【vimsolo】让vim看起来像VSCode：颜色主题和状态栏的配置-Toy模板网

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

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

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。文章来源地址https://www.toymoban.com/news/detail-449073.html
