[cantor] [Bug 434271] Plotting doesn't work with octave 6.2
https://bugs.kde.org/show_bug.cgi?id=434271 --- Comment #2 from Nikita Sirgienko --- How you get Octave 6.2? Is it from apt packages, builded manually or it from some container package system like snap? Because if you get octave 6.2 from snap/flatpack or any other container technology, when you should add some additional parameters to container, otherwise the octave will be too isolated and cantor won't able to got any images for plot due filesystem isolation. You can check this bugreport to know more about problems (and how to fix them) between Cantor and Octave from container (from Flatpack in this report): https://bugs.kde.org/show_bug.cgi?id=420959 -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=433982
--- Comment #8 from Nikita Sirgienko ---
Well, this is also well known problem, that Octave plotting via ftlk can work
incorrect and hang during plotting in some linux distros. At least in Cantor
for sure.
So I think, you can try to disable "Embedded" option in Octave (but ftlt window
can also hang itself) or run 'graphics_toolkit("gnuplot")' command before plot
command and check, is that solves your problem with hanging. And if it have
solves the problem, then you can just add the graphics toolkit change command
in Cantor Octave autorun command, or in Octave startup file itelf.
Additional info about ftlk: On my Ubuntu 20.04 ftlk not working correctly like
from Ubuntu 16.04. In early versions we just always have switched from ftlk to
any other graphics toolki, but Cantor have had some bugreports about this
solution and additional research have showed, that on some distros its work
smooth, so we stop to change toolkit and leave graphics toolkit manipulations
in user's hand.

[cantor] [Bug 432892] Handling user input support
https://bugs.kde.org/show_bug.cgi?id=432892 Nikita Sirgienko changed: What|Removed |Added CC||warqu...@gmail.com --- Comment #1 from Nikita Sirgienko --- Hi Because of how Cantor works with Octave in this moment (via stdin/stdout actually) - the "input" function and other related with user input don't work at all I think. This is related that Cantor positioned as REPL - and input functions more useful in scripts, so because of lack developers Cantor haven't support this functions. Actually, there are some workarounds - instead of control Octave worksheet via intput, just control it via variables. It's not very convenient sometimes, but at least it is working solution. Autoevaluation option in Settings can help with this logic. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=430045 --- Comment #8 from Nikita Sirgienko --- Yes, the colorful output very useful, thanks And I have now an idea - do you have installed system Cantor from fedora repos, right? It is important, because I see this paths in your plugin loading output: dir: "/usr/lib64/qt5/plugins/cantor/panels" dir: "/home/jjhough/development/cantor/build/src/cantor/panels" So, given a reported zero-function call issue, I just start think, that your builded Cantor 20.11.80 on startup just loads plugins from system Cantor 20.08.01 from directory /usr/lib64/qt5/plugins/cantor/panels. Because in this case, the zero call is easy to explain - Cantor 20.08.1 plugins haven't this function, this is have added recently. It can happens, because Cantor actually don't have plugin version checking (which is an issue, on which I will take a look soon) So, can you uninstall system's Cantor, re-run install step on your manually builded Cantor and try to start again? -- You are receiving this mail because: You are watching all bug changes.

[cantor] [Bug 425695] Julia backend does not find sys.so
https://bugs.kde.org/show_bug.cgi?id=425695 --- Comment #1 from Nikita Sirgienko --- Well, I now understand, what cause the problem. Cantor Julia backend uses Julia C API and this API requests path to some internal file (the "sys.so" file, which you mentioned before). Julia also provide method for getting path (but relative) to this file. Cantor, using information from settings, create absolute path and pass the path to julia code. The problem is, that cantor-backend-julia have been builded with system julia (I suppose, there is package "julia" in KDE Neon repos). But you pass path to local installation from jill. And relative paths to this internal file don't equal. Cantor julia backend uses "../lib/x86_64-linux-gnu/julia/" from system julia installation (from system library libjulia.so, I suppose), but for in-one-dir julia installation from jill you actually need a path "../lib/julia" (and if you manually build Cantor with Julia backend for this jill installation, then this proper path will be used and passed from Juila C API). But I have added some code for working with situation like this, so it will work in future Cantor versions. And have a more proper problem message, if there is a problem with this internal file. -- You are receiving this mail because: You are watching all bug changes.

[cantor] [Bug 422411] Fail to create symbolic variables
https://bugs.kde.org/show_bug.cgi?id=422411 Nikita Sirgienko changed: What|Removed |Added Status|REPORTED|RESOLVED Resolution|--- |UPSTREAM CC||warqu...@gmail.com --- Comment #2 from Nikita Sirgienko --- I don't think, that this is Cantor problems, because of your python trace the root of problem is Octave(Sage) itself. As I see, you use Manjaro, right? Manjaro, as based on Arch Linux distributive, uses rolling release scheme - for providing latest program versions. So, I suppose, that your sympy packages have been updated recently, but without proper Octave (Sage) updates. It actually, typical problem of Manjaro - problems with packages like that (and the reason for stable distros like Ubuntu LTS to exists). So, the problem is that, then you run `syms x` Octave (or Sage), as SymPy user, try to use attribute `integer_types` from `sympy.core.compatibility`, but the attribute was deleted since SymPy 1.6 , so Octave code for using sympy have failed and module can't be used, so symobolic variable can't be created. I have recomend go to Octave/Sage bugtracker and report problem there, with this python trace message. Or you can just wait some days - I don't think, that you are the only user of symbolic packages, so maybe the problem already reported and will solved in near future sage/octave packages updates. -- You are receiving this mail because: You are watching all bug changes.

Yes, this is correct, and this is actually how new code works.

I don't think, that Cantor as flatpak can be usable, because Cantor needs executable and filesystem access from host and this is not very good working in flatpak. Also, I suppose, you point to your script, that you have mentioned before, rigth? ``` #!/bin/sh exec /usr/bin/flatpak run --branch=stable --arch=x86_64 --filesystem=/tmp org.octave.Octave "$@" ``` I have reproduce this conditions (flatpak Cantor and this script) and well, the problem is, that inside flatpak package path /usr/bin/flatpak is invalid, so Cantor just print me error from this sh script. But I suppose, we still need a code for notice user, if Octave executable finishes suddenly, like in some other backends. > First, I don't think the user needs to know about > /tmp/cantor_octave_plot_integration_test.txt, just telling that access to > the /tmp was not granted would likely be enough. But that problem is more complicated and there are some possibilityes: Octave don't create this file, Cantor haven't permissions to read /tmp, etc. So, because of that the message have so inconcrete text. -- You are receiving this mail because: You are watching all bug changes.

Nodejs no help in this situation at all, because the main limitation is that Cantor, without web engine, can't fully render (I mean, from text form to content, visible for user) HTML+CSS. You have been mentioned Typora, but key component of supporting css styles is that Typora application is actually a browser (chromium, to be more precisious, - Typora is based on Electron framework). And because of fully support of HTML+CSS - Typora can have css style for Markdown, and how it manage the styles - via javascript, or something else - is not very important in this situation. Also, I haven't been mistackend, QML can do only what Qt can do because it is just an another form of UI representation: one form is ordinary (for Qt apps) ui files (and ui files is just a XML) and another form is a more css styled QML markup. -- You are receiving this mail because: You are watching all bug changes.

So, i think, flexibility of Jupyter/Kaggle (with possibility to change view of, well, all existed elements via custom css). So, I don't think, that your request is fully possible. All of this castomizatio comes from flexibility of HTML+CSS, which used in Jupyter and Kaggle. I am not sure (we still considering using qt web engine in Cantor), but I think, that CSS Markdown styles don't possible in Cantor on this moment- this will work only with fully featured web browser. Converting worksheet to Markdown is theoretical possible feature, but this is a lot of work and I haven't seen a huge request for this feature, so I don't think, that we will implement this soon.

[cantor] [Bug 420960] Startup script is not applied
https://bugs.kde.org/show_bug.cgi?id=420960 --- Comment #4 from Nikita Sirgienko --- (In reply to avlas from comment #2) > I confirm that .octaverc is executed at startup (the paths that I added > there are visible in Cantor). However: > > - Cantor executes some code afterwards and overrides its content, for > instance: I set as specific graphics_toolkit qt, yet once I check it in > cantor it says gnuplot and I need to specify it again manually in each > session. Yes, I have been checked code, and Cantor really set gnuplot as graphics toolkit, when integrated graphics enabled. But you actually haven't need to change it to 'qt' manually - use autorun scripts from Octave settings. I have been add example (attachment #1). > - Octave's workspace at startup is not initially seen in Cantor workspace. > For instance, I set a variable in .octaverc like this `x = 2;` and it does > not appear in Cantor workspace, but if I then type in the console `x`, > Cantor correctly returns `2` at the time `x` and its value is added to the > workspace. Is you write 'x' in first executed entry? Because Cantor update variable list (variable manager) only first executed entry. For example, my .octaverc works as expected, see attachment #2 > So, can we make .octaverc the last bit that is executed at startup and have > Cantor display Octave's initial workspace? .octaverc can't be executed before Cantor startup because, Cantor init used --eval octave option. But I think, Cantor can improve currect behaviour, because the idea of changing graphics toolkit to gnuplot is avoiding default fltk, which can freeze octave program (and Cantor too) at all. So, instead of current "always change toolkit" we can use "change toolkit if fltk" and I think, this will be solve your problem, because you use 'qt' toolkit, not 'fltk' toolkit. > Also, I cannot confirm that the script I configure in cantor octave backend > settings is executed. Following the example above, I set a file in there > where I have `x = 2;` and when I test it in Cantor, it says x is undefined, > unlike when I do the same in .octaverc. Well, this is strange. Do you sure, that after writing "x = 2;" you have pressed "Add" button? Because this is needed for actual adding script to autorun, see my attachment #3 -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=420708 Nikita Sirgienko changed: What|Removed |Added Status|CONFIRMED |ASSIGNED --- Comment #10 from Nikita Sirgienko --- Well, I think, I known the problem. Looks like one of library (image library), used by Cantor, named 'LibSpectre', broken. So, when Cantor try to use this library, the library just have crashed and this is crashes Cantor too. This problem have already discovered on openSuse, but now we know, that Manjaro is damaged by this bug too. In this situation, I usually have recommends to disable integrated plots (them will just appears in separate window instead of Cantor window), but because of another bug in 20.04 (already fixed, but the fix will appear only in 20.04.1 (after May 11, according KDE scheldure, but I haven't known a lot of about Manjaro packages sheldure)), this strategy won't work in the Octave backend until 20.04.1 I also have plan to add some settings for the Octave backend (allow force use a png format for plots, which less functional, but don't use libspectre) , which will also allow to avoid libspectre problem, but this also will be available only after 20.04.1 -- You are receiving this mail because: You are watching all bug changes.
