ターミナル上で動いているEmacsで、選択範囲をXのクリップボードにコピーする

Posted at 2016-10-02

ELispをほとんど書いていないので、正しいやり方なのか全然わからないが、とりあえずできた。
ただxselの動作があまり安定しない。短いテキストなら問題ないが・・・

;; Region to X clipboard
(defun paste-to-tmp-file(data)
  (with-temp-buffer
    (insert data)
    (write-file "/tmp/clipboard")))
  
(defun xclip-add-region()
  (interactive)
  (if (region-active-p)
      (progn
        (paste-to-tmp-file (buffer-substring-no-properties (region-beginning) (region-end)))
        (shell-command "xsel -ib < /tmp/clipboard")
        (message "%s" (shell-command-to-string "cat /tmp/clipboard")))
    (progn
      (message "no region"))))

(bind-key "C-c C-c" 'xclip-add-region)
