Perl::Critic::Policy::Miscellanea::RequireRcsKeywords(3)

NAME
Perl::Critic::Policy::Miscellanea::RequireRcsKeywords - Put source-control keywords in every file.

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

DESCRIPTION
Every code file, no matter how small, should be kept in a source-control repository. Adding the magical RCS keywords to your file helps the reader know where the file comes from, in case he or she needs to modify it. This Policy scans your file for comments that look like this:

    # $Revision: 2721 $
    # $Source: /myproject/lib/foo.pm $

A common practice is to use the "Revision" keyword to automatically define the $VERSION variable like this:

    our ($VERSION) = '$Revision: 2721 $' =~ m{ \$Revision: \s+ (\S+) }x;

CONFIGURATION
By default, this policy only requires the "Revision", "Source", and "Date" keywords. To specify alternate keywords, specify a value for "keywords" of a whitespace delimited series of keywords (without the dollar-signs). This would look something like the following in a .perlcriticrc file:

    [Miscellanea::RequireRcsKeywords]
    keywords = Revision Source Date Author Id

See the documentation on RCS for a list of supported keywords. Many source control systems are descended from RCS, so the keywords supported by CVS and Subversion are probably the same.
