C.S.R. BB Parser

This package was originally based on eamBBParser. Some parser internals are still based on that implementation.

Installation

Install with composer

composer require csrdelft/bb

Usage

Either use the DefaultParser or implement your own parser.

$parser = new \CsrDelft\bb\DefaultParser();

echo $parser->getHtml('[h=1]Hello World[/h]');

Custom tags

Tags must extend the \CsrDelft\bb\BbTag class. Tags must implement the parse($arguments) and getTagName() methods.

The getTagName method retuns a string or list of strings with the name(s) of this tag.

The parse method receives a map of arguments. The readContent method can be used to retrieve the contents of the tag, this content is parsed by the parser when it is received. The parser reads the input until an end tag is found. readContent has an optional parameter for tags which are forbidden to be in this tag. For instance a [sup] tag cannot contain another sup tag or a sub tag.

A tag has access to an environment, which is by default of type CsrDelft\bb\BBenv (can be overridden).

Custom tag example

class BbSuperscript extends BbTag {
	public static function getTagName() {
		return 'sup';
	}

	public function render() {
		return '<sup class="bb-tag-sup">' . $this->getContent() . '</sup>';
	}
    
    public function parse($arguments = []) {
         $this->readContent(['sub', 'sup']);
       }
}

Custom parser

A custom parser must extend Parser and contains a list of tags in the $tags field. See DefaultParser for the list of default tags.
