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.
hr_app(%args) -> [status, msg, result, 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

% 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
