如何配置vscode-neovim插件兼容VS Code的展开/收缩选中功能？

以下是几种可行的配置方案，让Neovim能正确识别VS Code展开/收缩操作生成的选区：

方案1：自定义键盘映射，联动VS Code命令与Neovim状态 #

修改VS Code的settings.json，将展开/收缩选区的快捷键绑定为先执行VS Code的选区操作，再强制切换Neovim到可视化模式，确保选区状态同步：

{
  "keybindings": [
    {
      "key": "ctrl+shift+right", // 可根据你的习惯修改快捷键
      "command": "runCommands",
      "args": {
        "commands": [
          "editor.action.smartSelect.expand",
          "vscode-neovim.enter-visual-mode"
        ]
      },
      "when": "editorTextFocus"
    },
    {
      "key": "ctrl+shift+left", // 可根据你的习惯修改快捷键
      "command": "runCommands",
      "args": {
        "commands": [
          "editor.action.smartSelect.shrink",
          "vscode-neovim.enter-visual-mode"
        ]
      },
      "when": "editorTextFocus"
    }
  ]
}

方案2：通过Neovim配置自动同步选区 #

在你的Neovim配置文件（init.lua或init.vim）中添加自动命令，当进入可视化模式时同步VS Code的选区标记：

Lua配置（init.lua） #

vim.api.nvim_create_autocmd("User", {
  pattern = "VisualModeEnter",
  callback = function()
    local vscode_range = vim.fn["vscode-neovim#getVisualSelection"]()
    if vscode_range then
      vim.fn.setpos("'<", {0, vscode_range.start.line, vscode_range.start.character + 1, 0})
      vim.fn.setpos("'>", {0, vscode_range.end.line, vscode_range.end.character + 1, 0})
    end
  end
})

Vimscript配置（init.vim） #

autocmd User VisualModeEnter * call s:sync_vscode_selection()
function! s:sync_vscode_selection()
  let vscode_range = vscode-neovim#getVisualSelection()
  if !empty(vscode_range)
    call setpos("'<", [0, vscode_range.start.line, vscode_range.start.character + 1, 0])
    call setpos("'>", [0, vscode_range.end.line, vscode_range.end.character + 1, 0])
  endif
endfunction

方案3：调用插件内置的选区同步命令 #

利用vscode-neovim.sync-visual-selection命令，在执行展开/收缩后强制同步选区到Neovim：

{
  "keybindings": [
    {
      "key": "ctrl+shift+right",
      "command": "runCommands",
      "args": {
        "commands": [
          "editor.action.smartSelect.expand",
          "vscode-neovim.sync-visual-selection"
        ]
      },
      "when": "editorTextFocus"
    },
    {
      "key": "ctrl+shift+left",
      "command": "runCommands",
      "args": {
        "commands": [
          "editor.action.smartSelect.shrink",
          "vscode-neovim.sync-visual-selection"
        ]
      },
      "when": "editorTextFocus"
    }
  ]
}
