This plugin integrates neosnippet.vim in vim-lsp to provide Language Server Protocol snippets. You can use both Vim's built-in omnifunc or asyncomplete.vim for completion.
This plugin requires neosnippet.vim, vim-lsp and their dependencies. If these are already installed and you are using vim-plug, you can simply add this to your vimrc:
Plug 'thomasfaingnaert/vim-lsp-snippets'
Plug 'thomasfaingnaert/vim-lsp-neosnippet'
Otherwise, you can install these using vim-plug as well:
Plug 'Shougo/neosnippet.vim'
Plug 'prabirshrestha/async.vim'
Plug 'prabirshrestha/vim-lsp'
Plug 'thomasfaingnaert/vim-lsp-snippets'
Plug 'thomasfaingnaert/vim-lsp-neosnippet'
By default, snippet integration is enabled for all language servers. You can disable snippets for one or more servers manually as follows:
autocmd User lsp_setup call lsp#register_server({
\ 'name': 'clangd',
\ 'cmd': {server_info->['clangd']},
\ 'whitelist': ['c', 'cpp', 'objc', 'objcpp', 'cc'],
\ 'config': { 'snippets': 0 }
\ })
call plug#begin()
Plug 'Shougo/neosnippet.vim'
Plug 'prabirshrestha/async.vim'
Plug 'prabirshrestha/vim-lsp'
Plug 'thomasfaingnaert/vim-lsp-snippets'
Plug 'thomasfaingnaert/vim-lsp-neosnippet'
call plug#end()
