Pure Maps is an application for Sailfish OS and Linux to display vector and raster maps, places, routes, and provide navigation instructions with a flexible selection of data and service providers.
Pure Maps is free software released under the GNU General Public
License (GPL), see the file COPYING
for details. Pure
Maps is a fork of WhoGo Maps
that was made to continue its development.
To support multiple platforms, QML code is split into
platform-specific and platform-independent parts. Platform-independent
part is in qml
folder with the platform-dependent code under
qml/<platform-id>
. To switch between platforms, one has to make a
symbolic link from the corresponding qml/<platform-id>
to
qml/platform
. This can be done by running
make platform-qtcontrols
for example. Current platforms are
- platform.kirigami -> make target
platform-kirigami
- platform.qtcontrols -> make target
platform-qtcontrols
- platform.silica -> make target
platform-silica
Within platform-independent code, platform is included allowing to access platform-specific implementations of page stack, file dialog, and other specific aspects. For this approach to work, API in the platform specific implementation has to be the same for all platforms.
To add new platform, add new directory under qml
, new Makefile
target to set it, and implement all the required QML items. Take a
look under other platforms for examples.
For testing purposes you can just run qmlscene qml/pure-maps.qml
,
after setting the platform.
In addition to common dependencies for QML applications, the following are needed:
- Nemo DBus https://git.merproject.org/mer-core/nemo-qml-plugin-dbus
- PyOtherSide https://github.com/thp/pyotherside
- PyXDG https://www.freedesktop.org/wiki/Software/pyxdg/
- Mapbox GL Native, Qt version, use the packaged version at https://github.com/rinigus/pkg-mapbox-gl-native
- Mapbox GL QML, unofficial QML bindings, https://github.com/rinigus/mapbox-gl-qml
- [flatpak only] QML runner https://github.com/rinigus/qmlrunner
When developing with Kirigami using flatpak builder, dependencies will be pulled and installed in flatpak. See instructions regarding Kirigami below.
At present, Sailfish OS version is packaged as RPM and Linux version is packaged using Flatpak.
For packaging, please copy tools/apikeys_dummy.py
to
tools/apikeys.py
and fill missing API keys for the services that you
plan to use.
For installation on Sailfish, you can build the RPM package with
command make rpm
. You don't need an SDK to build the RPM, only basic
tools: make
, rpmbuild
, gettext
and qttools
.
Flatpak specific instructions are available under packaging/flatpak
.
There are two main communication channels with the users: Github and a thread at TMO.
Please use Github issues to address specific problems and development requests. General discussion is expected either through corresponding issues opened by maintainer or TMO thread. Please note that users from all platforms are welcome at TMO, not only current Sailfish OS users.
Kirigami platform may require latest platform SDK available as flatpaks. See instructions at https://docs.plasma-mobile.org/AppDevelopment.html for local development. From these instructions, only SDK install is needed. After that, building and running can be performed by
make flatpak-build flatpak-run
If you wish to install development version for testing, you could use the following command instead (will build the package, bundle it, uninstall current version of Pure Maps, and install the freshly built one):
make flatpak-dev-install
Throughout QML and Python code, all the same type items (properties, signals, functions), are ordered alphabetically.
Its possible that some of the implemented code does not fully comply with the outlined order. Then it should be fixed eventually.
To simplify development, there are few simple rules regarding QML file organization. QML files are organized as follows (use the needed components):
import A
import B
import "."
import "js/util.js" as Util
Item {
id: item
// base class defined properties in alphabetic order
prop_a: val_a
prop_b: val_b
// new properties in alphabetic order
property var np_a: default_a
default property bool np_b: default_b
// readonly properties
readonly property var images: QtObject {
readonly property string pixel: "pure-image-pixel"
readonly property string poi: "pure-image-poi"
readonly property string poiBookmarked: "pure-image-poi-bookmarked"
}
// signals
signal mySignal
// local unexported properties
property bool _locked: false
// behavior
Behavior on bearing {
RotationAnimation {
direction: RotationAnimation.Shortest
duration: map.ready ? 500 : 0
easing.type: Easing.Linear
}
}
// new sub-items following the same principles
Item {
id: subitem
}
// connections
Connections {
}
// signal handlers
Component.onCompleted: init()
onActivated: doSomething()
// functions
function a() {
return 10;
}
}
