问题描述
限时送ChatGPT账号..在行尾附加(或删除)分号是一种常见的操作.然而像 A;
这样的命令会修改当前光标位置,这并不总是理想的.
Appending (or removing) a semicolon to the end of the line is a common operation. Yet commands like A;
modify the current cursor position, which is not always ideal.
是否有一种直接的方法来映射命令(例如 ;;
)来切换分号是否出现在行尾?
Is there a straightforward way to map a command (e.g. ;;
) to toggle whether a semicolon appears at the end of a line?
我目前在我的 vimrc 中使用这个命令来追加:
I'm currently using this command in my vimrc to append:
map ;; A;<Esc>
推荐答案
这样的事情会起作用
nnoremap ;; :s/\v(.)$/\=submatch(1)==';' ? '' : submatch(1).';'<CR>
这使用了一个替代命令并检查最后一个字符是否是分号,如果是,则将其删除.如果它不是将其附加到匹配的字符.这在替换部分使用 \=
来执行 vim 表达式.
This uses a substitute command and checks to see if the last character is a semicolon and if it is it removes it. If it isn't append it to the character that was matched. This uses a \=
in the replacement part to execute a vim expression.
如果您不想匹配任何任意字符,您可以将其包装在一个函数中并传入您想要匹配的字符.
If you wan't to match any arbitrary character you could wrap it in a function and pass in the character you wanted to match.
function! ToggleEndChar(charToMatch)
s/\v(.)$/\=submatch(1)==a:charToMatch ? '' : submatch(1).a:charToMatch
endfunction
然后映射将切换分号.
nnoremap ;; :call ToggleEndChar(';')<CR>
