;;; Commentary:

;; This file lets you feed BBDB into LaTeX.
;; See the BBDB info manual for documentation.
;;
;; In the *BBDB* buffer, type M-x `bbdb-tex' to convert the listing
;; to LaTeX format.
;;
;; TeX macros appearing in the output:
;;   \name{first}{last}
;;   \organization{foo bar}
;;   \affix{foo bar}
;;   \aka{foo bar}
;;   \phone{key}{123 456 7890}
;;   \address{key}{foo bar}
;;   \mail{foo@bar.com}{Smith <foo@bar.com>}
;;   \xfield{key}{value}
;; Each macro may appear multiple times.
;;
;; The detailed grammar of the output is defined in `bbdb-tex-alist'.
;; The output starts with a prolog where you can specify LaTeX packages
;; and other customizations in the usual way.  The above macros should get
;; defined, too. By default, this happens in the style file bbdb.sty that
;; is shipped with BBDB.
;;
;; The body of the output contains the BBDB records.  Usually, the records
;; are placed inside some "bbdb" environment.  You can customize which fields
;; of each record should appear in the listing and in which order.
;; Also, you can put separators between individual fields.  A separator macro
;; can also separate records when the first character of the last name differs
;; from the first character of the last name of the previous record.
;; The listing ends with an epilog.

;; A few notes on "advanced usage" of `bbdb-tex':
;;
;; It should be possible to use `bbdb-tex' with all the bells and whistles
;; of LaTeX by loading the appropriate LaTeX style files and packages or
;; embedding the output of `bbdb-tex' into more complex LaTeX documents.
;; For this you can customize the rules in `bbdb-tex-alist' and use
;; customized style files for interpreting the TeX macros used by `bbdb-tex'.
;;
;; Generally, lisp customizations for `bbdb-tex' are intended to provide control
;; of *what* appears in the TeX listing.  But there are no lisp customization
;; options to control the actual layout that should be handled by LaTeX.
;; BBDB is shipped with one basic LaTeX style file bbdb.sty to handle
;; the TeX macros listed above.  You should customize this LaTeX style file
;; to match your taste and / or your needs.  Note also that `bbdb-tex-alist'
;; allows you to specify an arbitrary number of rules that may use different
;; style files for the above TeX macros.

;; Generally, it will be advantageous to make all relevant style files
;; and packages known to LaTeX by putting them in the appropriate directories
;; of your TeX installation.  Likely, the user variable `bbdb-tex-path'
;; should not be used in such advanced cases.  The main purpose of the
;; inlining mechanism provided via `bbdb-tex-path' is that we can ship
;; and install BBDB without worrying about the tricky question where to
;; (auto-) install the basic style file bbdb.sty shipped with BBDB so that
;; TeX finds it.  Most often, it will be best to manually install even bbdb.sty
;; in a directory where TeX finds it and bind `bbdb-tex-path' to t to fully
;; suppress the inlining.
;;
;; Before generating the TeX output, the field values of a record are massaged
;; by `bbdb-tex-field' that passes these values by default to `bbdb-tex-replace',
;; see also `bbdb-tex-replace-list'.  Instead the user may also define functions
;; `bbdb-tex-output-...' that take precedence, see `bbdb-tex-field'.
;;
;; `bbdb-tex' understands one new BBDB xfield: tex-name, see also
;; `bbdb-tex-name'.  If this xfield is defined for a record,
;; this will be used for the TeXed listing instead of the name field
;; of that record.  The value of the xfield tex-name is used verbatim,
;; it does not see `bbdb-tex-field' and `bbdb-tex-replace-list'.
;;
;;
;; This program was adapted for BBDB by Boris Goldowsky
;; <boris@cs.rochester.edu> and Dirk Grunwald
;; <grunwald@cs.colorado.edu> using a TeX format designed by Luigi
;; Semenzato <luigi@paris.cs.berkeley.edu>.
;; We are also grateful to numerous people on the bbdb-info
;; mailing list for suggestions and bug reports.

  "Alist of rules for passing BBDB to LaTeX.
Each rule has the form (RULE LIST1 LIST2 ...).
The symbol RULE identifies the rule.
The remainder are lists LIST that should have one of these forms:

 (demand FORM)

  Here FORM is a lisp expression.  A record will be TeXed only
  if evaluating FORM yields a non-nil value for this record.
  When FORM is evaluated, the symbols name, affix, organization, mail,
  phone, address, and xfields are set to the corresponding values
  of this record; these symbols are nil if the respective field
  does not exist for this record.

 (prolog STRING)

  The string STRING is inserted at the beginning of the buffer.
  If STRING contains the substring \"\\usepackage{foo}\" and
  a file \"foo.sty\" exists within `bbdb-tex-path', replace
  \"\\usepackage{foo}\" with the content of the file \"foo.sty\",
  surrounded by \"\\makeatletter\" and \"\\makeatother\".
  Note: This fails with more sophisticated LaTeX style files
  using, e.g., optional arguments for the \"\\usepackage\" macro.

 (record ELT1 ELT2 ...)

  Here ELT may be one of the following:

  IF ELT is name, this expands to \"\\name{first}{last}\"

  If ELT is affix, organization, or aka, ELT expands to \"\\ELT{value}\".
    Here the elements of ELT are concatenated to get one value.

  If ELT is the key of an xfield, ELT expands to \"\\xfield{ELT}{value}\".

  If ELT is a string, this is inserted \"as is\" in the TeX buffer.

  ELT may also be a loop (FLD COUNT [SEPARATOR] [OPT...])
  looping over the values of FLD.

  If FLD is mail, this expands to \"\\mail{short}{long}\",
    such as \"\\mail{foo@bar.com}{Smith <foo@bar.com>}\",
  If FLD is phone, this expands to \"\\phone{key}{number}\"
  If FLD is address, this expands to \"\\address{key}{value}\".
  If FLD is xfields, this expands to \"\\xfield{key}{value}\".
  If FLD is the key of an xfield, split the value of FLD
    using `bbdb-separator-alist' to generate a list of values,
    which then expand to \"\\xfield{FLD}{value}\".

  If COUNT is a number, process at most COUNT values of FLD.
  IF COUNT is t, process all values of FLD.

  If SEPARATOR is non-nil, it is a string that is inserted between
  the values of FLD.  Insert COUNT - 1 instances of SEPARATOR,
  even if there are fewer values of FLD.

  If FLD is mail, phone, address, or xfields,
  OPT may be a list (admit KEY ...) or (omit KEY ...).
  Then a value is admitted or omitted if its key KEY is listed here.

 (separator STRING)

  When the first letter of the records' sortkey increases compared with
  the previous record in the TeX listing, the new letter is formatted
  using the format string STRING to generate a separator macro.

 (epilog STRING)

  The string STRING is inserted at the end of the buffer."
