NAME

Data::Sah::Filter::perl::Array::dupestr - Return the elements of array that appear more than once

VERSION

This document describes version 0.002 of Data::Sah::Filter::perl::Array::dupestr (from Perl distribution Data-Sah-FilterBundle-Array), released on 2024-02-06.

SYNOPSIS

Using in Sah schema's prefilters (or postfilters) clause

["str","prefilters",[["Array::dupestr"]]]

Using with Data::Sah:

use Data::Sah qw(gen_validator);

my $schema = ["str","prefilters",[["Array::dupestr"]]];
my $validator = gen_validator($schema);
if ($validator->($some_data)) { print 'Valid!' }

Using with Data::Sah:Filter directly:

use Data::Sah::Filter qw(gen_filter);

my $filter = gen_filter([["Array::dupestr"]]);
my $filtered_value = $filter->($some_data);

Sample data and filtering results

[] # valid, unchanged
["a","b"] # valid, becomes []
["a","b","a","a","c","b"] # valid, becomes ["a","a","b"]
["a","b","a","a","c","b"] # filtered with args {uniq=>1}, valid, becomes ["a","b"]

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

% prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
