Dynamic snippet evaluation in VSCode

Question

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

I would like a snippet for inserting date and time strings

Answer 1

It's definitely not possible to execute a script or something similar within a snippet.

You can write an extension for Visual Studio Code instead. The extension must implement a CompletionItemProvider.

Its provideCompletionItems method would return a list of CompletionItems. Their filterText properties would be set to the texts displayed in the suggestion box (for example "date" or "time") and their insertText properties would be set to the dynamically computed values.

Finally you would need to register the completion provider using registerCompletionItemProvider.

You should absolutely take a look on how to create an extension before you start: https://code.visualstudio.com/docs/extensions/example-hello-world
