Go Search 已经完全用 gosl 来启动了。
相比 bash/Python 写脚本的好处:
- 纯 Go 语言,没有新的学习成本
- 引入预先导入的 package 和预定义的内置函数,方便脚本书写
- 可以无缝的和 Go 项目衔接,例如可以直接读取数据和配置。
- 和 Go 有相同的执行效率,大大快过 Python
这里贴一个简单的例子:
goslThis is an application that can make you write script with the Go language.
It is NOT an interpreter but the pure Go. The preprocessor tranforms the script into a Go program, instantly compiles and runs. So it is almost same as the standard Go with the same efficiency.
Benefit
- Pure Go language. No need to learn a new script language.
- Pre-imported packages and pre-defined functions make it easy to code.
- Seamless integration with the Go project. E.g. can easily load configuration or data file from the Go project.
- Running efficiency same as Go, much faster than Python.
Example
- Simple
