A lazy-loading RVM package for Zsh.

RVM Lazy-Loading for OMZ/Zsh

This plugin allows RVM (Ruby Version Manager) lazy-loading in Oh My Zsh (and perhaps other zsh installations). In my testing, my shell startup time was reduced from 0.45 sec to 0.20 sec (using time zsh -i -c exit).

Installation

Oh My Zsh!

*Important: If you did not install RVM with the option --ignore-dotfiles (or if you are unsure) you must first disable RVM loading. This is done by removing any entries in ~/.zshrc or ~/.zprofile of the form (or similar to):

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

or

export PATH="$PATH:$HOME/.rvm/bin"

once you do this, you may proceed with the installation instructions.

Clone zsh-rvm-lazy into your custom plugins directory.

git clone https://github.com/FrederickGeek8/zsh-rvm-lazy ~/.oh-my-zsh/custom/plugins/zsh-rvm-lazy

Then add zsh-rvm-lazy to your OMZ plugins list.

plugins+=(zsh-rvm-lazy)

What is Lazy Loading?

Lazy loading is the concept of only loading things when they need to be used. In the context of Zsh, RVM is automatically loaded and setup when you launch your shell. While some may find this desirable, there is the undesired effect of delayed being able to interact will your shell (the launch time). By enabling a lazy-loading package, your shell startup time will most likely be reduced, sometimes significantly.

Possible Issues

• I have not tested this, but its likely that RVM will no longer autodetect Ruby versions in directories.
