Re: [Announce] modRana: a flexible GPS navigation system
 

An issue on Sailfish OS: volume buttons zoom the Modrana window instead of changing the volume, even when it's not the active application.

Re: [Announce] modRana: a flexible GPS navigation system
 

I finally got to trying the Python Mapnik example, and it seems to be working! :) This is the resulting image from the example, rendered on my N900:
http://modrana.org/images/python_mapnik/world.png

I have encountered a couple of issues I had to fix before I was able to make the image:

Mapnik requiring Property setter on Python 2.5

The Python 2.5 @property decorator does not have the setter yet. This can be faked around by overriding the Python 2.5 property with a newer one before importing the mapnik module:

Mapnik looking for libraries in the wrong path

Next I was getting errors when trying to create the shape data source. From StackOverflow I've found this is caused by incorrectly configured Mapnik lib path. In my case it was expecting /lib/mapnik but the files were in /usr/lib/mapnik and I've fixed this by creating a symlink:

After I did these two tweak I have been able to complete the example and render the world map image. :)

Also even though both can be worked around, it should be possible to fix both at packaging level to make workarounds unnecessary.

Offline map rendering in modRana WHEN ?

Even though this is certainly a step in the right direction for offline map rendering in modRana, it will still take some time. :) The example I've tried is very basic and there might still be some breakage in other more advanced parts of Mapnik I have not tried out yet.

And even more importantly I'll have to investigate what data source to use for usable offline map rendering. The example data source (a single shape file) and style are really simple, but for on the fly rendering on a high zoom level much more data and a much more complicated style will be needed. The data for offline map rendering also needs to be simple to obtain for modRana users. So quite a lot of interesting "challenges" all around. :)

In short, this is moving in the right direction but will need some time. :)

PS.: Thanks a lot to marmistrz yet again for the Mapnik port! :)

Re: [Announce] modRana: a flexible GPS navigation system
 

Where are you suing it - on the N900 or on the Jolla ? and if you are on the N900, are you using the classic (GTK) interface or the QML one ?

Also, what do you mean by getting more clunky - do you mean it is getting slower if you are running it for extended periods of time ?

You are right! :P I was pretty sure I disabled volume key usage when the modRana window looses focus but looks like I forgot to do it. :D Should be easy to fix though. :)

BTW, do you plan to use modRana to show geographic search results with your Saera port on Sailfish OS like back then with Saera on the N900? :)

Re: [Announce] modRana: a flexible GPS navigation system
 

suing :eek: no no
on n900 it gets slow ofen mainly when left in background
one improvment i have found is no tile download failures as of late .
navigating menus is cubersome with up down arrows making them scrollable would be useful
slider or double tap for fast zooming in out
there should be a tile for map switching as its cubersome diving deep in the menu for it
clicking on maps is not possible so most info from osm is not usable as in marble i can click anywhere and select adreess info same for google maps i.e bus stops and such names are not shown only icon
ui style is nice but looks awful not complaining :d i am making a few icons in png if that helps
anyway i think as mapink is progressing these issues can be dealt later on

Re: [Announce] modRana: a flexible GPS navigation system
 

I would like to, yes. How can I communicate with modRana on SailfishOS?

Re: [Announce] modRana: a flexible GPS navigation system
 

CLI argument passing is kinda borked at the moment as sailfish-qml, the "official" Sailfish OS QML application launcher does not forward command line arguments. So maybe chip-in that this missing functionality would be useful for Saera ? ;)

Alternatively some other way could be used until this is fixed, such as environmental variables or DBUS. :)

Re: [Announce] modRana: a flexible GPS navigation system
 

That's weird, I am pretty sure (I don't have Jolla right now to test it) LL's videoPlayer can take filename as an argument and the source code suggests you can pass different arguments, not just the filename:

Re: [Announce] modRana: a flexible GPS navigation system
 

Sure, that's possible if you use your own C++ "launcher" but I'm using the sailfish-qml utility to do the lunching and it does not forward command line arguments (unlike qmlscene, which does forward command line arguments).

I could use a custom C++ launcher, but that would mean another language in the mix (on top of Python and QML) and another platform specific thing to maintain, so I would like to avoid that if possible.

Re: [Announce] modRana: a flexible GPS navigation system
 

I see, I didn't know about sailfish-qml. I have used qmlscene-qt5 on desktop before, but I assumed that Sailfish allowed only C++ launchers in harbour.

Is there any difference in performance? Some of my apps are pure QML (or QML+pyotherside), so I'd consider switching if it means better startup times.

Re: [Announce] modRana: a flexible GPS navigation system
 

I think there shoudn't be much of a difference in startup speed between a custom C++ launcher that uses libsailfishapp and using the sailfish-qml launcher. BTW, this should be the source code of the launcher:
