flatpak_demo VS flatpak-builder-tools

I worked on https://github.com/fyne-io/flatpak_demo a while back. Hopefully it might be somewhat useful.

As you say, I am not suing the Wayland socket. The toolkit can either be built with only X11 or with only Wayland (the latter not being more than an alpha) and I’m building with only X11. The spec that I’m using: https://github.com/fyne-io/flatpak_demo/blob/main/io.fyne.flatpak_demo.yml

I was having the same issues as you and I put together this demo project to help others where I struggled. It’s not doing anything with Python, but I hope that it might at least get you on the right track. https://github.com/fyne-io/flatpak_demo

While it isn’t directly Rust code, I think you could translate the Flatpak spec relatively easily and switch out to the the free desktop Rust extension. This repository should contain a lot of data that might be useful: https://github.com/fyne-io/flatpak_demo

Setting the build configuration for a module with things like type: autotools, type: cmake-ninja, or type: meson will add the necessary options automatically. Likewise, helper scripts like flatpak-pip-generator will generate manifest fragments containing the necessary prefix-specifying arguments.

There's also this pull request https://github.com/flatpak/flatpak-builder-tools/pull/347 that would add an --ignore-installed= option to flatpak-pip-generator.

Yeah, turns out I had to do something similar to this. flatpak-dotnet-generator proved pretty useful, even if the README was a bit out of date.

If you want it automated, for most packages you can use flatpak-pip-generator

The first issue I had was working out how I add PyPI packages as deps, then I was pointed towards flatpak-pip-generator which generates JSON files that you can add as modules. That works fine:

For packaging with local cache and without networking, use the flatpak-go-get-generator.py from flatpak-builder-tools. I didn't have much success recently with go-get generator, so I'm not sure if working correctly, or it's just me doing something wrong.

I am trying to install `flatpak-pip-generator` found in the link here. It looks like it is part of the `flatpak-builder` package but I have that installed and I can't seem to use the pip-generator. I run the command listed in the readme `flatpak-pip-generator --requirements-file=/the/path/to/requirements.txt --output pypi-dependencies

That one page in the docs does mention that tricky things like dependency resolution have to be done in advance, but support for building that dependency resolution is at best officially unsupported. There's a git repo dedicated to scripts to do this sort of thing but:

It would be nice to see some Crystal apps on flathub (I believe Hashbrown is the only one at the moment). A crystal sdk (like rust's) and a shard builder tool to generate the shards automatically would greatly improve the experience, if anyone is up to doing them.
