I've run into a unique situation where Marked is not previewing correctly. Using the following MMD text in Byword:

Title: TEMPX - Test post for Marked Preview

9:42am - Email from

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer enim lectus, dictum ut ultricies in, placerat non orci. Proin eu lorem vehicula erat sollicitudin suscipit vel et nulla. Mauris ut risus urna, id consectetur arcu. Nam ac tempus eros. Nulla velit arcu, lacinia a cursus vel, iaculis non felis. Phasellus hendrerit rhoncus mauris at elementum. Proin sollicitudin dolor vel purus sodales elementum. Pellentesque sed urna nisi. Etiam accumsan ligula augue.

Marked is only showing the 'Lorem ipsum...' paragraph. If I append a character in front of the first line, other than a space, then the preview works fine. I verified that text above previews as expected in Byword's preview and MMD Composer's preview.

Included are screen shots showing Byword and Marked previews.

   It's not the number, it's the colon. MultiMarkdown looks for MMD-style metadata in the first lines before the first break. Your is interpreted as such. If you put a blank line in above it, it will solve the issue.

   Actually, wait. Is the Title: line part of the document as well?

   Yes, the Title line is the first line in the MMD document.

   I can get the same text to preview in Byword and MMD Composer. I've attached the actual MMD doc to discussion.

   Yes, the 'Title' line is the first line in the document. I attached a copy of the MMD doc to the discussion thread.

   Sorry, reading these over email and didn't see the attachment. It looks like in your first example that the feature that figures out where the last change to the text was may actually be breaking the tag in the first line. Could you try opening the same document and adding a line of text at the end, then saving and seeing how the preview updates?

   Added a line at the end of the MMD doc, clicked Save, and the Marked showed the added text but didn't show the "9:42am - Email from" line.

   Ok, figured out what's going on. Marked strips the MMD header data (Title:) before rendering the preview to prevent MultiMarkdown from generating a complete HTML document. This is leaving the date line, though, which MMD is then recognizing as metadata because the title line and line break have already been stripped. This issue is solved for the next version.

   I realize it's inconvenient and I apologize, but could you --- for the time being --- reformat the documents such that the first line after the existing metadata did not contain a colon in the first 20 characters?

   No problem. I'll either do that or grab the HTML output from Byword.
