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.
