NAME App::VivaldiUtils - Utilities related to the Vivaldi browser VERSION This document describes version 0.005 of App::VivaldiUtils (from Perl distribution App-VivaldiUtils), released on 2020-04-19. SYNOPSIS DESCRIPTION This distribution includes several utilities related to the Vivaldi browser: * kill-vivaldi * pause-vivaldi * ps-vivaldi * terminate-vivaldi * unpause-vivaldi * vivaldi-is-paused * vivaldi-is-running FUNCTIONS pause_vivaldi Usage: pause_vivaldi(%args) -> [status, msg, payload, meta] Pause (kill -STOP) Vivaldi. 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. Stopping (kill -STOP) the browser processes is a simple and effective way to stop CPU eating on Unix. It can be performed whenever you are not using your browsers 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 it. This function is not exported. Arguments ('*' denotes required arguments): * users => *array[unix::local_uid]* Kill browser processes that belong to certain user(s) only. 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) ps_vivaldi Usage: ps_vivaldi(%args) -> [status, msg, payload, meta] List Vivaldi processes. This function is not exported. Arguments ('*' denotes required arguments): * users => *array[unix::local_uid]* Kill browser processes that belong to certain user(s) only. 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) terminate_vivaldi Usage: terminate_vivaldi(%args) -> [status, msg, payload, meta] Terminate (kill -KILL) Vivaldi. This function is not exported. Arguments ('*' denotes required arguments): * users => *array[unix::local_uid]* Kill browser processes that belong to certain user(s) only. 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) unpause_vivaldi Usage: unpause_vivaldi(%args) -> [status, msg, payload, meta] Unpause (resume, continue, kill -CONT) Vivaldi. This function is not exported. Arguments ('*' denotes required arguments): * users => *array[unix::local_uid]* Kill browser processes that belong to certain user(s) only. 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) vivaldi_is_paused Usage: vivaldi_is_paused(%args) -> [status, msg, payload, meta] Check whether Vivaldi is paused. Vivaldi 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::local_uid]* Kill browser processes that belong to certain user(s) only. 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) vivaldi_is_running Usage: vivaldi_is_running(%args) -> [status, msg, payload, meta] Check whether Vivaldi is running. Vivaldi is defined as running if there are some Vivaldi processes that are *not* in 'stop' state. In other words, if Vivaldi has been started but is currently paused, we do not say that it's running. If you want to check if Vivaldi process exists, you can use "ps_vivaldi". This function is not exported. Arguments ('*' denotes required arguments): * quiet => *true* * users => *array[unix::local_uid]* Kill browser processes that belong to certain user(s) only. 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) HOMEPAGE Please visit the project's homepage at .
