What is the value of $ testModule = ~ s @ / @ :: @ig; in Perl?
I am new to Perl and I am reading some perl codes, I find one line below, I couldn't figure out if anyone can tell what does
s@/@::@ig
I know I'm =~
trying to match some regex. normally I would see code like s/<regular express>//gi
, so I confused the following code a bit. can anyone help with the development?
$testModule =~ s@/@::@ig;

You can use many different characters as regex delimiters.
This one is used @
instead /
, so it can be used /
as data inside a regex without leaving it.
This is equivalent to:
$testModule =~ s/\//::/ig;
See the quote and quote operators in the Perl documentation for details .
