New function: what-file-line, used when writing gdb script

[richardeng]

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?
