# gobule

Golang Go parser for the [Bule Language](https://github.com/johnowl/owl-rules).

## Usage

	"os"

	"github.com/udhos/gobule/parser"

)

func main() {

	vars := map[string]interface{}{

		"platform": "android",

	}

	envDebug := os.Getenv("DEBUG")

	debug := envDebug != ""

	log.Printf("DEBUG=[%s] debug=%v", envDebug, debug)

	result := parser.RunString("platform = 'android'", vars, debug)

	if result.IsError() {

		log.Printf("ERROR status=%d errors=%d last_error: [%s]\n", result.Status, result.Errors, result.LastError)

		return

	}

	log.Printf("result: %v", result.Eval)

}
