Running phantomjs from a Ruby on Rails application
I'm interested in using Phantomjs and I'd like to run it from my Ruby on Rails application. However, this is a command line tool (i.e. I'd need to run something like phantomjs rasterize.js http://raphaeljs.com/polar-clock.html clock.png in my terminal). How would I execute a command line tool from my app?
Use backticks in your ruby code e.g.:
output = `phantomjs rasterize.js http://raphaeljs.com/polar-clock.html clock.png`
