Overview

Package genmain provides a generator for a skeleton goa application. This generator generates the code for a basic “main” package and is mainly intended as a way to bootstrap new applications. The generator creates a main.go file and one file per resource listed in the API metadata. If a file already exists it skips its creation unless the flag –force is provided on the command line in which case it overrides the content of existing files.

type Generator

type Generator struct {
    API       *design.APIDefinition // The API definition
    OutDir    string                // Path to output directory
    DesignPkg string                // Path to design package, only used to mark generated files.
    Target    string                // Name of generated "app" package
    Force     bool                  // Whether to override existing files
    Regen     bool                  // Whether to regenerate scaffolding in place, maintaining controller implementation
    // contains filtered or unexported fields
