Package generator contains the code generation algorithms for a service server, client, and OpenAPI specification.
The code generated for the service server and client includes:
- A `service` package that contains the declarations for the service interfaces and endpoints which wrap the service methods. - A `views` package that contains code to render a result type using a view. - transport specific packages for each of the transports defined in the design. - An example implementation of the client, server, and the service.
The OpenAPI generator generates a OpenAPI v2 specification for the service REST endpoints. This generator requires the design to define the HTTP transport.
var Generators = generators
Generators returns the qualified paths (including the package name) to the code generator functions for the given command, an error if the command is not supported. Generators is a public variable so that external code (e.g. plugins) may override the default generators.
Example iterates through the roots and returns files that implement an example service, server, and client.
Generate runs the code generation algorithms.
OpenAPI iterates through the roots and returns the files needed to render the service OpenAPI spec. It produces OpenAPI specifications only if the roots define a HTTP service.
Service iterates through the roots and returns the files needed to render the service code. It returns an error if the roots slice does not include a goa design.
Transport iterates through the roots and returns the files needed to render the transport code. It returns an error if the roots slice does not include at least one transport design.
Genfunc is the type of the functions invoked to generate code.
