Public Methods

Method	Description
CommandLine ( ) : System
GetGlobals ( string name ) : IList
GetMemberNames ( string code ) : IList
Run ( ScriptEngine engine, IConsole console, ConsoleOptions options ) : void	Executes the comand line - depending upon the options provided we will either run a single file, a single command, or enter the interactive loop.
Terminate ( int exitCode ) : void

Protected Methods

Method	Description
CreateCommandDispatcher ( ) : ICommandDispatcher
CreateScope ( ) : Scope
ExecuteCommand ( ScriptSource source ) : object
ExecuteCommand ( string command ) : void
GetCommandProperties ( string code ) : ScriptCodeParseResult
GetNextAutoIndentSize ( string text ) : int	Gets the next level for auto-indentation
GetOutputWriter ( bool isErrorOutput ) : TextWriter
Initialize ( ) : void
PrintLogo ( ) : void
ReadLine ( int autoIndentSize ) : string
ReadStatement ( bool &continueInteraction ) : string	Read a statement, which can potentially be a multiple-line statement suite (like a class declaration).
Run ( ) : int	Runs the command line. Languages can override this to provide custom behavior other than: 1. Running a single command 2. Running a file 3. Entering the interactive console loop.
RunCommand ( string command ) : int
RunFile ( string fileName ) : int
RunInteractive ( ) : int	Starts the interactive loop. Performs any initialization necessary before starting the loop and then calls RunInteractiveLoop to start the loop. Returns the exit code when the interactive loop is completed.
TryInteractiveAction ( ) : int?	Attempts to run a single interaction and handle any language-specific exceptions. Base classes can override this and call the base implementation surrounded with their own exception handling. Returns null if successful and execution should continue, or an exit code.
UnhandledException ( Exception e ) : void

Private Methods

Method	Description
IsFatalException ( Exception e ) : bool
RunFile ( ScriptSource source ) : int
RunInteractiveLoop ( ) : int
RunOneInteraction ( ) : int?	Parses a single interactive command or a set of statements and executes it. Returns null if successful and execution should continue, or the appropiate exit code. We check if the code read is an interactive command or statements is by checking for NewLine If the code contains NewLine, it's a set of statements (most probably from SendToConsole) If the code does not contain a NewLine, it's an interactive command typed by the user at the prompt
Shutdown ( ) : void
TreatAsBlankLine ( string line, int autoIndentSize ) : bool	Private helper function to see if we should treat the current input as a blank link. We do this if we only have auto-indent text.
