The Rails Playground is widely open now, let’s see when it lands ;-)

The most unique thing to say about it, is the ability to host unlimited number of Rails applications on ONE (yes, ONE as 1) Mongrel instance. Without this trick, there would never be a way for the Playground to even exist.

Oh, and yes, it has the best online source code editor for Ruby/Rails available, but that’s just a secondary effect :).

Give it a try! And be nice and leave some feedback (any kind of it is more than welcome, negative thoughts help as well).

Enjoy! :-)

*.isonrails.com is the Rails Playground project I have been solely working on since .. well, if you know Amy Editor - it was meant to be just a small part of it and main reason it all started.

I’m happy to announce, that after presenting the Playground on EURUKO 2008 Conference, it is now available for joining in.

The project is aimed to starting Rails developers or anyone wishing to just give Rails a try in few seconds without configuring and installing anything on her computer. All you need is a decent browser (Safari, Firefox, even Opera or Internet Explorer will do). No Ruby, no Rails, no gems, no setup.

Do not hesitate and give it a try! :)

P.S. - the project is currently in invitation phase meaning you simply request for invitation, we confirm it and you’ll be able to hop in. This is meant to be just a temporary, it will later be open to registrations without invitations to anyone.

Licensing terms: MIT license, do whatever you want with it :).

Any questions, problems installing/running, anything else - please, just visit the forum and ask. Or write a comment below.

Stay tuned, bigger announcement coming soon :-)!

More on the topic later, heading for a floorball game (play, not to watch:).

As always, stay tuned for more updates.

There’s a little screencast demo you can watch. It’s not very good movie-wise, but it’s viewable :-). It’s pretty hard and time consuming to create a good one. I just don’t have patience for that ;).

This post is just an initial kick-off to assure anyone interested, that Amy Editor is not a dead project, even though I haven’t been able to post about it lately. It’s under active development, with several missing/experimental/not quite finished features. Please take it as a development version for now and be patient if something’s wrong. I’m out of job babysitting my two little boys during day and hacking over nights. And very tired right now actually :).

Project in general is a collection of resources (for now documents if you will) provided by third parties (such as your company, your fellow developers website and such) that is accessible to you.

Each project has its own unique URL address, pretty much like any standard web page. If you want to open a project, all you need is such URL. Optionally the project can contain several parameters for you to adjust. Eg. FTP Editor project requires the login credentials along with ftp address itself (so do DAV and Blog editors).

There are currently four projects available to you:

• Playground
  
  
  URL: http://www.april-child.com/amy/projects/playground.php
  
  
  It’s the simpliest of projects, purposed for those who just want to play with Amy for the first time. Contents are stored on Amy server and are generally accessible.
• DAV Editor
  
  
  URL: http://www.april-child.com/amy/projects/dav.php
  
  
  Access webdav resources. If you happen to have WebDAV access (that is accessible from internet), you may access it and actually open documents in Amy.
• FTP Editor
  
  
  URL: http://www.april-child.com/amy/projects/ftp.php
  
  
  The same as DAV, except for any FTP server. Do you have a website hosted and want to be able to access its contents from anywhere using just your browser and comfortable editor? This
  
  might be the way.
• Blog
  
  
  URL: http://www.april-child.com/amy/projects/blog.php
  
  
  Use this project for accessing your blog contents. It serves as a generic blog editation tool. Currently supported is the MovableType API, works fine with any Wordpress, other systems are currently not tested (and for simplicity won’t work due lack of blogID parameter), but this will eventually change for full blog API support including those of Blogger.

The “project feature” itself is controlled by its own API, so it’s fairly easy to create your own unique project taking documents from your application and allow access (restricted, limited, …) to fellow developers/collaborators all via Amy. There is no need to let authentication slip past your fingers, you may as well do it yourself and still be able to create a project. The API will be presented soon (or you may mail me for additional info). There are libraries/plugins for Ruby on Rails and PHP5 at the moment.

What’s it about?

Fry Framework (or just Fry) is an evolution of 12 years JavaScript programming (mine of course, not in general:-). Long time has passed and the framework encapsulates many ideas being discovered on the way. I’m not going to bore you with more historical/philosophical views, let’s just start right away. Well, keep reading…

Prerequisities

You should be somehow familiar with the idea of DOM. If you’ve never used document.getElementById(), node.appendChild(el) and similar, this is probably not for you. Don’t be sorry though, there are millions of things more worthy than being a javascript weirdo:-).

No more .appendChild()

Fry is based around idea of replacing the most tedious code writing. It frees you from tons of “fill the gap” code for performing trivial DOM manipulation, assigning and responsing to various events, dealing with XML, Ajax and file uploads. Your code will be much smaller, written in a fraction of time. You may use the time saved for the real problems or just go home :-).

Learn the shortcuts, keep the chain in mind

You were probably looking for the first example, here it goes:

$().a($$()).t(‘Hello world!’).e(‘click’, function(evt)
{
	evt.$.s(‘color:red’).at(‘ This is Fry.’);
});

Although a little bit cryptical at first, believe me, you will get used to it very quickly. What we just wrote is a DIV appended to BODY containing the text “Hello world!” that is clickable. After you click on it, it will change its text color to red and append the text “This is Fry.”. Maybe you will better recognize this piece of code:

var el = document.createElement(’DIV’);
// yes, I know we should be doing true DOM using el.appendChild(document.createTextNode(’Hello world!’)),
// but is the phrase “developers cycle” saying anything to you? :-)
el.innerHTML = ‘Hello world!’;
el = document.getElementsByTagName(’BODY’).item(0).appendChild(el);
// This will not work for IE, we should use attachEvent()
el.addEventListener(’click’, function(evt)
{
	el.style.color = ‘red’;
	// or var ht = el.innerHTML; ht += ‘ This is Fry.’; el.innerHTML = ht;
	el.appendChild(document.createTextNode(‘ This is Fry.’));
});

OK, this was not fun, first we have to deal with browser differences, secondly there is just too much code to be written and we only scratch the surface with a primitive task. Don’t write your code this way. You may not end up using Fry, feel free to use Prototype, Mochikit, JQuery or any of the zillions of frameworks. Let me repeat it. Do NOT, under any circumstances, try to write your code this way, that is using the primitives of DOM. Unless of course you’re a regular to S&M parties and pain is your pleasure :-).

Learn the shortcuts and commands chaining

Apart from previous chapter title, we haven’t quite talk about it yet. So what are these shortcuts and what the hell is chaining anyway? Does it do any good to me or will I be forced to rethink and shift my programming techniques? Well, the answer to the last two questions is simple. Yes and .. probably yes. First answer is just a reassurement, you will have to find the real answer to the second question by yourself. Enough of this chit-chat already…

Shortcuts are methods names shortened to absolute minimum. If you want to positionate something on your page at 400 pixels from the left and 140 from the top of your browser window, you just imagine the more natural X and Y coordinates (left for X, top for Y) and write el.x(400).y(140). It’s that simple. Chaining is what you just saw. Practically any method combination can be used to archieve something on an element/object. You just have to separate the methods by dot. So instead of writing several lines of code, you can archieve the same effect by chaining. And since you use shortcuts, the lines are not very long thus easily readable. If you don’t understand:

	el.x(314).y(159).z(26).t(‘hello from chain’);
	// does it need a comment? positionate el 314 left, 159 top, z-index 26,
	// and let it contain the text “hello from chain”	

then again, Fry is probably not for you.

You know, Fry… Of all the friends I’ve had, you’re the first

This was just an introductory article to Fry. Stay tuned.

I really have to change Wordpress to something else… It’s ugly in the morning.
