Perl::Critic::Policy::CodeLayout::ProhibitParensWithBuilUser(Contributed Perl DocumPerl::Critic::Policy::CodeLayout::ProhibitParensWithBuiltins(3) NAME
Perl::Critic::Policy::CodeLayout::ProhibitParensWithBuiltins - Write "open $handle, $path" instead of "open($handle, $path)". AFFILIATION
This Policy is part of the core Perl::Critic distribution. DESCRIPTION
Conway suggests that all built-in functions be called without parentheses around the argument list. This reduces visual clutter and disambiguates built-in functions from user functions. Exceptions are made for "my", "local", and "our" which require parentheses when called with multiple arguments. open($handle, '>', $filename); #not ok open $handle, '>', $filename; #ok split(/$pattern/, @list); #not ok split /$pattern/, @list; #ok CONFIGURATION
This Policy is not configurable except for the standard options. NOTES
Coding with parentheses can sometimes lead to verbose and awkward constructs, so I think the intent of Conway's guideline is to remove only the unnecessary parentheses. This policy makes exceptions for some common situations where parentheses are usually required. However, you may find other situations where the parentheses are necessary to enforce precedence, but they cause still violations. In those cases, consider using the '## no critic' comments to silence Perl::Critic. BUGS
Some builtin functions (particularly those that take a variable number of scalar arguments) should probably get parentheses. This policy should be enhanced to allow the user to specify a list of builtins that are exempt from the policy. AUTHOR

Perl::Critic::Policy::Miscellanea::ProhibitUnrestrictedNoCritic - Forbid a bare "## no critic" AFFILIATION
This Policy is part of the core Perl::Critic distribution. DESCRIPTION
A bare "## no critic" annotation will disable all the active Policies. This creates holes for other, unintended violations to appear in your code. It is better to disable only the particular Policies that you need to get around. By putting Policy names in a comma-separated list after the "## no critic" annotation, then it will only disable the named Policies. Policy names are matched as regular expressions, so you can use shortened Policy names, or patterns that match several Policies. This Policy generates a violation any time that an unrestricted "## no critic" annotation appears. ## no critic # not ok ## no critic '' # not ok ## no critic () # not ok ## no critic qw() # not ok ## no critic (Policy1, Policy2) # ok ## no critic (Policy1 Policy2) # ok (can use spaces to separate) ## no critic qw(Policy1 Policy2) # ok (the preferred style) NOTE
Unfortunately, Perl::Critic is very sloppy about parsing the Policy names that appear after a "##no critic" annotation. For example, you might be using one of these broken syntaxes... ## no critic Policy1 Policy2 ## no critic 'Policy1, Policy2' ## no critic "Policy1, Policy2" ## no critic "Policy1", "Policy2" In all of these cases, Perl::Critic will silently disable all Policies, rather than just the ones you requested. But if you use the "ProhibitUnrestrictedNoCritic" Policy, all of these will generate violations. That way, you can track them down and correct them to use the correct syntax, as shown above in the "DESCRIPTION". If you've been using the syntax that is shown throughout the Perl::Critic documentation for the last few years, then you should be fine. CONFIGURATION
