On May 28, 2009, at 10:09 PM, Joel Fernandes wrote:
1. couldn't find 'url' in the shoes manual, probably what you're
looking for is 'link'
Actually, they probably do mean url -- as in a multiple-page app like
this little demo:
class TwoPages Shoes
url '/', :mainpage
url '/other', :otherpage
def mainpage
para this is the main page...
para link(this way to the other, :click = '/other')
end
def otherpage
para this is the other page...
para link(this way to the main page, :click = '/')
end
end
Shoes.app
This stuff is in the Nobody Knows Shoes book, p. 43.
Shoes urls only work when you subclass Shoes, as I did here:
class TwoPages Shoes
then you can define different pages with urls and symbols and methods
named after those symbols.
When you just put stuff inside the Shoes.app block, you don't need to (and
can't) use urls and different pages defined that way.
So... to make this work they'd have to use a subclass of shoes, like this:
class OurApp Shoes
url '/', :index
[...stuff...]
end
Shoes.app # you always need this line, to make stuff happen
Next step -- get rid of the index line -- the index method gets called
automagically because it is assigned to the url / in the url line.
Third step -- as you said, the assignments of click handlers are taking
place in a different context than the index method; they don't work together
right at all that way. I don't know how I'd explain exactly how that works
to the students, honestly, cause I'm a little fuzzy myself, but here's how
I'd sum it up in a very simple rule:
When you're doing the thing with the pages and URLs, you've got to put
EVERYTHING for a page inside the method for that page (def index...end).
EVERYTHING. Nothing goes outside those methods, cause those methods build
all the pages of the app (in this case, the one page of the app, index.
So all those click handlers go inside the def indexend.
Final thing -- click handlers on buttons have to be actual code, not a
Shoes URL, so this line won't work:
button Go Back, :click = /
You can fix it two ways. You can make it a link:
para link(Go Back, :click = '/')
Or you can use the visit method to visit the URL, in a block of code
attached to the button:
button Go Back do
visit /
end
So a full working app with those changes -- subclass Shoes, get rid of the
call to index(), move the click handler assignments into def index...end
and fix the button so it visits the Shoes URL right -- would look like this
-- and with those four small changes, it works great!

Until the image is drawn, you can't really know `top` and `left`.
For instance, let's say you're using percentages:
Shoes.app do
o = oval :top = 50%, :left = 50%, :radius = 20
para Oval is at (#{oval.top}, #{oval.left})
end
Until we compute the window size, the coordinates can't be shown.
So, what you do is get the coordinates in the `start` block:
Shoes.app do
o = oval :top = 50%, :left = 50%, :radius = 20
start do
para Oval is at (#{oval.top}, #{oval.left})
end
end
Because the start block runs after the first paint.
It still feels like a bug, but I'm not sure if I want to recompute
every slot each time a new element is added. I will probably have
`top` and `left` and `width` and so on return exceptions if you
try to use them before the window is painted... I don't know.

Then we turned out all the lights and it got really fun. I asked them first what did they think happened that made a white light come out as a blue light when I put the gel over the front of the flashlight? (lots of theories of magical color transformation and after a few tries, I supplied to correct answer) when you mix red + green paint, what do you get? (several tries before one of them got the right answer: brown) I told them light mixes differently than paint, which we call additive color, as opposed to subtractive color. Then with the help of my two assistent we demostrated color mixing, It was way cool. Fewer setup problems this time. I had 3 extra computers set up and still ended short one and ended up once again abandoning my idea of coding demo since I gave the teacher computer to a pair of students. I ended up writing code snippets on the board and spending more time with each group of 2-3 kids helping debug syntax errors and giving little impromptu explanations of what was going on. I'm torn between how much time to spend explaining concepts (since they are always antsy to get onto the computers) and how much to let them wing it (which then is frustrating to them because they don't know the rules. Many of them seemed to have a hard time with the parameter syntax. Syntax errors that were hard for the kids : width = 40 : width = 40 :width 40 also, I don't understand: Shoes.app do backround black end - does not produce a syntax error, just a blank canvas, why? I also avoided explaining why the top,left of a star and arrow is in the middle -- seems like broken semantics to me. I think there must be an easier workflow than what we've been doing: write app in notepad++, save to desktop, double-click shoes, click open an app -- does anyone have a workflow where you can run Shoes directly from the editor? it would be nice if the shoes window with the errors had a Reload button and keystroke, likewise with the Shoes window. Also, they wondered: why is it called Shoes? At the end of the class I asked them to raise hands to answer: who thought it was fun? (about 2/3s of the class) who thought it was frustrating? (maybe 40%) who thought it was fun even though it was frustrating (about 1/3). I really don't know what impact this has, but I will forge ahead nonetheless. The teacher seems to think the lessons are great and the kids report having more fun than it looks like they are having. I do feel like about half the class is starting to get it. Not sure if that is a lot or very few after 1.5 hours of programming experience. Today I was still following my original lesson plan: http://github.com/railsbridge/teachingkids/blob/de9dc5444e4aa69de656739510353abebf625ff4/md/Ruby_Programming_and_Shoes.md I think I'll change it next week to add some interactivity, unless I veer in a different direction, since my RAD dorkboard arrived and I may switch to making an LED blink!

These are humanities, not computer science students, so they were interested in the concept of OOP and the context, but not so much in the code itself. Of course, when I showed how you can generate 100 sheep easily with a `sheep = []; 1.upto 100; sheep Sheep.new; end`, they become more interested. Games are probably prime example why OOP matters, because you really need smart objects and cannot hack everything with procedural code: cf. armies, villages, etc. in games like Age of Empires. Then one student stated: OK, now I see why the dog is there. So I knew I'm into some Shoes business for sure. In next lecture I brought the game and slowly walked thru the stages, starting from the bundled example, explaining what we're doing and why. They even forced me to export relevant steps from Git repo so they can run different stages of the game on their machines and mess it up a little bit. Seeing the excitement, I began to be quite sure that this could benefit other teachers/students as well, and found a day to polish the codebase and write the article. I think Shoes is very well suited to be the best platform for teaching programming basics. Partly thanks to it's playful nature, but more so because it brings direct, instant satisfaction.

Re: widgets attributes
Hi Emanuel,
I'm not sure that I understand your problem correctly, though...
The following code works well as I've expected.
I'm useing Windows XP with Shoes-0.r1091.
It also works well with Shoes-0.r1057.
class Shoes::Widgy Shoes::Widget
def initialize opts = {}
size = opts[:size] || 50
fill opts[:color] || yellow
rect 0, 0, size, size
end
end
Shoes.app :width = 300, :height = 300 do
w1 = widgy :left = 50, :top = 50, :color = red
w2 = widgy :left = 50, :top = 50, :color = blue, :size = 100
w2.move 100, 100
w3 = widgy
w3.left = 200
w3.top = 200
end
I think that we can use :left and :top without definition in class Widgy.
Because inherited from Shoes::Widget.
Hope it helps,
ashbb

Hi, I know Widgets are not the most cared things in shoes, but I stumbled

I have to call it with
w = widgy :top = 20, :left = 30
if I do w.move(30,30) it moves, so I start expecting it behaves like every
other elements.
but why I cannot do
w.left or w.right ?
obviously w.size works
it's a bug or I'm missing something?
A difference between 0.r1091 and 0.r1057
Hi _why et al,
The following snippet does the different behavior between with Shoes-0.r1091

With r1057: red square rotates on the spot
With r1091: red square rotates around 0-0 coordinate

Re: links in ur windoze
Hi Josh,
Do you really need to open multiple windows?
If not, the following code works well.
class Bummer Shoes
url /, :index
url /cleveland, :cleveland
url /neverland, :neverland
def index
para link(go to cleveland, :click = /cleveland)
end
def cleveland
#window :title = cleveland do
para link(go to neverland, :click = /neverland)
#end
#visit /
end
def neverland
para cherries, syrup, puppies
end
end
Shoes.app :title = bummer
But if you need to open multiple windows and send some messages between
them, the following sample might be of help.

and hey. that works. woo. I had tried a proc, but not a lambda... I
guess
that makes some sense because of the app object weirdness.
I don't think the difference between proc and lambda is significant
here. It's the fact that your actions are only defined for the main
app instance. window() creates a context that is basically a new
instance of an app. I think you could achieve what you did with your
dreaded global variable with Shoes owner() method.

Hi Brian,
I tried to run your code on my WindowsXP box with Shoes-0.r1057.
I put the mp3 files under the same directory with the code file.
You put them under '/' (root) directory?
So, my code is the following. It works well.
Shoes.app do

You need to add :autoplay = true option.

Hi fellow adventurers,
I'm running into issues with the Video element, and I don't know how much
of it is me misunderstanding the documentation and how much of it is buggy
shoes. I'm on Leopard 10.5.5 Intel running shoes r1057 (I downloaded, not
compiled).
First, this never plays my mp3:
Shoes.app do
@v = video /test1.mp3
@v.play
end
However, this does:
Shoes.app do
@v = video /test1.mp3
timer(0.01) { @v.play }
end
Does the event loop need to process before a new Video element can be
played? I saw nothing in the docs.
Also, is there no way to play more than one video/audio file at the same
time? Nothing in to docs says you can, but nothing says you cannot, either.
In any case, this never plays my second file:
Shoes.app do
@v = video /test1.mp3
timer(1) { @v.play }
@v2 = video /test2.mp3
timer(2) { @v2.play }
end
In my quest to learn shoes I planned to create a small shoes game with
moody music and sound effects, but I'm stumbling here.
Marginally related, is there a bug tracker for shoes? I can't find any
mention of one, or I would've just posted this there. Thanks all.

It seems that window() creates a new instance of a Shoes app or
something which somehow has no understanding of the app which spawned
it.
Note that if you say class Shoes without the leading :: the app
somehow ends up not knowing what url means. At least that's what I
found just now with shoes raisins (0.r1064) [i686-darwin8.9.1].
The unusual context within which the main file is executed seems to
continually be a problem. It would be nice for it to behave like a
normal person.

_why et al, I'm a little confused about this behavior: Shoes.app do button(:select) do @v = video ask_open_file [EMAIL PROTECTED] = '' end button(:play)[EMAIL PROTECTED] button(:stop)[EMAIL PROTECTED] @msg = para '' end In the case of Windows XP and Shoes-0.r970, when I select mp3 file, then the music is played well. Meanwhile, in the case of Windows Vista and Shoes-0.r970, the music isn't played... But omits '#' (executes line 4), then works well. Umm... Strange behavior or for some reason? Regards, ashbb
Re: The best way to develop our Shoes apps.
Hi Bluebie, we are his loyal fleshy unit test. :P Hahaha... that's right! (^^; Testing GUI apps is hard. Oh, I see... but... @all, In the Shoes tutorial discussion forum of RubyLearning.org. Yesterday I got a question (suggestion) about unit testing from one of the participants. Is it possible to add the unit testing functonality as the following to Shoes? - Make it possible to start a Shoes app from Ruby. (Without having to type Shoes my_app.rb; just ruby my_app.rb) As long as that is not possible, you can't really startup a Shoes app from the inside of a unit test. (You could call a Shoes app with the backticks, but then you wouldn't have a reference to the app object, I think.) How about this idea? Is it possible or impossible?

The game is definitely working, and I'd appreciate any feedback that you're willing to give. I'm also running into some slowdown issues as players get snakes that are pretty huge, and the game seems to run slower as someone keeps on playing it. If anyone can help with these issues I'd love to pull your changes :) Hey, great work! I have a few suggestions for how you can speed things up. Probably the way to make things the fastest is to draw on to an image surface. This ends up faster because you don't wind up creating a bunch of Ruby objects for every shape you draw. Basically, here's how to do it: 1. In app.rb, change `Field.new(self)` to `Field.new(image(400, 400))`. 2. In field.rb, change [EMAIL PROTECTED] black` to [EMAIL PROTECTED] #000`. That just creates a 400px by 400px image surface for you to paint on. Now, as alluded, the real reason it's running slow is because Ruby objects are piling up. All the old rectangles are still sitting around every time the snake is drawn. These need to be cleared out. (Unless you use an image surface, as shown above.) So, basically, if you stick with the technique you're using right now, you'll need to call [EMAIL PROTECTED] every time you repaint and then redraw all the shapes from there. _why Hi, I just started with shoes some days ago and I would be glad if anybody could help me about how to get the painting on an image surface to work. I tried with the following code, but it doesn't seem to do what I expected: Shoes.app do @img = image(400,400) @img.fill black animate do @img.rect 10, 10, 20, 20 end end What am I doning wrong? (I want to draw 1000s of tiny boxes / pixels per animation cycle later, so this is why I am trying to use an image surface for it.) Thanks, Erik.

A question about clipboard method
Hi all, I have a question about clipboard method. # get_from_system_clipboard.rb Shoes.app do @l = para '' every(10) do @l.replace clipboard end end get_from_system_clipboard.rb works well on my Windows XP. :) But,... # put_to_system_clipboard.rb Shoes.app do @l = para '' every(10) do clipboard = 'Chanky bacon!' @l.replace clipboard end end put_to_system_clipboard.rb displays 'Chanky bacon!' on the Shoes' app window. But, I do ctl+v on my wordpad, then don't display 'Chanky bacon!'. Umm... I'm confusing... What did I mistake or misunderstand? Anyone suggestion, please. Satoshi
