New submission from Erick Tryzelaar <[EMAIL PROTECTED]>:
As I mentioned on python-ideas, I my project needs to extend fnmatch to
support zsh-style globbing, where you can use brackets to designate
subexpressions. Say you had a directory structure like this:
foo/
foo.ext1
foo.ext2
bar/
foo.ext1
foo.ext2
The subexpressions will let you do patterns like this:
>>> glob.glob('foo/foo.{ext1,ext2}')
['foo/foo.ext1', 'foo/foo.ext2']
>>> glob.glob('foo/foo.ext{1,2}')
['foo/foo.ext1', 'foo/foo.ext2']
>>> glob.glob('{foo,bar}')
['bar', 'foo']
>>> glob.glob('{foo,bar}/foo*')
['bar/foo.ext1', 'bar/foo.ext2', 'foo/foo.ext1', 'foo/foo.ext2']
>>> glob.glob('{foo,bar}/foo.{ext*}')
['bar/foo.ext1', 'bar/foo.ext2', 'foo/foo.ext1', 'foo/foo.ext2']
>>> glob.glob('{f?o,b?r}/foo.{ext*}')
['bar/foo.ext1', 'bar/foo.ext2', 'foo/foo.ext1', 'foo/foo.ext2']
Would this be interesting to anyone else? It would unfortunately break
fnmatch since it currently treats {} as ordinary characters. It'd be
easy to work around that by adding a flag or using a different function
name though. Anyway, here's the patch against the head of py3k.
