Using nimler_mix

Github: nimler_mix

Nim and nimler must first be installed. See installation.

  1. Add nimler to mix.exs and run mix deps.get to install nimler from hex.pm
  def deps() do
    [{:nimler, "~> 0.1.1"}]
  end

  1. mix nimler.new to generate scaffold NIF project

  2. mix compile.nimler to compile NIF with nimler

mix nimler.new

Generate basic nimler NIF

Defaults

lib/native is default NIF root

lib/native/nif.nim is default NIF file

lib/native/nim.cfg is default NIF nim configuration. This will be used during compilation. See priv/templates/nim.cfg for current nim.cfg template

mix compile.nimler

Compile NIFs in lib/native

Nimler generates lib/native/nif_wrapper.ex by default

Configuration sample

  def project do
    [
      app: :myproject,
      version: "0.1.0",
      elixir: "~> 1.10",
      start_permanent: Mix.env() == :prod,
      deps: deps(),

      # add the nimler compiler
      compilers: Mix.compilers ++ [:nimler],

      # add optional nimler_config
      nimler_config: nimler_config()
    ]
  end

  def nimler_config() do
    [
      # compile_mode can be one of :debug, :release, :danger
      compile_mode: :debug,

      # compile_flags are passed directly to nim compiler
      # see [priv/templates/nim.cfg](priv/templates/nim.cfg) for default nim cfg
      compile_flags: [
        "--verbosity:2"
      ]
