Functions

fun addDeclaration(declaration: A_Phrase): A_Phrase?

Attempt to add the declaration to the compiler scope information within the client data stored in the current fiber. If there is already a declaration by that name, return it; otherwise return null.

createFiber

fun createFiber( resultType: A_Type, runtime: AvailRuntime, loader: AvailLoader?, textInterface: TextInterface, priority: Int, setup: A_Fiber.() -> Unit = { }, nameSupplier: () -> A_String): A_Fiber

Construct an unstarted fiber with the specified result type, name supplier, and AvailLoader. The priority is initially set to loaderPriority.

currentFiber

fun currentFiber(): A_Fiber

Answer the fiber currently bound to the current Interpreter.

lookupBindingOrNull

fun lookupBindingOrNull(name: A_String): A_Phrase?

Look up the declaration with the given name in the current compiler scope. This information is associated with the current Interpreter, and therefore the fiber that it is executing. If no such binding exists, answer null. The module scope is not consulted by this mechanism.

newFiber

fun newFiber( resultType: A_Type, runtime: AvailRuntime, textInterface: TextInterface, priority: Int, setup: A_Fiber.() -> Unit = { }, nameSupplier: () -> A_String): A_Fiber

Construct an unstarted fiber with the specified result type and initial priority.

newLoaderFiber

fun newLoaderFiber( resultType: A_Type, loader: AvailLoader, nameSupplier: () -> A_String): A_Fiber

Construct an unstarted fiber with the specified result type and AvailLoader. The priority is initially set to loaderPriority.

newStylerFiber

fun newStylerFiber(loader: AvailLoader, nameSupplier: () -> A_String): A_Fiber

Construct an unstarted fiber with the specified AvailLoader, for the purpose of styling tokens and phrases. Such a fiber is the only place that styling is allowed. Fibers launched from this fiber also allow styling, but they should be joined by this fiber to ensure they are not making changes after styling is supposed to have completed. The priority is initially set to loaderPriority.
