battery.vim is a statusline or tabline component for Neovim/Vim. It uses a job feature of Neovim/Vim to retrieve battery informations so that the plugin won't block the main thread. It supports macOS, Windows, and Linux.

The implementation was translated to Vim script from a Bash script found on https://github.com/b4b4r07/dotfiles/blob/master/bin/battery.

Use junegunn/vim-plug or Shougo/dein.vim like:

" Plug.vim
Plug 'lambdalisue/battery.vim'

" dein.vim
call dein#add('lambdalisue/battery.vim')

Or copy contents of the repository into your runtimepath manually.

Use battery#component() like:

set statusline=...%{battery#component()}...
set tabline=...%{battery#component()}...

Or with itchyny/lightline.vim

let g:lightline = {
      \ ...
      \ 'component_function': {
      \   ...
      \   'battery': 'battery#component',
      \   ...
      \ },
      \ ...
      \}

Additionally, assign 1 to corresponding variables to immediately reflect the changes to statusline or tabline.

let g:battery#update_tabline = 1    " For tabline.
let g:battery#update_statusline = 1 " For statusline.
