VERSION
version 0.101340
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.
