YouCompleteMe and Syntastic compatibility?

Question

What I want to do is to have YouCompleteMe do completions and Syntastic to check for errors but it looks that doesn\'t go together.

When YouCompleteMe is disabled then S

Answer 1

Here is my modified version of .vimrc (only YCM settings) file so that now with these settings YouCompleteMe works with all the features + I do not need any of syntastic features any more since it's not needed, except only 2, and that's auto opening of location list and auto jumping to the errors.

let g:ycm_register_as_syntastic_checker = 1 "default 1
let g:Show_diagnostics_ui = 1 "default 1

"will put icons in Vim's gutter on lines that have a diagnostic set.
"Turning this off will also turn off the YcmErrorLine and YcmWarningLine
"highlighting
let g:ycm_enable_diagnostic_signs = 1
let g:ycm_enable_diagnostic_highlighting = 0
let g:ycm_always_populate_location_list = 1 "default 0
let g:ycm_open_loclist_on_ycm_diags = 1 "default 1


let g:ycm_complete_in_strings = 1 "default 1

let g:ycm_server_use_vim_stdout = 0 "default 0 (logging to console)
let g:ycm_server_log_level = 'info' "default info


let g:ycm_global_ycm_extra_conf = '~/.ycm_extra_conf.py'  "where to search for .ycm_extra_conf.py if not found
let g:ycm_confirm_extra_conf = 1


let g:ycm_goto_buffer_command = 'same-buffer' "[ 'same-buffer', 'horizontal-split', 'vertical-split', 'new-tab' ]
let g:ycm_filetype_whitelist = { '*': 1 }
let g:ycm_key_invoke_completion = ''

I may also add that in order to make YCM work with full support, I built following from source:

Vim from source + all the latest patches applied into the source before the build. llvm + clang libraries (latest stable) built from source. YCM built with support againt fresh clang libs.

Also it's important to setup your .ycm_extra_conf.py file. (flags and includes mainly) here are mines: (scrol down if you want to see them all)

flags = [
'-Wall',
'-Wextra',
'-std=c++11',
'c++',

#Standard includes
'-isystem',
'/usr/include/c++/4.7',



#GTK includes
'-isystem',
'/usr/include/gtk-3.0',
'-isystem',
'/usr/include/glib-2.0',
'-isystem',
'/usr/include/glib-2.0/glib',
'-isystem',
'/usr/lib/i386-linux-gnu/glib-2.0/include',
'-isystem',
'/usr/include/pango-1.0',
'-isystem',
'/usr/include/cairo',

'/usr/include/gdk-pixbuf-2.0',

'/usr/include/atk-1.0',
'-isystem',
'-I/usr/include/gio-unix-2.0',

'-I/usr/include/freetype2',
'-isystem',

'-I/usr/include/libpng12',

#current dir
'-I',
'.',

#custom libraries
'-I',
'/opt/boost_1_55_0',
'-I',
'/opt/cryptopp-5.6.2',
'-I',
'/opt/llvm_install/include'
]

If you do GTK+ coding then this list may be of help to you. btw, if you wonder what does -isystem mean right before include dir, it means that YouCompleteMe (clang/clang++ compiler) will now show warnings and errors from these headers. (which are false positive 99% of the time)

btw, Sinastic checking is done with clang compiler (background compiling) while building it self can be done with any compiler kind, of course.

Thanks!
