Repository Maker

Helping you to generate the implements for the repository interfaces you defined

Installation

$ go install github.com/yukiouma/repo-maker/cmd/repomaker@latest

Usage

For example, we start with the project structure as follow:

./example/
├── adapter
│   └── datasource
└── domain
    └── repo.go

We define the repository interface in example/domain/repo.go

package domain

import (
	"context"
)

// +repo.impl
type Repo interface {
	CreateUser(ctx context.Context, req *CreateUserRequest) (*CreaetUserReply, error)
	RemoveUser(context.Context, *RemoveUserRequest) (*RemoveUserReply, error)
}

type CreateUserRequest struct{}

type CreaetUserReply struct{}

type RemoveUserRequest struct{}

type RemoveUserReply struct{}

Please make sure write comment // +repo.impl for Repository interface definition

Then generate implements with repomaker

$ repomaker --in ./example/domain --out ./example/adapter/datasource

Implement file repo.impl.go will be generated in ./example/adapter/datasource

./example/
├── adapter
│   └── datasource
│       └── repo.impl.go
└── domain
    └── repo.go

Content of repo.impl.go

package datasource

import (
	"context"

	domain "github.com/yukiouma/repo-maker/example/domain"
)

type Repo struct {
}

func NewRepo() domain.Repo {
	return &Repo{}
}

func (r *Repo) CreateUser(ctx context.Context, req *domain.CreateUserRequest) (*domain.CreaetUserReply, error) {
	panic("Unimplemenet")
}

func (r *Repo) RemoveUser(context.Context, *domain.RemoveUserRequest) (*domain.RemoveUserReply, error) {
	panic("Unimplemenet")
}

After that, you need to complete the logic for the implement

TODO

1. Handle function type parameters
2. Handle interfac{} type parameters
