Warning: This is pre-release software under active development. Not for production use. Breaking changes occur often.

This repo contains several related packages.

DTOMaker.Models

Attributes for defining simple data models as interfaces in C#.

DTOMaker.Core

Core types used by source generators at compile-time, including a common syntax receiver, and a powerful template processor.

Generators

The following source generators depend on this package:

DTOMaker.MessagePack

Generates DTOs decorated with MessagePack attributes (https://github.com/MessagePack-CSharp/MessagePack-CSharp).

DTOMaker.MemBlocks

Generates DTOs whose internal data is a single memory block (Memory<byte>). Property getters and setters decode and encode values directly to the block with explicit byte ordering (little-endian or big-endian).

DTOMaker.CSPoco

Generates basic POCOs (Plain Old C# Objects) that implement the data model interfaces.

Features

Features implemented:

• Data types: Boolean, S/Byte, U/Int16/32/64/128, Double, Single, Half, Char, Guid, Decimal
• IFreezable support
• Templates as code, template processing
• [Obsolete] members
• Fixed length arrays of above types
• DTOMaker.MessagePack source generator
• DTOMaker.MemBlocks source generator
• DTOMaker.CSPoco source generator

Features not implemented:

• Nullable types. T? can be simulated using a pair of fields (Boolean, T).
• Enum data types. An enumeration type can be simulated with a casting property.
• Strings (UTF8). String types can be simulated with a byte array field and a length field.

In progress:

• Json (NewtonSoft) generator

Coming next:

• Json (System.Text) generator
• ProtobufNet 3.0 generator
• other model entities
• member wire names and tags
• reservation (hidden members)
• compact layout method

Coming later:

• C# records generator
• Google Protobuf .proto generation
• polymorphic types
• generic patterns: lists, trees, unions, etc.
• variable length arrays
• logical value equality

These models are consumed by the following source generators to emit DTO classes that implement the model interfaces.
