DESCRIPTION

FUNCTIONS

None are exported by default, but they are exportable.

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

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.

Arguments ('*' denotes required arguments):

• bytes => bool (default: 0)

  Return the bytes counts.

• chars => bool (default: 0)

  Return the character counts.

• in => any

  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.

Return 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.
