    08. Install YouCompleMe

    https://github.com/ycm-core/YouCompleteMe

    • Install dependencies
    sudo apt install gcc g++ cmake make build-essential vim-nox python3-dev
    • Add to your .vimrc: Plug 'ycm-core/YouCompleteMe'
    • Complete the installation:
    cd .vim/plugged/YouCompleteMe/
python3 install.py --clangd-completer # Only C/C++
# python3 install.py --all # Need Go and NPM:
# sudo apt install golang npm
    • Save this file: .ycm_extra_conf.py in ~/.vim/.ycm_extra_conf.py
    • Add this for others libs:

      vim ~/vim/.ycm_extra_conf.py

    '-I/usr/include/gtkmm-3.0',
'-I./',
'-I/usr/include'

    09. Settings to YouCompleteMe

    vim test.cpp

    I came testing.cpp

    • By typing #include <iostream> and #include <vector> it will autocomplete! If not, add this line to your ~/.vimrc
    let g:ycm_global_ycm_extra_conf = '~/.vim/.ycm_extra_conf.py'
    • Removing the drop-down window when using the autocomplete, add this line:
    set completeopt-=preview
    • To disable write-time diagnostics:
    let g:ycm_show_diagnostics_ui = 0

    Compiling: :terminal and g++ test.cpp, to exit the terminal: exit.

    10 Add Auto-pairs

    https://github.com/jiangmiao/auto-pairs

    Plug 'jiangmiao/auto-pairs'

    11. Installing the ccls Language Server

    https://github.com/MaskRay/ccls

    sudo apt install ccls

    Copy this code and paste into your ~/.vimrc

    let g:ycm_language_server =
  \ [{
  \   'name': 'ccls',
  \   'cmdline': [ 'ccls' ],
  \   'filetypes': [ 'c', 'cpp', 'cc', 'h', 'hpp' ],
  \   'project_root_files': [ '.ccls-root', 'compile_commands.json' ]
  \ }]

    Note that when autocompleting now it automatically adds a header, if you don’t want that to happen, add this line to your .vimrc: let g:ycm_clangd_args=['--header-insertion=never']

    Plug 'SirVer/ultisnips'
Plug 'honza/vim-snippets'

let g:ycm_key_list_previous_completion = ['<C-p>', '<Up>']
let g:SuperTabDefaultCompletionType = '<C-n>'
let g:UltiSnipsExpandTrigger = "<tab>"
let g:UltiSnipsJumpForwardTrigger = "<tab>"
let g:UltiSnipsJumpBackwardTrigger = "<s-tab>"
