Simulates Highline input for use in tests.
Creates a simulator with an array of Strings as a script @param strings [Array<String>] preloaded string to be used
as input buffer when simulating.
# File lib/highline/simulate.rb, line 18 def initialize(strings) @strings = strings end
A wrapper method that temporarily replaces the Highline instance in HighLine.default_instance with an instance of this object for the duration of the block
@param strings [String] preloaded string buffer that
will feed the input operations when simulating.
# File lib/highline/simulate.rb, line 50 def self.with(*strings) @input = HighLine.default_instance.instance_variable_get :@input HighLine.default_instance.instance_variable_set :@input, new(strings) yield ensure HighLine.default_instance.instance_variable_set :@input, @input end
The simulator handles its own EOF
# File lib/highline/simulate.rb, line 39 def eof? false end
Simulate StringIO#getbyte by shifting a single character off of the next line of the script
# File lib/highline/simulate.rb, line 29 def getbyte line = gets return if line.empty? char = line.slice! 0 @strings.unshift line char end
Simulate StringIO#gets by shifting a string off of the script
# File lib/highline/simulate.rb, line 23 def gets @strings.shift end
