javascript not match function definition

[nick357]

export function add(c, d) { return c + d }

add(1, 2)

add($$$A) can not match export function add(c, d)

can provide an option to search only for definitions and/or only for calls?

Environment
ast-grep 0.33.0

Hi, ast-grep is a structural search tool based on AST.
https://ast-grep.github.io/advanced/pattern-parse.html#pattern-is-ast-based

add() and function add() are two different types of AST nodes. Comparing them equally is not possible in the sense of tree structure.

For your use case, you may want to try some semi structural search tool like Comby.

My question is whether this search plugin can support simple options to find function definitions and function calls. In everyday development, matching definitions and implementations is a very common requirement.

For example, if I enter "add" in the search box, by checking or selecting function definition and function call, the underlying call would be the following two corresponding rules.

No, the feature should covered by #167
