Marat's Notes

Just released small hex package for Elixir (GitHub link), for fetching exchange rates from (Central Bank of the Russian Federation).

Get daily data (for today’s date):

iex(1)> CbrElixir.daily
  %CbrElixir.Models.ValuteCurses{valcurs: [%CbrElixir.Models.Valute{charcode: "AUD",
     id: "R01010", name: "Австралийский доллар", nominal: 1,
     numcode: "036", value: "45,8701"},
    %CbrElixir.Models.Valute{charcode: "AZN", id: "R01020A",
     name: "Азербайджанский манат", nominal: 1,
     numcode: "944", value: "35,4713"},
    %CbrElixir.Models.Valute{charcode: "GBP", id: "R01035",
     name: "Фунт стерлингов Соединенного королевства",
     nominal: 1, numcode: "826", value: "78,2273"}

Get data for specific date:

iex(1)> CbrElixir.daily("03.08.2014")
  %CbrElixir.Models.ValuteCurses{valcurs: [%CbrElixir.Models.Valute{charcode: "AUD",
     id: "R01010", name: "Австралийский доллар", nominal: 1,
     numcode: "036", value: "43,9016"},
    %CbrElixir.Models.Valute{charcode: "AZN", id: "R01020A",
     name: "Азербайджанский манат", nominal: 1,
     numcode: "944", value: "57,4120"},
    %CbrElixir.Models.Valute{charcode: "GBP", id: "R01035",
     name: "Фунт стерлингов Соединенного королевства",
     nominal: 1, numcode: "826", value: "93,9403"}

Get currencies catalog:

iex(1)> CbrElixir.valute_catalog
  %CbrElixir.Models.Valutes{items: [%CbrElixir.Models.Item{engname: "Moldova Lei",
     id: "R01500", name: "Молдавский лей", nominal: 10,
     parentcode: "R01500"},
    %CbrElixir.Models.Item{engname: "US Dollar", id: "R01235",

    %CbrElixir.Models.Item{engname: "S.African Rand", id: "R01810",
     name: "Южноафриканский рэнд", nominal: 10,
     parentcode: "R01810"}

Get specific currency rate by charcode:

iex(4)> CbrElixir.daily_by_code(:EUR, '31-12-2001')
  %CbrElixir.Models.Valute{charcode: "EUR", id: "R01239", name: "Евро",
     nominal: 1, numcode: "978", value: "26,4900"}
