An error is also caused if a field with a default value is used in a message:

The description (experimental) plugin generates a Description method for each message.
The Description method returns a populated google_protobuf.FileDescriptorSet struct.
This contains the description of the files used to generate this message.
It is enabled by the following extensions:
- description
- description_all
The description plugin also generates a test given it is enabled using one of the following extensions:
- testgen
- testgen_all
Let us look at:
github.com/gogo/protobuf/test/example/example.proto
Btw all the output can be seen at:
github.com/gogo/protobuf/test/example/*
The following message:
message B {
option (gogoproto.description) = true;
optional A A = 1 [(gogoproto.nullable) = false, (gogoproto.embed) = true];
repeated bytes G = 2 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uint128", (gogoproto.nullable) = false];
}
given to the description plugin, will generate the following code:
func (this *B) Description() (desc *google_protobuf.FileDescriptorSet) {
return ExampleDescription()
}
and the following test code:
func TestDescription(t *testing9.T) {
ExampleDescription()
}
The hope is to use this struct in some way instead of reflect.
This package is subject to change, since a use has not been figured out yet.

The equal plugin generates an Equal and a VerboseEqual method for each message.
These equal methods are quite obvious.
The only difference is that VerboseEqual returns a non nil error if it is not equal.
This error contains more detail on exactly which part of the message was not equal to the other message.
The idea is that this is useful for debugging.
Equal is enabled using the following extensions:
- equal
- equal_all
While VerboseEqual is enable dusing the following extensions:
- verbose_equal
- verbose_equal_all
The equal plugin also generates a test given it is enabled using one of the following extensions:
- testgen
- testgen_all
Let us look at:
github.com/gogo/protobuf/test/example/example.proto
Btw all the output can be seen at:
github.com/gogo/protobuf/test/example/*
The following message:
option (gogoproto.equal_all) = true;
option (gogoproto.verbose_equal_all) = true;
message B {
optional A A = 1 [(gogoproto.nullable) = false, (gogoproto.embed) = true];
repeated bytes G = 2 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uint128", (gogoproto.nullable) = false];
}
given to the equal plugin, will generate the following code:
func (this *B) VerboseEqual(that interface{}) error {
if that == nil {
if this == nil {
return nil
}
return fmt2.Errorf("that == nil && this != nil")

}

}
if len(this.G) != len(that1.G) {

}
for i := range this.G {

}
}
if !bytes.Equal(this.XXX_unrecognized, that1.XXX_unrecognized) {

/*
The face plugin generates a function will be generated which can convert a structure which satisfies an interface (face) to the specified structure.
This interface contains getters for each of the fields in the struct.
The specified struct is also generated with the getters.
This means that getters should be turned off so as not to conflict with face getters.
This allows it to satisfy its own face.
It is enabled by the following extensions:
- face
- face_all
Turn off getters by using the following extensions:
- getters
- getters_all
The face plugin also generates a test given it is enabled using one of the following extensions:
- testgen
- testgen_all
Let us look at:
github.com/gogo/protobuf/test/example/example.proto
Btw all the output can be seen at:
github.com/gogo/protobuf/test/example/*
The following message:
message A {
option (gogoproto.face) = true;
option (gogoproto.goproto_getters) = false;
optional string Description = 1 [(gogoproto.nullable) = false];
optional int64 Number = 2 [(gogoproto.nullable) = false];
optional bytes Id = 3 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uuid", (gogoproto.nullable) = false];
}
given to the face plugin, will generate the following code:
type AFace interface {
Proto() github_com_gogo_protobuf_proto.Message
GetDescription() string
GetNumber() int64
GetId() github_com_gogo_protobuf_test_custom.Uuid
}
func (this *A) Proto() github_com_gogo_protobuf_proto.Message {
return this
}
func (this *A) TestProto() github_com_gogo_protobuf_proto.Message {
return NewAFromFace(this)
}
func (this *A) GetDescription() string {
return this.Description
}
func (this *A) GetNumber() int64 {
return this.Number
}
func (this *A) GetId() github_com_gogo_protobuf_test_custom.Uuid {
return this.Id
}
func NewAFromFace(that AFace) *A {
this := &A{}
this.Description = that.GetDescription()
this.Number = that.GetNumber()
this.Id = that.GetId()
return this
}
and the following test code:
func TestAFace(t *testing7.T) {
popr := math_rand7.New(math_rand7.NewSource(time7.Now().UnixNano()))
p := NewPopulatedA(popr, true)
msg := p.TestProto()
if !p.Equal(msg) {
t.Fatalf("%#v !Face Equal %#v", msg, p)
}
}
The struct A, representing the message, will also be generated just like always.
As you can see A satisfies its own Face, AFace.
Creating another struct which satisfies AFace is very easy.
Simply create all these methods specified in AFace.
Implementing The Proto method is done with the helper function NewAFromFace:
func (this *MyStruct) Proto() proto.Message {
return NewAFromFace(this)
}
just the like TestProto method which is used to test the NewAFromFace function.

/*
The gostring plugin generates a GoString method for each message.
The GoString method is called whenever you use a fmt.Printf as such:
fmt.Printf("%#v", mymessage)
or whenever you actually call GoString()
The output produced by the GoString method can be copied from the output into code and used to set a variable.
It is totally valid Go Code and is populated exactly as the struct that was printed out.
It is enabled by the following extensions:
- gostring
- gostring_all
The gostring plugin also generates a test given it is enabled using one of the following extensions:
- testgen
- testgen_all
Let us look at:
github.com/gogo/protobuf/test/example/example.proto
Btw all the output can be seen at:
github.com/gogo/protobuf/test/example/*
The following message:
option (gogoproto.gostring_all) = true;
message A {
optional string Description = 1 [(gogoproto.nullable) = false];
optional int64 Number = 2 [(gogoproto.nullable) = false];
optional bytes Id = 3 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uuid", (gogoproto.nullable) = false];
}
given to the gostring plugin, will generate the following code:
func (this *A) GoString() string {
if this == nil {
return "nil"
}
s := strings1.Join([]string{`&test.A{` + `Description:` + fmt1.Sprintf("%#v", this.Description), `Number:` + fmt1.Sprintf("%#v", this.Number), `Id:` + fmt1.Sprintf("%#v", this.Id), `XXX_unrecognized:` + fmt1.Sprintf("%#v", this.XXX_unrecognized) + `}`}, ", ")
return s
}
and the following test code:
func TestAGoString(t *testing6.T) {
popr := math_rand6.New(math_rand6.NewSource(time6.Now().UnixNano()))
p := NewPopulatedA(popr, false)
s1 := p.GoString()
s2 := fmt2.Sprintf("%#v", p)
if s1 != s2 {
t.Fatalf("GoString want %v got %v", s1, s2)
}
_, err := go_parser.ParseExpr(s1)
if err != nil {
panic(err)
}
}
Typically fmt.Printf("%#v") will stop to print when it reaches a pointer and
not print their values, while the generated GoString method will always print all values, recursively.

/*
The populate plugin generates a NewPopulated function.
This function returns a newly populated structure.
It is enabled by the following extensions:
- populate
- populate_all
Let us look at:
github.com/gogo/protobuf/test/example/example.proto
Btw all the output can be seen at:
github.com/gogo/protobuf/test/example/*
The following message:
option (gogoproto.populate_all) = true;
message B {
optional A A = 1 [(gogoproto.nullable) = false, (gogoproto.embed) = true];
repeated bytes G = 2 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uint128", (gogoproto.nullable) = false];
}
given to the populate plugin, will generate code the following code:
func NewPopulatedB(r randyExample, easy bool) *B {
this := &B{}
v2 := NewPopulatedA(r, easy)
this.A = *v2
if r.Intn(10) != 0 {
v3 := r.Intn(10)
this.G = make([]github_com_gogo_protobuf_test_custom.Uint128, v3)
for i := 0; i < v3; i++ {
v4 := github_com_gogo_protobuf_test_custom.NewPopulatedUint128(r)
this.G[i] = *v4
}
}
if !easy && r.Intn(10) != 0 {
this.XXX_unrecognized = randUnrecognizedExample(r, 3)
}
return this
}
The idea that is useful for testing.
Most of the other plugins' generated test code uses it.
You will still be able to use the generated test code of other packages
if you turn off the popluate plugin and write your own custom NewPopulated function.
If the easy flag is not set the XXX_unrecognized and XXX_extensions fields are also populated.
These have caused problems with JSON marshalling and unmarshalling tests.

The size plugin generates a Size or ProtoSize method for each message.
This is useful with the MarshalTo method generated by the marshalto plugin and the
gogoproto.marshaler and gogoproto.marshaler_all extensions.
It is enabled by the following extensions:
- sizer
- sizer_all
- protosizer
- protosizer_all
The size plugin also generates a test given it is enabled using one of the following extensions:
- testgen
- testgen_all
And a benchmark given it is enabled using one of the following extensions:
- benchgen
- benchgen_all
Let us look at:
github.com/gogo/protobuf/test/example/example.proto
Btw all the output can be seen at:
github.com/gogo/protobuf/test/example/*
The following message:
option (gogoproto.sizer_all) = true;
message B {
option (gogoproto.description) = true;
optional A A = 1 [(gogoproto.nullable) = false, (gogoproto.embed) = true];
repeated bytes G = 2 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uint128", (gogoproto.nullable) = false];
}
given to the size plugin, will generate the following code:
func (m *B) Size() (n int) {
if m == nil {
return 0
}
var l int
_ = l
l = m.A.Size()
n += 1 + l + sovExample(uint64(l))
if len(m.G) > 0 {
for _, e := range m.G {
l = e.Size()
n += 1 + l + sovExample(uint64(l))
}
}
if m.XXX_unrecognized != nil {
n += len(m.XXX_unrecognized)
}
return n
}
and the following test code:
func TestBSize(t *testing5.T) {
popr := math_rand5.New(math_rand5.NewSource(time5.Now().UnixNano()))
p := NewPopulatedB(popr, true)
dAtA, err := github_com_gogo_protobuf_proto2.Marshal(p)
if err != nil {
panic(err)
}
size := p.Size()
if len(dAtA) != size {
t.Fatalf("size %v != marshalled size %v", size, len(dAtA))
}
}
func BenchmarkBSize(b *testing5.B) {
popr := math_rand5.New(math_rand5.NewSource(616))
total := 0
pops := make([]*B, 1000)
for i := 0; i < 1000; i++ {
pops[i] = NewPopulatedB(popr, false)
}
b.ResetTimer()
for i := 0; i < b.N; i++ {
total += pops[i%1000].Size()
}
b.SetBytes(int64(total / b.N))
}
The sovExample function is a size of varint function for the example.pb.go file.

/*
The stringer plugin generates a String method for each message.
It is enabled by the following extensions:
- stringer
- stringer_all
The stringer plugin also generates a test given it is enabled using one of the following extensions:
- testgen
- testgen_all
Let us look at:
github.com/gogo/protobuf/test/example/example.proto
Btw all the output can be seen at:
github.com/gogo/protobuf/test/example/*
The following message:
option (gogoproto.goproto_stringer_all) = false;
option (gogoproto.stringer_all) = true;
message A {
optional string Description = 1 [(gogoproto.nullable) = false];
optional int64 Number = 2 [(gogoproto.nullable) = false];
optional bytes Id = 3 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uuid", (gogoproto.nullable) = false];
}
given to the stringer stringer, will generate the following code:
func (this *A) String() string {
if this == nil {
return "nil"
}
s := strings.Join([]string{`&A{`,
`Description:` + fmt.Sprintf("%v", this.Description) + `,`,
`Number:` + fmt.Sprintf("%v", this.Number) + `,`,
`Id:` + fmt.Sprintf("%v", this.Id) + `,`,
`XXX_unrecognized:` + fmt.Sprintf("%v", this.XXX_unrecognized) + `,`,
`}`,
}, "")
return s
}
and the following test code:
func TestAStringer(t *testing4.T) {
popr := math_rand4.New(math_rand4.NewSource(time4.Now().UnixNano()))
p := NewPopulatedA(popr, false)
s1 := p.String()
s2 := fmt1.Sprintf("%v", p)
if s1 != s2 {
t.Fatalf("String want %v got %v", s1, s2)
}
}
Typically fmt.Printf("%v") will stop to print when it reaches a pointer and
not print their values, while the generated String method will always print all values, recursively.

The testgen plugin generates Test and Benchmark functions for each message.
Tests are enabled using the following extensions:
- testgen
- testgen_all
Benchmarks are enabled using the following extensions:
- benchgen
- benchgen_all
Let us look at:

optional int64 Number = 2 [(gogoproto.nullable) = false];
optional bytes Id = 3 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uuid", (gogoproto.nullable) = false];

Other registered tests are also generated.
Tests are registered to this test plugin by calling the following function.
func RegisterTestPlugin(newFunc NewTestPlugin)
where NewTestPlugin is:
type NewTestPlugin func(g *generator.Generator) TestPlugin
and TestPlugin is an interface:
type TestPlugin interface {
Generate(imports generator.PluginImports, file *generator.FileDescriptor) (used bool)
}
Plugins that use this interface include:
- populate
- gostring
- equal
- union
- and more
Please look at these plugins as examples of how to create your own.
A good idea is to let each plugin generate its own tests.

/*
The onlyone plugin generates code for the onlyone extension.
All fields must be nullable and only one of the fields may be set, like a union.
Two methods are generated
GetValue() interface{}
and
SetValue(v interface{}) (set bool)
These provide easier interaction with a onlyone.
The onlyone extension is not called union as this causes compile errors in the C++ generated code.
There can only be one ;)
It is enabled by the following extensions:
- onlyone
- onlyone_all
The onlyone plugin also generates a test given it is enabled using one of the following extensions:
- testgen
- testgen_all
Lets look at:
github.com/gogo/protobuf/test/example/example.proto
Btw all the output can be seen at:
github.com/gogo/protobuf/test/example/*
The following message:
message U {
option (gogoproto.onlyone) = true;
optional A A = 1;
optional B B = 2;
}
given to the onlyone plugin, will generate code which looks a lot like this:
func (this *U) GetValue() interface{} {
if this.A != nil {
return this.A
}
if this.B != nil {
return this.B
}
return nil
}
func (this *U) SetValue(value interface{}) bool {
switch vt := value.(type) {
case *A:
this.A = vt
case *B:
this.B = vt
default:
return false
}
return true
}
and the following test code:
func TestUUnion(t *testing.T) {
popr := math_rand.New(math_rand.NewSource(time.Now().UnixNano()))
p := NewPopulatedU(popr)
v := p.GetValue()
msg := &U{}
if !msg.SetValue(v) {
t.Fatalf("Union: Could not set Value")
}
if !p.Equal(msg) {
t.Fatalf("%#v !Union Equal %#v", msg, p)
}
}

/*
A plugin for the Google protocol buffer compiler to generate Go code.
Run it by building this program and putting it in your path with the name
protoc-gen-gogo
That word 'gogo' at the end becomes part of the option string set for the
protocol compiler, so once the protocol compiler (protoc) is installed
you can run
protoc --gogo_out=output_directory input_directory/file.proto
to generate Go bindings for the protocol defined by file.proto.
With that input, the output will be written to
output_directory/go_package/file.pb.go
The generated code is documented in the package comment for
the library.
See the README and documentation for protocol buffers to learn more:
https://developers.google.com/protocol-buffers/

// files need not reside completely in memory at one time. Note that as of
// this writing protoc does not optimize for this -- it will read the entire
// CodeGeneratorResponse before writing files to disk.
Name *string `protobuf:"bytes,1,opt,name=name" json:"name,omitempty"`
// If non-empty, indicates that the named file should already exist, and the
// content here is to be inserted into that file at a defined insertion
// point. This feature allows a code generator to extend the output
// produced by another code generator. The original generator may provide
// insertion points by placing special annotations in the file that look
// like:
// @@protoc_insertion_point(NAME)
// The annotation can have arbitrary text before and after it on the line,
// which allows it to be placed in a comment. NAME should be replaced with
// an identifier naming the point -- this is what other generators will use
// as the insertion_point. Code inserted at this point will be placed
// immediately above the line containing the insertion point (thus multiple
// insertions to the same point will come out in the order they were added).
// The double-@ is intended to make it unlikely that the generated code
// could contain things that look like insertion points by accident.
//
// For example, the C++ code generator places the following line in the
// .pb.h files that it generates:
// // @@protoc_insertion_point(namespace_scope)
// This line appears within the scope of the file's package namespace, but
// outside of any particular class. Another plugin can then specify the
// insertion_point "namespace_scope" to generate additional classes or
// other declarations that should be placed in this scope.
//
// Note that if the line containing the insertion point begins with
// whitespace, the same whitespace will be added to every line of the
// inserted text. This is useful for languages like Python, where
// indentation matters. In these languages, the insertion point comment
// should be indented the same amount as any inserted code will need to be
// in order to work correctly in that context.
//
// The code generator that generates the initial file and the one which
// inserts into it must both run as part of a single invocation of protoc.
// Code generators are executed in the order in which they appear on the
// command line.
//
// If |insertion_point| is present, |name| must also be present.

Name *string `protobuf:"bytes,1,opt,name=name" json:"name,omitempty"`
// If non-empty, indicates that the named file should already exist, and the
// content here is to be inserted into that file at a defined insertion
// point. This feature allows a code generator to extend the output
// produced by another code generator. The original generator may provide
// insertion points by placing special annotations in the file that look
// like:
// @@protoc_insertion_point(NAME)
// The annotation can have arbitrary text before and after it on the line,
// which allows it to be placed in a comment. NAME should be replaced with
// an identifier naming the point -- this is what other generators will use
// as the insertion_point. Code inserted at this point will be placed
// immediately above the line containing the insertion point (thus multiple
// insertions to the same point will come out in the order they were added).
// The double-@ is intended to make it unlikely that the generated code
// could contain things that look like insertion points by accident.
//
// For example, the C++ code generator places the following line in the
// .pb.h files that it generates:
// // @@protoc_insertion_point(namespace_scope)
// This line appears within the scope of the file's package namespace, but
// outside of any particular class. Another plugin can then specify the
// insertion_point "namespace_scope" to generate additional classes or
// other declarations that should be placed in this scope.
//
// Note that if the line containing the insertion point begins with
// whitespace, the same whitespace will be added to every line of the
// inserted text. This is useful for languages like Python, where
// indentation matters. In these languages, the insertion point comment
// should be indented the same amount as any inserted code will need to be
// in order to work correctly in that context.
//
// The code generator that generates the initial file and the one which
// inserts into it must both run as part of a single invocation of protoc.
// Code generators are executed in the order in which they appear on the
// command line.
//
