How to recursively add include folders?

[Ronnie Zheng]

Hi all,

When setup large C++ project in vi with YCM, if the headers files are in various sub-folders of the root folder, is there a way to add all of them to the include path of clang with one single -I statement in .ycm_extra_conf.py? Otherwise it is impossible to add them one bye one...

e.g. -I/home/xxx/topdir/** will be expended to all subdir in the topdir .

Regards

Ronnie.

In .ycm_extra_conf.py you define a function FlagsForFile, which returns an object with a 'flags' field. You can use some python code to populate is, have you considered this option?

Hi Ronnie,

I use the following in my .ycm_extra_conf.py, right after the flags section:

def find_git_root():

    pipe = subprocess.Popen(['git', 'rev-parse', '--show-toplevel'],

                            stdout=subprocess.PIPE)

    repo_dir = pipe.communicate()[0].rstrip().decode('utf-8')

    return repo_dir

def gen_recursive_include_path(dir):

    subdirs = [x[0] for x in os.walk(dir) if "CMake" not in x[0]]

    include_path = []

    for x in subdirs:

        include_path.extend(['-I', x])

    return include_path

flags = flags + gen_recursive_include_path(find_git_root() + '/src')

flags = flags + gen_recursive_include_path(find_git_root() + '/build/src')

It automatically adds all subdirs in the project to the include path.
