Re: [Geary] port to WebKit 2?

Hey everyone,

So we actually didn't do the webkit2 port just yet. We did the native widgets port first so we could minimize the use of the webview. As far as the conversation view goes, I think the only use of granite is because we have an avatar widget in granite trunk (bzr term for master) these days.

This is working very well for us, using only native Gtk widgets. Gtk.CSS is really powerful these days and with a couple revealers and such we still have all the nice animations and features like collapsing and that. We are currently including a basic stylesheet so that it doesn't look too awful in other themes.

We have indeed been trying to migrate code from Geary code style to elementary code style. It just makes things a little nicer for developers at elementary who are bouncing from project to project. I've personally done a lot of work trying to get rid of things like the PillHeaderBar. I think it just makes the code really hard to read and is a bit over-engineered.

We technically have an elementary developer mailing list, but honestly nobody uses it. Everything is done in Slack these days. I've sent invites to Mike and Adam. Let me know if anyone else would like invites. We're more than happy to chat about things that might be useful for you folks.

The really big thing that we've been on lately is actually to port Mail over to an Evolution Data Server backend. We've been doing work upstream on completing GObject Introspection for LibCamel and one of our guys has some ideas about making the API a bit nicer in general. He's had a lot of success pushing branches already, so that's great. One of our other guys is working on a little prototype app before we try to actually make the conversion. You can see the code for that here:

Let me know if you have any questions about Mail and I'll do my best to try to address them :)

I'm CCing Daniel Foré in on this thread so he can chime in; he is more familiar with the Pantheon Mail codebase than I and can probably direct you to the right places. :)

I was thinking GSK/Clutter to be able retain something closer to the
existing look of the conversation view, but I guess that style should
be able to be retained using standard widgets without too many
problems? That certainly seems to be the approach taken by Pantheon
Mail, at least.

Will start looking into it.
