README.md

A theme for ZSH with host/root highlighting for easier server hopping.

Install

1. Install https://github.com/robbyrussell/oh-my-zsh
2. Add onemightyroar.zsh-theme to ~/.oh-my-zsh/themes
3. Open ~/.zshrc and update theme via ZSH_THEME="onemightyroar"
4. Run source ~/.zshrc to reload shell
5. You're good to go

Flagging remote hosts

To highlight remote hosts, add an environment variable SERVER_HOST_TYPE='remote' to the system PATH. This makes it easier to identify which system you're running on:

TODO: Update this to flag tunneled connections automatically, without explicit ENV config.

Root

Root will always highlight red by default.
