Public bug reported:
Snap package developers should be encouraged to store user data
according to the XDG Base Directory Specification [1][2].
I installed the "notes" app via snap on a Xenial desktop:
sudo snap install notes
and launched it using the snap wrapper script "/snap/bin/notes". The
script created a directory "$HOME/snap/notes/1", resulting in the
placement of the directory named "snap" directly under my home
directory, a situation that is undesirable for two reasons:
- The XDG spec calls for user data to be stored under
"$HOME/.local/share" (or rather, that's the specified default when the
environment variable XDG_DATA_HOME isn't explicitly set, and default
installations of Ubuntu don't appear to set it) .
- It clashes with the directory naming style on my desktop systems. All
directories located directly under $HOME that are not prefixed with a
dot are named using Capital Case -- e.g. "Desktop", "Documents",
"Pictures" -- a scheme which is consistent with the defaults defined in
"/etc/xdg/user-dirs.defaults" from package "xdg-user-dirs". A directory
under $HOME having an all-lowercase name introduces an ugly stylistic
inconsistency and it complicates the navigation of directories in the
shell when tab completion is case-sensitive.
Therefore snap packages should base the value of SNAP_USER_DATA on the
value of XDG_DATA_HOME (or its specified default). For the "notes" snap,
this would be "$HOME/.local/share/snap/notes/1".
If however the XDG spec is considered irrelevant to snap packages,
please consider using a proper UNIX-style dot-prefixed directory,
"$HOME/.snap".
