Issue Details

I was wondering if clang-include-fixer (http://clang.llvm.org/extra/include-fixer.html) may be something worth integrating into YCM. As far as I can tell, the input to the program is similar to what YCM already uses for auto-completion and such (e.g. these databases that cmake produces).

Does that sound reasonable or does this not match the vision/spirit of this project?

[Valloric]

This is something we've been talking about for a bit. It seems like it would be a good fit for YCM, but it would require some careful design work. The whole symbol database thing complicates matters.

I want to ask another question : when I do this --"./install.py --all" , it takes so long to download Clang3.9.0 ,and I have to restart from 0 if I interrupt it .
Is there some way that can help me install it fast? Thank you !

[vheon]

@xxoolltt I don't think that your problem is relevant with this particular issue and it doesn't look like a real bug either so maybe the right place for this kinds of question is either the user group or gitter.

[bstaletic]

Clangd actually supports this.
