# 注意：在我编写真正的 README 之前，此 README 只是 dantecsm 的 Juice fork 的直接副本。请耐心等待。
## 用法
安装 [Racket](https://racket-lang.org/) 并运行以下命令：
```
raco exe -o juice.exe mes/juice.rkt
```
然后参考 [README](./mes/README.md)
## 说明
`--engine ADV --extraop` 的反编译规则
## 部分脚本语法摘要
branch-var
(set-var A 0)
(branch-var A
(
(/ (str "A is 0"))
(/ (str "A is 1"))
(/ (str "A is 2"))
(/ (str "A is 3"))
))
A = 0
switch (A) {
case 0:
console.log("A is 0")
break
case 1:
console.log("A is 1")
break
case 2:
console.log("A is 2")
break
case 3:
console.log("A is 3")
break
}
branch-reg
(set-reg 80 #t)
(branch-reg 80
(
(/ (str "reg 80 is false"))
(/ (str "reg 80 is true"))
)
)
reg[80] = true
if (reg[80] === false) {
console.log("reg 80 is false")
} else {
console.log("reg 80 is true")
}
if
(set-var A 1)
(set-var B 1)
(if (
(// (? (= A 1)) (str "A is 1"))
(// (? (= B 2)) (str "B is 2"))
(// (nop@) (str "A is not 1 and B is not 2"))
))
A = 1
B = 1
if (A == 1) {
console.log("A is 1")
} else if (B == 2) {
console.log("B is 2")
} else {
console.log("A is not 1 and B is not 2")
}
when
(set-var A 1)
(set-var B 1)
(proc 0)
(when (
(// (? (= A 1))
(str "A = 1") (wait) (text-reset)
)
(// (? (= A 0))
(str "A = 0") (wait) (text-reset)
)
(// (? (= B 1))
(str "B = 1") (wait) (text-reset)

A = 1
B = 1
if (A == 1) {
console.log("A = 1")
}

console.log("A = 0")
}

console.log("B = 1")
}
seg-call
`seg-call` 退出当前的 seg 块，并按顺序扫描文件中的后续 seg 块。它执行第一个条件匹配的 seg 块，然后返回到调用 seg-call 的位置继续执行。
(seg*
(str "before seg call") (wait) (text-reset)
(V = 3)
(seg-call)
(str "after seg call") (wait) (text-reset)
)
(seg (= V 2)
(str "foo") (wait) (text-reset)
)
(seg*
(str "bar") (wait) (text-reset)
)
(seg
...
)
输出：
before seg call
bar
after seg call
mes-load?
`mes-load?` 将 `.mec` 文件加载到内存并执行它。 * `(mes-load? "file path" address)` 将 .mec 文件加载到指定的内存地址。 * `(mes-load? address)` 执行先前加载到该地址的 .mec 文件。
(mes-load? "b:¥mes¥system.mec" 0)
(mes-load? 0)
(mes-load? "b:¥mes¥y_a003c.mec" 4096)
(mes-load? 4096)
