Highlighting of `#endif` after `#define` with trailing comment #11178

Closed damerste closed 1 year ago

damerste commented 1 year ago

Environment

Bug Summary and Steps to Reproduce

Bug Summary:

If a #define inside an #if block is followed by a trailing comment, the highlighting of the #endif is erroneous (red instead of magenta) if language mode is set to C. Problems are still empty, so it's obviously only a highlighting issue.

#ifdef __GNUC__
  #define TEST 1 // Just a trailing comment
#endif

Setting language mode to C++, or writing the comment as /* */ makes the error disappear.

Expected behavior:

With cStandard set to c99 or higher, the highlighter should cope with double-slash comments.

Hi @damerste . I can reproduce this issue, but it repros even without the C/C++ Extension installed.

The C/C++ Extension provides semantic colorization. VS Code itself provides syntax/lexical colorization, using something called a TextMate grammar. VS Code is currently ingesting the TextMate grammar for C and C++ contributed by the following repo: https://github.com/jeff-hykin/better-cpp-syntax

I'd suggest opening an issue either in that repo or in the VS Code repo.

Closing this issue as external.
