Re: [Boost-users] [Boost.FileSystem] File or Wildcards in Path? How-to do this?

That would definitely be very good if it could be added for the next major version of Boost.  It would be a relatively simple addition.  The file_iterator from Regex/v4 would need a few minor modifications to match the style of directory_iterator from Boost.FileSystem.  Or, in all honesty, the directory_iterator from Boost.Filesystem is very close, except that the code that takes action based on the assumption that it's a directory path adds '/*' to the end.  If the directory_iterator was configurable or there was a version (perhaps called file_iterator) that didn't append '/*' to the end of the directory lookup, then it would serve this purpose.

Thanks,

Lawrence

Well it's a common enough task that we really should do something about it:
the file-iterators in Boost.Regex are old pre-boost code used in a
now-deprecated part of the regex lib.  I guess what we really need is a new
library submission built on top of Boost.Filesystem.  Any takers?
