Unable to call object properties that are functions

[mhagmajer]

The following code produces a parsing error when run on the playground

ask {
  const sum = fun(a, b) {
      a + b
  }
  
  const diff = fun(a, b) {
      a - b
  }
  
  const myMath = { sum, diff }
   
  myMath.sum(2, 2)
}

It works fine, when myMath is destructured first:

const s = myMath.sum
s(2,2)

Used expression (myMath.sum(2, 2)) should be translated into

<call
  args={
    <list>
      {2}
      {2}
    </list>
  }
>
  <call
    name="at"
    args={
      <list>
        <ref name="myMath" />
        {"sum"}
      </list>
    }
  />
</call>

Note that call in AskJSX can accept either the name property in args or function expression in its first child.

yesterday, while digging into the parser I had an idea that maybe we just change how . works:

askql/src/askscript/parser/askscript.grammar.pegjs

Line 237 in fea7233

/ ws* '.' ws* i:identifier { return new ask.KeyIdentifierApplied(i) }

- somehow making it more like the : I mean adding an option for a MethodCallApplied transformation instead of KeyExpressionApplied

That's why it works by deconstruction - bc. when deconstructed it gets into:

askql/src/askscript/parser/askscript.grammar.pegjs

Line 234 in fea7233

functionCall = i:identifier ws* '(' cAL:callArgList ')' { return new ask.FunctionCall(i, cAL) }
