Even though the last thing the world needs is anyone following my code style,
my plan is to give my script a quick once over and post as in at the jwiki.

This looks promising.
I currently have two quibbles which you might want to reject:
First, the additional markup seems to get in the way for some typical

dimensions. I understand the idea of consistent display of information, bu

Just an update on the visualization of J results.
I have done a second video/blog post on using CSS and HTML to display results
on JHS. It provides examples of a system that allows you to distinguish between
1 $ 1 , 1 1 $1 , and 1 as well as displaying arrays with zeros in the shape
such as 0

Sometimes the zeros can affect the result ev
Zeros in the shape are a bit strange, yes. If the only zero is in the
last element of the shape you will a blank line (or blank lines) based
on the rest of the shape, but you have no idea of rank. If you have
any zeros anywhere else in the shape you will get an entirely empty

Raul,
One of the challenges I have found is in shapes with more than one zero value,
because that second layer of nothingness is difficult to distinguish. I think
by enclosing the shapes appropriately, this can be done, but not by text alone.
It reminds me of the last verse of "The Snow Man" by

More specifically, leading 1 dimensions are invisible (and so is "type
information"), by default.

Thanks Pascal,
I think that 1 6 $ i.6 and 6 $ i. 6 are probably the most commonly confused,
but the displays of 1 1 6 $ i.6 and 1 1 1 6 $ i.6 also look the
most useful feature would be

You are reminding me of a variety of issues.
I remember, when I was first learning APL, that I was frustrated with
how inefficient APL was at doing what I might call streaming IO, or
what I might call wart-for-wart emulation of ad-hoc code.
I also remember how kx.com's languages deal with this is
As a bit of a response to the whole question of what we see and what we get, I

I think the blog post and demo video gives the flavour of the journey.

Makes perfect sense now. The atom vs list distinction wasn't clicking
earlier. I had become so used to working with arrays that everything
became an array and I had completely forgotten about scalars. The
dictionary entry on nouns also covers it well,

I'd say forget the binary representation.
The primitives, namely ;: u;.n u\ u\. u/. produce lists even when there
is only one item in the partition. Very regular.
The anomalous case stems from simple old keyboard entry. You ran into
trouble from
'a';'bcd'
because 'a' creates an atom, wh

I had a feeling that the arrays were structurally different but I
couldn't figure out how to tell.
I also narrowed it down to my use of cut. I will study that to
understand further
These were the ways I tried to look before

The following may be helpful: Arrays that "look" the same may not be the
same. For example, the following arrays all "look" the same but all differ
from each other:
123
,123
'123'
1 1$123
1 1 1 1$123
1 3$'123'
1 1 1 3$'123'

Strings match only if they have the same shape and the same values.

but look:

It's a totally different question. You are asking if the atoms match.
The answer is a list rather than a single boolean yes/no:
$ (,'=') = '='

That worked. Thank you very much for the reply. I am relieved.
