Is it possible to use ParameterGrp from Python?

[furti]

Hi

Is it possible to use ParameterGrp from python to load a FreeCAD config File? I saw that there is a ParameterPy.cpp file (https://github.com/FreeCAD/FreeCAD/blob ... eterPy.cpp) that contains the parameter Group and a Import method. But i couldn't figure out how to use it via python.

I ask because I want to add the possibility to merge settings into existing presets for my macro https://github.com/furti/FreeCAD-PreferencesPresets

Thanks in advance

Best Regards
Daniel

are you looking for:

Code: Select all

pg = FreeCAD.ParamGet("User parameter:BaseApp/Preferences/Mod/Draft")
pg.GetString('constructiongroupname')

[wmayer]

Code: Select all

pg = FreeCAD.ParamGet("User parameter:BaseApp")
pg.Import(myparameterfile)

[furti]

pg = FreeCAD.ParamGet("User parameter:BaseApp/Preferences/Mod/Draft")

pg = FreeCAD.ParamGet("User parameter:BaseApp")

Thank you for your answers. But this is not exactly what I am searching for. I want to load e.g. a user.cfg file that is stored in a different location than the default user.cfg file and compare it to the parameters of the running FreeCAD instance. Then i can compare this two groups and show the user a diff. The user selects the parameters to merge and i save the group back into the other user.cfg file.

As it seems to me, your examples use the parameter groups of the running FreeCAD instance and a "Import" will override the settings of FreeCAD.

But after trying this I realized that the "getContents" method does no list the ParameterGroups inside a ParameterGroup. So it is not possible to list all parameters inside a group without knowing the parameter names beforehand.

Do you think such functionality will likely be available via Python in the future?

In C++ the class ParameterGrp has the methods GetGroups() and GetGroupName() so that we can expose a function to Python access this information.

That sounds great.
Do you think it is also possible to get access to the ParameterGrp constructor from python? As it seems it is not available in the Base module right now.

Thank you for your help.

What for?

What for?

Need a way to load different config files and compare them against each other for this macro i created https://forum.freecadweb.org/viewtopic.php?f=22&t=30795

Then the user can choose the settings to override and i can save the file back to the preset location without messing up the preferences of the current FreeCAD instance.

git commit 476a07ae2 exposes some more methods to Python.

Code: Select all

pg = FreeCAD.ParamGet("User parameter:BaseApp")
pg.GetGroups()
# returns ['Preferences', 'Macro', 'Workbench', 'MainWindow', 'History', 'Workbenches', 'LogLevels']
pg.GetGroup("Macro")

If you want to create a new group then simply write the name of the new group which will be created on-the-fly if it doesn't exist.

Code: Select all

pg.GetGroup("ThisCreatesANewGroup")
