对gutentags的设置

gutentags.vim

let g:gutentags_modules = ['ctags']

" config project root markers.
let g:gutentags_project_root = ['.git', 'Makefile', '.root']

" generate datebases in my cache directory, prevent gtags files polluting my project
let g:gutentags_cache_dir = expand('~/.cache/tags')

" change focus to quickfix window after search (optional).
let g:gutentags_plus_switch = 1
let g:gutentags_generate_on_new = 1
let g:gutentags_generate_on_missing = 1
let g:gutentags_generate_on_write = 1
let g:gutentags_generate_on_empty_buffer = 0
let g:gutentags_ctags_extra_args = [
      \ '--tag-relative=yes',
      \ '--fields=+ailmnS',
      \ ]
let g:gutentags_ctags_exclude = [
      \ '*.git', '*.svg', '*.hg',
      \ '*/tests/*',
      \ 'build',
      \ 'dist',

      \ '*.pdf', '*.doc', '*.docx', '*.ppt', '*.pptx',
      \ ]
