Self contained vagrant box to simulate github pages environment for local development.
After cloning the project into a folder, cd to it, and:
vagrant up
vagrant ssh
cd /vagrant
bundle exec jekyll serve --watch --force_polling
You can access the site from http://localhost:4000
PS: first time vagrant up is executed, it takes quite a long time to complete. This is normal (767.87 seconds in my case). It compiles and install ruby2.2.0 and bundles all the gems reguired by github-pages
PS II: --force_polling is related to an issue described here: Jekyll regeneration doesn't work inside Vagrant
PS III: Beware the problem of corrupted static files (js, css, ..). This is because of bug with virtualbox on shared folders: I add a line of text to my CSS file, garbage comes through the browser My only solution is to delete the file and recreate it.
