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