SysBugSignal: SIGNAL [systemError: BOOLEAN];


SysBug: PROCEDURE [exception: Exception _ nil, message: STRING _ NIL];
-- Called when Laurel cannot proceed due to internal or user errors.  When exception = nil
--   and message = NIL, assumes that an internal error has occurred.  Otherwise,
--   assumes that a user error has occurred.


DisplayException: PROCEDURE [exception: Exception _ nil];
-- Displays error messages in the exceptions region.


DisplayExceptionString: PROCEDURE [string: STRING];
-- Displays error string in the exceptions region.


DisplayExceptionLine: PROCEDURE [exception: Exception,
	lineNumber: CARDINAL];
-- Maps exception to its string and displays it on lineNumber of the exceptions region.


DisplayExceptionStringOnLine: PROCEDURE [exceptionString: STRING,
	lineNumber: CARDINAL];
-- Displays exceptionString on lineNumber of the exceptions region.


DisplayExceptionOrStringOnLine: PROCEDURE [exception: Exception, string: STRING,
	lineNumber: CARDINAL];
-- Displays exception if non-nil, otherwise string on lineNumber of the exceptions region.


DisplayBothExceptionLines: PROCEDURE [string1: STRING, exception1: Exception,
	string2: STRING, exception2: Exception, flash: BOOLEAN _ TRUE];
-- Displays exception messages.  Will use string1 if non-NIL and non-zero length, exception1
--   otherwise. Mutatis mutandis for string2.  If flash, then will flash exceptions region.


AppendStringToExceptionLine: PROCEDURE [s: STRING, line: CARDINAL];
-- Appends s to the text already on line.  May signal ExceptionLineOverflow with parameter
--   i being the index of the first character in s that doesn't fit on line.


AppendExceptionToExceptionLine: PROCEDURE [exception: Exception, line: CARDINAL];
-- Appends exception to the text already on line.  May signal ExceptionLineOverflow with
--   parameter i being the the index of the first character in exception that doesn't fit on line.


AppendDecimalToExceptionLine: PROCEDURE [n: CARDINAL, line: CARDINAL];
-- Appends n to the text already on line.  May signal ExceptionLineOverflow with parameter
--   i being the index of the first character in n that doesn't fit on line.


ExceptionLineOverflow: ERROR [i: CARDINAL];
-- Raised by AppendStringToExceptionLine (see above).


FlashExceptionsRegion: PROCEDURE;
-- Flashes a rectangle within the exceptions region.


ClearExceptionsRegion: PROCEDURE = INLINE
-- Clears the exceptions region only if needed.
{IF exceptionRegionDirty THEN RealClearExceptionsRegion[]};


exceptionRegionDirty: BOOLEAN;

RealClearExceptionsRegion: PROCEDURE;
-- Really clears the entire text area of the exceptions region.


ExceptionType: TYPE = {Laurel, LaurelX};


InitializeExceptions: PROCEDURE;
-- Must be called before BringInLaurelState.


SetUpExceptionTable: PROCEDURE;
-- Establishes proper table for Get/Append ExceptionString.


GetExceptionString: PROCEDURE [exception: Exception, exceptionString: STRING];
-- Fills in caller supplied exceptionString with text corresponding to exception.


AppendExceptionString: PROCEDURE [exception: Exception, exceptionString: STRING];
-- Appends text corresponding to exception to end of caller supplied exceptionString.


SetExternalExceptionProc: PUBLIC PROCEDURE [proc: PROCEDURE [STRING] ];
-- Allows a loaded program to redirect exception output.  To cancel, call this procedure with
--   argument NIL.
