![使用 lstinputlisting 与 tex4ht 会隐藏标题中的所有 ASCII 字符吗?](https://linux22.com/image/467238/%E4%BD%BF%E7%94%A8%20lstinputlisting%20%E4%B8%8E%20tex4ht%20%E4%BC%9A%E9%9A%90%E8%97%8F%E6%A0%87%E9%A2%98%E4%B8%AD%E7%9A%84%E6%89%80%E6%9C%89%20ASCII%20%E5%AD%97%E7%AC%A6%E5%90%97%EF%BC%9F.png)
我正在使用 tex4ht 将我的 LaTex 源构建为 EPUB。目前我遇到了问题lstinputlisting
,字幕(越南语)无法正确显示。
\lstinputlisting[float,language=C++,caption={Một chú thích viết bằng tiếng Việt.}]{data.cpp}
我检查了 tex4ht 生成的中间 XHTML 文件,似乎标题中的每个 ASCII 字符都被删除了,只留下越南语字符。最后一个可见的非 ASCII 字符被“悬空”到下一个范围:
... [redacted]
<body>
<!-- l. 8 --><p>Đạ ộúíếằế</p><pre class='lstinputlisting' id='listing-1'><span class='label'><a id='x1-4r1'></a><span class='ec-lmr-7'>ệ</span></span><span style='color:#000000'><span class='ec-lmtti-10x-x-90'>//</span></span><span style='color:#000000'> <span class='ec-lmtti-10x-x-90'>file.cpp</span>
... [redacted]
...这样整个标题“ĐoAn 代码 1: Mộ頁面ú日我第六章ế结核A還是ế吴维ệt.”被剥离为“Đạ ộúíếằế”和“ệ”(悬垂字符)。
令我惊讶的是,如果我使用该lstlisting
环境,tex4ht 似乎不会对越南语字幕产生任何问题。但是,我不能将此用作解决方法,因为我的项目将包含大量独立代码文件。
你知道为什么会发生这种情况吗?我附上了一份最小可重复示例演示我当前的项目(由于我使用的是 Windows 机器,因此构建脚本是用批处理脚本编写的)。
先感谢您!
答案1
TeX4ht 使用一些特殊指令来抑制 中的不需要的字符\lstinputlisting
。否则,一些不需要的代码将被插入到 HTML 输出中。不幸的是,标题也被抑制了。我们需要在这里关闭字符抑制。可以使用此版本的 来完成listings.4ht

\b:lstinputlisting%
\endgroup}
\HLet\lst@InputListing\:tempa
这是的代码\lstinputlisting
,我们使用这些特殊功能在标题中启用文本:
\pend:def\cptA:{\ht:special{t4ht@]}}
\append:def\cptD:{\ht:special{t4ht@[}}
以下是 MWE:
\documentclass[10pt,a4paper]{book}
% \usepackage{mystyle}
\usepackage{listings}
\usepackage{caption}
\usepackage{listingsutf8}
\renewcommand{\lstlistingname}{Đoạn code}
\usepackage[vietnamese]{babel}
\lstdefinestyle{customstyle}
{
basicstyle=\small\ttfamily,
breaklines=true,
showspaces=false,
showtabs=false,
tabsize=2,
showstringspaces=false,
breakatwhitespace=true,
escapeinside={(*@}{@*)},
numbers=left,
numberstyle=\scriptsize,
stepnumber=1,
numbersep=8pt,
inputencoding=utf8,
extendedchars=true,
}
\lstset{language=C++, style=customstyle}
\begin{document}
%%%% NB: This doesn't show the caption correctly, ASCII characters are omitted
\lstinputlisting[float,language=C++,caption={Một chú thích viết bằng tiếng Việt.}]{data.cpp}
%%%% NB: This, surprisingly, show the caption correctly
\begin{lstlisting}[language=C++,caption={Một chú thích viết bằng tiếng Việt.}]
int main() { return 0; }
\end{lstlisting}
\end{document}
它包括文件data.cpp
:
// file.cpp
int gInitialised = 1234;
float gUninitialised;
const bool gIsFinal = false;
结果如下:
