Running Perl Scripts in Emacs (on buffer)

Running Perl Scripts in Emacs (on buffer)

[Dan Anderson]

Is it possible to execute a perl script on a buffer?  (Whether it's
through something like M-x perl-script or binding the perl script to a
lisp function).

Thanks,

-Dan

Does the buffer contain the script itself or the data you want to script
to read as standard input?  Either way, you want to use `C-x h' to mark
the whole buffer as the region, then `M-|' to pipe it to a program
(either the perl interpreter itself, or a Perl script).

No.  Without going into a shell and saving (or trying to convert my Perl
scripts into elisp) I want to just run an arbitrary perl script on a
buffer.

C-x h M-| foo.pl RET

Does this help?

How do you supply the buffer data to your perl program in this case?
What would be the arguments?

Let's say I have a file and I like to replace some words via perl
program, how I would do that?

The buffer data will be piped to the script's standard input.  M-| prompts
for a command line to execute, so you type the arguments in that prompt.

C-x h M-| scriptname oldword newword
