vim - Does the order of the sections of code in my _vimrc matter? -

how sections of code in _vimrc file interact each other?
current file looks following i'm wondering if matters if line such filetype plugin indent on @ start or end of file?
matter if line filetype plugin indent on repeated twice in file?
should pathogen settings near start?

tl;dr: do, don't; use logical structure simple complex.

pathogen wants settings appear @ top, because modifies way other scripts loaded (explicitly via :runtime, or side effect of calling autoload functions).

the order of :set doesn't matter (unless have conflicting settings), , mappings or autocmds define activated after startup, can put them anywhere.

in general, i'd recommend logical structure, starting basic stuff pathogen, settings, plugin configuration, followed custom mappings , more involved adaptations autocmds.

also, i'd avoid putting filetype-specific stuff ~/.vimrc; rather, put corresponding ~/.vim/after/ftplugin/<filetype>.vim script , use filetype plugin on.
