Mostly what I'm suggesting is asking the user to copy the settings they want, rather than sourcing a file in the repository that may contain arbitrary options. So something like: " Settings to match Git's style/indentation preferences. " " You can put these straight in your .vimrc if you want to use " them all the time. Or if you want to use them only inside " certain directories, wrap them like this: " if match(getcwd(), "/path/to/your/git/repo") " au Filetype c setl ...etc... " endif " au FileType c setl ...etc... That means they won't automatically pick up new options if they change, but that's the point. They should be inspecting and deciding which options they want to take. The conditional above definitely has some flaws. It relies on the working directory rather than the location of the file (which is the same as your plugin; yours is just picking it up implicitly from calling git). And once the autoloaders are set up, I think they'd trigger for any C file, even outside the repository directory. Ideally we'd combine the autoloader for BufRead and FileType, but it seems non-trivial to do so. I think: au BufNewFile,BufRead /path/to/git/* if &filetype == "c" | setl ... | endif works, though it's a little clunky, as each line would need to repeat it. There might be a better way. I'm not that familiar with doing tricky things with vim's autoloading. But my point is mostly that the value in the information is saying "here are some useful vim settings you might want to use". I don't think we need to solve "here's how to trigger some settings for some directories" for everyone. We should let them integrate the settings as they see fit. -Peff
