Adding the Clang analysis (clang ... --analyze) capabilities

[yh-sb]

Hi, I some times ago I had used SublimeText to work with C/C++ projects. To simplify my workflow I wrote extension which analyzed my opened files. It work pretty intellectually, see example below:

https://github.com/r44083/clang-linter

Now I have completely migrated to the VSCode and I was disappointed by the lack of such analysis. So I am going to implement this feature for VSCode.

I would like to integrate this into the "vscode-cpptools" extension. In this case Clang linter disables intellisense analyzer
Let me know if you agree to integrate my pool requests.

Clang analysis tool works really fast, reliably and deeply analyzes the code "on the fly".

Have you tried our linter? Add "C_Cpp.intelliSenseEngine": "Default" to your settings.json file.

We're not ruling out the possibility of supporting Clang as a linter at some future date, but it's not in our current roadmap. Our extension is not open source due to license restrictions in some of the code we use, so unfortunately there is no way for us to integrate any pull requests at this time.

@bobbrow Are you talking about the EDG C++ front end?

[bobbrow]

Yes, we use the EDG C++ front end.

@bobbrow ,

I'm thankful for all the work you're all putting in to help create and improve this wonderful program.

However, this isn't just about the fact that the default C_Cpp.intelliSenseEngine isn't working (see #746 ) or whether using clang will provide better results (even though I believe it will).

The fact of the matter is that clang is also used as collaborative "glue" in many projects, where the .clang_complete file allows us to share settings and flags across development environments.

If vscode can't support clang and it's .clang_complete convention, than collaboration is made that much harder.

I don't know if you code in C or C++ as much, but as a C developer I find clang integration to provide a major improvement to my workflow and I totally appreciate @r44083 's offer to fix this up.

This might just be my 2¢, but I would appreciate if you gave the matter some consideration.

Now, the cpptools extension works really well, so it isn't any need to extend it with clang mode support.
Thank you.
