+Ruby adalah sebuah bahasa pemrograman dari Jepang yang merevolusi
+dunia pengembangan software.
+
+Keindahan dari Ruby terletak pada keseimbangan antara kesederhanaan dan kekuatannya.
+
+Kamu bisa coba mengetik beberapa kode Ruby di editor dan gunakan tombol-tombol berikut untuk navigasi:
+
+- __Run__ → Mengeksekusi kode yang ada di editor
+- __Copy__ → Menyalin contoh kode kedalam editor
+- __Next__ → Melanjutkan ke pelajaran selanjutnya
+- __Back__ → Kembali ke pelajaran sebelumnya
+- __Clear__ → Mengosongkan editor
+
+Gunakan tombol dengan ikon 'dunia'
+diatas untuk merubah bahasa TryRuby.
+
+### Klik tombol __Next__ untuk mulai belajar.

+
+You can't reverse the number forty. I guess you can hold your monitor up to the mirror, but reversing a number just doesn't make sense.
+
+Ruby has tossed an error message. Ruby is telling you there is no method reverse for numbers.
+
+Maybe if you turn the number into a string first:
+
+ 40.to_s.reverse

+And numbers are different from strings.
+
+While you can use methods on any object in Ruby, some methods only work on certain types of things.
+But you can always convert between different types using Ruby's "to" methods.
+
+- __to_s__ converts things to __s__trings
+- __to_i__ converts things to __i__ntegers (numbers)
+- __to_a__ converts things to __a__rrays
+
+__What are arrays?!__
+
+They are lists. Type in a pair of brackets:

+ []

+
+You've hung on to your lotto numbers, tucking them away inside a __variable__ called ticket.
+But any other name, like _jimmyslist_, would have been fine too.
+
+Programming, you will discover, is mostly about working with variables.
+
+Let's put your lotto numbers in order, how about?
+
+Use:
+
+ ticket.sort!
+
+You had a list. You sorted the list. The ticket variable is now changed.
+Did you notice that the _sort!_ method has a big, bright exclamation at the end?
+A lot of times Ruby methods shout like that if they alter the variable for good.

+answer: ^(12|35|47)$
+load: ticket = [12, 47, 35]
+ok: Ok
+error: Almost
+---
+
+So we stored our lotto numbers inside variable ticket. How to get 'em out again?
+
+We already saw that we can get the highest number with __max__. Similarly you can
+get the __first__ or the __last__ element of the list.
+But what if you want a specific element?
+
+### [ ]
+Ruby uses the square brackets [ ] to target an element.
+The square brackets are very common in Ruby.
+They are like sights used to line up a target. Exactly.
+These brackets mean, "I am looking for ____" Ready, aim.
+
+Let's get all of our lotto numbers:
+
+ puts ticket[0]
+ puts ticket[1]
+ puts ticket[2]
+
+Why do we use [0], [1], [2]?
+
+And not [1], [2] and [3]? Is that some kind of Japanese Zen thing?
+No, we computer people just like to begin counting from zero. It's not just a Ruby thing,
+this _zero based indexing_ is used in most programming languages.
+
+> A little reminder: you can use the __Copy__ button to copy the example code to the editor.

+error:

+
+One other little thing we haven't really talked about openly: method arguments.
+Remember when we changed the poem a little bit? We used:
+__poem.gsub("toast", "honeydew")__
+
+The gsub method needs 2 arguments, which we passed to gsub by including two strings between
+parenthesis. _Arguments tell the method exactly what to do._
+
+### Parenthesis
+Actually, most of the time Ruby doesn't mind if you omit the parenthesis. So this would have
+worked too:
+__poem.gsub "toast", "honeydew"__
+
+We have already used another method with a parameter. Many times in fact, though it was not very
+obvious:
+
+ puts "Hello"
+ puts("Hello")
+
+Yes __puts__ is also a method. Using puts with or without parenthesis is the same to Ruby, but the
+version without parenthesis is a bit easier to read. And it saves you valuable typing time!
+
+> So I guess the conclusion is that you can do whatever you like with parenthesis as long as your
+> code reads nicely.
+
+### to (be) or not to (be)
+So if _to_ is a method and _be_ is an argument we now know the answer to this age old question.
+It is really just a matter of preference whether you want _to be_ or _to(be)_.
+

+answer: ^tame
+ok: Good good!
+error:
+---
+
+You totally know how to use Ruby now. I mean you've got down the essentials.
+You just need to keep learning more methods and try out more complex blocks.
+
+But there's one side of Ruby we haven't settled. Making your own methods.
+__Ahem!__ Let's get it over with then.
+
+Next to using Ruby's built in methods (like puts, sort, times) you can define
+your own methods. Why is that a good idea? Two reasons:
+
+### To make your program shorter
+If you have to do the same thing in more than one part of your code it is easier
+to put that code in a separate method. Your code will be shorter.
+
+### To make your code easier to read
+Suppose your program needs to do a lot of different things.
+You __could__ stuff all code into one long piece. But it would be very difficult to
+read and understand that code later.
+
+Instead you should cut up your code in different methods and give each method an easy to
+understand English name. You will thank yourself later.
+
+So how do we define a method? Like this:
+
+ def tame( number_of_shrews )
+ end

+you can omit the word __return__ from the last line of the method.
+Ruby will automagically return the last value that was used inside the method.
+
+So we can change the last line to just: __number\_of\_shrews__.
+
+But since method __.times__ also returns the _number\_of\_shrews_ we can
+remove the entire last line. So in fact our original method already did what we wanted all along!

+error:

+---
+
+Okay we now have a list of plays from the internet. The list was in the json format.
+Fortunately for us Ruby kindly provides a method to convert json data to a Ruby hash.
+The _get\_shakey_ method already did that for us.
+
+But since the structure of the json data is retained in the hash, it is still a bit difficult to read.
+Let us write a method to display the plays nicely.
+
+If you inspect the list of plays carefully you will see that it has a kind of nested
+structure. (This is actually quite common in data you get from the internet.)
+Looks like this:
+
+
+
"William Shakespeare"
+
+
"1"
+
+
"title": "The Two Gentlemen of Verona"
+
"finished": 1591
+
+
+
"2"
+
+
"title": "The Taming of the Shrew"
+
"finished": 1591
+
+
+
...
+
+
+
+
+To list the plays we first have to access the top "William Shakespeare" hash element by it's name.
+Next we have to __iterate__ through each element below it.
+
+Ruby has a method for iterating. It is called __each__. We have seen it before when
+creating our book rating system.
+
+Everything that method __each__ returns is passed to a block:
+
+ s = get_shakey
+
+ s["William Shakespeare"].each { |key, val|
+ puts val["title"]
+ }

+ok: Yes, Shakespeare wrote 4 plays in 1591
+error: Answer for the year 1591 should be 4
+load: prev
+---
+
+Now suppose we only want to know the names and number of plays written by Shakespeare
+in a certain year.
+
+Ruby lets us __select__ values from a hash. The select method uses a block to let us
+define what to select and returns what it found.
+
+We can then use the results returned by __select__ in the __each__ method as before by
+simply adding it after the select block. This is another example of method chaining, which we saw
+earlier when reversing a poem.
+
+I have prepared the __count\_plays__ method for you. See if you can find out how many plays
+were written by Shakespeare in the year __1591__. Try this:
+
+ def count_plays(year)
+ s = get_shakey
+
+ s["William Shakespeare"]
+ .select { |k, v|
+ v["finished"] == year
+ }.each { |key, val|
+ puts val["title"]
+ }.count
+ end
+
+ puts count_plays(0)
+
+Did you notice that I chained the count method at the end of the each method. This gives
+us a return value for the __count\_plays__ method.
+
+There is another possibility for chaining here. See that loney line __s = get_shakey__.
+You could add the __["William Shakespeare"].select { |k, v|__ at the end of get_shakey
+(no dot needed in this case).

+
+Okay, we got some data from the internet, we selected what we wanted and printed it out.
+What is left to improve? We could print the results a bit prettier. Like add the year
+and align titles and years.
+
+This means printing several values on one line. Ruby has a neat way of doing
+that. It is just like printing a string like: __puts "Hi, my name is Jimmy"__.
+But instead of the literal value _Jimmy_ we use the value of a variable.
+
+First replace __Jimmy__ with __#{}__. If Ruby sees a hash symbol # followed by a curly brace {
+it looks for a variable between the first brace and the following closing brace }.
+So we can use this: __"Hi, my name is \#{name}"__.
+
+Let's change our code a bit
+
+ def print_plays(year_from, year_to)
+ get_shakey["William Shakespeare"]
+ .select { |k, v|
+ year_from <= v["finished"] &&
+ year_to >= v["finished"]

+ puts "#{v["title"].ljust(30)} #{v["finished"]}"
+ }
+ end
+ print_plays(1600, 1605)
+
+I have added __.ljust(30)__ to the title. This way the title is _left justified_ with a minimum
+length of 30 characters so the years align nicely.
+
+See if you can change the ouput of the program so that it shows the plays like this: __1600 -> As You Like It__
+
+__All's Well That Ends Well?__ Hey we're not done yet, but the end is in sight!

+__If__ is a method that requires one parameter. That parameter can be any expression that you

+Here are a couple of expressions with their outcomes:
+

+Aha, you're here. And all in one piece. We're still going to make your app real,
+but until then, let's review, okay?
+
+### Classes
+Everything in Ruby is some kind of object. Classes explain objects, how a certain object works.
+For example, you made a few BlurbTM objects and these objects are explained in the Blurb
+class.
+In other words: you call them Blurb objects.
+You can use classes to (kinda) model real life objects.
+
+### Accessors
+Accessors are variables attached to an object which can be used __outside__ the object.
+(blurb2.time = Time.now)
+
+### Object variables
+Object variables are the same variables you're using for accessors, but __inside__ the object.
+(@time = Time.now)

+Okay, let's wrap things up, kid. Here's the last chapter of the GRIPPING epic story of Try Ruby!

+You have app entries, but no actual app.

+title: It's All About Combining
+answer: :-
+ok: Moody!
+error:
+load: prev
+---
+
+Some beautiful things can be done with the simple parts of Ruby, especially when you combine them
+together into new things.
+Here we've got an app made of a class containing another class. And, actually, Ruby really does good
+with this kind of creature. It is called object oriented programming.
+
+We have arrived at the __last programming excercise__ of TryRuby. If you want, you can add some
+more features to BlurbalizerTM.
+
+Maybe you want to print the mood as a smiley in the __show_timeline__ method. You could add
+a _moodify_ method to the BlurbTM class and then use that method in the _show\_timeline_ method:
+
+ class Blurb
+ attr_accessor :content, :time, :mood
+
+ def initialize(mood, content="")
+ @time = Time.now
+ @content = content[0..39]
+ @mood = mood
+ end
+
+ def moodify
+ if @mood == :sad
+ return ":-("
+ elsif @mood == :happy
+ return ":-)"
+ # Add other moods here
+ end
+
+ # The default mood
+ ":-|"
+ end
+ end
+
+ class Blurbalizer
+ def initialize(title)
+ @title = title
+ @blurbs = []
+ end
+
+ def add_a_blurb(mood, content)
+ @blurbs << Blurb.new(mood, content)
+ end
+
+ def show_timeline
+ puts "Blurbalizer: #{@title} has #{@blurbs.count} Blurbs"
+
+ @blurbs.sort_by { |t|
+ t.time
+ }.reverse.each { |t|
+ puts "#{t.content.ljust(40)} #{t.time}"
+ }

+This last section took a moment to wind down, to give you some pointers as to how you can use Ruby.
+
+If you enjoyed yourself, you can continue with the TryRuby Playground
+or download and install Ruby:
+ruby-lang.org
+
+Once you have Ruby installed, you can create a file, let say _my\_first\_progam.rb_, with a text
+editor, type some Ruby code and then run it by opening a command prompt and typing:
+
+ ruby my_first_progam.rb
+
+There are many (free) development tools available that combine an editor, file browser and a
+'ruby-runner'.
+
+## Celebrate
+You really deserve a double-layer cake with double-double frosting and a guy playing one of those guitars that's a double guitar.
+I mean you finished, you really did! No doubt about it, you're a __certified red-blooded smartiac!__
+
+## More info
+There are a couple of articles on this website. They can give you some pointers on where to
+go from here.
