122 | ||
123 | LDAP, @dfn{the Lightweight Directory Access Protocol}, is a communication | |
124 | protocol for directory applications defined in RFC 1777. | |
125 | ||
126 | Quoted from RFC 1777: | |
127 | ||
128 | @quotation | |
129 | [LDAP] is designed to provide access to the X.500 Directory while not | |
130 | incurring the resource requirements of the Directory Access Protocol | |
131 | (DAP). This protocol is specifically targeted at simple management | |
132 | applications and browser applications that provide simple read/write | |
133 | interactive access to the X.500 Directory, and is intended to be a | |
134 | complement to the DAP itself. | |
135 | @end quotation | |
136 | ||
137 | LDAP servers usually store (but are not limited to) information about | |
138 | people such as their name, phone number, email address, office | |
139 | location, etc@enddots{} More information about LDAP can be found at | |
e1a8c4c0 | 140 | @url{http://www.openldap.org/}. |

148 | @section CCSO PH/QI | |
149 | ||
150 | The Central Computing Services Office (CCSO) of the University of | |
e1a8c4c0 GM |
151 | Illinois at Urbana Champaign created and freely distributed a |
152 | directory system that was used by many organizations in the 1990s. | |
153 | The system records information about people such as their address, | |
154 | phone number, email, academic information or any other details it was | |
155 | configured to. Nowadays this system is not widely used. | |
4009494e GM |
156 | |
157 | The system consists of two parts: a database server traditionally called | |
e1a8c4c0 GM |
158 | @samp{qi} and a command-line client called @samp{ph}. As of 2010, the |
159 | code can still be downloaded from @url{http://www-dev.cites.uiuc.edu/ph/}. | |
4009494e GM |
160 | |
161 | The original command-line @samp{ph} client that comes with the | |
162 | @samp{ph/qi} distribution provides additional features like the | |
163 | possibility to communicate with the server in login-mode which makes it | |
164 | possible to change records in the database. This is not implemented in | |
165 | EUDC. | |
166 | ||
167 | ||

169 | @comment node-name, next, previous, up | |
170 | @section BBDB | |
171 | ||
172 | BBDB is the @dfn{Big Brother's Insidious Database}, a package for Emacs | |
173 | originally written by Jamie Zawinski which provides rolodex-like | |
174 | database functionality featuring tight integration with the Emacs mail | |
175 | and news readers. | |
176 | ||
177 | It is often used as an enhanced email address book. | |
178 | ||
179 | EUDC considers BBDB as a directory server back end just like LDAP or | |
180 | PH/QI servers, though BBDB has no client/server protocol and thus always | |
181 | resides locally on your machine. The point in this is not to offer an | |
182 | alternate way to query your BBDB database (BBDB itself provides much | |
183 | more flexible ways to do that), but rather to offer an interface to your | |
184 | local directory that is consistent with the interface to external | |
185 | directories (LDAP, PH/QI). This is particularly interesting when | |
186 | performing queries on multiple servers. | |
187 | ||
188 | EUDC also offers a means to insert results from directory queries into | |
189 | your own local BBDB (@pxref{Creating BBDB Records}) | |
190 | ||

196 | @lisp | |
197 | (require 'eudc) | |
198 | @end lisp | |
199 | This will install EUDC at startup. | |
200 | ||
201 | After installing EUDC you will find (the next time you launch Emacs) a | |
202 | new @code{Directory Search} submenu in the @samp{Tools} menu that will | |
203 | give you access to EUDC. | |
204 | ||
205 | You may also find it useful to add the following to your @file{.emacs} | |

254 | @section Querying Servers | |
255 | ||
256 | EUDC's basic functionality is to let you query a directory server and | |
257 | return the results back to you. There are several things you may want | |
258 | to customize in this process. | |

265 | @end menu | |
266 | ||
267 | @node Selecting a Server, Return Attributes, Querying Servers, Querying Servers | |
268 | @subsection Selecting a Server | |
269 | ||
270 | Before doing any query you will need to set the directory server. You | |
271 | need to specify the name of the host machine running the server software | |
272 | and the protocol to use. If you do not set the server in any fashion, | |
273 | EUDC will ask you for one when you make your first query. | |
274 | ||
275 | You can set the server by selecting one from your hotlist of servers | |
276 | (@pxref{The Server Hotlist}) available in the @samp{Server} submenu or | |
277 | by selecting @samp{New Server} in that same menu. | |
278 | ||
279 | LDAP servers generally require some configuration before you can perform | |
280 | queries on them. In particular, the @dfn{search base} must be | |
281 | configured. If the server you select has no configured search base then | |
282 | EUDC will propose you to configure it at this point. A customization | |
283 | buffer will be displayed where you can edit the search base and other | |
284 | parameters for the server. | |
285 | ||
286 | @defvar eudc-server | |
287 | The name or IP address of the remote directory server. A TCP port number | |
288 | may be specified by appending a colon and a number to the name of the | |
289 | server. You will not need this unless your server runs on a port other | |
290 | than the default (which depends on the protocol). | |
291 | If the directory server resides on your own computer (which is the case | |
292 | if you use the BBDB back end) then `localhost' is a reasonable value but | |
293 | it will be ignored anyway. | |
294 | @end defvar | |
295 | ||
296 | @defvar eudc-protocol | |
297 | The directory protocol to use to query the server. Currently supported | |
298 | protocols in this version of EUDC are @code{ph}, @code{ldap} and @code{bbdb}. | |
299 | @end defvar | |
300 | ||
301 | @deffn Command eudc-set-server | |
302 | This command accessible from @samp{New Server} submenu lets you specify a | |
303 | new directory server and protocol. | |
304 | @end deffn | |
305 | ||
306 | @node Return Attributes, Duplicate Attributes, Selecting a Server, Querying Servers | |
307 | @subsection Return Attributes | |
308 | ||
309 | Directory servers may be configured to return a default set of | |
310 | attributes for each record matching a query if the query specifies none. | |
311 | The variable @code{eudc-default-return-attributes} controls the return | |
312 | attributes you want to see, if different from the server defaults. | |
313 | ||
314 | @defvar eudc-default-return-attributes | |
315 | A list of the default attributes to extract from directory entries. If | |
316 | set to the symbol @code{all} then all available attributes are | |
317 | returned. A value of @code{nil}, the default, means to return the | |
318 | default attributes as configured in the server. | |
319 | @end defvar | |
320 | ||
321 | The server may return several matching records to a query. Some of the | |
322 | records may however not contain all the attributes you requested. You can | |
323 | discard those records. | |
324 | ||
325 | @defopt eudc-strict-return-matches | |
326 | If non-@code{nil}, entries that do not contain all the requested return | |
327 | attributes are ignored. Default is @code{t}. | |
328 | @end defopt | |
329 | ||
330 | @node Duplicate Attributes, , Return Attributes, Querying Servers | |
331 | @subsection Duplicate Attributes | |
332 | ||
333 | Directory standards may authorize different instances of the same | |
334 | attribute in a record. For instance the record of a person may contain | |
335 | several email fields containing different email addresses. When using | |
336 | a QI directory server this is difficult to distinguish from attributes | |
337 | having multi-line values such as the postal address that may contain a | |
338 | line for the street and another one for the zip code and city name. In | |
339 | both cases, EUDC will consider the attribute duplicated. | |
340 | ||
341 | EUDC has several methods to deal with duplicated attributes. The | |
342 | available methods are: | |
343 | ||
344 | @table @code | |
345 | @item list | |
346 | Makes a list with the different values of the duplicate attribute. The | |
347 | record is returned with only one instance of the attribute with a list | |
348 | of all the different values as a value. This is the default method that | |
349 | is used to handle duplicate fields for which no other method has been | |
350 | specified. | |
351 | @item first | |
352 | Discards all the duplicate values of the field keeping only the first | |
353 | one. | |
354 | @item concat | |
355 | Concatenates the different values using a newline as a separator. The | |
356 | record keeps only one instance of the field the value of which is a | |
357 | single multi-line string. | |
358 | @item duplicate | |
359 | Duplicates the whole record into as many instances as there are different | |
360 | values for the field. This is the default for the email field. Thus a | |
361 | record containing 3 different email addresses is duplicated into three | |
362 | different records each having a single email address. This is | |
363 | particularly useful in combination with @code{select} as the method to | |
364 | handle multiple matches in inline expansion queries (@pxref{Inline Query | |
365 | Expansion}) because you are presented with the 3 addresses in a | |
366 | selection buffer | |
367 | @end table | |
368 | ||
369 | Because a method may not be applicable to all fields, the variable | |
370 | @code{eudc-duplicate-attribute-handling-method} lets you specify either a | |
371 | default method for all fields or a method for each individual field. | |
372 | ||
373 | @defvar eudc-duplicate-attribute-handling-method | |
374 | A method to handle entries containing duplicate attributes. This is | |
375 | either an alist of elements @code{(@var{attr} . @var{method})}, or a symbol | |
376 | @var{method}. The alist form of the variable associates a method to an | |
377 | individual attribute name; the second form specifies a method applicable | |
378 | to all attribute names. Available methods are: @code{list}, | |
379 | @code{first}, @code{concat}, and @code{duplicate} (see above). The default is | |
380 | @code{list}. | |
381 | @end defvar | |
382 | ||
383 | ||
384 | ||
385 | @node Query Form, Display of Query Results, Querying Servers, Usage | |
386 | @comment node-name, next, previous, up | |
387 | @section Query Form | |
388 | ||
389 | The simplest way to query your directory server is to use the query | |
390 | form. You display the query form with the @samp{Query with Form} menu | |
391 | item or by invoking the command @kbd{M-x eudc-query-form}. The attribute | |
392 | names presented in this form are defined by the | |
393 | @code{eudc-query-form-attributes} variable (unless a non-@code{nil} | |
394 | argument is supplied to @code{eudc-query-form}). | |
395 | ||
396 | Since the different directory protocols to which EUDC interfaces may | |
397 | use different names for equivalent attributes, EUDC defines its own set | |
398 | of attribute names and a mapping between these names and their | |
399 | protocol-specific equivalent through the variable | |
400 | @code{eudc-protocol-attributes-translation-alist}. Names currently | |
401 | defined by EUDC are @code{name}, @code{firstname}, @code{email} and | |
402 | @code{phone}. | |
403 | ||
404 | @defvar eudc-query-form-attributes | |
405 | @findex eudc-get-attribute-list | |
406 | A list of attributes presented in the query form. Attribute names in | |
407 | this list should be either EUDC attribute names or valid attribute | |
408 | names. You can get a list of valid attribute names for the current | |
409 | protocol with the @samp{List Valid Attribute Names} menu item or the | |
410 | @kbd{M-x eudc-get-attribute-list} command. Defaults to @code{name}, | |
411 | @code{email} and @code{phone}. | |
412 | @end defvar | |
413 | ||
414 | @deffn Command eudc-query-form get-fields-from-server | |
415 | Display a form to query the directory server. If given a non-@code{nil} | |
416 | argument the function first queries the server for the existing fields | |
417 | and displays a corresponding form. Not all protocols may support a | |
418 | non-@code{nil} argument here. | |
419 | @end deffn | |
420 | ||
421 | Since the names of the fields may not be explicit enough or adapted to | |
422 | be directly displayed as prompt strings in the form, the variable | |
423 | @code{eudc-user-attribute-names-alist} lets you define more explicit | |
424 | names for directory attribute names. This variable is ignored if | |
425 | @code{eudc-use-raw-directory-names} is non-@code{nil}. | |
426 | ||
427 | @defvar eudc-user-attribute-names-alist | |
428 | This is an alist of user-defined names for the directory attributes used in | |
429 | query/response forms. Prompt strings for attributes that are not in this | |
430 | alist are derived by splitting the attribute name at underscores and | |
431 | capitalizing the individual words. | |
432 | @end defvar | |
433 | ||
434 | @defvar eudc-use-raw-directory-names | |
435 | If non-@code{nil}, use attributes names as defined in the directory. | |
436 | Otherwise, directory query/response forms display the user attribute | |
437 | names defined in @code{eudc-user-attribute-names-alist}. | |
438 | @end defvar | |

442 | @section Display of Query Results | |
443 | ||
444 | Upon successful completion of a form query, EUDC will display a buffer | |
445 | containing the results of the query. | |
446 | ||
447 | The fields that are returned for each record | |
448 | are controlled by @code{eudc-default-return-attributes} (@pxref{Return | |
449 | Attributes}). | |
450 | ||
451 | The display of each individual field can be performed by an arbitrary | |
452 | function which allows specific processing for binary values, such as | |
453 | images or audio samples, as well as values with semantics, such as | |
454 | URLs. | |
455 | ||
456 | @defvar eudc-attribute-display-method-alist | |
457 | An alist specifying methods to display attribute values. Each member of | |
458 | the list is of the form @code{(@var{name} . @var{func})} where | |

520 | @section Inline Query Expansion | |
521 | ||
522 | Inline query expansion is a powerful method to get completion from your | |
523 | directory server. The most common usage is for expanding names to email | |
524 | addresses in mail message buffers. The expansion is performed by the | |
525 | command @kbd{M-x eudc-expand-inline} which is available from the | |
526 | @samp{Expand Inline Query} menu item but can also be conveniently | |
527 | bound to a key shortcut (@pxref{Installation}). The operation is | |
528 | controlled by the variables @code{eudc-inline-expansion-format}, | |
529 | @code{eudc-inline-query-format}, | |
530 | @code{eudc-expanding-overwrites-query} and | |
531 | @code{eudc-multiple-match-handling-method}. | |
532 | ||
533 | If the query fails for a server, other servers may be tried successively | |
534 | until one of them finds a match (@pxref{Multi-server Queries}). | |
535 | ||
536 | @deffn Command eudc-expand-inline replace-p | |
537 | Query the server and expand the query string before point. The query | |
538 | string consists of the buffer substring from the point back to the | |
539 | preceding comma, colon or beginning of | |
540 | line. @code{eudc-inline-query-format} controls how individual words | |
541 | are mapped onto directory attribute names. After querying the server | |
542 | for the given string, the expansion specified by | |
543 | @code{eudc-inline-expansion-format} is inserted in the buffer at | |
544 | point. If @var{replace-p} is @code{t} then this expansion replaces the | |
545 | query string in the buffer. If @code{eudc-expanding-overwrites-query} | |
546 | is non-@code{nil} then the meaning of @var{replace-p} is negated. | |
547 | @end deffn | |
548 | ||
549 | @defvar eudc-inline-query-format | |
550 | Format of an inline expansion query. | |
551 | This is actually a list of @var{format}s. A @var{format} is a list of | |
552 | one or more EUDC attribute names. A @var{format} applies if it contains | |
553 | as many attributes as individual words in the inline query string. If | |
554 | several @var{format}s apply then they are tried in order until a match | |
555 | is found. If @code{nil} all the words will be mapped onto the default | |
556 | server/protocol attribute name (generally @code{name}). | |
557 | ||
558 | For instance, use the following | |
559 | @lisp | |
560 | (setq eudc-inline-query-format '((name) | |
561 | (firstname) | |
562 | (firstname name))) | |
563 | @end lisp | |
564 | @noindent | |
565 | to indicate that single word expansion queries are to be considered as | |
566 | surnames and if no match is found then they should be tried as first | |
567 | names. Inline queries consisting of two words are considered as | |
568 | consisting of a first name followed by a surname. If the query consists | |
569 | of more than two words, then the first one is considered as the first | |
570 | name and the remaining words are all considered as surname constituents. | |
571 | ||
572 | @var{format}s are in fact not limited to EUDC attribute names, you can | |
573 | use server or protocol specific names in them. It may be safer if you | |
574 | do so, to set the variable @code{eudc-inline-query-format} in a protocol | |
575 | or server local fashion (see @pxref{Server/Protocol Locals}). | |
576 | ||
577 | For instance you could use the following to match up to three words | |
578 | against the @code{cn} attribute of LDAP servers: | |
579 | @lisp | |
580 | (eudc-protocol-set 'eudc-inline-query-format | |
581 | '((cn) | |
582 | (cn cn) | |
583 | (cn cn cn)) | |
584 | 'ldap) | |
585 | @end lisp | |
586 | @end defvar | |
587 | ||
588 | @defvar eudc-inline-expansion-format | |
589 | This variable lets you control exactly what is inserted into the buffer | |
590 | upon an inline expansion request. It is a list whose first element is a | |
591 | string passed to @code{format}. Remaining elements are symbols | |
592 | corresponding to directory attribute names. The corresponding attribute | |
593 | values are passed as additional arguments to @code{format}. Default is | |
594 | @code{("%s" email)} but you may want to consider a value like @code{("%s | |
595 | <%s>" name email)} | |
596 | @end defvar | |
597 | ||
598 | @defvar eudc-multiple-match-handling-method | |
599 | This variable controls what to do when multiple entries match a query | |
600 | for an inline expansion. Possible values are: | |
601 | @table @code | |
602 | @item first | |
603 | The first match is considered as being the only one, the others are | |
604 | discarded. | |
605 | @item select | |
606 | A selection buffer pops up where you can choose a particular match. This | |
607 | is the default value of the variable. | |
608 | @item all | |
609 | The expansion uses all records successively | |
610 | @item abort | |
611 | An error is signaled. The expansion aborts. | |
612 | @end table | |

733 | With EUDC, you can automatically create BBDB records | |
734 | (@pxref{Top,,BBDB,bbdb,BBDB Manual}) from records you get from a | |
735 | directory server. You do this by moving point to the appropriate | |
736 | record in a query result display buffer and invoking the command | |
737 | @kbd{M-x eudc-insert-record-at-point-into-bbdb} with the | |
738 | keyboard binding @kbd{b}@footnote{This key binding does not actually | |
739 | call @code{eudc-insert-record-at-point-into-bbdb} but uses | |
740 | @code{eudc-try-bbdb-insert} instead.}, or with the menu. EUDC | |
741 | cannot update an existing BBDB record and will signal an error if you | |
742 | try to insert a record matching an existing one. | |
743 | ||
744 | @findex eudc-batch-export-records-to-bbdb | |
745 | It is also possible to export to BBDB the whole batch of records | |
746 | contained in the directory query result with the command | |
747 | @kbd{M-x eudc-batch-export-records-to-bbdb}. | |
748 | ||
749 | Because directory systems may not enforce a strict record format, local | |
750 | server installations may use different attribute names and have | |
751 | different ways to organize the information. Furthermore BBDB has its own | |
752 | record structure. For these reasons converting a record from its | |
753 | external directory format to the BBDB format is a highly customizable | |
754 | process. | |
755 | ||
756 | @defvar eudc-bbdb-conversion-alist | |
757 | The value of this variable should be a symbol naming an alist defining a | |
758 | mapping between BBDB field names onto directory attribute names records. | |
759 | This is a protocol-local variable and is initialized upon protocol | |
760 | switch (@pxref{Server/Protocol Locals}). The alist is made of cells of the | |
761 | form @code{(@var{bbdb-field} . @var{spec-or-list})}. | |
762 | @var{bbdb-field} is the name of a field | |
763 | that must be defined in your BBDB environment (standard field names are | |
764 | @code{name}, @code{company}, @code{net}, @code{phone}, @code{address} | |
765 | and @code{notes}). | |
766 | @var{spec-or-list} is either a single mapping specification or a list of | |
767 | mapping specifications. Lists of mapping specifications are valid for | |
768 | the @code{phone} and @code{address} BBDB fields only. @var{spec}s are | |
769 | actually s-expressions which are evaluated as follows: | |
770 | ||
771 | @table @asis | |
772 | @item a string | |
773 | evaluates to itself | |
774 | @item a symbol | |
775 | evaluates to the symbol value. Symbols corresponding to directory | |
776 | attribute names present in the record evaluate to the value of the field | |
777 | in the record | |
778 | @item a form | |
779 | is evaluated as a function. The argument list may contain attribute | |
780 | names which evaluate to the corresponding values in the record. The form | |
781 | evaluation should return something appropriate for the particular | |
782 | @var{bbdb-field} (see @code{bbdb-create-internal}). | |
783 | @code{eudc-bbdbify-phone} and @code{eudc-bbdbify-address} are provided as | |
784 | convenience functions to parse phones and addresses. | |
785 | @end table | |
786 | @end defvar | |
787 | ||
788 | The default value of the PH-specific value of that variable is | |

899 | @var{val}. The current binding of @var{var} is also set to @var{val}. | |
900 | @end defun | |
901 | ||
902 | The following variables allow you to query the various bindings of a | |
903 | variable (local or non-local). | |
904 | ||
905 | @defun eudc-variable-default-value var | |
906 | Return the default binding of @var{var} (outside of a particular server | |
907 | or protocol local binding). | |
908 | Return @code{unbound} if @var{var} has no EUDC default value. | |
909 | @end defun | |
910 | ||
911 | @defun eudc-variable-protocol-value var &optional protocol | |
912 | Return the value of @var{var} local to @var{protocol}. Return | |
913 | @code{unbound} if @var{var} has no value local to @var{protocol}. | |
914 | @var{protocol} defaults to @code{eudc-protocol}. | |
915 | @end defun | |
916 | ||
917 | @defun eudc-variable-server-value var [server] | |
918 | Return the value of @var{var} local to @var{server}. | |
919 | Return @code{unbound} if @var{var} has no value local to @var{server}. | |
920 | @var{server} defaults to @code{eudc-server}. | |
921 | @end defun | |
922 | ||
923 | Changing a protocol-local or server-local value of a variable has no | |
924 | effect on its current value. The following command is used to | |
925 | synchronize the current values of variables with their local values | |
926 | given the current @code{eudc-server} and @code{eudc-protocol}: | |
927 | ||
928 | @defun eudc-update-local-variables | |
929 | Update all EUDC variables according to their local settings. | |
930 | @end defun | |
