7.8 Controlling rules

Mew controls guess rules by two variables, ‘mew-refile-guess-control’ and ‘mew-refile-ctrl-multi’. If you want multiple candidates, set ‘mew-refile-ctrl-multi’ ‘t’. Otherwise, set it ‘nil’.

By default, ‘mew-refile-guess-control’ is declared as follows (since it is a declaration, ‘defvar’ is used):

(defvar mew-refile-guess-control
  '(mew-refile-guess-by-alist
    mew-refile-ctrl-throw
    mew-refile-guess-by-newsgroups
    mew-refile-guess-by-folder
    mew-refile-ctrl-throw
    mew-refile-ctrl-auto-boundary
    mew-refile-guess-by-thread
    mew-refile-ctrl-throw
    mew-refile-guess-by-from-folder
    mew-refile-ctrl-throw
    mew-refile-guess-by-from
    mew-refile-ctrl-throw
    mew-refile-guess-by-default))

Mew executes every function defined in ‘mew-refile-guess-control’ in order. Each function may guess multiple candidates.

Let's see the following example of ‘mew-refile-guess-control’ action.

‘mew-refile-guess-by-alist’

guessed +aaa and +bbb.

‘mew-refile-guess-by-folder’

guessed +ccc and +ddd.

‘mew-refile-guess-by-default’

guessed +eee.

If you want to provide all candidates, +aaa - +eee, set ‘mew-refile-ctrl-multi’ ‘t’. If you want to provide +aaa only, set it ‘nil’.

If you want +aaa - +ddd but do not want left candidates, in other words, you want +eee only when no candidate is guessed by functions executed before, set ‘mew-refile-ctrl-multi’ ‘t’ and insert ‘mew-refile-ctrl-throw’ between ‘mew-refile-guess-by-folder’ and ‘mew-refile-guess-by-default’.

‘C-uo’ displays the flow of guess rules in Message buffer.
