Setup and introduce Tmux so that I can use it

Cheat Sheet

Image source is in the image

Enable 256 color vim

From https://superuser.com/a/1459904

First, outside tmux, you need:

export TERM=xterm-256color

in .tmux.conf:

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

And don't forget to source config manually:

tmux source-file ~/.tmux.conf

All above make sure tmux have full 256 colors support.

And in your vimrc, add:

if exists("$TMUX")
    set t_Co=256
    set notermguicolors
else
    set termguicolors
endif

Enable True Color for vim

From tmux/tmux#1246 and https://github.com/lifepillar/vim-solarized8#troubleshooting

Basically,

let &t_8f = "\<Esc>[38;2;%lu;%lu;%lum"
let &t_8b = "\<Esc>[48;2;%lu;%lu;%lum"
set termguicolors

will do the trick.

Resize Panes on Keyboard

You may just use mouse though

This assumes that you've hit ctrl + b and : to get to the command prompt

:resize-pane -D (Resizes the current pane down)
:resize-pane -U (Resizes the current pane upward)
:resize-pane -L (Resizes the current pane left)
:resize-pane -R (Resizes the current pane right)
:resize-pane -D 10 (Resizes the current pane down by 10 cells)
:resize-pane -U 10 (Resizes the current pane upward by 10 cells)
:resize-pane -L 10 (Resizes the current pane left by 10 cells)
:resize-pane -R 10 (Resizes the current pane right by 10 cells)

Border Chaos

If I split the panes vertically, the first column of the right pane is overwritten by the border.

It turns out to be the old problem with MinTTY. As you can see on the top-middle of the screenshot, the border is displayed in full width (2 chars), with introduced the chaos.

To solve it, inspired by mintty/mintty#615, all you need to do is Options → Text → Locale: C (Or any language with sane character width). And the broken vim airline is solved too!
