Vim映射不起作用？

Question

我最近刚刚开始使用 vim，并且在添加有用的插件时感到非常有趣。问题是，在设置所有插件期间的某个时刻，我没有注意到回车键的映射停止正常工作。在插入模式下，当我按 Enter 时，如果当前没有自动完成菜单，则不会创建换行符，而是打印以下内容：

pumvisible() ? "\" : "\"

这是我的 vimrc：

我是 vim 新手，所以如果有任何内容其他需要的请告诉我。

Answer 1

Supertab 包括到的映射。与“inoremap...”映射冲突。具体来说，如果超级选项卡在另一个选项卡之后加载，则会破坏它。如果 inoremap 映射是在 supertab 加载之后出现的，那么它就可以工作。

您可以通过将 inoremap 映射放入 .vim/after/plugin/mappings.vim 或类似文件中，在 supertab 之后进行映射。

Answer 2

您可以尝试发出命令 :map，该命令将列出回车符的当前映射。如果这没有帮助，也许你可以尝试在所有已加载的插件文件中使用 grep 来查找与 map 和/或 pumvisible 匹配的字符串。

Answer 3

这个映射应该做什么？

inoremap <expr> <cr> pumvisible() ? "\<c-y>" : "\<c-g>u\<cr>"

看来这就是你的问题了。不知道如何修复它，但我很确定如果您将其取出并重新启动，您的返回键将再次起作用。我不明白，因为 return 接受我开箱即用的选定完成。
