, _(*1)

Usage

<?php
require_once 'vendor/autoload.php';

use AydinHassan\CliMdRenderer\CliRendererFactory;
use League\CommonMark\Environment\Environment;
use League\CommonMark\Parser\MarkdownParser;

$parser       = new MarkdownParser((new Environment())->addExtension(new CommonMarkCoreExtension()));
$parser       = new DocParser(Environment::createCommonMarkEnvironment());
$cliRenderer  = (new CliRendererFactory)->__invoke();
$ast          = $parser->parse(file_get_contents('path/to/file.md'));

echo $cliRenderer->renderBlock($ast);

Syntax Highlighting

FencedCode can be syntax highlighted. By default only PHP source code is Syntax Highlighted using: kadet/keylighter If you want to add syntax highlighting for other languages you should create a class which implements \AydinHassan\CliMdRenderer\SyntaxHighlighterInterface, _(*2)

It accepts code as a string and should return highlighted code as a string. You register your highlighter like so, _(*3)

<?php

use AydinHassan\CliMdRenderer\Renderer\FencedCodeRenderer;

$codeRenderer = new FencedCodeRenderer;
$codeRenderer->addSyntaxHighlighter('js', new JsSyntaxHighlighter);

If you need to do this you cannot use the factory so construction will look something like:, _(*4)

<?php 
require_once 'vendor/autoload.php';

use AydinHassan\CliMdRenderer\Highlighter\PhpHighlighter;
use AydinHassan\CliMdRenderer\InlineRenderer\LinkRenderer;
use AydinHassan\CliMdRenderer\Renderer\DocumentRenderer;
