Review of Krita snapcraft.yaml

snapcraft
1

Good day everyone,

Just working on the Krita snap, and I have a local build/install working (so far) without issue.

I was hoping to get a sanity check on my YAML file as I mostly at this point took the existing work (and version) and got it running again. I’m just wondering if there are any optimisations or more current ways (as I know it is still under heavy dev) that some of the more experienced snapcrafters might be able to point out.

If the YAML file looks okay, I’ll get it pushed out for testing after a few more tweaks. (such as current version, confinement mode, etc.)

Thank you in advance!

Could you use the kde-frameworks-5 snap rather than bundle all that KDE stuff?

3

I suggest you add ‘desktop’ and since you have unity7, ‘desktop-legacy’. See The desktop interfaces

Thanks! I added that in!

I was reading up on this and came across this blog post:

Does anyone have any idea if this is still considered current (year old)? I’ll have a go with that article and see how far I get.

Alright, attempting to update and build with the kde-frameworks-5 snap (at the above URL).

I ended up at:

Looks like the QT section and kde-framework-* stuff are conflicting. Suspect the QT stuff is included as part of the framework (to a degree).

Snapcraft offers some capabilities to solve this by use of the following keywords:
    - `filesets`
    - `stage`
    - `snap`
    - `organize`

Learn more about these part keywords by running `snapcraft help plugins`

I’m continuing to read up, but I am wondering if the right rabbit hole to go down is to remove the QT section and work through from there or continue to investigate the above plugin help docs…

EDIT - Yup, I’m stumped. I suspect it has to do with filesets, but my non programming head isn;t quite wrapping around it.

Small update to those who are interested. Been working with the devs (Krita). They have V4 dropping soon. The idea is to get this working in V3 without major changes. Then V4 work will start.

Take a look at https://lxr.kde.org/source/playground/packaging/snapcraft-kde-applications/kstars/snapcraft.yaml for inspiration. Specifically the part named kde-frameworks-5-dev.

Maybe @sgclarkkde can help you get started.

Thanks @sergiusens!! Appreciate the feedback.

@sgclarkkde / @sergiusens

Overall I think I’m on my way. BUT - the biggest thing is getting some of the needed (as per the build instructions) build-packages in on a system that is 16.04.

From reading, I know we do not want to get packages from a PPA (kubuntu backports seem to have most things I need).

I have converted the snap over to use the kde-framework-5-plug method, but need to still get the build packages in.

11

Oh? Lots of your build-packages look like KDE Frameworks 5 things (though I don’t know if they’re provided in the content snap in the way you want or not), could you post an updated snapcraft.yaml or maybe host the code online (GitHub?) and link to that? :slight_smile:

Hey @Ads20000 - sorry for the delay in my reply. Pulled in another direction.

I just cloned over the snapcrafters repo and did the initial commit.

https://github.com/bashfulrobot/snapcrafters-krita

This is not building yet, as I just wanted to get the code in.

You can ignore the shell files. I just push my work into a local LXD container to keep iterating and testing. and the snapcraft-orig.yaml file is just a reference to the original that used to work on older versions.

I’ll be continuting to work. If anything sticks out at anyone - feedback is appreciated!!!

It refuses to build here.

Failed to get part information: Cannot find the definition for part 'qt'. If it is a remote part, run 
`snapcraft update` to refresh the remote parts cache. If it is a local part, make sure that it is defined in the `snapcraft.yaml`.

Looks like you’re referencing a part called ‘qt’ & one called ‘kdeframeworks’ which don’t exist, but which do exist in the snapcraft-orig.yaml.

14

Hi popey, oops, should have been more clear. Still developing, and was more so meant to link the code up as @Ads20000 had requested. Looking back at it, I had removed it to test something. I’ll update I’m the am :clock130: (1:30am here).

15

Hi, some advance ? do you have date release to the krita.snap? in this version could be configured languages?

16

Hi there. I was working on a V3.x version, but the discussion has come up that V4 might drop in March, so I am evaluating moving onto that version instead. Thoughts? the other thing I am considering is that Krita has the Lime PPA. So maybe a V3.x based on the PPA/ deb (I believe I saw a way that Dan had done with the gnome stack) just to get it out. But they traditionally do not build against 16.04. Just considerations.

17

Can you consider bundle krita with ffmpeg to export images sequence like videos ? this option not come by default and i do not know if this package will have problems with restrictions

18

Is this a part of the core functionality? Amy other external tools?

I’m also curious what the other snap community might suggest for this type of scenario…

19

I also see that there is an ffmpeg snap. I’ll see if there is a way to leverage that.
