Yes it will be more concise and high-level (even if behind the scenes, the same thing happens) It will be for Pharo 4.0, an awesome release for sure :) > > Marcus

Don't worry, formatting information will be stored in Bonsai (as extrinsic information of the flyweight like node properties, not in the flyweights themselves). You won't notice that there is no original text, source will be reconstructed on demand. > > > > On 13 November 2013 12:58, Marcus Denker <marcus.denker(a)inria.fr> wrote: > > On 13 Nov 2013, at 12:02, phil(a)highoctane.be wrote: > > > Very exciting developments. > > > > How would you keep "sources" and "changes" segregated BTW?

2 cents. just want to make a note, it is important to preserve original text (yes i am talking about formatting, spacing, tabs etc).. because without it i can easily imagine you can raise compression ration to the skies.. but as to me the original text is important part of game.

Re: [Pharo-dev] Where to download Viva?

by Igor Stasenko

Nowhere. It is part of Pegasus (unfortunately undelivered GSoC project) you can extract viva classes from there , if you want. http://smalltalkhub.com/#!/~vmariano/Pegasus but i don't know what to do with it.. and if you need it (well since you asked, you are :).. we can discuss what steps to do..
