|

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.
