Public Class Methods

new(target, content=nil) click to toggle source

Constructs a new Instruction @param target can be one of a number of things. If String, then the target of this instruction is set to this. If an Instruction, then the Instruction is shallowly cloned (target and content are copied). If a Source, then the source is scanned and parsed for an Instruction declaration. @param content Must be either a String, or a Parent. Can only be a Parent if the target argument is a Source. Otherwise, this String is set as the content of this instruction.

    @content = target.content
  end
  @content.strip! if @content
