Ogma

Ogma（以这位人物的名字命名）是一个用于创建自然语言DSL的库。具体来说，该库提供便利的宏，用于将函数包装起来以解析英语参数。

示例

#[given(Add, "the addition of q`input` and d`constant` henceforth q`out`")]
fn add<'a>(
    ctx: &mut Context,
    input: &Vec<Query<'a>>,
    constant: i32,
    out: &Vec<Query<'a>>,
) -> Result<(), Trap> {
    // get global variable from `ctx` using `input`, add `constant` to it
    // and save to `ctx` via `out`
    Ok(())
}

然后您可以在脚本中使用它

   let mut ctx = bdd::Step::new();
   let script = Module::compile(
       &mut ctx,
       r#"
       Given the addition of the input and 2 henceforth the left
       And the product of the input and 2 henceforth the right
       When the left is equal to the right
       Then do nothing
       "#,
   )
   .unwrap();
   let mut instance = script.instance();
   instance.ctx_mut().set_global::<_, i32>("input", 2);
   assert!(instance.exec().is_ok());
