scaffolding via go templates

Installation

go install gitlab.com/metakeule/scaffold@latest

Usage

given the following template (file models.templ)

{
    "Models": [
        {   "Name": "",
            "Fields": [ {"Name": "", "Type": ""} ] }
    ]
}

>>>models/
{{range .Models}}
>>>{{toLower .Name}}/
>>>model.go
package {{replace .Name "_" "."}}

type {{camelCase1 .Name}} struct {
{{range .Fields}}
    {{camelCase1 .Name}} {{.Type}}
{{end}}
}
<<<model.go
<<<{{toLower .Name}}/
{{end}}
<<<models/

and the following json (file models.json)

{
    "Models": [
        {
            "Name": "person",
            "Fields": [
                {"Name": "first_name","Type": "string"},
                {"Name": "last_name" ,"Type": "string"}
            ]
        },
        {
            "Name": "address",
            "Fields": [
                {"Name": "street_no","Type": "string"},
                {"Name": "city","Type": "string"}
            ]
        }
    ]
}

when running the command

scaffold -t=models.templ < models.json

the following directory structure would be build:

models
├── address
│   └── model.go
└── person
    └── model.go

where models/address/model.go contains

package address

type Address struct {
    StreetNo string
    City string
}

and models/person/model.go contains

package person

type Person struct {
    FirstName string
    LastName string
}

To help generating a template from an existing file structure, make sure, you just have one item per collection and then run

scaffold scan --scandir=your/dir

and edit your template as you need.
