This library enables Elixir applications to log to the Windows Event Log, using the Logger interface. It makes use of Rust's winlog crate. Docs can be found at https://hexdocs.pm/ex_winlog.

Since this library uses Rustler, you must have Rust installed on the machine when compiling.

def deps do
  [
    {:ex_winlog, "~> 0.2"}
  ]
end

Since ExWinlog is a Logger backend, you can add it to your list of backends in your config.exs file like this:

config :logger,
  backends: [:console, {ExWinlog, "My Event Source Name"}]

The ExWinlog backend requires that the event source, "My Event Source Name" in the example, is registered with Windows Event Viewer. Use ExWinlog.register/1 and ExWinlog.deregister/1, while running the application as an administrator, to manage the sources. This should typically be done once when installing or uninstalling the application.
