While reading 'mastering perl', I run into @- and @+ for the first time. Trying to understand what's going on, I ran the code from the book, but
$-[1] and $+[1] shoudln't match only the first match? (in this case, shoudln't it be, 7 to 8 ?, instead of 7 to 9 ?) --code-- #!/usr/bin/perl $alphabet = "abcdefghijklmnopqrstuvwxyz"; $alphabet =~ /(hi).*(stu)/; print "\$alphabet is $alphabet\n"; print "We are looking from h to u\n"; print "match is \$& , which is $&\n"; print "\$` is $`\n"; print "\$' is $'\n"; print "\$1 is $1\n"; print "\$2 is $2\n"; print "The entire match began at $-[0] and ended at $+[0]\n"; print "The first match began at $-[1] and ended at $+[1]\n"; print "The second match began at $-[2] and ended at $+[2]\n"; --running them-- ./regex-3.pl $alphabet is abcdefghijklmnopqrstuvwxyz We are looking from h to u match is $& , which is hijklmnopqrstu $` is abcdefg $' is vwxyz $1 is hi $2 is stu The entire match began at 7 and ended at 21 The first match began at 7 and ended at 9 The second match began at 18 and ended at 21 -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
