From 78352fdd328b611d935ba051288191b33278cc4a Mon Sep 17 00:00:00 2001 From: Nicholas Marriott Date: Tue, 6 Jun 2017 07:59:53 +0100 Subject: Add a small dance to daemon() to reattach tmux to the user's namespace (which allows access to the clipboard) on OS X 10.10 and above. Chis Johnsen has done much work on and documentation of this issue, the code is copied (with some tweaks) from his reattach-to-user-namespace at: https://github.com/ChrisJohnsen/tmux-MacOSX-pasteboard Tested by Enrico Ghirardi. Will see how this goes, if it breaks stuff it might go away again. --- CHANGES | 3 ++ compat/daemon-darwin.c | 85 ++++++++++++++++++++++++++++++++++++++++++++++++++ compat/daemon.c | 10 ++++++ configure.ac | 9 +++++- 4 files changed, 106 insertions(+), 1 deletion(-) create mode 100644 compat/daemon-darwin.c diff --git a/CHANGES b/CHANGES index 9b1cd32c..bcddb9f0 100644 --- a/CHANGES +++ b/CHANGES @@ -1,5 +1,8 @@ CHANGES FROM 2.5 to master +* Do a dance on OS X 10.10 and above to return tmux to the user namespace, + allowing access to the clipboard. + * Do not allow escape sequences which expect a specific terminator (APC, DSC, OSC) to wait for forever - use a small timeout.
