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!

Re: [Jgeneral] J Playground - Major upgrade announcement and approaching version 1.0
> 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. 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] JQt install: assertion failure
You should probably remove J902 from that system. Type: which jqt That should tell you how your system is finding jqt. That jqt should be j903 rather than j902.

Re: [Jgeneral] JQt install: assertion failure
To bill lam: Thanks a lot, that problem is solved. To Raul Miller: I ran install-usr.sh (with sudo) before running ijconsole, and it gave this message: $ sudo ./install-usr.sh this script will install j system on /usr /home/razetime/j903/bin done It seems that J902 did not get updated in the process. Running ./jqt.sh from the home folder installation works, but doesn't seem to work as an ordinary command. How do I remove J902 for this?

Re: [Jgeneral] JQt install: assertion failure
It looks like you installed libjqt for j 903 but are running j 902. -- Raul On Tue, Apr 26, 2022 at 5:01 AM Razetime wrote: > > My previous question was already on the forum, but after a search, I was > unable to find this problem (happens on install jpkg *): > Installing JQt binaries... > install libjqt.so to /usr/lib/x86_64-linux-gnu/ > cd "/tmp" && tar --no-same-owner --no-same-permissions -xzf > "/tmp/jqt-linux-x64.tar.gz" && chmod 755 jqt && mv jqt /usr/bin/jqt-9.03 && > cp libjqt.so /usr/lib/x86_64-linux-gnu//libjqt.so.9.03 && chmod 755 > /usr/lib/x86_64-linux-gnu//libjqt.so.9.03 && ldconfi... > update-alternatives --install /usr/bin/jqt jqt /usr/bin/jqt-9.03 903 > update-alternatives: warning: forcing reinstallation of alternative > /usr/bin/jqt-9.03 because link group jqt is broken > Finished install of JQt binaries. > If libjqt cannot be loaded, see this guide for installing the Qt library > https://code.jsoftware.com/wiki/Guides/Linux_Installation > Exit and restart J using jqt > *** next step updates JE > upgrade not required - already current > *** next step creates desktop J launch icons > ~/Desktop folder does not exist for shortcuts > perhaps create ~/Desktop as link to your Desktop folder and rerun > |assertion failure: assert > | assert 0 > When I try to run jqt, I get the following error: > $ jqt > "libjqt.so.9.02" > "could not resolve: state_run:\n\nCannot load library libjqt.so.9.02: > (libjqt.so.9.02: cannot open shared object file: No such file or directory)" > I've installed the packages mentioned over at > https://code.jsoftware.com/wiki/Guides/Linux_Installation (Ubuntu 20.04), > but this issue still persists after a restart. > -- > For information about J forums see http://www.jsoftware.com/forums.htm -- For information about J forums see http://www.jsoftware.com/forums.htm

[Jgeneral] J903 JQt Install Error
I'm trying to install all J903 libraries as per
https://code.jsoftware.com/wiki/System/Installation/J903/Zips, but I get
the following error:
Installing JQt binaries...
install libjqt.so to /usr/lib/x86_64-linux-gnu/
|value error: vsuffix
| echo'cd ',(dquote jpath'~temp'),' && tar --no-same-owner
--no-same-permissions -xzf ',(dquote p),' && chmod 755 jqt && mv jqt
',BINPATH,'/jqt-9.03 && cp libjqt.',suffix,' ',d1,'/libjqt.',vsuffix,' &&
chmod 755 ',d1,'/libjqt.',vsuffix,('Linux'-:UNAME)#' && ldconfig'
How would I fix this problem?

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
