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):

  • 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.

  • quiet => true

    (No description)

  • 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):

  • 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.

  • 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.

  • quiet => true

    (No description)

  • users => array[unix::uid::exists]

    Kill browser processes that belong to certain user(s) only.

Second element ($reason) is a string containing error message, or something like "OK" if status is 200.

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):

  • cmndline_pat => re_from_str

    Filter processes using regex against their cmndline.

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).

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):

  • 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.

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.

BUGS

Please report any bugs or feature requests on the bugtracker website https://rt.cpan.org/Public/Dist/Display.html?Name=App-BraveUtils

When submitting a bug or request, please include a test-file or a patch to an existing test-file that illustrates the bug or desired feature.
