一个使用 cpp 编写的简单脚本。
构建项目：
mkdir build
cd /build
cmake ..
make\iris\build>.\main_cmake
Welcome to iris!
>>> int a = 10;
--- output ---
<- 10
>>> int b = a * 10 + (1 + 3) * (2);
--- output ---
<- 108
>>> a + b;
--- output ---
<- 118
>>> exit();
good bye!使用 -v 可以查看当前脚本的 AST
\iris\build>.\main_cmake -v
verbose mode
Welcome to iris!
>>> int a = 10 + 20;
pwc
a
+
10
20
--- output ---
<- 30
>>> a;
pwc
a
--- output ---
<- 30
