vim 支持 cscope：
root@lab:/home/mirror0/chrome# vim --version | grep cscope
+cryptv +cscope +cursorshape +dialog_con_gui +diff +digraphs +dnd -ebcdic
其实没有安装cscope命令：
root@lab:/home/mirror0/chrome# which cscope
那么，为什么 vim 支持 cscope 而没有安装 cscope？
【问题讨论】：
-
支持 cscope 意味着：vim 知道如何与 cscope 交互。
vim can, but not have to. -
@kev 你知道vim如何与cscope交互吗？
-
在 vim 中输入
:help if_cscop.txt。 -
@hugemeow 只有当您已经打开帮助时，前者才会导致相同的帮助页面。如果你没有，有
:h cscope。不能说是@kev，但:h cscope在:h if_cscop.txt标签下面的五行，这就是为什么你可能想要引用它的原因。还有help.txt文件搜索/\ccscope会找到行|if_cscop.txt| using Cscope with Vim。 -
@hugemeow
help.txt在您不带任何参数地执行:h时打开。模式中的\c用于不区分大小写的搜索，但如果您有set incsearch，则在键入/cs时会出现所需的结果（假设您打算使用/cscope搜索cscope）。
