App::VivaldiUtils - Utilities related to the Vivaldi browser

VERSION

This document describes version 0.011 of App::VivaldiUtils (from Perl distribution App-VivaldiUtils), released on 2023-10-28.

SYNOPSIS

DESCRIPTION

This distribution includes several utilities related to the Vivaldi browser:

1. kill-vivaldi
2. list-vivaldi-profiles
3. pause-vivaldi
4. ps-vivaldi
5. restart-vivaldi
6. start-vivaldi
7. terminate-vivaldi
8. unpause-vivaldi
9. vivaldi-has-processes
10. vivaldi-is-paused
11. vivaldi-is-running

FUNCTIONS

pause_vivaldi

Usage:

pause_vivaldi(%args) -> [$status_code, $reason, $payload, \%result_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. 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.

This function is not exported.

Arguments ('*' denotes required arguments):

  • cmndline_pat => re_from_str

    Filter processes using regex against their cmndline.

    If one of the *-pat options are specified, then instead of the default heuristic rules to find the browser processes, these *-pat options are solely used to determine which processes are the browser processes.

  • exec_pat => re_from_str

    Filter processes using regex against their exec.

    If one of the *-pat options are specified, then instead of the default heuristic rules to find the browser processes, these *-pat options are solely used to determine which processes are the browser processes.

  • fname_pat => re_from_str

    Filter processes using regex against their fname.

    If one of the *-pat options are specified, then instead of the default heuristic rules to find the browser processes, these *-pat options are solely used to determine which processes are the browser processes.

  • pid_pat => re_from_str

    Filter processes using regex against their pid.

    If one of the *-pat options are specified, then instead of the default heuristic rules to find the browser processes, these *-pat options are solely used to determine which processes are the browser processes.

  • 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)

ps_vivaldi

Usage:

ps_vivaldi(%args) -> [$status_code, $reason, $payload, \%result_meta]

List Vivaldi processes.

CONTRIBUTING

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.
