Question: Is there a way to remove markdown syntax ?

[Bacteries]

Hi,
I use Commonmark and it works well but I have a case where I need to display my text on a non HTML output.
Is there a way to take the markdow text and return the text without the Markdown ? (and keep list "-") ?

I know something like this could works, but I was searching for the proper way (extension maybe ?) to do this, and if one already exists.

$string = str_replace(['<li>'], ['- '], $htmlFromMarkdown);
return strip_tags($string);

Thanks.

You could implement custom block renderers and inline renderers. Although they are intended to output HTML there's nothing stopping you from returning any text strings that you want :)

You could then group those renderers into an extension or add them manually to the Environment - both will accomplish the same thing. Just make sure you set a higher priority so that your renderers are used instead of the core ones.

Hi @colinodell : I make my own renderers and it works fine ! Thanks.

@Bacteries Hello! Could you share the code how you achieve that. If you could. Thank you!

@Bacteries Hello! Could you share the code how you achieve that. If you could. Thank you!

Here my code,
Some extension are mine.

class MarkdownToTextExtension implements ExtensionInterface
{
    public function register(ConfigurableEnvironmentInterface $environment)
    {
        $simpleInlineRenderer = new SimpleInlineRenderer();

        $environment
            ->addExtension(new MarkExtension())
            ->addExtension(new StrikethroughExtension())
            ->addExtension(new UnderlineExtension())
            ->addBlockParser(new BlockParser\ATXHeadingParser(), 60)
            ->addBlockParser(new BlockParser\HtmlBlockParser(), 40)
            ->addBlockParser(new BlockParser\SetExtHeadingParser(), 30)
            ->addBlockParser(new BlockParser\ThematicBreakParser(), 20)
            ->addBlockParser(new BlockParser\ListParser(), 10)
            ->addBlockParser(new BlockParser\LazyParagraphParser(), -200)
            ->addInlineParser(new InlineParser\NewlineParser(), 200)
            ->addInlineParser(new InlineParser\EscapableParser(), 80)
            ->addInlineParser(new InlineParser\EntityParser(), 70)
            ->addInlineParser(new InlineParser\AutolinkParser(), 50)
            ->addInlineParser(new InlineParser\CloseBracketParser(), 30)
            ->addInlineParser(new InlineParser\OpenBracketParser(), 20)

            ->addBlockRenderer(BlockElement\Document::class, new DocumentRenderer(), 0)
            ->addBlockRenderer(BlockElement\Heading::class, new HeadingRenderer(), 0)
            ->addBlockRenderer(BlockElement\HtmlBlock::class, new HtmlBlockRenderer(), 0)
            ->addBlockRenderer(BlockElement\ListBlock::class, new ListBlockRenderer(), 0)
            ->addBlockRenderer(BlockElement\ListItem::class, new ListItemRenderer(), 0)
            ->addBlockRenderer(BlockElement\Paragraph::class, new ParagraphRenderer(), 0)
            ->addBlockRenderer(BlockElement\ThematicBreak::class, new ThematicBreakRenderer(), 0)
            ->addBlockRenderer(BreakPage::class, new BreakPageRenderer())

            ->addInlineRenderer(InlineElement\Emphasis::class, $simpleInlineRenderer, 0)
            ->addInlineRenderer(InlineElement\HtmlInline::class, new HtmlInlineRenderer(), 0)
            ->addInlineRenderer(InlineElement\Link::class, $simpleInlineRenderer, 0)
            ->addInlineRenderer(InlineElement\Newline::class, new NewlineRenderer(), 0)
            ->addInlineRenderer(InlineElement\Strong::class, $simpleInlineRenderer, 0)
            ->addInlineRenderer(InlineElement\Text::class, new TextRenderer(), 0)
            ->addInlineRenderer(Mark::class, $simpleInlineRenderer, 10)
            ->addInlineRenderer(Strikethrough::class, $simpleInlineRenderer, 10)
            ->addInlineRenderer(Underline::class, $simpleInlineRenderer, 10)
        ;

        if ($environment->getConfig('use_asterisk', true)) {
            $environment->addDelimiterProcessor(new EmphasisDelimiterProcessor('*'));
        }

        if ($environment->getConfig('use_underscore', true)) {
            $environment->addDelimiterProcessor(new EmphasisDelimiterProcessor('_'));
        }
    }
}

For some Renderer :

final class Mark extends AbstractInline
{
    public function isContainer(): bool
    {
        return true;
    }
}
