Code folding didn't work as expected in directives and block comment

[LeThiHyVong]

In my code there are many places look like this

#if SOME_CONST_EXP
;//       some code
#else
      // some code
#endif

or

if SOME_CONST_EXP
;//      some code
#endif

or

/*************************************
//
//
//
//
*************************************/

EDIT (@bobbrow): (inserting request for folding on multiple consecutive single-line comments from #1443)

// Comment
// Comment
// Comment
// Comment

The code folding only work correctly between #else and #endif.
From #if to next directive (#else in 1st case or #endif in 2nd case), if all line is started with ';//', the code folding didn't work.
From #endif to next directive, it automatically group the code outside the directive for all time.
The coding folder didn't work for 3rd, too.

System spec:

• Windows 7 SP1 x86
• VSCode 1.7.2
• Plugin 0.9.3

Please correct this.

Yes, the code folding is buggy, but it's not a bug with the C/C++ extension. We don't implement any code folding. Can you move this to the vscode team?

[sean-mcmanus]

Actually, it sounds like the folding behavior you are seeing is "by design". The fixing of this is being tracked at microsoft/vscode#3422 . VS Code implements the folding behavior and there isn't an API yet to allow language-aware folding.

According to microsoft/vscode#3422 (comment), please re-open this issue.
Thanks.

This would be a great feature and bug fix to have and essential for the code base I work on which relies on many preprocessor switches to support multiple builds. Diming the inactive code with "C_Cpp.dimInactiveRegions": true is a good first step, but having the ability to collapse and hide the inactive code region altogether is even better.
Eclipse even has the option to collapse inactive regions by default when opening a file by default.

Here's a screenshot from 0.17.4 showing the various issues with folding currently.
