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.
