SYNOPSIS


            

              
              
use Data::Unixish::Apply;
Data::Unixish::Apply::apply(

DESCRIPTION

FUNCTIONS

apply

Usage:


            

              
              
apply(%args) -> [$status_code, $reason, $payload, \%result_meta]

Apply one or more dux functions.

This function is not exported.

Arguments ('*' denotes required arguments):

  • functions* => str|array[str|array]

    Function(s) to apply.

    A list of functions to apply. Each element is either a string (function name), or a 2-element array (function names + arguments hashref). If you do not want to specify arguments to a function, you can use a string.

    Example:

    
            
    
              
              
    [
        'sort', # no arguments (all default)
        'date', # no arguments (all default)
        ['head', {items=>5}], # specify arguments
    ]

  • in* => any

    (No description)

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)

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.
