Dear Devs,
in r57084 Martin has added standardized options to r.ipso (thanks!). I would like to learn more about their use, particularly, does it exist a standard variable defined for taking a path as input? (Not a path+file name as G_OPT_F_INPUT). For example this is useful in the case that a module produces some pictures and/or csv files and the user wants to set a folder for storing them. I digged into [1] but I seem not to find what I need. Should I just take the path as a string? Giving to the user the possibility to browse the folders instead of indicating a path would be IMHO more convenient. Could anyone point me out where to read in order to learn more about that?
Thanks!

You could try G_OPT_M_DIR. The comment says "directory input" but it
should also work for output, all it should return is the path to a
folder.

Hi Madi,
that’s interesting and there is even a G_OPT_R_ELEV, I was not aware of it.
You can have a look into these:
