defmodule Localize.Message.Formatter do

  @moduledoc """

  Dispatch module for rendering MF2 highlight tokens.



  Delegates to one of the format-specific formatter modules based on

  the `:format` option:



  * `:plain` — plain text, discards classes. Used internally to

    produce the canonical MF2 string from a token stream.



  * `:html` — HTML with per-token `<span>` wrappers.

    See `Localize.Message.Formatter.HTML`.



  * `:ansi` — ANSI-coloured terminal output.

    See `Localize.Message.Formatter.ANSI`.



  """



  alias Localize.Message.Highlighter

  alias Localize.Message.Formatter.{ANSI, HTML, Plain}



  @type format :: :plain | :html | :ansi



  @doc """

  Renders a token list in the chosen format.



  ### Arguments



  * `tokens` is a list of `t:Highlighter.token/0` tuples.



  * `format` is one of `:plain`, `:html`, or `:ansi`.



  * `options` is a keyword list of format-specific options.



  ### Returns



  * A rendered string.
