"appname" is the name of application.
|
|
If None, just the system directory is returned.
|
|
"appauthor" (only used on Windows) is the name of the
|
|
appauthor or distributing body for this application. Typically
|
|
it is the owning company name. This falls back to appname. You may
|
|
pass False to disable it.
|
|
"version" is an optional version path element to append to the
|
|
path. You might want to use this if you want multiple versions
|
|
of your app to be able to run independently. If used, this
|
|
would typically be "<major>.<minor>".
|
|
Only applied when appname is present.
|
|
"opinion" (boolean) can be False to disable the appending of
|
|
"Cache" to the base app data dir for Windows. See
|
|
discussion below.
|
|
|
|
Typical user cache directories are:
|
|
Mac OS X: ~/Library/Caches/<AppName>
|
|
Unix: ~/.cache/<AppName> (XDG default)
|
|
Win XP: C:\Documents and Settings\<username>\Local Settings\Application Data\<AppAuthor>\<AppName>\Cache
|
|
Vista: C:\Users\<username>\AppData\Local\<AppAuthor>\<AppName>\Cache
|
|
|
|
On Windows the only suggestion in the MSDN docs is that local settings go in
|
|
the `CSIDL_LOCAL_APPDATA` directory. This is identical to the non-roaming
|
|
app data dir (the default returned by `user_data_dir` above). Apps typically
|
|
put cache data somewhere *under* the given dir here. Some examples:
|
|
...\Mozilla\Firefox\Profiles\<ProfileName>\Cache
|
|
...\Acme\SuperApp\Cache\1.0
|
|
OPINION: This function appends "Cache" to the `CSIDL_LOCAL_APPDATA` value.
|
|
This can be disabled with the `opinion=False` option.
