MermaidPhp

First, make yourself familiar with the brilliant Mermaid project.

Basically, MermaidPhp provides you a nice and clean interface to generate compatible with Mermaid code.

Now (if you want to give it a try), lets review the installation process.

Installation

In order to install MermaidPhp, you need Composer.

Run the following command in your project root directory:

composer require bound1ess/mermaid-php:~1.0

Ok, now include vendor/autoload.php file in your project (if you have not done this yet) and you are all set to go!

Example of usage

This PHP code:

use Bound1ess\MermaidPhp\Graph,
	Bound1ess\MermaidPhp\Printer,
	Bound1ess\MermaidPhp\Node,
	Bound1ess\MermaidPhp\Link;

$graph = new Graph('from left to right');

$graph->addNodes(
	$a = new Node('A', ['Hard edge']),
	$b = new Node('B', ['Round edge', Node::ROUND_EDGE]),
	$c = new Node('C', ['Decision', Node::RHOMBUS]),
	$d = new Node('D', ['Result one']),
	$e = new Node('E', ['Result two'])
);

$graph->addLinks(
	new Link($a, $b, 'Link text'),
	new Link($b, $c),
	new Link($c, $d, 'One'),
	new Link($c, $e, 'Two')
);

$code = (new Printer)->printGraph($graph);

Will produce something like this:

If you want to see this example in your browser, do the following:

• Execute vendor/bound1ess/php-mermaid/examples/create file, it will produce example.html file in your project root directory.
• Now set up a PHP development server by running this command: php -S localhost:8000.
• View the example.html file in your browser by visiting localhost:8000/example.html.

API

• Bound1ess\MermaidPhp\Printer

  • __construct($testMode = false)
    • $testMode: when set to true, Printer will produce code that is invalid, but much easier to test.
  • printGraph(Graph $graph, $wrapInDiv = false)
    • $graph: an instance of Bound1ess\MermaidPhp\Graph is expected.
    • $wrapInDiv: when set to true, the code produced will be wrapped in a <div> element with the class mermaid.
    • This method will return a string.

• Bound1ess\MermaidPhp\Graph

  • __construct($direction = null)
    • $direction: if not null, setDirection method will be called.
  • setDirection($direction)
    • $direction: valid values are Node::TOP_BOTTOM, Node::BOTTOM_TOP, Node::LEFT_RIGHT, Node::RIGHT_LEFT, from top to bottom, from bottom to top, from left to right, from right to left.
    • This method will return nothing (void).
    • This method can throw an instance of Bound1ess\MermaidPhp\Exceptions\InvalidDirectionException.
  • addNode(Node $node)
    • $node: an instance of Bound1ess\MermaidPhp\Node is expected.
    • This method will return nothing (void).
  • addNodes(Node $node, ...)
  • addLink(Link $link)
    • $link: an instance of Bound1ess\MermaidPhp\Link is expected.
    • This method will return nothing (void).
  • addLinks(Link $link, ...)
  • addClass(NodeClass $class)
    • $class: an instance of Bound1ess\MermaidPhp\NodeClass.
    • This method will return nothing (void).
  • addClasses
    • dynamic: as many Bound1ess\MermaidPhp\NodeClass instances as you need.
    • This method will return nothing (void).

• Bound1ess\MermaidPhp\Node

  • __construct($id, array $settings = null)
    • $id: the node id (should be a string).
    • $settings: if not null, setText method will be called.
  • setText($text, $style = null)
    • $text: the node text (should be a string).
    • $style: valid values are Node::ROUND_EDGE, Node::SQUARE_EDGE, Node::CIRCLE, Node::RHOMBUS, Node::ASYMETRIC_SHAPE. If null is passed, Node::SQUARE_EDGE will be used.
    • This method can throw an instance of Bound1ess\MermaidPhp\Exceptions\InvalidStyleException.
    • This method will return nothing (void).
  • attachClass($name)
    • $name: the class name as a string.
    • This method will return nothing (void).
  • attachClasses
    • dynamic: as many strings as you need.
    • This method will return nothing (void).

• Bound1ess\MermaidPhp\Link

  • __construct(Node $node, Node $anotherNode, $text = null, $isOpen = false)
    • $node: an instance of Bound1ess\MermaidPhp\Node is expected.
    • $anotherNode: an instance of Bound1ess\MermaidPhp\Node is expected.
    • $text: the text on link (should be a string or null).
    • $isOpen: whether the link should be open or with arrow head (should be a boolean, the default value is false).
  • setText($text)
    • $text: the text on link (should be a string).
    • This method will return nothing (void).
  • isOpen($newValue = null)
    • $newValue: if null is passed, this method will return the current value, otherwise new value will be set (should be a boolean value).
    • This method will return a boolean value or nothing (void).

• Bound1ess\MermaidPhp\NodeClass

  • __construct($name)
    • $name: the class name as a string.
  • add($property, $value)
    • $property: the property name as a string.
    • $value: the property value as a string.
    • This method will return the class instance itself.
