【vimsolo】让vim看起来像VSCode：颜色主题和状态栏的配置

1. 目的

习惯了 VSCode 默认的配色黑色主题蓝色状态栏。偶尔使用 Vim 时想让 vim 伪装的像 VSCode不考虑花里花哨的插件和动态效果静态效果上让 vim 看起来像 VSCode怎样实现呢

2. 理念 vimsolo

vimsolo = vim + solo除了颜色主题可以用第三方插件 其他配置都用 .vimrc 手工完成不依赖库插件。

vimsolo 的理念是 vim 插件如果装多了配置繁杂受网络影响较大还需要适配不同 vim/nvim 版本和 nerdfont 字体 而是极致的简洁。

3. vimrc: 配置颜色

VSCode 颜色主题的 vim 插件有好几个 我用的是 codedark https://github.com/tomasiser/vim-code-dark

vimrc 中的配置代码:

"--- color theme
set background=dark
try
    set t_Co=256
    set t_ut=
    colorscheme codedark
    ""colorscheme molokai
catch
    try
        colorscheme desert
    catch
        colorscheme peaksea
    endtry
endtry

用 vim 打开 Python 文件看看效果:

4. vimrc: 配置状态栏

状态栏的插件有很多很容易陷入选择的困境因为都太漂亮了而一一尝试和配置会花费不少时间但容易漂浮在插件开发者配置的表层。其实基于 vimL 徒手可以写一个 statuline

• 本质是给变量 statusline 赋值
• 把 statueline 拆分为n部分每部分是一个字符串变量变量之间用 . 连接起来
• 每部分大都可以从 vim 自带的变量或函数获取到例如文件编码是 let l:encoding = ' %{&fenc} '

具体配置 vimL 脚本如下

"======================================================================
" statusline
"======================================================================
"--- https://bruhtus.github.io/posts/vim-statusline/
"--- https://jdhao.github.io/2019/11/03/vim_custom_statusline/
" component for active window
function! StatuslineActive()
  " if we want to add `f` items in our statusline

let g:currentmode={
       \ 'n'  : 'NORMAL',
       \ 'v'  : 'VISUAL',
       \ 'V'  : 'V·Line',
       \ "\<C-V>" : 'V·Block',
       \ 'i'  : 'INSERT',
       \ 'R'  : 'R',
       \ 'Rv' : 'V·Replace',
       \ 'c'  : 'Command',
       \}

  "let l:current_mode = mode()
  let l:current_mode = ' ['.'%{toupper(g:currentmode[mode()])}'.'] '
  " if we want to add 'm' items in our statusline
  let l:cursor_position = ' Ln %l, Col %c'
  let l:indentation = ' %{(&expandtab=="1") ? "Spaces: ".&tabstop : "Tabs: ".&tabstop} '
  let l:encoding = ' %{&fenc} '
  let l:end_of_line_sequence = ' %{(&fileformat=="dos")? "CRLF" : "LF"} '
  let l:percent = ' %p%% '
  let l:language_mode = '%{&filetype}'
  " the `.` is basically to ignore whitespace before and put it right after the previous component
  let l:statusline_left = l:current_mode
  let l:statusline_middle = ''
  let l:statusline_right = l:cursor_position.l:indentation.l:encoding.l:end_of_line_sequence.l:percent.l:language_mode
  return l:statusline_left.'%='.l:statusline_middle.'%='.l:statusline_right
endfunction

" component for inactive window
function! StatuslineInactive()
  " the component goes here
endfunction

" load statusline using `autocmd` event with this function
function! StatuslineLoad(mode)
  if a:mode ==# 'active'
    " to make it simple, %! is to evaluate the current changes in the window
    " it can be useful for evaluate current mode in statusline. For more info:
    " :help statusline.
    setlocal statusline=%!StatuslineActive()
  else
    setlocal statusline=%!StatuslineInactive()
  endif
endfunction

" so that autocmd didn't stack up and slow down vim
augroup statusline_startup
  autocmd!
  " for more info :help WinEnter and :help BufWinEnter
  autocmd WinEnter,BufWinEnter * call StatuslineLoad('active')
  autocmd WinLeave * call StatuslineLoad('inactive')
augroup END

hi StatusLine ctermbg=32 ctermfg=254 guibg=#007acc guifg=#dfe9ed
"hi StatusLineNC ctermbg=240 ctermfg=240 guibg=#d0d0d0 guifg=#444444

5. 拷贝颜色主题和.vimrc: python安装脚本

使用 Python 编写了安装脚本相比于 shell 脚本开发效率相当高 平台兼容性更强。
