MooseX::Types::Perl

NAME

MooseX::Types::Perl − Moose types that check against Perl syntax

VERSION

version 0.101341

SYNOPSIS

  use MooseX::Types::Perl qw(
    DistName
    ModuleName
    PackageName
    Identifier
    SafeIdentifier
    LaxVersionStr
    StrictVersionStr
    VersionObject
  );

DESCRIPTION

This library provides Moose types for checking things (mostly strings) against syntax that is, or is a reasonable subset of, Perl syntax.

TYPES

ModuleName
PackageName

These types are identical, and expect a string that could be a package or module name. That’s basically a bunch of identifiers stuck together with double-colons. One key quirk is that parts of the package name after the first may begin with digits.

The use of an apostrophe as a package separator is not permitted.

DistName
The DistName type checks for a string like "MooseX−Types−Perl", the sort of thing used to name CPAN distributions. In general, it’s like the more familiar ModuleName, but with hyphens instead of double-colons.

In reality, a few distribution names may not match this pattern -- most famously, "CGI.pm" is the name of the distribution that contains CGI . These exceptions are few and far between, and deciding what a "LaxDistName" type would look like has not seemed worth it, yet.

Identifier
An Identifier is something that could be used as a variable name. Generally, it’s a bunch of alphanumeric characters not starting with a digit.

Although Perl identifiers may contain non-ASCII characters in some circumstances, this type does not allow it. A "UnicodeIdentifier" type may be added in the future.

SafeIdentifier
SafeIdentifiers are just like Identifiers, but omit the single-letter variables underscore, a, and b, as these have special significance.

LaxVersionStr
StrictVersionStr

Lax and strict version strings use the is_lax and is_strict methods from "version" to check if the given string would be a valid lax or strict version. version::Internals covers the details but basically: lax versions are everything you may do, and strict omit many of the usages best avoided.

VersionObject
Just for good measure, this type is included to check if a value is a version object. Coercions from LaxVersionStr (and thus StrictVersionStr) are provided.
