FUNCTIONS

bool

Usage:

 bool(%args) -> [status, msg, result, meta]

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: "perl")

  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.

  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

  • 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) 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 (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.
