What should I use to correctly replace deprecated URI.escape

Question

I need help understanding what is correct way to replace deprecated URI.escape

> URI.escape('space ^%$')
(pry):12: warning: URI.escape is obsolete
=> "space%20%5E%25$

Current implementation is this:

def escape(*arg)
  warn "URI.escape is obsolete", uplevel: 1
  DEFAULT_PARSER.escape(*arg)
end

so, just using DEFAULT_PARSER seems to work:

> URI::DEFAULT_PARSER.escape('space ^%$')
=> "space%20%5E%25$"

but also explicitly stating the parser seems to work as well:

> URI::RFC2396_Parser.new.escape('space ^%$')
=> "space%20%5E%25$"

What I'm looking for is the context on the Ruby change, so an informed decision could be made.

• why was it deprecated
• why was it moved to RFC2396_Parser? Should we expect new URI parsers?
• are there plans to switch URI::DEFAULT_PARSER?
