I've just edebugged Juliens function, and if I try to complete
To: Stefan Monnier <monn...@iro.umontreal.ca>, a<tab>
in this message buffer, his function returns
(376 377 (#("Andreas XXX <xxx@xxx.invalid>" 0 12 (org-category "contacts"
fontified nil))))
which is correct. Case didn't get accounted, and that's the only
possible completion. However, what gets inserted after the "a" is only
a TAB character.
The value of `completion-styles' in the current message buffer is
(basic initials partial-completion),
which should be ok for that kind of completion.
But the global value of completion-ignore-case is nil. So the problem
seems to be that Julien's completion at point functions respects the
value of his own `org-contacts-completion-ignore-case' variable when
*calculating* completions, but it is not considered anymore when the
completion style *applies* the completions.
When I do
(set (make-local-variable 'completion-ignore-case) t)
in the current message buffer and try again, then "a<tab>" is correctly
completed to the Andreas Julien's function calculated. However, I want
case insensitive completion only for contact completion in the headers,
but not in the message body.
So the question is: how can the completion-ignore-case value be
propagated from the completion gathering function in
`completion-at-point-functions' to the function that actually applies
this completion, without having to modify the global or buffer local
value of `completion-ignore-case'?
Bye,
Tassilo
