=head1 NAME

App::GitHooks::Plugin::BlockProductionCommits - Prevent commits in a production environment.


=head1 DESCRIPTION

Committing in production means you've been developing in production. That just
sounds like a terrible idea.


=head1 VERSION

Version 1.0.2

=cut

our $VERSION = '1.0.2';


=head1 CONFIGURATION OPTIONS

This plugin supports the following options in the C<[BlockProductionCommits]>
section of your C<.githooksrc> file.

	[BlockProductionCommits]
	env_variable = my_environment
	env_safe_regex = /^development$/
	remotes_whitelist_regex = /\/my_production_tools_repository\.git$/


=head2 env_variable

The name of the environment variable to use to determine the environment.

	env_variable = my_environment


=head2 env_safe_regex

A regular expression that indicates that the environment is safe to commit when
it is matched.

	env_safe_regex = /^development$/

The example above only allow commits when C<$ENV{'my_environment'} =~ /^development$/>.


=head2 remotes_whitelist_regex

A regular expression that indicates that commits should be allowed even if the
environment is production as long as the git remote matches it.

This is particularly useful if you have many repositories on your production
machines, and one of them is used by automated tools that should still be
allowed to commit.

	remotes_whitelist_regex = /\/my_production_tools_repository\.git$/


=head1 METHODS

=head2 run_pre_commit()

Code to execute as part of the pre-commit hook.

  my $success = App::GitHooks::Plugin::BlockProductionCommits->run_pre_commit();

=cut

sub run_pre_commit
{
	my ( $class, %args ) = @_;
	my $app = delete( $args{'app'} );
	my $repository = $app->get_repository();
	my $config = $app->get_config();

	# Allow non-interactive tools to commit in production.
	my $is_interactive = defined( $config->get( 'testing', 'force_interactive' ) )
		? $config->get( 'testing', 'force_interactive' )
		: $app->get_terminal()->is_interactive();
	return $PLUGIN_RETURN_PASSED
		if !$is_interactive;

	# Check if the environment is safe to commit in.
	my $env_variable = $config->get( 'BlockProductionCommits', 'env_variable' );
	my $env_value = $ENV{ $env_variable } // '';
	my $env_regex = $config->get_regex( 'BlockProductionCommits', 'env_safe_regex' );
	return $PLUGIN_RETURN_PASSED
		if $env_value =~ $env_regex;

	# Check for whitelisted remotes, in case some specific repositories should be
	# allowed to be committed to in production.
	my $remotes_whitelist_regex = $config->get_regex( 'BlockProductionCommits', 'remotes_whitelist_regex' );
	if ( defined( $remotes_whitelist_regex ) )
	{
		my $remotes = $repository->run( 'remote', '-v' );
		return $PLUGIN_RETURN_PASSED
			if $remotes =~ /$remotes_whitelist_regex/x;
	}

	my $failure_character = $app->get_failure_character();
	print $app->wrap(
		$app->color( 'red', "$failure_character Non-dev environment detected - please commit from your dev instead.\n" ),
		"",
	);
	return $PLUGIN_RETURN_FAILED;
}
