Ability to (re)inject Herd dependencies?

[legecha]

Imagine a scenario where I install Herd and get it setup, then I install Oh My Zsh which overwrites the .zshrc file.

It would be great if there was a way (including or preferably via command line) to re-inject the necessary Herd configuration, such as PHP, NVM, etc.

Maybe a tiny bit related to this: #360

Also, I'm not sure if it would cause other issues, but what about an external file (either generated or clever enough to check possible paths) that can be sourced instead of adding them into the zshrc explicitly?

As for being able to toggle/override the settings, what about something like:

if [[ -f "~/herd.sh" ]]; then
  source ~/herd.sh
else
  source /your/path/to/herd/injections/file.sh
  # or maybe just hard-code them in here?
fi

Meaning a person could just touch ~/herd.sh to disable temporarily?
