The following example has a statement per line.
#!/usr/bin/perl -w
use strict;
use warnings;
use Time::Format 'time_format';
printf "Hello world, today is %s\n", time_format('mm dd yyyy',time);
exit;
The following example has statements broken up into lines and is still valid:
#!/usr/bin/perl -w
use strict;
use warnings;
use Time::Format
'time_format';
printf "Hello world, today is %s\n",
time_format(
'mm dd yyyy', time
);
exit;
The following example is still valid but has unnacceptable formatting for human beings:
#!/usr/bin/perl -w
use
strict;
use
warnings;
use
Time::Format
'time_format';
printf
"Hello world, today is %s\n",
time_format(
'mm dd yyyy',
time)
;
exit
;
The following example breaks:
#!/usr/bin/perl -w
use strict;
use warnings;
use Time::Format 'time_format'
printf "Hello world, today is %s\n", time_format('mm dd yyyy',time);
exit;
Personally I use vim, set expandtab, and I break a long statement with new line and tab.
If you foresee coding perl regularly, you need a copy of
Perl Best Practices by Damian Conway.
