hr - Print horizontal bar on the terminal
This document describes version 0.268 of main::_DataPacker (from Perl distribution App-hr), released on 2022-09-03.
hr [--blink|-B|--no-blink|--noblink] [--color=str|-c=str] [--height=int|-H=int] [--random-color] [--random-pattern|-r] [--space-after=int|-a=int] [--space-before=int|-b=int] -- [pattern]
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 -Br ;# a BLINKING random pattern, random color bar % hr --help
If you use Perl, you can also use the hr function in App::hr module.

The script comes with a companion shell completer script (_hr) for this script.
To activate bash completion for this script, put:
complete -C _hr hr
in your bash startup (e.g. ~/.bashrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.
It is recommended, however, that you install modules using cpanm-shcompgen which can activate shell completion for scripts immediately.
To activate tcsh completion for this script, put:
complete hr 'p/*/`hr`/'
in your tcsh startup (e.g. ~/.tcshrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.
It is also recommended to install shcompgen (see above).
For fish and zsh, install shcompgen as described above.

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.
Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:
% prove -l
If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
