Changelog

v0.11.0

Enhancements

  • Improve formatting in generated code.
  • Fix JSON encoding of field masks.
  • Fix return value of Protobuf.JSON.RFC3339.encode/2.
  • Improve error message when encoding oneoff.
  • Add support for proto3 optional field.

Bug fixes

  • Fix encoding root structs with transform module.
  • Fix a bug with negative durations in JSON.
  • Fix enum default value for structs where module is not available.
  • Support transform module in JSON encoder.

v0.10.0

Enhancements

  • Add Protobuf.get_unknown_varints/1, returns fields that could not be decoded.
  • Support JSON mapping for proto2 schemas.
  • No longer warn when decoding unknown enum values.
  • Validate options in Protobuf.JSON.encode/2.
  • Raise Protobuf.DecodeError instead of CaseClauseError when trying to decode an unknown wire type.
  • Raise Protobuf.DecodeError instead of MatchError when trying to decode invalid delimeted types.
  • Include protoc-gen-elixir plugin version in generated files.

Bug fixes

  • Encode fields in the order they are defined in the schema.
  • Encode the value of oneof fields even when it's the default value.
  • Camelization fixes in generated code using the module_prefix and package_prefix options.
  • Add nil to oneof typespec union.
  • Skip calling Type.new/1 for structs with transform modules.

Deprecations

  • Warn if @type t is defined inside a module that calls use Protobuf. To fix this warning the files can be regenerated with the latest version of protobuf.

Breaking changes

  • Raise an error if only @type t or defstruct is defined inside a module that calls use Protobuf.

v0.9.0

Enhancements

Most of the enhancements in this release concern JSON support.

  • JSON support for Google types. The library now supports JSON mapping of Google.Protobuf.* types such as timestamps, durations, type wrappers, and so on. In order to use this correctly, you need to manually generate the Protobuf Elixir files from the .proto files provided by Google since they are not shipped with this library.
  • Accept integer numbers for float fields when decoding JSON.
  • Add Protobuf.encode_to_iodata/1.
  • Add the one_file_per_module CLI option when using the protoc-gen-elixir plugin.
  • Use type-aware defaults in struct definitions for Protobuf messages. This means that now doing %MyMessage{} should be equivalent to MyMessage.new().
  • Don't generate the transformer_module/0 callback in generated Protobuf modules if the transformer_module CLI option is not used.

Bug fixes

  • Fix enum aliasing in JSON mapping.
  • Fix encoding of default values when using transformer modules.
  • Raise a Protobuf.DecodeError when decoding if fields with number 0 are encountered.
  • Fix bugs when decoding big varints, integers, and so on (by casting).
  • Cast enum integers to int32 when they overflow when decoding.
  • Skip encoding for fields if they match their user-defined default in proto2.
  • Fix decoding and encoding of packed repeated fields.
  • Don't pack fields that use the [packed = false] option explicitly in proto3.

v0.8.0

Enhancements

  • JSON encoding and decoding support.
  • Extensions support.
  • Enum alias (allow_alias) support.
  • Faster and more memory-efficient encoding and decoding algorithms.
  • More accurate typespecs for repeated fields and enums.
  • Add package_prefix command-line option to control namespacing on generated code.
  • Add transform_module command-line option with hooks for custom pre-encode and post-decode logic.

Bug fixes

  • Fix decoding of proto2 payloads containing legacy group fields. Instead of crashing the decoder, those fields are now skipped.
  • Fix compilation warnings on recent versions of Elixir.
  • Fix new! to raise ArgumentError when given struct and module don't match.

Breaking changes

  • Dropped support to OTP 21.1 and lower.

v0.7.1 (2020-01-07)

Enhancements

  • Add typespec generation for enum fields.
  • Add new!/1 function to generated modules with strict field validation.
  • Raise Protobuf.DecodeError when unable to decode binary input.
  • Add --version command-line flag.

v0.7.0 (2019-12-19)

v0.6.3 (2019-08-19)
