@basketry/sorbet

Sorbet

Basketry generator for generating Sorbet types and interfaces. This parser can be coupled with any Basketry parser.

Quick Start

The following example converts a "Swagger" doc into Sorbet types:

1. Save https://petstore.swagger.io/v2/swagger.json as petstore.json in the root of your project.
2. Install packages: npm install -g basketry @basketry/swagger-2 @basketry/sorbet
3. Generate code: basketry --source petstore.json --parser @basketry/swagger-2 --generators @basketry/sorbet --output src

When the last step is run, basketry will parse the source file (petstore.json) using the specified parser (@basketry/swagger-2) and then run each specified generator (in this case only @basketry/sorbet) writing the output folder (src).

Folder Structure

This generator emits a folder structure suitable for loading classes with Zeitwerk. All files are written to the /{title}/v{majorVersion} subfolder within the output directory. The default structure can be customized using various options.

Example config without options:

{
  "source": "petstore.json",
  "parser": "@basketry/swagger-2",
  "generators": ["@basketry/sorbet"],
  "output": "app/lib"
}

Resulting output:

my_project/
├─ app/
│  ├─ lib/
│  │  ├─ petstore/
│  │  │  ├─ v1/
│  │  │  │  ├─ some_enum_a.rb
│  │  │  │  ├─ some_enum_b.rb
│  │  │  │  ├─ some_interface_a.rb
│  │  │  │  ├─ some_interface_b.rb
│  │  │  │  ├─ some_type_a.rb
│  │  │  │  ├─ some_type_b.rb
│  │  ├─ .gitattributes
├─ basketry.config.json
├─ petstore.json

Options

All sorbet generator options are namespaced within a sorbet property as shown in the following example config:

{
  "source": "petstore.json",
  "parser": "@basketry/swagger-2",
  "generators": [
    {
      "rule": "@basketry/sorbet",
      "options": {
        "sorbet": {
          "includeVersion": false,
          "typesModule": "types",
          "enumsModule": "enums",
          "interfacesModule": "services",
          "types": {
            "number": "BigDecimal"
          }
        }
      }
    }
  ],
  "output": "app/lib"
}

includeVersion

This option controls whether or not the files will be written into a /v{majorVersion} subfolder. The default is true.

Example usage:

{
  "rule": "@basketry/sorbet",
  "options": {
    "sorbet": {
      "includeVersion": false
    }
  }
}

Resulting output:

my_project/
├─ app/
│  ├─ lib/
│  │  ├─ petstore/
│  │  │  ├─ some_enum_a.rb
│  │  │  ├─ some_enum_b.rb
│  │  │  ├─ some_interface_a.rb
│  │  │  ├─ some_interface_b.rb
│  │  │  ├─ some_type_a.rb
│  │  │  ├─ some_type_b.rb
│  │  ├─ .gitattributes
├─ basketry.config.json
├─ petstore.json

typesModule

This option allows you to specify the sub-folder (and sub-module) for the emitted types. If this option is not supplied, types are written into the main project output folder.

{
  "rule": "@basketry/sorbet",
  "options": {
    "sorbet": {
      "typesModule": "types"
    }
  }
}

Resulting output:

my_project/
├─ app/
│  ├─ lib/
│  │  ├─ petstore/
│  │  │  ├─ v1/
│  │  │  │  ├─ types/
│  │  │  │  │  ├─ some_type_a.rb
│  │  │  │  │  ├─ some_type_b.rb
│  │  │  │  ├─ some_enum_a.rb
│  │  │  │  ├─ some_enum_b.rb
│  │  │  │  ├─ some_interface_a.rb
│  │  │  │  ├─ some_interface_b.rb
│  │  ├─ .gitattributes
├─ basketry.config.json
├─ petstore.json

enumsModule

This option allows you to specify the sub-folder (and sub-module) for the emitted types. If this option is not supplied, enums are written into the main project output folder.

{
  "rule": "@basketry/sorbet",
  "options": {
    "sorbet": {
      "enumsModule": "enums"
    }
  }
}

Resulting output:

my_project/
├─ app/
│  ├─ lib/
│  │  ├─ petstore/
│  │  │  ├─ v1/
│  │  │  │  ├─ enums/
│  │  │  │  │  ├─ some_enum_a.rb
│  │  │  │  │  ├─ some_enum_b.rb
│  │  │  │  ├─ some_interface_a.rb
│  │  │  │  ├─ some_interface_b.rb
│  │  │  │  ├─ some_type_a.rb
│  │  │  │  ├─ some_type_b.rb
│  │  ├─ .gitattributes
├─ basketry.config.json
├─ petstore.json

interfacesModule

This option allows you to specify the sub-folder (and sub-module) for the emitted types. If this option is not supplied, interfaces are written into the main project output folder.

{
  "rule": "@basketry/sorbet",
  "options": {
    "sorbet": {
      "interfacesModule": "services"
    }
  }
}

Resulting output:

my_project/
├─ app/
│  ├─ lib/
│  │  ├─ petstore/
│  │  │  ├─ v1/
│  │  │  │  ├─ services/
│  │  │  │  │  ├─ some_interface_a.rb
│  │  │  │  │  ├─ some_interface_b.rb
│  │  │  │  ├─ some_enum_a.rb
│  │  │  │  ├─ some_enum_b.rb
│  │  │  │  ├─ some_type_a.rb
│  │  │  │  ├─ some_type_b.rb
│  │  ├─ .gitattributes
├─ basketry.config.json
├─ petstore.json

magicComments

This option allows you to add magic comments to the files emitted by this generator.

{
  "rule": "@basketry/sorbet",
  "options": {
    "sorbet": {
      "magicComments": ["frozen_string_literal: true"]
    }
  }
}

types

This option allows you to specify overrides for various types.

The following example will cause the generator to emit BigDecimal (instead of the default Numeric) for the type number. Multiple type overrides may be specified.

{
  "rule": "@basketry/sorbet",
  "options": {
    "sorbet": {
      "types": {
        "number": "BigDecimal"
      }
    }
  }
}
