[squeak-dev] Visual Squeak

Hello,

I would like to know if there is a visual implementation of Squeak. i.e,

a drag and drop system of control blocks to write your code so that you do not have to type your code.

I find the Squeak syntax really hard to master.

Thanks,

Karen

Hi Karen,

Did you try Etoys? It does provide a visual scripting layer on top of
Squeak. Download here:

I personally had a hard time "getting" the smalltalk syntax, until I realized how much more simplistic it was than other language syntaxes. now that I understand what is going on, I like it much more than any other languages syntax.

I would recommend reading the free online book Squeak by Example.

http://squeakbyexample.org/

I found that this book explained what I needed to know about smalltalk to make me realize all of its advantages.

Actually I am looking for something more higher level than Etoys.
I would like to know if somebody has re-written Squeak as a complete visual
(drag & drop) system so that we do not have to worry about making syntax
mistakes when building programs.

Some 10 or 15 years ago, a student of mine (Dr. R. Giffen) did
something like that for VW. Very beautiful. There is an MSc thesis
that he wrote about this and I might also be able to find his code.

Re: [squeak-dev] Visual Squeak

Here is a link to i think what Ivan is talking about, but you have to
pay, and it is not the code, only a paper.
http://ieeexplore.ieee.org/Xplore/login.jsp?url=/iel4/5257/14250/00654734.pdf
?arnumber=654734

I could not find the code, but I didn't look very hard.

Try scratch.

Re: [squeak-dev] Visual Squeak

You can also try Maui: http://wiki.squeak.org/squeak/3836.

I'm not sure if it is "high level" enough for you, but it works in Squeak 3.9.

Etoys is higher-level than Smalltalk, so maybe you do need to better
explain what you want. Etoys *is* a drag&drop system.

I saw you worked with Alice - Etoys tiles are similar to Alice tiles.
What kind of application do you have in mind? What audience should use
it?

Re: [squeak-dev] Visual Squeak

Randy's code did what Karen is talking about - you could switch
between VisualWorks (VW) text and (Randy's) graphics mode browsers,
move syntactic units around, etc., preventing syntax mistakes and so
on. It was demoed at obne of the OOPSLA conferences.

I can't remember the details now but I will try to find the paper and
the code and make it available here. But it has been a long time ...

Well you can switch Squeak's system browser to tile mode, too. This is
called "universal tiles". But I am not sure yet what Karen is looking
for. I wouldn't recommend using it anyway.
