Perl::Critic::Policy::ValuesAndExpressions::ProhibitImplicitNewlines3pm

Use concatenation or heredocs instead of literal line breaks in strings.

Affiliation

This Policy is part of the core Perl::Critic distribution.

Overview

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
