FUNCTIONS

wc

Usage:

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

Print newline, word, and byte counts.

Behavior mimics that of the Unix wc utility. The order of the counts which is returned is always: newline, word, character, byte, maximum line length.

This function is not exported.

Arguments ('*' denotes required arguments):

bytes => bool (default: 0)
Return the bytes counts.
chars => bool (default: 0)
Return the character counts.
in => array
Input stream (e.g. array or filehandle).
lines => bool (default: 0)
Return the newline counts.
max_line_length => bool (default: 0)
Return the length of the longest line.
out => any
Output stream (e.g. array or filehandle).
words => bool (default: 0)
Return the word counts.

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)
