gen-go-enum
A tool for generate hessian2 java enum define golang code.
go build -o gen-go-enum tools/gen-go-enum/main.go
For example, run command gen-go-enum -c com.test.enums.TestColorEnum -v RED -v BLUE -v YELLOW
will create a golang code file like this.
package enum
import (
"strconv"
)
import (
hessian "gitee.com/wenj91/dubbo-go-hessian2"
)
const (
TestColorEnumRed TestColorEnum = iota
TestColorEnumBlue
TestColorEnumYellow
)
var _TestColorEnumValues = map[TestColorEnum]string{
TestColorEnumRed: "RED",
TestColorEnumBlue: "BLUE",
TestColorEnumYellow: "YELLOW",
}
var _TestColorEnumEntities = map[string]TestColorEnum{
"RED": TestColorEnumRed,
"BLUE": TestColorEnumBlue,
"YELLOW": TestColorEnumYellow,
}
type TestColorEnum hessian.JavaEnum
func (e TestColorEnum) JavaClassName() string {
return "com.test.enums.TestColorEnum"
}
func (e TestColorEnum) String() string {
if v, ok := _TestColorEnumValues[e]; ok {
return v
}
return strconv.Itoa(int(e))
}
func (e TestColorEnum) EnumValue(s string) hessian.JavaEnum {
if v, ok := _TestColorEnumEntities[s]; ok {
return hessian.JavaEnum(v)
}
return hessian.InvalidJavaEnum
}
func NewTestColorEnum(s string) TestColorEnum {
if v, ok := _TestColorEnumEntities[s]; ok {
return v
}
return TestColorEnum(hessian.InvalidJavaEnum)
}
func init() {
for v := range _TestColorEnumValues {
hessian.RegisterJavaEnum(v)
}
}
You can specify more options, like the usage.
gen-go-enum can generate golang code for hessian2 java enum.
Usage: gen-go-enum -c java_classname [-p golang_package_name] [-e golang_enum_name] -v java_enum_value [-v java_enum_value] [-o target_file]
Options
-c java class name (eg: com.test.enums.TestEnum)
-p golang package name, use 'enum' when not specified (eg: test_enum)
-e golang enum type name, use java class name when not specified (eg: TestEnum)
-v java enum values, can specify multiple (eg: -v TEST1 -v TEST2 -v TEST3)
-o golang code file path, stored in the current directory when not specified
Example
gen-go-enum -c com.test.enums.TestColorEnum -v RED -v BLUE -v YELLOW
gen-go-enum -c com.test.enums.TestColorEnum -p test_enums -e ColorEnum -v RED -v BLUE -v YELLOW -o ./color_enum.go
