如何重新映射coc.nvim自动完成键？

Question

我试图更改我的coc.nvim自动完成键，并在堆栈溢出中发现了这问题，但是回答这个问题的人并没有很好地解释如何根据您的需要定制它，所以我将解释它，以帮助那些像我一样绞尽脑汁的NeoVim用户。

示例vim配置为COC提供了一些非常有用的提示。

但对你来说，这是相关的：

" Use tab for trigger completion with characters ahead and navigate.
" NOTE: There's always complete item selected by default, you may want to enable
" no select by `"suggest.noselect": true` in your configuration file.
" NOTE: Use command ':verbose imap <tab>' to make sure tab is not mapped by
" other plugin before putting this into your config.
inoremap <silent><expr> <TAB>
      \ coc#pum#visible() ? coc#pum#next(1) :
      \ CheckBackspace() ? "\<Tab>" :
      \ coc#refresh()
inoremap <expr><S-TAB> coc#pum#visible() ? coc#pum#prev(1) : "\<C-h>"

" Make <CR> to accept selected completion item or notify coc.nvim to format
" <C-g>u breaks current undo, please make your own choice.
inoremap <silent><expr> <CR> coc#pum#visible() ? coc#pum#confirm()
                              \: "\<C-g>u\<CR>\<c-r>=coc#on_enter()\<CR>"

function! CheckBackspace() abort
  let col = col('.') - 1
  return !col || getline('.')[col - 1]  =~# '\s'
endfunction
