terminal vim not loading .zshrc

Question

My terminal vim configuration is not loading the ~/.zshrc. Zsh is the environment login shell. What is the proper configuration for this situation?

Here are some measure

Answer 1

From the manual:

Commands  are  first  read from /etc/zshenv; this cannot be overridden.

[...]

Commands are then read from $ZDOTDIR/.zshenv. If the shell is a
login shell, commands are read from /etc/zprofile and then 
$ZDOTDIR/.zprofile. Then, if the shell is interactive, 
commands are read from /etc/zshrc and then $ZDOTDIR/.zshrc. Finally,
if the shell is a login shell, /etc/zlogin and $ZDOTDIR/.zlogin are
read.

From what I understand,

set shell=zsh\ -i

should work.

Answer 2

I found an handy solution. As the only thing I really need is all my aliases, I added a function to my ~/.zshrc file:

function zshalias()
{
  grep "^alias" ~/.zshrc > ~/.zshenv
}

Then execute source ~/.zshrc && zshalias.

In your vimrc you only need:

shell=zsh

Everything then works perfectly with no suspended tty output!

Answer 3

The accepted answer doesn't work as expected. The actual solution should be putting the aliases and other ~/.zshrc content into ~/.zshenv. The only thing needed in ~/.vimrc is set shell=zsh without any flags.
