Your "Items" movie aptly meets a training need. It also fills a blind-spot
in NuVoc – as it's presently conceived. More so than your Head ({.) movie
and its proposed series. That is, considered as a proof of concept, rather
than a work of art, where it can't be faulted.
I didn't think there was a lot of future in the idea of a Head-type movie
for each of the 121 primitives documented by NuVoc. The idea's come up
before, and I haven't changed my mind about it. It's a helluva lot of work,
fated to be mostly wasted.
Here's why.
Originally NuVoc aimed to deliver online help at the point-of-use in the
shortest possible time, with minimum demands on the beginner's overloaded
brain. It avoided diverting the user's attention from the coding task in
hand, i.e. their own, whatever it was. It assumed he or she had no time
(…just then) to settle down to a sublime exposition of J theology. That's
why there's a line across the page (originally a heavy line!) with "More
Information" below the line.
I fear your Head ({.) movie and its kin would go below the line, in amongst
"More Information". This would condemn it and its siblings to being watched
perhaps twice or 3 times in the whole career of any given novice user, and
then for perhaps just 2 or 3 primitives. Your "Items" movie escapes my
criticism by being both more general and much better targeted.
Let me suggest what these "2 or 3 primitives" are: Rank ("), Cut (;.),
Atop (@) &co.
They're all conjunctions. Precisely where NuVoc meets its greatest
challenge (…and fails, some would say). NuVoc does best when it deals
separately with verbs and adverbs derived from conjunctions. IMO here's
where your videos would really show-off their power.
Example:
Buried in the "More Information" section of Atop (@)
https://code.jsoftware.com/wiki/Vocabulary/at …you see a marvellous diagram
(due to Henry) of what verb composition is all about. I used to study this
thing like a mandala. But might it be better as a movie? Or supported by a
movie?
