One of the advantages of learning a new language is being exposed to new idioms and new approaches to solving old problems. In this talk, we will introduce the Ruby language with particular focus on the idioms and concepts that are different from what is found in Java.
We will introduce concepts such as closures, continuations and meta programming. We will also examine powerful techniques that are practically impossible in Java due to its compile time binding of types.
No experience with Ruby is assumed although an understanding of Java would be helpful.

Ruby is a fully object-oriented programming language where everything is an object. It uses modules to group classes and symbols to name variables and methods. Ruby code is written in blocks delimited by keywords like 'if' and 'end'. An example program demonstrates how a Person class in Ruby compares to a similar class in Java, using object instantiation, attributes, and a method. Key differences between Ruby and Java include Ruby being dynamically typed, using '# ' for comments, and 'attr_accessor' for getters and setters.
This document provides an overview of the JavaScript programming language, including its history, key concepts, values, objects, and functions. It summarizes JavaScript as a dynamic language that unifies objects and functions, uses prototype-based inheritance, and loosely typed values. Everything in JavaScript is an object, which can be used to represent records, trees, and other data structures using dynamic object literals.

Ruby is a dynamically typed, object-oriented scripting language that is interpreted. It was created by Yukihiro Matsumoto in 1995 and influenced by Smalltalk, Perl, Lisp and Python. Some key features of Ruby include being garbage collected, supporting inheritance and mixins, and being suitable for meta-programming. It gained popularity through frameworks like Ruby on Rails. The core data types in Ruby are implemented as objects and include integers, floats, strings, arrays, hashes, symbols, booleans and nil. Classes and modules provide namespaces and support object-oriented programming principles like inheritance. Ruby supports functional programming patterns through blocks, procs and lambdas.
This document provides an overview of Ruby for Java developers, covering the history and culture of both languages, their technical backgrounds, key differences in their languages and frameworks, and how Ruby on Rails works. It demonstrates Ruby concepts through examples and concludes with a discussion on performance and common use cases for each language.
This document provides an agenda and notes for a talk on optimizing Scala code to solve real-world problems without explosions, broken thumbs, or bullet wounds. The agenda includes discussing mantras, collection functions, implicits, and style. It emphasizes writing expressions instead of statements, avoiding null, staying immutable, using options instead of null checks, and limiting the scope of implicits. It also covers collection functions, type classes, and breaking out of for-comprehensions. The overall message is to write clear, concise Scala code using best practices around expressions, immutability, and type safety.

Java is an object-oriented programming language developed by Sun Microsystems to be small, simple, and portable across platforms. It uses classes and objects, inheritance, interfaces, and packages. A class is a template that defines objects, which are instances of a class. Inheritance allows classes to inherit attributes and behaviors from parent classes. Interfaces define behaviors without implementations. Packages organize related classes.
- The document discusses Ruby meta programming and provides information about the author such as their Twitter handle and blog. It then covers topics like what Ruby is, differences between Ruby and other languages, and new concepts in Ruby like symbols, variables, and object-oriented principles.
You have probably noticed the excitement regarding functional programming and the new lambda expression in Java 8. But did you know that this also brings Java back to its object-oriented roots?
The Smalltalk programming language shows how virtually any task can be achieved through good old object orientation. Everything is built with the basic ingredients of objects, messages and blocks (lambda).
Smalltalk uses lambda expressions for conditional processing, iteration and exception handling. We will look at some fascinating examples, and discuss if and how to apply them in Java.
We Java programmers now find ourselves with a brand new lambda tool in our toolbox. Lets take the time to learn from the past about the power of object orientation and lambdas.

This document provides an overview of key Ruby object-oriented programming concepts including:
1) Ruby objects consist of a reference to their class, instance variables, and flags. Ruby classes are also objects that consist of a reference to their superclass, instance variables, methods, and flags.
2) Classes inherit behavior from other classes and encapsulate an object's state within instance variables and methods. Polymorphism allows different objects to respond to the same message.
3) Modules are used as namespaces and mixins to enhance classes. The Kernel module mixes instance methods into Object to define core functionality for all objects.
4) Ruby uses various variable types including instance variables (@), class variables (@@), local
String is a non-primitive and immutable data type in Java that represents a sequence of characters. It is stored in the String Constant Pool in the heap memory. Methods like equals(), concat(), contains(), indexOf() etc. are used to perform operations on strings. String is immutable to prevent unexpected behavior if the contents of a string are changed.
Ruby allows metaprogramming through dynamically modifying program constructs at runtime. This includes defining classes and methods dynamically, adding methods to existing classes and objects, and manipulating language semantics. Some key Ruby metaprogramming techniques are open classes/monkey patching, method_missing, define_method, eval, and hook methods. Metaprogramming can help write domain-specific languages and validation macros, but comes with costs like a steeper learning curve and reduced comprehensibility.

In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.
Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved.
The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring.
The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise.
By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development. We’ll not only delve into the technical aspects of AI-powered XML development but also discuss practical implications and possible future directions.
2. About the Section
• Introduce the Ruby programming language
• Basic understanding of ruby
3. What is Ruby?
• Programming Language
• Object-oriented
• Interpreted
4. Ruby Introduction
• Ruby originated in Japan during the mid-1990s
• Ruby is Based on Perl,Smalltalk,Eiffel,Ada and Lisp.
• Ruby offers automatic memory management.
• Ruby is Written in c
• Ruby is a dynamic interpreted language which has many
strong features of various languages.
• It is a strong Object oriented programming language.
Ruby is open source
• Ruby can be embeded into Hypertext Markup Language (HTML).
• Ruby has similar syntax to that of many programming languages such as
C++ and Perl.
5. Interpreted Languages
• Not compiled like Java
• Code is written and then directly executed by
an interpreter
• Type commands into interpreter and see
immediate results

• Development framework for web applications
written in Ruby
• Used by some of your favorite sites!
7. Advantages of a framework
• Standard features/functionality are built-in
• Predictable application organization
– Easier to maintain
– Easier to get things going
8. Installation
• Mac/Linux
– Probably already on your computer
– OS X 10.4 ships with broken Ruby! Go here…

9. RVM
Before any other step install mpapis public key (might need gpg2) (see
security)
gpg --keyserver hkp://keys.gnupg.net --recv-keys
409B6B1796C275462A1703113804BB82D39DC0E3
curl -sSL https://get.rvm.io | bash -s stable --ruby
11. puts vs. print
• "puts" adds a new line after it is done
– analogous System.out.println()
• "print" does not add a new line
– analogous to System.out.print()
12. Running Ruby Programs
• Use the Ruby interpreter
ruby hello_world.rb
– “ruby” tells the computer to use the Ruby
interpreter
• Interactive Ruby (irb) console
irb
– Get immediate feedback
– Test Ruby features
13. Comments
# this is a single line comment
=begin
this is a multiline comment
nothing in here will be part of the code
=end
14. Variables
• Declaration – No need to declare a "type"
• Assignment – same as in Java
• Example:
x = "hello world" # String
y = 3 # Fixnum
z = 4.5 # Float
r = 1..10 # Range
15. Objects
• Everything is an object.
– Common Types (Classes): Numbers, Strings, Ranges
– nil, Ruby's equivalent of null is also an object
• Uses "dot-notation" like Java objects
• You can find the class of any variable
x = "hello"
x.class → String
• You can find the methods of any variable or class
x = "hello"
x.methods
String.methods
16. Objects (cont.)
• There are many methods that all Objects have
• Include the "?" in the method names, it is a
Ruby naming convention for boolean methods
• nil?
• eql?/equal?
• ==, !=, ===
• instance_of?
• is_a?
• to_s
17. Ruby defined? operators:
defined? is a special operator that takes the form of a method call to determine
whether or not the passed expression is defined.It returns a description string
of the expression, or nil if the expression isn't defined.
There are various usage of defined? Operator:
Example
foo = 42
defined? foo # => "local-variable"
defined? $_ # => "global-variable"
defined? bar # => nil (undefined)
20. Operators and Logic
• Same as Java
– Multiplication, division, addition, subtraction, etc.
• Also same as Java AND Python (WHA?!)
– "and" and "or" as well as "&&" and "||"
• Strange things happen with Strings
– String concatenation (+)
– String multiplication (*)
• Case and Point: There are many ways to solve
a problem in Ruby
21. if/elsif/else/end
• Must use "elsif" instead of "else if"
• Notice use of "end". It replaces closing curly
braces in Java
• Example:
if (age < 35)
puts "young whipper-snapper"
elsif (age < 105)
puts "80 is the new 30!"
else
puts "wow… gratz..."
end
22. Inline "if" statements
• Original if-statement
if age < 105
puts "don't worry, you are still young"
end
• Inline if-statement
puts "don't worry, you are still young" if age < 105
23. for-loops
• for-loops can use ranges
• Example 1:
for i in 1..10
puts i
end
• Can also use blocks (covered next week)
3.times do
puts "Ryan! "
end
24. for-loops and ranges
• You may need a more advanced range for
your for-loop
• Bounds of a range can be expressions
• Example:
for i in 1..(2*5)
puts i
end
25. while-loops
• Can also use blocks (next week)
• Cannot use "i++"
• Example:
i = 0
while i < 5
puts i
i = i + 1
end
26. unless
• "unless" is the logical opposite of "if"
• Example:
unless (age >= 105) # if (age < 105)
puts "young."
else
puts "old."
end
27. until
• Similarly, "until" is the logical opposite of
"while"
• Can specify a condition to have the loop stop
(instead of continuing)
• Example
i = 0
until (i >= 5) # while (i < 5), parenthesis not required
puts I
i = i + 1
end
29. Parameters
• No class/type required, just name them!
• Example:
def cumulative_sum(num1, num2)
sum = 0
for i in num1..num2
sum = sum + i
end
return sum
end
# call the method and print the result
puts(cumulative_sum(1,5))
30. Return
• Ruby methods return the value of the last
statement in the method, so…
def add(num1, num2)
sum = num1 + num2
return sum
end
can become
def add(num1, num2)
num1 + num2
end
31. User Input
• "gets" method obtains input from a user
• Example
name = gets
puts "hello " + name + "!"
• Use chomp to get rid of the extra line
puts "hello" + name.chomp + "!"
• chomp removes trailing new lines
32. Changing types
• You may want to treat a String a number or a
number as a String
• to_i – converts to an integer (FixNum)
• to_f – converts a String to a Float
• to_s – converts a number to a String
• Examples
"3.5".to_i → 3
"3.5".to_f → 3.5
3.to_s → "3"
33. Constants
• In Ruby, constants begin with an Uppercase
• They should be assigned a value at most once
• This is why local variables begin with a
lowercase
• Example:
Width = 5
def square
puts ("*" * Width + "n") * Width
end
34. Ruby Blocks
✓ You have seen how Ruby defines methods where you can put
number of statements and then you call that method. Similarly
Ruby has a concept of Block.
✓ A block consists of chunks of code.
✓ You assign a name to a block.
✓ The code in the block is always enclosed within braces ({}).
✓ A block is always invoked from a function with the same name
as that of the block. This means that if you have a block with the
name test, then you use the function test to invoke this block.
✓ You invoke a block by using the yield statement.
35. Syntax:
block_name{
statement1
statement2
..........
}
Here you will learn to invoke a block by using a simple yield
statement. You will also learn to use a yield statement with
parameters for invoking a block. You will check the sample
code with both types of yield statements.
36. The yield Statement:
Let us look at an example of the yield statement:
def test
puts "You are in the method"
yield
puts "You are again back to the method"
yield
end
test {puts "You are in the block"}
This will produce following result:
You are in the method
You are in the block
You are again back to the method
You are in the block
37. You also can pass parameters with the yield statement. Here is an
example:
def test
yield 5
puts "You are in the method test"
yield 100
end
test {|i| puts "You are in the block #{i}"}
This will produce following result:
You are in the block 5
You are in the method test
You are in the block 100
Here the yield statement is written followed by parameters. You can
even pass more than one parameter. In the block, you place a
variable between two vertical lines (||) to accept the parameters.
Therefore, in the preceding code, the yield 5 statement passes the
value 5 as a parameter to the test block.
38. Variables in a Ruby Class:
Ruby provides four types of variables:
1.Local Variables: Local variables are the variables that
are defined in a method. Local variables are not available outside
the method. You will see more detail about method in subsequent
chapter. Local variables begin with a lowercase letter or _.
2.Instance Variables: Instance variables are available
across methods for any particular instance or object. That means
that instance variables change from object to object. Instance
variables are preceded by the at sign (@) followed by the variable
name.
3. Class Variables: Class variables are available across
different objects. A class variable belongs to the class and is a
characteristic of a class. They are preceded by the sign @@ and are
followed by the variable name.
39. 4.Global Variables: Class variables are not available
across classes. If you want to have a single variable, which is
available across classes, you need to define a global variable.
The global variables are always preceded by the dollar sign ($).
Variables in a Ruby Class:
40. Ruby Classes & Objects
class Customer
@@no_of_customers=0
def initialize(id, name, addr)
@cust_id=id
@cust_name=name
@cust_addr=addr
end
def display_details()
puts "Customer id #@cust_id"
puts "Customer name #@cust_name"
puts "Customer address #@cust_addr"
end
def total_no_of_customers()
@@no_of_customers += 1
puts "Total number of customers: #@@no_of_customers"
end
end
# Create Objects
cust1=Customer.new("1", "John", "Wisdom Apartments, Ludhiya")
cust2=Customer.new("2", "Poul", "New Empire road, Khandala")
41. Flow of Code
# Call Methods
cust1.display_details()
cust1.total_no_of_customers()
cust2.display_details()
cust2.total_no_of_customers()
Customer id 1
Customer name John
Customer address Wisdom Apartments, Ludhiya
Total number of customers: 1
Customer id 2
Customer name Poul
Customer address New Empire road, Khandala
Total number of customers: 2
42. ✓ Inheritance is a relation between two classes.
✓ Inheritance is indicated with <.
class Mammal
def breathe
puts "inhale and exhale"
end
end
class Cat < Mammal
def speak
puts "Meow"
end
end
rani = Cat.new
rani.breathe
rani.speak
Inheritance
43. Features of Ruby
✓ Object-Oriented
✓ Portable
✓ Automatic Memory-Management (garbage collection)
✓ Easy And Clear Syntax
✓ Case Sensitive
Lowercase letters and uppercase letters are distinct. The
keyword end, for example, is completely different from the
keyword END. and features
44. ✓Statement Delimiters
Multiple statements on one line must be separated by semicolons,
but they are not required at the end of a line; a linefeed is
treated like a semicolon.
✓ Keywords
Also known as reserved words in Ruby typically cannot be
used for other purposes.
A dynamic, open source programming language
with a focus on simplicity and productivity
✓ Open Source
