Summary : Nice wrapper for File::Find ala find(1)
Description :
\'File::Find\' is great, but constructing the \'wanted\' routine can sometimes
be a pain. This module provides a \'wanted\'-writer, using syntax that is
directly mappable to the _find_ command\'s syntax.

Also, I find myself (heh) frequently just wanting the list of names that
match. With \'File::Find\', I have to write a little accumulator, and then
access that from a closure. But with \'File::Finder\', I can turn the problem
inside out.

A \'File::Finder\' object contains a hash of \'File::Find\' options, and a
series of steps that mimic _find_\'s predicates. Initially, a \'File::Finder\'
object has no steps. Each step method clones the previous object\'s options
and steps, and then adds the new step, returning the new object. In this
manner, an object can be grown, step by step, by chaining method calls.
Furthermore, a partial sequence can be created and held, and used as the
head of many different sequences.

For example, a step sequence that finds only files looks like:

my $files = File::Finder->type(\'f\');

Here, \'type\' is acting as a class method and thus a constructor. An
instance of \'File::Finder\' is returned, containing the one step to verify
that only files are selected. We could use this immediately as a
\'File::Find::find\' wanted routine, although it\'d be uninteresting:

use File::Find;
find($files, \"/tmp\");

Calling a step method on an existing object adds the step, returning the
new object:

my $files_print = $files->print;

And now if we use this with \'find\', we get a nice display:

find($files_print, \"/tmp\");

Of course, we didn\'t really need that second object: we could have
generated it on the fly:

find($files->print, \"/tmp\");

\'File::Find\' supports options to modify behavior, such as depth-first
searching. The \'depth\' step flags this in the options as well:

my $files_depth_print = $files->depth->print;

However, the \'File::Finder\' object needs to be told explictly to generate
an options hash for \'File::Find::find\' to pass this information along:

find($files_depth_print->as_options, \"/tmp\");

A \'File::Finder\' object, like the _find_ command, supports AND, OR, NOT,
and parenthesized sub-expressions. AND binds tighter than OR, and is also
implied everywhere that it makes sense. Like _find_, the predicates are
computed in a \"short-circuit\" fashion, so that a false to the left of the
(implied) AND keeps the right side from being evaluated, including entire
parenthesized subexpressions. Similarly, if the left side of an OR is
false, the right side is evaluated, and if the left side of the OR is true,
the right side is skipped. Nested parens are handled properly. Parens are
indicated with the rather ugly \'left\' and \'right\' methods:

my $big_or_old_files = $files->left->size(\"+50\")->or->atime(\"+30\")->right;

The parens here correspond directly to the parens in:

find somewhere -type f \'(\' -size +50 -o -atime +30 \')\'

and are needed so that the OR and the implied ANDs have the right nesting.

Besides passing the constructed \'File::Finder\' object to
\'File::Finder::find\' directly as a \'wanted\' routine or an options hash, you
can also call \'find\' implictly, with \'in\'. \'in\' provides a list of starting
points, and returns all filenames that match the criteria.

For example, a list of all names in /tmp can be generated simply with:

my AATTnames = File::Finder->in(\"/tmp\");

For more flexibility, use \'collect\' to execute an arbitrary block in a list
context, concatenating all the results (similar to \'map\'):

my %sizes = File::Finder
->collect(sub { $File::Find::name => -s _ }, \"/tmp\");

That\'s all I can think of for now. The rest is in the detailed reference
below.
