clipboard partitioned between CudaText-Qt flatpak and rest of system

[chaserene]

CudaText-Qt flatpak 1.212.1.4--1.214.5 (at minimum, maybe from even earlier)
GNU/Linux Debian 12 + Gnome + Wayland

it's as if CudaText uses a separate clipboard from the rest of the system. in both "partitions" I can simultaneously have different content on the clipboard and insert it there, but I can't copy/paste content between the two in either direction.

this used to work in an earlier version in the same environment.

Can't reproduce on Plasma+Wayland, by copying and pasting with Ctrl+C, Ctrl+V. Can copy from Cudatext to any other application (tried Firefox(Flatpak) and Foot) and back again. Will try in a Gnome VM later.

Highlighting text in Cudatext doesn't let me middle-click-paste it in another app, but I don't think that's ever worked. I can highlight text in another app and middle-click-paste it into Cudatext though.

This mentions the option which must be used:

Even with these options in user.json:

  "mouse_middle_click" : 2,
  "auto_copy_clp": true,

I can't select text in CudaText and middle-click-paste to another app. I still have to copy with Ctrl+C.

It also doesn't work with the CudaText qt5 AUR, or the gtk2 AUR.

But this is a different issue so probably shouldn't go off-topic about it here.

Even with these options in user.json:
"mouse_middle_click" : 2,
"auto_copy_clp": true,

2nd option value is wrong. It must be string of few chars:

default.json:

• if 'c' in value: Copy to usual clipboard (the only possibility on Windows).
• if 'p' in value: Copy to Unix 'primary selection'.
• if 'm' with a following number in value: Limit the selection length, in bytes (suffix "k" is not supported here). Default is 500000.
• Example value: "pm10000".

Got it thanks, it's working now (in flatpak).

@JordanL2 Can you try to repro it on user's config:
GNU/Linux Debian 12 + Gnome + Wayland
?

[JordanL2]

I'll try to set up a VM at some point, yes.

it is not the issue of my program. converted topic to 'discussion'.
