+%
+%
+% \section{简介}
+%
+% 《GB/T 7714-2015 信息与文献\ 参考文献著录规则》(以下简称《规则》)是我国关于
+% 参考文献的推荐标准。
+% 本宏包是《规则》的 \BibTeX{} 实现,具有以下特性:
+% \begin{itemize}
+% \item 兼容 \pkg{natbib}
+% \item 支持了顺序编码制和著者-出版年制两种风格
+% \item 自动识别语言并进行相应处理
+% \end{itemize}
+%
+%
+% \section{相关工作}
+%
+% TeX 社区一直在努力实现国家的参考文献推荐标准。2005 年
+%
+%
+% \section{使用宏包}
+%
+% 首先应在导言区调用宏包 \pkg{gbt7714} ,可以选择的参数如
+% 表~\ref{tab:options}。
+%
+% \begin{table}[htbp]
+% \centering
+% \begin{tabular}{lll}
+% \toprule
+% 参数 & 参考文献列表 & 引用标注 \\
+% \midrule
+% \opt{super} (默认) & 顺序编码 & 角标数字 \\
+% \opt{numbers} & 顺序编码 & 数字 \\
+% \opt{authoryear} & 著者-出版年 & 著者-出版年 \\
+% \bottomrule
+% \end{tabular}
+% \caption{参考文献风格的参数}
+% \label{tab:options}
+% \end{table}
+%
+% 举个例子:
+% \begin{latex}
+% \usepackage[authoryear]{gbt7714}
+% \end{latex}
+% 然后\emph{不再}需要调用 \cs{bibliographystyle} 命令设置参考文献列表风格。
+%
+% 使用时需要注意以下两点:
+% \begin{itemize}
+% \item 使用的 bib 数据库应使用 UTF-8 编码。
+% \item 使用著者-出版年制参考文献表时,中文文献需要在 key 域填写作者姓名
+% 的拼音,才能使得文献列表按照拼音排序。
+% \end{itemize}
+%
+%
+% \section{文献类型}
+%
+% 《规则》中列举了 16 种参考文献类型,
+% 表~\ref{tab:entry-types} 列举了 \file{bib} 数据库中对应的文献类型。
+% 这些都尽可能地兼容 \BibTeX{} 的标准类型,但是新增了若干文献类型(带星号的)。
+%
+% \begin{table}[htbp]
+% \centering
+% \begin{tabular}{lcl}
+% \toprule
+% 文献类型 & 标识代码 & Entry Type \\
+% \midrule
+% 普通图书 & M & book 或 inbook \\
+% 图书的析出文献 & M & incollection \\
+% 会议录 & C & proceedings \\
+% 会议录的析出文献 & C & inproceedings 或 conference \\
+% 汇编 & G & collection* \\
+% 报纸 & N & newspaper* \\
+% 期刊的析出文献 & J & article \\
+% 学位论文 & D & mastersthesis 或 phdthesis \\
+% 报告 & R & techreport \\
+% 标准 & S & standard* \\
+% 专利 & P & patent* \\
+% 数据库 & DB & database* \\
+% 计算机程序 & CP & software* \\
+% 电子公告 & EB & online* \\
+% 档案 & A & archive* \\
+% 舆图 & CM & map* \\
+% 数据集 & DS & dataset* \\
+% 其他 & Z & misc \\
+% \bottomrule
+% \end{tabular}
+% \caption{全部文献类型,其中带星号的不是 \BibTeX{} 标准类型}
+% \label{tab:entry-types}
+% \end{table}
+%
+% 注意,不支持的 \BibTeX{} 标准类型有 booklet, manual, unpublished。
+%
+%
+% \section{著录项目}
+%
+% 以下列出了本宏包支持的全部著录项目。
+%
+% \begin{table}[htbp]
+% \centering
+% \begin{tabular}{ll}
+% \toprule
+% 著录项目(域) & Field \\
+% \midrule
+% 主要责任者 & author \\
+% 题名 & title \\
+% 文献类型标识 & mark* \\
+% 载体类型标识 & medium* \\
+% 译者 & translator* \\
+% 编辑 & editor \\
+% 组织(用于会议) & organization \\
+% 图书题名 & booktitle \\
+% 系列 & series \\
+% 期刊题名 & journal \\
+% 版本 & edition \\
+% 出版地 & address \\
+% 出版者 & publisher \\
+% 学校(用于phdthesis) & school \\
+% 机构(用于techreport) & institution \\
+% 出版年 & year \\
+% 卷 & volume \\
+% 期(或者专利号) & number \\
+% 引文页码 & pages \\
+% 更新或修改日期 & date* \\
+% 引用日期 & urldate* \\
+% 获取和访问路径 & url \\
+% 数字对象唯一标识符 & doi \\
+% 拼音(用于排序) & key \\
+% 语言 & language* \\
+% \bottomrule
+% \end{tabular}
+% \caption{全部著录项目,其中带星号的不是 \BibTeX{}/natbib 的标准著录项目。}
+% \label{tab:fields}
+% \end{table}
+%
+% 由于《规则》中要的著录项目比 \BibTeX{} 支持的要多,新增的项目尽可能同
+% BibLaTeX 一致,如 date 和 urldate。
+%
+% 本宏包默认情况下可以自动识别文献语言,并自动处理文献类型和载体类型标识,
+% 但是在少数情况下需要用户手动指定,如:
+% \begin{latex}
+% @article{citekey,
+% language = {japanese},
+% mark = {M},
+% medium = {CD},
+% ...
+% \end{latex}
+% 可选的语言有 english, chinese, japanese, russian,
+% 目前对日语和俄语的支持较为有限。
+%
+% \section{参考文献列表的排序}
+%
+% 在使用著者-出版年制时,需要将中文参考文献按照拼音或者笔画排序,然而 Unicode
+% 中汉字是根据康熙字典排序的,而且由于 \BibTeX{} 功能的局限性,我们无法根据著
+% 者姓名读取拼音,所以只能手动处理:在 key 域手动添加著者姓名拼音,
+% 如:
+% \begin{latex}
+% @book{capital,
+% author = {马克思 and 恩格斯},
+% key = {ma3 ke4 si1 en1 ge2 si1},
+% ...
+% \end{latex}
+%
+% \StopEventually{}

+ booktitle
+ date
+ doi
+ edition

+ pages
+ publisher
+ school
+ series
+ title
+ translator
+ url
+ urldate
+ volume
+ year
+ }
+ { entry.lang }
+% \end{macrocode}
+%
+% These string entry variables are used to form the citation label.
+% In a storage pinch, sort.label can be easily computed on the fly.
+%
+% \begin{macrocode}
+ { label extra.label sort.label short.list entry.mark }
+
+% \end{macrocode}
+%
+% \subsection{Entry functions}
+% 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.
+%
+% 由于专著中的析出文献需要用到很特殊的“//”,所以我又加了一个 after.slash。
+% 其他需要在特定符号后面输出,所以写了一个 output.after。
+%
+% \begin{pseudocode}
+% 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$(pop()))
+% newline$
+% write$("\newblock ")
+% else
+% if output.state = before.all then
+% write$(pop())
+% else -- output.state should be after.sentence
+% write$(add.period$(pop()) * " ")
+% fi
+% fi
+% output.state := mid.sentence
+% fi
+% push s on stack
+% END
+% \end{pseudocode}
+%
+% The output function calls output.nonnull if its argument is non-empty;
+% its argument may be a missing field (thus, not necessarily a string)
+%
+% \begin{pseudocode}
+% output(s) ==
+% BEGIN
+% if not empty$(s) then output.nonnull(s)
+% fi
+% END
+% \end{pseudocode}
+%
+% The output.check function is the same as the output function except that, if
+% necessary, output.check warns the user that the t field shouldn't be empty
+% (this is because it probably won't be a good reference without the field;
+% the entry functions try to make the formatting look reasonable even when
+% such fields are empty).
+%
+% \begin{pseudocode}
+% output.check(s,t) ==
+% BEGIN
+% if empty$(s) then
+% warning$("empty " * t * " in " * cite$)
+% else output.nonnull(s)
+% fi
+% END
+% \end{pseudocode}
+%
+% 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.
+%
+% \begin{pseudocode}
+% output.bibitem ==
+% BEGIN
+% newline$
+% write$("\bibitem[") % for alphabetic labels,
+% write$(label) % these three lines
+% write$("]{") % are used
+% write$("\bibitem{") % this line for numeric labels
+% write$(cite$)
+% write$("}")
+% push "" on stack
+% output.state := before.all
+% END
+% \end{pseudocode}
+%
+% The fin.entry function finishes off an entry by adding a period to the
+% string remaining on the stack. If the state is still before.all
+% then nothing was produced for this entry, so the result will look bad,
+% but the user deserves it. (We don't omit the whole entry because the
+% entry was cited, and a bibitem is needed to define the citation label.)
+%
+% \begin{pseudocode}
+% fin.entry ==
+% BEGIN
+% write$(add.period$(pop()))
+% newline$
+% END
+% \end{pseudocode}
+%
+% The new.block function prepares for a new block to be output, and
+% new.sentence prepares for a new sentence.
+%
+% \begin{pseudocode}
+% new.block ==
+% BEGIN
+% if output.state <> before.all then
+% output.state := after.block
+% fi
+% END
+% \end{pseudocode}
+%
+% \begin{pseudocode}
+% new.sentence ==
+% BEGIN
+% if output.state <> after.block then
+% if output.state <> before.all then
+% output.state := after.sentence
+% fi
+% fi

+% \subsection{Formatting chunks}
+% Here are some functions for formatting chunks of an entry.
+% By convention they either produce a string that can be followed by
+% a comma or period (using |add.period$|, so it is OK to end in a period),
+% or they produce the null string.
+%
+% A useful utility is the field.or.null function, which checks if the
+% argument is the result of pushing a `missing' field (one for which no
+% assignment was made when the current entry was read in from the database)
+% or the result of pushing a string having no non-white-space characters.
+% It returns the null string if so, otherwise it returns the field string.
+% Its main (but not only) purpose is to guarantee that what's left on the
+% stack is a string rather than a missing field.
+%
+% \begin{pseudocode}
+% field.or.null(s) ==
+% BEGIN
+% if empty$(s) then return ""
+% else return s
+% END
+% \end{pseudocode}
+%
+% Another helper function is emphasize, which returns the argument emphazised,
+% if that is non-empty, otherwise it returns the null string. Italic
+% corrections aren't used, so this function should be used when punctation
+% will follow the result.
+%
+% \begin{pseudocode}
+% emphasize(s) ==
+% BEGIN
+% if empty$(s) then return ""
+% else return "{\em " * s * "}"
+% \begin{pseudocode}
+%
+% The format.names function formats the argument (which should be in
+% BibTeX name format) into "First Von Last, Junior", separated by commas
+% and with an "and" before the last (but ending with "et~al." if the last
+% of multiple authors is "others"). This function's argument should always
+% contain at least one name.
+%
+% VAR: nameptr, namesleft, numnames: INTEGER
+% pseudoVAR: nameresult: STRING (it's what's accumulated on the stack)
+%
+% \begin{pseudocode}
+% format.names(s) ==
+% BEGIN
+% nameptr := 1
+% numnames := num.names$(s)
+% namesleft := numnames
+% while namesleft > 0
+% do
+% % for full names:
+% t := format.name$(s, nameptr, "{ff~}{vv~}{ll}{, jj}")
+% % for abbreviated first names:
+% t := format.name$(s, nameptr, "{f.~}{vv~}{ll}{, jj}")
+% if nameptr > 1 then
+% if namesleft > 1 then nameresult := nameresult * ", " * t
+% else if numnames > 2
+% then nameresult := nameresult * ","
+% fi
+% if t = "others"
+% then nameresult := nameresult * " et~al."
+% else nameresult := nameresult * " and " * t
+% fi
+% fi
+% else nameresult := t
+% fi
+% nameptr := nameptr + 1
+% namesleft := namesleft - 1
+% od
+% return nameresult
+% END
+% \end{pseudocode}
+%
+% The format.authors function returns the result of format.names(author)
+% if the author is present, or else it returns the null string
+%
+% \begin{pseudocode}
+% format.authors ==
+% BEGIN
+% if empty$(author) then return ""
+% else return format.names(author)
+% fi
+% END
+% \end{pseudocode}
+%
+% Format.editors is like format.authors, but it uses the editor field,
+% and appends ", editor" or ", editors"
+%
+% \begin{pseudocode}
+% format.editors ==
+% BEGIN
+% if empty$(editor) then return ""
+% else
+% if num.names$(editor) > 1 then
+% return format.names(editor) * ", editors"
+% else
+% return format.names(editor) * ", editor"
+% fi
+% fi
+% END
+% \end{pseudocode}
+%
+% Other formatting functions are similar, so no "comment version" will be
+% given for them.
+%
+% The `pop\$' in this function gets rid of the duplicate `empty' value and
+% the `skip\$' returns the duplicate field value

+% the series field unchanged if it exists or else the null string.
+% If both the number and series fields are there we assume the series field
+% gives the name of the whole series (the title field should be the title
+% of the work being one referred to), and we add an "in <series>".

+%
+% Now come the cross-referencing functions (these are invoked because
+% one entry in the database file(s) cross-references another, by giving
+% the other entry's database key in a `crossref' field). This feature
+% allows one or more titled things that are part of a larger titled
+% thing to cross-reference the larger thing. These styles allow for
+% five posibilities: (1) an ARTICLE may cross-reference an ARTICLE;
+% (2) a BOOK, (3) INBOOK, or (4) INCOLLECTION may cross-reference a BOOK;
+% or (5) an INPROCEEDINGS may cross-reference a PROCEEDINGS.
+% Each of these is explained in more detail later.
+%
+% An ARTICLE entry type may cross reference another ARTICLE (this is
+% intended for when an entire journal is devoted to a single topic---
+% but since there is no JOURNAL entry type, the journal, too, should be
+% classified as an ARTICLE but without the author and title fields).
+% This will result in two warning messages for the journal's entry
+% if it's included in the reference list, but such is life.
+%
+% format.article.crossref ==
+% BEGIN
+% if empty$(key) then
+% if empty$(journal) then
+% warning$("need key or journal for " * cite$ *
+% " to crossref " * crossref)
+% return(" \cite{" * crossref * "}")
+% else
+% return("In " * emphazise.correct (journal) *
+% " \cite{" * crossref * "}")
+% fi
+% else
+% return("In " * key * " \cite{" * crossref * "}")
+% fi
+% END
+%
+% The other cross-referencing functions are similar, so no "comment version"
+% will be given for them.
+%
+% \begin{macrocode}
+FUNCTION {format.article.crossref}
+{ key empty$
+ { journal empty$
+ { "need key or journal for " cite$ * " to crossref " * crossref *
+ warning$

+ if$
+ }
+ { "In " }
+ if$
+ " \citet{" * crossref * "}" *
+}
+
+% \end{macrocode}
+%
+% A BOOK (or INBOOK) entry type (assumed to be for a single volume in a
+% multivolume work) may cross reference another BOOK (the entire multivolume).
+% Usually there will be an editor, in which case we use that to construct the
+% cross reference; otherwise we use a nonempty key field or else the series
+% field (since the series gives the title of the multivolume work).
+%
+% \begin{macrocode}
+FUNCTION {format.book.crossref}
+{ volume empty$
+ { "empty volume in " cite$ * "'s crossref of " * crossref * warning$
+ "In "
+ }

+
+% \end{macrocode}
+%
+% An INCOLLECTION entry type may cross reference a BOOK (assumed to be the
+% collection), or an INPROCEEDINGS may cross reference a PROCEEDINGS.
+% Often there will be an editor, in which case we use that to construct
+% the cross reference; otherwise we use a nonempty key field or else
+% the booktitle field (which gives the cross-referenced work's title).
+%
+% \begin{macrocode}
+FUNCTION {format.incoll.inproc.crossref}
+{ editor empty$
+ editor field.or.null author field.or.null =

+%
+% \subsection{Functions for all entry types}
+%
+% Now we define the type functions for all entry types that may appear
+% in the .BIB file---e.g., functions like `article' and `book'. These
+% are the routines that actually generate the .BBL-file output for
+% the entry. These must all precede the READ command. In addition, the
+% style designer should have a function `default.type' for unknown types.
+% Note: The fields (within each list) are listed in order of appearance,
+% except as described for an `inbook' or a `proceedings'.
+%
+% The article function is for an article in a journal. An article may
+% CROSSREF another article.
+% Required fields: author, title, journal, year
+% Optional fields: volume, number, pages, month, note
+%
+% \begin{pseudocode}
+% article ==
+% BEGIN
+% output.bibitem
+% output.check(format.authors,"author")
+% new.block
+% output.check(format.title,"title")
+% new.block
+% if missing$(crossref) then
+% output.check(emphasize(journal),"journal")
+% output(format.vol.num.pages)
+% output.check(format.date,"year")
+% else
+% output.nonnull(format.article.crossref)
+% output(format.pages)
+% fi
+% new.block
+% output(note)
+% fin.entry
+% END
+% \end{pseudocode}
+%
+% The book function is for a whole book. A book may CROSSREF another book.
+% Required fields: author or editor, title, publisher, year
+% Optional fields: volume or number, series, address, edition, month,
+% note
+%
+% \begin{pseudocode}
+% book ==
+% BEGIN
+% if empty$(author) then output.check(format.editors,"author and editor")
+% else output.check(format.authors,"author")
+% if missing$(crossref) then
+% either.or.check("author and editor",editor)
+% fi
+% fi
+% new.block
+% output.check(format.btitle,"title")
+% if missing$(crossref) then
+% output(format.bvolume)
+% new.block
+% output(format.number.series)
+% new.sentence
+% output.check(publisher,"publisher")
+% output(address)
+% else
+% new.block
+% output.nonnull(format.book.crossref)
+% fi
+% output(format.edition)
+% output.check(format.date,"year")
+% new.block
+% output(note)
+% fin.entry
+% END
+% \end{pseudocode}
+%
+% The other entry functions are all quite similar, so no "comment version"
+% will be given for them.

+% 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.
