Setting up the keybinds is not the most straightforward process. You can manipulate the environment by issuing commands to tmux. Introduction Normally, when you use tmux, multiple virtual windows are displayed in a single 'physical' window. Again, if I am using tmux through ssh, I can still use the keybindings, as if tmux were running locally. iTerm2 is integrated with tmux, allowing you to enjoy a native user interface with all the benefits of tmux's persistence.

Because of limitations in the way Vim handles termguicolors, this means I end up having to manually set t_8f and t_8b values. For MacOS, I chose iTerm2 because it’s able to send a series of hex codes to the terminal via a keybind. The terminal in Tmux is set to screen-256-color.This leads me to believe it is not an issue with the theme, or with Tmux. The theme always works in Neovim (v0.1.4), whether I run in Tmux or in iTerm directly.Some additional details brought out from the comments below: Blank lines also render the background color correctly:Īs a final data point, I ran set termcap to dump the terminal settings and verified that everything matches between when I run Vim in iTerm vs when I run in Tmux. This is probably consistent with other similar questions I've seen. To my eye it looks like the text background color is rendering correctly, and the background color for blank lines renders correctly, but for some reason the background color past the end of the text renders incorrectly.

Now the colors are pretty close, so it might be hard to see, but it's actually very jarring when I'm running full screen with split panes and lots of text.
Everything looks as I expect:īut I end up with strange background issues when I run inside Tmux: Here's what I see when I run Vim in iTerm2 directly. This may not be called from within a Transaction. If this tab is attached to a tmux session, then it may be hidden. You can get a tmuxwindowid from tmuxwindowid(). Tmux windows are represented as tabs in iTerm2. To clarify, there are other questions already answered which address essentially the same problem I am experiencing, but none of the offered solutions ( ttyfast or set t_ut=) fix the issue for me unless I turn termguicolors off. async asyncsettmuxwindowvisible (tmuxwindowid: str, visible: bool) None Hides or shows a tmux window.
As far as my setup is concerned, I'm running Tmux 2.2 (with true color support enabled) inside iTerm2 version 3 on a Mac.
