gnus: Home Score File

 
 7.7 Home Score File
 ===================
 
 The score file where new score file entries will go is called the “home
 score file”.  This is normally (and by default) the score file for the
 group itself.  For instance, the home score file for ‘gnu.emacs.gnus’ is
 ‘gnu.emacs.gnus.SCORE’.
 
    However, this may not be what you want.  It is often convenient to
 share a common home score file among many groups—all ‘emacs’ groups
 could perhaps use the same home score file.
 
    The variable that controls this is ‘gnus-home-score-file’.  It can
 be:
 
   1. A string.  Then this file will be used as the home score file for
      all groups.
 
   2. A function.  The result of this function will be used as the home
      score file.  The function will be called with the name of the group
      as the parameter.
 
   3. A list.  The elements in this list can be:
 
        1. ‘(REGEXP FILE-NAME)’.  If the REGEXP matches the group name,
           the FILE-NAME will be used as the home score file.
 
        2. A function.  If the function returns non-‘nil’, the result
           will be used as the home score file.  The function will be
           called with the name of the group as the parameter.
 
        3. A string.  Use the string as the home score file.
 
      The list will be traversed from the beginning towards the end
      looking for matches.
 
    So, if you want to use just a single score file, you could say:
 
      (setq gnus-home-score-file
            "my-total-score-file.SCORE")
 
    If you want to use ‘gnu.SCORE’ for all ‘gnu’ groups and ‘rec.SCORE’
 for all ‘rec’ groups (and so on), you can say:
 
      (setq gnus-home-score-file
            'gnus-hierarchial-home-score-file)
 
    This is a ready-made function provided for your convenience.  Other
 functions include
 
 ‘gnus-current-home-score-file’
      Return the “current” regular score file.  This will make scoring
      commands add entry to the “innermost” matching score file.
 
    If you want to have one score file for the ‘emacs’ groups and another
 for the ‘comp’ groups, while letting all other groups use their own home
 score files:
 
      (setq gnus-home-score-file
            ;; All groups that match the regexp ‘"\\.emacs"’
            '(("\\.emacs" "emacs.SCORE")
              ;; All the comp groups in one score file
              ("^comp" "comp.SCORE")))
 
    ‘gnus-home-adapt-file’ works exactly the same way as
 ‘gnus-home-score-file’, but says what the home adaptive score file is
 instead.  All new adaptive file entries will go into the file specified
 by this variable, and the same syntax is allowed.
 
    In addition to using ‘gnus-home-score-file’ and
 Parameters::) and topic parameters (SeeTopic Parameters) to achieve
 much the same.  Group and topic parameters take precedence over this
 variable.
