Proctoc-gen-arkts

Compile .proto files to plain arkTs.

Contributing

• the future is open to everyone

Features

• Supports json encoding (toJson, fromJson)
• Supports binary encoding (toBinary, fromBinary)

Usage

Protoc

protoc -I $proto_path --arkts_out=$output_path gen.proto  --plugin=target/debug/protoc-gen-arkts

Example

syntax = "proto3";
package struct_pkg;

enum Enum {
    ENUM_0 = 0;
    ENUM_1 = 1;
}

message Common {
	string common_id = 1;
	int64 common_type = 2;
}

message Struct {
  string field_string = 1;
  repeated string field_string_list = 2;
  int32 field_i32 = 3;
  repeated int32 field_i32_list = 4;
  int64 field_i64 = 5;
  repeated int64 field_i64_list = 6;
  bool field_boolean = 7;
  repeated bool field_boolean_list = 8;

  bytes field_bytes = 9;
  repeated bytes field_bytes_list = 10;

  Enum field_enum = 11;
  repeated Enum field_enum_list = 12;

  Common field_common_struct = 13;
  repeated Common field_common_struct_list = 14;

  map<string, string> field_map_string_string = 15;
  map<string, int32> field_map_string_i32 = 16;
  map<int64, int64> field_map_i64_i64 = 17;

Development

- cargo install cargo-patch
- cargo-patch
- cargo build

when the compilation is completed, the protoc-gen-arkts will appear in target/debug/

- "google-protobuf": "3.21.2"
- "js-base64": "3.7.7"

add dependencies to the oh-package.json5 file in the project

test

./infra/test.sh
