NAME App::BraveUtils - Utilities related to Brave browser VERSION This document describes version 0.001 of App::BraveUtils (from Perl distribution App-BraveUtils), released on 2022-10-07. SYNOPSIS DESCRIPTION This distribution includes several utilities related to Brave browser: * brave-has-processes * brave-is-paused * brave-is-running * kill-brave * pause-and-unpause-brave * pause-brave * ps-brave * restart-brave * start-brave * terminate-brave * unpause-brave FUNCTIONS brave_has_processes Usage: brave_has_processes(%args) -> [$status_code, $reason, $payload, \%result_meta] Check whether Brave has processes. This function is not exported. Arguments ('*' denotes required arguments): * quiet => *true* * users => *array[unix::uid::exists]* Kill browser processes that belong to certain user(s) only. Returns an enveloped result (an array). First element ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata. Return value: (any) brave_is_paused Usage: brave_is_paused(%args) -> [$status_code, $reason, $payload, \%result_meta] Check whether Brave is paused. Brave is defined as paused if *all* of its processes are in 'stop' state. This function is not exported. Arguments ('*' denotes required arguments): * quiet => *true* * users => *array[unix::uid::exists]* Kill browser processes that belong to certain user(s) only. Returns an enveloped result (an array). First element ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata. Return value: (any) brave_is_running Usage: brave_is_running(%args) -> [$status_code, $reason, $payload, \%result_meta] Check whether Brave is running. Brave is defined as running if there are some Brave processes that are *not* in 'stop' state. In other words, if Brave has been started but is currently paused, we do not say that it's running. If you want to check if Brave process exists, you can use "ps_brave". This function is not exported. Arguments ('*' denotes required arguments): * quiet => *true* * users => *array[unix::uid::exists]* Kill browser processes that belong to certain user(s) only. Returns an enveloped result (an array). First element ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata. Return value: (any) pause_and_unpause_brave Usage: pause_and_unpause_brave(%args) -> [$status_code, $reason, $payload, \%result_meta] Pause and unpause Brave alternately. A modern browser now runs complex web pages and applications. Despite browser's power management feature, these pages/tabs on the browser often still eat considerable CPU cycles even though they only run in the background. Pausing (kill -STOP) the browser processes is a simple and effective way to stop CPU eating on Unix and prolong your laptop battery life. It can be performed whenever you are not using your browser for a little while, e.g. when you are typing on an editor or watching a movie. When you want to use your browser again, simply unpause (kill -CONT) it. The "pause-and-unpause" action pause and unpause browser in an alternate fashion, by default every 5 minutes and 30 seconds. This is a compromise to save CPU time most of the time but then give time for web applications in the browser to catch up during the unpause window (e.g. for WhatsApp Web to display new messages and sound notification.) It can be used when you are not browsing but still want to be notified by web applications from time to time. If you run this routine, it will start pausing and unpausing browser. When you want to use the browser, press Ctrl-C to interrupt the routine. Then after you are done with the browser and want to pause-and-unpause again, you can re-run this routine. You can customize the periods via the "periods" option. This function is not exported. Arguments ('*' denotes required arguments): * periods => *array[duration]* Pause and unpause times, in seconds. For example, to pause for 5 minutes, then unpause 10 seconds, then pause for 2 minutes, then unpause for 30 seconds (then repeat the pattern), you can use: 300,10,120,30 * users => *array[unix::uid::exists]* Kill browser processes that belong to certain user(s) only. Returns an enveloped result (an array). First element ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata. Return value: (any) pause_brave Usage: pause_brave(%args) -> [$status_code, $reason, $payload, \%result_meta] Pause (kill -STOP) Brave. A modern browser now runs complex web pages and applications.

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.
