Resdayn

An Elixir application for reading, parsing and formatting data from ESM data files from The Elder Scrolls III: Morrowind. This is everything you can see and edit by loading the ESM file in the Construction Set, but in code format.

This uses the amazing work of Dave Humphrey, who detailed the format of ESM files (and has also been running UESP for many years!): http://www.uesp.net/morrow/tech/mw_esm.txt

Example usage

iex> Resdayn.load("path/to/your/Morrowind.esm")
[
  %{
    company: "Bethesda Softworks",
    dependencies: [],
    description: "The main data file For Morrowind",
    flags: %{blocked: false, persistent: false},
    record_count: 48295,
    type: :master,
    version: 1.2
  },
   %{
    flags: %{blocked: false, persistent: false},
    name: "sMonthMorningstar",
    type: :game_setting,
    value: "Morning Star"
  },
  ...
]
