如何使用正则表达式匹配文档中的大括号？

Question

I use VSCODE 1.41.1 to edit a MediaWiki formatted article with lots of MediaWiki template calls , such as:

{{SOME_TEMPLATE|SOME_ARGUMNET}}

I want to match all {{ and }} brace pairs in that document.

I Have tried:

[{{], [}}]

Interesting for me to note that [{{] works, but only for matching a given single pair (yet I need both pairs in one operation).

How to match braces in a document with regex?

Answer 1

在写这个问题时，我发现这个解决方案似乎工作正常：

[{{]|[}}]

Answer 2

[{{] is a character class that matches an opening brace or ... an opening brace! It is strictly equal to [{] or, depending on your regex flavor, a simple { . Same for [}}] .

A direct matching alternative is: [{]{2}|[}][2}
