SYNOPSIS

use Data::Unixish qw(lduxl);
my @res = lduxl([bool => {style=>"check_cross"}], [0, "one", 2, ""])

FUNCTIONS

bool

Usage:

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

Format boolean.

This function is not exported.

Arguments ('*' denotes required arguments):

  • false_char => str

    Instead of style, you can also specify character for true value.

  • in => array

    Input stream (e.g. array or filehandle).

  • notion => str (default: "n1+en_id")

    What notion to use to determine true/false.

    perl uses Perl notion.

    n1 (for lack of better name) is just like Perl notion, but empty array and empty hash is considered false.

    n1+en_id is like n1 but also handle 'Yes', 'No', 'true', 'false', etc (English) and 'ya', 'tidak', etc (Indonesian).

    TODO: add Ruby, Python, PHP, JavaScript, etc notion.

  • out => any

    Output stream (e.g. array or filehandle).

  • style => str (default: "one_zero")

    Available styles:

    • Y_N: N Y

    • check (uses Unicode): ✓

    • check_cross (uses Unicode): ✕ ✓

    • dot (uses Unicode): ●

    • dot_cross (uses Unicode): ✘ ●

    • heavy_check_cross (uses Unicode): ✘ ✔

    • one_zero: 0 1

    • t_f: f t

    • true_false: false true

    • v_X: X v

    • y_n: n y

    • yes_no: no yes

  • true_char => str

    Instead of style, you can also specify character for true value.

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.
