq__,
__ne__, __hash__ and so is reliant on the identity equality that is the
default.

I am embarrassed and will now crawl into a whole and wish for the thread
to be removed from the Internet history and everyone's memory.
