Functions

func Category

func Category() string

Category returns a const string value for rpc template category

func Clean

func Clean() error

Clean deletes all template files

func GenTemplates

func GenTemplates() error

GenTemplates is the entry for command goctl template, it will create the specified category

func ProtoTmpl

func ProtoTmpl(out string) error

ProtoTmpl returns a sample of a proto file

func RevertTemplate

func RevertTemplate(name string) error

RevertTemplate restores the deleted template files

func Update

func Update() error

Update is used to update the template files, it will delete the existing old templates at first, and then create the latest template files

Types

type Dir

type Dir struct {
	Base            string
	Filename        string
	Package         string
	GetChildPackage func(childPath string) (string, error)
}

Dir defines a directory

func (*Dir) Valid

func (d *Dir) Valid() bool

Valid returns true if the directory is valid

type DirContext

type DirContext interface {
	GetCall() Dir
	GetEtc() Dir
	GetInternal() Dir
	GetConfig() Dir
	GetLogic() Dir
	GetServer() Dir
	GetSvc() Dir
	GetPb() Dir
	GetProtoGo() Dir
	GetMain() Dir
	GetServiceName() stringx.String
	SetPbDir(pbDir, grpcDir string)
}

DirContext defines a rpc service directories context

type Generator

type Generator struct {
	// contains filtered or unexported fields
}

Generator defines the environment needs of rpc service generation

func NewGenerator

func NewGenerator(style string, verbose bool) *Generator

NewGenerator returns an instance of Generator

func (*Generator) GenCall

func (g *Generator) GenCall(ctx DirContext, proto parser.Proto, cfg *conf.Config,
	c *ZRpcContext) error

GenCall generates the rpc client code, which is the entry point for the rpc service call. It is a layer of encapsulation for the rpc client and shields the details in the pb.

func (*Generator) GenConfig

func (g *Generator) GenConfig(ctx DirContext, _ parser.Proto, cfg *conf.Config) error

GenConfig generates the configuration structure definition file of the rpc service, which contains the zrpc.RpcServerConf configuration item by default. You can specify the naming style of the target file name through config.Config. For details, see https://github.com/zeromicro/go-zero/tree/master/tools/goctl/config/config.go

func (*Generator) GenEtc

func (g *Generator) GenEtc(ctx DirContext, _ parser.Proto, cfg *conf.Config) error

GenEtc generates the yaml configuration file of the rpc service, including host, port monitoring configuration items and etcd configuration

func (*Generator) GenLogic

func (g *Generator) GenLogic(ctx DirContext, proto parser.Proto, cfg *conf.Config,
	c *ZRpcContext) error

GenLogic generates the logic file of the rpc service, which corresponds to the RPC definition items in proto.

func (*Generator) GenMain

func (g *Generator) GenMain(ctx DirContext, proto parser.Proto, cfg *conf.Config,
	c *ZRpcContext) error

GenMain generates the main file of the rpc service, which is an rpc service program call entry

func (*Generator) GenPb

func (g *Generator) GenPb(ctx DirContext, c *ZRpcContext) error

GenPb generates the pb.go file, which is a layer of packaging for protoc to generate gprc, but the commands and flags in protoc are not completely joined in goctl. At present, proto_path(-I) is introduced

func (*Generator) GenServer

func (g *Generator) GenServer(ctx DirContext, proto parser.Proto, cfg *conf.Config,
	c *ZRpcContext) error

GenServer generates rpc server file, which is an implementation of rpc server

func (*Generator) GenSvc

func (g *Generator) GenSvc(ctx DirContext, _ parser.Proto, cfg *conf.Config) error

GenSvc generates the servicecontext.go file, which is the resource dependency of a service, such as rpc dependency, model dependency, etc.

func (*Generator) Generate

func (g *Generator) Generate(zctx *ZRpcContext) error

Generate generates a rpc service, through the proto file, code storage directory, and proto import parameters to control the source file and target location of the rpc service that needs to be generated

func (*Generator) Prepare

func (g *Generator) Prepare() error

Prepare provides environment detection generated by rpc service, including go environment, protoc, whether protoc-gen-go is installed or not

type MainServiceTemplateData

type MainServiceTemplateData struct {
	Service   string
	ServerPkg string
	Pkg       string
}

type ZRpcContext

type ZRpcContext struct {
	// Sre is the source file of the proto.
	Src string
	// ProtoCmd is the command to generate proto files.
	ProtocCmd string
	// ProtoGenGrpcDir is the directory to store the generated proto files.
	ProtoGenGrpcDir string
	// ProtoGenGoDir is the directory to store the generated go files.
	ProtoGenGoDir string
	// IsGooglePlugin is the flag to indicate whether the proto file is generated by google plugin.
	IsGooglePlugin bool
	// GoOutput is the output directory of the generated go files.
	GoOutput string
	// GrpcOutput is the output directory of the generated grpc files.
	GrpcOutput string
	// Output is the output directory of the generated files.
	Output string
	// Multiple is the flag to indicate whether the proto file is generated in multiple mode.
	Multiple bool
	// Whether to generate rpc client
	IsGenClient bool
}
