Friendly URLs

By default, Rails applications build URLs based on the primary key -- the id column from the database. Imagine we have a Person model and associated controller. We have a person record for Bob Martin that has id number 6. The URL for his show page would be:

/people/6

But, for aesthetic or SEO purposes, we want Bob's name in the URL. The last segment, the 6 here, is called the "slug". Let's look at a few ways to implement better slugs.

# Replace Jekyll's handling of the Redcarpet code_block (which already adds
# support for highlighting, but needs support for the very non-standard
# "code fences with line highlights" extension).
# Since this is currently depending on Redcarpet to cooperate, we are going to
# be naive, and only allow line highlighting when a language is specified. If
# you don't want any syntax highlighting but want to highlight lines, then you
# need to specify text as your language (or it will break), like:
# ```text{4}
