I have been trying to learn Etoys, Squeak, and Smalltalk, and finding
it heavy going. After considerable exploration, I have found Squeak by
Example, Programming in GNU Smalltalk, OLPCEtoys, and the Etoys
Reference Manual (FLOSS Manuals). So now I have seen, but not fully
understood, how to create objects and methods; various development
tools, viewers, inspectors, and so on; and some of the structure of
various Smalltalk-based systems, particularly Morphic.
With what I know now, plus my knowledge of other programming
languages, I can see a path to understanding most of command-line
Smalltalk and graphical Squeak development. But so far, I do not see
how to do Etoys development. Bert Freudenberg clarified several
questions for me yesterday: Many Etoys projects were built in Squeak,
not in Etoys at all. Fine. So then what makes a Squeak construct
suitable to be made into an Etoys project, and how do you put it into
the library? Smalltalk was meant to be taught by experienced
teachers, not discovered by students. Fine. But how do the teachers
learn it?
I found out about the keyboard shortcuts in Etoys by reading the
incomplete draft Etoys Reference Manual at
http://en.flossmanuals.net/etoys-reference-manual/They are in the User Interface Chapter. So now I know how to open a
System Browser and a Workspace from Etoys, and how to get at
everything that is on various menus. Unfortunately, this draft manual
does not give the shortcuts for Linux, just for Mac and Windows. Also,
there appear to be serious errors and omissions in the tables and
lists. I have not found out how to open a World Menu. Also, every time
I try to open an Event Theater in Etoys on Ubuntu, Etoys crashes.
(Etoys for Sugar on Ubuntu won't even open properly. I'll have to try
Fedora in VirtualBox.)
I will have many more questions in coming days.
