LimitRecordSizeConfig gets passed to rule to configure the rule. You can't contruct this type directly, but you can use the maxRecordSize function to create a configuration value:

import LimitAliasedRecordSize
import Review.Rule exposing (Rule)


config : List Rule
config =
    [ LimitAliasedRecordSize.rule
        (20 |> LimitAliasedRecordSize.maxRecordSize)
    ]

Assign the max record size allowed when configuring this rule.

import LimitAliasedRecordSize
import Review.Rule exposing (Rule)


config : List Rule
config =
    [ LimitAliasedRecordSize.rule
        (20 |> LimitAliasedRecordSize.maxRecordSize)
    ]

Configure the rule in your elm-review configuration:

import LimitAliasedRecordSize
import Review.Rule exposing (Rule)


config : List Rule
config =
    [ LimitAliasedRecordSize.rule
        (20 |> LimitAliasedRecordSize.maxRecordSize)
    ]

Examples

✅ Good: not too many fields

type alias MyRecord =
    { oneField : Int
    , anotherField : String
    , yetAnotherField : Bool
    }

❌ Bad: too many fields

type alias MyRecord =
    { oneField : Int
    , anotherField : String
    , yetAnotherField : Bool
    , andAnotherField : Int
    , andAnotherField2 : Int
    , andAnotherField3 : Int
    , andAnotherField4 : Int
    , andAnotherField5 : Int
    , andAnotherField6 : Int
    , andAnotherField7 : Int
    , andAnotherField8 : Int
    , andAnotherField9 : Int
    , andAnotherField10 : Int
    , andAnotherField11 : Int
    , andAnotherField12 : Int
    , andAnotherField13 : Int
    }

How to fix

One simple approach is just to change the record into a custom type. For example, the above bad example can be changed to:

type MyRecord
    = MyRecord
        { oneField : Int
        , anotherField : String
        , yetAnotherField : Bool
        , andAnotherField : Int
        , andAnotherField2 : Int
        , andAnotherField3 : Int
        , andAnotherField4 : Int
        , andAnotherField5 : Int
        , andAnotherField6 : Int
        , andAnotherField7 : Int
        , andAnotherField8 : Int
        , andAnotherField9 : Int
        , andAnotherField10 : Int
        , andAnotherField11 : Int
        , andAnotherField12 : Int
        , andAnotherField13 : Int
        }
