哪个功能模式不能与官方的CEDET 2.0一起使用

本文介绍了哪个功能模式不能与官方的CEDET 2.0一起使用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我已经在GNU Emacs 24.3上使用el-get安装了官方的CEDET 2.0，并对其进行了配置.尽管它非常适合代码跳转和完成，但不能与Emacs内置的which-function-mode一起正常使用.当主要模式是Java模式时，Emacs模式行仅显示[???]，就像没有识别到​​有效功能一样.但是，当我删除我的CEDET配置时，哪种功能模式效果很好.因此，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.

I have installed official CEDET 2.0 using el-get on GNU Emacs 24.3 and configured it. Although it works great for code jump and completion, it cannot work properly with Emacs built-in which-function-mode. When the major modes is Java mode, the Emacs mode line simply displays [???], like no valid function is recognized. But when I removed my CEDET configuration, which-function-mode works well. So I think the problem should be related to the official CEDET 2.0. I tried to manually enable which-function-mode, the problem is still persist.

我无法弄清楚我的配置出了什么问题.

I cannot figure out where it goes wrong with my configuration.

任何人都可以帮忙吗?谢谢.

Can anyone help? Thanks.

更新:如果我通过注释掉行来禁用语义(语义模式1)，那么哪个功能模式将起作用.我检查了CEDET文档，并按照我的方式启用了语义.

Update: If I disabled semantic by commenting out the line (semantic-mode 1), which-function-mode would work. I checked the CEDET documents, the semantic is enabled in the way as I did.

推荐答案

次要模式 global-semantic-idle-breadcrumbs-mode 大致类似于 which-func-mode ，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"也很相似，但是只显示了部分功能不在屏幕顶部，而不显示光标在什么地方.

The minor mode global-semantic-idle-breadcrumbs-mode is roughly similar to which-func-mode but uses the header instead of the mode line so it has more room to describe your context. There is also `global-semantic-stickyfunc-mode' which is also similar, but only shows what functions is partly off the top of the screen, not what the cursor is in.

要在不禁用语义的情况下启用原始的 which-func-mode ，您可能需要仅禁用用于集成的通知语义.将 ad-disable-advice 用于 semantic-哪可以将其关闭.CEDET的最新版本不会尝试重载which-func，因此更新到最新版本也可以.

To enable the original which-func-mode without disabling semantic, you may need to just disable the advice semantic uses for integration. Use ad-disable-advice for semantic-which to turn it off. The latest version of CEDET doesn't try to overload which-func so updating to the latest could work too.
