VSCode 中的动态代码段评估

片段是否可以在 Visual Studio Code 中插入动态计算的完成或片段?

Is it possible for a snippet to insert a dynamically computed completion or snippet in Visual Studio Code?

我想要一个用于插入各种格式的日期和时间字符串的片段.例如，如果您键入 date，则 ISO 格式的当前日期将自动展开.

I would like a snippet for inserting date and time strings of various formats. For example if you type date, the current date in ISO format would automatically be expanded.

Sublime Text 中有一个工具可以通过 EventListener 类中的 rel="noreferrer">on_query_completions 方法.实现将非常简单:

There is a facility in Sublime Text to do this in the python API via the on_query_completions method in the EventListener class. There the implementation would be very simple:

def on_query_completions(self, view, prefix, locations):
  if prefix == 'date':
    val = datetime.now().strftime('%Y-%m-%d')
  return [(prefix, prefix, val)] if val else []

我已阅读有关 用户定义代码段 的文档，但似乎可以仅插入带有用户填写的制表位和变量的预定义文本.

I have read the documentation on User Defined Snippets, but it appears that one can only insert pre-defined text with tab-stops and variables that the user fills in.

如果使用代码段 API 公开的功能无法做到这一点，我能否通过较低级别的插件/扩展 API 实现类似的功能?

If this isn't possible with the functionality exposed by the snippet API, would I be able to implement something similar with via a lower-level plugin/extension API?

我确实意识到有一个名为 插入日期和时间 但这是通过命令托盘而不是动态扩展来工作的.

I do realize that there is an existing extension called Insert Date and Time but this works via the command pallet instead of a dynamic expansion.
