gem_path

WARNING: THIS IS CURRENTLY AN EXPERIMENT

A tool for manipulating $GEM_PATH.

Features

• Supports pushing and popping directories from $GEM_PATH.
• Updates $PATH accordingly.

Synopsis

List gem directories:

$ gem_path

Pushes a directory onto the front of $GEM_PATH and set $GEM_HOME:

$ gem_path --push /path/to/.gem

Pops a directory off of $GEM_PATH and resets $GEM_HOME to the next directory:

$ gem_path --pop

Install

wget -O gem_path-0.0.1.tar.gz https://github.com/postmodern/gem_path/archive/v0.0.1.tar.gz
tar -xzvf gem_path-0.0.1.tar.gz
cd gem_path-0.0.1/
sudo make install

PGP

All releases are [PGP] signed for security. Instructions on how to import my PGP key can be found on my blog. To verify that a release was not tampered with:

wget https://raw.github.com/postmodern/gem_path/master/pkg/gem_path-0.0.1.tar.gz.asc
gpg --verify gem_path-0.0.1.tar.gz.asc gem_path-0.0.1.tar.gz

Configuration

Add the following to the ~/.bashrc or ~/.zshrc file:

source /usr/local/share/gem_path.sh

System Wide

If you wish to enable gem_path system-wide, add the following to /etc/profile.d/gem_path.sh:

if [ -n "$BASH_VERSION" ] || [ -n "$ZSH_VERSION" ]; then
  source /usr/local/share/gem_path.sh
  ...
fi

This will prevent gem_path from accidentally being loaded by /bin/sh, which is not always the same as /bin/bash.

Uninstall

After removing the chruby configuration:

$ sudo make uninstall
