Existing editor rules cover +only a subset of its syntax: - Uppercase, case-sensitive keywords; ASCII `<-` assignment; `//` comments. - Native C aliases C_INT/C_CHAR/C_STRING/C_DOUBLE and the C_TYPE import keyword use type scopes. C_TYPE's quoted expression remains a string, and casts use ordinary parentheses. `TYPE Name = C_TYPE("...")` is a single-line alias declaration, so it does not open an indentation block. -- Double-quoted strings and single-quoted characters have no escapes or multiline - continuation. The compiler accepts `'''` as a quote character literal. +- The compiler decodes C++17 byte escapes and Unicode escapes in literals; strings + encode Unicode as UTF-8 and CHAR Unicode escapes must be ASCII. The plugin's + grammar and quote masking still ignore escapes and retain legacy `'''` handling; + the compiler now requires an escaped quote character (`'\''`). Neither supports + multiline literal continuation. - Blocks: IF/THEN/ELSE/ENDIF, WHILE/DO/ENDWHILE, REPEAT/UNTIL, FOR/NEXT, FUNCTION/ENDFUNCTION, PROCEDURE/ENDPROCEDURE, record TYPE/ENDTYPE and TRY/CATCH/ENDTRY. CATCH aligns with TRY and starts another indented body; ENDTRY closes the block. Bare THROW does not change indentation depth. - Separate THEN and DO lines activate the pending block once.

Language defaults use real Tabs, display width 4, disabled indentation detection, full automatic indentation, on-type formatting and native bracket pair colors. |
