Thanks Adam.
This how my code looks like
* fun decodeProto(protoFile: VirtualFile) { try { val fileDescriptorSet =
generateFileDescriptorSet(protoFile) val fileDescriptor:
Descriptors.FileDescriptor = parseFileDescriptorSet(fileDescriptorSet) val
dynamicMessage:DynamicMessage =
DynamicMessage.parseFrom(fileDescriptor.messageTypes[0],pbFile.inputStream.readBytes())
println(TextFormat.printToString(dynamicMessage)) }catch (ex:Exception){
ex.printStackTrace() } } private fun generateFileDescriptorSet(protoFile:
VirtualFile): ByteArray { val protocCommand = "protoc
-I=${protoFile.parent} --include_imports --descriptor_set_out=/dev/stdout
${protoFile.path}" val outputStream = ByteArrayOutputStream() val process =
Runtime.getRuntime().exec(protocCommand)
process.inputStream.copyTo(outputStream) process.waitFor() return
outputStream.toByteArray() } private fun
parseFileDescriptorSet(fileDescriptorSetBytes: ByteArray):
Descriptors.FileDescriptor { val fileDescriptorSet =
DescriptorProtos.FileDescriptorSet.parseFrom(fileDescriptorSetBytes) val
fileDescriptors = fileDescriptorSet.fileList.map {
Descriptors.FileDescriptor.buildFrom(it,
arrayOf<Descriptors.FileDescriptor>()) }.toTypedArray() return
Descriptors.FileDescriptor.buildFrom( fileDescriptorSet.fileList.first(),
fileDescriptors ) }*
I was wondering if there is an existing api, which will convert the
*DynamicMessage
*to json.
Also, in other thread you mentioned, it's better to use *cd *to fix import
issues,
probably do cd here *val protocCommand = "protoc -I=${protoFile.parent}
--include_imports --descriptor_set_out=/dev/stdout ${protoFile.path}" *and
then run the command.
Thanks a lot!
