是什么导致 Vim 中的替换每行只匹配一个元素？

我已经对我的自己做了很多改变.vimrc最近，我在某个地方引入了一个不受欢迎的功能。当执行搜索标记每行出现多次的替换命令时，只有第一个标记会发生更改（尽管其余标记会因替换而突出显示）。我在这里看到了一些关于如何根据具体情况启用此行为的帖子，但我还没有看到有关什么会导致此行为成为默认行为或如何禁用它的信息。如果有人有任何想法，他们将不胜感激。

最后，我禁用了所有插件，但问题并没有解决。我删除了我的.vimrc并且问题已解决（因此这不是我无法控制的全局设置）。我禁用了我的几个单独的设置.vimrc，但我似乎无法消除这个问题。最终，我厌倦了打地鼠游戏，决定转向社区。有任何想法吗？

编辑：举个例子，

我使用命令:%s/foo/foobar/g

文本foo bar foo被转换为foobar bar foo

编辑：由 pb2q 解决。set gdefault反转的行为/g.

替代命令接受开关g，对于全局，这会导致对该行的所有匹配项进行替换：

:s/regex/replacement/g

The default是只替换第一次出现的匹配项，但有一个设置可以将默认值切换为global: gdefault. So set gdefault如果您希望将此作为默认行为，请在您的 vimrc 中添加。首先在当前的 vim 会话中尝试一下:set gdefault.

请注意，当您设置gdefault，这不仅使得g默认行为，但它改变了g标志以便使用/g替换结束时将导致替换仅进行一次。

See: :help gdefault.
