Table renderer

Allows to render tree structures as tables.

HTML example

Trees

Elements

There are 3 main elements of every tree:

Atomic values

They are indivisible.

TextValue

It simply holds some text which will be rendered inside some cell.

use lukaszmakuch\TableRenderer\TextValue;

$flowers = new TextValue("roses");

Containers

They hold other elements.

HorizontalContainer

Its elements are on top of each other.

use lukaszmakuch\TableRenderer\HorizontalContainer;
use lukaszmakuch\TableRenderer\TextValue;

$column = (new HorizontalContainer())
    ->add(new TextValue("top"))
    ->add(new TextValue("bottom"));

HorizontalContainer

Its elements are next to each other.

use lukaszmakuch\TableRenderer\VerticalContainer;
use lukaszmakuch\TableRenderer\TextValue;

$row = (new VerticalContainer())
    ->add(new TextValue("left"))
    ->add(new TextValue("right"));

Building trees

It's possible to build a composite of any complexity.

use lukaszmakuch\TableRenderer\HorizontalContainer;
use lukaszmakuch\TableRenderer\VerticalContainer;
use lukaszmakuch\TableRenderer\TextValue;

$table = (new HorizontalContainer())
    ->add((new VerticalContainer())
        ->add(new TextValue("top left"))
        ->add(new TextValue("top middle"))
        ->add(new TextValue("top right"))
    )
    ->add((new VerticalContainer())
        ->add(new TextValue("bottom left"))
        ->add(new TextValue("bottom right"))
    );

Renderers

Allows to render tables based on tree structures.

HTMLRenderer

Renders HTML code.

Getting the renderer

use lukaszmakuch\TableRenderer\HTMLRenderer\HTMLRendererBuilder;

$builder = new HTMLRendererBuilder();
$htmlRenderer = $builder->buildRenderer();

Basic usage

use lukaszmakuch\TableRenderer\VerticalContainer;
use lukaszmakuch\TableRenderer\TextValue;
use lukaszmakuch\TableRenderer\HTMLRenderer\HTMLRenderer;

$tree = (new VerticalContainer())
    ->add(new TextValue("left"))
    ->add(new TextValue("right"));

/* @var $renderer HTMLRenderer */
echo $renderer->renderHTMLBasedOn($tree);

Adding HTML attributes

It's possible to assign HTML attributes to atomic values as well as to a whole table. ObjectAttributeContainer is used to achieve that.

Building renderer with support of additional attributes

First, you need to build the renderer with some attribute container.

use lukaszmakuch\TableRenderer\HTMLRenderer\HTMLRendererBuilder;
use lukaszmakuch\ObjectAttributeContainer\Impl\ObjectAttributeContainerImpl;

//source of attributes
$attrs = new ObjectAttributeContainerImpl();

//building with the attribute container
$builder = new HTMLRendererBuilder();
$builder->setAttributeContainer($attrs);

$htmlRenderer = $builder->buildRenderer();

Adding attributes to a tree.

use lukaszmakuch\ObjectAttributeContainer\ObjectAttributeContainer;
use lukaszmakuch\TableRenderer\VerticalContainer;
use lukaszmakuch\TableRenderer\TextValue;
lukaszmakuch\TableRenderer\HTMLRenderer\HTMLRenderer;

/* @var $attrs ObjectAttributeContainer */

//table with border 1
$tree = $attrs->addObjAttrs(

    (new VerticalContainer())

        //cell with no extra style
        ->add(new TextValue("left"))

        //cell with red text
        ->add($attrs->addObjAttrs(
            new TextValue("right"),
            ["attrs" => ["style" => "color: #f00"]]
        )),

    ["attrs" => ["border" => 1]]
);

/* @var $renderer HTMLRenderer */
echo $renderer->renderHTMLBasedOn($tree);

Support of custom atomic values

This renderer supports custom atomic values. A custom value should extend AtomicCellValue and be supported by an instance of AtomicValueRenderer. Then you can register a new atomic value renderer like that:

use lukaszmakuch\TableRenderer\HTMLRenderer\HTMLRendererBuilder;

/* @var @builder HTMLRendererBuilder */
$builder->addAtomicValueRenderer(
    NewAtomicType::class,
    new NewAtomicTypeRenderer()
);

ScalarRenderer

It renders models of tables as scalar values or arrays of scalar values (or other arrays).

Getting the renderer

use lukaszmakuch\TableRenderer\ScalarRenderer\ScalarRendererBuilder;

$renderer = (new ScalarRendererBuilder())->build();

Basic usage

use lukaszmakuch\TableRenderer\VerticalContainer;
use lukaszmakuch\TableRenderer\TextValue;
use lukaszmakuch\TableRenderer\ScalarRenderer\ScalarRenderer;

$tree = (new VerticalContainer())
    ->add(new TextValue("first"))
    ->add(new TextValue("second"));

/* @var $renderer ScalarRenderer */
var_dump($renderer->getScalarRepresentationOf($tree));
//[
//    'type' => 'vertical-container',
//    'value' => [
//        ['type' => 'text', 'value' => 'first'],
//        ['type' => 'text', 'value' => 'second']
//     ]
//]

Support of custom elements

This renderer supports custom elements. A custom element should extend AtomicCellValue and be supported by an instance of ScalarRenderer. Then you can register a new element renderer like that:

use lukaszmakuch\TableRenderer\ScalarRenderer\ScalarRendererBuilder;

/* @var @builder ScalarRendererBuilder */
$builder->addRenderer(
    NewAtomicType::class,
    new NewAtomicTypeRenderer()
);
