digitalmars.D - dirEntries with ** (recursive) globbing

reply Timothee Cour <thelastmammoth gmail.com> writes:
Is there any plan to add recursive globs to dirEntries?

use case:

auto entries=dirEntry("foo/**/bar/*suffix/*.{d,di}", spanMode,
followSymlink)
will match for example:
foo/a/b/bar/somethingsuffix/file.d

Note, ** will match any number (>=0) of directories, whereas a single * is
non-recursive

(as found in some good shells and IIRC, later versions of python, etc).

note, in this case, spanMode could only be breadth or depth, not shallow as
the glob fully specifies depth.

I have partially working code (it doesn't handle {} but does handle * and
**), however it's not the most efficient, so was wondering.

There's an overload of "dirEntries" that takes a path and a pattern. It 
says the pattern is matched using std.path.globMatch. "globMatch" 
matches "*" recursively.

glob is non-recursive in D:

Furthermore, it would be very inefficient to filter out results given by
recursive dirEntries that match a glob pattern in general case (I can give
examples if needed)

Hmm, right, my bad.

I don't think there is any plan. These have traditionally been 
shell features, but probably useful in a programming library also.
