Eric Promislow:
But it would be cool if LineState
was defined as union{int; void*}, and scintilla provided Finalizers
for each line and the buffer as a whole.
I would have expected a buffer init / finalize would be sufficient
as the lexer can drop information from lines after any modification
since it is called to lex from there on. A lexer may decide to use a
compact format like [{lineNumber, hereDocDelimiter}, ...] rather than
one int / pointer per line. For the API, there could be a
SCI_SETLEXERDATA(sptr_t), SCI_GETLEXERDATA() -> sptr_t, Accessor
gains methods for these, LexerModule gains an entry point
ControlFn(int actionCode, sptr_t arg) actionCode is (LEXER_INIT,
LEXER_FINALIZE, ...).
To minimize changes the ControlFn isn't really needed as the lexer
could notice that LEXERDATA is NULL, and could interpret a call to lex
from 0 to 0 as a signal to deallocate.
