commit 01b011d38e2af0e11f03d34d80d4cfae497732da parent 344119439e417839d217f31c6195f996e91ce8a1 Author: Jason Franklin <j_fra@fastmail.us> Date: Fri, 22 Dec 2017 08:45:57 -0500 Have "finAndRevealPath()" fail on no file If a file does not exist for the current buffer, this function should fail with a clear warning message. Here, I improved the messages that this function prints so that it fails gracefully when no path can be determined in the calling context. Diffstat:
