Gets the value of an option. The behavior of this function matches that of |:set|: the local value of an option is returned if it exists; otherwise, the global value is returned. Local values always correspond to the current buffer or window, unless "buf" or "win" is set in {opts}. Parameters: ~ {name} Option name {opts} Optional parameters • scope: One of "global" or "local". Analogous to |:setglobal| and |:setlocal|, respectively. • win: |window-ID|. Used for getting window local options. • buf: Buffer number. Used for getting buffer local options. Implies {scope} is "local". Return: ~ Option value
