测试版本
VIM - Vi IMproved 9.1 (2024 Jan 02, compiled Jan 7 2025 14:30:02)

测试脚本
#!/usr/bin/env bash
cnt=0
> startup.txt
while true
do
vim --not-a-term --startuptime startup.txt -c q
cnt=$((cnt+1))
if [[ "$cnt" -gt "$1" ]];then
break
fi
done
total=$(awk '/editing files in windows/ {sum += $1} END {print sum}' startup.txt)
printf "%.3f ms\n" $(echo "$total/$cnt" | bc -l)
声明
个人优化方面基于vim9script，且需要牺牲一定实用性，不过也有所收获

个人优化思路
要想优化启动速度，个人认为首先是尽可能减少默认加载的耗时，其次是尽可能优化使用的插件数量。
目前我的优化思路是默认耗时较长的尽可能直接替换或者精简，个人插件全部使用vim9script版本
默认加载优化
默认加载比较耗时的，目前我修改了filetype.vim以及优化了语法高亮的一些逻辑
- filetype.vim
目前我测试的版本，filetype.vim文件有3353行内容，该版本提供的全面的文件类型，同时也增加了启动速度。
个人根据日常使用精简了一个版本，可以根据实际需要添加
vim9script noclear
if exists("g:did_load_filetypes")
finish
endif
g:did_load_filetypes = 1
augroup filetypedetect
au BufNewFile,BufRead *.asm,*.[sS] setf asm
au BufNewFile,BufRead *.c setf c
au BufNewFile,BufRead *.rs setf rust
au BufNewFile,BufRead *.cxx,*.c++,*.cc,*.hpp,*.h setf cpp
au BufNewFile,BufRead *.py,*.pyw setf python
au BufNewFile,BufRead *.md setf markdown
au BufNewFile,BufRead .shrc,.bashrc,bashrc,bash.bashrc,.bash[_-]profile,.bash[_-]logout,.bash[_-]aliases,.bash[_-]history,*.bash setf bash
au BufNewFile,BufRead [mM]akefile.am,GNUmakefile.am setf automake
au BufNewFile,BufRead CMakeLists.txt,*.cmake,*.cmake.in setf cmake
au BufNewFile,BufRead configure.in,configure.ac setf config
au BufNewFile,BufRead *.diff,*.rej,*.patch setf diff
au BufNewFile,BufRead *.dts,*.dtsi setf dts
au BufNewFile,BufRead COMMIT_EDITMSG,MERGE_MSG,TAG_EDITMSG,NOTES_EDITMSG,EDIT_DESCRIPTION setf gitcommit
au BufNewFile,BufRead *[mM]akefile*,*.mk,*.mak,Kbuild setf make
au BufNewFile,BufRead {.,}tmux*.conf* setf tmux
au BufNewFile,BufRead Kconfig,Kconfig.*,Config.in.* setf kconfig
au BufNewFile,BufRead $VIMRUNTIME/doc/*.txt setf help
au BufNewFile,BufRead *.txt
\ if getline('$') !~ 'vim:.*ft=help'
\| setf text
\| endif
runtime! ftdetect/*.vim
augroup END
au filetypedetect BufNewFile,BufRead,StdinReadPost *
\ if !did_filetype() && empty(win_gettype())
\| try | exe 'setf ' .. expand("<amatch>:e") | catch | endtry
\| endif
需要注意的是，最后一个事件会将没有指明文件类型的使用文件名后缀设置。比如我没有指定sh后缀的文件会根据规则设置成setf sh，个人感觉简单够用
对于检测不对的情况我一般遇到手动设置，如果次数多了就手动增加到filetype.vim里，会存在一定麻烦
- 语法高亮

g:colors_name = 'gruvbox'

需要注意，该配色并非移植，所以并不通用。另外结合实际场景省略了highlight clear减少不必要加载时间
一般情况下使用配色的步骤是在.vimrc如下配置
syntax on
colorscheme xxx
我研究了一下syntax.txt里关于加载顺序时发现，可以如下设置
g:colors_name = 'gruvbox'
syntax enable
机制在于syntax enable或者syntax on会调用VIMRUNTIME/syntax/syntax.vim，然后在VIMRUNTIME/syntax/synload.vim18行如下：
" Set the default highlighting colors. Use a color scheme if specified.
if exists("colors_name")
exe "colors " . colors_name
else
runtime! syntax/syncolor.vim
endif
此外根据说明发现colorscheme命令每次都会调用$VIMRUNTIME/colors/lists/default.vim，该脚本个人测试耗时0.7ms
个人优化加载顺序，并且配色统一使用rgb数值指定颜色的情况下，直接删除内容保存文件就可以节约不必要启动时间
减少不必要插件启动
vim启动后通过scriptnames可以查看加载的vim脚本，个人只保留$VIMRUNTIME/plugin/目录下的netrwPlugin.vim（虽然保留也基本不用)，删除其余的
默认情况下建议同时保留matchparen.vim，个人是因为精简了一版vim9script版本，主要原因是工作场景下会偶现报错(使用0tab term和1tab term开启两个终端，tabnew打开文件，使用tabnext来回切换)
有类似问题的可以留意注释，插件内容如下
- plugin/matchparen.vim
vim9script noclear
if exists("g:matchparen")
finish
endif
g:matchparen = 1
import autoload '../autoload/matchparen.vim'
augroup matchparen
autocmd!
autocmd! CursorMoved,CursorMovedI * matchparen.Highlight_Matching_Pair()
augroup END
- autoload/matchparen.vim
vim9script noclear
export def Highlight_Matching_Pair()
var [c, c2, flags] = ['', '', '']
var [idx, stopline, timeout] = [0, 0, 300]
var c_lnum = line('.')
var c_col = col('.')
var stoplinebottom = line('w$')
var stoplinetop = line('w0')
var plist = ['(', ')', '{', '}', '[', ']']
if !exists("w:matchparen_ids")
w:matchparen_ids = []
w:paren_hl_on = 0
endif
Remove_Matches()
#个人filetype.vim里检测win_gettype()类型，所以用empty(&ft)判断，常规可以用!empty(win_gettype())
if pumvisible() || empty(&ft)
return
endif
c = getline(c_lnum)->strpart(c_col - 1)->slice(0, 1)
idx = index(plist, c)
if idx < 0
return
endif
if idx % 2 == 0
flags = 'nW'
c2 = plist[idx + 1]
stopline = stoplinebottom
else
flags = 'nbW'
c2 = c
c = plist[idx - 1]
stopline = stoplinetop
endif
if c == '['
c = '\['
c2 = '\]'
endif
if mode() == 'i' || mode() == 'R'
timeout = 60
endif
var [m_lnum, m_col] = searchpairpos(c, '', c2, flags, '', stopline, timeout)
if m_lnum > 0 && m_lnum >= stoplinetop && m_lnum <= stoplinebottom
add(w:matchparen_ids, matchaddpos('MatchParen', [[c_lnum, c_col], [m_lnum, m_col]], 10))
w:paren_hl_on = 1
endif
enddef
export def Remove_Matches()
if w:paren_hl_on
while !empty(w:matchparen_ids)
silent! remove(w:matchparen_ids, 0)->matchdelete()
endwhile
w:paren_hl_on = 0
endif
enddef
关于文件替换个人封装了一个命令
def Clean()
var from = expand("<script>:p:h") .. "/filetype.vim"
var to = expand("$VIMRUNTIME/filetype.vim")
var dir = expand("$VIMRUNTIME/plugin/")
var whitelist = ["netrwPlugin.vim"]
if filereadable(from) && filereadable(to)
delete(to)
filecopy(from, to)
endif
from = expand("<script>:p:h") .. "/default.vim"
to = expand("$VIMRUNTIME/colors/lists/default.vim")
if filereadable(from) && filereadable(to)
delete(to)
filecopy(from, to)
endif
for file in readdir(dir)
(whitelist->index(file) != -1) ?? delete(dir .. file)
endfor
enddef
command! -nargs=0 PluginClean Clean()
对于大型插件懒加载的一种方式
例如lsp补全插件
vim9script
# yegappan/lsp
def LazyLoad()
packadd lsp
inoremap <expr> <Tab> pumvisible() ? "\<C-n>" : "\<Tab>"
inoremap <M-n> <Cmd>LspShowSignature<CR>
nnoremap <M-k> <Cmd>LspHover<CR>
set tagfunc=lsp#lsp#TagFunc
var lspOpts = {
autoHighlightDiags: false,
showSignature: false,
noNewlineInCompletion: true,
showInlayHints: true,
}
g:LspOptionsSet(lspOpts)
var lspServers = [
{
filetype: ['c', 'cpp'],
path: 'clangd',
args: ['--background-index'],
},
# {
# filetype: ['rust'],
# path: 'rust-analyzer',
# args: [],
# syncInit: v:true,
# },
]
g:LspAddServer(lspServers)
enddef
timer_start(0, (timer) => {
LazyLoad()
timer_stop(timer)
})
最后
多年前的憧憬，目前看来也只是个起点。个人插件也是按需实现，就不做介绍
现在入门也更推荐neovim（不由想起刚工作那会，别人开发用vim7.4，我只是编了个vim8.0就暗自窃喜）
