在构建时，我看到许多警告，例如Overfull \hbox (42.20813pt too wide) in paragraph at lines 20--21
结果屏幕截图如下所示。
我已经使用了该breaklines=true选项，但我不知道如何正确包装长源代码。
答案1
这是由于 的缺点listings，导致它无法破坏长序列的数字和其他符号字符（即使breaklines设置并breakatwhitespace清除了）。
这里，一个临时的 hack 是添加
literate={:}{:}{1},
在传递给的键值对列表中，\lstset以便用长度为的:文字冒号替换源中的任何冒号；这将允许任何冒号后出现换行符，因为它不再被视为“正常”的序列符号。:1
