Re: digikam 6.0.x and kipi-plugins

[Rex Dieter-2]

I saw some recent posts about refactoring kipi-pugins and that digikam-6.0.0-beta3 doesn't appear to include any plugins at all.  Was the non-inclusion intentional?  I didn't see it mentioned in any of the beta release notes.  If so, how are distros expected to handle this?  

Obviously, dropping these means a significant reduction of functionality for other kipi-plugin consumers (like gwenview).

Hi,

Yes for the 6.0.0 release, libkipi dependency is removed. This is the plan to make digiKam less KDE dependent application.

For the end users, this will not changes something, as all older tools still here, but not as plugins. For packaging, this will more simple due to dependencies simplification.

For 6.1.0, new plugin interfaces  (note the "s") will be ready to use. This have not been ready for 6.0.0. These interfaces will be pure Qt5 implementations, as Marble project do.

6.1.0 will introduce more : 3 plugins interfaces for digiKam as generic, editor, and batch queue manager (Showfoto will use 2 first ones). The implementation is mostly done to 85% in a dedicated branch.

Later we plan more plugin interfaces : image loaders, maintenance, and perhaps database.

External contributions will be possible with open API using only digiKam headers.

Voilà for the technical sumary.

Just so we're clear here.  It sounds like you didn't explicitly address my "dropping these means a significant reduction of functionality for other kipi-plugin consumers (like gwenview)" comment.  

So other kipi-plugin consumers (like gwenview) will be losing functionality?  If so, I may have trouble justifying providing such a digikam update in stable distro releases.

Or are other existing libkipi apps being adjusted to use these newer digikam interfaces too?

No. kipi-plugins still here, are libkipi. just digiKam do not use libkipi anymore with 6.0.0.

 

Or are other existing libkipi apps being adjusted to use these newer digikam interfaces too?

Good question.

The goal about the new digiKam start, after 2 years of development (last stable was 5.9.0, but 6.0.0 have been started 2 year ago), is to rewrite the whole plugins interface.

In fact, in next digiKam 6.1.0, we will come with 3 levels of plugins : generic (as kipi), but also Editor (for digiKam image editor and Showfoto), and Bqm, for the Batch Queue Manager.

We have something like more than 100 plugins now...

All plugin mechanisms are inspired from Marble stuff. It use a pure and simple Qt5 API. All plugin types use shared components from digiKam core. Plugin types share same classes internally, and this prevent code duplication and permit to implement a new plugin very quickly without to re-invent the wheel.

Later 6.1.0, we will create more plugin types step by step, as face engines, maintenance tools, image loaders, etc... This will take time, but it's the plan to make all lead features as plugins in digiKam. This way permit to isolate well all digiKam components which will be more easy for external contributor to patch and create new ones, without to touch internal implementations.

So to come back about the sharing plugin with other KDE applications. why not, i don't say no, _but_, the plugin interface still in digiKam core. External KDE applications who want load plugins will need to use digiKam core, as extra dependency.

Voilà for some technical details, and the plan...

That's good to hear.  Where is kipi-plugins then? It seems not present in the digikam-6.0.0-beta3 tarball at least.

hi,

Ah you want mean if the source code still released in digiKam. Well no, it must be released as a separated package now, as libkipi in fact.

Plugin types share same classes internally, and this prevent code duplication and permit to implement a new plugin very quickly without to re-invent the wheel.

Later 6.1.0, we will create more plugin types step by step, as face engines, maintenance tools, image loaders, etc... This will take time, but it's the plan to make all lead features as plugins in digiKam. This way permit to isolate well all digiKam components which will be more easy for external contributor to patch and create new ones, without to touch internal implementations.

So to come back about the sharing plugin with other KDE applications. why not, i don't say no, _but_, the plugin interface still in digiKam core. External KDE applications who want load plugins will need to use digiKam core, as extra dependency.

Voilà for some technical details, and the plan...

Thanks, any estimate when a standalone kipi-plugins release may happen?

hi,

Ah you want mean if the source code still released in digiKam. Well no, it must be released as a separated package now, as libkipi in fact.

That's good to hear.  Where is kipi-plugins then? It seems not present in the digikam-6.0.0-beta3 tarball at least.

No. kipi-plugins still here, are libkipi. just digiKam do not use libkipi anymore with 6.0.0.

 

Or are other existing libkipi apps being adjusted to use these newer digikam interfaces too?

Good question.

The goal about the new digiKam start, after 2 years of development (last stable was 5.9.0, but 6.0.0 have been started 2 year ago), is to rewrite the whole plugins interface.

In fact, in next digiKam 6.1.0, we will come with 3 levels of plugins : generic (as kipi), but also Editor (for digiKam image editor and Showfoto), and Bqm, for the Batch Queue Manager.

We have something like more than 100 plugins now...

Well I don't know.

In fact a request must be open in KDE Phabricator to system admin team. As they are busy to migrate KDE git server step by step to Gitlab, i doubt that it will done easily from now.

We are fully detached for kipi development now, but you can ask to a team which still use it, as KPhotoAlbum or GwenView.
