DESCRIPTION For some Vim options, it may be helpful to make a particular setting only for certain buffers or windows. Some options offer this, but when the option is only globally scoped, this cannot be easily done. For example, the 'scrolloff' option can be set to a high value to effectively center the current line in the middle of the window. But one may only want this for certain filetypes, or only in a particular window. HOW IT WORKS When a buffer- or window-local global option is set, autocmds are set up that modify the global option depending on the currently active buffer / window. Because there can be buffer-local autocmds, but not window-local ones, the approach taken is slightly different. USAGE :SetBufferLocal                         Show all global options made buffer-local. :SetBufferLocal {option}?                         Show the buffer-local value of global {option} (if                         set). :SetBufferLocal {option}={value}                         Set the global {option} to {value}, but only in the                         current buffer. Effectively turns {option} into a                         buffer-local option. :SetBufferLocal {option}<                         Remove the buffer-local value of {option}, so that the                         global value will be used. Like :setlocal {option}< :SetWindowLocal                         Show all global options made window-local. :SetWindowLocal {option}?                         Show the window-local value of global {option} (if                         set). :SetWindowLocal {option}={value}                         Set the global {option} to {value}, but only in the                         current window. Effectively turns {option} into a                         window-local option. :SetWindowLocal {option}<                         Remove the window-local value of {option}, so that the                         global value will be used. Like :setlocal {option}< Alternatively, you can also directly use the following API functions. Note that these do less error checking than above commands. GlobalOptions#SetBufferLocal({option}, {value}) GlobalOptions#ClearBufferLocal({option}) GlobalOptions#SetWindowLocal({option}, {value}) GlobalOptions#ClearWindowLocal({option}) EXAMPLE Place the current line in the middle of the window by setting 'scrolloff' (a global option) to a large value, but only for the current window:     :SetWindowLocal scrolloff=999 Place the current line in the middle of the window by setting 'scrolloff' (a global option) to a large value, but only for a certain filetype (best placed into ~/.vim/ftplugin/{filetype}.vim):     :call GlobalOptions#SetBufferLocal('scrolloff', 999)     :let b:undo_ftplugin = 'call GlobalOptions#ClearBufferLocal("scrolloff")' Note that we use the API function in the undo command to avoid an error when the buffer-local option has already been unset. (And also for setting it, to be consistent and because it's slightly more efficient.)
