% BibTeX styles for various physics journals (27-Feb-1990).
% This file, physics.btx, is based on the file btxbst.doc.
        % Please notify Charles Karney (Karney@Princeton.EDU)
        % of any bugs, improvements, etc.
% Run this file through cpp to get specific versions.  I have written
% a version of cpp within Emacs.  To access it put
%       (autoload 'cpp "tex$bibtex:cpp"         ; Use cpp for BibTeX styles
%                 "C preprocessor"
%                 t)
% into your .emacs file.  Read in this file with
%       emacs tex$bibtex:physics.btx
% and run cpp with e.g.,
%       M-x cpp <ret> aip <ret>
% Save the resulting file to tex$latex:aip.bst.
% To accomodate the variations we need (in addition to the definitions below)
%       ATIT_SUPPRESS:  do not include the titles of journal articles
%       NAME_INVERT:    put the initials last
%       NAME_UPPER:     convert names to all caps.
%       MONTH_SUPPRESS: do not include months in journal articles
%       PAREN_DATE:     dates go in parens in journal articles
%       DATE_FIRST:     dates go before page numbers
%       VOLUME_SPACE:   volume set off with space (not colon)
%       NUM_SUPPRESS:   do not include numbers in journal articles
%       BOLD_VOL:       volume numbers in bold face in journal articles
%       BRACKET_NOTE:   notes in brackets
%       PAGE_START_J:   include only starting page for journal articles
%       PAGE_START_O:   include only starting page for other entries
%       PAGE_ABBREV:    abbreviate page to p. and pages to pp.
%       PHYSICS_JOUR:   include abbreviations for Physics journals
%       COMMA_DELIMIT:  use comma (instead of period) to divide a citation
%       NOTE_SUPPRESS:  suppress the note
%       MAX_NAMES:      max number of authors before using et al (0 = infinity)
%       MIN_NAMES:      number of authors to list with et al.
%       EDIT_VAR:       use "edited by ..." instead of "..., editors"
%       RMP_LABELS:     create RMP-style labels
%       KEY_CITE:       use key as label
%       NAMED_REFS:     use (Smith, 1988) style of citations
%       CSC_NAMES:      names set in caps and small caps
%       JOUR_DEEMPH:    don't emphasize journal name
%       ETAL_EMPH:      emphasize et al.
%       ALT_INCOLL      alternate ordering of fields in incollections
% These are all boolean (0 or 1) except for MAX_NAMES and MIN_NAMES.
% These need to satisfy 0 <= MIN_NAMES <= MAX_NAMES.
% The rule here is that if all these are defined to be zero, we revert to
% the standard styles.  For that reason we initialize them all to 0.
% These are the original macros

        % This restriction helps ensure that all standard styles are identical.

%
% This is file btxbxt.doc; it helps document bibliography styles,
% and is also a template file that you can use to make
% several different style files, if you have access to a C preprocessor.
% For example, the standard styles were made by doing something like
%       cpp -P -DPLAIN btxbst.doc plain.txt
%       cpp -P -DUNSRT btxbst.doc unsrt.txt
%       cpp -P -DALPHA btxbst.doc alpha.txt
%       cpp -P -DABBRV btxbst.doc abbrv.txt
% and then renaming after removing unwanted comments and blank lines.
% If you don't have access,
% you can edit this file by hand to imitate the preprocessor,
% with the following explanation of the C preprocessor constructs used here.
%
% The output of the preprocessor is the same as the input, except that certain
% lines will be excluded (and some blank lines will be added).  The sequence
%       #if VAR
%           lines to be included when VAR is not zero
%       #else
%           lines to be included when VAR is zero
%       #endif
% (with the #-signs appearing in column 1) means that one set or the other of
% the lines are to be included depending on the value of VAR.
% The #else part is optional.  Comments can be added after #else and #endif.
% Variables can be set by
%       #define VAR value
% and one can also use #ifdef VAR to see if VAR has any value, and #ifndef
% to see if it has none.
% Another #if form used in this file is #if !VAR, which includes the lines
% after the #if only if VAR is zero.
%
% Convention: Use all uppercase identifiers for these preprocessor variables
% so you can spot them easily
%
% The command line to the preprocessor should define one of PLAIN, UNSRT, ALPHA
% or ABBRV (though PLAIN will be used by default if none is given),
% and the following lines will set various boolean variables to control the
% various lines that are chosen from the rest of the file.
% Each boolean variable should be set true (1) or false (0) in each style.
% Here are the current variables, and their meanings:
%       0 :     an alphabetic label is used (if false then a numeric
%                           label is used)
%       0 :             the entries should be sorted by label (if nonnumeric)
%                           and other info, like authors (if false, then
%                           entries remain in order of occurrence)
%       0 :     the authors, editors, etc., get the full names as
%                           given in the bibliography file (if false, the first
%                           names become initials)
%       1 :     titles of non-"books" (e.g., articles) should be
%                           converted to lower-case, except the first letter or
%                           first letter after a colon
%                           (if false then they appear as in the database)
%       0 :     months are spelled out in full (if false, then
%                           they're abbreviated)
%       0 :     macro journal names are spelled out in full
%                           (if false then they are abbreviated, currently
%                           as they appear in ACM publications)
%#          define PLAIN 1
%
%   Entry formatting: Similar to that recommended by Mary-Claire van Leunen
%       in "A Handbook for Scholars".  Book-like titles are italicized
%       (emphasized) and non-book titles are converted to sentence
%       capitilization (and not enclosed in quotes).
%       This file outputs a \newblock between major blocks of an entry
%       (the name \newblock is analogous to the names \newline and \newpage)
%       so that the user can obtain an "open" format, which has a line break
%       before each block and lines after the first are indented within blocks,
%       by giving the optional \documentstyle argument `openbib';
%       The default is the "closed" format---blocks runs together.
%
%   Citation alphabetic label format:
%               [Knu73] for single author (or editor or key)
%               [AHU83] (first letters of last names) for multiple authors
%
%   Citation label numberic format:
%               [number]
%
%   Reference list ordering for sorted, alphabetic lables:
%               alphabetical by citation label, then by author(s) or whatever
%               passes for author in the absence of one, then by year,
%               then title
%
%   Reference list ordering for sorted, numeric lables:
%               alphabetical by author(s) or whatever passes
%               for author in the absence of one, then by year, then title
%
%   Reference list ordering for unsorted:
%               by the order cited in the text

%   History
%   12/16/84    (HWT)   Original `plain' version, by Howard Trickey.
%   12/23/84    (LL)    Some comments made by Leslie Lamport.
%    2/16/85    (OP)    Changes based on LL's comments, Oren Patashnik.
%    2/17/85    (HWT)   Template file and other standard styles made.
%    3/28/85    (OP)    First release, version 0.98b for BibTeX 0.98f.
%    5/ 9/85    (OP)    Version 0.98c for BibTeX 0.98i:
%                       fixed Theoretical Computer Science macro name;
%                       fixed the format.vol.num.pages function.
%    1/24/88    (OP)    Version 0.99a for BibTeX 0.99a, main changes:
%                       assignment operator (:=) arguments reversed;
%                       the preamble$ function outputs the database PREAMBLE;
%                       entry.max$ and global.max$ (built-in) variables replace
%                       entry.string.max and global.string.max functions;
%                       alphabetizing by year then title, not just title;
%                       many unnecessary ties removed; \it ==> \em;
%                       the `alpha' style uses a superscripted `+' instead of a
%                       `*' for unnamed names in constructing the label;
%                       the `abbrv' style now uses "Mar." and "Sept.";
%                       the functions calc.label and presort now look at just
%                       the fields they're supposed to;
%                       BOOKLET, MASTERSTHESIS, TECHREPORT use nonbook titles;
%                       INBOOK and INCOLLECTION take an optional type (e.g.
%                       type = "Section"), overriding the default "chapter";
%                       BOOK, INBOOK, INCOLLECTION, and PROCEEDINGS now allow
%                       either volume or number, not just volume;
%                       INCOLLECTION now allows an edition and series field;
%                       PROCEEDINGS and INPROCEEDINGS now use the address field
%                       to tell where a conference was held;
%                       INPROCEEDINGS and PROCEEDINGS now allow either volume
%                       or number, and also a series field;
%                       MASTERSTHESIS and PHDTHESIS accept types other than
%                       "Master's thesis" and "PhD thesis";
%                       UNPUBLISHED now outputs, in one block, note then date;
%                       MANUAL now prints out the organization in
%                       the first block if the author field is empty;
%                       MISC can't be empty---it requires some optional field.
%    3/23/88    (OP)    Version 0.99b for BibTeX 0.99c---changed the three
%                       erroneous occurrences of `cite ' to `cite$ '; this
%                       change didn't affect the four standard styles, so the
%                       0.99a versions of those styles are still current.
%
% The ENTRY declaration
%   Like Scribe's (according to pages 231-2 of the April '84 edition),
%   but no fullauthor or editors fields because BibTeX does name handling.
%   The annote field is commented out here because this family doesn't
%   include an annotated bibliography style.  And in addition to the fields
%   listed here, BibTeX has a built-in crossref field, explained later.
ENTRY
% Fields:
  { address
%           Usually the address of a publisher or other type of organization.
%           Put information in this field only if it helps the reader find the
%           thing---for example you should omit the address of a major
%           publisher entirely.  For a PROCEEDINGS or an INPROCEEDINGS,
%           however, it's the address of the conference; for those two entry
%           types, include the publisher's or organization's address, if
%           necessary, in the publisher or organization field.
%    annote
%           Long annotation---for annotated bibliographies (begins sentence).
    author
%           Name(s) of author(s), in BibTeX name format.
    booktitle
%           Book title when the thing being referenced isn't the whole book.
%           For book entries, the title field should be used instead.
    chapter
%           Chapter (or section or whatever) number.
    collaboration
    edition
%           Edition of a book---should be an ordinal (e.g., "Second").
    editor
%           Name(s) of editor(s), in BibTeX name format.
%           If there is also an author field, then the editor field should be
%           for the book or collection that the work appears in.
    howpublished
%            How something strange has been published (begins sentence).
    institution
%           Sponsoring institution of a technical report.
    journal
%           Journal name (macros are provided for many).
    key
%           Alphabetizing, labeling, and cross-referencing key
%           (needed when an entry has no author or editor).
    month
%           Month (macros are provided).
    note
%           To help the reader find a reference (begins sentence).
    eprint
%           ArXiv identifier
    number
%           Number of a journal or technical report, or of a work in a series.
    organization
%           Organization sponsoring a conference (or publishing a manual); if
%           the editor (or author) is empty, and if the organization produces
%           an awkward label or cross reference, you should put appropriately
%           condensed organization information in the key field as well.
    pages
%           Page number or numbers (use `--' to separate a range, use `+'
%           to indicate pages following that don't form a simple range).
    publisher
%           Publisher name.
    school
%           School name (for theses).
    series
%           The name of a series or set of books.
%           An individual book will will also have it's own title.
    title
%           The title of the thing you're referred to.
    type
%           Type of a Techreport (e.g., "Research Note") to be used instead of
%           the default "Technical Report"; or, similarly, the type of a
%           thesis; or of a part of a book.
    volume
%           The volume number of a journal or multivolume work.
    year
%           The year should contain only numerals (technically, it should end
%           with four numerals, after purification; doesn't a begin sentence).
    url
  }
% There are no integer entry variables
  {}
% These string entry variables are used to form the citation label.
% In a storage pinch, sort.label can be easily computed on the fly.
  { label }
% Each entry function starts by calling output.bibitem, to write the
% \bibitem and its arguments to the .BBL file.  Then the various fields
% are formatted and printed by output or output.check.  Those functions
% handle the writing of separators (commas, periods, \newblock's),
% taking care not to do so when they are passed a null string.
% Finally, fin.entry is called to add the final period and finish the
% entry.
%
% A bibliographic reference is formatted into a number of `blocks':
% in the open format, a block begins on a new line and subsequent
% lines of the block are indented.  A block may contain more than
% one sentence (well, not a grammatical sentence, but something to
% be ended with a sentence ending period).  The entry functions should
% call new.block whenever a block other than the first is about to be
% started.  They should call new.sentence whenever a new sentence is
% to be started.  The output functions will ensure that if two
% new.sentence's occur without any non-null string being output between
% them then there won't be two periods output.  Similarly for two
% successive new.block's.
%
% The output routines don't write their argument immediately.
% Instead, by convention, that argument is saved on the stack to be
% output next time (when we'll know what separator needs to come
% after it).  Meanwhile, the output routine has to pop the pending
% output off the stack, append any needed separator, and write it.
%
% To tell which separator is needed, we maintain an output.state.
% It will be one of these values:
%       before.all              just after the \bibitem
%       mid.sentence            in the middle of a sentence: comma needed
%                                       if more sentence is output
%       after.sentence          just after a sentence: period needed
%       after.block             just after a block (and sentence):
%                                       period and \newblock needed.
% Note: These styles don't use after.sentence
%
% VAR: output.state : INTEGER           -- state variable for output
%
% The output.nonnull function saves its argument (assumed to be nonnull)
% on the stack, and writes the old saved value followed by any needed
% separator.  The ordering of the tests is decreasing frequency of
% occurrence.
%
% output.nonnull(s) ==
%  BEGIN
%       s := argument on stack
%       if output.state = mid.sentence then
%           write$(pop() * ", ")
%                 -- "pop" isn't a function: just use stack top
%       else
%           if output.state = after.block then
%               write$(add.period$(pop()))

% The output function calls output.nonnull if its argument is non-empty;
% its argument may be a missing field (thus, not necessarily a string)
%
% output(s) ==
%  BEGIN
%       if not empty$(s) then output.nonnull(s)
%       fi
%  END
%
% The output.check function is the same as the output function except that, if
% necessary, output.check warns the user that the t field shouldn't be empty
% (this is because it probably won't be a good reference without the field;
% the entry functions try to make the formatting look reasonable even when
% such fields are empty).
%
% output.check(s,t) ==
%  BEGIN
%       if empty$(s) then
%           warning$("empty " * t * " in " * cite$)
%       else output.nonnull(s)
%       fi
%  END
%
% The output.bibitem function writes the \bibitem for the current entry
% (the label should already have been set up), and sets up the separator
% state for the output functions.  And, it leaves a string on the stack
% as per the output convention.
%
% output.bibitem ==
%  BEGIN
%       newline$
%       write$("\bibitem[")     % for alphabetic labels,
%       write$(label)           % these three lines

%       write$("\bibitem{")             % this line for numeric labels
%       write$(cite$)
%       write$("}")
%       push "" on stack
%       output.state := before.all
%  END
%
% The fin.entry function finishes off an entry by adding a period to the
% string remaining on the stack.  If the state is still before.all
% then nothing was produced for this entry, so the result will look bad,
% but the user deserves it. (We don't omit the whole entry because the
% entry was cited, and a bibitem is needed to define the citation label.)

% The sortify function converts to lower case after purify$ing; it's
% used in sorting and in computing alphabetic labels after sorting
%
% The chop.word(w,len,s) function returns either s or, if the first len
% letters of s equals w (this comparison is done in the third line of the
% function's definition), it returns that part of s after w.
% This long comment applies only to alphabetic labels
%
% The format.lab.names function makes a short label by using the initials of
% the von and Last parts of the names (but if there are more than four names,
% (i.e., people) it truncates after three and adds a superscripted "+";
% it also adds such a "+" if the last of multiple authors is "others").
% If there is only one name, and its von and Last parts combined have just
% a single name-token ("Knuth" has a single token, "Brinch Hansen" has two),
% we take the first three letters of the last name.  The boolean
% et.al.char.used tells whether we've used a superscripted "+", so that we
% know whether to include a LaTeX macro for it.

%
% Exactly what fields we look at in constructing the primary part of the label
% depends on the entry type; this selectivity (as opposed to, say, always
% looking at author, then editor, then key) helps ensure that "ignored" fields,
% as described in the LaTeX book, really are ignored.  Note that MISC is part
% of the deepest `else' clause in the nested part of calc.label; thus, any
% unrecognized entry type in the database is handled correctly.
%
% There is one auxiliary function for each of the four different sequences of
% fields we use.  The first of these functions looks at the author field, and
% then, if necessary, the key field.  The other three functions, which might
% look at two fields and the key field, are similar, except that the key field
% takes precedence over the organization field (for labels---not for sorting).
%
% The calc.label function calculates the preliminary label of an entry, which
% is formed by taking three letters of information from the author or editor or
% key or organization field (depending on the entry type and on what's empty,
% but ignoring a leading "The " in the organization), and appending the last
% two characters (digits) of the year. It is an error if the appropriate fields
% among author, editor, organization, and key are missing, and we use
% the first three letters of the cite$ in desperation when this happens.
% The resulting label has the year part, but not the name part, purify$ed
% (purify$ing the year allows some sorting shenanigans by the user).
%
% This function also calculates the version of the label to be used in sorting.
%
% The final label may need a trailing 'a', 'b', etc., to distinguish it from
% otherwise identical labels, but we can't calculated those "extra.label"s
% until after sorting.
%

%               % assuming we will also sort, we calculate a sort.label
%       sort.label := sortify(label), but use the last four, not two, digits
%  END
% When sorting, we compute the sortkey by executing "presort" on each entry.
% The presort key contains a number of "sortify"ed strings, concatenated
% with multiple blanks between them.  This makes things like "brinch  per"
% come before "brinch hansen  per".
%
% The fields used here are: the sort.label for alphabetic labels (as set by
% calc.label), followed by the author names (or editor names or organization
% (with a leading "The " removed) or key field, depending on entry type and on
% what's empty), followed by year, followed by the first bit of the title
% (chopping off a leading "The ", "A ", or "An ").
% Names are formatted: Von Last First Junior.
% The names within a part will be separated by a single blank
% (such as "brinch hansen"), two will separate the name parts themselves
% (except the von and last), three will separate the names,
% four will separate the names from year (and from label, if alphabetic),
% and four will separate year from title.
%
% The sort.format.names function takes an argument that should be in
% BibTeX name format, and returns a string containing "   "-separated
% names in the format described above.  The function is almost the same
% as format.names.
% This long comment applies only to alphabetic labels, when sorted
%
% Now comes the final computation for alphabetic labels, putting in the 'a's
% and 'b's and so forth if required.  This involves two passes: a forward
% pass to put in the 'b's, 'c's and so on, and a backwards pass
% to put in the 'a's (we don't want to put in 'a's unless we know there
% are 'b's).
