[REBOL] Re: Filtering files in directories.
From: chris:ross-gill at: 2-Jan-2003 14:42
Hi Ed,
Ok, this is neither pattern matching (works by suffix) nor does it bypass
the need to load a full list of files (not sure there's any other way to do
it), but it can be hacked relatively easily for your own needs.
Usage:
>> read-filter %./ %.jpg
>> read-filter %./ [%.html %.r]
It also retains directories, but that could be dropped from the source.
