How to render only inlines?

[ducaale]

is there a method for inline rendering ?
example:

$converter = new CommonMarkConverter();
$converter->convertToHtml('hello');

to produce hello instead of <p>hello</p>

[colinodell]

You could create a custom renderer for Paragraph blocks which only renders its inlines and not the <p> tags:

class InlineOnlyRenderer implements BlockRendererInterface
{
    public function render(AbstractBlock $block, ElementRendererInterface $htmlRenderer, $inTightList = false)
    {
        return $htmlRenderer->renderInlines($block->children());
    }
}

To use it:

// Create the standard environment with all the default parsers, renderers, etc.
$environment = Environment::createCommonMarkEnvironment();
// Override the default Paragraph renderer with the one we just created
$environment->addBlockRenderer(Paragraph::class, new InlineOnlyRenderer());

// Instantiate the converter with the custom Environment we just configured
$converter = new CommonMarkConverter([], $environment);

// Convert to HTML
echo $converter->convertToHtml('**Hello World!**');

I hope that helps!

We now have an Inlines-Only Extension which solves this use case.

@colinodell Thanks for the extension.

Is there any way to remove or make CommonMark\Node\Inline\Image::class optional.

[colinodell]

You have three options here:

1. Add an event listener that iterates the AST and removes Image::class instances from the Document before rendering happens
2. Add an additional custom renderer for Image::class with a high priority and have it always return empty strings
3. Create your own copy of InlinesOnlyException without the ImageRenderer

All of them will have the same result where the parser will still locate images in the Markdown but prevent them from showing up in the output.

Another option to me is to just use preg_replace to the converted html. Thanks!
