This is a small script language, and helps beginners to learn compilation principles.

It is called Gscript because it is written with Go.

Installation

go get github.com/crossoverJie/gscript

gscript -h

Or download the binary file directly

Features

• Basic quadratic operations
• More basic type
• Support scope and function
• Support closure
• OOP
