How to pimp a clean etoys image to a luxurious Epaati image

For this procedure it's helpful to have the etoys-migration-files directory handy. This directory is for the moment only situated on one of the OLE Nepal internal servers (Om's server). We've got a very slow connection to the outside world, so putting it on an external server isn't very practical at the moment. If you, as an external developer, want to work with etoys, you can pull from the soon to be initialized Subversion repository. If it's not there yet, mail us, and we'll find a way.

What follows is a step by step instruction:

Get the latest Etoys image

That would be: EtoysV3.sources and etoys-dev-3.0.zip

Place EtoysV3.sources in the directory where you've got SqueakV3.sources, and unzip the etoys-dev-3.0.zip to a directory of your preference.

Or just use the stock Etoys image for now. It doesn't really matter.

Install Monticello

This is not a straight line procedure, since the standard Etoys image has diverged a bit from the main squeak line. For now see the 'Installing Monticello on your Etoys image' section in Etoys Tips and Tricks.

Install the latest OLE Monticello package

Open a Monticello browser and click +Package. Enter 'OLE' and accept. Then with the (empty) OLE package being highlighted, click +Repository and select 'http'. Change the location into 'http://squeaksource.com/OLE' and leave user and password be. Both should say 'squeak'. Accept. Highlight the repository and click Open. Wait for a bit and a new window should open. Select the latest OLE version from the pane on the right and click 'load'.

And now you should have a new and fresh OLE lib installed.


Local patches

Go to the changesets directory in the etoys-migration-files directory, and file them in.


Devanagari fonts

Go to the devanagari-fonts directory in the etoys-migration-files directory. Drag the Devnew.ttf file into your etoys image. Drag a textmorph from your supply-bin, conjure up it's halo, select DevanagariNew and select a point size.

Then again conjure up the halo, select the DevanagariNew font and select 'new size'. Fill in 60, 72, 100, 200, 300 or 400, and repeat the process to add the rest. If you are thrown into the debugger, that's to be expected. We should file a bug report for that if it's not already done.

Then execute:

TTCFont registerAll

As from [1]. We should still submit a proper patch for this.


And we're done.

Note that in general Devanagari can't be rendered properly at the moment. The stuff we did in the preceding section is only meant for rendering of Devanagari letters. The latest news is that someone from the olpc-etoys dev list was working on it. Need to investigate.

Also there's some way to render text properly by importing text from some application programmatically. Look through the olpc etoys mailing list, topic 'Squeak VM status concerning language encodings' for further details.

yes and no sounds

Just drag the right01.wav and wrong03.wav files from the common-sounds folder under etoys-migration-files into the etoys folder.

We play all sounds as wavs at the moment. Preferably they would be something like ogg files to save mem.
