Before, we always loaded the default session (if it existed) and then deleted
it. This was surprising as the default session was deleted even when another
session was loaded.
Now we don't delete it at all, and save the session to load in the state file.
See #523.
We already attempted this in c5a2039da4, but
having the directories as module attributes means they'll be created on start
(rather than when they're actually used), and it'd also be impossible to change
them after init for some reason in the future.
To still have a nice short API, we simply change the attributes to functions.
Closes#12.
See #499.
See #11.
This adds PyYAML as a new dependency.
It adds the following new commands:
:session-delete <name>
Delete a session.
:session-load <name>
Load a session.
:session-save [<name>]
Save a session.
:wq [<name>]
Save open pages and quit.
And the following new settings:
general -> save-session:
Whether to always save the open pages.
