Handy stuff for running gems via bundler, without bundling them

bundle-local.sh

bundle-local () 
{ 
    local command="$1";
    if [ "$command" = "on" ]; then
        if ! grep --color=auto -qs Gemfile.local Gemfile; then
            echo "eval File.read('Gemfile.local')" >> Gemfile;
            bundle;
            git update-index --assume-unchanged Gemfile Gemfile.lock;
        fi;
    else
        if [ "$command" = "off" ]; then
            sed -i '/Gemfile.local/d' Gemfile;
            bundle;
            git update-index --no-assume-unchanged Gemfile Gemfile.lock;
        else
            echo "Usage: bundle-local <on|off>" 1>&2;
            return 1;
        fi;
    fi
}

Gemfile.local

group :development do
  gem 'debugger'
  gem 'spring'
end

group :test do
  gem 'minitest', '4.3.0'
  gem 'tconsole', '1.2.8'
end
