Perl::Critic::Policy::ValuesAndExpressions::ProhibitCommUseraContriPerl::Critic::Policy::ValuesAndExpressions::ProhibitCommaSeparatedStatements(3)NAME
Perl::Critic::Policy::ValuesAndExpressions::ProhibitCommaSeparatedStatements - Don't use the comma operator as a statement separator.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Perl's comma statement separator has really low precedence, which leads to code that looks like it's using the comma list element separator
not actually doing so. Conway suggests that the statement separator not be used in order to prevent this situation.
The confusion that the statement separator causes is primarily due to the assignment operators having higher precedence.
For example, trying to combine two arrays into another like this won't work:
@x = @y, @z;
because it is equivalent to
@x = @y;
@z;
Conversely, there are the built-in functions, like "print", that normally force the rest of the statement into list context, but don't when
called like a subroutine.
This is not likely to produce what is intended:
print join q{, }, 2, 3, 5, 7, ": the single-digit primes.
";
The obvious fix is to add parentheses. Placing them like
print join( q{, }, 2, 3, 5, 7 ), ": the single-digit primes.
";
will work, but
print ( join q{, }, 2, 3, 5, 7 ), ": the single-digit primes.
";
will not, because it is equivalent to
print( join q{, }, 2, 3, 5, 7 );
": the single-digit primes.
";
CONFIGURATION
This policy can be configured to allow the last statement in a "map" or "grep" block to be comma separated. This is done via the
"allow_last_statement_to_be_comma_separated_in_map_and_grep" option like so:
[ValuesAndExpressions::ProhibitCommaSeparatedStatements]
allow_last_statement_to_be_comma_separated_in_map_and_grep = 1
With this option off (the default), the following code violates this policy.
%hash = map {$_, 1} @list;
With this option on, this statement is allowed. Even if this option is off, using a fat comma "=>" works, but that forces stringification
on the first value, which may not be what you want.
BUGS
Needs to check for "scalar( something, something )".
