我不相信有一种“简单”的方法可以做到这一点(也就是说,具有严格的内置功能),但一个简单的函数就可以了。在您的.vimrc
文件中:
function! DoIndent()
" Check if we are at the *very* end of the line
if col(".") == col("$") - 1
let l:needsAppend = 1
else
let l:needsAppend = 0
endif
" Move to location where insert mode was last exited
normal `^
" Save the distance from the first nonblank column
let l:colsFromBlank = col(".")
normal ^
let l:colsFromBlank = l:colsFromBlank - col(".")
" If that distance is less than 0 (cursor is left of nonblank col) make it 0
if l:colsFromBlank < 0
let l:colsFromBlank = 0
endif
" Align line
normal ==
" Move proper number of times to the right if needed
if l:colsFromBlank > 0
execute "normal " . l:colsFromBlank . "l"
endif
" Start either insert or line append
if l:needsAppend == 0
startinsert
else
startinsert!
endif
endfunction
" Map <Tab> to call this function
inoremap <Tab> <ESC>:call DoIndent()<CR>
