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：

 1 # Multi-line comments can be added here. This comment will be propagated
 2 # to each generated definition.
 3 my_enum = enum {
 4     option1;
 5     option2;
 6     option3;
 7 }
 8
 9 my_record = record {
10     id: i32;
11     info: string;
12     store: set<string>;
13     hash: map<string, i32>;
14
15     values: list<another_record>;
16
17     # Comments can also be put here
18
19     # Constants can be included
20     const string_const: string = "Constants can be put here";
21     const min_value: another_record = {
22         key1 = 0,
23         key2 = ""
24     };
25 }
26
27 another_record = record {
28     key1: i32;
29     key2: string;
30 } deriving (eq, ord)
31
32 # This interface will be implemented in C++ and can be called from any language.
33 my_cpp_interface = interface +c {
34     method_returning_nothing(value: i32);
35     method_returning_some_type(key: string): another_record;
36     static get_version(): i32;
37
38     # Interfaces can also have constants
39     const version: i32 = 1;
40 }
41
42 # This interface will be implemented in Java and ObjC and can be called from C++.
43 my_client_interface = interface +j +o {
44     log_string(str: string): bool;
45 }

使用方法：

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