the problem
|
|
===========
|
|
|
|
What directory should your app use for storing user data? If running on Mac OS X, you
|
|
should use::
|
|
|
|
~/Library/Application Support/<AppName>
|
|
|
|
If on Windows (at least English Win XP) that should be::
|
|
|
|
C:\Documents and Settings\<User>\Application Data\Local Settings\<AppAuthor>\<AppName>
|
|
|
|
or possibly::
|
|
|
|
C:\Documents and Settings\<User>\Application Data\<AppAuthor>\<AppName>
|
|
|
|
for `roaming profiles <http://bit.ly/9yl3b6>`_ but that is another story.
|
|
|
|
On Linux (and other Unices) the dir, according to the `XDG
|
|
spec <http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html>`_, is::
|
|
|
|
~/.local/share/<AppName>
|
|
|
|
|
|
``appdirs`` to the rescue
|
|
=========================
|
|
|
|
This kind of thing is what the ``appdirs`` module is for. ``appdirs`` will
|
|
help you choose an appropriate:
|
|
|
|
- user data dir (``user_data_dir``)
|
|
- user config dir (``user_config_dir``)
|
|
- user cache dir (``user_cache_dir``)
|
|
- site data dir (``site_data_dir``)
|
|
- site config dir (``site_config_dir``)
|
|
- user log dir (``user_log_dir``)
|
|
|
|
and also:
|
|
|
|
- is a single module so other Python packages can include their own private copy
|
|
- is slightly opinionated on the directory names used. Look for "OPINION" in
|
|
documentation and code for when an opinion is being applied.
|
|
|
|
|
|
some example output
|
|
===================
|
|
|
|
On Mac OS X::
|
|
|
|
>>> from appdirs import *
|
|
>>> appname = "SuperApp"
|
|
>>> appauthor = "Acme"
|
|
>>> user_data_dir(appname, appauthor)
|
|
'/Users/trentm/Library/Application Support/SuperApp'
|
|
>>> site_data_dir(appname, appauthor)
|
|
'/Library/Application Support/SuperApp'
|
|
>>> user_cache_dir(appname, appauthor)
|
|
'/Users/trentm/Library/Caches/SuperApp'
|
|
>>> user_log_dir(appname, appauthor)
|
|
'/Users/trentm/Library/Logs/SuperApp'
|
|
|
|
On Windows 7::
|
|
|
|
>>> from appdirs import *
|
|
>>> appname = "SuperApp"
|
|
>>> appauthor = "Acme"
|
|
>>> user_data_dir(appname, appauthor)
|
|
'C:\\Users\\trentm\\AppData\\Local\\Acme\\SuperApp'
|
|
>>> user_data_dir(appname, appauthor, roaming=True)
|
|
'C:\\Users\\trentm\\AppData\\Roaming\\Acme\\SuperApp'
|
|
>>> user_cache_dir(appname, appauthor)
|
|
'C:\\Users\\trentm\\AppData\\Local\\Acme\\SuperApp\\Cache'
|
|
>>> user_log_dir(appname, appauthor)
|
|
'C:\\Users\\trentm\\AppData\\Local\\Acme\\SuperApp\\Logs'
|
|
|
|
On Linux::
|
|
|
|
>>> from appdirs import *
|
|
>>> appname = "SuperApp"
|
|
>>> appauthor = "Acme"
|
|
>>> user_data_dir(appname, appauthor)
|
|
'/home/trentm/.local/share/SuperApp
|
|
>>> site_data_dir(appname, appauthor)
|
|
'/usr/local/share/SuperApp'
|
|
>>> site_data_dir(appname, appauthor, multipath=True)
|
|
'/usr/local/share/SuperApp:/usr/share/SuperApp'
|
|
>>> user_cache_dir(appname, appauthor)
|
|
'/home/trentm/.cache/SuperApp'
|
|
>>> user_log_dir(appname, appauthor)
|
|
'/home/trentm/.cache/SuperApp/log'
|
|
>>> user_config_dir(appname)
|
|
'/home/trentm/.config/SuperApp'
|
|
>>> site_config_dir(appname)
|
|
'/etc/xdg/SuperApp'
|
|
>>> os.environ['XDG_CONFIG_DIRS'] = '/etc:/usr/local/etc'
|
|
>>> site_config_dir(appname, multipath=True)
|
|
'/etc/SuperApp:/usr/local/etc/SuperApp'
|
|
|
|
|
|
``AppDirs`` for convenience
|
|
===========================
|
|
|
|
::
|
|
|
|
>>> from appdirs import AppDirs
|
|
>>> dirs = AppDirs("SuperApp", "Acme")
|
|
>>> dirs.user_data_dir
|
|
'/Users/trentm/Library/Application Support/SuperApp'
|
|
>>> dirs.site_data_dir
|
|
'/Library/Application Support/SuperApp'
|
|
>>> dirs.user_cache_dir
|
|
'/Users/trentm/Library/Caches/SuperApp'
|
|
>>> dirs.user_log_dir
|
|
'/Users/trentm/Library/Logs/SuperApp'
|
|
|
|
|
|
|
|
Per-version isolation
|
|
=====================
|
|
|
|
If you have multiple versions of your app in use that you want to be
|
|
able to run side-by-side, then you may want version-isolation for these
|
|
dirs::
|
|
|
|
>>> from appdirs import AppDirs
|
|
>>> dirs = AppDirs("SuperApp", "Acme", version="1.0")
|
|
>>> dirs.user_data_dir
|
|
'/Users/trentm/Library/Application Support/SuperApp/1.0'
|
|
>>> dirs.site_data_dir
|
|
'/Library/Application Support/SuperApp/1.0'
|
|
>>> dirs.user_cache_dir
|
|
'/Users/trentm/Library/Caches/SuperApp/1.0'
|
|
>>> dirs.user_log_dir
|
|
'/Users/trentm/Library/Logs/SuperApp/1.0'

|
|
|
|
appdirs 1.3.0
|
|
-------------
|
|
- [Unix, issue 16] Conform to XDG standard, instead of breaking it for
|
|
everybody
|
|
- [Unix] Removes gratuitous case mangling of the case, since \*nix-es are
|
|
usually case sensitive, so mangling is not wise
|
|
- [Unix] Fixes the utterly wrong behaviour in ``site_data_dir``, return result
|
|
based on XDG_DATA_DIRS and make room for respecting the standard which
|
|
specifies XDG_DATA_DIRS is a multiple-value variable
|
|
- [Issue 6] Add ``*_config_dir`` which are distinct on nix-es, according to
|
|
XDG specs; on Windows and Mac return the corresponding ``*_data_dir``
|
|
|
|
appdirs 1.2.0
|
|
-------------
|
|
|
|
- [Unix] Put ``user_log_dir`` under the *cache* dir on Unix. Seems to be more
|
|
typical.
|
|
- [issue 9] Make ``unicode`` work on py3k.
|
|
|
|
appdirs 1.1.0
|
|
-------------
|
|
|
|
- [issue 4] Add ``AppDirs.user_log_dir``.
|
|
- [Unix, issue 2, issue 7] appdirs now conforms to `XDG base directory spec
|
|
<http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html>`_.
|
|
- [Mac, issue 5] Fix ``site_data_dir()`` on Mac.
|
|
- [Mac] Drop use of 'Carbon' module in favour of hardcoded paths; supports
|
|
Python3 now.
|
|
- [Windows] Append "Cache" to ``user_cache_dir`` on Windows by default. Use
|
|
``opinion=False`` option to disable this.
|
|
- Add ``appdirs.AppDirs`` convenience class. Usage:
|
|
|
|
>>> dirs = AppDirs("SuperApp", "Acme", version="1.0")
|
|
>>> dirs.user_data_dir
|
|
'/Users/trentm/Library/Application Support/SuperApp/1.0'
|
|
|
|
- [Windows] Cherry-pick Komodo's change to downgrade paths to the Windows short
|
|
paths if there are high bit chars.
|
|
- [Linux] Change default ``user_cache_dir()`` on Linux to be singular, e.g.
|
|
"~/.superapp/cache".
|
|
- [Windows] Add ``roaming`` option to ``user_data_dir()`` (for use on Windows only)
|
|
and change the default ``user_data_dir`` behaviour to use a *non*-roaming
|
|
profile dir (``CSIDL_LOCAL_APPDATA`` instead of ``CSIDL_APPDATA``). Why? Because
|
|
a large roaming profile can cause login speed issues. The "only syncs on
|
|
logout" behaviour can cause surprises in appdata info.

appdirs 1.0.1 (never released)
|
|
------------------------------
|
|
|
|
Started this changelog 27 July 2010. Before that this module originated in the
|
|
`Komodo <http://www.activestate.com/komodo>`_ product as ``applib.py`` and then
|
|
as `applib/location.py
|
|
<http://github.com/ActiveState/applib/blob/master/applib/location.py>`_ (used by
|
|
`PyPM <http://code.activestate.com/pypm/>`_ in `ActivePython
|
|
<http://www.activestate.com/activepython>`_). This is basically a fork of
|
|
applib.py 1.0.1 and applib/location.py 1.0.1.
