Etoys

Etoys running on the OLPC display

Squeak Etoys was inspired by LOGO, PARC-Smalltalk, Hypercard, and starLOGO. It is a media-rich authoring environment with a simple powerful scripted object model for many kinds of objects created by end-users that runs on many platforms, and is free and open source. It includes 2D and 3D graphics, images, text, particles, presentations, web-pages, videos, sound and MIDI, etc. It includes the ability to share desktops with other Etoy users in real-time, so many forms of immersive mentoring and play can be done over the Internet. It is multilingual, runs on more than 20 platforms bit-identically, and has been successfully used in USA, Europe, South America (Brazil, Colombia, Argentina), Asia (Japan, Korea, India, Nepal), and elsewhere.

Mailing list

There is a mailinglist specifically discussing Etoys in the OLPC environment: etoys(at)laptop.org. Please subscribe to keep in touch!

For Etoys designers

To build etoys, the best thing would be to use the actual OLPC image. However, etoys authored using the squeakland.org version should be fairly compatible. Remember that the actual screen of the kids machines will be very small, even though it has a 1200x900 resolution!

We are planning a contest for the best etoys designed to work on the OLPC machines. The winners will be included in the repository distributed with 5 million machines next year. Precise criteria and the format for submissions are being worked on; but a good entry should be fun, suitable for younger kids (text shouldn't be too complex), hackable (code should be elegant), compact (disk space is precious), and should illustrate some creative aspects of using Etoys. Of course the best examples might be existing etoys rewritten to work nicely on the laptops.

Come back to this page in a few days for more information...

For Developers

The current Etoys version for OLPC is based on the squeakland.org image. It runs on the latest Squeak VM with minimal Sugar glue code.

Images can be downloaded at http://tinlizzie.org/olpc, though "Tin Lizzie" is a different project.

• etoys-dev-2.0-latest.zip contains dev image+changes (use this for developing changesets)
• etoys-2.0-latest.zip contains only the image, and preferences are set for deployment (this one is for building projects)

Remember to update your image!

• etoys-image-and-pr.zip is a zip of the very latest image and projects in the git tree

Activity Source: http://dev.laptop.org/git.do?p=projects/etoys

git clone git://dev.laptop.org/projects/etoys

There is a mirror of the latest git tree at http://etoys.laptop.org/src

RPMs: The Squeak VM and Etoys activity are packaged as RPMs. The easiest to get them is with yum:

wget http://etoys.laptop.org/olpc-etoys.repo
cp olpc-etoys.repo /etc/yum.repos.d/
yum install etoys

To stay up-to-date, just do

yum update etoys squeak-vm

Sugar: For running inside the Sugar emulator, use sugar-jhbuild:

./sugar-jhbuild buildone squeak
./sugar-jhbuild buildone etoys

Etoys are built by default in the latest sugar-jhbuild.

Bugs: Please submit tickets at http://dev.laptop.org/, select the "Etoys" component.

Running eToys on Other Operating Systems - For Testers/Developers/Teachers

If you do not have the OLPC hardware, you can still run and experiment with eToys. There are several ways to do it.

Method 1 - Use emulation

Emulation allows to "pretend" you have the OLPC laptop - essentially the OLPC laptop runs "inside" your system. You can achieve this on any common operating system you have. Please follow instructions here for description on how to do it. The above link will work if you have Windows, Linux, FreeBSD or MacOS.

Method 2 - Install RPMs (Linux Only)

If you are on any reasonably recent version of Linux, there are pre-build RPMs that you should be able to install on your system (convert to apt first if applicable). Look on the etoys page for instructions and a link to the RPM download.

Programming for the OLPC using Etoys Squeak

We are beginning a tutorial series about programming using the OLPC Squeak. Not for kids, but for programmers trying to create activities inside the Etoys environment. We have also a customized kit for the installation of a Windows version of the emulator having Fedora+Sugar+Etoys. One click only... Read how to use it at the tutorials.

Unfortunately, now only in brazilian portuguese. The link is here. The pages are in the format to be accessed, in the future, by the OLPC browser.

V-toys, a visual programming language built with E-toys

Many stuff but in French, since the language is visual, you can download projects and learn by examples. A visual language for comments will be used so that v-toys will be independant of language in the future.

I'll put some references to english examples in this page : v-toys English
