# Unfortunately this bug (https://github.com/ruby/ruby/pull/5646) prevents us from using
# Ruby's native Module.const_source_location. Instead we have to fudge it by searching
# for the file in the configured autoload paths. Doing so relies on Rails' autoloading
# conventions, so it should work ok. Zeitwerk also has this information but lacks a
# public API to map constants to source files.

# This method does the following:
#
# 1. Runs Primer's classify routine to convert entries like mb: 1 to mb-1.
# 2. Runs classify on both options[:class] and options[:classes]. The first
# is expected by Rails/HTML while the second is specific to Primer.
# 3. Combines options[:class] and options[:classes] into options[:class]
# so the options hash can be easily passed to Rails form builder methods.
