EAAL (Eve API Access Layer) is a ruby library for accessing data of the API of the game Eve Online

• does not need to change when EVE API gets new pages

• has a build in file cache which respects eve caching times (usage= EAAL.cache = EAAL::Cache::FileCache.new(‘path/to/save/files/in’))

Usage: Initialize the API Object

api = EAAL::API.new("my Userid", "my API key"[, "scope for requests"])

the scope is the one used for the API requests, ex. account/char/corp/eve/map/server see wiki.eve-id.net/APIv2_Page_Index the scope can be changed during runtime and defaults to account

Request Information

result = api.ApiPage

this will return an Object of type ScopeApiPageResult which then can be used to do read the api result

Example 1, getting a list of characters on the account:

api = EAAL::API.new("my userid", "my API key")
result = api.Characters
result.characters.each{|character|
    puts character.name
}

Example 2, getting the id for a given character name

api = EAAL::API.new("my userid", "my API key")
api.scope = "eve"
result = api.CharacterID(:names => "Peter Powers")
puts result.characters.first.characterID

Example 3, Example 2 in short

puts EAAL::Api.new("my userid", "my API key", "eve").CharacterID(:names => "Peter Powers").characters.name

Errors returned by the EVE API are handled a bit unique, since i wanted to have them pretty much dynamic (so i dont need to hack EAAL whenever CCP adds a new Error) you have to use dynamic created classes to catch ‘em (if you dont want to catch EAAL::Exception::EveAPIException in general) so what you do is:

Example 4, catching a specific EVE API Exception

begin
  api.Killlog("characterID" => "12345") #this example offcourse
                                        # assumes your not having the key for character 12345 loaded ;)
rescue EAAL::Exception.EveAPIException(201)
  #dosomething
end

EAAL comes with a simple file cache, which can be used by doing

EAAL.cache = EAAL::Cache::FileCache.new(path)

if you dont give a path it defaults to $HOME/.eaal/cache

Example 5, doing a cached request

require 'eaal'
EAAL.cache = EAAL::Cache::FileCache.new               # set cache
api = EAAL::API.new("my userid", "my API key")        # initialize API object
charid = api.Characters.characters.first.characterID  # get the characterID of the first character on account
api.scope = "char"                                    # set scope to "char"
kills = api.Killlog("characterID" => charid).kills    # request Killlog API Page

both requests in this example will check if the XML is allready available in the cache folder, if it is they will check if cachedUntil expired, if it did requests will be made to the API, if it didnt the XML file will be load.
