tomgos

tomgos is a simple app to generate Golang struct based on TOML file.

Features

• Detect field type based on value of the TOML
• Detect multiple types of field
  • string
  • int64
  • map[string]interface
  • time
  • slice of type:
    • string
    • int
    • existing/inherited struct
    • map[string]interface
• Detect other struct (inherited struct) as field type

Supported TOML

Just put a TOML file which represent your data. You can make/convert it from JSON from this site: https://toolkit.site/format.html

Example working TOML:

[recipe]
    id = "this-is-id"
    title = "recipe title"
    description = "short description"
    cooking_time = 100
    portion = 1
    create_time = "1987-07-05T05:45:00Z"
    metadata = {}
    chef = ['ridho', 'budi']
    category_ids = [1, 3, 4]
    metas = [{}]

Nested Struct

There are 2 ways for including nested struct as field type

1. Using {video} bracket followed by struct's name inside of it. Example:

   [recipe]
       id = "this-is-id"
       title = "recipe title"
       description = "short description"
       cooking_time = 100
       portion = 1
       create_time = "1987-07-05T05:45:00Z"
       video = "{video}"
   
   [video]
       url = "http://url.com"

   Result:

   package tomgos
   
   import (
   	"time"
   )
   
   type recipe struct {
   	Description string    `json:"description"`
   	CookingTime int64     `json:"cooking_time"`
   	Portion     int64     `json:"portion"`
   	CreateTime  time.Time `json:"create_time"`
   	Video       video     `json:"video"`
   	Id          string    `json:"id"`
   	Title       string    `json:"title"`
   }
   
   type video struct {
   	Url string `json:"url"`
   }

2. Write the children key toml inside the parent key. Example:

   [recipe]
       id = "this-is-id"
       title = "recipe title"
       description = "short description"
       cooking_time = 100
       portion = 1
       create_time = "1987-07-05T05:45:00Z"
   
       [recipe.video]
          url = "http://url.com"
       
       [[recipe.thumbnail]]
          url = "http://image.com" 
   
   [video]
       url = "http://url.com"
   
   [thumbnail]
       url = "http://image.com"

   Result:

   package tomgos
   
   import (
   	"time"
   )
   
   type recipe struct {
   	Thumbnail   []thumbnail `json:"thumbnail"`
   	Id          string      `json:"id"`
   	Title       string      `json:"title"`
   	Description string      `json:"description"`
   	CookingTime int64       `json:"cooking_time"`
   	Portion     int64       `json:"portion"`
   	CreateTime  time.Time   `json:"create_time"`
   	Video       video       `json:"video"`
   }
   
   type video struct {
   	Url string `json:"url"`
   }
   
   type thumbnail struct {
   	Url string `json:"url"`
   }

How to Use

1. Build the binary. Run make
2. Run ./tomgos generate to run the App.
