Inside a here doc, how can I force an expression to be evaluated
such as localtime:
print <<"END";
`localtime time`
Foo
Bar
END
I know I can simply create the var before,
my $var = localtime time;
But just curious how to evaluate expressions inside this...
You can use the trick mentioned in 'perldoc -q string' "How do I expand
function calls in a string?", referencing, then dereferencing an array, but
it is ugly:
print <<"END";
@{ [`localtime time`] }
Foo
Bar
END
localtime is a Perl function, not an external command, so:
print <<END;
@{[ localtime time ]}
Foo
Bar
END
