打通Neovim與系統剪切板

1. 如何確認vim和系統剪貼板是否互通

（1) reg 查看寄存器

  (2) 查看+ 和 * 2個寄存器是否有系統剪貼板的內容，如果有表示互通，如果沒有，表示沒有互通

 

2. 打通剪貼板

   (3) 沒有互通，安裝剪貼板工具 xclip

        sudo apt install xclip -y

   (4) 執行第2部的步驟，檢查剪貼板狀況

 

 

neovim中關於剪切板配置的說明：

Clipboard integration 			      *provider-clipboard* *clipboard*

Nvim has no direct connection to the system clipboard. Instead it depends on
a |provider| which transparently uses shell commands to communicate with the
system clipboard or any other clipboard "backend".

To ALWAYS use the clipboard for ALL operations (instead of interacting with
the '+' and/or '*' registers explicitly): >
    set clipboard+=unnamedplus

See 'clipboard' for details and options.

							      *clipboard-tool*
The presence of a working clipboard tool implicitly enables the '+' and '*'
registers. Nvim looks for these clipboard tools, in order of priority:

  - |g:clipboard|
  - pbcopy, pbpaste (macOS)
  - wl-copy, wl-paste (if $WAYLAND_DISPLAY is set)
  - xclip (if $DISPLAY is set)
  - xsel (if $DISPLAY is set)
  - lemonade (for SSH) https://github.com/pocke/lemonade
  - doitclient (for SSH) http://www.chiark.greenend.org.uk/~sgtatham/doit/
  - win32yank (Windows)
  - tmux (if $TMUX is set)

								 *g:clipboard*
To configure a custom clipboard tool, set g:clipboard to a dictionary.
For example this configuration integrates the tmux clipboard: >

    let g:clipboard = {
          \   'name': 'myClipboard',
          \   'copy': {
          \      '+': 'tmux load-buffer -',
          \      '*': 'tmux load-buffer -',
          \    },
          \   'paste': {
          \      '+': 'tmux save-buffer -',
          \      '*': 'tmux save-buffer -',
          \   },
          \   'cache_enabled': 1,
          \ }

If "cache_enabled" is |TRUE| then when a selection is copied Nvim will cache
the selection until the copy command process dies. When pasting, if the copy
process has not died the cached selection is applied.

g:clipboard can also use functions (see |lambda|) instead of strings.
For example this configuration uses the g:foo variable as a fake clipboard: >

    let g:clipboard = {
          \   'name': 'myClipboard',
          \   'copy': {
          \      '+': {lines, regtype -> extend(g:, {'foo': [lines, regtype]}) },
          \      '*': {lines, regtype -> extend(g:, {'foo': [lines, regtype]}) },
          \    },
          \   'paste': {
          \      '+': {-> get(g:, 'foo', [])},
          \      '*': {-> get(g:, 'foo', [])},
          \   },
          \ }

The "copy" function stores a list of lines and the register type. The "paste"
function returns the clipboard as a `[lines, regtype]` list, where `lines` is
a list of lines and `regtype` is a register type conforming to |setreg()|.

 

 

所以我們直接使用自定義剪切板就ok，我們讓+和*寄存器都使用clipboard-provider 腳本來配置。

在neovim的配置中增加以下代碼：

neovim的配置相對較多，如果是spacevim中，可以加到~/.config/nvim/main.vim中

if executable('clipboard-provider')
  let g:clipboard = {
          \ 'name': 'myClipboard',
          \     'copy': {
          \         '+': 'clipboard-provider copy',
          \         '*': 'clipboard-provider copy',
          \     },
          \     'paste': {
          \         '+': 'clipboard-provider paste',
          \         '*': 'clipboard-provider paste',
          \     },
          \ }
endif

 

此時，重啟nvim，應該已經大功告成了。復制時，通過 "+y 命令復制，就可以復制到剪切板。如果不行，可以輸入 :reg ，看相關代碼是否插入到 + 寄存器中。如果在寄存器中，同時你的clipboard-provider 腳本沒問題的話，應該是可以成功復制的。
