Vim settings per directory
According to the mantra, to search for a shortcut when a task becomes repetitive, I've finally searched for it and found a plugin, which looks for
_vimrc_local.vim files (in the parent directories (and $HOME)).
Now, I can have a single
_vimrc_local.vim file in the directory where all my b2evo related directories/branches reside - and override my global settings therein; It gets sourced/executed whenever I'm opening a file "below".
Update: as noted on Reddit, you could also use the following code in a vimrc file (e.g. ~/.vimrc):
:au! BufRead,BufNewFile /path/to/project/* setlocal noet
I still like the approach of having local override files in the directory structure though, which might come in handy for projects: if somebody has installed the plugin already there's no need to edit any .vimrc file (if the project ships the _vimrc_local.vim file in the project's root directory).
