Cudatext: Flatpak

[JordanL2]

I've been working on flatpak-ing this application:
https://github.com/JordanL2/io.github.CudaText-Qt5
I'm using this flatpak'ed version and everything appears to be working.

Only issue I had was the Flatpak org.freedesktop.Sdk.Extension.freepascal SDK uses Lazarus 2.0.12 and that has Wayland issues - when Lazarus 2.2 is released I'll send the SDK dev a PR to update Lazarus.

I think this flatpak config is in a state ready to be submitted to Flathub, if you were keen on the idea? I'd be happy to hand over the repository to you (or you can copy / fork it) :)

BTW, the metadata file needs a description and screenshots to be accepted by Flathub, so I copied the screenshot URLs and description from your website.

[Alexey-T]

Great ! Pls submit it to the Flathub, because I am not expirienced here...

[JordanL2]

No problem :) I've not actually submitted anything to Flathub before, but I'll let you know how it goes!

[JordanL2]

@Alexey-T I don't suppose you have any idea why compiling bgrabitmap for aarch64 fails here?
https://flathub.org/builds/#/builders/45/builds/4157

I'm probably going to skip aarch64 for now and concentrate on x86_64, but it would be good to get it working.

EDIT: Some more info, the Freepascal SDK builds from these sources for aarch64:
https://downloads.sourceforge.net/project/freepascal/Linux/3.2.0/fpc-3.2.0.aarch64-linux.tar
https://downloads.sourceforge.net/project/lazarus/Lazarus%20Zip%20_%20GZip/Lazarus%202.0.12/lazarus-2.0.12.tar.gz

And sets this env var on aarch64:
PPNAME=ppca64

[Alexey-T]

I got the latest bgrabitmap from Github.
I recompiled Cud build-mode 'linux aarch64'. It gave errors but non fatal errors, binary was made.

And you need FPC 3.2.2 if FPC 3.2.0 fails here, maybe

[JordanL2]

Ok, I'll try again when I can update the freepascal SDK.

[JordanL2]

The flathub dev worked it out, we needed to pass --compiler=ppca64 to lazbuild.

[JordanL2]

FYI this is the PR, it's still unmerged due to server issues:
https://github.com/flathub/flathub/pull/2449

[Alexey-T]

Great, thank you! How can I use/install the app from Flathub? I will search for this inf.

[JordanL2]

No, it's not available yet, the PR still needs to be merged to flathub.

[JordanL2]

You can install and run the test build with this command:

flatpak install --user https://dl.flathub.org/build-repo/53745/io.github.cudatext.CudaText-Qt5.flatpakref
flatpak run io.github.cudatext.CudaText-Qt5//test

One of the flathub maintainers is apparently having trouble installing plugins, I'm trying to help diagnose the problem because all the plugins I've tried installing worked...

[Alexey-T]

My Ubuntu don't have the Flatpak, so I will try it but much later. Thanks.

[halfbrained]

I played with this a bit, had no problems, plugins are installing fine

[JordanL2]

Update - It's not been accepted yet, but I managed to get an update the the Freepascal SDK merged so it uses Lazarus 2.2.0-RC1. This means the build now works on Wayland.

[Alexey-T]

Only issue I had was the Flatpak org.freedesktop.Sdk.Extension.freepascal SDK uses Lazarus 2.0.12 and that has Wayland issues - when Lazarus 2.2 is released I'll send the SDK dev a PR to update Lazarus.

As you wrote, you have some PR for Lazarus? why not to post this as an issue to https://gitlab.com/freepascal.org/lazarus/lazarus/-/issues
you can login to GitLab by GitHub account.

[JordanL2]

No, this was for the flatpak SDK - a set of libraries that are made available to the app when it's building, basically. The PR updated the Lazarus version to 2.2

[JordanL2]

It's been published :)
https://flathub.org/apps/details/io.github.cudatext.CudaText-Qt5

This is the repo for further changes, @Alexey-T I'll give you access to it.
https://github.com/flathub/io.github.cudatext.CudaText-Qt5

[Alexey-T]

Great... I will see it.

[JordanL2]

Actually seems I don't have permission to give other people admin access - I don't see the Settings tab. I'll let you know if I figure out how to get you access.

[Alexey-T]

Can I ignore the invite request? I just don't wanna study how that system works. maybe you will support the Flatpak package?

[JordanL2]

Yes no worries I can do that :)

I just updated it to 1.141.0 too.

[JordanL2]

Btw I guess this issue can be closed now.

[JordanL2]

@Alexey-T btw, you can see the stats of downloads of the flatpak here:

https://klausenbusk.github.io/flathub-stats/#ref=io.github.cudatext.CudaText-Qt5&interval=14&downloadType=installs

[Alexey-T]

Thanks.

[Alexey-T]

I guess I will download the Cud from FatHub and test it.

[JordanL2]

Hmm, I'm getting Access Violation popup errors when I close windows now. Also, if I try installing a plugin now, nothing happens and I see an exception in the console complaining about access violation.

I think this occurred with a recent update to Cudatext, because if I roll the version of cudatext the flatpak uses back to 1.140.5, the problem disappears.

The problem occurs with 1.141.0 onwards (I've not tested a non-flatpak version, the AUR only has 1.139.5 available). Also, these deps were updated as new ones were available:

bgrabitmap
ATSynEdit
ATSynEdit_Cmp
EControl

I'll roll the flatpak back to 1.140.5 for now.

[JordanL2]

Looking at the commits between 1.140.5 to 1.141.0, I'm wondering if it's the bookmark file stuff. This issue is most likely caused by it trying to access a file it's not allowed to.

[JordanL2]

Hmm this isn't anything to do with the flatpak sandboxing, when I run the binary (inside the flatpak) directly I get the same error.
