My projects are all under /Users/username/workspace/my_project where /Users/username/ is $HOME.
I want macvim to always have the home as /Users/username/workspace/my_project instead of /Users/username/.
I understand set autochdir sets the home to whatever the current file's directory is, but this is not what I want.
Also I'm using NerdTree if that helps.
Do you want Vim's working directory to be ~/my_project?
Add cd ~/my_project to your ~/.vimrc.
Do you want all your plugins and colorschemes to be loaded from ~/my_project, however silly it is?
See :help runtimepath.
