[Plugin: Markdown on Save Improved] Linebreaks aren't always ignored.

Mark’s initial plugin took a hybrid approach where it’s run through Markdown, but then paragraph tags are stripped and the remaining text is run through the wpautop filter, which inserts paragraphs for double linebreaks and br tags for single linkebreaks.

Is that what you’re describing?

This should be fixed now. Now overriding WP’s usage of wpautop.

I’ve altered the code a bit to have it check whether the wpautop filter is being used. Sometimes I want to disable this for particular themes and this makes your plugin a little less agressive when it comes to using that filter.

So if a user in their functions.php file removes the filter,

remove_filter ('the_content', 'wpautop');

then this code will honor that:

public function maybe_default_formatting($content) {
	if ( ! $this->is_markdown( get_the_ID() ) ) {
		if( has_filter( 'wpautop' ) ) {
			$content = wpautop($content);
		}
	}
	return $content;
}
