From 11430f4a4b3d4b2f6cfc103e574768dbcc64b517 Mon Sep 17 00:00:00 2001 From: Vincent Ambo Date: Sat, 5 Sep 2020 12:40:26 +0100 Subject: fix(term-switcher.el): Explicitly fail if buffers are missing Since upgrading to Emacs 27 I have observed a strange behaviour where this terminal switcher sometimes fails to select a valid buffer, in which case it falls through to the case that just opens a new buffer instead. This is kind of annoying and to aid in debugging this change makes the creation of new buffers explicit and fails if no matching buffer is found. Note that this is likely not a fix for the issue itself, but it will help debug what is going on.
