我开始尝试使用emacs作为我的开发环境,我遇到了一些麻烦。我希望使用具有语义的cscope,以便在我的代码库中进行相当健壮的搜索。但是,在安装了cscope (使用apt-get install cscope)并将xscope.el迁移到我的~/.emacs.d/之后,我仍然很难用xscope.el文件调用一些设置。当我试图调用(semanticdb-enable-cscope-databases)时,会发现一个错误,即符号的函数定义无效。我使用的是emacs 24.3

现在,我真的开始写一个答案,以便能够随着时间的推移来完善它。这就是我到现在为止的成就:
有几个版本的cedet。
Emacs24.3包括cedet-2.0。但是,关于下面引用的集市版本,它似乎有点过时了。我相信在这个版本中,cscope是semantic-symref-tool-alist中支持的工具之一。变量semantic-symref-tool-alist在信息手册中进行了描述。其中一个是用键笔画C-h i g (semantic-user) Configuring SymRef到达的。
在加载semantic-symref-tool-alist之后,可以看到semantic/symref的默认值。其成员之一是:
((lambda
(rootdir)
(file-exists-p
(expand-file-name "cscope.out" rootdir)))
. cscope)我认为这个是,是cscope内置版本的cscope支持,不需要额外的启用(?)
官方发布的是cedet-1.1,来自https://sourceforge.net/projects/cedet/files/cedet/cedet-1.1.tar.gz/download。
在这个版本中,函数semanticdb-enable-cscope-databases定义在文件semantic/semanticdb-cscope.el中。
市场版的cedet是cedet-2.0。它可通过集市获得,网址如下:
bzr checkout bzr://cedet.bzr.sourceforge.net/bzrroot/cedet/code/trunk cedet在这个版本中,函数semanticdb-enable-cscope-databases是在cedet/semantic/db-cscope.el中定义的。
在emacs 24.3附带的cedet版本中缺少此文件。
Σ:这让我相信,如果你想使用你的设置,你应该使用市场版的cedet-2.0。
