SelfFunctions

Installation

  Pkg.clone("https://github.com/fcard/SelfFunctions.jl")

Introduction

This package allows the creation of functions that have easier interaction with a given type, by having an instance of it as an implicit argument and having access to its fields directly.

Usage

Use preexisting type

  using SelfFunctions

  type MyType
    x::Int
  end
  @selftype self MyType

Define and then use type

  using SelfFunctions

  @selftype self type MyType
    x::Int
  end

Usage of the generated macro

  @self function inc()
    x += 1
  end

  @self function inc2()
    inc()
    inc()
  end

  const mt = MyType(0)

  inc(mt)  # mt.x: 0 -> 1
  inc2(mt) # mt.x: 1 -> 3
