- 2016-01-26 Complete rewrite of parser to support full proto2 and proto3 syntax
- 2014-02-28 Dusted off project and moved to GitHub
- 2012-11-02 blog Parsing a Protocol Buffers .proto File in F#
-
The parser now generates an AST based on Discriminated Unions, rather than objects.
Froto.Parser.Ast(and the underlying parser) now support the full proto2 and proto3 languages. -
The old primary class,
Froto.Parser.ProtoAst.ProtoFilehas been renamed toFroto.Parser.Model.ProtoFileand given static factory methods to simplify access from C#, VB.net, etc.Note that this model curently only supports a subset of the proto2 language. This will be expanded in later releases to fully support proto2 & proto3.

- Load and parse files from import statements. See https://developers.google.com/protocol-buffers/docs/proto3#importing-definitions
- Verify message identifiers used as field types are actually defined and enum values used in option value assignment are actually defined. Note these must handle forward references.
- For option assignment, verify type of literal matches type of option's message field definition.
- Predefine standard options and enums, or load these from an external "descriptor.proto" file. For standard option definitions, see https://github.com/google/protobuf/blob/master/src/google/protobuf/descriptor.proto#L251
- Generate errors with context including file/line/column when any of the above validations fail (note: this might be better than what protoc reports).
- Record enough source information in the AST to generate SourceCodeInfo (see https://github.com/google/protobuf/blob/master/src/google/protobuf/descriptor.proto#L84)
- Record any other information in the AST needed to generate a complete FileDescriptorProto and FileDescriptorSet.
