Question: How to escape dollar sign?

[Ventzy]

I want to match this js code:

$stateProvider.state('stateName', {})

And if I do this in equery '$stateProvider.state(,)' - $stateProvider is actually named match in equery, so it will match "ANYSTRING.state('stateName', {})". I have tried to esacape it with $stateProvider or with $$stateProvider, but they don't work.

There is no way to do so currently using equery, you can do it some of it with squery:

grasp 'call[callee=member[obj=#$stateProvider][prop=#state]]'

[Ventzy]

With squery am I losing ability to have named matches? I want to use them like matching the first parameter '$stateProvider.state($name,__)'

[Ventzy]

I have made a little patch in grasp-equery/parse.js and it works for my example above with $$stateProvider. I don't know would it work in more complex query as I don't know grasp-equery internals. Here it is:

  function processNode(node){
      ...    
      } else if (that = /^_\$(\w*)$/.exec(name)) {
        ...

      >>> my addition >>>
      } else if (that = /^\$\$(\w+)$/.exec(name)) {
        node.name = node.name.substr(1);
        return;
      <<< my addition <<<

      } else if (that = /^\$(\w+)$/.exec(name)) {
      ....

@gkz Hi, I'd like to confirm with you that not only dollar sign, but even underscore is not really available for lookup with equery, is it not?

[gkz]

A single underscore should work
