Language.Elm.Quasi

This module contains Shakespearean (see Text.Shakespeare) templates for Elm. It introduces type-safe compile-time variable and URL interpolation. A typeclass ToElm is provided for interpolated variables.

Functions

Template-Reading Functions

These QuasiQuoters return functions of the type (t -> Elm) where t is the URL rendering function if type-safe URLs are used.

A usage example for both type-safe (Yesod) and standard path segment (Happstack) URLs is provided in the Examples folder in the Git repository.
