NAME
    App::CSelUtils - Utilities related to Data::CSel

VERSION
    This document describes version 0.080 of App::CSelUtils (from Perl
    distribution App-CSelUtils), released on 2019-07-26.

DESCRIPTION
    This distribution contains the following utilities:

    *   ddsel

    *   parse-csel

FUNCTIONS
  ddsel
    Usage:

     ddsel(%args) -> [status, msg, payload, meta]

    Select Perl data structure elements using CSel (CSS-selector-like)
    syntax.

    Note that this operates against Perl data structure, not Perl source
    code elements (see ppisel for that). File is Perl source code that
    defines data structure, e.g.:

     {
         summary => 'This is a hash',
         # this is an array inside a hash
         array => [
             1, 2, 3,
         ],
     };

    This function is not exported.

    Arguments ('*' denotes required arguments):

    *   actions => *array[str]* (default: ["print"])

        Specify action(s) to perform on matching nodes.

    *   expr* => *str*

    *   file => *str* (default: "-")

    Returns an enveloped result (an array).

    First element (status) is an integer containing HTTP status code (200
    means OK, 4xx caller error, 5xx function error). Second element (msg) is
    a string containing error message, or 'OK' if status is 200. Third
    element (payload) is optional, the actual result. Fourth element (meta)
    is called result metadata and is optional, a hash that contains extra
    information.

    Return value: (any)

  parse_csel
    Usage:

     parse_csel(%args) -> [status, msg, payload, meta]

    Parse CSel expression.

    This function is not exported.

    Arguments ('*' denotes required arguments):

    *   expr* => *str*

    Returns an enveloped result (an array).

    First element (status) is an integer containing HTTP status code (200
    means OK, 4xx caller error, 5xx function error). Second element (msg) is
    a string containing error message, or 'OK' if status is 200. Third
    element (payload) is optional, the actual result. Fourth element (meta)
    is called result metadata and is optional, a hash that contains extra
    information.

    Return value: (any)
