如何替换 vi 中的匹配分隔符？
我有一些匹配分隔符的文本（在本例中是花括号，文本恰好是 LaTeX，这只是偶然的）：
\nb{\vec{n},\vec{y}} \in \vec{z}
我想做的是全局替换 \nb{...} 与 (...)，同时尊重分隔符的嵌套。即，结果应该是
(\vec{n},\vec{y}) \in \vec{z}
，而不是
(\vec{n},\vec{y}} \in \vec{z)
:%s/\\nb{\(.*\)}/(\1)/g 产生的结果。标准正则表达式无法处理匹配的分隔符，所以我没想到这种方式会起作用。我可以使用一些特定于 vi 的技巧来做到这一点吗？
I have some text which has matched delimiters (in this case, curly braces, and the text happens to be LaTeX, which is only incidental):
\nb{\vec{n},\vec{y}} \in \vec{z}
What I'd like to do is globally replace \nb{...} with (...), while respecting the nesting of delimiters. I.e., the result should be
(\vec{n},\vec{y}) \in \vec{z}
and not
(\vec{n},\vec{y}} \in \vec{z)
which is what would be produced by :%s/\\nb{\(.*\)}/(\1)/g. Standard regular expressions can't handle matched delimiters, so I wasn't expecting this way to work. Is there some vi-specific trick I can use to do this?

如果您安装了 surround.vim 那么以下应该可以解决问题
如果您没有：
概述
创建搜索
\nb{的递归宏，将光标定位在{内，将}{替换为( ）的。细节的荣耀
:set nowrapscan这可以防止搜索在文件周围循环。:let @q="..."将我们的宏存储在q寄存器中/\m\nb{/e+1搜索\nb{并将光标定位在{cs{)之后，环绕版本只会更改周围的{with)@q再次运行宏"因此必须转义一些内容，以便它们正常工作。gg@q转到文件顶部并执行寄存器q中的宏非环绕版本此处略有不同
yi{复制{的"_ca{()更改文本内部并包括{并替换为()"0P将我们刚刚复制的内容粘贴到()中If you have surround.vim installed then the following should do the trick
If you do not:

:set nowrapscanthis prevents searches from looping back around the file.:let @q="..."store our macro inside theqregister/\m\nb{/e+1searches for\nb{and positions the cursor after the{cs{)the surround version will just change the surrounding{with)@qrun the macro again"so must escape a few things so they work correctly.gg@qgo to the top of the file and execute the macro in registerqThe non surround version varies a bit here
