Hi Chris
I need urgently to unsubscribe to J chat. Currently I am unable to
participate and my mailbox is becoming overloaded with J chat messages.
I cannot see an "unsubscribe" button anyway. Can you please point me in
the right direction?
Thanks
Tony

The old form editor was needed because in the old days, there was no layout
manager in the UI so controls had to be given an exact position on a form.
Fine-tuning this manually would have been tedious. However, there were
still problems, for example the layout that worked fine on one resolution
or OS may not have worked on another. I remember spending a great deal of
time on manually fixing up form editor output so forms worked properly
everywhere.
However, Qt has a nice layout manager. Control positioning is easy and just
works in all platforms.

I can understand the appeal of the WYSIWYG aspect of the old form editor,
but I much prefer the current system for designing and building forms. I
spend much less time aligning controls perfectly and the form resizing
behaviour is much better.
As for the cross-platform experience, there is no contest - the current WD
implementation is far superior in terms of functionality, reliability and
appearance.
I'm sure that the state of flux of GUI development from J6.02 to J8 didn't
help foster a plethora of GUI apps, but I think the paucity of GUI apps is
primarily due to the focus of the majority of users than the facilities of
the language.
The GUI's I've developed are far from complex, but I've found them
relatively easy and satisfying to build, and compare favourably with those
of most other languages for GUI-based tasks on Rosetta code.

J used to be great at making guis and had the best form editor on the
market.

I would love to have easier ways to create guis.

So it seems that J is not a self-contained language for making GUIs: you
also need to know either html and js or qt. Clojure has the significant
advantage that the GUI code is in idiomatic Clojure.
All I said was that J isn't a _good_ language for creating GUIs when
compared with Clojure, Python, or Java for example. I would have thought
that would be uncontroversial: in fact there are very few examples of
GUIs
in the repo, and none are elaborate. Evidently no one in the J community
places a very high value on GUIs.
Which is fine, not every language needs to be great at facilitating the
construction of GUIs, there's a place for scripting languages. I'm happy
to grant J the distinction of being a superb calculation and scripting
language, but for GUIs it happens to be mediocre.

JHS is using HTML as a front end.
There are numerous ways of interacting with HTML tools.
You can see examples and demos doing gui/graphics etc and mixing with
javascripts.
It may be difficult to distinguish between what is J/Javascript.

After reading "Algebra as Language" and "Computers and Mathematical
Notation", I'm starting to see J the perfect language for numerical
computation. But for general purpose programming I can see Dijkstra's
point.
When APL was designed computers were seen largely as calculating
machines. But by the 1970s GUIs were starting to be developed, and
computers were being applied in areas where tensors were no longer
adequate
as the sole data structure. One thing general purpose programming
languages must have is extensibility, and that J lacks.
I'm trying to work out what the appropriate use cases are for J, and I
think it's calculating with tensors. If you need more than tensors, or
if
you need more than calculation (e.g. GUIs), J is not a good choice.
