Tutor



[![Build Status](https://travis-ci.org/davidchambers/tutor.svg?branch=master)](https://travis-ci.org/davidchambers/tutor)



[Gatherer][1] is the canonical source for _Magic: The Gathering_ card details.

While useful, it lacks an interface for retrieving this data programmatically.

The lack of an API makes creating _Magic_-related applications unnecessarily

difficult.



Tutor is a simple JavaScript interface for Gatherer.



### API



  - [tutor.card](#tutorcard)

  - [tutor.set](#tutorset)

  - [tutor.formats](#tutorformats)

  - [tutor.sets](#tutorsets)

  - [tutor.types](#tutortypes)



### tutor.card



    tutor.card(id, callback(err, card))

    tutor.card(name, callback(err, card))

    tutor.card(details, callback(err, card))



The first and second forms are shorthand for `tutor.card({id: id}, ...)` and

`tutor.card({name: name}, ...)` respectively. The callback is passed an object

representing the specified card. Version-specific metadata such as flavor text

and rarity are included for cards specified by id. Attributes not applicable

to the card type (e.g. lands have no mana cost) or not present (e.g. certain

creatures have no rules text) are omitted.



```coffeescript

tutor.card 'Demonic Tutor', (err, card) ->

  console.log card.name

  # => "Demonic Tutor"

  console.log card.mana_cost

  # => "{1}{B}"

  console.log card.text

  # => "Search your library for a card, put that card into your hand, then shuffle your library."

```



#### Split cards



Because the two sides of a split card share a Gatherer id, it's necessary to

provide the name of the desired side:



```coffeescript

tutor.card id: 27165, name: 'Fire', (err, card) ->

  console.log card.name

  # => "Fire"



tutor.card id: 27165, name: 'Ice', (err, card) ->

  console.log card.name

  # => "Ice"

```



Retrieving either side of a split card by name is straightforward:



```coffeescript

tutor.card 'Fire', (err, card) ->

  console.log card.name

  # => "Fire"



tutor.card 'Ice', (err, card) ->

  console.log card.name

  # => "Ice"

```



#### Flip cards



Retrieving the top half of a flip card by id is straightforward:



```coffeescript

tutor.card 247175, (err, card) ->

  console.log card.name

  # => "Nezumi Graverobber"

```



Either half of a flip card can be retrieved explicitly by setting `which` to

`"a"` (for the upper half) or `"b"` (for the lower half):



```coffeescript

tutor.card id: 247175, which: 'b', (err, card) ->

  console.log card.name

  # => "Nighteyes the Desecrator"

```



When retrieving a flip card by name rather than id, one may simply provide the

name of the desired half:



```coffeescript

tutor.card 'Nighteyes the Desecrator', (err, card) ->

  console.log card.name

  # => "Nighteyes the Desecrator"

```



#### Double-faced cards



Either face of a double-faced card can be retrieved by id:



```coffeescript

tutor.card 262675, (err, card) ->

  console.log card.name

  # => "Afflicted Deserter"



tutor.card 262698, (err, card) ->

  console.log card.name

  # => "Werewolf Ransacker"

```



Or by name:



```coffeescript

tutor.card 'Afflicted Deserter', (err, card) ->

  console.log card.name

  # => "Afflicted Deserter"



tutor.card 'Werewolf Ransacker', (err, card) ->

  console.log card.name

  # => "Werewolf Ransacker"

```



### tutor.set



    tutor.set(name, callback(err, set))



Scrape cards from the set specified by `name`. For example:



```coffeescript

tutor.set 'Homelands', (err, cards) ->

  console.log cards.length

  # => 115

  console.log Object.keys(cards[0]).sort()

  # => [

  #   "converted_mana_cost",

  #   "expansion",

  #   "gatherer_url",

  #   "image_url",

  #   "mana_cost",

  #   "name",

  #   "power",

  #   "rarity",

  #   "subtypes",

  #   "supertypes",

  #   "text",

  #   "toughness",

  #   "types",

  #   "versions"

  # ]

```



### tutor.formats



    tutor.formats(callback(err, formatNames))



Provides the names of all the game's formats:



```coffeescript

tutor.formats (err, formatNames) ->

  console.log formatNames

  # => [

  #   "Brawl",

  #   "Commander",

  #   "Legacy",

  #   "Modern",

  #   "Pauper",

  #   "Standard",

  #   "Vintage"

  # ]

```



### tutor.sets



    tutor.sets(callback(err, setNames))



Provides the names of all the game's sets:



```coffeescript

tutor.sets (err, setNames) ->

  console.log setNames

  # => [

  #   "Aether Revolt"

  #   "Alara Reborn",

  #   ...

  #   "Zendikar",

  #   "Zendikar Expeditions"

  # ]

```



### tutor.types



    tutor.types(callback(err, types))



Provides the names of all the game's types:



```coffeescript

tutor.types (err, types) ->

  console.log types

  # => [

  #   "Artifact",

  #   "Basic",

  #   ...

  #   "World",

  #   "You'll"

  # ]

```



### CLI



`npm install tutor --global` will make the `tutor` command available globally.



    $ tutor card 'Demonic Tutor'

    Demonic Tutor {1}{B} Search your library for a card, put that card into your hand, then shuffle your library.



    $ tutor card 'Demonic Tutor' --format json | jq '{name,mana_cost,types,text}'

    {

      "name": "Demonic Tutor",

      "mana_cost": "{1}{B}",

      "types": [

        "Sorcery"

      ],

      "text": "Search your library for a card, put that card into your hand, then shuffle your library."

    }



    $ tutor card 666 --format json | jq '{name,mana_cost,types,text}'

    {

      "name": "Lich",

      "mana_cost": "{B}{B}{B}{B}",

      "types": [

        "Enchantment"

      ],

      "text": "As Lich enters the battlefield, you lose life equal to your life total.\n\nYou don't lose the game for having 0 or less life.\n\nIf you would gain life, draw that many cards instead.\n\nWhenever you're dealt damage, sacrifice that many nontoken permanents. If you can't, you lose the game.\n\nWhen Lich is put into a graveyard from the battlefield, you lose the game."

    }



    $ tutor set Alliances | head -n 2

    Aesthir Glider {3} 2/1 Flying Aesthir Glider can't block.

    Agent of Stromgald {R} 1/1 {R}: Add {B}.
