Relocating FileMerge with Xcode 4.3
Today I was thinking about FileMerge because I was talking to someone about diffing files, and FileMerge is the best tool I've seen for that. But I remembered that with Xcode 4.3, the entire /Developer directory was removed. So where did it go? Seems I had to go on a hunt.
The obvious places were out - /Applications, and that's about it these days with the App Store. So I got serious:
$ find /Applications -name FileMerge.app /Applications/Xcode.app/Contents/Applications/FileMerge.app $
What? they put an entire Applications directory under the Xcode.app bundle? Why do that? Well… at least I can get at it and run it. It'd be nice if LaunchBar was able to see inside the app bundles, but I can force that on a custom scan. The next question was the command-line opendiff command.
Turns out, there's a command to "refocus" the location of the Developer Tools:
$ sudo /usr/bin/xcode-select -switch /Applications/Xcode.app/Contents/Developer
After this, the opendiff command works exactly as you'd expect. Good enough. They were lost (for a bit), but now they are found.
