Getting "$(prompt_agnoster_main)" instead of cool-looking prompt

[ridhwaans]

Using Mac, antigen, iTerm2
In .zshrc, the theme doesnt work with these lines

source $HOME/.zsh/bundle/bin/antigen.zsh
antigen theme https://github.com/agnoster/agnoster-zsh-theme

example output

Last login: Thu Jul 25 22:26:21 on ttys000
$(prompt_agnoster_main) cd ~
$(prompt_agnoster_main)

but changing these lines, the theme works

source $HOME/.zsh/bundle/bin/antigen.zsh
antigen use oh-my-zsh # Load the oh-my-zsh's library.
antigen theme agnoster  

does the theme not work without loading ohmyzsh

See my PR #114 for the simple fix

Do you have setopt promptsubst enabled? You need that.

Closing as dupe of #35. Let's take the discussion over there and decide which fix approach is better.
