gnus: Article Hiding

 
 3.18.3 Article Hiding
 ---------------------
 
 Or rather, hiding certain things in each article.  There usually is much
 too much cruft in most articles.
 
 ‘W W a’
      Do quite a lot of hiding on the article buffer
      (‘gnus-article-hide’).  In particular, this function will hide
      headers, PGP, cited text and the signature.
 
 ‘W W h’
      Hide headers (‘gnus-article-hide-headers’).  Hiding
      Headers.
 
 ‘W W b’
      Hide headers that aren’t particularly interesting
      (‘gnus-article-hide-boring-headers’).  Hiding Headers.
 
 ‘W W s’
      Hide signature (‘gnus-article-hide-signature’).  Article
      Signature.
 
 ‘W W l’
      Strip list identifiers specified in ‘gnus-list-identifiers’.  These
      are strings some mailing list servers add to the beginning of all
      ‘Subject’ headers—for example, ‘[zebra 4711]’.  Any leading ‘Re: ’
      is skipped before stripping.  ‘gnus-list-identifiers’ may not
      contain ‘\\(..\\)’.
 
      ‘gnus-list-identifiers’
           A regular expression that matches list identifiers to be
           removed from subject.  This can also be a list of regular
           expressions.
 
 ‘W W P’
      Hide PEM (privacy enhanced messages) cruft
      (‘gnus-article-hide-pem’).
 
 ‘W W B’
      Strip the banner specified by the ‘banner’ group parameter
      (‘gnus-article-strip-banner’).  This is mainly used to hide those
      annoying banners and/or signatures that some mailing lists and
      moderated groups adds to all the messages.  The way to use this
      function is to add the ‘banner’ group parameter (Group
      Parameters) to the group you want banners stripped from.  The
      parameter either be a string, which will be interpreted as a
      regular expression matching text to be removed, or the symbol
      ‘signature’, meaning that the (last) signature should be removed,
      or other symbol, meaning that the corresponding regular expression
      in ‘gnus-article-banner-alist’ is used.
 
      For instance:
 
           (setq gnus-article-banner-alist
                 ((googleGroups .
                  "^\n*--~--~---------\\(.+\n\\)+")))
 
      Regardless of a group, you can hide things like advertisements only
      when the sender of an article has a certain mail address specified
      in ‘gnus-article-address-banner-alist’.
 
      ‘gnus-article-address-banner-alist’
           Alist of mail addresses and banners.  Each element has the
           form ‘(ADDRESS . BANNER)’, where ADDRESS is a regexp matching
           a mail address in the From header, BANNER is one of a symbol
           ‘signature’, an item in ‘gnus-article-banner-alist’, a regexp
           and ‘nil’.  If ADDRESS matches author’s mail address, it will
           remove things like advertisements.  For example, if a sender
           has the mail address ‘hail@yoo-hoo.co.jp’ and there is a
           banner something like ‘Do You Yoo-hoo!?’ in all articles he
           sends, you can use the following element to remove them:
 
                ("@yoo-hoo\\.co\\.jp\\'" .
                 "\n_+\nDo You Yoo-hoo!\\?\n.*\n.*\n")
 
 ‘W W c’
      Hide citation (‘gnus-article-hide-citation’).  Some variables for
      customizing the hiding:
 
      ‘gnus-cited-opened-text-button-line-format’
      ‘gnus-cited-closed-text-button-line-format’
           Gnus adds buttons to show where the cited text has been
           hidden, and to allow toggle hiding the text.  The format of
           the variable is specified by these format-like variable (
           Formatting Variables).  These specs are valid:
 
           ‘b’
                Starting point of the hidden text.
           ‘e’
                Ending point of the hidden text.
           ‘l’
                Number of characters in the hidden region.
           ‘n’
                Number of lines of hidden text.
 
      ‘gnus-cited-lines-visible’
           The number of lines at the beginning of the cited text to
           leave shown.  This can also be a cons cell with the number of
           lines at the top and bottom of the text, respectively, to
           remain visible.
 
 ‘W W C-c’
 
      Hide citation (‘gnus-article-hide-citation-maybe’) depending on the
      following two variables:
 
      ‘gnus-cite-hide-percentage’
           If the cited text is of a bigger percentage than this variable
           (default 50), hide the cited text.
 
      ‘gnus-cite-hide-absolute’
           The cited text must have at least this length (default 10)
           before it is hidden.
 
 ‘W W C’
      Hide cited text in articles that aren’t roots
      (‘gnus-article-hide-citation-in-followups’).  This isn’t very
      useful as an interactive command, but might be a handy function to
      stick have happen automatically (Customizing Articles).
 
    All these “hiding” commands are toggles, but if you give a negative
 prefix to these commands, they will show what they have previously
 hidden.  If you give a positive prefix, they will always hide.

 customization.
