• $. and ARGV (Score:1)

  by n1vux (1492)

  No discussion of $. would be complete without a mention of multiple commandline ARGV filenames -- $. does not reset between files, unless

  close ARGV  if eof;

  or equivalently,

  close ARGV  if eof(ARGV);

  is included in the

  while(<>)

  loop.

  eof(3) [perldoc.com]

  Otherwise excellent review!

• Minor typo in article (Score:1)

  Just spotted a minor typo in the article and I thought I'd tell you so that you might be able to update it.

  The string that separates the elements of an array when expanded in a double quoted string is stored in $". Once again, it's simple to change it to a different value.

    my @arr = (1, 2, 3);
    {
      local $" = '+';
  
      print "@arr";
    }

  This code prints 1+2+3".

  That final quotation mark shouldn't be there. :)

  Otherwise a very good article.

  All the best,

  To be honest, I missed the -l switch on command line for triggering $\ to a default newline character. Beside that, Excellent article!

    There's a good chance that my next article will be about command line switches.

  I had wanted to email you about it, but I'm pretty timid. It's a fantastic article, now if I can only remember those goodies. :) Thank you!

    There's no need to be timid. Like most writers I love getting feedback on my work. I'm glad to hear that you found it useful.
