redirect stdout to emacs scratch

redirect stdout to emacs scratch

[pagod]

hi everyone!

this is probably a very easy question (there has to be a way!), but i
haven't been able to find the answer, so i'm turning to this forum, hoping
someone can give me a hint!

what i want to do is very simple: i want to be able to redirect the stdout
of any program on the command line into emacs' scratch buffer -- the way it
works with less or joe or whatever. i want to do it with emacs because i'm
used to using it and i need syntax coloring, but when i try it i get the
message "standard input is not a tty". then what is it? the way i've tried
it is quite the usual way:

pagod> echo "hello, world" | emacs
emacs: standard input is not a tty

my emacs is aliased to "emacs -nw" because i'm in a terminal, so the option
is assumed by default anyway. i'm using the no-window version of emacs
because i run it from within an ssh session running zsh on a linux server,
connecting using putty from a windows workstation. emacs version is 22.2.1,
running in a SuSE 11.0.

it'd be great if someone could help me do that!

thx a lot

David

Do you really need to do it this way? You can run it quite simply
within the eshell prompt inside emacs.
M-x eshell
eshell$ echo "foo" >> #<buffer *scratch*>
eshell$ myprog >> #<buffer *scratch*>
echell$ echo "bar" >> #<buffer *scratch*>

I believe there is not any nice way to do this.

Another and perhaps more obvious solution is to run shell commands with
M-1 M-! command while in the *scratch* buffer. For example:

    M-1 M-! echo "foo"

It can actually be any prefix argument for M-!, not just number 1, but
M-1 is a good choice when ! is in the same key as 1.

I forgot to mention that you could use echo -n foo to get the output
terminated with a newline.

With eshell, commands written with elisp are used where possible, so
you may be able to do something that is not possible using external
commands alone. I use W32 and these commands work even if there are no
external executables available.

As a workaround you can also try the following:

   C-x C-f .scratch
   M-x lisp-interaction-mode
   M-x auto-revert-tail-mode

You get some sort of new scratch buffer called ".scratch". Then you can add
from the command line to this new scratch buffer with:

   echo "my text" >> .scratch

The text should appear in this new scratch buffer within seconds.

$ tty
/dev/pts/1

$ ls | tty
not a tty

You could pick up the piped input, put it somewhere and make emacs read
it after the pipe finished and input comes again from the terminal.

alias emacs-with-stdin='cat > /tmp/emacs_stdin ; emacs -nw -Q --eval "(insert-file \"/tmp/emacs_stdin\")"'

This works in bash, I don't know about zsh.
