chnode

Changes the current Node. Basically what you get if you s/ruby/node/g with chruby, so huge props to @postmodern for their work!

Features

• Calls hash -r to clear the command-lookup hash-table.
• Fuzzy matching of Nodes by name.
• Defaults to the system Node.
• Optionally supports auto-switching and the .node-version file.
• Supports [bash] and [zsh].
• Small (~100 LOC).

Anti-Features

• Does not hook cd.
• Does not install executable shims.
• Does not require Nodes be installed into your home directory.
• Does not automatically switch Nodes by default.

Requirements

• [bash] >= 3 or [zsh]

Install

wget -O chnode-1.0.0.tar.gz https://github.com/colinrymer/chnode/archive/v1.0.0.tar.gz
tar -xzvf chnode-1.0.0.tar.gz
cd chnode-0.3.9/
sudo make install

Homebrew

chnode can also be installed with [homebrew]:

brew install chnode

Or the absolute latest chnode can be installed from source:

brew install chnode --HEAD

Configuration

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

source /usr/local/share/chnode/chnode.sh

System Wide

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

if [ -n "$BASH_VERSION" ] || [ -n "$ZSH_VERSION" ]; then
  source /usr/local/share/chnode/chnode.sh
  export PATH=$HOME/.nodes/.current:$PATH
  ...
fi

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

Rubies

When chnode is first loaded by the shell, it will auto-detect Nodes installed in /opt/nodes/ and ~/.nodes/. After installing new Rubies, you must restart the shell before chnode can recognize them.

For Nodes installed in non-standard locations, simply append their paths to the NODES variable:

source /usr/local/share/chnode/chnode.sh

NODES+=(
  /opt/node-0.12.7
  $HOME/nodes/v5.1.1
)

Auto-Switching

If you want chnode to auto-switch the current version of Node when you cd between your different projects, simply load auto.sh in ~/.bashrc or ~/.zshrc:

source /usr/local/share/chnode/chnode.sh
source /usr/local/share/chnode/auto.sh

chnode will check the current and parent directories for a [.node-version] file. Other Node switchers also understand this file: https://gist.github.com/1912050

Default Node

If you wish to set a default Node, simply call chnode in ~/.bash_profile or ~/.zprofile:

chnode v5.3.0

If you have enabled auto-switching, simply create a .node-version file:

echo "v5.3.0" > ~/.node-version
