Pascal,
Paint is not a js function, paint is the j verb. Does that clarify my problem?

appologies if I misunderstand,
If your js paint event took the full list of commands, then you wouldn't have
these problems, IMO, and would solve the issue of general repaints being
sometimes required for other reasons.
If I understand your design, if the jhrajax received a list, updated the js
Joe,
As it is, J processes all the paints, but the client JS only gets the
**first** paint -- the only paint JS expects --because that first paint
contains the jhrajax, like all paints do. J produces a paint for every
simulated move, but does not know how to batch them together.
I am assuming tha

Yes. I sort of follow your example. Btw, I perhaps used the word stack when
I should have said queue, because I believe a queue is first-in-first-out,
which is what I want.
So, I imagine the command event at the jhs side sending a command and the
jhs responding by emptying the queue

Console.html in now attached, but named console.txt. The jwiki told me it
was attached, but when I left and came back, it was not attached,
presumably because of jwiki disallowing an html file attachment, as someone
said.
Apologies, again.

This is the only option I can think of too. Let me restate the
problem in more general terms:
Hmm...

because you would need to rename it to use a different extension
- perhaps .txt instead
I have found the problem, but cannot fix it in console.ijs because my mind
is frozen.
It can be fixed manually by entering the following in the jijx window. At
one time I new how to add this to the console.ijs, but not now.
load'~Projects/tgsjhs/tgsjhs.ijs'
I apologize. I have been using console
$ ls j64-801-user/projects/tgsjhs/
console.ijs tgsjhs.ijs tgsjhsutil.ijs
Here's what I did to reproduce this problem:
(1) stop and restart jhs (so I have a clean session).
(2) reload my ijx window
(3) in my now clean ijx window, enter the command:
load'~Projects/tgsjhs/console.ijs'

Raul,
I think you are referring to the ijx window collecting the log of inputs.
Yes, that is definitely worth looking into. I can almost see a light at the
end of the tunnel. I need to think more about how the multiple results
would be collected by js. I think there is an example in the demos for
Pascal,
I am thinking the user would just supply 1 command, but it could be a
command that contains multiple commands, like the repeats conjunction
produces. Below I have copied the example I suggested in my first post
today. I may have forgotten to give the example of its use: (3 repeats
fd)10 .

you could have a ; separator for commands?
';' cut 'fd 20 ;rt 55'
+--+-+
|fd 20 |rt 55|
+--+-+
';' cut 'fd 20 '
+--+
|fd 20 |
+--+

Raul,
I just diff'ed the wjiki files with the one I am using and do not get such
an error.
Did you download both tgsjhs.ijs and tgsjhsutil.ijs? They are both required
and must be in the same projects directory. I suspect you did not download
the tgsjhsutil.ijs file.
I am using both Safari and Chr
I understand your dilemma, but I've got some other things I'm working on,
so I can't put too much time into this.
Do you have charles proxy installed, so you can inspect the ajax requests
in flight?
Note also that the way the ijx window works is it builds up a complete
history which can be sent i
Raul,
Those were great instructions. I have been to the console before, but only
saw output, for example. I did not know you could enter commands there. And
entering console.log(gl) I got lots of output including expandable lines
with arrows/triangles pointing to the right.
That queueing business
I have your code up and running, and am able to change the background
color.
I get an error, though, when I select the text field containing 'fd 20' and
hit enter. That error looks like this in the ijx window:
*** event handler error
ev_command_enter 0
|value error: State
| y=.0 Eye}yxs&Sta
I think I see the problem.
If you really want multiple calls to jhs then what you need to do with
entered commands is have them add themselves to a queue and then have each
of them send the first entry in the queue to jhs (and have the handler then
send the next entry on to jhs). But that strikes
Raul,
I am not sure console.log's would help me here, but I am willing to insert
them if I can learn now. Perhaps my reply to Pascal can explain better my
conundrum. The problem is not that jhs and webgl are surprising me; my
problem is that I have no idea how to accomplish the multiple command
fe
J sees 'fd 10` for 1 command, or it can see `(5 repeats fd) 10` for
"multiple" commands. If there were not the problem of communicating between
jhs and js, that is if only j were involved, then the paint verb would be
called 5 separate times by something like opengl. But now the first `fd 10`

I'm not sure if I can get to this today, but what you are doing here is
closely related to my own interests, so I really would like to help you
solve it.
>From your description, I suspect the problem is in step 5. Without looking
at your code, though, I can only speculate about what's gone wrong.
in step 2, can you tell us what J sees as the y argument for 1 command and 2+
commands?
it sounds like the output of that function the full sequence of moves? (using
cached previous moves)?

First the good news. Joe's idea to use alldata.push(row); to '...push the
single row to a javascript array...' works fine, except that only after
much head scratching I discovered I needed .concat in addition to .push for
turtle paths, (not for turtle avatars).
The bad news is pretty devastating.
