Class Method Details

.inspect ⇒ String

Description

We’re doing black magic (a.k.a metaprogramming) to set variables directly on this class. When programmers do black magic, they should redefine some basic things that are broken as a side effect. That’s what happens here. To have a proper inspect, we’ve got to re-write it manually. It’s not something I find very clear but anyway, the API is cool so it’s ok for me.

It allows us to see every variable that has been defined on the class by metaprogramming.

Usage

@example:

# Do some magic before
Knowledge.config.environment = :development
learner = Knowledge::Learner.new

learner.use name: :default
learner.variables = { foo: :bar }

learner.gather!

# And then inspect it
puts Knowledge::Configuration.inspect
# => #<Knowledge::Configuration:0x000047116740290980 @foo="bar">

# Wonderful, isn't it?

Parameters

Returns:

  • (String) —

    as expected
