Set this to the absolute path to the folder (NOT the file!) containing the

compile_commands.json file to use that instead of 'flags'. See here for

more details: http://clang.llvm.org/docs/JSONCompilationDatabase.html

Most projects will NOT need to set this to anything; you can just change the

'flags' list of compilation flags. Notice that YCM itself uses that approach.

compilation_database_folder = ''

if os.path.exists( compilation_database_folder ): database = ycm_core.CompilationDatabase( compilation_database_folder ) else: database = None

SOURCE_EXTENSIONS = [ '.cpp', '.cxx', '.cc', '.c', '.m', '.mm' ]

    new_flags.append( new_flag )
return new_flags

def IsHeaderFile( filename ): extension = os.path.splitext( filename )[ 1 ] return extension in [ '.h', '.hxx', '.hpp', '.hh' ]

def GetCompilationInfoForFile( filename ):

The compilation_commands.json file generated by CMake does not have entries

for header files. So we do our best by asking the db for flags for a

corresponding source file, if any. If one exists, the flags for that file

should be good enough.

if IsHeaderFile( filename ): basename = os.path.splitext( filename )[ 0 ] for extension in SOURCE_EXTENSIONS: replacement_file = basename + extension if os.path.exists( replacement_file ): compilation_info = database.GetCompilationInfoForFile( replacement_file ) if compilation_info.compiler_flags_: return compilation_info return None return database.GetCompilationInfoForFile( filename )
