在代码列表中创建超链接

Question

我正在尝试实现一些我认为是基本功能的东西。只是一个出现位置的超链接（在代码列表中）。如果读者可以点击链接就更好了。但它会返回一条错误消息，并造成痛苦的混乱。

\begin{lstlisting}[language=bash, breaklines,escapechar=|]
$ wget https://launchpad.net/ubuntu/+archive/primary/+sourcefiles/tcc/0.9.27+git20200814.62c30a4a-1/tcc_0.9.27+git20200814.62c30a4a.orig.tar.bz2

$ wget |\href{http://foo.com/MyFunctionDocs.html}{MyFunction}|(x);

$ wget |\href{http://foo.com/MyFunctionDocs.html}{https://launchpad.net/ubuntu/+archive/primary/+sourcefiles/tcc/0.9.27+git20200814.62c30a4a-1/tcc_0.9.27+git20200814.62c30a4a.orig.tar.bz2}|(x);

$ tar -xvjf tcc_0.9.27+git20200814.62c30a4a.orig.tar.bz2
$ gcc --version
gcc (Ubuntu 11.2.0-19ubuntu1) 11.2.0
$ ./configure --cc=gcc
$ make
$ make install
\end{lstlisting}

它看起来如何（没有超链接）。

该错误消息似乎与我尝试执行的操作几乎没有任何关系。

Missing $ inserted.

You need to enclose all mathematical expressions and symbols with special markers. These special markers create a ‘math mode’.

Use $...$ for inline math mode, and \[...\]or one of the mathematical environments (e.g. equation) for display math mode.

This applies to symbols such as subscripts ( _ ), integrals ( \int ), Greek letters ( \alpha, \beta, \delta ) and modifiers (\vec{x}, \tilde{x}).

my insertion and my current dilemma will both disappear.

排版有问题。这似乎是因为 TeX 试图变得聪明，强迫我进入数学模式，而这与我正在做的事情无关。我使用的“解决方案”来自代码清单中的内联链接

随后的尝试也因字体损坏而失败。

$ wget |\href{http://foo.com/MyFunctionDocs.html}{https://launchpad.net/ubuntu/+archive}|

$ wget |\url{https://launchpad.net/ubuntu/+archive/primary/+sourcefiles/tcc/0.9.27+git20200814.62c30a4a-1/tcc_0.9.27+git20200814.62c30a4a.orig.tar.bz2}|;

下面是一个最小的不起作用的示例。很容易看出什么都不起作用。在创建超链接等简单功能的所有尝试中，渲染都失败了。

Answer 1

由于文本中的下划线，您会收到错误。下划线仅在数学模式下允许，因此 TeX 会切换到该模式。要么将下划线转义为\_，要么使用\nolinkurl或\url（最后一个自然会产生不同的链接）。

\documentclass{article}
\usepackage{listings}
\usepackage{hyperref}
\begin{document}
\begin{lstlisting}[language=bash, breaklines,escapechar=|]
$ wget |\href{http://foo.com/MyFunctionDocs.html}{https://...tcc\_0.9.27}|(x);

$ wget |\href{http://foo.com/MyFunctionDocs.html}{\nolinkurl{https://...tcc_0.9.27}}|(x);

$ wget |\url{https://...tcc_0.9.27}|(x)
\end{lstlisting}
\end{document}

Answer 2

我适应了链接问题中的第二个答案有点。这样字体就正确了。

%! TEX program = lualatex

\documentclass{article}
\usepackage{listings}
\usepackage[margin=1cm]{geometry}
\usepackage{hyperref}
