I thought someone might find this quick tip useful, so I’m writing it up.
The Challenge
I have a blog that has a fair amount of posts now, with some of them being as old as 2012.
I worry that there are some dead links about.
Solution: Using the html-proofer gem and a RakeFile
- Open your blog’s
Gemfile - Add
gem 'html-proofer'to the file - Create a
RakeFile
Now you’ll pull down html-proofer in your bundle install. So how do we get it to actually do the installation?
Modify your Rakefile to add something along these lines (my current one can be found here):
require 'html-proofer' # Ensures we have the html-proofer library available to use
def run_htmlproofer() # The function that will run the proofer, so that we can re-use it between our two rake tasks
options = {
assume_extension: true, # Assumes html file extensions
:typhoeus => { # The options for the curl library that's used.
:ssl_verifypeer => false # This will stop you from getting errors when certs can't be parsed, which doesn't matter in this case.
},
allow_hash_href: true, # Won't fail for local links
url_ignore: [/edit\/gh-pages/] # This is because all my pages have a link to edit them, which will fail when generated locally.
}
HTMLProofer.check_directory("./_site", options).run # Calls html-proofer and uses the Jektll _site folder
end
task :test do
sh "bundle exec jekyll build"
run_htmlproofer()
end
task :testwithoutbuild do # For when I just built the site and I'm doing this a bunch of times
run_htmlproofer()
end
How to Use it
Once you have the Rakefile in place, you should be able to head to that directory and run rake test or rake testwithoutbuild which will parse your links and help you out.
I just ran it and ended up updating 20+ links so it’s definitely a great check!
That’s it!
