// Scintilla source code edit control
// @file LexAU3.cxx
// Lexer for AutoIt3 http://www.hiddensoft.com/autoit3
// by Jos van der Zande, jvdzande@yahoo.com
//
// Changes:
// March 28, 2004 - Added the standard Folding code
// April 21, 2004 - Added Preprosessor Table + Syntax Highlighting
// Fixed Number highlighting
// Changed default isoperator to IsAOperator to have a better match to AutoIt3
// Fixed "#comments_start" -> "#comments-start"
// Fixed "#comments_end" -> "#comments-end"
// Fixed Sendkeys in Strings when not terminated with }
// Added support for Sendkey strings that have second parameter e.g. {UP 5} or {a down}
// April 26, 2004 - Fixed # pre-processor statement inside of comment block would invalidly change the color.
// Added logic for #include <xyz.au3> to treat the <> as string
// Added underscore to IsAOperator.
// May 17, 2004 - Changed the folding logic from indent to keyword folding.
// Added Folding logic for blocks of single-commentlines or commentblock.
// triggered by: fold.comment=1
// Added Folding logic for preprocessor blocks triggered by fold.preprocessor=1
// Added Special for #region - #endregion syntax highlight and folding.
// May 30, 2004 - Fixed issue with continuation lines on If statements.
// June 5, 2004 - Added comma to Operators for better readability.
// Added fold.compact support set with fold.compact=1
// Changed folding inside of #cs-#ce. Default is no keyword folding inside comment blocks when fold.comment=1
// it will now only happen when fold.comment=2.
// Sep 5, 2004 - Added logic to handle colourizing words on the last line.
// Typed Characters now show as "default" till they match any table.
// Oct 10, 2004 - Added logic to show Comments in "Special" directives.
// Nov 1, 2004 - Added better testing for Numbers supporting x and e notation.
// Nov 28, 2004 - Added logic to handle continuation lines for syntax highlighting.
// Jan 10, 2005 - Added Abbreviations Keyword used for expansion
// Mar 24, 2005 - Updated Abbreviations Keywords to fix when followed by Operator.
// Apr 18, 2005 - Updated #CE/#Comment-End logic to take a linecomment ";" into account
// - Added folding support for With...EndWith
// - Added support for a DOT in variable names
// - Fixed Underscore in CommentBlock
// May 23, 2005 - Fixed the SentKey lexing in case of a missing }
// Aug 11, 2005 - Fixed possible bug with s_save length > 100.
// Aug 23, 2005 - Added Switch/endswitch support to the folding logic.
// Sep 27, 2005 - Fixed the SentKey lexing logic in case of multiple sentkeys.
// Mar 12, 2006 - Fixed issue with <> coloring as String in stead of Operator in rare occasions.
// Apr 8, 2006 - Added support for AutoIt3 Standard UDF library (SCE_AU3_UDF)
// Mar 9, 2007 - Fixed bug with + following a String getting the wrong Color.
// Jun 20, 2007 - Fixed Commentblock issue when LF's are used as EOL.
// Jul 26, 2007 - Fixed #endregion undetected bug.
