#target_version_already_installed?(current_version, target_version) ⇒ Boolean

This function will eventually be deprecated in favour of the below version_equals function.

#version_compare(v1, v2) ⇒ Object

This function compares two version numbers and returns 'spaceship operator' style results, ie: if v1 < v2 then return -1 if v1 = v2 then return 0 if v1 > v2 then return 1 if v1 and v2 are not comparable then return nil

By default, this function will use Gem::Version comparison. Subclasses can reimplement this method for package-management system specific versions.

(In other words, pull requests to introduce domain specific mangling of versions into this method will be closed -- that logic must go into the subclass -- we understand that this is far from perfect but it is a better default than outright buggy things like v1.to_f <=> v2.to_f)

end

#version_requirement_satisfied?(current_version, new_version) ⇒ Boolean

Check the current_version against the new_resource.version, possibly using fuzzy matching criteria.

Subclasses MAY override this to provide fuzzy matching on the resource ('>=' and '~>' stuff)

version_satisfied_by?(version, constraint) might be a better name to make this generic.

Returns:

  • (Boolean)
