why gitgutter automaticly add binding to my space menu ? about vim-which-key HOT 2 CLOSED

These mappings are defined by vim-gitgutter, see https://github.com/airblade/vim-gitgutter/blob/2dce8e032b9c1989a41296aaeccc8f17dc83c707/autoload/gitgutter.vim#L123-L131.

vim-which-key would parse these mapping automatically. To override these auto parsed items by defining them explicitly:

let g:which_map.h = {
      \ 'name' : '+help',
      \ 'p': [':echom "hello"', 'echo hello']
      \ }

from vim-which-key.

@4vrel based on your question, I am assuming you want to hide the Gitgutter stuff? If that is the case, then this will work:

let g:which_key_map.h = {'name' : 'which_key_ignore'}
let g:which_key_map.h.p = 'which_key_ignore'
let g:which_key_map.h.s = 'which_key_ignore'
let g:which_key_map.h.u = 'which_key_ignore'
