领导者映射以切换vim设置

Question

There are several Vim settings I love, but are too annoying to always enable. For example:

• set relativenumber - annoying when scrolling
• set list - distracting when you don't need it

What is a concise leader mapping to toggle a generic Vim setting?

Answer 1

You have two ways, as described in the help:

                                                           :set-! :set-inv
:se[t] {option}!   or
:se[t] inv{option}      Toggle option: Invert value. {not in Vi}

Either

:set list!

Or

:set invlist

Will do the same.

Answer 2

Toggle options by appending ! to :set <option>

For example, to toggle relativenumber :

nnoremap <leader>r :set relativenumber!<cr>
