Re: Pipe bash file contents to shell

[linuxfever]

I managed to create a part of the lisp function as follows:

(defun pipe-region-to-shell ()
(interactive)
(process-send-string "shell" (format "cd %s\n" (file-name-directory
(buffer-file-name))))
(process-send-region "shell" (region-beginning) (region-end)))

The first line makes the shell go to the directory where the bash script is,
and the second one sends the highlighted region to the shell. And all these
happen in the background as I need. The only problem is that the function
assumes that a buffer named "shell" exists.
