Syntax Highlighting is broken, color themes not displayed. about cherrytree HOT 13 CLOSED

I see you are using Ubuntu studio and a KDE desktop, that may be the reason I'm not seeing the issue, as I'm on a GTK desktop.
I suspect some GTK needed stuff is not in the AppImage bundle, in fact I see errors loading a couple of GTK modules.
I will try to reproduce myself on a KDE desktop.

from cherrytree.

Turns out the issue is visible also on a GTK desktop. I wasn't seeing it because I had the cherrytree dependencies already installed. It's visible for example also on a clean Ubuntu (Gnome, GTK) 24.04 installation. I'll see if I can find out which library files are not copied over from the AppImage GTK script

from cherrytree.

I believe installing this will do for you, please confirm:

sudo apt install libgtksourceviewmm-3.0-0v5

from cherrytree.

I believe the issue is now fixed.
It would be very useful if you could confirm it:

1. sudo apt purge libgtksourceviewmm-3.0-0v5
2. sudo apt autoremove --purge
3. check that you do see the issue again with the AppImage v1.1.2
4. download
   https://www.giuspen.net/software/CherryTree-1.1.2+7-x86_64.AppImage and verify that there is no issue there

from cherrytree.

I can see that on 24.04 the AppImage doesn't even start, while runs correctly on 20.04.
I will investigate.

from cherrytree.

On 24.04 the appimage doesn't start because libfuse.so.2 is not found.
Running it from the terminal gave me that info so it was fixed after installing libfuse2t64.
I then tried on a 22.04 and it worked normally.
Can you try to run it from the command line and report if any error is printed?

Can you try to run it from the command line and report if any error is printed?

Thanks, I shall try that.

Edit:

I tried it, the application behaviour is same (expectedly). The following is printed in the terminal:

Thank you very much.

from cherrytree.

I wasn't seeing it because I had the cherrytree dependencies already installed

What are the package names of these dependencies?

Of course, a self-contained Appimage coming with these is the ideal solution, but as a temporary fix, could the problem be solved with sudo apt install <packagename>?

from cherrytree.

Correct @keyboard-penman installing the dependencies will fix the issue, if your distribution is too old though you may find an old package with incorrect dependencies.
I can paste here later the current dependencies on Ubuntu 22.04

from cherrytree.

sudo apt install libgtksourceviewmm-3.0-0v5

Yes, it did indeed work. Thank you, again.

from cherrytree.

I believe the issue is now fixed. It would be very useful if you could confirm it:

1. sudo apt purge libgtksourceviewmm-3.0-0v5
2. sudo apt autoremove --purge
3. check that you do see the issue again with the AppImage v1.1.2
4. download
   https://www.giuspen.net/software/CherryTree-1.1.2+7-x86_64.AppImage and verify that there is no issue there

Just did this.

Purging ibgtksourceviewmm-3.0-0v5 did cause the error again.

And it was fixed with the new Appimage.

Problem solved, it appears :)

Thank you so much for addressing this.

from cherrytree.

Excellent, many thanks @keyboard-penman for reporting and verifying the fix
