Structs

Rule :

type Rule struct {
	Output 			string   `json:"output"`
	Input  			[]string `json:"input"`
	Expression   	string   `json:"expression"`
	...
}

Engine:

type Engine struct {
    Facts         map[string]interface{}
	Rules         []Rule
	RuleFunctions map[string]govaluate.ExpressionFunction
	Jobs          chan int
    ...
}

Example

Please see in test file especially TestRun() function.

package main

import "github.com/jonathansudibya/fished"

func main() {
	e := fished.New(nil)
	e.SetRules([]Rule{
		Rule{
			Input: []string{"hello"},
			Output: "result_end",
			Expression: "hello == 'world'",
		}
	})
	e.SetFacts = map[string]interface{}{
		"hello": "world"
	}
	res, errs := e.Run()

	fmt.Println(res) // will result true
}

Notes

Remember it is more expensive to set new rules than to set facts.
