[Packaging] Provide flatpak package

[phw]

I made an attempt to provide a Flatpak package for your excellent NaSC. The build files are available at https://github.com/phw/nasc-flatpak

The build is currently fine, but it requires some patching (see the patch files in the repository):

1. Most important is patching of the app ID from com.github.parnold-x.nasc.gschema.xml to com.github.parnoldx.nasc.gschema.xml (without the dash). Flatpak doesn't allow the dash here, I filed an issue to ask on clarification on https://github.com/flatpak/flatpak-builder/issues/37 .
2. lib dir path for qcalculate, would be solved by https://github.com/parnold-x/nasc/pull/57
3. Hard coded template path for qcalculate

The last two issues should be solved upstream here. For the first issue we maybe need to keep the patch.

One remaining issue that it fails to update the exchange rates on startup. Not sure why, I experimented with --share=network without luck.

I would like to submit this to flathub.org if we get the issues above sorted out. If somebody wants to test this locally you can build a local package by cloning the repository and run:

flatpak-builder --repo=repo com.github.parnoldx.nasc com.github.parnoldx.nasc.json --force-clean
flatpak build-bundle repo nasc.flatpak com.github.parnoldx.nasc
flatpak install nasc.flatpak

Then run it via the desktop icon or from command line:

flatpak run com.github.parnoldx.nasc

Cool. Thanks. Hope I get time this winter to rewrite some parts.

1. Mhh. The elementary houston appstore build thing enforces these RDNN. Not entierly sure if it's also the case with the gschema but I would prefer to keep it consistent.
2. Merged. Hope launchpad builds now with your tip.
3. I removed the template and the style dir can now be set in the CMake.

Great, that's looking good :) I just submitted a final pull request, then I think this is good to go.

About the app ID: Yes, I would leave it as is and we just patch it for flatpak. We have conflicting restrictions here, and changing the app ID is not an option with Elementary anyway ( this troubles me in one of my own apps, too). If you are interested they are tracking this on https://github.com/elementary/houston/issues/436

Awesome app by the way, I had been looking for this for a while. I often fall back to pen and paper for things like this, but this is just great. Especially that you can give it away as PDF afterwards. Only thing I would love to see is some plotting capabilities :)

[parnoldx]

Happy to see that it's useful for you. Main problem for plotting is how to integrate this good regarding to UX.

Have been using the flatpak version over the last days, working good for me. If you are ok with it I would propose this for flathub.org once you make a new stable release.

[parnoldx]

Im OK with it. I will trigger a new appcenter release. This should also make a release.

Submitted to Flathub at https://github.com/flathub/flathub/pull/128

[parnoldx]

Great. Thank you.

As soon as this is published I will provide a pull request for the README with install instructions.

Most important is patching of the app ID from com.github.parnold-x.nasc.gschema.xml to com.github.parnoldx.nasc.gschema.xml (without the dash)

I'd recommend com.github.parnold_x.nasc rather than com.github.parnoldx.nasc. There could be a Github user named parnoldx, but there can't be one named parnold_x because Github doesn't allow underscores in usernames (they are syntactically the same as Internet hostnames, so that things like parnold-x.github.io can work).
