Unable to construct a query to match JavaDoc

[dabico]

As suggested in an issue I opened in tree-sitter-java, to differentiate between regular block comments and JavaDoc documentation comments, I should write my own custom queries. Here's what I tried in the playground:

Code:

class Main {
	// this is a line comment
    /* this is a documentation comment */
    /** this is a documentation comment */
}

Query:

(block_comment) @capture (.match? @capture "^/**")

However, this does not seem to match any of the block comment nodes in the body. I also tried escaping the pattern as "/\*\*" but that did not work either. Am I missing something?

Never mind, I think I understand what I did wrong. The escapes need to be doubled. The correct query that matches documentation comments is:

Query:

((block_comment) @capture (.match? @capture "^/\\*\\*"))
