bundle config path

The location to install the specified gems to. This defaults to Rubygems’ setting. Bundler shares this location with Rubygems, gem install ... will have gem installed there, too. Therefore, gems installed without a --path … setting will show up by calling gem list. Accordingly, gems installed to other locations will not get listed.

[~/.../jekyll-learning/p1-t1-iaas-Jorge-Acevedo(master)]$ bundle config
Settings are listed in order of priority. The top value will be used.
local.sinatra

Gem github-pages

• github-pages gem

1. Add the following to your project’s Gemfile:

  gem 'github-pages', group: :jekyll_plugins

1. Run bundle install

Jekyll is already installed

You are not required to install Jekyll separately. Once the github-pages gem is installed, you can build your site using jekyll build, or preview your site using jekyll serve.

• For more information about installing Jekyll locally, please see the GitHub Help docs on the matter.

html-proofer

HTMLProofer is a set of tests to validate your HTML output. These tests check if your image references are legitimate, if they have alt tags, if your internal links are working, and so on. It’s intended to be an all-in-one checker for your output.

Add this line to your application’s Gemfile:

gem 'html-proofer'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install html-proofer

~/.../sytws1920/ull-mii-sytws-1920.github.io(master)]$ cat Rakefile 

desc "sytws: bundle exec jekyll serve --watch"
task :serve do
  sh "bundle exec jekyll serve --future --watch --port 8080 --host 10.6.128.216"
end

... # more tasks

require 'html-proofer'
desc "test links in the build web site"
task :test do
  sh "bundle exec jekyll build"
  options = { 
    :assume_extension => true, 
    :disable_external => true, 
    :empty_alt_ignore => true,
    :file_ignore => [ %r{categories} ]
  }
  HTMLProofer.check_directory("./_site", options).run
end
