NAME

       Perl::Critic - Critique Perl source code for best-practices.


SYNOPSIS

           use Perl::Critic;
           my $file = shift;
           my $critic = Perl::Critic->new();
           my @violations = $critic->critique($file);
           print @violations;


DESCRIPTION

       Perl::Critic is an extensible framework for creating and applying
       coding standards to Perl source code.  Essentially, it is a static
       source code analysis engine.  Perl::Critic is distributed with a number
       of Perl::Critic::Policy modules that attempt to enforce various coding
       guidelines.  Most Policy modules are based on Damian Conway's book Perl
       Best Practices.  However, Perl::Critic is not limited to PBP and will
       even support Policies that contradict Conway.  You can enable, disable,
       and customize those Polices through the Perl::Critic interface.  You
       can also create new Policy modules that suit your own tastes.

       For a command-line interface to Perl::Critic, see the documentation for
       perlcritic.  If you want to integrate Perl::Critic with your build
       process, Test::Perl::Critic provides an interface that is suitable for
       test programs.  Also, Test::Perl::Critic::Progressive is useful for
       gradually applying coding standards to legacy code.  For the ultimate
       convenience (at the expense of some flexibility) see the criticism
       pragma.

       If you'd like to try Perl::Critic without installing anything, there is
       a web-service available at <http://perlcritic.com>.  The web-service
       does not yet support all the configuration features that are available
       in the native Perl::Critic API, but it should give you a good idea of
       what it does.

       Also, ActivePerl includes a very slick graphical interface to Perl-
       Critic called "perlcritic-gui".  You can get a free community edition
       of ActivePerl from <http://www.activestate.com>.


PREREQUISITES

       Perl::Critic runs on Perl back to Perl 5.6.1. It relies on the PPI
       module to do the heavy work of parsing Perl.


INTERFACE SUPPORT

       The "Perl::Critic" module is considered to be a public class. Any
       changes to its interface will go through a deprecation cycle.


CONSTRUCTOR

       "new( [ -profile => $FILE, -severity => $N, -theme => $string, -include
       => \@PATTERNS, -exclude => \@PATTERNS, -top => $N, -only => $B,
       -profile-strictness => $PROFILE_STRICTNESS_{WARN|FATAL|QUIET}, -force
       => $B, -verbose => $N ], -color => $B, -pager => $string, -allow-unsafe
       => $B, -criticism-fatal => $B)"
       "new()"
           Returns a reference to a new Perl::Critic object.  Most arguments
           are just passed directly into Perl::Critic::Config, but I have
           described them here as well.  The default value for all arguments
           can be defined in your .perlcriticrc file.  See the "CONFIGURATION"
           section for more information about that.  All arguments are
           optional key-value pairs as follows:

           -profile is a path to a configuration file. If $FILE is not
           defined, Perl::Critic::Config attempts to find a .perlcriticrc
           configuration file in the current directory, and then in your home
           directory.  Alternatively, you can set the "PERLCRITIC" environment
           variable to point to a file in another location.  If a
           configuration file can't be found, or if $FILE is an empty string,
           then all Policies will be loaded with their default configuration.
           See "CONFIGURATION" for more information.

           -severity is the minimum severity level.  Only Policy modules that
           have a severity greater than $N will be applied.  Severity values
           are integers ranging from 1 (least severe violations) to 5 (most
           severe violations).  The default is 5.  For a given "-profile",
           decreasing the "-severity" will usually reveal more Policy
           violations. You can set the default value for this option in your
           .perlcriticrc file.  Users can redefine the severity level for any
           Policy in their .perlcriticrc file.  See "CONFIGURATION" for more
           information.

           If it is difficult for you to remember whether severity "5" is the
           most or least restrictive level, then you can use one of these
           named values:

               SEVERITY NAME   ...is equivalent to...   SEVERITY NUMBER
               --------------------------------------------------------
               -severity => 'gentle'                     -severity => 5
               -severity => 'stern'                      -severity => 4
               -severity => 'harsh'                      -severity => 3
               -severity => 'cruel'                      -severity => 2
               -severity => 'brutal'                     -severity => 1

           The names reflect how severely the code is criticized: a "gentle"
           criticism reports only the most severe violations, and so on down
           to a "brutal" criticism which reports even the most minor
           violations.

           -theme is special expression that determines which Policies to
           apply based on their respective themes.  For example, the following
           would load only Policies that have a 'bugs' AND 'pbp' theme:

             my $critic = Perl::Critic->new( -theme => 'bugs && pbp' );

           Unless the "-severity" option is explicitly given, setting "-theme"
           silently causes the "-severity" to be set to 1.  You can set the
           default value for this option in your .perlcriticrc file.  See the
           "POLICY THEMES" section for more information about themes.

           -include is a reference to a list of string @PATTERNS.  Policy
           modules that match at least one "m/$PATTERN/ixms" will always be
           loaded, irrespective of all other settings.  For example:

               my $critic = Perl::Critic->new(-include => ['layout'], -severity => 4);

           This would cause Perl::Critic to apply all the "CodeLayout::*"
           Policy modules even though they have a severity level that is less
           than 4. You can set the default value for this option in your
           .perlcriticrc file.  You can also use "-include" in conjunction
           with the "-exclude" option.  Note that "-exclude" takes precedence
           over "-include" when a Policy matches both patterns.

           -exclude is a reference to a list of string @PATTERNS.  Policy
           modules that match at least one "m/$PATTERN/ixms" will not be
           loaded, irrespective of all other settings.  For example:

               my $critic = Perl::Critic->new(-exclude => ['strict'], -severity => 1);

           This would cause Perl::Critic to not apply the "RequireUseStrict"
           and "ProhibitNoStrict" Policy modules even though they have a
           severity level that is greater than 1.  You can set the default
           value for this option in your .perlcriticrc file.  You can also use
           "-exclude" in conjunction with the "-include" option.  Note that
           "-exclude" takes precedence over "-include" when a Policy matches
           both patterns.

           -single-policy is a string "PATTERN".  Only one policy that matches
           "m/$PATTERN/ixms" will be used.  Policies that do not match will be
           excluded.  This option has precedence over the "-severity",
           "-theme", "-include", "-exclude", and "-only" options.  You can set
           the default value for this option in your .perlcriticrc file.

           -top is the maximum number of Violations to return when ranked by
           their severity levels.  This must be a positive integer.
           Violations are still returned in the order that they occur within
           the file. Unless the "-severity" option is explicitly given,
           setting "-top" silently causes the "-severity" to be set to 1.  You
           can set the default value for this option in your .perlcriticrc
           file.

           -only is a boolean value.  If set to a true value, Perl::Critic
           will only choose from Policies that are mentioned in the user's
           profile.  If set to a false value (which is the default), then
           Perl::Critic chooses from all the Policies that it finds at your
           site. You can set the default value for this option in your
           .perlcriticrc file.

           -profile-strictness is an enumerated value, one of
           "$PROFILE_STRICTNESS_WARN" in Perl::Critic::Utils::Constants (the
           default), "$PROFILE_STRICTNESS_FATAL" in
           Perl::Critic::Utils::Constants, and "$PROFILE_STRICTNESS_QUIET" in
           Perl::Critic::Utils::Constants.  If set to
           "$PROFILE_STRICTNESS_FATAL" in Perl::Critic::Utils::Constants,
           Perl::Critic will make certain warnings about problems found in a
           .perlcriticrc or file specified via the -profile option fatal. For
           example, Perl::Critic normally only "warn"s about profiles
           referring to non-existent Policies, but this value makes this
           situation fatal.  Correspondingly, "$PROFILE_STRICTNESS_QUIET" in
           Perl::Critic::Utils::Constants makes Perl::Critic shut up about
           these things.

           -force is a boolean value that controls whether Perl::Critic
           observes the magical "## no critic" annotations in your code. If
           set to a true value, Perl::Critic will analyze all code.  If set to
           a false value (which is the default) Perl::Critic will ignore code
           that is tagged with these annotations.  See "BENDING THE RULES" for
           more information.  You can set the default value for this option in
           your .perlcriticrc file.

           -verbose can be a positive integer (from 1 to 11), or a literal
           format specification.  See Perl::Critic::Violation for an
           explanation of format specifications.  You can set the default
           value for this option in your .perlcriticrc file.

           -unsafe directs Perl::Critic to allow the use of Policies that are
           marked as "unsafe" by the author.  Such policies may compile
           untrusted code or do other nefarious things.

           -color and -pager are not used by Perl::Critic but is provided for
           the benefit of perlcritic.

           -criticism-fatal is not used by Perl::Critic but is provided for
           the benefit of criticism.

           -color-severity-highest, -color-severity-high, -color-severity-
           medium, -color-severity-low, and -color-severity-lowest are not
           used by Perl::Critic, but are provided for the benefit of
           perlcritic.  Each is set to the Term::ANSIColor color specification
           to be used to display violations of the corresponding severity.

           -files-with-violations and -files-without-violations are not used
           by Perl::Critic, but are provided for the benefit of perlcritic, to
           cause only the relevant filenames to be displayed.


METHODS

       "critique( $source_code )"
           Runs the $source_code through the Perl::Critic engine using all the
           Policies that have been loaded into this engine.  If $source_code
           is a scalar reference, then it is treated as a string of actual
           Perl code.  If $source_code is a reference to an instance of
           PPI::Document, then that instance is used directly. Otherwise, it
           is treated as a path to a local file containing Perl code.  This
           method returns a list of Perl::Critic::Violation objects for each
           violation of the loaded Policies.  The list is sorted in the order
           that the Violations appear in the code.  If there are no
           violations, this method returns an empty list.

       "add_policy( -policy => $policy_name, -params => \%param_hash )"
           Creates a Policy object and loads it into this Critic.  If the
           object cannot be instantiated, it will throw a fatal exception.
           Otherwise, it returns a reference to this Critic.

           -policy is the name of a Perl::Critic::Policy subclass module.  The
           'Perl::Critic::Policy' portion of the name can be omitted for
           brevity.  This argument is required.

           -params is an optional reference to a hash of Policy parameters.
           The contents of this hash reference will be passed into to the
           constructor of the Policy module.  See the documentation in the
           relevant Policy module for a description of the arguments it
           supports.

       " policies() "
           Returns a list containing references to all the Policy objects that
           have been loaded into this engine.  Objects will be in the order
           that they were loaded.

       " config() "
           Returns the Perl::Critic::Config object that was created for or
           given to this Critic.

       " statistics() "
           Returns the Perl::Critic::Statistics object that was created for
           this Critic.  The Statistics object accumulates data for all files
           that are analyzed by this Critic.


FUNCTIONAL INTERFACE

       For those folks who prefer to have a functional interface, The
       "critique" method can be exported on request and called as a static
       function.  If the first argument is a hashref, its contents are used to
       construct a new Perl::Critic object internally.  The keys of that hash
       should be the same as those supported by the "Perl::Critic::new()"
       method.  Here are some examples:

           use Perl::Critic qw(critique);

           # Use default parameters...
           @violations = critique( $some_file );

           # Use custom parameters...
           @violations = critique( {-severity => 2}, $some_file );

           # As a one-liner
           %> perl -MPerl::Critic=critique -e 'print critique(shift)' some_file.pm

       None of the other object-methods are currently supported as static
       functions.  Sorry.


CONFIGURATION

       Most of the settings for Perl::Critic and each of the Policy modules
       can be controlled by a configuration file.  The default configuration
       file is called .perlcriticrc.  Perl::Critic will look for this file in
       the current directory first, and then in your home directory.
       Alternatively, you can set the "PERLCRITIC" environment variable to
       explicitly point to a different file in another location.  If none of
       these files exist, and the "-profile" option is not given to the
       constructor, then all the modules that are found in the
       Perl::Critic::Policy namespace will be loaded with their default
       configuration.

       The format of the configuration file is a series of INI-style blocks
       that contain key-value pairs separated by '='. Comments should start
       with '#' and can be placed on a separate line or after the name-value
       pairs if you desire.

       Default settings for Perl::Critic itself can be set before the first
       named block. For example, putting any or all of these at the top of
       your configuration file will set the default value for the
       corresponding constructor argument.

           severity  = 3                                     #Integer or named level
           only      = 1                                     #Zero or One
           force     = 0                                     #Zero or One
           verbose   = 4                                     #Integer or format spec
           top       = 50                                    #A positive integer
           theme     = (pbp || security) && bugs             #A theme expression
           include   = NamingConventions ClassHierarchies    #Space-delimited list
           exclude   = Variables  Modules::RequirePackage    #Space-delimited list
           criticism-fatal = 1                               #Zero or One
           color     = 1                                     #Zero or One
           allow-unsafe = 1                                  #Zero or One
           pager     = less                                  #pager to pipe output to

       The remainder of the configuration file is a series of blocks like
       this:

           [Perl::Critic::Policy::Category::PolicyName]
           severity = 1
           set_themes = foo bar
           add_themes = baz
           maximum_violations_per_document = 57
           arg1 = value1
           arg2 = value2

       "Perl::Critic::Policy::Category::PolicyName" is the full name of a
       module that implements the policy.  The Policy modules distributed with
       Perl::Critic have been grouped into categories according to the table
       of contents in Damian Conway's book Perl Best Practices. For brevity,
       you can omit the 'Perl::Critic::Policy' part of the module name.

       "severity" is the level of importance you wish to assign to the Policy.
       All Policy modules are defined with a default severity value ranging
       from 1 (least severe) to 5 (most severe).  However, you may disagree
       with the default severity and choose to give it a higher or lower
       severity, based on your own coding philosophy.  You can set the
       "severity" to an integer from 1 to 5, or use one of the equivalent
       names:

           SEVERITY NAME ...is equivalent to... SEVERITY NUMBER
           ----------------------------------------------------
           gentle                                             5
           stern                                              4
           harsh                                              3
           cruel                                              2
           brutal                                             1

       The names reflect how severely the code is criticized: a "gentle"
       criticism reports only the most severe violations, and so on down to a
       "brutal" criticism which reports even the most minor violations.

       "set_themes" sets the theme for the Policy and overrides its default
       theme.  The argument is a string of one or more whitespace-delimited
       alphanumeric words.  Themes are case-insensitive.  See "POLICY THEMES"
       for more information.

       "add_themes" appends to the default themes for this Policy.  The
       argument is a string of one or more whitespace-delimited words. Themes
       are case- insensitive.  See "POLICY THEMES" for more information.

       "maximum_violations_per_document" limits the number of Violations the
       Policy will return for a given document.  Some Policies have a default
       limit; see the documentation for the individual Policies to see whether
       there is one.  To force a Policy to not have a limit, specify
       "no_limit" or the empty string for the value of this parameter.

       The remaining key-value pairs are configuration parameters that will be
       passed into the constructor for that Policy.  The constructors for most
       Policy objects do not support arguments, and those that do should have
       reasonable defaults.  See the documentation on the appropriate Policy
       module for more details.

       Instead of redefining the severity for a given Policy, you can
       completely disable a Policy by prepending a '-' to the name of the
       module in your configuration file.  In this manner, the Policy will
       never be loaded, regardless of the "-severity" given to the
       Perl::Critic constructor.

       A simple configuration might look like this:

           #--------------------------------------------------------------
           # I think these are really important, so always load them

           [TestingAndDebugging::RequireUseStrict]
           severity = 5

           [TestingAndDebugging::RequireUseWarnings]
           severity = 5

           #--------------------------------------------------------------
           # I think these are less important, so only load when asked

           [Variables::ProhibitPackageVars]
           severity = 2

           [ControlStructures::ProhibitPostfixControls]
           allow = if unless  # My custom configuration
           severity = cruel   # Same as "severity = 2"

           #--------------------------------------------------------------
           # Give these policies a custom theme.  I can activate just
           # these policies by saying `perlcritic -theme larry`

           [Modules::RequireFilenameMatchesPackage]
           add_themes = larry

           [TestingAndDebugging::RequireTestLables]
           add_themes = larry curly moe

           #--------------------------------------------------------------
           # I do not agree with these at all, so never load them

           [-NamingConventions::Capitalization]
           [-ValuesAndExpressions::ProhibitMagicNumbers]

           #--------------------------------------------------------------
           # For all other Policies, I accept the default severity,
           # so no additional configuration is required for them.

       For additional configuration examples, see the perlcriticrc file that
       is included in this examples directory of this distribution.

       Damian Conway's own Perl::Critic configuration is also included in this
       distribution as examples/perlcriticrc-conway.


THE POLICIES

       A large number of Policy modules are distributed with Perl::Critic.
       They are described briefly in the companion document
       Perl::Critic::PolicySummary and in more detail in the individual
       modules themselves.  Say "perlcritic -doc PATTERN" to see the perldoc
       for all Policy modules that match the regex "m/PATTERN/ixms"

       There are a number of distributions of additional policies on CPAN. If
       Perl::Critic doesn't contain a policy that you want, some one may have
       already written it.  See the "SEE ALSO" section below for a list of
       some of these distributions.


POLICY THEMES

       Each Policy is defined with one or more "themes".  Themes can be used
       to create arbitrary groups of Policies.  They are intended to provide
       an alternative mechanism for selecting your preferred set of Policies.
       For example, you may wish disable a certain subset of Policies when
       analyzing test programs.  Conversely, you may wish to enable only a
       specific subset of Policies when analyzing modules.

       The Policies that ship with Perl::Critic have been broken into the
       following themes.  This is just our attempt to provide some basic
       logical groupings.  You are free to invent new themes that suit your
       needs.

           THEME             DESCRIPTION
           --------------------------------------------------------------------------
           core              All policies that ship with Perl::Critic
           pbp               Policies that come directly from "Perl Best Practices"
           bugs              Policies that that prevent or reveal bugs
           certrec           Policies that CERT recommends
           certrule          Policies that CERT considers rules
           maintenance       Policies that affect the long-term health of the code
           cosmetic          Policies that only have a superficial effect
           complexity        Policies that specifically relate to code complexity
           security          Policies that relate to security issues
           tests             Policies that are specific to test programs

       Any Policy may fit into multiple themes.  Say "perlcritic -list" to get
       a listing of all available Policies and the themes that are associated
       with each one.  You can also change the theme for any Policy in your
       .perlcriticrc file.  See the "CONFIGURATION" section for more
       information about that.

       Using the "-theme" option, you can create an arbitrarily complex rule
       that determines which Policies will be loaded.  Precedence is the same
       as regular Perl code, and you can use parentheses to enforce precedence
       as well.  Supported operators are:

           Operator    Alternative    Example
           -----------------------------------------------------------------
           &&          and            'pbp && core'
           ||          or             'pbp || (bugs && security)'
           !           not            'pbp && ! (portability || complexity)'

       Theme names are case-insensitive.  If the "-theme" is set to an empty
       string, then it evaluates as true all Policies.


BENDING THE RULES

       Perl::Critic takes a hard-line approach to your code: either you comply
       or you don't.  In the real world, it is not always practical (nor even
       possible) to fully comply with coding standards.  In such cases, it is
       wise to show that you are knowingly violating the standards and that
       you have a Damn Good Reason (DGR) for doing so.

       To help with those situations, you can direct Perl::Critic to ignore
       certain lines or blocks of code by using annotations:

           require 'LegacyLibaray1.pl';  ## no critic
           require 'LegacyLibrary2.pl';  ## no critic

           for my $element (@list) {

               ## no critic

               $foo = "";               #Violates 'ProhibitEmptyQuotes'
               $barf = bar() if $foo;   #Violates 'ProhibitPostfixControls'
               #Some more evil code...

               ## use critic

               #Some good code...
               do_something($_);
           }

       The "## no critic" annotations direct Perl::Critic to ignore the
       remaining lines of code until a "## use critic" annotation is found. If
       the "## no critic" annotation is on the same line as a code statement,
       then only that line of code is overlooked.  To direct perlcritic to
       ignore the "## no critic" annotations, use the "--force" option.

       A bare "## no critic" annotation disables all the active Policies.  If
       you wish to disable only specific Policies, add a list of Policy names
       as arguments, just as you would for the "no strict" or "no warnings"
       pragmas.  For example, this would disable the "ProhibitEmptyQuotes" and
       "ProhibitPostfixControls" policies until the end of the block or until
       the next "## use critic" annotation (whichever comes first):

           ## no critic (EmptyQuotes, PostfixControls)

           # Now exempt from ValuesAndExpressions::ProhibitEmptyQuotes
           $foo = "";

           # Now exempt ControlStructures::ProhibitPostfixControls
           $barf = bar() if $foo;

           # Still subjected to ValuesAndExpression::RequireNumberSeparators
           $long_int = 10000000000;

       Since the Policy names are matched against the "## no critic" arguments
       as regular expressions, you can abbreviate the Policy names or disable
       an entire family of Policies in one shot like this:

           ## no critic (NamingConventions)

           # Now exempt from NamingConventions::Capitalization
           my $camelHumpVar = 'foo';

           # Now exempt from NamingConventions::Capitalization
           sub camelHumpSub {}

       The argument list must be enclosed in parentheses or brackets and must
       contain one or more comma-separated barewords (e.g. don't use quotes).
       The "## no critic" annotations can be nested, and Policies named by an
       inner annotation will be disabled along with those already disabled an
       outer annotation.

       Some Policies like "Subroutines::ProhibitExcessComplexity" apply to an
       entire block of code.  In those cases, the "## no critic" annotation
       must appear on the line where the violation is reported.  For example:

           sub complicated_function {  ## no critic (ProhibitExcessComplexity)
               # Your code here...
           }

       Policies such as "Documentation::RequirePodSections" apply to the
       entire document, in which case violations are reported at line 1.

       Use this feature wisely.  "## no critic" annotations should be used in
       the smallest possible scope, or only on individual lines of code. And
       you should always be as specific as possible about which Policies you
       want to disable (i.e. never use a bare "## no critic").  If
       Perl::Critic complains about your code, try and find a compliant
       solution before resorting to this feature.


THE Perl::Critic PHILOSOPHY

       Coding standards are deeply personal and highly subjective.  The goal
       of Perl::Critic is to help you write code that conforms with a set of
       best practices.  Our primary goal is not to dictate what those
       practices are, but rather, to implement the practices discovered by
       others.  Ultimately, you make the rules -- Perl::Critic is merely a
       tool for encouraging consistency.  If there is a policy that you think
       is important or that we have overlooked, we would be very grateful for
       contributions, or you can simply load your own private set of policies
       into Perl::Critic.


EXTENDING THE CRITIC

       The modular design of Perl::Critic is intended to facilitate the
       addition of new Policies.  You'll need to have some understanding of
       PPI, but most Policy modules are pretty straightforward and only
       require about 20 lines of code.  Please see the Perl::Critic::DEVELOPER
       file included in this distribution for a step-by-step demonstration of
       how to create new Policy modules.

       If you develop any new Policy modules, feel free to send them to
       "<team@perlcritic.com>" and I'll be happy to consider putting them into
       the Perl::Critic distribution.  Or if you would like to work on the
       Perl::Critic project directly, you can fork our repository at
       <https://github.com/Perl-Critic/Perl-Critic.git>.

       The Perl::Critic team is also available for hire.  If your organization
       has its own coding standards, we can create custom Policies to enforce
       your local guidelines.  Or if your code base is prone to a particular
       defect pattern, we can design Policies that will help you catch those
       costly defects before they go into production. To discuss your needs
       with the Perl::Critic team, just contact "<team@perlcritic.com>".
