Ruby Programming Tutorial 1 - Getting Started

puts 'a:knock knock'

puts 'b:whose there'

puts 'a:who'

puts 'b:who who?'

puts 'a:who calling born(huw collingbourne)'

[LeCigouave]

Huw? Is that really a name? For humans? Welsh names are so odd.

In all sincerity, though: Ruby's a wonderful language, and I applaud all efforts to teach it. And Huw's actually a pretty cool name.

It's fun to see other people teaching ruby on Youtube! You should check out my newest videos. I'm hoping to gear them to beginner-beginner programmers. I'm taking kind of a fun approach to it.

[eternity899]

Its so much easier to write "puts" and "gets", as opposed to "cin" and "cout"...

Excuse my sarcasm.

[Bl3ssedWithACurs3]

Why is this so much easier than Java? Not that I say its better thus I find java to be much more organized and stuf... BUT THIS SEEMS SO EASY COMPARE TO WHAT I HAVE TO DO AT COLLEGE D:

[levi052594]

where do i download ruby? iv'e downloaded 2 different rubies and i can't get'em installed

[stathar]

@levi052594 same here :(

[pomfan45]

ruby is a piece of shit

[LeCigouave]

@pomfan45 You are the worst person ever to live.

[supercreeperproducti]

your fucking annoying

lol

[poojkhgf]

oh you have such a nice Posh voice. It makes me feel so common and dirty - I feel I am getting ideas above my station just listening for a minute or two.

[SapphireSteelDotCom]

At the time of writing Ruby In Steel 2 for VS2010 is in beta. On the SapphireSteel Software web site go to the Ruby In Steel Download Trial page and follow links to latest beta.

[gruntlover2]

Is there a version for Visual Studio 2010?

[WikiPeoples]

this guy has an amazing voice

[BLACKBINLATIN]

why do you charge people for a VS plug-in if we buy VS witch is all ready expensive and seein how ruby is free and open source it should come with ruby in steel with no trial period

[gruntlover2]

thumbs up if you would pay this guy to narrate your life

[gruntlover2]

for some reason i just like listening to your voice , lol

[StopNation]

can you make games with ruby?

[MrApplseed]

I would pay you just to talk to me.

[Iam4balance]

Very true, but I consider c# to be an extension of java for windows :)

[SapphireSteelDotCom]

I wouldn't say there is any "ideal" age at which to learn programming. It's really the same when learning any new skill. The best age is when you are interested in doing it. That might be anything from 8 to 80 - though most of us started somewhere in between! ;-)

[Iam4balance]

@SapphireSteelDotCom I Started When I Was 6 Years Old With Ansi C, Then C++, Java, BASIC, QBASIC, PYTHON, PHP, And Finally Now Ruby

[Fabitheclown]

@Iam4balance C# is missing ;D

[vogosvagen]

may i ask, whats the appropriate age for learning programing?

[MyRsIrl]

K added to favourites, Going to learn ruby l8ter.

[1hitthug]

@GameBreakersHD Yes, RPG Maker VX and RPG Maker XP are Ruby.

[Aggregate02]

I have a question concerning assigning a float value to a variable. For example, I want to assign x to the number of Pi I get a warning when I run the program: "Float 3.14 out of range." Is there a way to fix this?

[Aggregate02]

To run Ruby in Steel, you need to have Visual Basic or Visual Studio installed in your computer?

[SapphireSteelDotCom]

@Aggregate02 @Aggregate02 Ruby In Steel runs in Visual Studio. This can either be a commercial version or a free version (called the Shell Edition, which is completely legitimate and is provided free by Microsoft to third-party software developers). You can download either the normal edition of Ruby In Steel to install into a regular copy of VS or the all-in-one version of Ruby In Steel complete with the VS Shell from the SapphireSteel Software web site

[SapphireSteelDotCom]

I think Ruby is a pretty nice language to get started with. But bear in mind it will let you "get away" with things that a C-like (or Pascal-like) language won't. So be prepared to carry on the learning process when you move to a different language.

[R1DDL3RS]

I am using Ruby (not your version) when I try to open my file using:

def saystuff puts "Hello World"

Although as stated in your book, when I navigate to my .rb document it will open a new Command Prompt called something like "ruby bin" and then closes quickly. How do I open the file because I get an error message when installing Ruby in Steel

[Aggregate02]

The reason why it closes quickly is because you have to tell the program to output "Hello World" on the screen and pause. I don't know what is the approach for this, but try running it on the command prompt located in Programs -> Accessories or open Run and type in "cmd" Hope that works for you.

[SenoreQueso]

@SapphireSteelDotCom What if we're starting with Ruby, with an ultimate goal to end up in Java. Both are supposed to rather similar, right? Given Java has a much more strict syntax.

[SapphireSteelDotCom]

@SenoreQueso You can certainly learn the principles of programming with Ruby and later apply those principles to Java. The syntax of the two languages is very different, however. Also the libraries that supply much of the functionality are substantially different. Then again, my first language (many, many years ago!) was Pascal. Since then I've programmed in everything from Smalltalk to C#. These languages are all very different but the principles of good coding aren't.

[scrotos101]

Would Ruby be a good starting point to learn as a your first language and then move on to Java?

[Hitzification]

Either Ruby or Python. I began with Python. I found the syntax in Python to be more natural, but they are both great starting points.

[R1DDL3RS]

Im learning ruby and Java is handy for coding html5 canvas ect

[MsSomeonenew]

In essence, if you understand one you understand the others, I went from c++ to ruby in 1 good tutorial, few hours, all you really need to remember are the little diferences between languages, but in essence they were made to be very similar, for a quick transition between them.

[ImAllFact]

Im learning java and python and im gonna try ruby sooner or later. Lately ive been seeing a relative decline in java and python, while ruby job opportunities are growing at break-neck speed.
