今天是最后一天了，如果没大进步就算了

毕竟我还有更有用的东西要做，而且我现在的水平的确还有待提升

还有包没下好，100M 左右呢... 估计是过几天的事了，先干别的，到时候看 decompiler 结果怎么样

retdec 看感觉反编译结果特别好看，几乎都能直接拿去重新编译了

想给 Lite 写个 LV（Lite VM）
或者给 Java 创建 bc 的绑定（binding）
或者 Wren...

接下来总结 Lite 的功能，准备写 LV 🌚

10 views13:17

duangsues.is_a? SaltedFish

- LV 要成为 stack-based machine
- LV 要拥有一个 call-stack 和一个 stack 和一个 global table，gtable 必须是线程安全的
- LV 使用词法作用域和 lazy-init 优化（不是替换绑定）
- LV 要能支持 block
- LV 要能实现 Lite 的所有功能
- LV 要支持这些字面量：
- true / false
- null
- number ( byte, short, int, long, float, double, BigInteger, BigDecimal )
- string / char
- symbol
- range

- 要能创建一定维度的数组
- [] 能索引数组、Map、List、Object（getXXXX property or field）、subclass、static member
- []= 能新建索引数组、Map、List、Object（setXXXX property or field）、static member
- :: 是快速版本的 [] （语法糖），在虚拟机层面上不存在的
- -> 能修改数组、Map、List、Object（setXXXX property or field）、static member（语法糖）

- 块内 return、break、next

- LV 要支持行注释：

- LV 要能进行动态链接
- LV 要支持调试信息（文件名、行号）

- LV 暂时只使用代码文本表示
- LV 支持指令插件

- Lite 支持这些东西：
- vararg(在虚拟机层面不存在)
- block
- while、if、for、def、call、assign、
- | or in & and < > <= >= != == !== === << to + - * / % ** :: as
- unary - ! ++ —
-
