;;; screensend.el
;;; -------------
;;;
;;; Simple Emacs script to allow you to send selected blocks of text to a
;;; running screen or tmux session. This is useful for sending text to interactive
;;; programs like clojure, psql, etc. in cases where the built-in term-mode is
;;; too slow.
;;;
;;; # Usage:
;;;
;;; ; for screen
;;; (require 'screensend)
;;; (global-set-key [f4] 'screen-select)
;;; (global-set-key [f5] 'screen-send)
;;;
;;; ; for tmux
;;; (require 'screensend)
;;; (global-set-key [f4] 'tmux-select)
;;; (global-set-key [f5] 'tmux-send)
;;;
;;; Start a screen session:
;;;
;;; screen -S mysession
;;;
;;; Or if you're using tmux:
;;;
;;; tmux new-session -s mysession
;;;
;;; Now press F4 and select "mysession"
;;;
;;; Now either select some text or place the cursor in between a text paragraph
;;; and hit F5.
;;;
;;; The selected text is transmitted to the screen session.
;;; Code:
(require 'dash)
