Help me with this Numerology code please...

Hi,

I am planning to implement a Numerology code like this.

Every alphabet in Numerology is given a number like this...

--------------------------------------------------------------
1 2 3 4 5 6 7 8 9

A B C D E F G H I

J K L M N O P Q R

S T U V W X Y Z
----------------------------------------------------------

Or you can even say that

1 = A, J, S
2 = B, K, T
3 = C, L, U
4 = D, M, V
5 = E, N, W
6 = F, O, X
7 = G, P, Y
8 = H, Q, Z
9 = I, R

Now when you type RUBY you should get the total as 9+3+2+7 = (21) 2+1 =
3
where R = 9, U = 3, B = 2 and y = 7 ( as shown above )

Have a look at the working example here...

http://www.numerology.googlepages.com/Numerology_nameNumberdetails.htm

and

http://www.numerology.googlepages.com/Numerology_nameNumber.htm

I would like to code this in Ruby. Pl. help me with this code.

Thanks

( unpack("C*") gives you the ASCII value of each character in the string)

(The ASCII value of A is 65)

Hi Reservoir,

i think this code satisfy your need...

"i"=>9,"r"=>9}


num=[]
i=0
while i < a.length do
num << val[a[i,1]]
i+=1
end
mind(num)
end


def mind(num)
no=[]
no=num
j=0

final=0
while j < no.length
final +=num[j].to_i
j+=1
end
output= final.to_s
if output.length !=1
output2=output.split(//)

Hi Sebastian,

Thanks a lot for your helping attitude. Unfortunately its too tough for
me to understand yiour code at this stage. May be after more homework,
perhaps i will be able to do it.

Meantime, i am looking at the other code given below.

Thanks

Hi Raveendran,

I will be getting most of the details from the web only.
i will be using like this..

myvariable = gets() # can be any name

I cannot depend on any particular name. The name RUBY was just an
example as a work around.

Pl. try the link, which i have given in my first thread. I would like to
work that way.

I am thankful to You and Sebastian for your help. Can you be more
specific, on how to run this code with the gets() solution.

I am trying to understand your code, but i have not understood it
completely. may be due to my less knowledge.

I hope i have made my point clear.

Thanks

Hi Reservior,

trail.rb

Replace the line

a="mahalingam" # your name

Add
puts "Please Enter the name"
b=gets()
a=b.downcase!

Now run the program via command prompt:

EXACT_PATH> ruby trail.rb

1}.to_s.split(//).inject(0) {|s,x| s + x.to_i}
=> 3

Nice code!

"RUBY".unpack("C*").inject(0) { |s,x| s + (x-64)%9 }%9
=> 3

whouldn't that be better?

You're working waaaaay too hard :) Let Ruby do the heavy lifting.

class Reservoir

# This technique is a little odd at first, but it's actually a
# pretty common idiom.
MAP = Hash[*('a'..'z').zip(1..26).flatten]

# Convert "abc" or 123 to [1,2,3]
# This is fairly terse code, but it's just a utility method that
# will be called from higher-level logic.
def numbers_from(obj)
obj.to_s.split(//).map {|letter| MAP[letter] || letter.to_i }
end

# The classic Ruby way to add up an array. See Array#sum in
# ActiveSupport too.
def add_up(numbers)
numbers.inject(0) {|acc,n| acc + n }
end

def numberize(object)
final = add_up(numbers_from(object))
if final > 9
numberize(final)
else
final
end
end
end

r = Reservoir.new
p r.numberize("david")
p r.numberize(1234) # extra functionality :)

The inclusion of numberizing numbers may or may not be desired, but if
not, it should be pretty easy to get rid of.

I think the original poster may be new to coding, in which case, can I
recommend the first couple of chapters of "_Why's Poignant Guide to
Ruby"? People tend to either find it really useful, or hate it, I
think. http://poignantguide.net/ruby/

At the risk of adding even more meat to the pot:

def numerologise(name)
# turn name into an array of integers
arr = name.upcase.unpack("C*").map{|x| (x - ?A) % 9 + 1}

# keep going until there's only one integer in the array
until (arr.size == 1)
# add up all the integers
tot = arr.inject{|c,x| c + x}

# split the digits to make a new array
arr = tot.to_s.split(//).map{|y| y.to_i}
end

return arr
end

puts numerologise("ruby")

(This is basically Sebastian's original answer, although perhaps it's
easier to understand like this.)

Obviously the harder to understand, the better.

There's also the small issue it gives inconsistent results.

irb(main):022:0> Name='I'
=> "I"
irb(main):023:0> Name.unpack("C*").inject(0) {|s,x| s + (x-65)%9 +
irb(main):024:1* 1}.to_s.split(//).inject(0) {|s,x| s + x.to_i}
=> 9
irb(main):025:0> Name.unpack("C*").inject(0) { |s,x| s + (x-64)%9 }%9
=> 0

And neither of these handle the case where you have to go through more
than two reductions.

The OP seems to be just learning ruby, so let's make this a learning exercise by
turning the manual process directly into code.
-Adam
---------------Numberology.rb------------------------------------
# first make a table to hold the number for every letter
number_of = {}
i = 1 #starting with 1...
('A'..'Z').each {|letter| #go through all the letters...
number_of[letter] = i #and assign a number
i+=1 #increase the number for the next letter
i=1 if i>9 #go back to 1 after 9
}
i=0 #do the same thing for ....
('0'..'9').each{|digit| #the text representation of each number
number_of[digit] = i
i+=1
}

namenumber=0 #make a variable to store the namenumber
puts "enter a name" #ask for...
name = gets().chomp #and get a name (chomp off the newline char)
name.upcase! #convert it to uppercase to match the table
letters = name.split('') #split it into an array of individual letters

#convert to numbers:
numbers = letters.map{ |letter| #'map' each letter to its number
number_of[letter] #using the table we made
} #now we have an array of numbers

#we may have to do the next part more than once, so start a loop
loop do
sum = 0 #start with 0
numbers.each{ |number| #for each number in the array...
sum+= number #add it to the sum
}
if sum <=9 #if the sum is one digit...
namenumber = sum # it is our final number
break # so break out of the loop
else #otherwise
digits = sum.to_s.split('') # split the number into single digits
numbers = digits.map{|digit| # map each text digit
number_of[digit] #to it's actual number,
} #updating the array of numbers
end
end #end of loop, go back to loop start

puts "The number of #{name} is #{namenumber}" #show result

Hi,

I am planning to implement a Numerology code like this.

Every alphabet in Numerology is given a number like this...

--------------------------------------------------------------
1 2 3 4 5 6 7 8 9

A B C D E F G H I

J K L M N O P Q R

S T U V W X Y Z
----------------------------------------------------------

Or you can even say that

1 = A, J, S
2 = B, K, T
3 = C, L, U
4 = D, M, V
5 = E, N, W
6 = F, O, X
7 = G, P, Y
8 = H, Q, Z
9 = I, R

Now when you type RUBY you should get the total as 9+3+2+7 = (21) 2+1 =
3
where R = 9, U = 3, B = 2 and y = 7 ( as shown above )

golfing solution...

'HELLO'.unpack('C*').inject(0){|s, b|s+(b-65)%9}

I get 20 for that, but every result should be a single digit.

So 'IRREVERSIBLE' should result in 4, I suppose. In any case, I
missed the part about adding the individual numerological digits
together.

I guess I should have checked wikipedia.

thx for correction,
Todd
