Unable to define and look up array

[preciselytom]

According to the readme, you can define an array in gval:

Json Arrays : [1, 2, "foo"]

And you can look up an element from an array:

Map and array elements and Struct Field can be accessed via [].
foo[0]

Then I should be able to define an array and look up an element:

[10,11,12,13][2]

I expected this to return 12, but instead I got:

&errors.errorString{s:"parsing error: [10,11,12,13][2]\t:1:14 - 1:15 unexpected \"[\" while scanning operator"}

What I'm trying to do is let a customer define an array in a gval string, and input from their user will be used to look up an element:

["foo", "bar", ...][x]

Where "foo", "bar", ... is written by an admin, and x comes from an end user.

Yes the VariableSelector is currently fixed tied to variables. That is the reason why [10,11,12,13][2] can't be parsed.

The VariableSelector could instead be implemented as a PostfixOperator.

Makes sense. I would appreciate a fix for this. 🙂

I can do this but it will take some time.
