%% gb7714-SEU.bbx --- A bibliography style for SEUthesis template
%% ---------------------------------------------------------------
%%
%%用法：类似于标准的样式在biblatex加载时设置样式
%%文献表正常处理，标注命令主要用cite和parencite
\ProvidesFile{gb7714-SEU.bbx}
  [2022/03/10 v0.1 a biblatex bibliography style for SEUthesis]


%==================================================
%加载gb样式
%==================================================
\RequireBibliographyStyle{gb7714-2015}


%==================================================
%选项设置
%==================================================
\ExecuteBibliographyOptions{

    mathesiscn={[硕士学位论文]},

    in={In:\addthinspace},
    incn={见:\addthinspace},
}


%==================================================
%设置一些标点格式为中文的标点
%==================================================
\renewcommand*{\bibpagespunct}{%
\ifentrytype{article}{\addcolon\addthinspace}{\adddot\addthinspace}%
}%


%==================================================
%调整部分域的输出格式
%==================================================

\DeclareFieldFormat%将thesis的标题格式重设
  [thesis]
  {title}{#1}%\mkbibquote{#1\isdot}

%
%   url和url日期格式
%
\renewbibmacro*{url+urldate}{%
  \usebibmacro{url}%%更换url的位置，放到下面
  \iffieldundef{urlyear}%
    {}{%\setunit*{\addspace}%
    \usebibmacro{urldate}}%
     \setunit{\addperiod\addspace}%
     }
    \renewbibmacro*{urldate}{%
    \setunit{\addcomma\addthinspace}\printtext{\printurldate}}%能用高层命令+选项尽量用命令(比如这里的\printurldate)，而不用\blx@edtfdate这种更底层的命令


%
%   修改作者数量超过限定值，做省略时的处理格式
%   v1.0,20160701,hzz
%   v1.0O,20190103,hzz,修改利用新定义的一个分隔符strandothersdelim
%
%   原理方法:判断作者或译者是否中文，若中文用字符等，否则用et al. 。
\renewbibmacro*{name:andothers}{%
  \ifboolexpr{
    test {\ifnumequal{\value{listcount}}{\value{liststop}}}
    and
    test \ifmorenames
  }{\ifnumgreater{\value{liststop}}{1}%
       {\finalandcomma}%
       {}%biblatex作者要区别单作者加等的情况，这里为符合gbt7714-2015第7.2节的要求加上了逗号。
%\printdelim{andothersdelim}
\printdelim{strandothersdelim}%
}{%当是译者的时候需要特殊处理：从7.2节看等/译前面加逗号，但从示例看等和译同时出现时，译前的逗号没有，比如：
%袁训来, 陈哲, 肖书海, 等.
%胡泳, 范海燕, 译.
%潘惠霞, 魏婧, 杨艳, 等译.
%\ifcurrentname{translator}{\addcomma}{}%
}}

%
%   修改省略作者后的本地化字符串，比如et al.
%   v1.0o,20190103,hzz
%
%   原理方法:默认情况下判断作者或译者是否中文，若中文用字符andotherscn=“等”，否则用andothers=“et al.”。
%   非默认情况，根据选项信息，选择选择强制中文或英文
%   首先设置全局的，然后设置文献表中的，这一等价于将所有的cite命令环境都设置过了
%   而不用对每一个引用命令单独设置，比如cite，parancite，textcite都设置
\DeclareDelimFormat{strandothersdelim}{%
  \ifnumgreater{\value{liststop}}{2}{\finalandcomma}{}%
