File::Find - Get a lazy list of a directory tree
use File::Find;
# recursively (and eagerly) find all files from the 'foo' directory
my @list = find(dir => 'foo');
say @list[0..3];
# the same as above, but lazily return the results
my $list = find(dir => 'foo');
say $list[0..3];
# eagerly find all Perl-related files from the current directory
my @perl-files = find(dir => '.', name => /.p [l||m] $/);
# lazily find all directories within the 'rakudo' directory
my $rakudo-dirs = find(dir => 'rakudo', type => 'dir');
# lazily find all symlinks a normal user can access under `/etc`
my $etc-symlinks = find(dir => '/etc/', type => 'symlink', keep-going => True);
File::Find allows you to get the contents of the given directory,
recursively, depth first.
The only exported function, find(), generates a lazy
list of files in given directory. Every element of the list is an
IO::Path object, described below.
find() takes one (or more) named arguments. The dir argument
is mandatory, and sets the directory find() will traverse.
There are also a few optional arguments. If more than one is passed, all of them must match for a file to be returned.
name
Specify a name of the file File::Find is ought to look for. If you
pass a string here, find() will return only the files with the given
name. When passing a regex, only the files with path matching the
pattern will be returned. Any other type of argument passed here will
just be smartmatched against the path (which is exactly what happens to
regexes passed, by the way).
exclude
Specify a regex (or any other smartmatchable type) to exclude files / directories from the search.
type
Given a type, find() will only return files being the given type.
The available types are file, dir or `symlink.
keep-going
Parameter keep-going tells find() to not stop finding files
on errors such as 'Access is denied', but rather ignore the errors
and keep going.
Perl 5's File::Find
Please note, that this module is not trying to be the verbatim port of Perl 5's File::Find module. Its interface is closer to Perl 5's File::Find::Rule, and its features are planned to be similar one day.
List assignment is eager in Perl 6, so if you assign find() result
to an array, the elements will be copied and the laziness will be
spoiled. For a proper lazy list, assign a result to a scalar value
(see SYNOPSIS).
