#force_add(i) ⇒ Object

#

force_add

This method will force-add a specific configure option.

Additionally, it will replace any contradictory configuration options, and thus guarantees that our resulting string will be sane.

#return_duplicates(i) ⇒ Object

#

return_duplicates

This method will return keys which are duplicates (or in other words, all entries which occur more than once). ” is ignored though as I can’t see it being useful for anything much really.

The file “rbt/lib/rbt/exclusive_logic.rb” needs this method.

Example:

['foo', 'bar', 'ble', 'foo', 'ble', 'go','yo','',''].return_duplicates # => ["ble", "foo"]

  hash = Hash.new(0)
  i.each { |word| hash[word] += 1 }
  hash.select {|key, value|
    return_value << key if value > 1 and ! key.empty?
  }
  return_value = [] if return_value.empty?
  return return_value

def run
  scan_string

#sanitize_string(i) ⇒ Object

#

sanitize_string

This method replaces ‘ ’ with ‘ ’ and then goes to split at ‘ ’ before it returns an array.

def sanitize_string(i)
  i.squeeze(' ').split(' ') if i
end

#scan_string ⇒ Object

#

scan_string

This is the actual powerhorse. It also sets the @problems variable in case it encountered a problem.

#split_up_string_properly ⇒ Object

#

split_up_string_properly

The .map is used to omit the leading ./configure word. We use .squeeze to get rid of multiple ‘ ’
