# elm-tracery

Interpreter for the Tracery language.

See [Tracery.io](www.tracery.io) for more information.

## Installation

```

elm install Orasund/elm-tracery

```

## How to use

```elm

import Tracery

import Random

import Json.Decode

seed : Random.Seed

seed =

    Random.initialSeed 41

"""

{ "origin":["I have a #favoriteAnimal# named #favoriteAnimalName# and a #animal# named #name#. I love #favoriteAnimalName# the most. It's the best #favoriteAnimal# in the world."]

, "favoriteAnimal" : "#color# #animal#"

, "color": ["white","black","brown"]

, "favoriteAnimalName" : "#name#"

, "animal":["cat","dog","parrot"]

, "name": ["Johnny","Charlie","Twinkle","Charles"]

}

"""

|> Tracery.fromJson

|> (\result ->

    case result of

        Err err -> Json.Decode.errorToString err

        Ok grammar ->

            Random.step (Tracery.run grammar) seed

            |> Tuple.first

    )

--> "I have a black cat named Charles and a parrot named Charlie. I love Charles the most. It's the best black cat in the world."

```

## Differences to the original Tracery

* No support of "saving" values. Instead values can be constant.

* Entry point is always `"origin"`.

* Supporting sub-grammars in favor of the more experimental features of the original.
