regex - 在使用 VIM 进行搜索和替换时，如何保留分组文本并在替换部分中重用它？

Question

在 VIM( 编辑 MacVim 快照 64)中，我正在寻找一种方法来转换这些文本行

can_check_steps = 1
can_edit_work_type = 1
can_edit_vendor = 1
can_edit_place = 1

到

'can_check_steps': can_check_steps,
'can_edit_work_type': can_edit_work_type,
'can_edit_vendor': can_edit_vendor,
'can_edit_place': can_edit_place,

我知道如何添加前导单引号并转换 =进入 :分别使用多行字符替换(我从 this question 学到的东西)和基本搜索和替换。

但我真的不知道如何在每行重复变量名。我也开始认为应该有一种方法可以使用类似的分组表达式(使用 ( 和 ) 在正则表达式中“捕获”)在一个命令中完成所有操作。

我知道如何在 Python 中用几行代码来做，但我真的不知道如何在 VIM 中使用 s/search_for_this/replace_that/options 来做这件事。格式。

^\s*(\w+) = 1\s*$/'\1': \1,/g

Answer 1

那应该做的工作:

%s/\v(\w+).*/'\1': \1,

我认为您的查询不起作用，因为 +符号需要斜线 \在它之前。
在我的查询中，我使用了 \v “非常神奇”的选项允许我跳过一些斜线。
