6. Skribilo User Manual — Bibliographies |
Skribilo provides support for bibliographies. To setup a bibliography database and to be able to refer to its entries from a document, the following things must be done:
bibliography function.ref
:bibThis section describes functions dealing with bibliography tables. Essentially, bibliography tables are the representation of your bibliographies used by Skribilo at run-time.
The predicate bib-table? returns #t if and only
if its argument is a bibliography table as returned by
make-bib-table or *bib-table*. Otherwise
bib-table? returns #f.
(bib-table? obj)obj The value to be testedThe function *bib-table* returns a global, pre-existing
bibliography-table:
(*bib-table*)Technically, *bib-table* is actually an SRFI-39
parameter object, so it can be queried and modified like any other
parameter object.
The function make-bib-table constructs a new
bibliography-table:
(make-bib-table ident)ident The name of the bibliography table.The bibliography function loads bibliography entries
into the bibliography table specified using the :bib-table
parameter. It can be passed either lists representing entries (such as
an article or book reference), or strings denoting the names of files
that contains several entries. All the entries loaded in memory can
then be referred to with ref. A bibliography database
must be loaded before any reference is introduced. It is
advised to place the bibliography function call before
the call to the document function call.
(bibliography [:bib-table (*bib-table*)] [:command] entry...)~a is replaced
with the name of the file when the command is invoked. html lout latex context info xml entry... If entry is a string, it denotes
a file containing the entry (see bibliograph path). Otherwise, it is a list described
by the syntax
below.Files passed as an argument to bibliography are
searched in the current bibliography path, which is defined by
the *bib-path* SRFI-39 parameter. This parameter
contains a list of directories and its value can be obtained using
(*bib-path*). Its value can be altered using the -B command-line option of the skribilo compiler (see Chapter 14 for details).
The :command option can be used to import foreign bibliography. The following example, shows how to directly use a BibTeX bibliography using the Skribebibtex translator.
The Skribe/Skribilo bibliography database uses a format very close to the BibTeX one, which is a parenthetic version of BibTeX. Here is the syntax of an entry:
<entry> --> (<kind> <key> <field>+) <kind> --> techreport | article | inproceedings | book <key> --> <symbol> | <string> <field> --> (<symbol> <string>)
BibTeX files cannot be directly loaded but the tool skribebibtex can be use to automatically convert BibTeX format to Skribe bibliography format. Here is an example of a simple Skribe database.

The function the-bibliography displays the bibliography.
(the-bibliography :pred [:labels 'number] [:count 'partial] [:sort bib-sort/authors] [:bib-table (*bib-table*)])the-bibliography node. html lout latex context info xml number, uses
numbers to identify references, e.g., "[7]".
When name+year is chosen, long labels
including the first author's last name (and
optionally the second author's last name) and
the year of publication will be used. For
instance: "[Smith 1984]",
"[Smith & Johnson 1979]", or
"[Smith et al. 1980]". html lout latex context info xml Note that the name+year label style will only work if the
following conventions are followed by the author field of your
bibliography entries:
author fields of bibliographic entries should
be a string containing a comma-separated list of full author names;first-name second-name ... last-name.name+year label style, it is sometimes
desirable to preclude automatic abbreviations for some authors, e.g.,
when the author is the name of a consortium or company rather than that
of a person. In that case, you should enclose the value of your author field in a noabbrev
markup.(noabbrev [:class] [:ident])the-bibliography , bib-sort/first-author-last-name .The following example illustrates typical use of a bibliography.

Note that the current locale setting affects the language used in
bibliography entries. For instance, if the LC_ALL environment
variable is set to sv_SE.utf8, then phrases like ``Chapter''
or ``Technical Report'' will be written in Swedish.
The :pred option is bound to a function of one argument
that filters bibliography entries. It is used to control which entries
must appears on a bibliography. The default behavior is to display
only the entries referenced to in the text. For instance, in order to
display all the entries of a bibliography, is it needed to
print the bibliography with a predicate returning always #t.

The second example, filters out the entries that are not book or that are not referenced to from the document.

The last example, illustrates how to change the rendering of a
bibliography. It uses the [?mark processor: skribilo/documentation/manual.scm:315:4:] construction
and it defines two [?ident writer: ./bib.skb:252:21:] for
displaying &bib-entry-ident and &bib-entry-title
markups. These two markups are introduced by Skribe when it loads a
bibliography. All fields of bibliography entries are represented by
markups whose prefix are &bib-entry-. The parent of all these
markups is the bibliography entry itself. The &bib-entry- markups
are options of there parent.
(center (frame :border 1 :margin 2 :width 90. (processor :engine (make-engine '_ :filter string-upcase) :combinator (lambda (e1 e2) (let ((e (copy-engine '_ e2))) (markup-writer '&bib-entry-ident e :action (lambda (n e) (let* ((be (ast-parent n)) (o (markup-option be 'author)) (y (markup-option be 'year))) (output (markup-body o) e1) (display ":") (output (markup-body y) e)))) (markup-writer '&bib-entry-title e :action (lambda (n e) (evaluate-document (it (markup-body n)) e))) e)) (the-bibliography :pred (lambda (m n) (eq? (markup-option m 'kind) 'book))))))
... produces:

The :sort option of the the-bibliography
markup is used for sorting the bibliography entries. There are three
pre-existing functions for sorting entries, defines in the (skribilo biblio) module (see Section 1.5).
(bib-sort/authors l)(bib-sort/idents l)(bib-sort/dates l)l The list of entries.bib-sort/first-author-last-name .The first function sorts the entries according to an alphabetic ordering on authors. The second sorts according to an alphabetic ordering on entries identifier. The last one sorts according to entries date.
In addition, the (skribilo biblio author) module exports
a fourth procedure that sorts bibliography entries:
(bib-sort/first-author-last-name entries)entries The list of entries.This procedure allows entries to be sorted according to the last
name of the first author of each bibliography entry. For this to work,
the author field of bibliography entries must follow the same
conventions as for the name+year label style of the-bibliography.
FIXME: This tool is not available as of Skribilo version 0.10.0.
