~/.vimrc 配置基础

自动补全

补全工具有YouCompleteMe / deoplete 等。
本文使用deoplete，支持异步搜索补全内容。使用不同的插件补全不同的语言内容

配置

if has('nvim')
  Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }
else
  Plug 'Shougo/deoplete.nvim'
  Plug 'roxma/nvim-yarp'
  Plug 'roxma/vim-hug-neovim-rpc'
endif
let g:deoplete#enable_at_startup = 1

安装 python3 的插件工具

pip3 install --user pynvim

语法检查[lint]

语法检查工具有 ale / vim-polyglot等。
在github上查询，ale的start及fork 数量远多于vim-polyglot。因而选前者。

Plug 'w0rp/ale'

let g:ale_linters = {
    'javascript': ['eslint'],
    'css': ['stylelint'],
}
let g:ale_fixers = {
    'javascript': ['eslint'],
    'css': ['stylelint'],
}
let g:ale_fix_on_save = 1

let g:ale_sign_column_always = 1
let g:ale_sign_error = '●'
let g:ale_sign_warning = '?'

nmap <silent> <C-k> <Plug>(ale_previous_wrap)
nmap <silent> <C-j> <Plug>(ale_next_wrap)

全局搜索

常用的插件有 ctrlp / the_silver_searcher / ag.vim / mru.vim 等。
其中，the_silver_searcher在的github的star 最多，使用这个插件。

代码注释

使用NerdCommenter

Plug 'scrooloose/nerdcommenter'

# <leader>c<space> 注释/取消注释
# <leader>cc // 注释
# <leader>cm 只用一组符号注释
# <leader>cA 在行尾添加注释
# <leader>c$ /* 注释 */
# <leader>cs /* 块注释 */
# <leader>cy 注释并复制
# <leader>ca 切换 // 和 /* */
# <leader>cu 取消注释

         }

let g:NERDAltDelims_javascript = 1

Git 集成

vim-gitgutter
vim-fugitive
后者start更多一些
