Vim Plugin YouCompleteMe add header directory recursively - vim

Question

I am trying to configure the vim Plugin "YouCompleteMe". My C++ project consists of many header files, which are spread all over the directory tree. In order to add header directories I have to add them in the ".ycm_extra_conf.py".
Excerpt:
'-I',
'./src/base/utils',
'-I',
'./src/base/modules',
But something like this does not work:
'-I',
'./src/base/*',
Is there a way to tell YCM to recursively search for header files?
Thank you.

Answer 1

I have added a new syntax -ISUB to include all sub-directories.
e.g.
"-ISUB./Pods/Headers/Public"
full .ycm_extra_conf.py here
import os
import ycm_core
flags = [
#custom definition, include subfolders
'-ISUB./Pods/Headers/Public',
'-I./Pod/Classes',
]
def Subdirectories(directory):
res = []
for path, subdirs, files in os.walk(directory):
for name in subdirs:
item = os.path.join(path, name)
res.append(item)
return res
def IncludeFlagsOfSubdirectory( flags, working_directory ):
if not working_directory:
return list( flags )
new_flags = []
make_next_include_subdir = False
path_flags = [ '-ISUB']
for flag in flags:
# include the directory of flag as well
new_flag = [flag.replace('-ISUB', '-I')]
if make_next_include_subdir:
make_next_include_subdir = False
for subdir in Subdirectories(os.path.join(working_directory, flag)):
new_flag.append('-I')
new_flag.append(subdir)
for path_flag in path_flags:
if flag == path_flag:
make_next_include_subdir = True
break
if flag.startswith( path_flag ):
path = flag[ len( path_flag ): ]
for subdir in Subdirectories(os.path.join(working_directory, path)):
new_flag.append('-I' + subdir)
break
new_flags =new_flags + new_flag
return new_flags

I had the same problem so I created a function that do it.
add the following to your ".ycm_extra_conf.py" right after the flags list:
import glob
flagsRec=['/opt/e17/include/*']
def AddDirsRecursively( flagsRec ):
global flags
new_flags = []
for flag in flagsRec:
for d in glob.glob(flag) :
if os.path.isdir(d):
new_flags.append('-I')
new_flags.append(d)
flags += new_flags
AddDirsRecursively( flagsRec )
where "flagsRec" is the list of dirs(regular expressions) you want to traverse and add to "flags"
