I'm having a hard time making this emacs -nw work effectively under the terminal mode (emacs -nw). Some setup information: The working server is connected via SSH, and emacs is running on the server. Usually I'm connecting using SSH and "emacs -nw" to work on my files.
The emacs config is picked up from: https://hugoheden.wordpress.com/2009/03/08/copypaste-with-emacs-in-terminal/
;; make mouse selection to be emacs region marking (require 'mouse) (xterm-mouse-mode t) (defun track-mouse (e)) (setq mouse-sel-mode t) ;; enable clipboard in emacs (setq x-select-enable-clipboard t) ;; enable copy/paste between emacs and other apps (terminal version of emacs) (unless window-system (when (getenv "DISPLAY") ;; Callback for when user cuts (defun xsel-cut-function (text &optional push) ;; Insert text to temp-buffer, and "send" content to xsel stdin (with-temp-buffer (insert text) ;; I prefer using the "clipboard" selection (the one the ;; typically is used by c-c/c-v) before the primary selection ;; (that uses mouse-select/middle-button-click) (call-process-region (point-min) (point-max) "xsel" nil 0 nil "--clipboard" "--input"))) ;; Call back for when user pastes (defun xsel-paste-function() ;; Find out what is current selection by xsel. If it is different ;; from the top of the kill-ring (car kill-ring), then return ;; it. Else, nil is returned, so whatever is in the top of the ;; kill-ring will be used. (let ((xsel-output (shell-command-to-string "xsel --clipboard --output"))) (unless (string= (car kill-ring) xsel-output) xsel-output ))) ;; Attach callbacks to hooks (setq interprogram-cut-function 'xsel-cut-function) (setq interprogram-paste-function 'xsel-paste-function) ;; Idea from ;; http://shreevatsa.wordpress.com/2006/10/22/emacs-copypaste-and-x/ ;; http://email@example.com/msg03577.html ))
The reason to have:
(require 'mouse) (xterm-mouse-mode t) (defun track-mouse (e)) (setq mouse-sel-mode t)
is to enable mouse selection over text such that the text region is highlighted just as "C-x SPC" marking the region. Then I can use "M-x w" to copy and "C-x y" to paste text within emacs and between emacs and other apps.
All look perfect except that any operations related to X are REALLY SLOW! My connection to the remote server is smooth -- the latency is usually under 100ms. But to kill one line of text using "C-x k", it takes ~5 seconds! To paste it, it takes another 5 seconds!
When copy/paste is frequent sometimes, this becomes really annoying. I think this is related to the X sever messaging, but not sure if there is good way to fix this.
Any ideas? Thanks!
