abstract class Novika::Resolver::Slot

Overview

Base class of ScriptsSlot (known to the user as *), SubtreeSlot (known to the user as **), and ChildSlot (<>).

Slots act as mere sentinels (or placeholders). They get #replaced with runnable containers that hold the appropriate runnables during postprocessing of the manifest file, provided the latter has some slots to begin with.

The use of slot literals *, **, and <> is only allowed inside manifest files.

Even though using several *s is allowed, it is pointless to do so because the first * (or ** for that matter) will 'consume' all remaining file system entries, leaving none to the second, third, etc. * or **.

Instance Method Detail

abstract def replace(root : RunnableRoot, group : RunnableGroup, manifest : Manifest::Present, population : RunnableContainer, container : RunnableContainer) : RunnableContainer #

Replaces any occurences of this slot in container with a container holding the runnables this slot stands for.

manifest is the manifest that contains this slot.

group is the RunnableGroup of the manifest that contains this slot.

Returns the next population container.
