# Repl

###

#### trait Repl extends ReplCore

Interface to the repl for use by the frontend (shell, the UI).

The interface should not depend on symbols and types (the compiler's internal state). At most, expose untyped trees and positions in addition to standard Java types. This decoupling would allow running the shell in a separate thread, or even in a separate process from the compiler. It should also be possible to write a new REPL frontend using this interface, and be compatible across minor compiler releases.

(The first iteration of this interface is only uses Positions and standard JVM types, but we could loosen that.)

### Abstract Value Members

1.  abstract def addUrlsToClassPath(urls: URL*): Unit

   Adds all specified jars to the compile and runtime classpaths.

   Adds all specified jars to the compile and runtime classpaths.

   urls

     The list of items to add to the compile and runtime classpaths.

   Note

     Currently only supports jars, not directories.

2.  abstract def bind(p: NamedParam): Result
3.  abstract def bind(name: String, boundType: String, value: Any, modifiers: List[String] = Nil): Result

   Bind a specified name to a specified value.

   Bind a specified name to a specified value. The name may later be used by expressions passed to interpret.

   name

     the variable name to bind

   boundType

     the type of the variable, as a string

   value

     the object value to bind to it

   returns

     an indication of whether the binding succeeded

   This instance is no longer needed, so release any resources it is using. The reporter's output gets flushed.

8.  abstract def compileSources(sources: SourceFile*): Boolean

   Compile an nsc SourceFile.

   Compile an nsc SourceFile. Returns true if there are no compilation errors, or false otherwise.

9.  abstract def compileString(code: String): Boolean

    Interpret one line of input.

    Interpret one line of input. All feedback, including parse errors and evaluation results, are printed via the supplied compiler's reporter. Values defined are available for future interpreted strings.

    The return value is whether the line was interpreter successfully, e.g. that there were no parse errors.
