[comp.object] Libraries for OOLs

gabriele@foresthill.toronto.edu (Mark Gabriele ) (10/31/89)

The following is a portion of a project proposal for a master's 
course in language design.  I am posting it here because I've been
having difficulty locating good sources of discussion of libraries
for object-oriented languages, and I would greatly appreciate any
pointers that readers of this newsgroup can think of.

Object-oriented languages are intended to make the software
implementor more efficient by stressing reusability of software.
This, in turn, is accomplished in part by providing libraries of
software which can be invoked whenever needed.  Perhaps the most
important aspect of an object oriented language which touts
reusability as its outstanding feature is the ease with which its
library classes can be applied to the everyday programming needs of
the people who use the language.

If the library of an object-oriented language is so important, then
what goes into the library?  How does the designer of the language
decide what should be there and what should be excluded?  Is there
some algorithm which can assist the designer of an object-oriented
language in determining what library classes should be distributed
with the language?

The project which I have undertaken is to study the makeup of several
object-oriented languages' libraries (Smalltalk, Eiffel, C++, others
if the information is available) and ascertain what elements they have
in common, and what they lack.  It may be reasonable to assume that
some commonality exists among their libraries. If this is true, then
it may be possible to develop a rudimentary algorithmic test for
inclusion in an object-oriented language library which may be applied
to candidate library classes.  The result of this project will be a
paper detailing my findings about the makeup of libraries for
object-oriented languages.

Responses to either myself or the net are welcomed.  If I get several,
I will be happy to summarize and post here.  My thanks in advance.
