|
// PowerPro utility, written by Bruce Switzer, is available from http://powerpro.webeddie.com
|
||
|
|
// PowerPro lexer is written by Christopher Bean (cbean@cb-software.net)
|
||
|
|
//
|
||
|
|
// Lexer code heavily borrowed from:
|
||
|
|
// LexAU3.cxx by Jos van der Zande
|
||
|
|
// LexCPP.cxx by Neil Hodgson
|
||
|
|
// LexVB.cxx by Neil Hodgson
|
||
|
|
//
|
||
|
|
// Changes:
|
||
|
|
// 2008-10-25 - Initial release
|
||
|
|
// 2008-10-26 - Changed how <name> is hilighted in 'function <name>' so that
|
||
|
|
// local isFunction = "" and local functions = "" don't get falsely highlighted
|
||
|
|
// 2008-12-14 - Added bounds checking for szKeyword and szDo
|
||
|
|
// - Replaced SetOfCharacters with CharacterSet
|
||
|
|
// - Made sure that CharacterSet::Contains is passed only positive values
|
||
|
|
// - Made sure that the return value of Accessor::SafeGetCharAt is positive before
|
||
|
|
// passsing to functions that require positive values like isspacechar()
|
||
|
|
// - Removed unused visibleChars processing from ColourisePowerProDoc()
|
||
|
|
// - Fixed bug with folding logic where line continuations didn't end where
|
||
|
|
// they were supposed to
|
||
|
|
// - Moved all helper functions to the top of the file
