Perl and Emacs

loosid has asked for the wisdom of the Perl Monks concerning the following question:


I am trying to configure E-Macs to use Perl but for some
reason it won't read in user input. For example, the code: 

print "what's your name?   ";
$name = <stdin>;
chomp $name; 
print "hello, $name!\n";


has the following output in emacs:
what's your name? hello, !

This script works on a command prompt, but not in emacs. Any 
help would be much appreciated.

Thanks, 

Matt

In most .emacs setups, M-! (ie executing a shell command) invokes a non-interactive shell. usually this is because you use this to run non-interactive tasks, ie no stdin , just a command (like make). What you want to do is open a shell in a new frame, not run a shell command. I'm not if there's a default key binding for this, but since i use xemacs i can just click on the "Tools" menu. Although i find a real shell to be much nicer than an emacs one :-) BlueLines	[reply]

I'm not an emacs expert but the shells inside emacs seem to "steal" the new lines, so the redirection that you hope for (keyboard ---> program's STDIN) doesn't work. This one works for me though: `echo "MYNAME" \| perl -e ' ...your program here...'` [download] HTH	[reply] [d/l]

Also, here's what the shell entry looks like in my .emacs file: `;;; ;;; Shell-mode ;;; ---------- (setf sh-shell-file "/bin/sh")` [download] BlueLines	[reply] [d/l]
