FUNCTIONS

trunc

Usage:

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

Truncate string to a certain column width.

This function can handle text containing wide characters and ANSI escape codes.

Note: to truncate by character instead of column width (note that wide characters like Chinese can have width of more than 1 column in terminal), you can turn of "mb" option even when your text contains wide characters.

This function is not exported.

Arguments ('*' denotes required arguments):

ansi => bool (default: 0)
Whether to handle ANSI escape codes.
in => array
Input stream (e.g. array or filehandle).
mb => bool (default: 0)
Whether to handle wide characters.
out => any
Output stream (e.g. array or filehandle).
width* => int

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)
