Perl::Critic::Policy::ValuesAndExpressions::ProhibitLeadUsereContributed PerlPerl::Critic::Policy::ValuesAndExpressions::ProhibitLeadingZeros(3pm)

NAME

       Perl::Critic::Policy::ValuesAndExpressions::ProhibitLeadingZeros - Write "oct(755)" instead of "0755".

AFFILIATION

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

DESCRIPTION

       Perl interprets numbers with leading zeros as octal.  If that's what you really want, its better to use "oct" and make it obvious.

	   $var = 041;	   # not ok, actually 33
	   $var = oct(41); # ok

	   chmod 0644, $file;				   # ok by default
	   dbmopen %database, 'foo.db', 0600;		   # ok by default
	   mkdir $directory, 0755;			   # ok by default
	   sysopen $filehandle, $filename, O_RDWR, 0666;   # ok by default
	   umask 0002;					   # ok by default

CONFIGURATION

       If you want to ban all leading zeros, set "strict" to a true value in a .perlcriticrc file.

	   [ValuesAndExpressions::ProhibitLeadingZeros]
	   strict = 1

NAME

       Perl::Critic::Policy::ValuesAndExpressions::ProhibitEmptyQuotes - Write "q{}" instead of "''".

AFFILIATION

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

DESCRIPTION

       Don't use quotes for an empty string or any string that is pure whitespace.  Instead, use "q{}" to improve legibility.  Better still,
       created named values like this.	Use the "x" operator to repeat characters.

	   $message = '';      #not ok
	   $message = "";      #not ok
	   $message = "     "; #not ok

	   $message = q{};     #better
	   $message = q{     } #better

	   $EMPTY = q{};
	   $message = $EMPTY;	   #best

	   $SPACE = q{ };
	   $message = $SPACE x 5;  #best

CONFIGURATION

       This Policy is not configurable except for the standard options.
