  Interface of interactive compiler to a client such as an IDE The model the presentation compiler consists of the following parts:

  unitOfFile: The map from sourcefiles to loaded units. A sourcefile/unit is loaded if it occurs in that map.

  manipulated by: removeUnitOf, reloadSources.

  A call to reloadSources will add the given sources to the loaded units, and start a new background compiler pass to compile all loaded units (with the indicated sources first). Each background compiler pass has its own typer run. The background compiler thread can be interrupted each time an AST node is completely typechecked in the following ways:

  1. by a new call to reloadSources. This starts a new background compiler pass with a new typer run. 2. by a call to askTypeTree. This starts a new typer run if the forceReload parameter = true 3. by a call to askTypeAt, askTypeCompletion, askScopeCompletion, askToDoFirst, askLinkPos, askLastType. 4. by raising an exception in the scheduler. 5. by passing a high-priority action wrapped in ask { ... }.

  Actions under 1-3 can themselves be interrupted if they involve typechecking AST nodes. High-priority actions under 5 cannot; they always run to completion. So these high-priority actions should to be short.

  Normally, an interrupted action continues after the interrupting action is finished. However, if the interrupting action created a new typer run, the interrupted action is aborted. If there's an outstanding response, it will be set to a Right value with a FreshRunReq exception.

   Deprecated

     (Since version 2.12.16) Use `formatString.format(value)` instead of `value.formatted(formatString)`, or use the `f""` string interpolator. In Java 15 and later, `formatted` resolves to the new method in String which has reversed parameters.
