After upgrading ST3 to build 3065 I'm no longer able to launch it via the terminal:
[11:53:31] ❯ /Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl .
Unable to launch Sublime Text
I've shown the absolute path just so nobody thinks it's a symlink issue.
The previous version of ST3 (build 3059, IIRC) did not have this issue.
subl -h
works as expected and prints the help properly. Really, all the cli flags work except opening files. Explicitly providing a single file argument gives the same result.
Removing the following did the trick (not sure if it was specifically one of these, so listing all):
~/Library/Caches/com.sublimetext.3
~/Library/Preferences/com.sublimetext.3.plist
And then restarting ST3. Why they maintained a link to the old app, I cannot say.
Thanks to @Paul R. for helping to point me in the right direction.
