flow CLI autocomplete command and get-def command doesn't recognize methods and properties of an object that starts with "$" ( dollar char )

[pichillilorenzo]

For example I have this piece of code on a file called test.js:

// @flow

let a = {
  $test: 3
}
a.AUTO332

If I execute flow autocomplete --json --pretty < test.js, it gives me only:

{
  "result":[
    {
      "name":"hasOwnProperty",
      "type":"(prop: any) => boolean",
      "func_details":{"return_type":"boolean","params":[{"name":"prop","type":"any"}]},
      "path":"/private/tmp/flow/flowlib_32caa231/core.js",
      "line":50,
      "endline":50,
      "start":5,
      "end":38
    },
    {
      "name":"isPrototypeOf",
      "type":"(o: any) => boolean",
      "func_details":{"return_type":"boolean","params":[{"name":"o","type":"any"}]},
      "path":"/private/tmp/flow/flowlib_32caa231/core.js",
      "line":51,
      "endline":51,
      "start":5,
      "end":34
    },
    {
      "name":"propertyIsEnumerable",
      "type":"(prop: any) => boolean",
      "func_details":{"return_type":"boolean","params":[{"name":"prop","type":"any"}]},
      "path":"/private/tmp/flow/flowlib_32caa231/core.js",
      "line":52,
      "endline":52,
      "start":5,
      "end":44
    },
    {
      "name":"toLocaleString",
      "type":"() => string",
      "func_details":{"return_type":"string","params":[]},
      "path":"/private/tmp/flow/flowlib_32caa231/core.js",
      "line":53,
      "endline":53,
      "start":5,
      "end":28
    },
    {
      "name":"toString",
      "type":"() => string",
      "func_details":{"return_type":"string","params":[]},
      "path":"/private/tmp/flow/flowlib_32caa231/core.js",
      "line":54,
      "endline":54,
      "start":5,
      "end":22
    },
    {
      "name":"valueOf",
      "type":"() => Object",
      "func_details":{"return_type":"Object","params":[]},
      "path":"/private/tmp/flow/flowlib_32caa231/core.js",
      "line":55,
      "endline":55,
      "start":5,
      "end":21
    }
  ]
}

without the $test property.

If I change the property name from $test to t$est it works:

// @flow

let a = {
  t$est: 3
}
a.AUTO332

So, executing again flow autocomplete --json --pretty < test.js, it gives me:

{
  "result":[
    {
      "name":"hasOwnProperty",
      "type":"(prop: any) => boolean",
      "func_details":{"return_type":"boolean","params":[{"name":"prop","type":"any"}]},
      "path":"/private/tmp/flow/flowlib_32caa231/core.js",
      "line":50,
      "endline":50,
      "start":5,
      "end":38
    },
    {
      "name":"isPrototypeOf",
      "type":"(o: any) => boolean",
      "func_details":{"return_type":"boolean","params":[{"name":"o","type":"any"}]},
      "path":"/private/tmp/flow/flowlib_32caa231/core.js",
      "line":51,
      "endline":51,
      "start":5,
      "end":34
    },
    {
      "name":"propertyIsEnumerable",
      "type":"(prop: any) => boolean",
      "func_details":{"return_type":"boolean","params":[{"name":"prop","type":"any"}]},
      "path":"/private/tmp/flow/flowlib_32caa231/core.js",
      "line":52,
      "endline":52,
      "start":5,
      "end":44
    },
    {
      "name":"t$est",
      "type":"number",
      "func_details":null,
      "path":"-",
      "line":4,
      "endline":4,
      "start":10,
      "end":10
    },
    {
      "name":"toLocaleString",
      "type":"() => string",
      "func_details":{"return_type":"string","params":[]},
      "path":"/private/tmp/flow/flowlib_32caa231/core.js",
      "line":53,
      "endline":53,
      "start":5,
      "end":28
    },
    {
      "name":"toString",
      "type":"() => string",
      "func_details":{"return_type":"string","params":[]},
      "path":"/private/tmp/flow/flowlib_32caa231/core.js",
      "line":54,
      "endline":54,
      "start":5,
      "end":22
    },
    {
      "name":"valueOf",
      "type":"() => Object",
      "func_details":{"return_type":"Object","params":[]},
      "path":"/private/tmp/flow/flowlib_32caa231/core.js",
      "line":55,
      "endline":55,
      "start":5,
      "end":21
    }
  ]
}

In fact, t$est now is listed.

So there are problems with methods and properties that starts with "$" ( dollar char ). This problem arise also with the get-def command.
Instead with type-at-pos command, the method/property is recognized and the type is returned correctly.
