Instance Method Detail

def enable(*, in caps : CapabilityCollection) #
Description copied from module Novika::Resolver::Resolution::Dependency

If this dependency is allowed?, enables it in the given capability collection caps.


def envelope(container : RunnableContainer) #
Description copied from module Novika::Resolver::Resolution::Dependency::DefaultPrompt

Returns the string representation of this dependency's envelope (its container so to speak). The runtime (not specialize-time!) container is provided as a fallback option (albeit a very bad one).


def id #

Returns the id of this shared object.

The id is made by taking the stem of the path to the object and stripping it of the lib prefix, if it has one. For example, given /lib/libmath.so or /lib/math.so, the id would be math in both cases.


def label(server : PermissionServer) : String #
Description copied from module Novika::Resolver::Resolution::Dependency::DefaultPrompt

Returns a user-friendly string representation of this dependency. The returned string should be suitable for displaying to the user in a prompt.

server is the permission server that will then use the label in one way or another. You may also choose to derive the label with server's help.


def signature(container : RunnableContainer) : Signature #
Description copied from module Novika::Resolver::Resolution::Dependency

Returns the signature of this dependency which can be used to identify it, most notably in the 'permissions' file.

container, assumed to contain this dependency, may be used to derive the signature.


def specialize(root : RunnableRoot, container : RunnableContainer) #
Description copied from class Novika::Resolver::Runnable

Further specializes this runnable. Appends the specialized runnable to (or interacts in some other way with) container. The latter is assumed to be incomplete (or partially complete, which is really the same thing).

root is the runnable root object. It is mainly used for flags and thorough rewriting.
