118 @section LDAP
119
120 LDAP, @dfn{the Lightweight Directory Access Protocol}, is a communication
121 protocol for directory applications defined in RFC 1777.
122
123 Quoted from RFC 1777:
124
125 @quotation
126 [LDAP] is designed to provide access to the X.500 Directory while not
127 incurring the resource requirements of the Directory Access Protocol
128 (DAP). This protocol is specifically targeted at simple management
129 applications and browser applications that provide simple read/write
130 interactive access to the X.500 Directory, and is intended to be a
131 complement to the DAP itself.
132 @end quotation
133
134 LDAP servers usually store (but are not limited to) information about
135 people such as their name, phone number, email address, office
136 location, etc@enddots{} More information about LDAP can be found at
137 @url{http://www.openldap.org/}.
138
139 EUDC requires external support to access LDAP directory servers
140 (@pxref{LDAP Requirements})
141
142
143 @node CCSO PH/QI
144 @section CCSO PH/QI
145
146 The Central Computing Services Office (CCSO) of the University of
147 Illinois at Urbana Champaign created and freely distributed a
148 directory system that was used by many organizations in the 1990s.
149 The system records information about people such as their address,
150 phone number, email, academic information or any other details it was
151 configured to. Nowadays this system is not widely used.
152
153 The system consists of two parts: a database server traditionally called
154 @samp{qi} and a command-line client called @samp{ph}.
155 @ignore
156 Until 2010, the code could be downloaded from
157 @url{http://www-dev.cites.uiuc.edu/ph/}.
158 @end ignore
159
160 The original command-line @samp{ph} client that came with the
161 @samp{ph/qi} distribution provided additional features that are
162 not implemented in EUDC, like the possibility to communicate with the
163 server in login-mode, which made it possible to change records in the
164 database.
165
166
167 @node BBDB
168 @section BBDB
169
170 BBDB is the @dfn{Big Brother's Insidious Database}, a package for Emacs
171 originally written by Jamie Zawinski which provides rolodex-like
172 database functionality featuring tight integration with the Emacs mail
173 and news readers.
174
175 It is often used as an enhanced email address book.
176
177 EUDC considers BBDB as a directory server back end just like LDAP or
178 PH/QI servers, though BBDB has no client/server protocol and thus always
179 resides locally on your machine. The point in this is not to offer an
180 alternate way to query your BBDB database (BBDB itself provides much
181 more flexible ways to do that), but rather to offer an interface to your
182 local directory that is consistent with the interface to external
183 directories (LDAP, PH/QI). This is particularly interesting when
184 performing queries on multiple servers.
185
186 EUDC also offers a means to insert results from directory queries into
187 your own local BBDB (@pxref{Creating BBDB Records})
188
189 @node Installation
190 @chapter Installation
191
192 Add the following to your @file{.emacs} init file:
193 @lisp
194 (require 'eudc)
195 @end lisp
196 This will install EUDC at startup.
197
198 After installing EUDC you will find (the next time you launch Emacs) a
199 new @code{Directory Search} submenu in the @samp{Tools} menu that will
200 give you access to EUDC.
201
202 You may also find it useful to add the following to your @file{.emacs}
203 initialization file to add a shortcut for email address expansion in
204 email composition buffers (@pxref{Inline Query Expansion})

221
222 LDAP support is added by means of @file{ldap.el}, which is part of Emacs.
223 @file{ldap.el} needs an external command line utility named
224 @file{ldapsearch}, available as part of Open LDAP
225 (@url{http://www.openldap.org/}).

247 @node Querying Servers
248 @section Querying Servers
249
250 EUDC's basic functionality is to let you query a directory server and
251 return the results back to you. There are several things you may want
252 to customize in this process.

260
261 @node Selecting a Server
262 @subsection Selecting a Server
263
264 Before doing any query you will need to set the directory server. You
265 need to specify the name of the host machine running the server software
266 and the protocol to use. If you do not set the server in any fashion,
267 EUDC will ask you for one when you make your first query.
268
269 You can set the server by selecting one from your hotlist of servers
270 (@pxref{The Server Hotlist}) available in the @samp{Server} submenu or
271 by selecting @samp{New Server} in that same menu.
272
273 LDAP servers generally require some configuration before you can perform
274 queries on them. In particular, the @dfn{search base} must be
275 configured. If the server you select has no configured search base then
276 EUDC will propose you to configure it at this point. A customization
277 buffer will be displayed where you can edit the search base and other
278 parameters for the server.
279
280 @defvar eudc-server
281 The name or IP address of the remote directory server. A TCP port number
282 may be specified by appending a colon and a number to the name of the
283 server. You will not need this unless your server runs on a port other
284 than the default (which depends on the protocol).
285 If the directory server resides on your own computer (which is the case
286 if you use the BBDB back end) then `localhost' is a reasonable value but
287 it will be ignored anyway.
288 @end defvar
289
290 @defvar eudc-protocol
291 The directory protocol to use to query the server. Currently supported
292 protocols in this version of EUDC are @code{ph}, @code{ldap} and @code{bbdb}.
293 @end defvar
294
295 @deffn Command eudc-set-server
296 This command accessible from @samp{New Server} submenu lets you specify a
297 new directory server and protocol.
298 @end deffn
299
300 @node Return Attributes
301 @subsection Return Attributes
302
303 Directory servers may be configured to return a default set of
304 attributes for each record matching a query if the query specifies none.
305 The variable @code{eudc-default-return-attributes} controls the return
306 attributes you want to see, if different from the server defaults.
307
308 @defvar eudc-default-return-attributes
309 A list of the default attributes to extract from directory entries. If
310 set to the symbol @code{all} then all available attributes are
311 returned. A value of @code{nil}, the default, means to return the
312 default attributes as configured in the server.
313 @end defvar
314
315 The server may return several matching records to a query. Some of the
316 records may however not contain all the attributes you requested. You can
317 discard those records.
318
319 @defopt eudc-strict-return-matches
320 If non-@code{nil}, entries that do not contain all the requested return
321 attributes are ignored. Default is @code{t}.
322 @end defopt
323
324 @node Duplicate Attributes
325 @subsection Duplicate Attributes
326
327 Directory standards may authorize different instances of the same
328 attribute in a record. For instance the record of a person may contain
329 several email fields containing different email addresses. When using
330 a QI directory server this is difficult to distinguish from attributes
331 having multi-line values such as the postal address that may contain a
332 line for the street and another one for the zip code and city name. In
333 both cases, EUDC will consider the attribute duplicated.
334
335 EUDC has several methods to deal with duplicated attributes. The
336 available methods are:
337
338 @table @code
339 @item list
340 Makes a list with the different values of the duplicate attribute. The
341 record is returned with only one instance of the attribute with a list
342 of all the different values as a value. This is the default method that
343 is used to handle duplicate fields for which no other method has been
344 specified.
345 @item first
346 Discards all the duplicate values of the field keeping only the first
347 one.
348 @item concat
349 Concatenates the different values using a newline as a separator. The
350 record keeps only one instance of the field the value of which is a
351 single multi-line string.
352 @item duplicate
353 Duplicates the whole record into as many instances as there are different
354 values for the field. This is the default for the email field. Thus a
355 record containing 3 different email addresses is duplicated into three
356 different records each having a single email address. This is
357 particularly useful in combination with @code{select} as the method to
358 handle multiple matches in inline expansion queries (@pxref{Inline Query
359 Expansion}) because you are presented with the 3 addresses in a
360 selection buffer
361 @end table
362
363 Because a method may not be applicable to all fields, the variable
364 @code{eudc-duplicate-attribute-handling-method} lets you specify either a
365 default method for all fields or a method for each individual field.
366
367 @defvar eudc-duplicate-attribute-handling-method
368 A method to handle entries containing duplicate attributes. This is
369 either an alist of elements @code{(@var{attr} . @var{method})}, or a symbol
370 @var{method}. The alist form of the variable associates a method to an
371 individual attribute name; the second form specifies a method applicable
372 to all attribute names. Available methods are: @code{list},
373 @code{first}, @code{concat}, and @code{duplicate} (see above). The default is
374 @code{list}.
375 @end defvar
376
377
378
379 @node Query Form
380 @section Query Form
381
382 The simplest way to query your directory server is to use the query
383 form. You display the query form with the @samp{Query with Form} menu
384 item or by invoking the command @kbd{M-x eudc-query-form}. The attribute
385 names presented in this form are defined by the
386 @code{eudc-query-form-attributes} variable (unless a non-@code{nil}
387 argument is supplied to @code{eudc-query-form}).
388
389 Since the different directory protocols to which EUDC interfaces may
390 use different names for equivalent attributes, EUDC defines its own set
391 of attribute names and a mapping between these names and their
392 protocol-specific equivalent through the variable
393 @code{eudc-protocol-attributes-translation-alist}. Names currently
394 defined by EUDC are @code{name}, @code{firstname}, @code{email} and
395 @code{phone}.
396
397 @defvar eudc-query-form-attributes
398 @findex eudc-get-attribute-list
399 A list of attributes presented in the query form. Attribute names in
400 this list should be either EUDC attribute names or valid attribute
401 names. You can get a list of valid attribute names for the current
402 protocol with the @samp{List Valid Attribute Names} menu item or the
403 @kbd{M-x eudc-get-attribute-list} command. Defaults to @code{name},
404 @code{email} and @code{phone}.
405 @end defvar
406
407 @deffn Command eudc-query-form get-fields-from-server
408 Display a form to query the directory server. If given a non-@code{nil}
409 argument the function first queries the server for the existing fields
410 and displays a corresponding form. Not all protocols may support a
411 non-@code{nil} argument here.
412 @end deffn
413
414 Since the names of the fields may not be explicit enough or adapted to
415 be directly displayed as prompt strings in the form, the variable
416 @code{eudc-user-attribute-names-alist} lets you define more explicit
417 names for directory attribute names. This variable is ignored if
418 @code{eudc-use-raw-directory-names} is non-@code{nil}.
419
420 @defvar eudc-user-attribute-names-alist
421 This is an alist of user-defined names for the directory attributes used in
422 query/response forms. Prompt strings for attributes that are not in this
423 alist are derived by splitting the attribute name at underscores and
424 capitalizing the individual words.
425 @end defvar
426
427 @defvar eudc-use-raw-directory-names
428 If non-@code{nil}, use attributes names as defined in the directory.
429 Otherwise, directory query/response forms display the user attribute
430 names defined in @code{eudc-user-attribute-names-alist}.
431 @end defvar
432
433 @node Display of Query Results
434 @section Display of Query Results
435
436 Upon successful completion of a form query, EUDC will display a buffer
437 containing the results of the query.
438
439 The fields that are returned for each record
440 are controlled by @code{eudc-default-return-attributes} (@pxref{Return
441 Attributes}).
442
443 The display of each individual field can be performed by an arbitrary
444 function which allows specific processing for binary values, such as
445 images or audio samples, as well as values with semantics, such as
446 URLs.
447
448 @defvar eudc-attribute-display-method-alist
449 An alist specifying methods to display attribute values. Each member of
450 the list is of the form @code{(@var{name} . @var{func})} where
451 @var{name} is a lowercased string naming a directory attribute
452 (translated according to @code{eudc-user-attribute-names-alist} if
453 @code{eudc-use-raw-directory-names} is non-@code{nil}) and @var{func} a
454 function that will be passed the corresponding attribute values for
455 display.
456 @end defvar
457
458 This variable has protocol-local definitions (see @pxref{Server/Protocol
459 Locals}). For instance, it is defined as follows for LDAP:
460
461 @lisp
462 (eudc-protocol-set 'eudc-attribute-display-method-alist
463 '(("jpegphoto" . eudc-display-jpeg-inline)
464 ("labeledurl" . eudc-display-url)
465 ("audio" . eudc-display-sound)
466 ("labeledurl" . eudc-display-url)
467 ("url" . eudc-display-url))
468 'ldap)
469 @end lisp
470
471 EUDC provides a set of built-in functions to display binary value types:
472
473 @defun eudc-display-generic-binary data
474 Display a button for unidentified binary @var{data}.
475 @end defun
476
477 @defun eudc-display-url url
478 Display URL and make it clickable.
479 @end defun
480
481 @defun eudc-display-sound data
482 Display a button to play the sound @var{data}.
483 @end defun
484
485 @defun eudc-display-jpeg-inline data
486 Display the JPEG @var{data} inline at point if possible.
487 @end defun
488
489 @defun eudc-display-jpeg-as-button data
490 Display a button for the JPEG @var{data}.
491 @end defun
492
493 Right-clicking on a binary value button pops up a contextual menu with
494 options to process the value. Among these are saving the attribute
495 value to a file or sending it to an external viewer command. External
496 viewers should expect the value on their standard input and should
497 display it or perform arbitrary processing on it. Messages sent to
498 standard output are discarded. External viewers are listed in the
499 variable @code{eudc-external-viewers} which you can customize.
500
501 @defvar eudc-external-viewers
502 This is a list of viewer program specifications. Each specification is
503 a list whose first element is a string naming the viewer for unique
504 identification, the second element is the executable program which
505 should be invoked and the following elements are arguments that should
506 be passed to the program.
507 @end defvar
508
509
510 @node Inline Query Expansion
511 @section Inline Query Expansion
512
513 Inline query expansion is a powerful method to get completion from your
514 directory server. The most common usage is for expanding names to email
515 addresses in mail message buffers. The expansion is performed by the
516 command @kbd{M-x eudc-expand-inline} which is available from the
517 @samp{Expand Inline Query} menu item but can also be conveniently
518 bound to a key shortcut (@pxref{Installation}). The operation is
519 controlled by the variables @code{eudc-inline-expansion-format},
520 @code{eudc-inline-query-format},
521 @code{eudc-expanding-overwrites-query} and
522 @code{eudc-multiple-match-handling-method}.
523
524 If the query fails for a server, other servers may be tried successively
525 until one of them finds a match (@pxref{Multi-server Queries}).
526
527 @deffn Command eudc-expand-inline replace-p
528 Query the server and expand the query string before point. The query
529 string consists of the buffer substring from the point back to the
530 preceding comma, colon or beginning of
531 line. @code{eudc-inline-query-format} controls how individual words
532 are mapped onto directory attribute names. After querying the server
533 for the given string, the expansion specified by
534 @code{eudc-inline-expansion-format} is inserted in the buffer at
535 point. If @var{replace-p} is @code{t} then this expansion replaces the
536 query string in the buffer. If @code{eudc-expanding-overwrites-query}
537 is non-@code{nil} then the meaning of @var{replace-p} is negated.
538 @end deffn
539
540 @defvar eudc-inline-query-format
541 Format of an inline expansion query.
542 This is actually a list of @var{format}s. A @var{format} is a list of
543 one or more EUDC attribute names. A @var{format} applies if it contains
544 as many attributes as individual words in the inline query string. If
545 several @var{format}s apply then they are tried in order until a match
546 is found. If @code{nil} all the words will be mapped onto the default
547 server/protocol attribute name (generally @code{name}).
548
549 For instance, use the following
550 @lisp
551 (setq eudc-inline-query-format '((name)
552 (firstname)
553 (firstname name)))
554 @end lisp
555 @noindent
556 to indicate that single word expansion queries are to be considered as
557 surnames and if no match is found then they should be tried as first
558 names. Inline queries consisting of two words are considered as
559 consisting of a first name followed by a surname. If the query consists
560 of more than two words, then the first one is considered as the first
561 name and the remaining words are all considered as surname constituents.
562
563 @var{format}s are in fact not limited to EUDC attribute names, you can
564 use server or protocol specific names in them. It may be safer if you
565 do so, to set the variable @code{eudc-inline-query-format} in a protocol
566 or server local fashion (see @pxref{Server/Protocol Locals}).

568 For instance you could use the following to match up to three words

579 @defvar eudc-inline-expansion-format
580 This variable lets you control exactly what is inserted into the buffer
581 upon an inline expansion request. It is a list whose first element is a
582 string passed to @code{format}. Remaining elements are symbols
583 corresponding to directory attribute names. The corresponding attribute
584 values are passed as additional arguments to @code{format}. Default is
585 @code{("%s" email)} but you may want to consider a value like @code{("%s
586 <%s>" name email)}
587 @end defvar
588
589 @defvar eudc-multiple-match-handling-method
590 This variable controls what to do when multiple entries match a query
591 for an inline expansion. Possible values are:
592 @table @code
593 @item first
594 The first match is considered as being the only one, the others are
595 discarded.
596 @item select
597 A selection buffer pops up where you can choose a particular match. This
598 is the default value of the variable.
599 @item all
600 The expansion uses all records successively
601 @item abort
602 An error is signaled. The expansion aborts.
603 @end table

610 @node The Server Hotlist
611 @section The Server Hotlist
612
613 EUDC lets you maintain a list of frequently used servers so that you
614 can easily switch from one to another. This hotlist appears in the
615 @samp{Server} submenu. You select a server in this list by clicking on
616 its name. You can add the current server to the list with the command
617 @kbd{M-x eudc-bookmark-current-server}. The list is contained in the variable
618 @code{eudc-server-hotlist} which is stored in and retrieved from the file
619 designated by @code{eudc-options-file}. EUDC also provides a facility to
620 edit the hotlist interactively (@pxref{The Hotlist Edit Buffer}).
621
622 The hotlist is also used to make queries on multiple servers
623 successively (@pxref{Multi-server Queries}). The order in which the
624 servers are tried is the order they appear in the hotlist, therefore it
625 is important to sort the hotlist appropriately.

716 @section Creating BBDB Records
717
718 @findex eudc-insert-record-at-point-into-bbdb
719 @findex eudc-try-bbdb-insert
720 With EUDC, you can automatically create BBDB records
721 (@pxref{Top,,BBDB,bbdb,BBDB Manual}) from records you get from a
722 directory server. You do this by moving point to the appropriate
723 record in a query result display buffer and invoking the command
724 @kbd{M-x eudc-insert-record-at-point-into-bbdb} with the
725 keyboard binding @kbd{b}@footnote{This key binding does not actually
726 call @code{eudc-insert-record-at-point-into-bbdb} but uses
727 @code{eudc-try-bbdb-insert} instead.}, or with the menu. EUDC
728 cannot update an existing BBDB record and will signal an error if you
729 try to insert a record matching an existing one.
730
731 @findex eudc-batch-export-records-to-bbdb
732 It is also possible to export to BBDB the whole batch of records
733 contained in the directory query result with the command
734 @kbd{M-x eudc-batch-export-records-to-bbdb}.
735
736 Because directory systems may not enforce a strict record format, local
737 server installations may use different attribute names and have
738 different ways to organize the information. Furthermore BBDB has its own
739 record structure. For these reasons converting a record from its
740 external directory format to the BBDB format is a highly customizable
741 process.
742
743 @defvar eudc-bbdb-conversion-alist
744 The value of this variable should be a symbol naming an alist defining a
745 mapping between BBDB field names onto directory attribute names records.
746 This is a protocol-local variable and is initialized upon protocol
747 switch (@pxref{Server/Protocol Locals}). The alist is made of cells of the
748 form @code{(@var{bbdb-field} . @var{spec-or-list})}.
749 @var{bbdb-field} is the name of a field
750 that must be defined in your BBDB environment (standard field names are
751 @code{name}, @code{company}, @code{net}, @code{phone}, @code{address}
752 and @code{notes}).
753 @var{spec-or-list} is either a single mapping specification or a list of
754 mapping specifications. Lists of mapping specifications are valid for
755 the @code{phone} and @code{address} BBDB fields only. @var{spec}s are
756 actually s-expressions which are evaluated as follows:
757
758 @table @asis
759 @item a string
760 evaluates to itself
761 @item a symbol
762 evaluates to the symbol value. Symbols corresponding to directory
763 attribute names present in the record evaluate to the value of the field
764 in the record
765 @item a form
766 is evaluated as a function. The argument list may contain attribute
767 names which evaluate to the corresponding values in the record. The form
768 evaluation should return something appropriate for the particular
769 @var{bbdb-field} (see @code{bbdb-create-internal}).
770 @code{eudc-bbdbify-phone} and @code{eudc-bbdbify-address} are provided as
771 convenience functions to parse phones and addresses.
772 @end table
773 @end defvar
774
775 The default value of the PH-specific value of that variable is
776 @code{eudc-ph-bbdb-conversion-alist}:
777
778 @lisp
779 ((name . name)
780 (net . email)
781 (address . (eudc-bbdbify-address address "Address"))
782 (phone . ((eudc-bbdbify-phone phone "Phone")
783 (eudc-bbdbify-phone office_phone "Office Phone"))))
784 @end lisp
785
786 This means that:
787
788 @itemize @bullet
789 @item
790 the @code{name} field of the BBDB record gets its value
791 from the @code{name} attribute of the directory record
792 @item
793 the @code{net} field of the BBDB record gets its value
794 from the @code{email} attribute of the directory record
795 @item
796 the @code{address} field of the BBDB record is obtained by parsing the
797 @code{address} attribute of the directory record with the function
798 @code{eudc-bbdbify-address}
799 @item
800 two @code{phone} fields are created (when possible) in the BBDB record.
801 The first one has @cite{Phone} for location and its value is obtained by
802 parsing the @code{phone} attribute of the PH/QI record with the function
803 @code{eudc-bbdbify-phone}. The second one has @cite{Office Phone} for location
804 its value is obtained by parsing the @code{office_phone} attribute of the
805 PH/QI record with the function @code{eudc-bbdbify-phone}.
806 @end itemize
807
808 @defun eudc-bbdbify-phone phone location
809 This is a convenience function provided for use in
810 @code{eudc-bbdb-conversion-alist}. It parses @var{phone} into a vector
811 compatible with @code{bbdb-create-internal}. @var{phone} is either a string
812 supposedly containing a phone number or a list of such strings which are
813 concatenated. @var{location} is used as the phone location for BBDB.
814 @end defun
815
816 @defun eudc-bbdbify-address addr location
817 This is a convenience function provided for use in
818 @code{eudc-bbdb-conversion-alist}. It parses @var{addr} into a vector
819 compatible with @code{bbdb-create-internal}. @var{addr} should be an
820 address string of no more than four lines or a list of lines. The last
821 line is searched for the zip code, city and state name. @var{location}
822 is used as the phone location for BBDB.
823 @end defun
824
825 Note that only a subset of the attributes you selected with
826 @code{eudc-default-return-attributes} and that are actually displayed may
827 actually be inserted as part of the newly created BBDB record.

847
848 The following predicates allow you to test the existence of
849 server/protocol local bindings for a particular variable.
850
851 @defun eudc-server-local-variable-p var
852 Return non-@code{nil} if @var{var} has server-local bindings

856 Return non-@code{nil} if @var{var} has protocol-local bindings
857 @end defun
858
859 The following functions allow you to set the value of a variable with
860 various degrees of locality.
861
862 @defun eudc-default-set var val
863 Set the EUDC default value of @var{var} to @var{val}.
864 The current binding of @var{var} (if local to the current server or
865 protocol) is not changed.
866 @end defun
867
868 @defun eudc-protocol-set var val &optional protocol
869 Set the binding of @var{var} local to @var{protocol} to @var{val}. If
870 omitted, @var{protocol} defaults to the current value of
871 @code{eudc-protocol}. The current binding of @var{var} is changed only
872 if @var{protocol} is omitted.
873 @end defun
874
875 @defun eudc-server-set var val &optional server
876 Set the binding of @var{var} local to @var{server} to @var{val}. If
877 omitted, @var{server} defaults to the current value of
878 @code{eudc-server}. The current binding of @var{var} is changed only if
879 @var{server} is omitted.
880 @end defun
881
882 @defun eudc-set var val
883 Set the most local (server, protocol or default) binding of @var{var} to
884 @var{val}. The current binding of @var{var} is also set to @var{val}.
885 @end defun
886
887 The following variables allow you to query the various bindings of a
888 variable (local or non-local).
889
890 @defun eudc-variable-default-value var
891 Return the default binding of @var{var} (outside of a particular server
892 or protocol local binding).
893 Return @code{unbound} if @var{var} has no EUDC default value.
894 @end defun
895
896 @defun eudc-variable-protocol-value var &optional protocol
897 Return the value of @var{var} local to @var{protocol}. Return
898 @code{unbound} if @var{var} has no value local to @var{protocol}.
899 @var{protocol} defaults to @code{eudc-protocol}.
900 @end defun
901
902 @defun eudc-variable-server-value var [server]
903 Return the value of @var{var} local to @var{server}.
904 Return @code{unbound} if @var{var} has no value local to @var{server}.
905 @var{server} defaults to @code{eudc-server}.
906 @end defun
907
908 Changing a protocol-local or server-local value of a variable has no
909 effect on its current value. The following command is used to
910 synchronize the current values of variables with their local values
911 given the current @code{eudc-server} and @code{eudc-protocol}:
