request to improve: auto find clang library and clang database

[butterflyfish]

Currently, it have to set lib clang and header path. how about trying to find automatically and then use fallback setting ?

Try to find compiler database also and then use fallback setting. It does not need to tell where is compiler database when using YCM.

@butterflyfish Sorry for late reply :(

Yes, users will need to set it explicitly. YCM and clang_complete seem to automatically parse clang headers. but maybe YCM is parse C++ side(?), and clang_complete seems to decrease a little performance.

However, It is a good idea to fall back to if not set clang header path. I'll implement later.

This meaning of compile_commands.json support? If true, it has already been implemented.

let g:deoplete#sources#clang#clang_complete_database = '/path/to/neovim/build'

but this behavior is too slow.. I am considering a faster methods. But I do not want to use the C++ (I do not write C, C++ :scream: ). Pure Python? or use Numpy? or use the shared library written Go? or etc...

Also, planned https://github.com/zchee/deoplete-clang/issues/11.

Sorry for If my understanding is mistaken :(

thx. that's what I want. Only hope to simplify configuration.

@butterflyfish Thanks. I considering it.

I will implement this feature(auto find clang library and header).
