指定第一个expr接受expr的结果作为结合一个语法规则,输入12^3,识别的树为Antlr4的基本命令我们就了解到这,有兴趣研究的小伙伴,可以查看《Antlr4权威指南》这本书。第一个脚本避坑指南使用go mode模式引用antlr4默认是1.X版本,这个是低版本antlr,无法识别最新的antlr语法,使用 go get -u github.com/antlr/antlr...

expr 可以评估表达式的引擎。 gentee 可嵌入的脚本编程语言。 gisp Go中的简单LISP。 go-duktape Go的Duktape JavaScript引擎绑定。 go-lua Lua 5.2 VM到纯Go的端口。 go-php Go的PHP绑定。 go-python 与CPython C-API的幼稚go绑定。 golua Lua C API的绑定。 gopher-lua 用Go编写的Lua 5.1 VM和编译器。
