Non-GUI Emacs with cscope

Question

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?

Answer 1

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).

Answer 2

Changing this line in xcscope.el fixed the problem on my computer.

-(define-key cscope-list-entry-keymap [return] 'cscope-select-entry-other-window)
+(define-key cscope-list-entry-keymap (kbd "RET") 'cscope-select-entry-other-window)

Answer 3

As a workaround, I'm pressing <space> key on the cscope result line. It shows the code in the other frame, although it doesn't position the cursor there.

Answer 4

Another workaround. Just type 'o' to select what you want. It means cscope-select-entry-one-window :)

Answer 5

Could you use cscope with Tramp mode? I'm not familiar with cscope, but I've had great results using tramp mode to read/write files remotely over an SSH connection.

Answer 6

I believe GNU find version 4.2 and above supports -L to follow symbolic links. Hence,

find -L . -name *.[ch] > cscope.files
cscope -b -R -q -i cscope.files

might work well
