Single-window mode is meant to minimize mu4e window operations (opening,
killing, resizing, etc) and buffer changes, while still retaining the
view and headers buffers. In addition, it replaces mu4e main view with a
minibuffer prompt containing the same information.
As discussed in issue #751, mu4e should tried to accommodate some
different ways of choosing the context.
We add a new policy `ask-if-none', that will only query the user if
there is no context yet; this is the new default for
mu4e-context-policy, i.e. what happens when entering the main view.
The default policy for mu4e-compose-context-policy is now `ask',
i.e. ask if none of the contexts match.
The idea is for the defaults to ask when we don't know a context, and we
can't determine one using the match functions; this is probably the
least confusing. When user gets annoyed by too many question, they can
tweak the behavior to their liking. I.e. 'ask questions first, shoot
later'
Document all of this.
When we determine the drafts/refile/trash/sent folder, see if we can
find a context matching the particular message. If we find one, let-bind
the vars for that context before determining the folder.
This allows e.g for moving message to context-specific folder, rather
than the one for the current context - useful when dealing with headers
buffers with message belonging to different contexts.
Allow setting a policy about what context to choose when starting mu4e
and composing a message. Basically:
When you have defined contexts and you start mu4e it decides which
context to use based on the variable `mu4e-context-policy';
similarly, when you compose a new message, the context is determined
using `mu4e-compose-context-policy'.
These policies can be one of the following:
- a symbol always-ask: unconditionally ask the user what context to pick
The other choices only apply if none of the context matches (i.e., if
none of the contexts' match-functions returns t:
- symbol ask: ask the user
- a symbol pick-first: pick the first context
- nil: don't change the context
Update mu4e-context-switch to not call the enter/leave functions when
'changing' to the current context. However, calling those functions (if
defined) can be force through a prefix arg. Document this.
Make mu4e-context-determine recognize 'policies', i.e. what to do when
no context matches. This part is WIP.
When contexts have been defined, automatically select one at startup --
either the first whose match-function returns non-nil, or simply the
first one.
Document this, too.
Define mu4e-context - a structure with settings and enter/leave
functions for contexts, and some functions for switching between
contexts and auto-detecting them.
