Perl::Critic(3) User Contributed Perl Documentation Perl::Critic(3)NAMEPerl::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;
DESCRIPTIONPerl::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.
Win32 and ActivePerl users can find PPM distributions of Perl::Critic
at <http://theoryx5.uwinnipeg.ca/ppms/> and Alexandr Ciornii's
downloadable executable at <http://chorny.net/perl/perlcritic.html>.
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. You can also invoke the perlcritic web-service from the
command-line by doing an HTTP-post, such as one of these:
$> POST http://perlcritic.com/perl/critic.pl < MyModule.pm
$> lwp-request -m POST http://perlcritic.com/perl/critic.pl < MyModule.pm
$> wget -q -O - --post-file=MyModule.pm http://perlcritic.com/perl/critic.pl
Please note that the perlcritic web-service is still alpha code. The
URL and interface to the service are subject to change.
Also, the Perl Development Kit (PDK 8.0) from ActiveState includes a
very slick graphical interface to Perl-Critic. For details, go to
<http://www.activestate.com/perl_dev_kit>
INTERFACE SUPPORT
This 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::Criticqw(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
maintenance Policies that affect the long-term health of the code
cosmetic Policies that only have a superficial effect
complexity Policies that specificaly 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 Altertative 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 RULESPerl::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 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, "## no critic" 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
"<jeff@imaginative-software.com>" and I'll be happy to put them into
the Perl::Critic distribution. Or if you would like to work on the
Perl::Critic project directly, check out our repository at
<http://perlcritic.tigris.org>. To subscribe to our mailing list, send
a message to mailto:dev-subscribe@perlcritic.tigris.org <mailto:dev-
subscribe@perlcritic.tigris.org>.
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
"<jeff@imaginative-software.com>".

BUGS
Scrutinizing Perl code is hard for humans, let alone machines. If you
find any bugs, particularly false-positives or false-negatives from a
Perl::Critic::Policy, please submit them to
http://rt.cpan.org/NoAuth/Bugs.html?Dist=Perl-Critic
<http://rt.cpan.org/NoAuth/Bugs.html?Dist=Perl-Critic>. Thanks.
Most policies will produce false-negatives if they cannot understand a
particular block of code.
