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:
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)
