Release 5.5.2 ( https://www.scintilla.org/scintilla552.zip ) Released 21 August 2024. Add SCI_SETCOPYSEPARATOR for separator between parts of a multiple selection when copied to the clipboard. Feature #1530. Add SCI_GETUNDOSEQUENCE to determine whether an undo sequence is active and its nesting depth. Add SCI_STYLESETSTRETCH to support condensed and expanded text styles. Add SCI_LINEINDENT and SCI_LINEDEDENT. Feature #1524. Fix bug on Cocoa where double-click stopped working when system had been running for a long time. On Cocoa implement more values of font weight and stretch. Release 5.4.0 ( https://www.scintilla.org/lexilla540.zip ) Released 21 August 2024. Inside Lexilla, LexerModule instances are now const. This will require changes to applications that modify Lexilla.cxx, which may be done to add custom lexers. Lexer added for TOML "toml". Bash: Handle backslash in heredoc delimiter. Issue #257. Progress: Fix lexing of nested comments. Pull request #258. Force lower-casing of case-insensitive keyword lists so keywords match in some lexers. Issue #259. Close #15564

// Lexer for PowerBasic by Roland Walter, roland@rowalt.de (for PowerBasic see www.powerbasic.com)
|
|
//
|
|
// Changes:
|
|
// 17.10.2003: Toggling of subs/functions now until next sub/function - this gives better results
|
|
// 29.10.2003: 1. Bug: Toggling didn't work for subs/functions added in editor
|
|
// 2. Own colors for PB constants and Inline Assembler SCE_B_CONSTANT and SCE_B_ASM
|
|
// 3. Several smaller syntax coloring improvements and speed optimizations
|
|
// 12.07.2004: 1. Toggling for macros added
|
|
// 2. Further folding speed optimitations (for people dealing with very large listings)
|
|
//
|
|
// Necessary changes for the PB lexer in Scintilla project:
|
|
// - In SciLexer.h and Scintilla.iface:
|
|
//
|
|
// #define SCLEX_POWERBASIC 51 //ID for PowerBasic lexer
|
|
// (...)
|
|
// #define SCE_B_DEFAULT 0 //in both VB and PB lexer
|
|
// #define SCE_B_COMMENT 1 //in both VB and PB lexer
|
|
// #define SCE_B_NUMBER 2 //in both VB and PB lexer
|
|
// #define SCE_B_KEYWORD 3 //in both VB and PB lexer
|
|
// #define SCE_B_STRING 4 //in both VB and PB lexer
|
|
// #define SCE_B_PREPROCESSOR 5 //VB lexer only, not in PB lexer
|
|
// #define SCE_B_OPERATOR 6 //in both VB and PB lexer
|
|
// #define SCE_B_IDENTIFIER 7 //in both VB and PB lexer
|
|
// #define SCE_B_DATE 8 //VB lexer only, not in PB lexer
|
|
// #define SCE_B_CONSTANT 13 //PB lexer only, not in VB lexer
|
|
// #define SCE_B_ASM 14 //PB lexer only, not in VB lexer
|
|
|
|
// - Statement added to KeyWords.cxx: 'LINK_LEXER(lmPB);'
|
|
// - Statement added to scintilla_vc6.mak: '$(DIR_O)\LexPB.obj: ...\src\LexPB.cxx $(LEX_HEADERS)'
