- the local deck name must now match the online deck - syncName is a hash of the current deck's path or None - the hash is checked on deck load, and if it is different (because the deck was copied or moved), syncing is disabled. This should prevent people from accidentally clobbering their online decks

Hooks - hook management and tools for extending Anki
|
|
==============================================================================
|
|
|
|
To find available hooks, grep for runHook in the source code.
|
|
|
|
Instrumenting allows you to modify functions that don't have hooks available.
|
|
If you call wrap() with pos='around', the original function will not be called
|
|
automatically but can be called with _old().
