=head1 NAME
Data::Unixish::splice - Perform Perl splice() on array
=head1 VERSION
This document describes version 1.574 of Data::Unixish::splice (from Perl distribution Data-Unixish), released on 2025-02-24.
=head1 SYNOPSIS
In Perl:
 use Data::Unixish qw(lduxl);
 @res = lduxl([splice => {offset=>1}], ["a","b","c"], ["d","e"],"f,g");
 # => (["a"], ["d"], [])
=head1 FUNCTIONS
=head2 splice
Usage:
 splice(%args) -> [$status_code, $reason, $payload, \%result_meta]
Perform Perl splice() on array.
This function is not exported.
Arguments ('*' denotes required arguments):
=over 4
=item * B<in> => I<array>
Input stream (e.g. array or filehandle).
=item * B<length> => I<uint>
(No description)
=item * B<list> => I<array[str]>
(No description)
=item * B<offset>* => I<uint>
(No description)
=item * B<out> => I<any>
Output stream (e.g. array or filehandle).
=back
Returns an enveloped result (an array).
First element ($status_code) is an integer containing HTTP-like status code
(200 means OK, 4xx caller error, 5xx function error). Second element
($reason) is a string containing error message, or something like "OK" if status is
200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth
element (%result_meta) is called result metadata and is optional, a hash
that contains extra information, much like how HTTP response headers provide additional metadata.
Return value:  (any)

=head1 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 L<Dist::Zilla>,
L<Dist::Zilla::PluginBundle::Author::PERLANCAR>,
L<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.

=head1 BUGS
Please report any bugs or feature requests on the bugtracker website L<https://rt.cpan.org/Public/Dist/Display.html?Name=Data-Unixish>
When submitting a bug or request, please include a test-file or a
patch to an existing test-file that illustrates the bug or desired
feature.
