Non-GUI Emacs with cscope

cscopeemacs

So, i'm running emacs over a crappy ssh connection and I have it set up to use cscope. I can not use X because of this…hence I'm running emacs inside putty. However, when I search for something with cscope and it opens up the other buffer, I can not
follow the links where cscope tells me which file and line number the item is on. When I go t a line number and hit enter, emacs tells me 'buffer is read-only' (it is trying to actually put in a new line instead of following the link). anyone know how I can follow those links?

I don't know about cscope for sure - but you should be able to find out the appropriate key binding by doing a "Ctrl-h m" in the buffer with all the links. This should open another buffer showing you help/key bindings on all the active modes.

E.g. if you do the same thing in a grep result buffer it indicates the key binding "C-c C-c compile-goto-error" which is used to open file at the grep line number (so it may be the same keys for cscope).

Pin Emacs buffers to windows (for cscope)

Put this in your .emacs file:

;; Toggle window dedication

(defun toggle-window-dedicated ()

"Toggle whether the current active window is dedicated or not"

(interactive)

(message 

 (if (let (window (get-buffer-window (current-buffer)))

       (set-window-dedicated-p window 

        (not (window-dedicated-p window))))

    "Window '%s' is dedicated"

    "Window '%s' is normal")

 (current-buffer)))

Then bind it to some key - I use the Pause key:

(global-set-key [pause] 'toggle-window-dedicated)

And then use it to "dedicate" the window you want locked. then cscope can only open files from its result window in some OTHER window. Works a charm. I specifically use it for exactly this purpose - keeping one source file always on screen, while using cscope in a second buffer/window, and looking at cscope results in a third.

Using Emacs to recursively find and replace in text files not already open

M-x find-name-dired: you will be prompted for a root directory and a filename pattern.
Press t to "toggle mark" for all files found.
Press Q for "Query-Replace in Files...": you will be prompted for query/substitution regexps.
Proceed as with query-replace-regexp: SPACE to replace and move to next match, n to skip a match, etc.
Press C-x s to save buffers. (You can then press y for yes, n for no, or ! for yes for all)
