=head1 FUNCTIONS


=head2 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):

=over 4

=item * B<cmndline_pat> => I<re_from_str>

Filter processes using regex against their cmndline.

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

=item * B<exec_pat> => I<re_from_str>

Filter processes using regex against their exec.

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

=item * B<fname_pat> => I<re_from_str>

Filter processes using regex against their fname.

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

=item * B<pid_pat> => I<re_from_str>

Filter processes using regex against their pid.

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

=item * B<quiet> => I<true>

(No description)

=item * B<users> => I<array[unix::uid::exists]>

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


=back

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)



=head2 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 I<all> of its processes are in 'stop' state.

This function is not exported.

Brave is defined as running if there are some Brave processes that are I<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 C<ps_brave>.

=head2 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 C<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 C<periods> option.

=head1 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 L<Dist::Zilla>,
L<Dist::Zilla::PluginBundle::Author::PERLANCAR>,
L<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.
