Sync with ownCloud

[jancborchardt]

Hey @lwindolf :)

It would be cool if Liferea would support sync with ownCloud next to The Old Reader and Tiny-Tiny-RSS.

ownCloud has a News app: http://apps.owncloud.com/content/show.php?content=158434
And that News app has an API: https://github.com/owncloud/news/wiki/API-1.2

There’s already great sync clients for Android and iOS, so now it would be cool to have one for Linux. :)

This would really cool. As an owncloud user i'd like to sync to a desktop application and liferea seems to be the perfect solution :)
👍

Similarly, I think this is a necessary next step for Liferea.

However, this was addressed and shut down previously:

Hi guys, my time doesn't allow to build OwnCloud support. Someone else has to do it. Sorry!

Please contribute!

If I find time I'll isolate the node source interface into an example plugin so it can be easily implemented in any scripting language without C knowledge.

I've started working on this. Contributors are welcome: https://github.com/6ahodir/liferea-owncloud-news

@6ahodir awesome! Feel free to spread the word on the ownCloud users/developers mailing lists. :)

[lwindolf]

@6ahodir Great to hear. If you need help with the liferea code base please drop a mail.

@jancborchardt, thanks for the heads up.
@lwindolf, thanks for offering help. I will definitely ping you soon. ;)

@6ahodir is there already something that works and I can try?

[kodchi]

@cosenal, unfortunately, no. But keep an eye on the repo, hopefully we'll have something working in a couple of weeks.

@6ahodir: With above change a new plugin interface is exposed allowing to register plugins providing new "Sources". The plugin boiler-plate would look like this:

from gi.repository import GObject, Peas, PeasGtk, GLib, Gtk, Liferea
class OwnCloudPlugin(GObject.Object, Liferea.NodeSourceActivatable):
  __gtype_name__ = 'OwnCloudPlugin'

  object = GObject.property(type=GObject.Object)

  def __init__(self):
    # Setup a feed subscription type (for updating single feeds)
    self.fst = Liferea.subscriptionType()
    self.fst.prepare_update_request = ...
    self.fst.process_update_request = ...

    # Setup source subscription type (for updating the list of feeds)
    self.sst = Liferea.subscriptionType()
    self.sst.prepare_update_request = ...
    self.sst.process_update_request = ...

    self.nst = Liferea.nodeSourceType()
    self.nst.id = 'fl_owncloud'
    self.nst.name = 'OwnCloud'
    self.nst.capabilities = Liferea.NODE_SOURCE_CAPABILITY_DYNAMIC_CREATION + 
                                      Liferea.NODE_SOURCE_CAPABILITY_ADD_FEED +
                                      ...
    self.nst.feedSubscriptionType = self.fst
    self.nst.sourceSubscriptionType = self.sst
    self.nst.method1 = ...
    self.nst.method2 = ...
    ...

  def do_activate (self):
    Liferea.node_source_type_register (self.nst)
