module Nanoc::Int
# Provides a context and a binding for use in filters such as the ERB and
# Haml ones.
#
# @api private
class Context
# Creates a new context based off the contents of the hash.
#
# Each pair in the hash will be converted to an instance variable and an
# instance method. For example, passing the hash `{ :foo => 'bar' }` will
# cause `@foo` to have the value `"bar"`, and the instance method `#foo`
# to return the same value `"bar"`.
#
# @param [Hash] hash A list of key-value pairs to make available
#
# @example Defining a context and accessing values
#
# context = Nanoc::Int::Context.new(
# :name => 'Max Payne',
# :location => 'in a cheap motel'
# )
# context.instance_eval do
# "I am #{name} and I am hiding #{@location}."
# end
# # => "I am Max Payne and I am hiding in a cheap motel."
