Yep, that sounds right.

In my project, I created 'Client.qml' to use as my python 'API client':

https://github.com/mattaustin/gaussian/blob/qmlexperiment/qml/common/Client.qml

This then gets added to ApplicationWindow, so it's accessible from anywhere:
https://github.com/mattaustin/gaussian/blob/qmlexperiment/qml/silica/main.qml

 What does the Jolla browser or the webview show here?

The Sailfish Browser on the Jolla shows a device pixel ratio of 1.5

 Ahoy Dear Developers,

 Generally there have been some significant backend changes to the QA portion 
 of the Harbour that should permit a smoother submission process.


Great news - thanks!

The first question which I immediately want to ask is if these backend
updates now allow specifying a minimum Sailfish OS version for an
application - and therefore if it is now possible to submit
python/pyotherside applications to the Harbour?

Re: [SailfishDevel] RPM-packaging for Python/QML applications

[Matt Austin]

Hi Osmo,

 Does anyone have an example of RPM-packaging for a PyOtherSide or pure QML
 application?

 I'm not familiar with RPM. In the case of PyOtherSide should I write YAML or
 directly a spec file?


I haven't tried this myself yet, but am interested in any guidelines
that others might have.
From a quick search, it looks like gpodder for sailfish os just
provides the rpm .spec file:

https://github.com/gpodder/gpodder-sailfish/tree/master/rpm


 Looking at a couple non-C++ Sailfish applications on GitHub, I see them
 using minimal C++ ('SailfishApp::main(argc, argv)'). Why such a travestry
 instead of a shell script calling qmlscene or sailfish-qml?

I believe for non C++ apps, we can just call 'sailfish-qml' (qmlscene
is not supported). This has some restrictions - see Mike's response
from last week here:
https://lists.sailfishos.org/pipermail/devel/2013-December/002076.html

Matt.

 Because of the dynamic nature of Python, it's even harder to verify
 apps don't break with OS/library updates compared to native C/C++

 Python 3 is relatively easy to maintain, and apps can then ship
 different versions of modules they need.

Hi Thomas. This is understandable - having Python available at all is fantastic.


 We can of course provide some guidelines for how to best
 package/bundle Python libraries (especially more complicated ones that
 involve C extension modules) into an application's RPM package, and
 make sure the bundling/packaging experience is as good as possible.

Any guides would be very welcome, as I come from a python and web
development background. Packaging is something I don't have much
experience at.


I've started making some general Sailfish  Python Development notes
on the Mer wiki:

Thanks again!

[SailfishDevel] QML only apps: sailfish-qml

[Matt Austin]

Hi sailors,


The Harbour FAQ states in regards to .desktop files:

What do I have to put into the Exec= line?
Exec=$NAME (for Silica applications using C++ and QML) or
Exec=sailfish-qml $NAME (for QML-only Silica applications without an
application binary)


However, I don't appear to have sailfish-qml available:

[nemo@localhost ~]$ sailfish-qml
-bash: sailfish-qml: command not found


And zypper can't find anything which provides it:

[nemo@localhost ~]$ zypper what-provides sailfish-qml
Loading repository data...
Reading installed packages...
No providers of 'sailfish-qml' found.


Is the FAQ out-of-date, or am I missing something which should be installed?


Regards,

Matt

Re: [SailfishDevel] QML only apps: sailfish-qml

 One thing to be aware of is that it doesn't work exactly like qmlscene
 where you can just specify an arbitrary qml file to display, instead you
 have to install your main qml file to
 /usr/share/yourapp/qml/yourapp.qml then run sailfish-qml yourapp.

Thanks Mike! Seems a little strange to be so tightly restricted to the
location of the qml file - makes maintaining a single codebase for
different platforms more difficult - especially with the
harbour-appname too. Maybe I can create a symlink to main.qml.

Cheers,

Do you think it likely that some python libraries are likely to be
considered too?

I'd like to request python-lxml.

I tend to use python-lxml quite a bit in my projects, but this isn't
easily bundled along with a pure-python project, as it builds against
liblxml2 and libxslt.

If not then I guess I'd either have to bundle a built version with my
app (no idea where to begin in doing this though), or switch to a
pure-python html/xml parser.


Thanks!

[SailfishDevel] Correct way of referring to Sailfish

[Matt Austin]

Hi,

Just a small pedantic question - when referring to Sailfish, should I be
using:
1) Sailfish
2) Sailfish OS
3) SailfishOS


Is there any versioning scheme I should also use when I want to say that my
app works on Sailfish?


Thanks,

I had the same issue, and realised that it only happened when I was

I removed this line, and the app/cover seemed to work as expected.
Maybe you're using QGLWidget too?

[SailfishDevel] App feedback / showcase / examples

[Matt Austin]

Hi all,

I just completed my initial porting of Perth Trains over to Sailfish
Silica [https://github.com/mattaustin/fremantleline/tree/development].

The application is not very mature, but is split in to an 'api' and a 'ui'.
I am very aware that the entire project could do with a lot more
improvement, and although I can easily recognise plenty of improvements to
be made in my python/'api' side of the code, I'm much more uncertain/unsure
of the pyside/qml aspects.

I would welcome any criticism/feedback if anyone has the time to spare -
but more importantly I was wondering if there are any particular resources
or lists of community/open source Sailfish apps which I can take a look at?
gPodder is a great and obvious example, and there is also the short app
list on the Mer wiki [https://wiki.merproject.org/wiki/Sailfish] - but is
there any kind of 'announcement' list/forum I can follow which I haven't
yet discovered? I always like taking a look at how other developers have
tackled things.

One issue I have in particular, is that the app freezes as the departure
information for the chosen station is scraped from the website. What would
be the suggested way to tackle this? Do I need to jump in to playing with
python threading, or is there something I can do on the qml side of things
to show a 'loading' indicator? My previous attempts at showing a qml Item
before updating the departurelist model didn't have any effect.


Looking forward to tomorrow's announcement!


Regards,
