Re: [Jgeneral] J Playground - Major upgrade announcement and approaching version 1.0
Someone has changed the behavior on Android. I say changed because there are far too many states for me to be certain I can enumerate them all. 1) Both Chrome and Firefox now work, or don't, in the same timeframe 2) Almost always, when I first try to use it, there is no response to input from Term or Edit 3) I first discovered it could work after using it successfully from Windows Chrome, and then switching to my Android tablet, surprise me so much I changed from Foxfire to Chrome and learned it worked there as well 4) Recently, I've noticed I can usually revive it by trying one or two Labs on my Android tablet 5) Sometimes, it appears I'm getting output from some other session, as it doesn't match what I typed or have in Edit. This one is rare, I haven't discovered how to recreate it. Also, while I expected plots not to be copyable, comments which appear green in Term, are not there when I paste into a text editor after copying all of Term. -- For information about J forums see http://www.jsoftware.com/forums.htm
Re: [Jgeneral] J Playground - Major upgrade announcement and approaching version 1.0
Thanks Paul and others.. My limited time lately has been working on getting deep into the J code and compilation to WASM to resolve the failing unit tests - https://github.com/jsoftware/j-playground/issues It's a much harder climb for me so progress has been slow. I think I've narrowed some of the issues down to SLEEF (which I didn't even realize was being used in J since 2020 -- neat) and sse2 instructions on WASM -- https://sleef.org/ -- there's also something possibly with the stack size or stack alignment, which is a bit outside my area of expertise. It's been a bit of a slog. The good news is that most tests are passing -- so the playground is working well on the whole with J. The bad news is that some of the failing tests may be contributing to glitches like the 3d surface plot not rendering correctly... I'd feel better knowing that there aren't any corner cases where people get wrong answers on the playground. I'll post more to the mailing list once there's notable progress.

Re: [Jgeneral] J Playground - Major upgrade announcement and approaching version 1.0
Really impressive work! I agree with what most people said before. For me, the 3d surface plot doesn't work and neither does viewmat (both on android/firefox and on windows 10, chrome). I don't know whether it's still work in progress, but it might put off people if some of the examples don't work. I'd be happy to help debugging it, if needed.

…oh and I think the inline plot-output is most impressive. But, since people who generate charts have an immediate use for those charts, consider optionally replacing the chart with a link to where the chart may be found, the session history browsed and the PNG, PDF, whatever, downloaded.

Re: [Jgeneral] J Playground - Major upgrade announcement and approaching version 1.0
It has a nice feel about it. JQt users will like the resemblance to JQt, right down to the default color of the window backgrounds. A user-cue for what's-what. Minor bug: entering a blank line does the message: |syntax error | output_jrx_=: |[-1] I think that should be a no-op, as in JQt. Consider also using it as an alternative for advancing a lab (when a lab is active). I'm delighted to see good lab support for a J IDE aimed at the first-five-minutes of J contact. Labs sugar the J pill. Also, if you're a J novice from a numerate discipline like statistics or engineering (surely the main J audience), there's nothing like seeing something you already recognize being handled in J.

Re: [Jgeneral] J Playground - Major upgrade announcement and approaching version 1.0
My indenting suggestion was about, how the input line for an interactive command has a default indent in jqt (I think console as well), so that it is easy to distinguish the screen history between commands and results.

Re: [Jgeneral] J Playground - Major upgrade announcement and approaching version 1.0
Is this what you meant? load 'stats' load 'stats' i. 3 0 1 2 Running the latest J Playground on an up-to-date Chrome on Linux. I really like the Playground, and I agree with all the comments here that I've tried out myself (I haven't tested them all). If it's reasonably doable, it would be nice to have it work with Android and Chrome. From what I read, that's a bigger segment than either IOS or Android and FF. Because I don't even find the J Dvorak keyboard easy to type on (compared to a real keyboard), I tend to use J on my phone more as a calculator. Were the Playground functional with Android and Chrome, I might use it instead of J/Android. Are there limits to how many people might safely choose such an approach? Thanks!

I also don't know what Center Panes under View does. 1. The Server menu with Connect and Disconnect is from the 2018 original, which connected to a remote server. Not needed in this version. 2. Line and Show means run the line and show the result, e.g. A=: i.3 would display 0 1 2, rather have no output. This is the same as Jqt, and should be useful in a demo. 3. Center Panes does just that, i.e. you can resize the Term and Edit panes as you like, and Center Panes will center them back. We should have the Help|Playground menu open a wiki page with better documentation.

Re: [Jgeneral] J Playground - Major upgrade announcement and approaching version 1.0
My initial response was to the appearance of this is approach. Issues I've discovered in subsequent use in no way have distracted from that initial opinion. I found several things to report, but I'm getting different behavior on Android where I have to use Firefox and Chromebook where Chrome does not crash. My children have the Chromebook and Windows 10 machines so I have to wait till they're not working to try experiments on either of those. The first issue isn't really in this app. All of the labs I remember using begin with the sentence: To advance the lab, select menu Help|Studio|Advance or the corresponding shortcut. To my knowledge, the Android version has never had that menu choice, but it's always been so different than every other platform I've never reported it. That seems important to overcome on something you'd like to show people first. If I'm right about that sentence being in every lab, perhaps the simplest thing to do would be just replace it with an empty string in this app and assume people would use the advice at the top of the Labs menu. I haven't tested Windows yet, but so far I cannot advance a lab with Crtl+> anywhere. Pressing enter after a result echos the last output, unless there was none as happens with plot. In that case Edit Run > Line echos the line you typed as part of your entering the request initially, and Echo Run > Line & Show has output_jrx_ under the plot. As it is currently working, I don't know the point of having Line & Show under Echo Run. I don't know what Connect and Disconnect under Server do. I also don't know what Center Panes under View does. My own preference for introductory interfaces is to provide as few choices as necessary, and to choose both descriptive words and organizational positioning to ensure the meaning of each is clear. To that end, several of the items in the previous paragraph might best be removed. Furthermore, a number of the options under Links seem better categorized as Help, and I would argue for choosing one initial form of help even though I don't much care which one it is. -- For information about J forums see http://www.jsoftware.com/forums.htm
Re: [Jgeneral] J Playground - Major upgrade announcement and approaching version 1.0
I agree with the sentiments above - this is really impressive and nice to use! It maybe nice to have the option to switch to a "dark" theme? Not sure how easy the following is to implement, but my ideal behaviour for the Term window would involve keeping the session history faithful to what was originally executed - as well as allowing lines to be edited/re-run. To expand on that ... currently it is possible to edit already lines in the session history that have already been executed sentences/lines (or output lines that have been generated) in place, and when you press "Enter" on an edited (or unedited) line it is copied to the bottom of the Term window to where it can be executed (potentially after further editing). My preference would be that the original line above in the Term window would at that point revert to its original state (i.e. the sentence that was previously executed or result that had already been generated.) In my opinion this would be a desirable improvement for the JQt interface too, but as mentioned to start with, I'm not sure how easy it would be to implement.

Congratulations, that is very nice. I particularly like the inline graphs. The rather immediate failure with Chrome on Android remains. As before it works correctly with Firefox.

Re: [Jgeneral] J Playground - Major upgrade announcement and approaching version 1.0
Just kicked the tires of the latest playground iteration. I'm impressed. The playground has morphed into a very respectable little J GUI.

Re: [Jgeneral] J Playground - Major upgrade announcement and approaching version 1.0
Raul, thanks for the feedback. My thinking is that in the near term we'd overwrite the deployment of the proof-of-concept version with the new version and copy as needed to preserve the URLs. The new playground upgrade supports the #code= mechanism so it should be just a matter of changing the makefile to also duplicate /bin/html2/index.html and supporting assets to /bin/html/emj.html (not tested). I will test it before we do this and wait a few days to see if anyone else has any must-haves from the proof of concept before we make the switch. I'd prefer to retire the proof of concept sooner than later to reduce any relearning people have to do.

We have some use of urls linking to the proof of concept version. These were largely proof of concept urls, using the #code= mechanism. I hope we can leave these in place for at least a short time after the canonical version is deployed. Thanks, -- Raul -- For information about J forums see http://www.jsoftware.com/forums.htm
[Jgeneral] J Playground - Major upgrade announcement and approaching version 1.0
The J Playground is a way for users to play with J in their browser without installing any software. It provides a low barrier to try out J and get a feel for the language. It also provides a low barrier for sharing code by generating a URL that can be shared (permalink). The vision is for wiki to have some pages that point to the playground to create an interactive way to learn and experiment with J code. There is a new version of the J Playground available at https://jsoftware.github.io/j-playground/bin/html2/ . It uses prior work in 2018 from Jsoftware Inc (chris burke, possibly others) which was shared to create a big leap forward in the user interface.
