The (.*?) pattern will match an empty string.
Thus $0 gets the dollar sign, $1 is "", and "$" ~ "" (i.e., "$") gets replaced
by "" ~ "USD" (i.e., "USD").
So the net result is to replace the single dollar sign by "USD", resulting in
"USD1.23".
You might want to remove the ? modifier from .*?
Hi All,
What am I doing wrong here?
$ p6 'my $x="\$1.23"; $x~~s/("\$") (.*?)/$1USD/; say $x;'
USD1.23
I am expecting to see `1.23USD`
Many thanks,
-T
