Written originally to navigate around the Swift source project, SearchLight is a small macOS utility that helps you form a new relationship with your Macs disk. Quickly find files rather than stumble across them buried in deep in the filesystem.
When searching for some text, it displays the filename and full path as links that can be clicked on. After each file it "greps" out the line in the file where the match occurs so you can see if it is relevant before opening the file. Inside the display of the match is a link which takes you to a preview of the file, navigating directly to that point in the file where the match occurred.
All searches are lightning fast using the same index “meta data” as Spotlight and all in all it makes for a streamlined search experience. Add the app as a login item to have SearchLight always available on your menubar. After that, it operates as a service so you can initiate a search for any text from inside any application.
