Name washing

Name washing

[Paul Stevenson]

Has anyone written, or does gnus already have some function to wash
names?

I have in mind turning things like
Lars Magne Ingebrigtsen <larsi@gnus.org>
which one gets as %n in gnus-summary-line-format into a shorter form
such as
L M Ingebrigtsen
so that people's full names can appear without making the field too
wide.

Obviously I would be after some clever function which could turn
wmperry@aventail.com (William M. Perry)
into W M Perry
or similar.

I just thought I'd see if any bits of code existed before I
re-implement it...

okay, it was easier than I thought for just a very simple heuristic
algorithm:


(defun ps-wash-name (name)
  (if (stringp name)
      (if (string= name (car (split-string name "(")))
	  (progn
	    (if (string= name (car (split-string name "<")))
		(car (split-string name "@"))
	      (car (split-string name " <"))))
	(car (cdr (split-string name "(\\|)"))))
    "Fudged name"))

then with 

(defun gnus-user-format-function-a (headers)
  (let ((name (aref headers 2)))
    (ps-wash-name name)))

I can have 

(setq gnus-summary-line-format "%U%R%z%I%(%[%4L: %-20,20ua%]%) %s\n")

and it does most of what I want. woo-hoo. Hooray for
gnus-user-format-function

doh!

I had my format line previously set to something weird, so I had
thought that the default was not to remove the email address. All I've
done is reproduced the default behaviour.
Sorry 'bout the wasted bandwidth.

It probably wasn't a waste of time, after all, since getting the plain
name sans email address as a string means that I can do the extra
length reduction (turning first names into initials) as I had outlined
in the first mail.

This vector is a data structure used internally by Gnus, and there are
a number of accessor functions for it.  mail-header-from might be what
you are looking for.

I have the following, to use the full names out of the BBDB, prefixed
with '*' (or a marker char from their notes).  It works with the "To:"
hack if you get nnmail to re-write NOV entries for your own sent mail.

(defun bbdb-extract-address-components (from)
  "Get the real name of FROM from the BBDB.\n
Meant for use as the value of gnus-extract-address-components."
  (if (string-match "^=> " from)
      (let ((components (bbdb-extract-address-components (substring from 3))))
        (cons (concat "=>" (car components))
              (cdr components)))
    (let* ((mail-extr-ignore-single-names t)
           (data (condition-case ()
                     (mail-extract-address-components from)
                   (error nil)))
           (name (car data))
           (net (car (cdr data)))
           (net-canon (if (and net bbdb-canonicalize-net-hook)
                          (bbdb-canonicalize-address net)
                        net))
           (record (and data (bbdb-search-simple name net-canon)))
           string L)

      (if (and record name (member (downcase name) (bbdb-record-net record)))
          ;; bogon!
          (setq record nil))

      (setq name (or (and bbdb/gnus-header-prefer-real-names
                          (or (and bbdb/gnus-header-show-bbdb-names record
                                   (bbdb-record-name record))
                              name
                              (car (gnus-extract-address-components from))))
                     net))
      (list (format "%s%s"
                    (if (and record bbdb/gnus-mark-known-posters)
                        (or (bbdb-record-getprop record bbdb-message-marker-field) "*")
                      " ")
                    (or name from))
            net))))

(setq gnus-extract-address-components 'bbdb-extract-address-components)
