Re: Code blocks with ternary operator or trailing conditionals

Just use do blocks:

#! perl
use strict;
use warnings;

my $x = 42;

do { print "Hello "; print "world!\n"; } if 7 < $x;

43 > $x ? do { print "Yes, "; print "it is!\n";    } :
          do { print "No, ";  print "it isn't!\n"; };
[download]

Output:

12:46 >perl 865_SoPW.pl
Hello world!
Yes, it is!

12:46 >
[download]

See do.

Hope that helps,

Thanks - I am aware of 'do' -- just was hoping there was a way to 'do' it without it...	[reply]

... a way to 'do' it without it... I wouldn't say this is a better way (in fact, as kcott has pointed out below, `if { ... } else { ... }` syntax is better for what you seem to want than this or a `do` block), but it's a way: `c:\@Work\Perl\monks>perl -wMstrict -le "my $x = 42; ;; sub { print qq{Hello }; print qq{world!}; }->() if 7 < $x; ;; 43 > $x ? sub { print qq{Yes, }; print qq{it is!}; }->() : sub { print qq{No, }; print qq{it is not!}; }->() ; " Hello world! Yes, it is!` [download]	[reply] [d/l] [select]

You can factour out the `->()` part: `(43 > $x ? sub { print 'Yes, '; print 'it is!'; } : sub { print 'No, '; print 'it is not!'; } )->();` [download] لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply] [d/l] [select]

LOL - somehow I'm not sure that this will make my code read shorter and cleaner... though creative... :)	[reply]
