It took me a few minutes to get MarsEdit, Tumblr and Markdown all playing well together. Since, I didn’t come across a concise version of setting these three tools up I’m posting the configuration that worked for me. Hopefully this will work for you as well.
- Change preference (www.tumblr.com/preferences) “Edit posts using” to Markdown
- Set Default Editor Content to HTML Text (MarsEdit->Preferences->Editing
- Set Preview Text Filter and Server Text Filter to Markdown (Blog->Edit Settings …->Editing)
After making these changes, you should be able to begin posting Markdown posts to your Tumblr blog via MarsEdit. One hint: if the preview in MarsEdit is showing the markup instead of the rendering, something is probably not working. Make sure you’ve set the preview to use Markdown and make sure Tumblr is setup to use Markdown as documented above.
I haven’t used MarsEdit that extensively, but so far I really like the ability to create offline posts and just publish when I’m ready. I think this workflow will work well.
