Formulae         

Nifty precompiled formulae handling

Installation

def deps do
  [{:formulae, "~> 0.11"}]
end

Using

iex|1 ▸ f = Formulae.compile("rem(a, 5) - b == 0")
#ℱ<[
  sigil: "~F[rem(a, 5) - b == 0]",
  eval: &:"Elixir.Formulae.rem(a, 5) - b == 0".eval/1,
  formula: "rem(a, 5) - b == 0",
  guard: nil,
  module: :"Elixir.Formulae.rem(a, 5) - b == 0",
  variables: [:a, :b]
]>
iex|2 ▸ f.eval.(a: 11, b: 1)
true
iex|3 ▸ f.variables
[:a, :b]
iex|4 ▸ f.module
:"Elixir.Formulae.rem(a, 5) - b == 0"
