Subject: using emacs non-interactively
Date: 17 Dec 2000 14:03:11 GMT
Can someone point me at some information on how to use
the emacs '-batch' feature?
There are examples in the texinfo docs on how to use it to
edit files, but I'd also like to get it to read stdin and
output to stdout.
And for that matter, even my attempts at using it to modify
files is running into trouble, e.g. this:
emacs some.txt -batch -f mark-whole-buffer -f fill-region -f save-buffer
Produces some strange error messages:
Mark set
Mark set
Wrong number of arguments: #[(from to &optional justify nosqueeze to-eop) >
[followed by a lot of high-byte junk].

Shouldn't that be:
emacs -batch -f [...] file.txt
?
Also, is it possible to give several '-f' arguments? You may have to
define a function and call that instead.

yes this is possible.
what i haven't figured out is how to give the command itself
arguments. I always get defeated by shell+elisp quoting if I try the
form --eval "(func arg1 arg2)".

I do something like this for popping up new windows with gnuserv.
Like:
gnudoit "(make-frame-on-display \"$DISPLAY\")"
(got that line from someone in here).
If you don't care about variable substitution, you can do:
gnudoit '(make-frame-on-display "localhost:0")'
Which is a little nicer. One of those two examples should work for
you..

Hmm...I don't have the gnuserv package. Anyone get the --eval quoting
to work with something like
emacs --eval '(message "did the command line eval thing")'
I always get "End of file during parsing"

Interesting. Running it with
emacs -q --no-site-file --eval '(message "blah blah")
works on Gnu Emacs for AIX, Linux, solaris, etc. but chokes on
NTEmacs. So it must be an NTEmacs port thing. Thanks for helping me
narrow it down. Off to NTEmacs mailing list archives, and possibly
NTEmacs bug reports....

if that is the complete command line, most likely your site init file is
fubar. try w/
emacs --batch --no-site-file --eval

Actually, I think it's a NT shell quoting rules thing. The following
line works fine from a cygwin shell:
$ gnudoit '(message "Hello from Cygwin")'
But, this fails from a standard NT command window. To get it to work
there, you need this:
C:\>gnudoit "(message \"Hello from NT\")"
