Simple tmux statusline generator with support for powerline symbols and vim/airline/lightline statusline integration

• colors from vim-airline/lightline.vim

• colors from vim's own statusline

• use vim/vim-airline/lightline.vim colors, so tmux and vim share the same statusline colortheme
• preloaded with stock themes and presets, which can be combined anyway you want
• configure tmux statusline using a simple hash, in case stock presets don't meet your needs
• create a snapshot .conf file which can be sourced by tmux, no need to open vim to set your tmux statusline

Use one of the vim_statusline_* themes (and optionally set in vimrc let g:tmuxline_powerline_separators = 0):

:Tmuxline vim_statusline_1
" or
:Tmuxline vim_statusline_2
" or
:Tmuxline vim_statusline_3

Just start vim inside of tmux. airline's colors will be applied to tmux's statusline

Alternatively, you can set it manually using airline_* themes:

:Tmuxline airline
" or
:Tmuxline airline_insert
" or
:Tmuxline airline_visual

If you set airline theme manually, make sure the airline-tmuxline extension is disabled, so it doesn't overwrite the theme:

let g:airline#extensions#tmuxline#enabled = 0

Use one of the lightline_* themes:

:Tmuxline lightline
" or
:Tmuxline lightline_insert
" or
:Tmuxline lightline_visual

Set a a colortheme and a preset, both arguments are optional

:Tmuxline [theme] [preset]

After running :Tmuxline, create a snapshot file which can be sourced by tmux.conf on startup

:TmuxlineSnapshot [file]

Source the created snapshot in tmux.conf

# in tmux.conf
source-file [file]

# alternatively, check file exists before sourcing it in tmux.conf
if-shell "test -f [file]" "source [file]"

Note that :Tmuxline and :TmuxlineSnapshot are available only when vim is inside a tmux session.

Set g:tmuxline_preset to a stock preset and run :Tmuxline

let g:tmuxline_preset = 'nightly_fox'
" or
let g:tmuxline_preset = 'full'
" or
let g:tmuxline_preset = 'tmux'
" other presets available in autoload/tmuxline/presets/*

Contents of the statusline are configured with a simple hash. Left section is configured with a, b, c, right with x, y, z. cwin and win affect the current (active) window and the in-active windows respectively.

let g:tmuxline_preset = {
      \'a'    : '#S',
      \'b'    : '#W',
      \'c'    : '#H',
      \'win'  : '#I #W',
      \'cwin' : '#I #W',
      \'x'    : '%a',
      \'y'    : '#W %R',
      \'z'    : '#H'}

tmux will replace #X and %X. Excerpts from tmux man page:

#H    Hostname of local host
#h    Hostname of local host without the domain name
#F    Current window flag
#I    Current window index
#S    Session name
#W    Current window name
#(shell-command)  First line of the command's output

string will be passed through strftime(3) before being used.

If the values of the hash g:tmuxline_preset hold an array, a powerline separator will be placed.

let g:tmuxline_preset = {
      \'a'    : '#S',
      \'win'  : ['#I', '#W'],
      \'cwin' : ['#I', '#W', '#F'],
      \'y'    : ['%R', '%a', '%Y'],
      \'z'    : '#H'}

tmux allows using any command in the statusline.

let g:tmuxline_preset = {
      \'a'    : '#S',
      \'c'    : ['#(whoami)', '#(uptime | cut -d " " -f 1,2,3)'],
      \'win'  : ['#I', '#W'],
      \'cwin' : ['#I', '#W', '#F'],
      \'x'    : '#(date)',
      \'y'    : ['%R', '%a', '%Y'],
      \'z'    : '#H'}

Use let g:tmuxline_powerline_separators = 0 to disable using powerline symbols

To fine-tune the separators, use g:tmuxline_separators:

let g:tmuxline_separators = {
    \ 'left' : '',
    \ 'left_alt': '>',
    \ 'right' : '',
    \ 'right_alt' : '<',
    \ 'space' : ' '}

Note that vim-airline has a tmuxline extension which by default sets airline's color theme onto tmuxline. If you don't want airline colors in tmuxline, set let g:airline#extensions#tmuxline#enabled = 0 in vimrc.

Modifying g:tmuxline_theme (details below) makes sense only if the airline-tmuxline is not enabled.

Use g:tmuxline_theme to configure the theme. g:tmuxline_theme can hold either a string (stock theme) or a hash (custom theme).

let g:tmuxline_theme = 'icebert'
" or
let g:tmuxline_theme = 'zenburn'
" or
let g:tmuxline_theme = 'jellybeans'
" other themes available in autoload/tmuxline/themes/*

Alternatively, g:tmuxline_theme can be used to fine tune a custom theme:

let g:tmuxline_theme = {
    \   'a'    : [ 236, 103 ],
    \   'b'    : [ 253, 239 ],
    \   'c'    : [ 244, 236 ],
    \   'x'    : [ 244, 236 ],
    \   'y'    : [ 253, 239 ],
    \   'z'    : [ 236, 103 ]
    \   'win'  : [ 103, 236 ],
    \   'cwin' : [ 236, 103 ],
    \   'bg'   : [ 244, 236 ],
    \ }
" values represent: [ FG, BG, ATTR ]
"   FG ang BG are color codes
"   ATTR (optional) is a comme-delimited string of one or more of bold, dim, underscore, etc. For details refer to 'message-attr attributes' in tmux man page

The plugin's files follow the standard layout for vim plugins.

• Pathogen git clone https://github.com/edkolev/tmuxline.vim ~/.vim/bundle/tmuxline.vim
• Vundle Bundle 'edkolev/tmuxline.vim'
• NeoBundle NeoBundle 'edkolev/tmuxline.vim'
• Vim-Plug Plug 'edkolev/tmuxline.vim'

• Paul Rouget's desktop setup
• Bailey Ling's vim-airline

Vimscript wasn't my first choice of language for this plugin. Arguably, bash would have been better suited for this task. I chose vimscript because:

• its data scructures (arrays, hashes) are better than their bash counterparts (easier to write, to maintain). So maintaining your tmux statusline as a vim hash would be easier
• vim has (better) package managers

Somewhat-similar plugins:

• powerline is a great project. Still, my Raspberry Pi chokes while executing python every 2 seconds (I haven't tried powerline's daemon mode). I also find it a bit hard to personalize
• tmux-powerline doesn't focus on easy customization but on adding extra information (segments) in tmux (gmail, weather, earthquake warnings, etc)
