I noticed recently that Spotlight on Yosemite was no longer indexing my Markdown files. Since all my notes are in Markdown format, and Spotlight is how I find my notes, this was a big problem. Reinstalling my current set of Markdown editors did not help.
This did. Huge thanks to Gereon Sommer for the idea in Mac OS X Spotlight Enhancement.
The idea is to use a built-in importer, in this case RichText, to do all the work for you. Note that this will probably need to be repeated on each Operating System install or upgrade.
/System/Library/Spotlight/RichText.mdimporter/Contents/Info.plist and add
... <key>LSItemContentTypes</key> <array> <string>public.rtf</string> <string>public.html</string> <string>public.xml</string> <string>public.plain-text</string> <string>com.apple.traditional-mac-plain-text</string> <string>com.apple.rtfd</string> <string>com.apple.webarchive</string> <string>org.oasis-open.opendocument.text</string> <string>org.openxmlformats.wordprocessingml.document</string> <string>net.daringfireball.markdown</string> </array> ...
You will need an admin password to save the changes.
Restart the Rich Text importer
mdimport -r /System/Library/Spotlight/RichText.mdimporter
And force a Spotlight re-index
sudo mdutil -E /
To test this I created a new Markdown file in BBEdit and added the word
wagga to it. After a few minutes of re-indexing, Spotlight found this file in a
Good to go.
