Question

我在GNU Emacs 24.3上使用el-get安装了官方CEDET 2.0并对其进行了配置。尽管它对于代码跳转和完成非常有用，但它无法与Emacs内置的功能模式一起正常工作。当主要模式是Java模式时，Emacs模式行只显示[???]，就像没有识别有效功能一样。但是当我删除了我的CEDET配置时，哪个功能模式运行良好。所以我认为问题应该与官方的CEDET 2.0有关。我试图手动启用哪个功能模式，问题仍然存在。

我无法弄清楚我的配置出了什么问题。

有人可以帮忙吗？感谢。

更新如果我通过注释掉行（语义模式1）来禁用语义，那么函数模式将起作用。我检查了CEDET文档，语义是按照我的方式启用的。

次要模式global-semantic-idle-breadcrumbs-mode与which-func-mode大致相似，但使用标题而不是模式行，因此它有更多空间来描述您的上下文。还有“global-semantic-stickyfunc-mode”也类似，但只显示哪些功能部分偏离屏幕顶部，而不是光标所在。

要启用原始which-func-mode而不禁用语义，您可能需要禁用语义用于集成的建议。使用ad-disable-advice semantic-which将其关闭。最新版本的CEDET不会尝试重载哪个函数，因此更新到最新版本也可以正常工作。
