[QGIS-Developer] [Qgis-developer] OTB and LiDAR tools as separate plugins

[Martin Isenburg]

Hello,

my question was answered at the QGIS hackfest by Matteo Ghetta with a
DataPlotly code snippet. (-: You can add your own entries into the
"Processing Settings" menu under the "Providers" section by following the
example below in your own Provider class.

from processing.core.ProcessingConfig import Setting, ProcessingConfig

class LAStoolsProvider(QgsProcessingProvider):

    def __init__(self):
        QgsProcessingProvider.__init__(self)

    def load(self):
        ProcessingConfig.settingIcons[self.name()] = self.icon()
        ProcessingConfig.addSetting(Setting(self.name(),
'LASTOOLS_ACTIVATED', 'Activate', True))
        ProcessingConfig.addSetting(Setting(self.name(), 'LASTOOLS_FOLDER',
'LAStools folder', "C:\LAStools", valuetype=Setting.FOLDER))
        ProcessingConfig.addSetting(Setting(self.name(), 'WINE_FOLDER',
'Wine folder', "", valuetype=Setting.FOLDER))
        ProcessingConfig.readSettings()
        self.refreshAlgorithms()
        return True

    def unload(self):
        ProcessingConfig.removeSetting('LASTOOLS_ACTIVATED')
        ProcessingConfig.removeSetting('LASTOOLS_FOLDER')
        ProcessingConfig.removeSetting('WINE_FOLDER')
        pass

    def isActive(self):
        return ProcessingConfig.getSetting('LASTOOLS_ACTIVATED')

    def setActive(self, active):
        ProcessingConfig.setSettingValue('LASTOOLS_ACTIVATED', active)


    def loadAlgorithms(self):
       [...]

and you can always query those settings with code snippets such as

from processing.core.ProcessingConfig import ProcessingConfig
from processing.tools.system import isWindows

    @staticmethod
    def hasWine():
        wine_folder = ProcessingConfig.getSetting("WINE_FOLDER")
        return (wine_folder is not None) and (wine_folder != "")

    @staticmethod
    def LAStoolsPath():
        lastools_folder = ProcessingConfig.getSetting("LASTOOLS_FOLDER")
        if isWindows():
            wine_folder = ""
        else:
            wine_folder = ProcessingConfig.getSetting("WINE_FOLDER")
        if (wine_folder is None) or (wine_folder == ""):
            folder = lastools_folder
        else:
            folder = wine_folder + "/wine " + lastools_folder
        return folder

Regards,

Martin
