Jim,
I appreciate your reply, and better understand some of your motivation.
I see some value in applying your ideas to create "wizards" that will
help practitioners of other computer languages to learn J. For
example, taking the most common idioms from other languages and
providing a semi-automatic translator, it may be possible to help
transition curious programmers of other languages into the World of J?
As you did with Smalltalk, perhaps a good excuse for better learning J
might be to write a J program for converting idioms from popular
languages (eg: ruby, python, C) might be useful?
eg: (Ruby idioms -> J)
where v is a vector, s, s1, s2 are strings, n, n1, n2 and l are
numbers, and e is an arbitrary type element.
Ruby J
v.map{|e| f(e)} --> f v
s1+s2 --> s1,s2
s1<<s2 --> s1=.s1,s2
s[n] --> n{s
s[n1..n2] --> (n1+i.>:n2-n1){s
s[n, l] --> (n+i.l){s
etc.
This might help convert entire methods into functionally equivalent J
code.
Of course, J is sufficiently different that this won't work for large
bodies of code -- only small, relatively simple algorithms. But, it
might be interesting to see what such a translator spits out for
increasingly larger code fragments.
Kind of a bottom-up translator.
