## Description
Generate boilerplates for layered architecture by your templates.
At first, we prepare layered structure and templates.
```bash
$ tree templates
templates
├── repositories
│ └── repository.tmpl
├── controllers
│ └── controller.tmpl
└── usercases
└── usecase.tmpl
```
For instance, the usecase template is below. templates are written with `text/template`.
```go
// templates/usercase/usecase.tmpl
package usecase
type {{ .Action | title}}{{ .Model | title }}Input struct{}
type {{ .Action | title}}{{ .Model | title }}Result struct{}
type {{ .Action | title}}{{ .Model | title }}Usecase interface {
Run({{ .Action | title}}{{ .Model | title }}Input) ({{ .Action | title}}{{ .Model | title }}Result, error)
}
func New{{ .Action | title}}{{ .Model | title }}Usecase() {{ .Action | title}}{{ .Model | title }}Usecase {
return &{{ .Action }}{{ .Model | title }}Usecase{
}
}
type {{ .Action }}{{ .Model | title }}Usecase struct {}
func (u *{{ .Action }}{{ .Model | title }}Usecase) Run(
in {{ .Action | title}}{{ .Model | title }}Input,
) ({{ .Action | title}}{{ .Model | title }}Result, error){
// Need to implement usercase logic
return {{ .Action | title}}{{ .Model | title }}Result{
// Need to build result
}
}
```
Execute `lgen` with `Action` and `Model` strings.
```bash
$ lgen -action Get -model User -template ./testdata -dist myproduct
```
The generated directories and files are below.
```bash
$ tree myproduct
myproduct
├── repositories
│ └── get_user_repository.go
├── controllers
│ └── get_user_controller.go
└── usercases
└── get_user_usecase.go
2 directories, 2 files
```
The get_user_usercase.go is below. We are enabled to write miltiple files by a command.
```go
package usecase
type GetUserInput struct{}
type GetUserResult struct{}
type GetUserUsecase interface {
Run(GetUserInput) (GetUserResult, error)
}
func NewGetUserUsecase() GetUserUsecase {
return &getUserUsecase{}
}
type getUserUsecase struct{}
func (u *getUserUsecase) Run(
in GetUserInput,
) (GetUserResult, error) {
// Need to implement usercase logic
return GetUserResult{
// Need to build result
}
}
```
## Synopsis
```
$ lgen -a get -m user -template /your/templates/directory -dist /your/project/root/directory
```
## Options
```
$ lgen -h

```
## Installation
```
$ go get github.com/budougumi0617/lgen
```
Built binaries are available on gihub releases. https://github.com/budougumi0617/lgen/releases
### MacOS
If you want to install on MacOS, you can use Homebrew.
```
brew install budougumi0617/tap/lgen
```
## Template rules
The template must be created according to the following rules.
1. Base on `text/template` package.
1. template file extension is only `.tmpl`.
1. Varialbes are `Action`, and `Model` only.

1. `title` - [`strings.ToTitle`](https://golang.org/pkg/strings/#ToTitle)
## Contribution
1. Fork ([https://github.com/budougumi0617/lgen/fork](https://github.com/budougumi0617/lgen/fork))
2. Create a feature branch
3. Commit your changes
4. Rebase your local changes against the master branch
5. Run test suite with the `go test ./...` command and confirm that it passes
6. Run `gofmt -s`
7. Create new Pull Request
