WP_CLI conditional gets repeatedly applied

[kadamwhite]

Due to the changes in PR #35 which break the wp-settings.php require out into a multi-line if statement, repeated provisioner runs add more and more surrounding if statements. I attempted to play with the file_line configuration for about an hour but couldn't find any combination of flags or changes to the match value that would prevent that.

I then tried replacing that resource with a sed call:

	exec { 'adjust chassis wp-config.php':
		# Replace
		#     require_once( ABSPATH . 'wp-settings.php' );
		# with
		#     if ( ! defined( 'WP_CLI' ) ) {
		#         require_once( ABSPATH . 'wp-settings.php' );
		#     }
		# but only once.
		command => "sed -i 's|^require_once.*ABSPATH.*wp-settings.*|if ( ! defined( 'WP_CLI' ) ) {\n\trequire_once( ABSPATH . '\''wp-settings.php'\'' );\n}|g' /vagrant/wp-config.php",
		path    => ['/bin'],
		user    => 'vagrant',
		before  => Chassis::Wp[ $config['hosts'][0] ],
	}

but that (while it works on the command line) fails in puppet with the error

==> default: Notice: /Stage[main]/Core_dev::Config/Exec[adjust chassis wp-config.php]/returns:
/bin/sed: -e expression #1, char 68: unterminated `s' command

This is annoying, but it's not the end of the world, so I'm going to cut off my troubleshooting and open this issue to revisit instead.

I do not understand why this variant does not work: I'd expect the '^' to ensure that the regex was applied to text starting that line, but intead this does not run on an unmodified wp-config.php.

	# Configure Chassis' wp-config.php per the WP Core Development guide:
	# http://docs.chassis.io/en/latest/guides/#wordpress-core-development
	file_line { 'adjust chassis wp-config.php':
		path               => '/vagrant/wp-config.php',
		append_on_no_match => false,
		multiple           => true,
		line               => "if ( ! defined( 'WP_CLI' ) ) {\n\trequire_once( ABSPATH . 'wp-settings.php' );\n}",
		match              => '^require_once.*ABSPATH.*wp-settings.php',
		# Configure wp-config.php before installing WordPress.
		before             => Chassis::Wp[ $config['hosts'][0] ],
	}
