vim 正则表达式非贪婪匹配

问题

vim 中不能使用 .\*?。

解法

可使用 .\{-}，代替 .\*，实现非贪婪匹配。

详细说明

输入 :help non-greedy，可以看到如下帮助文档：

non-greedy If a "-" appears immediately after the "{", then a shortest match first algorithm is used (see example below). In particular, "{-}" is the same as "*" but uses the shortest match first algorithm. BUT: A match that starts earlier is preferred over a shorter match: "a{-}b" matches "aaab" in "xaaab".

    Example                 matches
    ab\{2,3}c               "abbc" or "abbbc"
    a\{5}                   "aaaaa"
    ab\{2,}c                "abbc", "abbbc", "abbbbc", etc.
    ab\{,3}c                "ac", "abc", "abbc" or "abbbc"
    a[bc]\{3}d              "abbbd", "abbcd", "acbcd", "acccd", etc.
    a\(bc\)\{1,2}d          "abcd" or "abcbcd"
    a[bc]\{-}[cd]           "abc" in "abcd"
    a[bc]\*[cd]              "abcd" in "abcd"

    The } may optionally be preceded with a backslash: \{n,m\}.

注意：实测，/\v 开头进行查找时，无法使用非贪婪模式。应该只使用 /。 参考链接： https://stackoverflow.com/questions/1305853/how-can-i-make-my-match-non-greedy-in-vim
