How should I make my code snippets not distinguish between uppercase and lowercase letters

Question

I am following this link(https://code.visualstudio.com/api/language-extensions/snippet-guide) to develop the code snippet function of my vscode exetension.

I want my code snippets not distinguish between uppercase and lowercase letters. For example, "Enum"/"ENUM"/"enum"/"eNum"/"eNUm"/...and so on is all I need, how should I configure my "prefix" field（like using regex?）?

Answer 1

You can define multiple prefixes, choose the ones that are the most likely

{
  "Enum snip": {
    "prefix": ["enum", "ENUM", "Enum"],
    "body": ["MyEnum {}"],
    "description": "Enum foo bar."
  }
}

Or you can write a CompletionItemProvider and analyze the text before the cursor with a regex and create a snippet completion item.
