in reply to Perl 5.10: switch statement demo
I don't know why people want a verbatim 'switch' statement when you can use a for-statement.
I generally use a for loop in conjunction with regular expression matches, like this trivial example:
It has a lot of flexibility where you can mix and match parts and get real nice uses out of it. I've always used it fully and got very good results --without waiting for a proper switch statement.
#!/usr/bin/perl -w use strict; { for (1..40) { print; ($_ % 3 == 0) && print q! fizz!; ($_ % 5 == 0) && print q! buzz!; ($_ % 7 == 0) && print q! sausage!; print "\n"; } }
I generally use a for loop in conjunction with regular expression matches, like this trivial example:
#!/usr/bin/perl -w use strict; { my @items = qw/The three principal virtues of a programmer are Laz +iness, Impatience, and Hubris. See the Camel Book for why/; for (@items) { /^[A-Z]/ && do { print "Found a proper noun? $_\n"; next; }; /[,.]/ && do { print "This word has punctuation: $_\n"; next; }; print "This word seems uninteresting: $_\n"; } }
It has a lot of flexibility where you can mix and match parts and get real nice uses out of it. I've always used it fully and got very good results --without waiting for a proper switch statement.
"The three principal virtues of a programmer are Laziness, Impatience, and Hubris. See the Camel Book for why." -- `man perl`
