- Linux: use whatever the xdg spec dictates
- Windows: use AppData(Roaming)
- OS X/Quarz: use NSApplicationSupportDirectory special directory, which
typically resolves to $HOME/Library/Application Support
If the preferred directory can't be used the code will fallback to
$HOME/.gnucash (the old location) if it exists. It won't create it
however. Instead if missing it will fall back to the platform's
temporary directory.
Code is added also to automatically migrate all data from the old
location to the new (only the first time).
It is split into
- /libgnucash (for the non-gui bits)
- /gnucash (for the gui)
- /common (misc source files used by both)
- /bindings (currently only holds python bindings)
This is the first step in restructuring the code. It will need much
more fine tuning later on.
