全局子匹配（）？
我想找到一行，然后匹配该行中的几个单词，但我不想替换它们，而是更愿意简单地保存它们（通过附加到寄存器或导出到文件）。
在这方面，反向引用（即 submatch(1) 或 \1）是否可行，或者只能通过替换？我意识到我可以替换回我正在处理的文件 - 更改它 - 但我更愿意导出它。
有没有办法在替换中调用函数（以保存子匹配）而不损坏文件？或者，最好使用全局搜索来捕获该行的一部分，然后将其作为参数传递给函数调用，该函数调用将根据需要进行保存？
I wanted to find a line, then match several words within that line BUT instead of substituting them I would prefer to simply save them (by appending to a register, or exporting to a file).
Is back-referencing (i.e. submatch(1) or \1) doable in this regards, or is that only through the substitution? I realize I could substitute back to the file I am working on - altering it - but I would prefer to export it.
Is there a way to call a function (to save the submatch) within substitute without damaging the file? Or, preferably, use the global search to capture a portion of the line and then pass that as a parameter onto a function call that would do the saving as desired?

尝试
或
。在最后一种情况下，SaverFunc 必须返回字符串或数字（如果没有显式
:return语句，它将返回数字 0）。返回哪个字符串或数字并不重要：string_or_number[-1]始终扩展为空字符串。Try
or
. In last case SaverFunc must return either string or number (without explicit
:returnstatement it will return number 0). It does not matter which string or number will be returned:string_or_number[-1]always expands to an empty string.您可能正在寻找
:h :global并执行如下操作：这将在与给定模式匹配的每一行上调用该函数。
You might be looking for
:h :globaland do something like this:That would call the function on every line matching the given pattern.
