VERSION

This document describes version 0.081 of App::CSelUtils (from Perl distribution App-CSelUtils), released on 2019-07-27.

DESCRIPTION

This distribution contains the following utilities:

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)
