Answer 1

I just discovered why I was having a lot of confusion. I, like others here, was having a difficult time getting the default-terminal setting to take effect. I remembered that I had a tmux session in the background. I re-attached my session, closed out my processes, and closed ALL tmux processes. The next time I restarted tmux the default-terminal setting in .tmux.conf began to take effect. I don't know if others are doing this as well but I recommend closing all tmux processes before modifying the .tmux.conf file.

I got my setup to work on my local machine (OSX 10.9.5 with iTerm2) without any modification to .bashrc or .bash_profile. All I did was add the line set -g default-terminal "xterm-256color" to ~/.tmux.conf and restarted all tmux processes.

I got my remote setup (ssh to Ubuntu 14.04) to work exactly the same way without any modifications to .bashrc. I simply added set -g default-terminal "xterm-256color" to ~/.tmux.conf on my remote machine and restarted all remote tmux processes.

You can test what Vim is seeing by doing echo $TERM from within a tmux session. It kept saying screen as the value until I restarted all tmux processes, at which point it reflected xterm-256color as expected.

Hope that helps.

In case anyone needs 24-bit color support:

Tmux supports 24-bit color as of version 2.2. If your terminal supports 24-bit color, add your terminal to the terminal-overrides setting. For example,

set -ga terminal-overrides ",xterm-256color:Tc"

My environment checklist:

• macOS Sierra 10.12.3
• iTerm2 3.0.14 (Report Terminal Type is xterm-256color)
• neovim 0.1.7 (Enable 24-bit color by adding: xterm-256color to .vimrc)
• tmux 2.3 (Add set -ga terminal-overrides ",xterm-256color:Tc" to .tmux.conf)

Nothing else I need to add in .bashrc or .zshrc.

Hope this could help.

So this a bit on the stale side, but it's might be worth mentioning that using screen will often break the Home and End keys. Using

export TERM="xterm-256color"

in should keep the functionality of these and allow the color scheme (or powerline) to work fine.

Since this is the first result on Google and since none of the above helped..wanted to post this so that someone might find it helpful

in .vimrc:

set background=dark
set t_Co=256

Answer 5

I tried all the solutions above and what finally worked for me is putting the following lines in .tmux.conf:

set -g default-terminal "xterm-256color"
