Example configuration

" Required for operations modifying multiple buffers like rename. set hidden

let g:LanguageClient_serverCommands = { \ 'rust': ['/.cargo/bin/rustup', 'run', 'stable', 'rls'], \ 'javascript': ['/usr/local/bin/javascript-typescript-stdio'], \ 'javascript.jsx': ['tcp://127.0.0.1:2089'], \ 'python': ['/usr/local/bin/pyls'], \ 'ruby': ['/.rbenv/shims/solargraph', 'stdio'], \ }
