60 % 1.10 (2002/09/27) Initial release
63 % 1. Fixed bug with URLs containing underscores when using url.sty. Thanks
64 % to Ming Kin Lai for reporting this.
67 % 1. Fixed bug with unwanted comma before "et al." when an entry contained
68 % more than two author names. Thanks to Pallav Gupta for reporting this.
69 % 2. Fixed bug with anomalous closing quote in tech reports that have a
70 % type, but without a number or address. Thanks to Mehrdad Mirreza for
72 % 3. Use braces in \providecommand in begin.bib to better support
73 % latex2html. TeX style length assignments OK with recent versions
74 % of latex2html - 1.71 (2002/2/1) or later is strongly recommended.
75 % Use of the language field still causes trouble with latex2html.
76 % Thanks to Federico Beffa for reporting this.
77 % 4. Added IEEEtran.bst ID and version comment string to .bbl output.
78 % 5. Provide a \BIBdecl hook that allows the user to execute commands
79 % just prior to the first entry.
80 % 6. Use default urlstyle (is using url.sty) of "same" rather than rm to
81 % better work with a wider variety of bibliography styles.
82 % 7. Changed month abbreviations from Sept., July and June to Sep., Jul.,
83 % and Jun., respectively, as IEEE now does. Thanks to Moritz Borgmann
85 % 8. Control entry types should not be considered when calculating longest
87 % 9. Added alias www for electronic/online.
88 % 10. Added CTLname_url_prefix control entry type.

92 %% DEFAULTS FOR THE CONTROLS OF THE BST STYLE %%
93 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
95 % These are the defaults for the user adjustable controls. The values used
96 % here can be overridden by the user via IEEEtranBSTCTL entry type.
98 % NOTE: The recommended LaTeX command to invoke a control entry type is:
101 %\def\bstctlcite{\@ifnextchar[{\@bstctlcite}{\@bstctlcite[@auxout]}}
102 %\def\@bstctlcite[#1]#2{\@bsphack
103 % \@for\@citeb:=#2\do{%
104 % \edef\@citeb{\expandafter\@firstofone\@citeb}%
105 % \if@filesw\immediate\write\csname #1\endcsname{\string\citation{\@citeb}}\fi}%
109 % It is called at the start of the document, before the first \cite, like:
110 % \bstctlcite{IEEEexample:BSTcontrol}
112 % IEEEtran.cls V1.6 and later does provide this command.
116 % #0 turns off the display of the number for articles.
118 FUNCTION {default.is.use.number.for.article} { #1 }
121 % #0 turns off the display of the paper and type fields in @inproceedings.
123 FUNCTION {default.is.use.paper} { #1 }
126 % #0 turns off the forced use of "et al."
128 FUNCTION {default.is.forced.et.al} { #0 }
130 % The maximum number of names that can be present beyond which an "et al."
131 % usage is forced. Be sure that num.names.shown.with.forced.et.al (below)
132 % is not greater than this value!
133 % Note: There are many instances of references in IEEE journals which have
134 % a very large number of authors as well as instances in which "et al." is
136 FUNCTION {default.max.num.names.before.forced.et.al} { #10 }
138 % The number of names that will be shown with a forced "et al.".
139 % Must be less than or equal to max.num.names.before.forced.et.al
140 FUNCTION {default.num.names.shown.with.forced.et.al} { #1 }
143 % #0 turns off the alternate interword spacing for entries with URLs.
145 FUNCTION {default.is.use.alt.interword.spacing} { #1 }
147 % If alternate interword spacing for entries with URLs is enabled, this is
148 % the interword spacing stretch factor that will be used. For example, the
149 % default "4" here means that the interword spacing in entries with URLs can
150 % stretch to four times normal. Does not have to be an integer. Note that
151 % the value specified here can be overridden by the user in their LaTeX
152 % code via a command such as:
153 % "\providecommand\BIBentryALTinterwordstretchfactor{1.5}" in addition to
154 % that via the IEEEtranBSTCTL entry type.
155 FUNCTION {default.ALTinterwordstretchfactor} { "4" }
158 % #0 turns off the "dashification" of repeated (i.e., identical to those
159 % of the previous entry) names. IEEE normally does this.
161 FUNCTION {default.is.dash.repeated.names} { #1 }
164 % The default name format control string.
165 FUNCTION {default.name.format.string}{ "{f.~}{vv~}{ll}{, jj}" }
168 % The default LaTeX font command for the names.
169 FUNCTION {default.name.latex.cmd}{ "" }
172 % The default URL prefix.
173 FUNCTION {default.name.url.prefix}{ "[Online]. Available:" }
176 % Other controls that cannot be accessed via IEEEtranBSTCTL entry type.

179 % operate more quietly.

406 % This IEEEtran.bst features a very powerful and flexible mechanism for
407 % controlling the capitalization, punctuation, spacing, quotation, and
408 % newlines of the formatted entry fields. (Note: IEEEtran.bst does not need
409 % or use the newline/newblock feature, but it has been implemented for
410 % possible future use.) The output states of IEEEtran.bst consist of
411 % multiple independent attributes and, as such, can be thought of as being
412 % vectors, rather than the simple scalar values ("before.all",
413 % "mid.sentence", etc.) used in most other .bst files.
415 % The more flexible and complex design used here was motivated in part by
416 % IEEE's rather unusual bibliography style. For example, IEEE ends the
417 % previous field item with a period and large space prior to the publisher
418 % address; the @electronic entry types use periods as inter-item punctuation
419 % rather than the commas used by the other entry types; and URLs are never
420 % followed by periods even though they are the last item in the entry.
421 % Although it is possible to accommodate these features with the conventional
422 % output state system, the seemingly endless exceptions make for convoluted,
423 % unreliable and difficult to maintain code.
425 % IEEEtran.bst's output state system can be easily understood via a simple
426 % illustration of two most recently formatted entry fields (on the stack):
431 % which, in this example, is to eventually appear in the bibliography as:
433 % "PREVIOUS_ITEM," CURRENT_ITEM
435 % It is the job of the output routine to take the previous item off of the
436 % stack (while leaving the current item at the top of the stack), apply its
437 % trailing punctuation (including closing quote marks) and spacing, and then
438 % to write the result to BibTeX's output buffer:
442 % Punctuation (and spacing) between items is often determined by both of the
443 % items rather than just the first one. The presence of quotation marks
444 % further complicates the situation because, in standard English, trailing
445 % punctuation marks are supposed to be contained within the quotes.
447 % IEEEtran.bst maintains two output state (aka "status") vectors which
448 % correspond to the previous and current (aka "this") items. Each vector
449 % consists of several independent attributes which track punctuation,
450 % spacing, quotation, and newlines. Capitalization status is handled by a
451 % separate scalar because the format routines, not the output routine,
452 % handle capitalization and, therefore, there is no need to maintain the
453 % capitalization attribute for both the "previous" and "this" items.
455 % When a format routine adds a new item, it copies the current output status
456 % vector to the previous output status vector and (usually) resets the
457 % current (this) output status vector to a "standard status" vector. Using a
458 % "standard status" vector in this way allows us to redefine what we mean by
459 % "standard status" at the start of each entry handler and reuse the same
460 % format routines under the various inter-item separation schemes. For
461 % example, the standard status vector for the @book entry type may use
462 % commas for item separators, while the @electronic type may use periods,
463 % yet both entry handlers exploit many of the exact same format routines.
465 % Because format routines have write access to the output status vector of
466 % the previous item, they can override the punctuation choices of the
467 % previous format routine! Therefore, it becomes trivial to implement rules
468 % such as "Always use a period and a large space before the publisher." By
469 % pushing the generation of the closing quote mark to the output routine, we
470 % avoid all the problems caused by having to close a quote before having all
471 % the information required to determine what the punctuation should be.
473 % The IEEEtran.bst output state system can easily be expanded if needed.
474 % For instance, it is easy to add a "space.tie" attribute value if the
475 % bibliography rules mandate that two items have to be joined with an
