iterative, recursive file finder
Path::Iterator::Rule iterates over files and directories to identify ones matching a user-defined set of rules. The API is based heavily on File::Find::Rule, but with more explicit distinction between matching rules and options that influence how directories are searched. A Path::Iterator::Rule object is a collection of rules (match criteria) with methods to add additional criteria. Options that control directory traversal are given as arguments to the method that generates an iterator. . Here is a summary of features for comparison to other file finding modules: * provides many "helper" methods for specifying rules * offers (lazy) iterator and flattened list interfaces * custom rules implemented with callbacks * breadth-first (default) or pre- or post-order depth-first searching * follows symlinks (by default, but can be disabled) * directories visited only once (no infinite loop; can be disabled) * doesn't chdir during operation * provides an API for extensions . As a convenience, the PIR module is an empty subclass of this one that is less arduous to type for one-liners.
