Wicked Cool Emacs: BBDB: Use nicknames and custom salutations

Posted: - Modified: | bbdb, emacs, wickedcoolemacs

Update 2014-05-13: The original code is for BBDB version 2. Thomas Morgan sent this update which makes it work with BBDB version 3 – see below.

I like starting my e-mail with a short salutation such as “Hello, Mike!”, “Hello, Michael”, or “Hello, Mikong!”, but it can be hard to remember which nicknames people prefer to use, and calling someone by the wrong name is a bit of a faux pas. Sometimes people sign e-mail with their preferred name, but what if you haven’t sent e-mail to or received e-mail from someone in a while? In this project, you’ll learn how to set up my BBDB to remember people’s nicknames for you using a custom “nick” field, and to use those nicknames when replying to messages in Gnus or composing messages from my BBDB.

The nickname code worked so well that I started thinking of what else I could customize. It was easy to go from nicknames to personalized salutations. This hack started because one of my friends is from Romania, so I thought I’d greet her in Romanian with “Salut, Letitia!” instead of just “Hello, Letitia!”. The code in this project uses a “hello” field to store these salutations in your BBDB.

To set up personalized nicknames and salutations, add the following code to your ~/.emacs:

After you add this code, you can store personalized nicknames and salutations in your BBDB. Nicknames and salutations will be looked up using people’s e-mail addresses. While in the *BBDB* buffer, you can type C-o (bbdb-insert-new-field) to add a field to the current record. Add a nick field with the person’s nickname, or a hello field with a custom salutation. When you compose a message to or reply to a message from that person, the salutation or nickname will be included. If no nickname can be found, the recipient’s name will be used instead.

A number of variables can be used to modify the behavior of this code(1). For example, you may or may not want to greet 20 people individually. The default value of wicked/gnus-nick-threshold is to greet up to four people individually, and greet more people collectively. If you always want to greet people individually, add (setq wicked/gnus-nick-threshold nil) to your ~/.emacs. If you want to change the strings used to greet people individually or collectively, change wicked/bbdb-hello-string and wicked/bbdb-hello-all-string. If you want to store the data into different fields, change wicked/bbdb-nick-field and wicked/bbdb-salutation-field, but note that old data will not be automatically copied to the new fields.

Here’s how the code works. First, it retrieves the list of addresses from the header(2). If there are more addresses than wicked/gnus-nick-threshold, then wicked/bbdb-hello-all-string is used to greet everyone. If not, each recipient address is looked up. If the recipient cannot be found in your BBDB, then the recipient’s name or e-mail address is used(4). If there is a personalized salutation, it is used(5). If there is a nickname, it is used(6). If the person has a record but neither salutation or nickname, then the name of the record is used(7). After all recipients have been processed, the names are added to the message(8), followed by the salutations(9). This function is added to the different Gnus message-posting functions, so it should be called whenever you compose or reply to messages.

BBDB: Filtering by Mail Alias

| bbdb, emacs, wickedcoolemacs

You can use “a” (bbdb-add-or-remove-mail-alias) in BBDB buffers to add a mail alias to the current entry, or “* a” to add a mail alias to all displayed entries. I use mail aliases to tag or categorize my contacts (example: emacs, writing, etc.). The following functions can make it easy for you to filter displayed records using a combination of keywords:

Display records matching ALIAS and ALIAS M-x sacha/bbdb-filter-displayed-records-by-alias RET alias alias
Display records matching ALIAS or ALIAS C-u M-x sacha/bbdb-filter-displayed-records-by-alias RET alias alias
Omit records matching ALIAS and ALIAS M-x sacha/bbdb-omit-displayed-records-by-alias RET alias alias
Omit records matching ALIAS or ALIAS C-u M-x sacha/bbdb-omit-displayed-records-by-alias RET alias alias

Here’s the code:

(defun sacha/bbdb-filter-by-alias-match-all (query-aliases record-aliases)
  "Return non-nil if all QUERY-ALIASES are in RECORD-ALIASES."
  (let ((result t))
    (while query-aliases
      (unless (member (car query-aliases) record-aliases)
        (setq query-aliases nil
              result nil))
      (setq query-aliases (cdr query-aliases)))
    result))

(defun sacha/bbdb-filter-by-alias-match-any (query-aliases record-aliases)
  "Return non-nil if any in QUERY-ALIASES can be found in RECORD-ALIASES."
  (let (result)
    (while query-aliases
      (when (member (car query-aliases) record-aliases)
        (setq query-aliases nil
              result t))
      (setq query-aliases (cdr query-aliases)))

BBDB: Show a phone list

| bbdb, emacs, wickedcoolemacs

When I find myself in an airport, I sometimes take a little time to say hi to a bunch of people who are suddenly just a local call a way. Or sometimes I’m thinking of going somewhere, and instead of flipping through my phone’s address book, I’ll check my computer to see who might be interested.

You can use this function to filter phone numbers in your BBDB based on a regular expression. As usual, leaving the regular expression blank means that all records with phone numbers will be displayed. By default, the function works on the currently displayed records, allowing you to apply multiple filters. You can call it with a universal prefix argument (C-u M-x sacha/bbdb-find-people-with-phones) to match against all contacts in your database.

Here’s the code:

(defun sacha/bbdb-find-people-with-phones (&optional regexp records)
  "Search for phone numbers that match REGEXP in BBDB RECORDS.
Without a prefix argument, filter the list of displayed records.
Call with a prefix argument to search the entire database.  This
works best if you use a consistent format to store your phone
numbers.  The search will strip out non-numeric characters. For
example, +1-888-123-4567 will be treated as +18001234567.

To search for all numbers in Toronto, search for
\"+1\\(416\\|647\\)\". If you search for certain areas
frequently, it might be a good idea to define a function for
them."

Contact report

Posted: - Modified: | bbdb, emacs, planner

I started tracking e-mail sent on 2006.09.01 with a
nifty piece of Emacs Lisp code I wrote just for the
purpose. Now I have two months of interesting data which include not
only e-mail but also the occasional in-person contact or phone call
that I remember to note. It’s not complete – e-mail’s the only thing
that gets automatically tracked – but it does give me interesting
information. Here’s the contact report for your amusement:

Contact report

It’s sorted by overall frequency and then by regular frequency.
Warning! Parentheses follow.

Crazy Emacs: Personalized signatures with random taglines

| bbdb, emacs

Of course, that naturally leads to the crazy idea: “What if I can
personalize my signatures?” Knowing that Paul Lussier is an Emacs geek, I can reward him for reading all the way
to the bottom of my message… ;)

(defun sacha/gnus-personalize-signature ()
  "Personalizes signature based on BBDB signature field.
BBDB signature field should be a lambda expression.
First person with a custom signature field gets used."
  (let* ((bbdb-get-addresses-headers
          (list (assoc 'recipients bbdb-get-addresses-headers)))
         (records (bbdb-update-records
                   (bbdb-get-addresses
                    nil
                    gnus-ignored-from-addresses 'gnus-fetch-field)
                   nil
                   nil))
         signature)
    (while (and records (not signature))
      (when (bbdb-record-getprop (car records) 'signature)
        (setq signature
              (eval (read (bbdb-record-getprop (car records)
                                               'signature)))))
      (setq records (cdr records)))
    (or signature t)))
(setq-default message-signature 'sacha/gnus-personalize-signature)

So then all I have to do is add the following field to his record:

      signature: (concat "Sacha Chua - Emacs geek
                 What crazy idea can I help you hack next?
                 Random Emacs symbol: "
                 (sacha/random-tagline
                  "~/.taglines.random-emacs-symbols"))

Emacs. One crazy idea at a time. Now I can use this to select random
information, like my favorite networking books or a list of my
upcoming events…

Random Emacs symbol: sort-coding-systems-predicate – Variable: If non-nil, a predicate function to sort coding systems.

Emacs BBDB: Prioritize exact matches

| bbdb, emacs

I often include people’s names in my notes on other people, such as
when I’m tracking who introduced me to whom. The following code
modifies BBDB’s behavior to put exact matches for name, company, or
network address above matches for notes.

(defun sacha/bbdb (string elidep)
  "Display all entries in the BBDB matching the regexp STRING
in either the name(s), company, network address, or notes.
Prioritize non-note matches."
  (interactive
   (list (bbdb-search-prompt "Search records %m regexp: ")
         current-prefix-arg))
  (let* ((bbdb-display-layout (bbdb-grovel-elide-arg elidep))
         (notes (cons '* string))
         (records-top
          (bbdb-search (bbdb-records) string string string nil
                       nil))
         (records
          (bbdb-search (bbdb-records) string string string notes
                       nil))
         temp)
    (setq temp records-top)
    (while temp
      (setq records (delete (car temp) records))
      (setq temp (cdr temp)))
    (if (or records-top records)
        (bbdb-display-records (append
                               records-top
                               records))
      ;; we could use error here, but it's not really an error.
      (message "No records matching '%s'" string))))
