Release 5.5.3 (https://www.scintilla.org/scintilla553.zip) Released 19 October 2024. On Win32 change direction of horizontal mouse wheel and touchpad scrolling to match other applications. Bug #2449. Release 5.4.1 (https://www.scintilla.org/lexilla541.zip) Released 19 October 2024. Lexer added for Dart "dart". Pull request #265, Pull request #275. Lexer added for troff / nroff "troff". Pull request #264. Lexer added for Zig "zig". Pull request #267. C++: Fix crash for empty documentation comment keyword where '<' occurs at line end. F#: Include EOLs in the style range of SCE_FSHARP_COMMENTLINE. Stabilizes EOL detection when folding line comment groups. Issue #276. F#: Fix per-line folding in F# documents. Issue #277. HTML: Improve SGML/DTD lexing. Don't terminate SGML when > inside quoted string. Lex both [ and ] as SCE_H_SGML_DEFAULT. Nested sections handled instead of switching to SCE_H_SGML_ERROR. Issue #272. JavaScript: New SCE_HJ_TEMPLATELITERAL and SCE_HJA_TEMPLATELITERAL styles for template literals when lexer is hypertext, or xml. Issue #280. PHP: Fix failure to recognize PHP start "<?php' at end of document. Caused by not capping retrieval range at document end causing no text to be retrieved. Issue #269. Smalltalk: Fix scaled decimal numbers without decimal separator. Pull request #274. Fix #15228, fix #15368, fix #15650, close #15717

// A simple lexer

/** @file SimpleLexer.cxx

|
** A lexer that follows the Lexilla protocol to allow it to be used from Lexilla clients like SciTE.

** The lexer applies alternating styles (0,1) to bytes of the text.
