I wrote previously about an idea to use the spotlight search tool in Mac OS X from within emacs. At the time, I put together some pretty crude code to do this, but I have now improved it into a package that I am quite pleased with.
The package gives you a powerful way to call spotlight from emacs. You can do a live search for a string in the text of a file, filter the file list by file name and then open the selected file with a swiper search for your query text.
Here is an example of my using it. In the animation below, I use
M-x spotlight to run a spotlight search for “tomatoes”. Notice how the number of matches updates as I type or delete the last couple of characters. I then use
M-RET to narrow the list of matching files using the string “docs org$” which narrows the list to files with “doc” in their full name, and with names ending in “org”. Finally once I select the file I want,
swiper takes me to the matches of my original “tomatoes” query.
See the README on github for more details.
