Automatically switch NVM versions when entering directories which contain `.nvmrc`

auto-nvm.sh

#!/bin/bash

# Run 'nvm use' automatically every time there's a .nvmrc file in the directory.
# Also, revert to default version when entering a directory without .nvmrc
enter_directory() {
if [[ $PWD == $PREV_PWD ]]; then
    return
fi

PREV_PWD=$PWD
if [[ -f ".nvmrc" ]]; then
    nvm use
    NVM_DIRTY=true
elif [[ $NVM_DIRTY = true ]]; then
    nvm use default
    NVM_DIRTY=false
fi
