vimscript buffer to get output of perl script

Question

I'm trying to edit the copy-paste buffer:

I have the following command:

nmap gfb :let .shellescape(getreg('0'))=1<br>

that should have put the number 1 into the buffer, which is not happening.

how do i put the output of a perl script into a vimscript buffer?

Answer 1

To get the output of an external command into a vim buffer you use system:

:let @0 = system("/bin/ls")
:echo @0

I'm not sure how this relates to Perl exactly. You might want to edit your question to clarify.
