New in the Markdown Service Tools: in-place Markdown to RTF

With help from Tobias O’Leary, the Markdown Service Tools can finally do in-place conversion from (Multi)Markdown to RTF. The primary reason for wanting this was to allow people to write Markdown directly in Mail.app, then convert it immediately before sending. Put a shortcut key on it and it’s a snap.

In order to demonstrate how exciting this is, I have made you a video.

See? Exciting.

md - Convert - MultiMarkdown to RTF is now included in the Markdown Service Tools. Please read on for some additional information and requirements.

The Service works in any Cocoa text field that handles Rich Text. If you can change your font weight, size and color in the field, you’re in the right place.

A couple of notes:

MultiMarkdown

This service requires that the MultiMarkdown binary be installed at /usr/local/bin/multimarkdown

You can do this two ways:

1. Download the installer (latest version of both the Mac and Support-Mac archives), unzip and run them.
2. If you use homebrew, just run brew install multimarkdown.

Images

Images referenced in your Markdown will disappear. Due to the way RTF handles image attachments, including them is not possible.

Styling

The default style (Swiss from Marked) is stored in ~/Library/Application Support/MarkdownServiceTools/styles/rtfstyle.txt (created the first time you run the service). This file can be edited if desired, but should remain a single line starting with “XHTML Header: “ and contain a full <style></style> declaration. Embedded fonts don’t work, and there are a lot of elements lost when converting, so it takes some experimentation.

You can boil your CSS down to a single line using any of the various compression tools, or use a web service.

How it works

The MultiMarkdown to RTF works by converting the selected Markdown using the multimarkdown binary and passing the output HTML to the OS X utility textutil. The textutil command converts the raw HTML into RTF data in a temporary file, which is then read into the RTF clipboard and pasted back to the file. That’s the secret sauce: when pbcopy -Prefer rtf is passed input on STDIN, it fails to create the clipboard RTF properly. Passing it out to a temp file and reading it back in allows it to function properly.

If you open up the workflow file in Automator, you can see the sausage factory floor.

The original contents of the clipboard are preserved and restored after the Service runs.
