is_alpha#

Tell whether a version marks an alpha / developer release.

תקציר#

if ($v->is_alpha) { ... }

An alpha version is any version whose source string contained an underscore, e.g. "1.02_03" or "v1.2_3". CPAN uses the underscore to mark a non-indexed developer release.

מה מוחזר#

A boolean: 1 if the version’s source string contained an underscore, the empty string otherwise.
