Maybe RSS / Atom is not all the rage these days, but I find them very useful.

Adding an RSS feed to my Jekyll-based website:
Incredibly easy… I thought!

  • Add this line to the site’s Gemfile: gem 'jekyll-feed'
  • add this line to the site’s _config.yml: plugins: - jekyll-feed
  • run gem install jekyll-feed

And, voilá, there is now a «michaelbach.de/feed.xml» (actually, an Atom feed).

Thanks to the authors of this gem!

However…

Yes, there was a feed.xlm file – but all links were directed to localhost!

Finally I found the solution here: https://github.com/nielsenramon/chalk/issues/48
JEKYLL_ENV=production bundle exec jekyll serve

So it looks like the jekyll-feed code looks at the “production” environment variable. Grrr… that should be in the documentation!

After digging a bit more, I find this is a Jekyll thing:
“site.url Contains the url of your site as it is configured in the _config.yml. For example, if you have url: http://mysite.com in your configuration file, then it will be accessible in Liquid as site.url. For the development environment there is an exception, if you are running jekyll serve in a development environment site.url will be set to the value of host, port, and SSL-related options. This defaults to url: http://localhost:4000.”
