Perl::CPerl::Critic::Policy::ValuesAndExpressions::ProhibitImplicitNewlines(3)
NAME
Perl::Critic::Policy::ValuesAndExpressions::ProhibitImplicitNewlines -
Use concatenation or HEREDOCs instead of literal line breaks in
strings.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Strings with embedded line breaks are hard to read. Use concatenation
or HEREDOCs instead.
my $foo = "Line one is quite long
Line two"; # Bad
my $foo = "Line one is quite long\nLine two"; # Better, but still hard to read
my $foo = "Line one is quite long\n"
. "Line two"; # Better still
my $foo = <<'EOF'; # Use heredoc for longer passages
Line one is quite long
Line two
Line three breaks the camel's back
EOF
CONFIGURATION
This Policy is not configurable except for the standard options.
