SPUG: SPUG Project Ideas

[B.Ingerson at epixtech.com]

Andy,

I actually played with this concept a while ago. I found that the best way
to do it is to open a pipe to the shell and pass the one-liner in verbatim.
(perl -le 'print "That";') Actually, not quite verbatim. You tack on the
extra args to '1_r' as extra args to the one-liner. This works great on
Unix. Haven't tried it on Win32.

Wrapping in a system() call is bad because perl might interpolate syntax
meant for the shell.

I like both ideas.  One thought about the one-liner, though, is that many
one-liners actually include the Perl command, with -e, so they can include
other flags (such as -n, -l, etc.).  Do you have an idea how this could be
accommodated?  One solution might be to wrap it in a system() call.  But I
don't know how portable that would be.  Or, since they'd all be one-liners,
maybe assume they all have the form of "perl -e".
