go-script

使用golang一些类型进行类似scheme语法的脚本编程

usage

package main

import (
  "fmt"

  go_script "github.com/pysta3515/go-script"
)

type Sale struct {
  SaleID    int64
  SalePrice float64
  Shop      *Shop
}

func (sale *Sale) Env() map[string]interface{} {
  return go_script.Env(sale, "sale")
}

type Shop struct {
  ShopID int
}

func main() {
  id := 10
  env := go_script.Env(id, "id")
  e := "(+  (- id 1) 2 (+ 3 4))"
  fmt.Println(go_script.Eval(e).ToInt(env))
  sale := Sale{
    1,
    2.2,
    &Shop{
      3,
    },
  }
  e = "(if (>= sale.SaleID 1) 10.1 0)"
  fmt.Println(go_script.Eval(e).ToFloat(sale.Env()))
}
