生成跨语言的类型声明和接口绑定的工具（Djinni ）

Djinni 是一个用来生成跨语言的类型声明和接口绑定的工具，主要用于 C++ 和 Java 以及 Objective-C 间的互通。

示例接口定义文件：

# Multi-line comments can be added here. This comment will be propagated
# to each generated definition.
my_enum = enum {
    option1;
    option2;
    option3;
}
 
my_record = record {
    id: i32;
    info: string;
    store: set<string>;
    hash: map<string, i32>;
 
    values: list<another_record>;
 
    # Comments can also be put here
 
    # Constants can be included
    const string_const: string = "Constants can be put here";
    const min_value: another_record = {
        key1 = 0,
        key2 = ""
    };
}
 
another_record = record {
    key1: i32;
    key2: string;
} deriving (eq, ord)
 
# This interface will be implemented in C++ and can be called from any language.
my_cpp_interface = interface +c {
    method_returning_nothing(value: i32);
    method_returning_some_type(key: string): another_record;
    static get_version(): i32;
 
    # Interfaces can also have constants
    const version: i32 = 1;
}
 
# This interface will be implemented in Java and ObjC and can be called from C++.
my_client_interface = interface +j +o {
    log_string(str: string): bool;
}

使用方法：

@import "relative/path/to/filename.djinni"
