-- Text interpolation stuff

-- Text interpolation modeled on the @template@ library by Johan Tibell.
-- - This uses Megaparsec instead of an internal State monad parser.
-- - This uses @#@ instead of @$@.
-- - Only the safe parsers are provided.
-- - Only the applicative interface is provided.
-- - We don't support #name, but only #{name}, because # can appear
--   in character entities, URLs, ...
-- TODO Mention the BSD-3 license and Johan.

--------------------------------------------------------------------------------

-- | A mapping from placeholders in the template to values with an applicative
-- lookup function. For instance the lookup function can fail, returning
-- 'Nothing' or 'Left'.
type InterpolationContext f = Text -> f Text

--------------------------------------------------------------------------------
-- Basic interface

-- | Create a template from a template string. A malformed template
-- string will cause 'parse' to return a parse error.
