Pipe bash file contents to shell

Pipe bash file contents to shell

[linuxfever]

Hello all,

I was wondering whether there is a way to pass contents of a bash script
file into a shell buffer in Emacs (23.2). For example, if my bash file
contains a single line "ls -al", I would like to highlight that line, and by
pressing a keybind, have the command executed and its output shown in the
shell buffer.

Is it at all possible? Thanks for any suggestions!

eh, correcting my previous messages.
"shell-command-on-region" is here not the right starting point.

So let me consider your question again:

you have a bash-script. To which directory would `ls -al' point?
How it's written?

Basically it's possible.
However, maybe to get the results you want, Emacs provides better ways, 
for example via dired.

So, the idea is that my script will contain lines of this form:

./c_code args

where c_code is a C program in the same directory where my bash file is.
Therefore, the idea is the following:

1) Highlight line
2) open shell (if one does not exist already) and cd to the directory where
the bash file is
3) send the line to the shell

Ideally, all this would be happening in the background; something similar to
what ESS does for the R language.

Thanks for your help!

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.

You want get-buffer-create I think

get-buffer-create is a built-in function in `C source code'.

(get-buffer-create BUFFER-OR-NAME)

Return the buffer specified by BUFFER-OR-NAME, creating a new one if needed.
If BUFFER-OR-NAME is a string and a live buffer with that name exists,
return that buffer.  If no such buffer exists, create a new buffer with
that name and return it.  If BUFFER-OR-NAME starts with a space, the new
buffer does not keep undo information.

If BUFFER-OR-NAME is a buffer instead of a string, return it as given,
even if it is dead.  The return value is never nil.

There is eev mode http://www.emacswiki.org/emacs/EevMode which seems
to have similar described functionality.  But Ive not quite it to
work :-)
