Feel free to reach out to us for further information. It has the competency to allocate breakpoints to debug code. Also, you can opt for Aptana Studio that provides integrated support with Rails.

It comprises tree-structured code representation and can easily inspect variables, and control execution. Yes, there is a difference between Ruby and Ruby on Rails. Ruby is a language while Ruby on Rails is a web framework. Ruby is a dynamic, object-oriented, interpreted scripting language.

While, Ruby on Rails is an open-source web application framework, which functions on Ruby language. Jet Brains is one the leading and familiar programming language development tools name. RubyMine works well with most of the major frameworks such as Ruby 2.

It also provides seamless support for front end technology development. It also provides support for code refraction, debugging and unit testing.

Its popularity is mainly among the developers who love to use the keyboard no mouse for lightning fast coding.

Its popularity is known from the fact that many engineers at Facebook have used VIM during the early development of Facebook itself. VIM is known as one of the most feature rich free text editor. Users can easily convert it into a powerful Ruby development environment through right customization and configuration.

There are also some plugins like vim-ruby for Ruby Scripting and vim-rails for Ruby on Rails web development. It is available as open source and free to use for Ruby development.

There are various plugins available that users can use to transform the text editor into a full featured Sublime IDE for Ruby programming. It offers IDE for almost every programming languages that also includes Ruby. Cloud9 is becoming very popular among medium to large enterprises very fast.

Many companies such as Heroku , Soundcloud , Mailchimp and Mozilla are some of the popular users that are already using Cloud9. Users can easily access the commands in the Cloud9 development environment for Ruby on Rails. User will have to just open the command and then type the program name following ruby. The system could make its best guess on what to do, and one of us could fix it if it was wrong. In theory, this seems like a terrible idea that could never work.

In practice, it mostly does work. So how does this work in practice? The system doesn't need to be right, it just has to be consistent, and it needs to try to keep your intent. The image below shows this. If I type in the word "hello," the system should do its very best to make sure "hello" ends up in the document somewhere.

That is intent. And if someone else types "bye" at the same spot at the same time? Our two documents should eventually end up exactly the same, whether that is "hellobye" or "byehello" — the documents need to be consistent. What about conflicts? Well, people are kind of natural conflict resolution machines. If you are walking down the hallway, and someone is about to walk into you, you will stop.

Probably both of you will move to the same side. And then maybe you will both move to the other side and you will laugh. But then eventually one of you will move, and the other will stand still, and everything will work out.

So, you want your editor to quickly respond to the person using it. If you are typing, you do not want to wait for a network request before you can see what you typed. And you want the other people editing your document to see your changes. And you want to do all of this as fast as possible. How could you make that work?

The first thing you might think of is sending diffs, like the image below. All diffs do is tell you what changed, not why. You can make these actions or operations pretty much whatever you want. Everything from "insert some text" to "make this section of text bold. So, as you can see below, applying this operation changes "Hello" to "Hello, world.

If we have operations, and we can send operations, and we can change documents by applying operations, then we almost have collaboration.

Client B could apply that operation, and you would have the same doc! Bingo — job is finished and it is perfect. Except it is not. Because remember — you could both be changing the document at the same time.

So, let's say you have two clients. They each have a document with the text "at" as shown below. Now, the left client types "c" at position 0, making the word "cat. Now, the client on the right gets this "insert c at 0" operation from the other client and ends up with "cart. But then the client on the left gets the "insert r at 1" operation from the other client, ending up with the "crat" you see below.

Worse than the unknown "crat," we have violated one of our most important rules. Both documents need to be consistent with one another — they need to end up at the same state. Because now, if the client on the left deletes the character "a" after position 2, it also deletes "r" on this other client without having any idea that it is doing it. It is wrong and broken in a way a person cannot fix. So let's look at the problem again.

We have two operations that happen at the same time, meaning they both came from the same document state — the "at" example we talked about earlier. Whenever we have two operations that happen on the same exact document, that means we might need to change one of them. This is because you can only make changes one after the other, in order — like we just saw with "cart" and "crat," order matters.

On this client, it means that the insert "r" has to change so that it can happen after the insert "c. Well, after you insert "c," the old position 1 highlighted in yellow below is now position 2. Everything moved over by one.

If the "r" goes in between "a" and "t" just like it did over on the other client , it should go into position 2 — right? So, when you get that "insert r at 1," you transform it into "insert r at 2" before you apply it.

How about on the other side? It gets "insert c at 0. What you are trying to do is say, "If operation A and operation B happened at the same time, how could I change operation B to adjust for what operation A did?

That can sometimes be abstract and hard to think about. So I draw boxes instead. Yep, I have lots of pieces of paper filled with boxes. But check this out below. In the upper-left corner, I write a document state — "at. I draw an arrow going right and I write one of the operations "insert c at 0" on it.

Then in the upper-right, I write what things look like after that happens "cat". Then I draw a line going down. Next, I draw an arrow going down. This one gets the other operation "insert r at 1". Same as before: I write down what things look like after that happens "art". And I draw an arrow going right. We end up with what you see below. Now we have a decision to make. In the lower right-hand corner, what should the document look like? This is where thinking about what your user would expect can help, but sometimes you have to just make a decision.

Here, though, the answer is not ambiguous — it should be "cart. Those two arrows are our two transformed operations. Once you know this, it is really easy to test drive the code that transforms your operations. The top and left sides are your inputs, and the right and bottom sides are your expected outputs. There is one last problem to solve before we can start writing these, though.

How do you break ties? If both clients are trying to insert the text in the exact same place, whose text ends up first? Remember — you do not have to be right, you just have to be consistent. So, pick a consistent tiebreaker. If you are communicating with a server, you can decide that the server always wins. Or you can give every client a random ID, and the biggest one wins.

Just be consistent. We have some operations to transform and some expected return values. What would this transformation function actually look like? It transforms top against left to get the bottom arrow, then left against top to get the right arrow, and then returns both of them, which completes our square. But that is just punting the question. How do you transform that left operation so it acts as if it happened after the top operation shifts everything over and becomes that right arrow — "insert r at 1"?

We write a to-do for later. Next, we return a new operation because we do not want to mess anything up by changing the one that was passed to us. In the if line, we answer the question: What would cause our position to change? If the other client is inserting text before our spot, we will need to move over. And if they are inserting text at the same spot as us, and we lose the tiebreaker, we will also have to move over.
