What am I doing wrong with my .ycm_extra_conf.py?

Time：06-10

I have successfully installed the YouCompleteMe plugin for vim and it is already working, however, I cannot get it to work on an actual project. For some reason I cannot create a .ycm_extra_conf.py that actually works. To test it out I tried making a minimal project, i.e. I created ~/project with the following structure:

~/project
~/project/.ycm_extra_conf.py
~/project/code
~/project/code/example.cpp
~/project/include
~/project/include/example.hpp

Nothing fancy. When I edit example.cpp I try to #include "example.hpp" but it already fails there because ycm says it cannot find the file ('example.hpp' file not found [pp_file_not_found]). vim does find the .ycm_extra_conf.py file and it tries to load it, however, I am not sure whether it's working correctly.

The output from :YcmDebugInfo is:

My .ycm_extra_config.py looks like this:

import os
import ycm_core

flags = [
  '-Wall',
  '-O3',
  '-I../include',
  '-I./include',
  ]

def FlagsForFile(filename, ** kwargs):
  return
  {
    'flags': flags,
    'do_cache': True
  }

The output from the temporary log files is as follows. For /tmp/clangd_stderr2sp81d3p.log:

Any help would be appreciated!

CodePudding user response：

I found the answer. Basically my .ycm_extra_conf.py was borked. This one should work:

import os

flags = [
  '-Wall',
  '-O3',
  '-I../include',
  '-I./include',
  ]


def DirectoryOfThisScript():
  return os.path.dirname(os.path.abspath(__file__))


def Settings(** kwargs):
  return {
    'flags': flags,
    'include_paths_relative_to_dir': DirectoryOfThisScript()
  }

Basically the culprit was

return
{

instead of

return {

The latter one works, the former doesn't.

CodePudding user response：

In most cases, for most projects, we recommend:

  1. Using clangd
  2. Creating a compilation database
  3. NOT using a .ycm_extra_conf.py file at all.

This gives the best overall experience, including full-project analysis from clangd.
