用cscope设置语义

标签: emacs elisp cscope emacs-semantic

我开始尝试使用emacs作为我的开发环境,我遇到了一些麻烦。我希望使用带语义的cscope来搜索我的代码库。但是,在安装cscope(使用apt-get install cscope)并将xscope.el移动到我的~/.emacs.d/后,我仍然无法使用.emacs文件调用某些设置。当我尝试调用(semanticdb-enable-cscope-databases)时,我得到一个错误,即符号的函数定义是无效的。我正在使用emacs 24.3

      ;; auto-complete.el expects ac-omni-completion-sources to be
      ;; a list of cons cells where each cell's car is a regex

现在,我真的开始写一个答案,能够随着时间的推移进行改进。这就是我到现在为止所取得的成就:

cedet有几个版本。

Emacs 24.3包含 cedet-2.0 。但是,就下面引用的集市版而言,它似乎有点过时了。 我相信在这个版本中,cscope作为semantic-symref-tool-alist中的工具之一得到支持。 信息手册中描述了变量semantic-symref-tool-alist。一个人用键击C-h i g (semantic-user) Configuring SymRef到达那里。

加载semantic-symref-tool-alist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)

我认为内置版本的cedet-2.0中的cscope支持,并且不需要额外启用cscope(?)。


官方发布来自https://sourceforge.net/projects/cedet/files/cedet/cedet-1.1.tar.gz/download cedet-1.1

在此版本中,函数semanticdb-enable-cscope-databases在文件semantic/semanticdb-cscope.el

中定义

cedet版本的cedet是 cedet-2.0 。它可以通过集市在

下获得
bzr checkout bzr://cedet.bzr.sourceforge.net/bzrroot/cedet/code/trunk cedet

在此版本中,函数semanticdb-enable-cscope-databasescedet/semantic/db-cscope.el中定义。

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cedet-2.0的集市版本。
