Issue

Hello, I'm new using CherryTree, I just downloaded it yesterday and I wanted to test it's features, I tried to test the code box and see if it would work. When I tried to run a simple Hello world! program in Python3 with the internal terminal it seems that somehow the code hangs on and I can't see any output (note that I tested it without the internal terminal option and it worked perfectly), I just see the command that is put into the Xterm terminal, which is the default one: python3 <tmp_src_path>. Just in case, in the preferences section I also have the default command which is: xterm -hold -geometry 180x45 -e "<command>" &

I also noticed that when I run the program with the internal terminal and I don't see any output, if I press the reset button the program tries to kill a process that apparently doesn't exist, my computer starts doing noise and some programs don't work properly, for example "Screen" which is a terminal emulator / multiplexer just like XTerm.

External terminal (Works)

Internal terminal (Doesn't work)

At this point I'm honestly clueless of what could cause the error and how could I fix this, if I'm being dumb and missing something silly I'm really sorry for the waste of time, any suggestions / ideas / instructions to fix this error would be appreciated.

Thanks in advance and happy new year.

Hello @Fran-P-github and happy new year to you.
Can you specify how you installed cherrytree?
e.g. ppa/snap/appimage/flatpak/...

[Fran-P-github]

Hello @giuspen I installed cherrytree following the Ubuntu instructions in the readme file, I copied all the commands to install the dependencies and documentation, and compile and run cherrytree. I'm not really sure which type of installation that would be called.

[giuspen]

Ok. Could you try to download and run the AppImage from https://www.giuspen.net/cherrytree/#downl and report if it behaves the same?

[Fran-P-github]

Sure, I downloaded the AppImage, executed it and it behaved exactly the same.

[giuspen]

Could you temporarily restore the default shell in your system (I suppose dash or bash) and try again? I will also try zsh to see if that is causing the issue but I'm having some connectivity issues at the moment

[Fran-P-github]

I just changed the default shell to bash and now the internal terminal works perfectly! The reset button also works.

[giuspen]

Ok great I will push something later or tomorrow that I would like you to try after restoring your favourite shell zsh. I'll let you know when I push the change

[Fran-P-github]

Sure @giuspen, thank you so much for your time and help.

[giuspen]

Thanks to you for reporting @Fran-P-github . I pushed a commit that fixed the issue for me after I also tried to use zsh and the integrated terminal wasn't working anymore (it didn't hang for me though).
It would be useful if you could git pull, rebuild and let me know if it works for you as well with zsh set as your default shell.

I rebuilt cherrytree and the integrated terminal with zsh now works!! But, (I want to mention it so you know, but I don't pretend you to fix it because the main issue now works fine) I think due to the package "powerlevel10k" that I've installed, which uses its own characters and colors doesn't work and ends showing the code that it should use to work, so it looks like this:

How it should look:

How it looks in the integrated terminal:

But of course, again, I don't pretend you to fix this because it works perfectly, I just want to report it so you know about it.

Edit: Never mind, I opened cherrytree again and now the terminal doesn't output all those characters.
Thanks again for your help by the way.
