=head1 NAME
SlackNotification - hydra-notify plugin for sending Slack notifications about
build results
=head1 DESCRIPTION
This plugin reports build statuses to various Slack channels. One can configure
which builds are reported to which channels, and whether reports should be on
state change (regressions and improvements), or for each build.
=head1 CONFIGURATION
The module is configured using the C<slack> block in Hydra's config file. There
can be multiple such blocks in the config file, each configuring different (or
even the same) set of builds and how they report to Slack channels.
The following entries are recognized in the C<slack> block:
=over 4
=item jobs
A pattern for job names. All builds whose job name matches this pattern will
emit a message to the designated Slack channel (see C<url>). The pattern will
match the whole name, thus leaving this field empty will result in no
notifications being sent. To match on all builds, use C<.*>.
=item url
The URL to a L<Slack incoming webhook|https://api.slack.com/messaging/webhooks>.
Slack administrators have to prepare one incoming webhook for each channel. This
URL should be treated as secret, as anyone knowing the URL could post a message
to the Slack workspace (or more precisely, the channel behind it).
=item force
(Optional) An I<integer> indicating whether to report on every build or only on
changes in the status. If not provided, defaults to 0, that is, sending reports
only when build status changes from success to failure, and vice-versa. Any
other value results in reporting on every build.
