Building esquery selectors using sample code

#1

Hi all, I remember a library that would automatically build an esquery selector for you based on some sample code with an underscore, e.g. var x = 1 + _ might build a selector like BinaryExpression Literal:nth-child(2)

Does anyone remember the name?

#2

For a little more context, imagine the source code is: var example = 3

Then you use this sample code with the underscore (placeholder accepted anywhere an identifier will go): var example = _

It will product the selector:

VariableDeclaration > VariableDeclarator[id.name="example"] .init

Then when you use this selector with the source code, you find:

{
  "type": "Literal",
  "value": 3,
  "raw": "3"
}
