[Jbeta] j 1.2 (1.22) is now available
Hey Eric, The jal/jw'' combo absolutely rocks!! It did take about 40 seconds to download the files while on my iPhone 3GS and the return button was highlighted during this time and the phone non responsive. It may be worth noting this delay in the instructions or even better use some sort of a progress bar. Seriously though, as someone who is still on the J learning curve, the ability to have the reference materials in the hview is huge. I think that you could create exponential growth in users if your final app loaded and opened one of the J reference texts and the reader could test as they read in the hview window. A procedural programmer reading and playing along with J for C programmers would not remain a loop coder for long! Off to play. I really hope that Apple gives you a quick thumbs up on this one. The world needs this app (and they don't even know it yet). Cheers, bob -- For information about J forums see http://www.jsoftware.com/forums.htm

Re: [Jbeta] 1.19
Hi Eric, Of all the buttons, the one I think that you may be able to do without is the keyboard button. The keyboard already appears when you tap the text entry field, and it disappears when you click on the screen away from the keyboard. It is nice to have an overt way to bring the keyboard in or out, but I don't see that it makes up for the shorter space in the text entry field. It is certainly possible that I am missing some added functionality that the keyboard button provides and would love to hear if that is the case. On a second note since we seem to be wrapping up the beta, have you given any bought to including the J documentation through html as part of the download. That html window seems to me to be a natural way to provide help and not get in the way of the J text area. This is becoming even more apparent with your last 5 screen option, which means that even with graphics or plots you could use an html help and then swipe back to the graphics display. The documentation already exists on the Jsoftware site in html format so accessing via the web is a quick fix for it, but it seems to me that having documentation available even when you are off the grid is a feature (especially given the quality of the J learning materials). Just my 2 bits, you've done a great job on this beta. cheers, bob On 2012-05-30, at 7:12 AM, Eric Iverson wrote: Re the bullet button - read the simple docs.

Re: [Jbeta] update
Since SVG is compatible with html5, you can write out SVG code and have it display in the hview. It works well for creating interfaces and mapping applications ( and it is working with hview including previous 5 displays). Would it also be possible to load the documentation through the JAL? I have done this easily through the server version of JHS 701 on my laptop, but I am not entirely sure how it would work in the world of iOS. I also noticed that if I four finger swipe to another app, then change the orientation on the iPad, when I swipe back to the J application it begins with the splash screen for a second or two before it updates back to the current state of the working session. Doesn't seem to be a problem with the iPhone as it seems that the animation in app switching may correct the problem.

Joey, Thanks for the tip on the hold on !/, for the quote . Additionally, if you are on the number or special character keyboard on the iPad or iPhone, holding the ' key will also give you access to the ` (backquote) character, which comes in handy when using @. as the backquote does not show up on any of the onscreen keyboards as its own key.

Re: [Jbeta] Editing files introduced through iTunes
Thanks for the response, I had not thought of that.

I can get files to the root level, I just don't seem to be able to edit them from that position. I will see if evernote allows me to change the contents of the J folder (but I doubt a third party app would have this access).

Re: [Jbeta] Editing files introduced through iTunes
Hi Brian,
I tried a variety of ways to address the files and when none worked I looked at
the je definition.
je_z_=: 3 : 0
assert. 0~:#y
if. -.+./y e.'/.' do. y=. '~/user/',y,'.ijs' end.
if. -.fexist y do. ('NB. new file created',LF) fwrite y end.
smoutput'ioscmded ',y,LF,LF,~jpath y
i.0 0
)
I did try rewriting this to allow for the root files position but I couldn't
come up with the proper way to reference.
Late breaking news: As I was working through my reply I took another look at
that fourth line and by substituting '/file.ijs' for y … it worked!
I think before I had missed that the .ijs extension was required when the rest
of the verb is removed.
Thanks so much for your help

Re: [Jbeta] Editing files introduced through iTunes
Hi Eric, Now that I have the '/filename.xxx' format worked out for addressing root files, I have found that the fread fwrite approach is the best.

Also, I would imagine that when the JAL is implemented that it would be the preferred way to build the local documentation of dictionary etc. . In the meantime the obvious idea is to copy over the files into the j app root and then fread fwrite them into the appropriate file structure. If this is the case, I will be waiting for the JAL :) , but I am just mentioning this in case you know of an easier way.

Re: [Jbeta] Editing files introduced through iTunes
Here's to playing in the sandbox :) As I thought more about it and your answer, I see the reason behind Apple is providing security by restricting the access that apps have to other information, so that even if we did manipulate the app there would be severe restrictions to what the app could do to the rest of the device. Still, I love the flexibility that the choices that you are making provides. I am exploring SVG right now and, as far as it is compatible with html, the html window, j window combination becomes a very powerful way to manipulate graphics. I also include a link to Bret Victor's Inventing on Principle .

Re: [Jbeta] Portrait vs. landscape
Hi Eric, Rotating the pad back brings back the controls, if that is what you mean by fixing things. I noticed one further thing about the aspect ratio changes. If you begin with portrait mode and the HTML window and onscreen keyboard are both visible, a rotation to landscape will cause the HTML window to disappear. If you start in portrait without the onscreen keyboard (tap anywhere in either the j or the HTML window to lose the onscreen keyboard), then the HTML window remains when you go to landscape. Hope this helps. Cheers, bob On 2012-05-12, at 11:37 AM, Eric Iverson eric.b.iver...@gmail.com wrote: Thanks for the detailed report. I can reproduce this and it should be easy to track down and fix.

Re: [Jbeta] Invoking the JGTK editor from the terminal.
Hi John, A possible near miss for JHS NB. In Unix based systems this works. x specifies the opening application and y the document NB. eg. 'TextWrangler' CallEdit '/Users/jay/test1.html' makes the TextWrangler application open the test1.html document CallEdit=: 4 : 0 2!:1 [ 'open -a ',x,' ',y ) I haven't found a way to create a tab, although this may be child's play to someone who actually knows what they are doing :) cheers, bob On 2011-01-30, at 8:47 AM, John Baker wrote: open works like a charm in gtk - thanks everyone.

Re: [Jbeta] Gtk on Mac
Hi John, The JHS was pretty easy to get going for me. Just click on the red J in the J701 folder. This should activate a terminal window, executing some commands and culminating in an URL that you can cut and paste into the address box of the browser of your choice. The J session will run as a window/tab on the browser. Hope this helps.

Re: [Jbeta] Jsoftware JHS available
Thanks Eric, I actually did kill my server and restart last night and have not seen the login/logoff problem occur again (see update below). I'm still using the same configuration, so we may be able to rule Chrome or OSX 10.6.4 as the cause (although you never know with intermittent problems). I was not using the back button on the browser tab, but just reentering the password, so I don't think refresh is the cause of the escalating attempts. Once killed and restarted the password worked, so the caps locked or bad password issues were apparently not the cause (whew!). Late update, after successfully logging on and off several times over the last 15 hours, I just got the '10 attempts - maximum 5' message and can't log on. I had not seen any unsuccessful logins since the most recent restart. Would you like me to kill my server and restart now, or is there a benefit to letting you have a look again? I think I may give it a try with Safari on the next restart and see if it is a browser related. Your thoughts?

Re: [Jbeta] Jsoftware JHS available
Thanks Eric, Yep, it was a complete surprise, there were no indications of any bad passwords previously and then ...10. One more attempt just now gave the count at 11 so if someone is accidentally trying to get in (I try to think of the better side of people), they have not tried recently. I'll restart and run in Safari for a bit before I go back to Chrome to see if that is part of the issue.

Re: [Jbeta] JHS login failures
Thank you for changing the Subject line to something more informative Martin. I am also relieved that I am not the only person experiencing this password challenge. Reading your description, it sounds as if we should see at most one failed attempt (unless we make a mistake in the password). I have always been able to sign in when my attempt level is less than 5. This indicates that given the opportunity, I am trending toward submitting the password correctly. :) I'm glad you are observing through the Opera glasses :) We may see different results with different browsers.

I think(!) I can see the same effect with Opera. My impression is that the browser's Password Wizzard may be auto-submitting the form once before letting the user having a second try. I may even collect a failed login upon logging *out*, because that returns to the login page. Let's see how soon I reach the threshold. To track this down, it would be helpful if the server would echo back the password it received but didn't accept. (Just until this issue is resolved.)
