Simple type generator

Uses handlebars to generate types for multiple languages from a common definition.

Currently two pre-written templates for types with serialization in TypeScript and C++ exists.

Handles basic types like

• uint8
• uint16
• uint32
• float
• string
• arrays (std::vector in c++)
• variants (std::variant in c++, in TS represented as { type: number, value: string | number })

Your custom types can reference each other.

Short example:

const BarDefinition: TypeDefinition = {
  name: "Bar",
  members: [
    { name: "name", type: "string" },
    { name: "id", type: "uint8|string" }, // variant<uint8 | string>
    { name: "foo", type: "Foo" }, // custom type
    { name: "values", type: ["Foo|uint8|uint16"] }, // array<variant<Foo|uint8|uint16>>
  ],
};

const FooDefinition: TypeDefinition = {
  name: "Foo",
  members: [
    { name: "name", type: "string" },
    { name: "id", type: "uint16" },
    { name: "values", type: ["uint8"] }, // array<uint8>
  ],
};

Known limitations:

No nested arrays or variant

This means no array<array<uint8>> or variant<uint8|variant<string|float>>

Keep it simple.

How to run

Requires deno.

Update the type definitions in main.ts and run deno task generate

You can run this with node/npm if you want, requires transpiling.
