Hi all,

When I write gdb script, I need to set many breakpoints. such as:
b xxx_file.c:xxx_line_number

With following comamnd, I can do it more easy
-----
(defcustom what-file-line-separator ":"
  "Define the separator between file name and line number"
  :type 'string
  :group 'editing)

(defcustom what-file-line-yankp nil
  "Toggle on/off Yank to kill ring"
  :type 'boolean
  :group 'editing)

;; Maybe this variable is useless, user can copy what they want in mini-buffer                                  
(defcustom what-file-line-fullpath t
  "Toggle on/off file name fullpath"
  :type 'boolean
  :group 'editing)

(defun what-file-line ()
  "Print the current buffer's file name and line nubmer"
  (interactive)
  (let ((n (line-number-at-pos))
        (file (buffer-file-name))
        result)
    (setq result (concat file what-file-line-separator (number-to-string n)))
    (message "%s" result)
    (if what-file-line-yankp
        (kill-new result))))
-----
Q:
1. I don't know in which group the customized variables should be put?
2. The 3rd customized variable needn't, agree?
3. If this functionality is usefull, I want to implement a GUI version(as same as gdb-mouse-set-clear-breakpoint). So when user click the left margin when non-gdb-mode, user can get the filename-line pair)
 
What's your comment?
