目前已经集成的工具有：
* `protoc`用于快速生成`*.pb.go`和`*.bm.go`文件，但目前不支持windows，Linux也需要先自己安装`protoc`工具。
* `swagger`用于显示自动生成的BM API接口文档，通过 `kratos tool swagger serve api/api.swagger.json` 可以访问到文档。
* TODOs...
* kratos 为本体工具，只用于安装更新使用；
* protoc 用于快速生成gRPC、HTTP、Swagger文件，该命令Windows，Linux用户需要手动安装 protobuf 工具。
* swagger 用于显示自动生成的HTTP API接口文档，通过 `kratos tool swagger serve api/api.swagger.json` 可以查看文档。
### kratos tool protoc
该命令运行没其他参数，直接`kratos tool protoc`运行即可。但使用前需特别说明：
```
// generate all
kratos tool protoc api.proto
// generate gRPC
kratos tool protoc --grpc api.proto
// generate BM HTTP
kratos tool protoc --bm api.proto
// generate swagger
kratos tool protoc --swagger api.proto
```
执行对应生成 `api.pb.go/api.bm.go/api.swagger.json` 源文档。
* 该工具在Windows/Linux下运行，需提前安装好`protoc`工具
> 该工具在Windows/Linux下运行，需提前安装好 protobuf 工具
该工具实际是一段`shell`脚本，其中自动将`protoc`命令进行了拼接，识别了需要`*.proto`的目录和当前目录下的`proto`文件，最终会拼接为如下命令进行执行：

大家也可以参考该命令进行`proto`生成`*.pb.go`和`*.bm.go`文件，也可以参考[protoc说明](protoc.md)。
大家也可以参考该命令进行`proto`生成，也可以参考[protobuf](https://github.com/google/protobuf)官方参数。

kratos new kratos-demo -o Tinker --proto

kratos tool swagger serve kratos-demo/api/api.swagger.json

执行命令后，浏览器会自动打开swagger文档地址。
同时也可以查看更多的 [go-swagger](https://github.com/go-swagger/go-swagger) 官方参数进行使用。

请注意替换`/Users/felix/work/go/src`目录为你本地开发环境对应GOPATH目录，其中`--gogofast_out`意味着告诉`protoc`工具需要使用`gogo protobuf`的工具生成代码。
