NoTypeAliasConstructorCall

A elm-review rule that forbids using type alias record constructors to create a record.

This rule does not apply to the map functions in Json.Decode.

Examples

For example, in the following code

type alias Foo = 
    { foo : String
    , bar : Bool
    , baz : Float
    }

init : Foo
init = 
    Foo "hello" True 0.2

Foo "hello" True 0.2 will be marked as error.

To be rid of the error, simply do:

type alias Foo = 
    { foo : String
    , bar : Bool
    , baz : Float
    }

init : Foo
init = 
    { foo = "hello"
    , bar = True
    , baz = 0.2    
    }

Usage

After adding elm-review to your project, import this rule from your ReviewConfig.elm file and add it to the config. E.g.:

import NoTypeAliasConstructorCall
import Review.Rule exposing (Rule)

config : List Rule
config =
    [ NoTypeAliasConstructorCall.rule ]

The following code will not report an error

type alias Point =
    { x : Float, y : Float }

point : Decoder Point
point =
    map2 Point
        (field "x" float)
        (field "y" float)
