"forward declare" functions which will be patched when the processing
plugin starts, so that these are known and accessible during the PyQGIS
doc building. Also make these forward declared versions raise
QgsNotSupportedException, so that its clear why they aren't working
when the processing plugin hasn't started
Fixes https://github.com/qgis/pyqgis-api-docs-builder/issues/38
The existing `alg.DATETIME` decorator only allows to define a
`QgsProcessingParameterDateTime` as a datetime.
This change allows to also define a `QgsProcessingParameterDateTime`
as a pure date or time by adding `alg.DATE` and `alg.TIME`.
* [cmake] generalize Python output directory in UseTest macro
this is helpful in case we set up another python output directory (eg PySide2)
* define python output directories to the parent scope
* try with target_include_directories
* define vars on top level
* Update UsePythonTest.cmake
* some cleanup
* more cleanup
* fix uic
* fix path for all platforms
* fix var
This adds a new available parameter type for processing algorithms,
QgsProcessingParameterAuthConfig, allowing selection from available
authentication configurations (and creation of new ones).
It allows creation of processing algorithm which can fully take
advantage of QGIS' mature authentication handling, avoiding the
need to use insecure string parameters for users to input
sensitive logon credentials.
QgsProcessingParameterAuthConfig parameters are evaluated using
QgsProcessingAlgorithm.parameterAsString(), which returns the
selected authentication configuration ID.
