在emacs中重建cscope

Question

我在emacs中内置了cscope。

当我使用emacs修改代码的时候。代码更改导致cscope不能按照我希望的方式运行。例如：如果我想跳转到函数定义，这是由于代码更改。cscope并没有把我带到函数的定义上，相反，它把我带到了另一行。

请告知是否有一种方法可以在不关闭emacs窗口的情况下重建cscope。

Answer 1

您将需要https://github.com/dkogan/xcscope.el和配置：

(defun my-c-mode-common-hook ()
 (require 'xcscope)
    (cscope-setup)
    (setq cscope-initial-directory "path to the cscope directory"))
  (add-hook 'c-mode-common-hook 'my-c-mode-common-hook)

然后

C-c s L (or M-x cscope-create-list-of-files-to-index)
C-c s I (or M-x cscope-index-files) => build or rebuild

希望这对你有所帮助

我使用以下函数来构建/重建cscope数据库：

    (require 'xcscope)
    (cscope-setup)
    (setq cscope-option-use-inverted-index t)
    (defadvice cscope-bury-buffer (after cscope-bury-buffer activate)
      "Kill the *cscope* window after hitting q or Q instead of leaving it open."
      (delete-window))
    (defun cscope-create-database (top-directory)
      "Create cscope* files in one step containing, do this before using cscope:
    1. C-c s L
    2. C-c s I
    3. C-c s a
    "
      (interactive "DCreate cscope* database files in directory: ")
      (progn
            (cscope-create-list-of-files-to-index top-directory)
            (cscope-index-files top-directory)
            (setq cscope-initial-directory top-directory)
            (sit-for 2)
            (delete-windows-on "*cscope-indexing-buffer*")
            (kill-buffer "*cscope-indexing-buffer*")
            ))
    (bind-keys*
    ("C-c s r" . cscope-create-database))
