perl-path-iterator-rule 1.014

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.

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.
