Tmux iterm28/23/2023 ![]() iTerm2 will the translate them when it oughtn’t. Consequently, it will appear to be screen to iTerm2 but xterm to the program that is sending control sequences. bashrc or equivalent, neither tmux nor iTerm2 will be aware of it. If you change your TERM to xterm (or an xterm-family terminal) in your. If it contains the string "screen" then control sequences get translated. ITerm2 automatically determines what terminal tmux is configured to use by querying tmux's default-terminal setting. In order for this to work well, you'll want to disable the screen-> xterm translation in iTerm2. Some users prefer to use TERM=xterm-256color (or any other xterm-family terminal) in tmux. For example, it rewrites italic -> reverse video. Within tmux integration, iTerm2 attempts to detect your TERM and translate screen-style codes into xterm-style codes before processing them.iTerm2 supports xterm-family control sequences.For example, the control sequence that indicates italic text in xterm is used for reverse video in screen. There are two families of terminals: xterm and screen.Your terminal type is determined by the TERM environment variable.Italics show up as reverse video, whole-screen reverse video isn't working, or my $TERM variable is not what I wish Please report them at and attach an as-minimal-as-possible debug log. As of the nightly build or 3.3.7beta3 this should work reasonably well but there might be bugs. Ensure you have the most recent version of tmux installed. Turn on Prefs > Advanced > Allow variable window sizes in tmux integration. Editing the Session Name will not have an effect on the tab title.Ĭontrol sequences in tmux (like \e]0 title\\\e) modify the session name. When you open Edit Session in tmux integration, you can choose to edit either the Session Name or the Tab Title. In a tmux integration session this is surfaced in the per-pane titlebar, which is visible only when there are split panes (if the feature is enabled). ![]() You can edit the name of both in Edit Session > Session Name. Tmux has a concept of a "window pane" which maps onto an iTerm2 "session", sometimes referred to as a "split pane". The previous section described window names and window titles. Put this in your ~/.nf file:Įcho -ne "\033kYour title goes here\007” How do session names work? In iTerm2 3.3.0 and later with tmux 2.9 or later, you can choose to show tmux window titles in native tab and window titles. Prior to iTerm2 3.3.0, only the window name was ever used in the UI. The window title is meant to be the human-readable name that's present in the user interface. The window name is its identifier for applying changes to the window via tmux commands. First, tmux makes a distinction between window names and window titles, which is surprising. The way tmux uses window names and window titles is confusing and kind of an impedance mismatch for iTerm2. I want to see tmux window titles as tab/window titles in iTerm2 The threshold is adjustable in the dashboard itself: If you have eleven, it might just be annoying. If you have a thousand windows, this is probably convenient. If you have more than ten tabs or windows, the dashboard will open. You probably don't need to interact with the tmux gateway session (the one where tmux -CC was run) very often, so it's nice to hide it away. Here's how I like to configure it:īuried sessions are removed from the window and go in the menu under Session > Buried Sessions. If you use ssh instead of Eternal Terminal, configure the session to restart automatically:Ĭheck Prefs > General > tmux. To run tmux locally set the profile’s command like this:įor remote hosts, create a new profile for each machine you run tmux on. Instead, configure your profile to run it. To prevent it, do not run tmux -CC from the command line. While there are mitigations in place to minimize the extent of this problem it cannot be completely fixed. ![]() This means that if tmux suddenly exits or your ssh session dies, iTerm2 will send commands that reach the shell rather than tmux. When you run tmux -CC at the command line, iTerm2 communicates with tmux using in-band signaling. I get random commands after tmux detaches Tcsh and fish users should modify the above as needed for their shells. Export ITERM_ENABLE_SHELL_INTEGRATION_WITH_TMUX=YES
