elm-i18n

I18n helps you generate a lookup function to easily internationalize your applications. It provides a fluent API for building out sets of Strings for different language identifiers and a helper for converting that configuration to a convenient function that allows selection of language and keys as well as interpolation that you can use right in your view functions.

This package is still in early stages and I'm actively seeking feedback and thinking about additional features. Any input and pull requests are very welcome and encouraged. If you'd like to help or have ideas, get in touch with me at @luke_dot_js on Twitter or @luke in the elmlang Slack!

Example

import I18n exposing (withLanguage, createLookup, Language(Language))
-- ...

english : Language
english =
    Language "en-us"

french : Language
french =
    Language "fr-fr"

german : Language
german =
    Language "de-de"

lookup : Language -> String -> List String -> String
lookup =
    createLookup
        [ withLanguage
            french
            [ ( "good day", "bonjour" )
            , ( "I am {0} years old.", "J'ai {0} ans." )
            ]
        , withLanguage
            german
            [ ( "good day", "guten tag" )
            , ( "I am {0} years old.", "Ich bin {0} Jahre alt." )
            ]
        ]

currentLang : Language
currentLang =
  french

i18nText : String -> List String -> String
i18nText =
    lookup currentLang

main =
    show (i18nText "I am {0} years old." ["24"])
