Perl::Critic::Policy::ValuesAndExpressions::ProhibitImplicitNewlines.3pm

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.
