Example

type Type byte

const (
	TypeCA Type = iota
	TypeCB
	NotTypeCA = 2
	NotTypeCB = iota
	TypeCC    = Type(iota)
	TypeCD
	NotTypeCC      = int(iota)
	NotTypeCD      = byte(7)
	TypeCE    Type = 8
	TypeCF    Type = 9
)

FindStructByName

FindStructByName find struct in *ast.File

Parameter
StructName: try to find the struct name

Return
*ast.TypeSpec  : struct declaration
*ast.StructType: struct content declaration
bool           : is found struct

Example

func F() {}
FindStructByName(f,"F")

Function

FindFuncByName

FindFuncByName(f *ast.File, ReceiverType, FuncName string) (*ast.FuncDecl, bool)

Parameter
ReceiverType : method pass the receiver type if there is a receiver or empty string
FuncName     : try to find the function name


Return
*ast.FuncDecl : return the found the function or nil
bool          : return true if found function or false

Example Function Without Receiver

func F() {}
func FindFuncByName(f,"","F")

Example Function With Receiver

type idea struct{}
func (idea) F(){}
func (*idea) F(){}
func (i idea) F(){}
func (i *idea) F(){}
func FindFuncByName(f,"idea","F")
