MooseX::Types::Perl - Moose types that check against Perl syntax
use MooseX::Types::Perl qw(
This library provides Moose types for checking things (mostly
strings) against syntax that is, or is a reasonable subset of, Perl syntax.
These types are identical, and expect a string that could be a package or
module name. Thats 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.
The DistName type checks for a string like MooseX-Types-Perl, the sort of
thing used to name CPAN distributions. In general, its 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.
An Identifier is something that could be used as a
symbol name or other identifier (filehandle, directory handle, subroutine name,
format name, or label). Its what you put after the sigil (dollar sign, at
sign, percent sign) in a variable name. Generally, its 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.
SafeIdentifiers are just like Identifiers, but omit the single-letter variables
underscore, a, and b, as these have special significance.
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.
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.
