Description

ai-translated
现有问题
  1. VS Code原生snippet不支持内嵌其他片段，网上$Snippet()语法仅第三方插件可用，换环境插件失效
  2. 光标在单/双引号、圆括号内部时，无法检索、触发code-snippets代码片段，复用片段很麻烦
期望新增功能
  1. 原生支持 ${1:$Snippet(片段prefix)} 语法，自动加载对应prefix的片段并继承下拉占位符
  2. 增加设置开关：允许在字符串引号、括号内部检索、触发代码片段
  3. 支持多段占位符独立跳转，不共享同编号同步编辑冲突
使用场景（我的PowerMill宏开发场景）

我大量复用「元素」下拉片段，在pathname函数参数引号内需要反复输入前缀手动Tab切换，原生不支持嵌套，代码冗余严重。
示例片段：
{
"元素路径": {
"prefix": "pathname = 取激活元素路径",
"body": [
"pathname('${1:$Snippet(元素)}','${2:$Snippet(元素)}'.name)"
]
},
"元素": {
"prefix": "元素",
"body": ["${1|toolpath,tool,Boundary,Pattern|}"]
}
}

替代方案现状

只能拆分占位符到引号外，或安装第三方插件，兼容性差，团队共享片段会出现大量失效。
