Hi,
I am using QGIS 1.8.0 in Mac OS Lion. I have installed the Openlayers plugin
and made a map I am happy with. But now I have to make about a dozen similar
maps so I'd like to automate the process. I am used to writing Python scripts,
but am new to pyqgis.
I have added /Volumes/Macintosh\
HD/Applications/QGIS.app/Contents/Resources/python to my PYTHONPATH, and set
LD_LIBRARY_PATH to /Volumes/Macintosh\
HD/Applications/QGIS.app/Contents/MacOS/lib. So I can now import qgis.core and
qgis.utils with no problem. But I can't seem to access any plugins. E.g.
In [70]: qgis.utils.loadPlugin('openlayers')
Out[70]: False
and:
In [71]: qgis.utils.plugins
Out[71]: {}
The open layers plugin is installed in ~/.qgis/python/plugins, and other
plugins appear to be in /Volumes/Macintosh\
HD/Applications/QGIS.app/Contents/PlugIns.
There appears to be a qgis.utils.plugin_paths, and a
qgis.utils.pluginDirectory, as well as things like findPlugins() and
loadPlugin(). Can anyone please tell me if these are what I need to use, and if
so does anyone know the correct calling sequence to get my plugin loaded
properly?
Also, I have seen that pyqgis scripts should use QgsApplication.setPrefixPath
to set the QGIS 'installation directory', and then call
QgsApplication.initQgis(). But what is the 'installation directory': QGIS.app,
QGIS.app/Contents, QGIS.app/Contents/MacOS? Perhaps someone could please tell
me what subdirectories the installation directory should contain?
Many thanks,
- Phil
