我正在尝试将网站转换为电子书,并且每个页面的开头都有一大块html我要删除。可以想象,使用Q
导致没有匹配,因为大块中的某些东西没有被正确转义。当我尝试将问题解决时,我得到堆栈溢出。
我真正需要的是以通常的M-%方式在没有正则表达式的dired 中查找和替换的方法。这可能吗?
答案 0 :(得分:6)
正则表达式在理论上是可选的,但该函数在一些地方调用硬编码假设。我认为最简单的解决方案是制作在运行时不设置正则表达式标志的副本。

Fourth arg FILE-LIST-FORM non-nil means initialize the replacement loop.
Fifth and sixth arguments START and END are accepted, for compatibility
with `query-replace', and ignored.
If FILE-LIST-FORM is non-nil, it is a form to evaluate to
produce the list of files to search.
