Closed zhangziang closed 5 years ago

zhangziang commented 5 years ago

The following code will panic

    value,err := gval.Evaluate(`a[0] + a[2]`, map[string]interface{}{
        "a":map[int]int{0:1,2:1},
    })

fixed it and added your example to the test cases

zhangziang commented 5 years ago

@generikvault If the map index‘s type is int32 or int64 or float32 … will get a err.

generikvault commented 5 years ago

@zhangziang Yes, sorry thats not supported yet. You can override the VariableSelector in your own project or extend the functionallity in gval via pull request.
