Use brew to make sure you are running the latest version: brew reinstall zsh --enable-etcdir
It will not behave as your /bin/zsh without --enable-etcdir
Change your default shell:
chsh
Speed up your login:
touch ~/.hushlogin
The big problem for Vim users is that by default, Vim does not use your shell environment. For example, I have installed the latest version of Ruby with chruby, but since Vim uses the system default environment I get this:
!ruby -v
ruby 2.0.0p247 (2013-06-27 revision 41674) [universal.x86_64-darwin13]
That means that the syntax checker is outdated, and I cannot run any extra gem like reek or rubocop.
To solve that, add this to your vimrc.vim file:
if has('gui_running')
set shellcmdflag=-ci
end
Now I see this:
!ruby -v
ruby 2.1.0p0 (2013-12-25 revision 44422) [x86_64-darwin13.0]
This solution only gives you your normal shell if you are running Vim on its GUI. I do not enable this on the shell mode because then, vim forks into the background:
