Functions

func CamelCase

func CamelCase(s string) string

CamelCase returns the CamelCased name. If there is an interior underscore followed by a lower case letter, drop the underscore and convert the letter to upper case. There is a remote possibility of this rewrite causing a name collision, but it's so remote we're prepared to pretend it's nonexistent - since the C++ generator lowercases names, it's extremely unlikely to have two fields with different capitalizations. In short, _my_field_name_2 becomes XMyFieldName_2.

func CamelCaseSlice

func CamelCaseSlice(elem []string) string

CamelCaseSlice is like CamelCase, but the argument is a slice of strings to be joined with "_".

func PrintComment

func PrintComment(hasEnum bool, file *ast.File)

PrintComment todo

func Rewrite

func Rewrite(g *protogen.Plugin)

Rewrite 重新文件

Types

type FieldInfo

type FieldInfo struct {
	FieldNameInProto string
	FieldNameInGo    string
	FieldTag         reflect.StructTag
	UpdateStrategy   pb.FieldTag_UpdateStrategy
}

type FileInfo

type FileInfo struct {
	FileName    string
	StructInfos []StructInfo
	HasEnum     bool
}

type Generator

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

func NewGenerator

func NewGenerator(protoFiles []FileInfo, protoGenerator *protogen.Plugin) *Generator

func (*Generator) Generate

func (g *Generator) Generate(module string)

Generate produces the rewrite content to proto's Generator.

func (*Generator) ParseGoContent

func (g *Generator) ParseGoContent(outerFile *pluginpb.CodeGeneratorResponse_File)

ParseGoContent analyzes the single package constructed from the patterns and tags. ParseGoContent exits if there is an error.

type GoFile

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

GoFile holds a single parsed astFile and associated data.

func (*GoFile) FoundProtoMessage

func (g *GoFile) FoundProtoMessage(typ string) (StructInfo, bool)

func (*GoFile) HasEnum

func (g *GoFile) HasEnum() bool

HasEnum todo

type StructInfo

type StructInfo struct {
	StructNameInProto string
	StructNameInGo    string
	FieldInfos        []FieldInfo
}

func WalkDescriptorProto

func WalkDescriptorProto(g *protogen.Plugin, dp *descriptor.DescriptorProto, typeNames []string) []StructInfo

func (*StructInfo) FindField

func (si *StructInfo) FindField(name string) (FieldInfo, bool)
