NAME
    App::hr - Print horizontal bar on the terminal

VERSION
    This document describes version 0.261 of App::hr (from Perl distribution
    App-hr), released on 2019-07-30.

SYNOPSIS
     use App::hr qw(hr hr_r);
     hr;

    Sample output:

     =============================================================================

    Set pattern:

     hr('x----');

    Sample output:

     x----x----x----x----x----x----x----x----x----x----x----x----x----x----x----x-

    Use random color and random pattern:

     hr_r;

    You can also use the provided CLI hr.

NO_COLOR
  COLOR
FUNCTIONS
  hr([ $pattern [, $color ] ]) => optional STR
    Print (under void context) or return (under scalar/array context) a
    horizontal ruler with the width of the terminal.

    Terminal width is determined using Term::Size.

    $pattern is optional, can be multicharacter, but cannot be empty string.
    The defautl is "=".

    Under Windows, will shave one character at the end because the terminal
    cursor will move a line down when printing at the last column.

    If $color is set (to a color supported by Term::ANSIColor) *and* colored
    output is enabled, output will be colored. Colored output is enabled if:
    1) no "NO_COLOR" environment variable is defined; 2) "COLOR" is
    undefined or true, or program is run interactively.

  hr_r => optional STR
    Like "hr", but will set random pattern and random color.

  hr_app
    Usage:

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

    Print horizontal bar on the terminal.

    hr can be useful as a marker/separator, especially if you use other
    commands that might produce a lot of output, and you need to scroll back
    lots of pages to see previous output. Example:

     % hr; command-that-produces-lots-of-output
     ============================================================================
     Command output
     ...
     ...
     ...
 
     % hr -r; some-command; hr -r; another-command

    Usage:

     % hr
     ============================================================================
 
     % hr -c red  ;# will output the same bar, but in red
 
     % hr --random-color  ;# will output the same bar, but in random color
 
     % hr x----
     x----x----x----x----x----x----x----x----x----x----x----x----x----x----x----x
 
     % hr -- -x-  ;# specify a pattern that starts with a dash
     % hr -p -x-  ;# ditto
 
     % hr --random-pattern
     vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
 
     % hr --random-pattern
     *---*---*---*---*---*---*---*---*---*---*---*---*---*---*---*---*---*---*---
 
     % hr -r  ;# shortcut for --random-pattern --random-color
 
     % hr --help

    If you use Perl, you can also use the "hr" function in App::hr module.

    This function is not exported.

    Arguments ('*' denotes required arguments):

    *   color => *str*

        Specify a color (see Term::ANSIColor).

    *   height => *int* (default: 1)

        Specify height (number of rows).

    *   pattern => *str*

        Specify a pattern.

    *   random_color => *bool*

    *   random_pattern => *bool*

    *   space_after => *int* (default: 0)

        Number of empty rows after drawing the bar.

    *   space_before => *int* (default: 0)

        Number of empty rows before drawing the bar.

    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)
