I claim that this newsgroup is biased !! Sure enough, personally
I rather take it as my own fault that I have *not* been using objects in
IDL yet -- there are just always so many things that have to be finished
on time that I never get around learning about them (in fact, I haven't
even fully digested all the information that David gives on widget
programming in his book yet ... sigh ... if I only had time to improve
my EXPLORE program ... end sigh). But: e.g. in our research group there
about 10 people using IDL, and 1.5 of them participate in or even read
this newsgroup. Most others (and I would say that's probably typical for
scientists) have some basic knowledge in programming (sure, FORTRAN
(=f77) mostly), but not much beyond that. They are quite happy if they
can use e.g. a readdata.pro to retrieve some ASCII data from a file, and
they rejoice when they learn about the where function. Most programs
written in our groups start out as 5-20 lines of code, hand-tailored for
one specific plot. And most programs stay that way, too. I am already
happy if my colleagues make use of some of the library routines that
I have written or gathered from various sources, but if I were ever to
tell them: "Here's this perfectly handy and powerful routine, and it's
even object-oriented!" they would just thank me very politely but never
speak to me again ;-) There once was a german chancellor who said
"Entscheidend ist, was hinten rauskommt" (free translation: "it's the
plot, stupid! [not the program]"), and he sure was right on this one.
But if David ever writes another book on object oriented IDL programming
techniques, I may well become one of his customers!
Best regards,
Martin
