init.vim

" This is a very simple implementation of automatic :augroup -
" that is, whenever a vim script is sourced, that file will
" automatically default to a group name based on the path.
" It turns out this doesn't really break anything; scripts are
" still able to define their own augroups, it's just that they
" can't clobber other scripts' autocmds with a careless :au!

augroup init
  autocmd! init SourceCmd * exe 'augroup' expand('<afile>:~:r') | source <afile> | exe 'augroup end'
augroup end
