Update with https://www.scintilla.org/scintilla521.zip https://www.scintilla.org/lexilla515.zip - fix setting to bring Scintilla::PositionCR from ScintillaStructures.h inline with Sci_Position.h Sci_PositionCR - add workaround to enable lexer for searchResult commented out SCI_SETILEXER call on searchResult to get one result which is correctly handled by the lexer, added comment about the current problem with property @MarkingsStruct which seems to disappear after call to SCI_SETILEXER or CreateLexer - corrected usage of ObjC lexer - removed unnecessary filter stuff - use own sections for scintilla and lexilla build targets and allow parallel builds - as libscilex is no longer existing, changed to libscintilla - adapt makefiles and cmake - use VS2019 - started simple changes for createlexer adaptations, nullpointercheck missing on return of lexer name from deprecated LexerNameFromID -> undefined behaviour - movement from id -> lexer name, mostly done via LexerNameFromID + switching off corresponding compiler warning - changed to SCI_SETILEXER from SCI_SETLEXER, SCI_SETLEXERLANGUAGE needs to be corrected, see Scintilla5Migration.html - just commented out: SCI_LOADLEXERLIBRARY Fix #10504, close #11419
