Editor's Notes
Shared dynamic subsystemStandard hosting environmentFull access to the CLREnable fast generation of dynamic codeProductivity gainsDSL’s rule the world, unfortunately most of those DSL’s are in XML * config files * manifests * build scripts=> Why use xml?To quote Phil Haack: Friends don’t let friends do XML. This pretty much sums up how I feel about xml as well.**** Demo Ninject configuration ****
Many people that come to Ruby do so through the Rails framework.And then often you can hear these people say:I came for Rails but I stayed for RubyRuby is a pleasant language to work with, partly because its well-chosen keywords, but mostly because it represents a kind of best breed implementation of a programming language. One of the goals ruby tries to achieve is to make the language you use ,when you’re writing your algorithms, a lot like a natural language. For example ruby has both the keywords if and unless, and you can apply those in 2 different ways. Best of breed Duck typing Everything is an object Classes are open / monkey patching Flexible Functional Procedural meta programming
Get into dynamic typing before duck typingRuby cares about typesIt cares about hierarchy + mixins when doing method lookupOnly safe operations against an object (no magic)Conversions explicit stepYou can override operators to allow for implicit conversion => explicit step + you’re in controlExplain how static typing resembles aristocracy with their bloodlines and how heritage is more important than capabilitiesExplain how duck typing focusses on the abilities of objects instead of their type. If the method is there it’s all good
