• Things to do elsewhere

  • TODO QgsProcessingParameterPoint can't be used anymore.
  • TODO We need NULL QgsProcessingParameterPoint!
  • TODO We need a QgsParameterMultipleInputLayers parameter for minimum and maximum number of layers.
  • TODO Open all the files in a QgsProcessingOutputFolder at the end of the algorithm.

• TODO Review all the methods of QgsProcessingAlgorithm.

• DONE Improve Grass Path and Binary detection for all OSs.

• DONE Replace all parameters by QgsProcessingParameters.

  • DONE Support multiple QgsProcessingParameterEnum.
  • DONE Review all ParameterFile
  • DONE Review all OutputDirectory.
    • DONE Convert all OutputDirectory to QgsProcessingParameterFolderDestination
    • DONE Default case:
      • Take the name of the output variable.
      • create a default value as basename.
      • export all layers into the directory with a shell loop.
    • DONE Remove all multipleOutputDir in ext/
