==============================
Small library on top of reflect for make lookups to Structs or Maps. Using a very simple DSL you can access to any property, key or value of any value of Go.
Installation
------------
The recommended way to install go-lookup
```
go get github.com/mcuadros/go-lookup
```
Example
-------
```go
type Cast struct {
Actor, Role string
}
type Serie struct {
Cast []Cast
}
series := map[string]Serie{
"A-Team": {Cast: []Cast{
{Actor: "George Peppard", Role: "Hannibal"},
{Actor: "Dwight Schultz", Role: "Murdock"},
{Actor: "Mr. T", Role: "Baracus"},
{Actor: "Dirk Benedict", Role: "Faceman"},
}},
}
q := "A-Team.Cast.Role"
value, _ := LookupString(series, q)
fmt.Println(q, "->", value.Interface())
// A-Team.Cast.Role -> [Hannibal Murdock Baracus Faceman]
q = "A-Team.Cast[0].Actor"
value, _ = LookupString(series, q)
fmt.Println(q, "->", value.Interface())
// A-Team.Cast[0].Actor -> George Peppard
