Provides support for evaluating string expressions.

How to use it?

---

You need to have 3 arguments to evaluate your expression.

• The string expression that defines the actual values and comparators against which the evaluation will happen platform=='android'&&version>='10.9.8'&&segment==89
• The map of interface that defines the expression variables that you want to evaluate

   {
      "platform": "android",
      "version": "12.3.4",
      "segment": 98
   }
  

  • The final part is a list of Variable struct which defines the type of the variable in the expression.

    • variable1 := Variable{
         Name:  "appVersion",
         Type:  Version,
         Value: "10.9.7",
       }
      variable2 := Variable{
         Name:  "platform",
         Type:  String,
         Value: "android",
       }
      var variables []Variable
      
      variables = append(variables, variable1)
      variables = append(variables, variable2)
      

We will use all this to call the EvaluateExpression which returns a *bool and error

variable1 := Variable{
    Name:  "appVersion",
    Type:  Version,
    Value: "10.9.7",
}
variable2 := Variable{
    Name:  "platform",
    Type:  String,
    Value: "android",
}
variable3 := Variable{
    Name:  "segment",
    Type:  Number,
    Value: 98,
}

var variables []Variable

variables = append(variables, variable1)
variables = append(variables, variable2)
request := map[string]interface{}{
    "appVersion": "10.9.8",
}

result, err := EvaluateExpression("appVersion>='10.9.8'&&segment==98&&platform=='android'", request, variables)
