NAME

Perl::Critic::Policy::logicLAB::RequireVersionFormat - assert version number formats

AFFILIATION

This policy is part of Perl::Critic::logicLAB distribution.

VERSION

This documentation describes version 0.05

DESCRIPTION

This policy asserts that a specified version number conforms to a specified format.

The default format is the defacto format used on CPAN. X.X and X.X_X where X is an arbitrary integer, in the code this is expressed using the following regular expression:

\A\d+\.\d+(_\d+)?\z

The following example lines would adhere to this format:

  • 0.01, a regular release

  • 0.01_1, a developer release

Scope, quoting and representation does not matter. If the version specification is lazy please see "EXCEPTIONS".

The following example lines would not adhere to this format and would result in a violation.

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

  • $VERSION = '0.0.1';

  • $MyPackage::VERSION = 1.0.61;

  • use version; our $VERSION = qv(1.0.611);

  • $VERSION = "0.01a";

In addition to the above examples, there are variations in quoting etc. all would cause a violation.

EXCEPTIONS

In addition there are some special cases, were we simply ignore the version, since we cannot assert it in a reasonable manner.

  • our $VERSION = $Other::VERSION;

    We hope that $Other::VERSION conforms where defined, so we ignore for now.

CONFIGURATION AND ENVIRONMENT

strict_quotes

Strict quotes is off by default.

Strict quotes enforces that you version number must be quoted, like so: '0.01' and "0.01". 0.01 would in this case cause a violation. This would also go for any additional formats you could configure as valid using the "formats" parameter below.

[logicLAB::RequireVersionFormat]
strict_quotes = 1

ignore_quotes

Ignore quotes is on by default.

0.01, '0.01' and "0.01" would be interpreted as the same.

Disabling ignore quotes, would mean that: '0.01' and "0.01" would violate the default format since quotes are not specifed as part of the pattern. This would also go for any additional formats you could configure as valid using the "formats" parameter below.

[logicLAB::RequireVersionFormat]
ignore_quotes = 0

formats

If no formats are specified, the policy only enforces the default format mentioned in "DESCRIPTION" in combination with the above two configuration parameters of course.

[logicLAB::RequireVersionFormat]
formats = \A\d+\.\d+(_\d+)?\z || \Av\d+\.\d+\.\d+\z

DEPENDENCIES AND REQUIREMENTS

INCOMPATIBILITIES

This distribution has no known incompatibilities.

BUGS AND LIMITATIONS

I think it would be a good idea to ignore this particular version string and versions thereof:

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

I am however still undecided.
