Try DBJr (HyperCard-like stacks in Lively Kernel)

DynaBook Junior (DBJr) is an end-user authoring system in the
tradition of HyperCard, SuperCard, and Visual Basic. If you remember
HyperCard, you will recognize the concept of a page, a background,
and a stack. Load this page in Chrome:

http://lively-kernel.org/repository/webwerkstatt/users/TedKaehler/DBJr%20stack.xhtml

DBJr lets you store information freeform without the restrictions of
a database. You customize the action of a button by writing a
script. It is even possible to make games and other
mini-applications.

The world has a demo stack that explains DBJr. You can make a new stack with
$world.get("Stack").demo()

From that stack, you can use the user interface to add and delete
pages, drop in morphs of any kind, and move morphs to the background.

I built DBJr originally in Squeak, and ported it to Lively Kernel.
Many thanks to the Liver Kernel team.

LK DB Jr looks interesting and I have all sorts of questions. Is there a more appropriate forum to discuss it specifically?

Re: Try DBJr (HyperCard-like stacks in Lively Kernel)

Why not use the page/world and discuss it ;-)?
In case you do not have an account, sign up at http://www.lively-kernel.org/trac and then you should be able to add discussion TextMorphs to the world (and save it).

Best,

Are you suggesting this would be off-topic on this list? I for one would like to see the discussion happening right here.

Given that the context here is DBJr in Lively Kernel, this is the right place I think. But if what you're looking for is to understand where it all comes from, you can find lots of good stuff hiding here:

http://vpri.org/html/writings.php

Everything on this page is worth reading. There's a lot of context and rationale supplied in the yearly status reports, but if you're feeling adventurous, check out this one straight away:

http://www.vpri.org/pdf/m2011001_dbjr_spec.pdf

The above link is to a high level specification of what DynaBook Jr. is.

It's worth noting that the previous (Squeak) implementation has been discussed elsewhere; I can't recall if it was on the FONC list or on squeak-dev. I usually google on "Ted Moshi image" to find that.

But yeah, this is about LK so let's hang out here:)

HyperCard, for every computer. Holy cow!

Oh the times they are a-changin'...

Re: Try DBJr (HyperCard-like stacks in Lively Kernel)

Hi everyone -

I once built a HyperCard implementation in LivelyKernel myself, which
can be found here:
http://lively-kernel.org/repository/webwerkstatt/projects/BP2012/IPadPresentationPages/Hypercard.xhtml
.
Initially this was supposed to be a demo implementation to see how
good LivelyKernel works on iPad - or more how well our progress on
bringing LivelyKernel to the iPad is going (I'm part of a bachelors
project which implements collaborative and mobile features). However,
thinking about the functionality of the background, it kind of ended
up in implementing morph diffing and merging for the PartsBin, which
is still WIP...

Re: Try DBJr (HyperCard-like stacks in Lively Kernel)

Hi Astrid

This is nice! We should join forces -- we actually need a "DBjr" kind of media that can make "universal pages" i.e. anything desktop publishing can do, but also programmable ...

Cheers,

Alan
