[GRASS-dev] standardized options

[Margherita Di Leo]

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!
