Title: Lexer bug in macros
Post by: carra on July 11, 2012, 09:30:48 am
I saw this lexer problem quite a bit ago, but I had forgotten to post it until now. As you may know, preprocessor macros admit embedded comments, very useful to clarify big multiline macros. Let's take this simple iterator macro as an example:

Code
#define ITER_C_STR( chars )  for( /* empty */; *(chars); (chars)++ )

If you view this macro in C::B editor, it will highlight it as a macro only up to the comment, and all the rest is colored as if it was normal code and not part of the macro. It seems to be only a lexer issue, since it will compile OK and the macro is even added to autocompletion list correctly.

Confirmed on Linux + r8043...

Please try in SciTE (http://www.scintilla.org/SciTE.html) and if its the same there, file a bug report to the scintilla guys.

I tried with SciTE 3.20 and the bug is still there. There is a bug listed in scintilla about this (ID: 3487406). BUT, as you see here: http://sourceforge.net/tracker/index.php?func=detail&aid=3487406&group_id=2439&atid=102439

... they report it as already fixed ??
Well, it clearly isn't.

The fix was committed on Date: 2012-06-25 00:25:59 PDT.

Likely you tested code written before that.

It is, and if you compile C::B yourself, it will be there, too. Note what stahta01 said:

SciTE 3.2.0 was released before that date. so most likely next SciTE will have this fixed, too (just as the next C::B nightly).

I see, so that was it. Well, in this case I have nothing left to complain here! :) I'll check this in next nightly (since I don't compile C::B)
