perlcritic
is a Perl source code analyzer. It is the executable
front-end to the Perl::Critic engine, which attempts to identify
awkward, hard to read, error-prone, or unconventional constructs in
your code. Most of the rules are based on Damian Conway's book Perl
Best Practices. However, perlcritic
is not limited to
enforcing PBP, and it will even support rules that contradict Conway.
All rules can easily be configured or disabled to your liking.
This documentation only covers how to drive this command. For all other information, including how to persistently configure this command so that you don't have to say so much on the command-line, see the documentation for Perl::Critic itself.
Before getting into all the gory details, here are some basic usage examples to help get you started.
# Report only most severe violations (severity = 5) perlcritic YourModule.pm # Same as above, but read input from STDIN perlcritic # Recursively process all Perl files beneath directory perlcritic /some/directory # Report slightly less severe violations too (severity >= 4) perlcritic -4 YourModule.pm # Same as above, but using named severity level perlcritic --stern YourModule.pm # Report all violations, regardless of severity (severity >= 1) perlcritic -1 YourModule.pm # Same as above, but using named severity level perlcritic --brutal YourModule.pm # Report only violations of things from "Perl Best Practices" perlcritic --theme pbp YourModule.pm # Report top 20 most severe violations (severity >= 1) perlcritic --top YourModule.pm # Report additional violations of Policies that match m/variables/ix perlcritic --include variables YourModule.pm # Use defaults from somewhere other than ~/.perlcriticrc perlcriticrc --profile project/specific/perlcriticrc YourModule.pm
The arguments are paths to the files you wish to analyze. You may
specify multiple files. If an argument is a directory, perlcritic
will analyze all Perl files below the directory. If no arguments
are specified, then input is read from STDIN.
Option names can be abbreviated to uniqueness and can be stated with singe or double dashes, and option values can be separated from the option name by a space or '=' (as with Getopt::Long). Option names are also case-sensitive.
--profile FILE
perlcritic
to use a profile named by FILE rather than looking
for the default .perlcriticrc file in the current directory or your
home directory. See Perl::Critic/"CONFIGURATION" for more information.
--noprofile
perlcritic
not to load any configuration file, thus reverting
to the default configuration for all Policies.
--severity N
perlcritic
to only apply Policies with a severity greater than
N
. Severity values are integers ranging from 1 (least severe) to 5 (most
severe). The default is 5. For a given --profile
, decreasing the
--severity
will usually produce more violations. You can set the default
value for this option in your .perlcriticrc file. You can also redefine
the severity
for any Policy in your .perlcriticrc file. See
"CONFIGURATION" for more information.
-5 | -4 | -3 | -2 | -1
--severity
option. For example,
"-4"
is equivalent to "--severity 4"
. If multiple shortcuts are
specified, then the most restrictive one wins. If an explicit --severity
option is also given, then all shortcut options are silently ignored. NOTE:
Be careful not to put one of the number severity shortcut options immediately
after the --top
flag or perlcritic
will interpret it as the number of
violations to report.
--severity NAME
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
--gentle | --stern | --harsh | --cruel | --brutal
--severity
option. For example,
"--cruel"
is equivalent to "--severity 2"
. If multiple shortcuts are
specified, then the most restrictive one wins. If an explicit --severity
option is also given, then all shortcut options are silently ignored.
--theme RULE
Directs perlcritic
to apply only Policies with themes that satisfy the
RULE
. Themes are arbitrary names for groups of related policies. You can
combine theme names with boolean operators to create an arbitrarily complex
RULE
. For example, the following would apply only Policies that have a
'bugs' AND 'pbp' theme:
$> perlcritic --theme='bugs && pbp' MyModule.pm
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 Perl::Critic/"POLICY THEMES"
for more information about themes.
--include PATTERN
Directs perlcritic
to apply additional Policies that match the regex
/PATTERN/imx
. Use this option to temporarily override your profile and/or
the severity settings at the command-line. For example:
perlcritic --include=layout my_file.pl
This would cause perlcritic
to apply all the CodeLayout::*
policies even
if they have a severity level that is less than the default level of 5, or
have been disabled in your .perlcriticrc file. You can specify multiple
--include
options and you can use it in conjunction with the --exclude
option. Note that --exclude
takes precedence over --include
when a Policy
matches both patterns. You can set the default value for this option in your
.perlcriticrc file.
--exclude PATTERN
Directs perlcritic
to not apply any Policy that matches the regex
/PATTERN/imx
. Use this option to temporarily override your profile and/or
the severity settings at the command-line. For example:
perlcritic --exclude=strict my_file.pl
This would cause perlcritic
to not apply the RequireUseStrict
and
ProhibitNoStrict
Policies even though they have the highest severity level.
You can specify multiple --exclude
options and you can use it in conjunction
with the --include
option. Note that --exclude
takes precedence over
--include
when a Policy matches both patterns. You can set the default
value for this option in your .perlcriticrc file.
--single-policy PATTERN
Directs perlcritic
to apply just one Policy module matching the regex
/PATTERN/imx
, and exclude all other Policies. This option has precedence
over the --severity
, --theme
, --include
, --exclude
, and --only
options. For example:
perlcritic --single-policy=nowarnings my_file.pl
This would cause perlcritic
to apply just the ProhibitNoWarnings
Policy,
regardless of the severity level setting. No other Policies would be applied.
This is equivalent to what one might intend by...
perlcritic --exclude=. --include=nowarnings my_file.pl
... but this won't work because the --exclude
option overrides the
--include
option.
The equivalent of this option can be accomplished by creating a custom profile containing only the desired policy and then running...
perlcritic --profile=customprofile --only my_file.pl
--top [ N ]
perlcritic
to report only the top N
Policy violations in each
file, ranked by their severity. If N
is not specified, it defaults to 20.
If the --severity
option (or one of the shortcuts) is not explicitly given,
the --top
option implies that the minimum severity level is "1"
(i.e. "brutal"). Users can redefine the severity for any Policy in their
.perlcriticrc file. See "CONFIGURATION" for more information. You can
set the default value for this option in your .perlcriticrc file. NOTE: Be
careful not to put one of the severity shortcut options immediately after the
--top
flag or perlcritic
will interpret it as the number of violations to
report.
--force
perlcritic
to ignore the magical "## no critic"
pseudo-pragmas
in the source code. See "BENDING THE RULES" for more information. You can
set the default value for this option in your .perlcriticrc file.
--statistics
--statistics-only
--statistics
option, but suppresses normal output and only shows
the statistics.
--verbose N | FORMAT
Sets the verbosity level or format for reporting violations. If given a
number (N
), perlcritic
reports violations using one of the predefined
formats described below. If given a string (FORMAT
), it is interpreted to
be an actual format specification. If the --verbose
option is not
specified, it defaults to either 4 or 5, depending on whether multiple files
were given as arguments to perlcritic
. You can set the default value for
this option in your .perlcriticrc file.
Verbosity Format Specification ----------- ------------------------------------------------------------- 1 "%f:%l:%c:%m\n", 2 "%f: (%l:%c) %m\n", 3 "%m at %f line %l\n", 4 "%m at line %l, column %c. %e. (Severity: %s)\n", 5 "%f: %m at line %l, column %c. %e. (Severity: %s)\n", 6 "%m at line %l, near '%r'. (Severity: %s)\n", 7 "%f: %m at line %l near '%r'. (Severity: %s)\n", 8 "[%p] %m at line %l, column %c. (Severity: %s)\n", 9 "[%p] %m at line %l, near '%r'. (Severity: %s)\n", 10 "%m at line %l, column %c.\n %p (Severity: %s)\n%d\n", 11 "%m at line %l, near '%r'.\n %p (Severity: %s)\n%d\n"
Formats are a combination of literal and escape characters similar to the way
sprintf
works. See String::Format for a full explanation of the
formatting capabilities. Valid escape characters are:
Escape Meaning ------- ---------------------------------------------------------------- %c Column number where the violation occurred %d Full diagnostic discussion of the violation %e Explanation of violation or page numbers in PBP %F Just the name of the file where the violation occurred. %f Path to the file where the violation occurred. %l Line number where the violation occurred %m Brief description of the violation %P Full name of the Policy module that created the violation %p Name of the Policy without the Perl::Critic::Policy:: prefix %r The string of source code that caused the violation %s The severity level of the violation
The purpose of these formats is to provide some compatibility with text editors that have an interface for parsing certain kinds of input. See "EDITOR INTEGRATION" for more information about that.
--list
--list-themes
--profile-proto
--only
--profile-strictness {warn|fatal|quiet}
--profile
option. Valid values
are warn
(the default), fatal
, and quiet
. For example, perlcritic
normally only warns about profiles referring to non-existent Policies, but
this option can make this situation fatal. You can set the default value for
this option in your .perlcriticrc file.
--count
-C
--Safari
--color
This option is on by default. When set, Severity 5 and 4 are colored red and yellow, respectively. Colorization only happens if STDOUT is a tty and Term::ANSIColor is installed. And it only works on non-Windows environments. Negate this switch to disable color. You can set the default value for this option in your .perlcriticrc file.
Can also be specified as --colour
.
--doc PATTERN
m/PATTERN/imx
. Since Policy modules tend to have rather long names, this
just provides a more convenient way to say something like: "perldoc
Perl::Critic::Policy::ValuesAndExpressions::RequireUpperCaseHeredocTerminator"
at the command prompt.
--quiet
--help
-?
-H
--options
--man
.
--man
perlcritic
manual and exits.
--version
-V
perlcritic
and exits.
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. perlcritic
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 on the command-line, then all Policies 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 perlcritic itself can be set before the first named block. For example, putting any or all of these at the top of your .perlcriticrc file will set the default value for the corresponding command-line 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
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 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
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.
The remaining key-value pairs are configuration parameters that will be passed into the constructor of that Policy. The constructors for most Policy modules 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 on the command line.
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 || curly'" [Modules::RequireFilenameMatchesPackage] add_themes = larry [TestingAndDebugging::RequireTestLabels] add_themes = curly moe #-------------------------------------------------------------- # I do not agree with these at all, so never load them [-NamingConventions::ProhibitMixedCaseVars] [-NamingConventions::ProhibitMixedCaseSubs] #-------------------------------------------------------------- # For all other Policies, I accept the default severity, # so no additional configuration is required for them.
Note that all policies included with the Perl::Critic distribution that have integer parameters accept underscores ("_") in their values, as with Perl numeric literals. For example,
[ValuesAndExpressions::RequireNumberSeparators] min_value = 1_000
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.
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/imx
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 Perl::Critic/"SEE ALSO" for a list of some of these distributions.
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 set of Policies when analyzing test scripts. Conversely, you may wish to enable only a specific subset of Policies when analyzing modules.
The Policies that ship with Perl::Critic are have been divided 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 scripts
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
command-line option, you can create an arbitrarily complex
rule that determines which Policies to apply. 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.
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 (or 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 pseudo-pragmas:
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"
comments direct Perl::Critic to ignore the remaining
lines of code until the end of the current block, or until a "## use
critic"
comment is found (whichever comes first). If the "## no critic"
comment 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"
comments,
use the --force
option.
A bare "## no critic"
comment 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"
pragma.
For example, this would disable the ProhibitEmptyQuotes
and
ProhibitPostfixControls
policies until the end of the block or until the
next "## use critic"
comment (whichever comes first):
## no critic (EmptyQuotes, PostfixControls); # Now exempt from ValuesAndExpressions::ProhibitEmptyQuotes $foo = ""; # Now exempt ControlStructures::ProhibitPostfixControls $barf = bar() if $foo; # Still subject 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::ProhibitMixedCaseVars my $camelHumpVar = 'foo'; # Now exempt from NamingConventions::ProhibitMixedCaseSubs sub camelHumpSub {}
The argument list must be enclosed in parentheses and must contain one or more
comma-separated barewords (i.e. don't use quotes). The "## no critic"
pragmas can be nested, and Policies named by an inner pragma will be disabled
along with those already disabled an outer pragma.
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... }
Some Policies like Documentation::RequirePodSections
apply to the entire
document, in which case violations are reported at line 1. But if the file
requires a shebang line, it is impossible to put "## no critic"
on the
first line of the file. This is a known limitation and it will be addressed
in a future release. As a workaround, you can disable the affected policies
at the command-line or in your .perlcriticrc file. But beware that this
will affect the analysis of all files.
Use this feature wisely. "## no critic"
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.
For ease-of-use, perlcritic
can be integrated with your favorite text
editor. The output-formatting capabilities of perlcritic
are specifically
intended for use with the "grep" or "compile" modes available in editors like
emacs
and vim
. In these modes, you can run an arbitrary command and the
editor will parse the output into an interactive buffer that you can click on
and jump to the relevant line of code.
The Perl::Critic team thanks everyone who has helped integrate Perl-Critic with their favorite editor. Your contributions in particular have made Perl-Critic a convenient and user-friendly tool for Perl developers of all stripes. We sincerely appreciate your hard work.
Joshua ben Jore has authored a minor-mode for emacs that allows you to run perlcritic on the current region or buffer. You can run it on demand, or configure it to run automatically when you save the buffer. The output appears in a hot-linked compiler buffer. The code and installation instructions can be found in the extras directory inside this distribution.
Scott Peshak has published perlchecker.vim, which is available at http://www.vim.org/scripts/script.php?script_id=1731.
Fritz Mehner recently added support for perlcritic
to his fantastic gVIM
plugin. In addition to providing a very Perlish IDE, Fritz's plugin enables
one-click access to perlcritic
and many other very useful utilities. And
all is seamlessly integrated into the editor. See
http://lug.fh-swf.de/vim/vim-perl/screenshots-en.html for complete details.
EPIC is an open source Perl IDE based on the Eclipse platform. Features supported are syntax highlighting, on-the-fly syntax check, content assist, perldoc support, source formatter, templating support and a Perl debugger. Go to http://e-p-i-c.sourceforge.net for more information about EPIC.
The EPIC team is currently working on integration with Perl::Critic. In the meantime, you can use the criticism pragma and EPIC will highlight violations whenever it does a syntax check on your code. I haven't tried this myself, but other folks say it works.
Josh Clark has produced an excellent Perl-Critic plugin for BBEdit. A copy is included in this distribution at extras/perl_critic_for_bbedit-1_0.zip. See http://beta.bigmedium.com/projects/bbedit-perl-critic/index.shtml for screenshots and additional installation info. Apple users rejoice!
Komodo is a proprietary IDE for Perl and several other dynamic languages. Free trial copies of Komodo can be obtained from the ActiveState website at http://www.activestate.com. For instructions on integrating perlcritic with Komodo, see extras/KomodoIntegration.pod in this distribution.
If perlcritic
has any errors itself, exits with status == 1. If there are
no errors, but perlcritic
finds Policy violations in your source code,
exits with status == 2. If there were no errors and no violations were found,
exits with status == 0.
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.
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, and half of those lines are simple use statements and simple declarations.. 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
<thaljef@cpan.org>
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
<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 <thaljef@cpan.org>
.
You are encouraged to subscribe to the mailing list; send a message to
<users-subscribe@perlcritic.tigris.org>
. See also
the archives.
You can also contact the author at <thaljef@cpan.org>
.
At least one member of the development team has started hanging around in irc://irc.perl.org/#perlcritic.
There are a number of distributions of additional Policies available. A few are listed here:
Perl::Critic::More Perl::Critic::Bangs Perl::Critic::Lax Perl::Critic::StricterSubs Perl::Critic::Swift
These distributions enable you to use Perl::Critic in your unit tests:
Test::Perl::Critic Test::Perl::Critic::Progressive
There are also a couple of distributions that will install all the Perl::Critic related modules known to the development team:
Bundle::Perl::Critic Task::Perl::Critic
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. Thanks.
Most policies will produce false-negatives if they cannot understand a particular block of code.
