KidsRuby (http://kidsruby.com) is a Ruby programming environment meant for kids. If what you want is just to download/install KidsRuby, please go to http://kidsruby.com/download

KidsRuby is heavily influenced by Hackety Hack (http://hackety-hack.com). In fact, you can run many of the same code samples from Hackety Hack in KidsRuby. For example:

color = ask("what is your favorite color")
if color == "blue"
  alert("you picked blue")
end

You can also use the Turtle, just like Hackety-Hack does

Turtle.start do
  background yellow
  pencolor brown
  pensize 2
  goto 30, 200
  setheading 180
  1000.times do
    forward 20
    turnleft rand(10)
    backward 10
  end
end

• Simple single file editor
• You can run the current contents of the editor
• The output appears next to the editor
• It runs a normal Ruby 1.9.2 on the code. With normal gems etc.

• Webkit-based editor - currently using Ace (http://ace.ajax.org/)
• QtRuby app - hosts webkit and provide http server to communicate with running Ruby environment
• Minitest/Minispec for testing. Yes, code must be tested
• Tutorial content is easy to create just drop HTML files on disk locally to the KidsRuby editor.
• Using a modified version of the JS library Turtlewax for the Turtle implementation https://github.com/davebalmer/turtlewax

Take note that the native compilation of qt (the line Installing qtbindings (4.6.3.4) with native extensions) can take several minutes without apparent progress ... You could run top to see cmake and cc1plus effectively in action.

First things first: Macs are getting weirder. Secondly you will most likely need to install Command Line Tools for XCode. That should solve this install_name_tool: object: Abacate malformed object For instructions go here

You won't be able to use the normal Qt install from homebrew because of some changes with Mavericks. To fix that go here. If you get any problems with cmake then run brew install cmake.

Clone the repo

bundle install

That should be it. Get coding. whip cracks

This was testing on homebrew commit d02e16c4415e41c7510442a1d58b98077e5e0ae4

You will most likely need to install Command Line Tools for XCode. That should solve this install_name_tool: object: Abacate malformed object For instructions go here

Then run...

brew install qt

for DIR in /usr/local/Cellar/qt/*/lib/*.framework; do ln -s $DIR/Headers ${DIR%%/lib/*}/include/$(basename $DIR .framework); done

Note: the above was done when I was trying the old instructions and I am not sure if this is needed.

Clone the repo

bundle install

NOTES: I had anaconda installed which was using the wrong qmake version make sure anaconda's qmake is not in the path

using Homebrew I used the qtbindings gem: https://github.com/ryanmelt/qtbindings Since I also run homebrew, I discovered that the homebrew install for Qt4 needed a little symlinking before I could run the gem install for qtbindings as described here: https://github.com/ryanmelt/qtbindings/issues#issue/14

However, since KidsRuby requires Qt 4.7, you need to use the following (thanks @clemcke for updated instructions):

cd /usr/local/Library/Formula
git checkout 83f742e /usr/local/Library/Formula/qt.rb
brew install qt
for DIR in /usr/local/Cellar/qt/*/lib/*.framework; do ln -s $DIR/Headers ${DIR%%/lib/*}/include/$(basename $DIR .framework); done
brew install cmake
bundle install

If you have already installed KidsRuby using the OSX installer, you will need to uninstall that Qt package before trying to install the qtbindings gem, or it will not build/install as described here https://github.com/ryanmelt/qtbindings/blob/master/README.txt.

The solution is to run this before attempting to install the qtbindings gem:

sudo /Developer/Tools/uninstall-qt.py

Someone please describe this procedure here.

Install git standalone
Install Ruby 1.9.2 standalone
bundle install

• correct pencolor so it works when switching color while drawing

• paste into editor (copy already works)

• update ruby4kids to include their latest lessons
• add more good stuff!

• make it easy to run pie (see what I did there? And it will only run on macs :P)
• create Shoes compatible classes (slippers?) to run Shoes example code too
