Syntaxrefer [-a] [-b] [-c] [-e] [-fn] [-kx] [-lm,n] [-n] [-p bib] [-skeys]
[-Bl.m] [-P] [-S] [file...]
Description
The command is a preprocessor for that finds and formats references for
footnotes or endnotes. It is also the base for a series of programs
designed to index, search, sort, and print stand-alone bibliographies,
or other data entered in the appropriate form.
Given an incomplete citation with sufficiently precise keywords, will
search a bibliographic database for references containing these key‐
words anywhere in the title, author, journal, and so forth. The input
file (or standard input) is copied to standard output, except for lines
between .[ and .] delimiters, which are assumed to contain keywords,
and are replaced by information from the bibliographic database. The
user may also search different databases, override particular fields,
or add new fields. The reference data, from whatever source, are
assigned to a set of strings. Macro packages such as print the fin‐
ished reference text from these strings. By default references are
flagged by footnote numbers.
Options
The following options are available:
-ar Reverses order of first author names. For example, Jones,
J. A. instead of J. A. Jones. If n is omitted all author
names are reversed.
-Bl.m Bibliography mode. Take a file composed of records sepa‐
rated by blank lines, and turn them into *roff input.
Label l is turned into the macro .m with l defaulting to %X
and .m defaulting to .AP (annotation paragraph).
-b Creates bare entries: no flags, numbers, or labels.
-ckeys Capitalizes fields whose key letters are in string.
-e Accumulates all references in one list. Default is to cre‐
ate references where encountered in text. Accumulate them
until a sequence of the form
.[
$LIST$
.]
is encountered, and then write out all references collected
so far.
-fn Set the footnote number to n instead of the default of 1
(one). With labels rather than numbers, this flag is a no-
op.
-kx Uses specified label in place of numbering for each refer‐
ence data line beginning % x :. By default x is L.
-lm,n Instead of numbering references, use labels made from the
senior author's last name and the year of publication.
Only the first m letters of the last name and the last n
digits of the date are used. If either m or n is omitted
the entire name or date respectively is used.
-P Places punctuation marks .,:;?! after the reference signal,
rather than before. (Periods and commas used to be done
with strings.)
-n Do not search the default file /usr/dict/papers/Ind. If
there is a REFER environment variable, the specified file
is searched instead of the default file; in this case the
-n flag has no effect.
-pbib Specifies file to be searched before
-S Produce references in the Natural or Social Science format.
-skeys Uses specified key in sorting references. Implies -e. The
key-letters in keys may be followed by a number to indicate
how many such fields are used, with + taken as a very large
number. The default is AD which sorts on the senior author
and then date; to sort, for example, on all authors and
then title use -sA+T.
To use your own references, put them in the format described below.
They can be searched more rapidly by running on them before using Fail‐
ure to index results in a linear search. When is used with the or pre‐
processors should be first, to minimize the volume of data passed
through pipes.
The preprocessor and associated programs expect input from a file of
references composed of records separated by blank lines. A record is a
set of lines (fields), each containing one kind of information. Fields
start on a line beginning with a ``%'', followed by a key-letter, then
a blank, and finally the contents of the field, and continue until the
next line starting with ``%''. The output ordering and formatting of
fields is controlled by the macros specified for (for footnotes and
endnotes) or (for stand-alone bibliographies). For a list of the most
common key-letters and their corresponding fields, see An example of a
entry is given below.
Restrictions
Blank spaces at the end of lines in bibliography fields will cause the
records to sort and reverse incorrectly. Sorting large numbers of ref‐
erences causes a core dump.
