Guardfile

# Ruby guard file (need ruby >2.2 and bundler installed: 'gem install bundler')
# To make sure all the gems are installed, run 'bundle install' once in terminal
# Run lablogger::ll_setup_gui('dev') and fill out the resulting dev/credentials.R file
# Then you can use the Makefile target 'make gui_dev' to start the GUI in development mode
# For browser livereload to work, need the browser extension: http://livereload.com/extensions/#installing-sections
# If the delay is too short for relaunching the app, increase the grace_period
