lint-unused

Provides elm-lint rules to detect unused functions and types in your Elm files.

Provided rules

• NoUnused.Variables - Reports unused top-level variables and types, imports and imported variables and types.
• NoUnused.CustomTypeConstructors - Reports unused constructors for a custom type.

Note

Since elm-lint only works in the scope of a single file, these rules will not report elements that are exposed but not used anywhere in the project. If you wish those to be reported, check out elm-xref.

Example configuration

module LintConfig exposing (config)

import Lint.Rule exposing (Rule)
import NoUnused.Variables
import NoUnused.CustomTypeConstructors

config : List Rule
config =
    [ NoUnused.Variables.rule
    , NoUnused.CustomTypeConstructors.rule
    ]
