![获取忽略括号内内容的命令?](https://linux22.com/image/333335/%E8%8E%B7%E5%8F%96%E5%BF%BD%E7%95%A5%E6%8B%AC%E5%8F%B7%E5%86%85%E5%86%85%E5%AE%B9%E7%9A%84%E5%91%BD%E4%BB%A4%EF%BC%9F.png)
更新:@wipet 的回答几乎完美,唯一的问题似乎是它不能正确地与 配合使用safeinputenc
:重音字符不能正确大写,奇怪的命令(例如){\'\i}
会引发各种错误。例如,这不会发生在biblatex
自己的上\MakeSentenceCase
,所以我会把它留在这里,以防有人有任何想法。
另一个更新:\endcsname
如果我在使用@wipet 命令的字段中使用 {\LaTeX},smartuppercase
我会收到“缺少插入”错误。
我正在使用 biblatex 并且我这样做了:
\DeclareFieldFormat{uppercase}{\MakeUppercase{#1}}
所以当我想以大写形式打印字段时,我可以使用\printfield[uppercase]{title}
。
问题是这总是让一切大写,并且我想忽略括号中的内容,这样,例如,{an Introduction to {LaTeX}}
打印为“LaTeX 简介”。我该怎么做?

我的结果:
但应该是“圣保罗”。
编辑:
我不知道这是否有用:biblatex
有一个\MakeSentenceCase
命令可以按照我想要的方式工作,但它只会将句子中的第一个字母大写,其余字母则变为小写。我试图找到它的定义方式,以便也许我可以对大写命令执行类似操作,我认为这是相关的部分,但对我来说毫无意义。我假设mksc
代表“使小写字母”,这就是我所能得到的。

也许你需要这样的东西:
\long\def\addto#1#2{\expandafter\def\expandafter#1\expandafter{#1#2}}
\def\traceparam#1{\def\paramL{}\traceparamA #1\end}
\def\traceparamA{\futurelet\next\traceparamB}
\def\traceparamB{%
\let\nexts=\undefined
\expandafter\ifx\space\next \let\nexts=\traceparamS \fi
\ifx\bgroup\next \let\nexts=\traceparamD \fi
\ifx\end\next \let\nexts=\traceparamE \fi
\ifx\nexts\undefined \let\nexts=\traceparamC\fi
\nexts
}
\def\traceparamS{\addto\paramL{ }\afterassignment\traceparamA \let\next= }
\def\traceparamC#1{\addto\paramL{#1}\traceparamA}
\def\traceparamD#1{%
\expandafter\addto\expandafter\paramL\expandafter{\csname ll:#1\endcsname}%
\expandafter\def\csname ll:#1\endcsname{#1}%
\traceparamA
}
\def\traceparamE\end{}
\def\smartuppercase#1{%
\bgroup
\traceparam{#1}%
\uppercase\expandafter{\paramL}%
\egroup
}
\smartuppercase{an Introduction to {TeX}}
编辑:如果重音字符有问题,那么你可以尝试\uppecase
用\MakeUpercase
这样的方式替换
%\uppercase\expandafter{\paramL}%
\MakeUppercase{\paramL}
并且您必须像这样保护生成的 csnames:
%\expandafter\addto\expandafter\paramL\expandafter{\csname ll:#1\endcsname}%
\expandafter\addto\expandafter\paramL\expandafter
{\expandafter\noexpand\csname ll:#1\endcsname}%
