@StefanKarpinski What do you think we should do with this one, given all the file API refactoring?

[StefanKarpinski]

I'll include this or something like it in the refactor.

[johnmyleswhite]

We should definitely work on something like this, since it would also subsume the FileFind package I created.

@StefanKarpinski What's the status of this. Was this addressed or is this still relevant?

[johnmyleswhite]

I'd really like to see this added.

[timholy]

Bump. @StefanKarpinski, your input needed here.

[johnmyleswhite]

I really want to see this (or something like it) merged into Base.

[StefanKarpinski]

@JeffBezanson, let's discuss this and try to figure out what API tweaks this needs.

[StefanKarpinski]

This feels a bit too complicated for Base. If you need to iterate directories and files in some order, you can just write one of those loops – it's not all that hard. If we can come up with a distilled version of what Base could provide in terms of file searching and/or walking, that can be considered for inclusion in base, but I'm just not comfortable.

Sounds reasonable, and good to have a decision.

We could have a "filesystem extras" package, if someone is interested in starting one.
