Hi,
Try this fix:
expression := "beliefs['temp'] > 60 and beliefs['temp'] < 76"
env := map[string]interface{}{
`beliefs`: map[string]interface{}{
`temp`: 58.6,
},
}
- out, err := expr.Eval(expression, expr.Env(env))
+ out, err := expr.Eval(expression, env)
if err != nil {
t.Errorf("Expected no errors. Got: %v", err)
}
if out != false {
t.Errorf("Expecte `false`, got: %v", out)
}
from expr.
Also, I've added check what in future this misuse should be notified: 4d40254
from expr.
Yes... I've been working it today without the Env wrapper and it works fine. What is the point of the Env wrapper then? It creates a type table of some sort?
from expr.
Yes, expr.Env
creates type tables for type checker. Take a look at this example: https://godoc.org/github.com/antonmedv/expr#example-Compile
Compile ahead of time will allow faster execution and type checking of expression before going to production.
