https://www.scintilla.org/scintilla534.zip Released 8 March 2023. Add multithreaded wrap to significantly improve performance of wrapping large files. More typesafe bindings of *Full APIs in ScintillaCall. Feature #1477. Fix overlapping of text with line end wrap marker. Bug #2378. Fix clipping of line end wrap symbol for SC_WRAPVISUALFLAGLOC_END_BY_TEXT. Where a multi-byte character contains multiple styles, display each byte as a representation. This makes it easier to see and fix lexers that change styles mid-character, commonly because they use fixed size buffers. Fix a potential crash with autocompletion list fill-ups where a SCN_CHARADDED handler retriggered an autocompletion list, but with no items that match the typed character. lexilla523 Released 8 March 2023. Add scripts/PromoteNew.bat script to promote .new files after checking. Makefile: Remove 1024-byte line length limit.. Ruby: Add new lexical classes for % literals SCE_RB_STRING_W (%w non-interpolable string array), SCE_RB_STRING_I (%i non-interpolable symbol array), SCE_RB_STRING_QI (%I interpolable symbol array), and SCE_RB_STRING_QS (%s symbol). Issue #124. Ruby: Disambiguate %= which may be a quote or modulo assignment. Issue #124, Bug #1255, Bug #2182. Ruby: Fix additional fold level for single character in SCE_RB_STRING_QW. Issue #132. Ruby: Set SCE_RB_HERE_QQ for unquoted and double-quoted heredocs and SCE_RB_HERE_QX for backticks-quoted heredocs. Issue #134. Ruby: Recognise #{} inside SCE_RB_HERE_QQ and SCE_RB_HERE_QX. Issue #134. Ruby: Improve regex and heredoc recognition. Issue #136. Ruby: Highlight #@, #@@ and #$ style interpolation. Issue #140. Ruby: Fix folding for multiple heredocs started on one line. Fix folding when there is a space after heredoc opening delimiter. Issue #135. YAML: Remove 1024-byte line length limit. https://www.scintilla.org/lexilla524.zip Released 13 March 2023. C++: Fix failure to recognize keywords containing upper case. Issue #149. GDScript: Support % and $ node paths. Issue #145, Pull request #146. Close #13338
