Eu estou usando o Ubuntu 18 LTS, gnome-terminal, com o vim 8.0. Quando não estou usando um esquema de cores, o vim parece o mesmo quando é lançado dentro ou fora do tmux:
No entanto, quando eu uso um esquema de cores (neste caso gruvbox), o vim parecerá estranho dentro do tmux:
Como posso consertar isso?
Aqui estão algumas informações básicas:
Meu .vimrc:
" Don't try to be vi compatible
set nocompatible
filetype off
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
" let Vundle manage Vundle, required
Plugin 'VundleVim/Vundle.vim'
"Colorscheme gruvbox https://github.com/morhetz/gruvbox
Plugin 'morhetz/gruvbox'
" Language support pack
Plugin 'sheerun/vim-polyglot'
call vundle#end()
" Indenting https://vi.stackexchange.com/questions/10124/what-is-the-difference-between-filetype-plugin-indent-on-and-filetype-indent
filetype plugin indent on
" set Vim-specific sequences for RGB colors (fixes color bug)
let &t_8f = "\<Esc>[38;2;%lu;%lu;%lum"
let &t_8b = "\<Esc>[48;2;%lu;%lu;%lum"
" fixes glitch? in colors when using vim with tmux
set background=dark
set t_Co=256
" make colors look better
set termguicolors
" enable italic text
let g:gruvbox_italic = '1'
"Set colorscheme to gruvbox
colorscheme gruvbox
" Turn on syntax highlighting
syntax on
" Show line numbers
set number
" Show file stats
set ruler
" Blink cursor on error instead of beeping (grr)
set visualbell
" Enable Mouse
set mouse=a
" show tabs as 4 spaces
set tabstop=4
" convert tabs to spaces
set expandtab
" stop line wrapping (or something similar)
set nowrap
" make side scrolling less jumpy
set sidescroll=1
" Enter inserts new line in normal mode
nmap <S-Enter> O<Esc>
nmap <CR> o<Esc>
Eu também descomentei uma linha no meu bashrc:
# uncomment for a colored prompt, if the terminal has the capability; turned
# off by default to not distract the user: the focus in a terminal window
# should be on the output of commands, not on the prompt
force_color_prompt=yes
Digitar "$ TERM" dentro e fora do tmux retorna o valor "screen-256color".
Além disso, aqui está o meu .tmux.conf:
# remap prefix from 'C-b' to 'C-a'
unbind C-b
set-option -g prefix C-a
bind-key C-a send-prefix
# split panes using | and -
bind \ split-window -h
bind - split-window -v
unbind '"'
unbind %
# switch panes using Alt-arrow without prefix
bind -n M-Left select-pane -L
bind -n M-Right select-pane -R
bind -n M-Up select-pane -U
bind -n M-Down select-pane -D
# Enable mouse mode (tmux 2.1 and above)
set -g mouse on
#256 Color Support?
set -g default-terminal "screen-256color"
