What is a portable way to store settings and generated app data for locally-run (desktop) python programs? Is there some pythonic right-way or a widely used 3rd party module?
Ideally I want some portable way to tie into OS X's defaults system and Windows' System.Configuration system. I'd settle for a way to get the right path to store persistent settings data for the user's OS.
I know about the various relevant technologies like sqlite/pickle/ConfigParser/json/shelve/dbm, but I haven't found a portable way to determine the right place for the user's OS and installation circumstances...
For example on Win XP/2000 it would probably be:
C:\Documents and Settings\<Windows login>\Application Data\<some app identifier>\
On Windows Vista and Windows 7 it would probably be:
C:\Users\<Windows login/user name>\AppData\Roaming\<some app identifier>\
On most Unix-like operating systems it would probably be:
~/.<some app identifier>/
On Mac OS X it would probably be:
~/Library/Application Support/<some app identifier>
I'm familiar with winpaths (from pypi), but it seems to be windows only. Do you just always use os.path to put a dot file in a users' home directory and hope for the best?
回答1:
There is an appdirs module on PyPi that should solve this in a portable way.
